Any 9Liter Extreme owners in here

Would love to hear what you think of it. How’s it compare to stock? Did you go heads/cam first? How’s it compare to that?

Any supporting mods needed? Recommended? How does drivability change?

Anyone consider selling/trading theirs?

I’m kicking around many ideas but I simply can’t being myself to do a build on the orange TA... doesn’t feel right. Values have gone up and I feel like modifying it would put a halt to that. I Would love to find a Stryker painted GTS for a good price to build but I am not very patient either... and right now the ones available are significantly more than what makes sense (think a few are trying to swing for the fence and see if anyone willing to be crazy)

Thoughts? Opinions? Help a fellow viper owner through this mental conundrum.

Buy a 2013-14 base and build it to be the rocket you’re looking for. Values are reasonable and you’re going to build the motor anyways, so you shouldn’t care if it’s a re-powerd car or not. Maybe a lemon buy back would save you the cash to put TA brakes on it.

Really?

TA values may increase but how dare stryker owners follow suit. Your perception seems a bit skewed. Nevermind the fact that the majority of stryker cars were highly optioned, and thus, a higher MSRP.

In any case, of the few H/C TAs that have sold recently, the mod didn't seem to negatively affect the selling price

But did it help the selling price? Normally you never get back anywhere near the price of the modifications.

Please don't buy a Viper to worry about the value of it. Drive the wheels off of it. :)

I doubt the sellers received 100% of what they put into the car when they sold it. That said though, with Gen 5 vipers, if it’s been tore down and build, the bearing have been replaced. The bearing weigh on my mind from time to time and a part of my motivation to do a heads/cam or 9L car is to change the factory bearings.

^^^This^^^My ACR E was eating a quart of oil every 700-1000 miles, exactly why I had Arrow build the 9L on my 16 ACRE with 3K miles (insurance) not to mention the bump in hp/ tq is insane...hehehe

I feel like you’ve made some assumptions and created a place for friction where one isn’t necessary murpowa...

Nowhere in the statement that you quoted me saying did I say, “Stryker values cannot increase” I simply said that the people buying a car for a beautiful paint color and the folks buying a car that was a numbered limited run, record breaker brought into this world for one specific purpose, will likely care about different options differently...

This is Ofcourse only my opinion and could prove to be incorrect, but ultimately, it’s how I feel and what I believe so unless you’d like to shine some light to persuade me otherwise, I stick to my original statement... and I’d still feel better about modifying a Stryker painted car over a TA...

Regarding the recent ones with heads/cam that sold. I don’t think it hurt value exactly but I am 100% sure it narrowed the field of people who considered buying it. (I have spoken to a couple people myself that passed on them specifically for that reason)

Sapphirebob, that is precisely why I am having this conundrum. I want to just drive and build and enjoy my viper but there’s a part of my brain that feels guilty about modifying the TA. It still isn’t out of the realm of possibilities... just not the current preference.

Good points regarding the bearings parabs and space truckin. Hadn’t considered that thought process... how does your 9.0 drive compared to before when off the track? Is it still fairly road friendly or do you feel you sacrificed a lot of regular drive ability?

Agreed, this is the wrong car to invest in. Especially if you drive it.

Well my 9.0 extreme on the road drives pretty much as it did before the modification. You just know you have a lot more under the hood when you let it rip that's all.

Sorry just read this again. Wasn't a TA a track pack version of the gen V Viper before the ACR(which of course is THE ultimate track version of the Gen V Viper) came out?? Apart from the limited numbers can I ask for my own information, what exactly is otherwise so special about the TA compared to say a Stryker coloured ACR that would make the TA say more desirable or more valuable in the future-unless I am reading your words wrong? Also what sort of record breaker was the TA? Did it break multiple track records or be the fastest manual rear wheel drive car around the Nurburgring? Just want to know what is so special about the TA compared to say an ACR that's all. Please enlighten me. Also don't get me wrong. I like the TA like I do other Gen V's as well- but would like to know what makes it stand out apart from them making fewer of them. Thanks

The viper TA was released earlier than intended with the sole purpose to take back the Laguna seca record from the corvette ZR1. There was a lot of hype, press, etc around that purpose upon its release.

Personally speaking, I feel it is a middle ground for folks that don’t track their cars enough (or have the money) to buy an ACR but want to be more capable on the track than a typical GTS or SRT for example. Very purpose built edition of the viper and the limited run an numbered cars/VIN seems to bring more value to many folks.

In my opinion, the ACR is the pinnacle of performance in the viper world but based on my readings and feedback I’ve gotten, a lot of folks want something a bit more tame or with a few more “creature comforts” and the TA is a solid compromise.

Excellent analysis and, yes, the TA is a cherished and special edition. I too would be concerned about modifying it if you are worried about maintaining the highest possible resale value. However, the cost to transition into another Viper, or to pick up a second for modifying purposes, probably is not worthwhile. Plus, if you are driving your TA, then you are not maintaining the utmost resale value anyway. In that case, I say throw the heads and cam or 9L into the TA. That would be a sick car.

Stradman, do you notice a big difference in power in the lower rpm range ie. 2k thru 4k? in my stock 2014 gts, it seems like when you get to 5k rpms and higher is when you start to feel the full power.

Scott_in_fl that isn’t completely out of the realm of possibility. That’s why I was also asking for others feedback on their 9 liter setups... ultimately it will become a matter of did the right replacement car become available before I ran out of patience. Haha!

If not there will be a nasty 9 liter extreme Orange TA that I will drive until the wheels fall off.

Still not a bad outcome haha!

Yeah, I think if you look at the economies of it all, it probably makes sense to do what you want with the TA. Buying another car is more storage space, more insurance, more sales/use taxes, etc. All of that would need to be offset by the anticipated price appreciation that would come from keeping your TA stock. But then you'd also have to drive it less (how many miles does it have on it already?), and then hope that the market does what you want within the time frame that you're willing to wait. That makes you a car investor, which is generally a losing proposition. I think you find much more happiness and certainly less out of pocket near term costs (by not having 2 cars) if you simply do what you want with the TA. Will you kick yourself in 10 years to learn that your modded TA is worth $200k and unmodded ones are going for $250k? Maybe. But I think not.

I am in the camp as Stradman and I have a similar setup with my ACR - it is beast when I want it to be but otherwise it drives similar to stock. I do love the lumpy idle now (narley sounding). I do however, need to find a a way to lower the sound level

Hey Hans did you read my recent post in the other thread? . New mufflers are awesome and I lost 11 decibels in excess noise! Check it out.
.

There is always the option of picking up another engine to build. Just set the original aside and then go crazy on a second engine. That stand alone engine will retain value as well if built properly and sold down the road

That's a brilliant suggestion! How much more would that cost though? I've been reluctant to modify my ACR/TA with a 9 liter because of header heat (which Prefix could wrap so that might no longer be an issue) and the fact that I would be modifying a numbered special edition. Maybe I should just buy another ACR and put a 9 liter in that.... Yea, the wife would never go for it.

Did you do a before/after dyno pull?

No I didn't Jack. However I took it out for about 90 minutes today and as it was dry I gave it the beans and certainly the car from a butt dyno perspective still feels as brisk as it did before. Remember though the mufflers I now have are not restrictive at all. Same size pipe all along as before from the Prefix Sportscat to tailpipe. Only difference is the central pipe within the muffler is perforated with tiny holes to allow some of the sound waves to pass through the packing material. Centrally however the flow of gases resumes unimpaired so it makes sense that there is no increased backpressure. Honestly car is now a dream to drive. Its a bit quieter no drone. Should have been that way from OEM as far as I'm concerned. Before it was just obnoxious and anti social. It's still loud by most cars standards but a touch more civilised and importantly allows me on to the tracks I want to go on. It's not quiet enough to do the quieter tracks but thats ok.

I've looked into this as well, and it is definitely a viable option. You can find a Gen 5 motor on eBay every now and then in the $12,000 range. Of course, you're not entirely worried about the miles of a used engine as we're going to be building it out anyway. I would want to get the electronics from the used motor as well.

I thought you had some bad snow storms this week.

I'm down in the southeast so although we had some snow it wasn't bad and roads cleared up quickly. It was nippy of course(nothing like the northeast US had thought!)and it was dry and sunny for a couple of days and about 4 degrees Celsius. Perfect to drive!

Here's the equations and rules I typically use for car values:

1. (Community's Perceived Value) > (Market's Perceived Value)

2. (Community's Perceived Value) + (Mods You've Done) = (Your Perceived Value)

3. (Market's Perceived Value) - (Mods You've Done) = (Potential Buyer's Perceived Value)

4. (Market's Perceived Value) + (Mods You Paid Big Name Shop to Install) - ((0.1)*((Car Mileage)/1000)*(Mods You Paid Big Name Shop to Install)) = (Potential Buyer's Perceived Value)


I'm not bothered by what my car might be worth, and that's not going to stop me from doing whatever I want to it, but then again, if I started hearing about OTAs going for $200,000, knowing the above rules, it damn sure would make me have second thoughts. I would likely return my car to stock, and be contemplating what SirHiss is talking about.

The numbered cars will likely always carry a higher resale value, solely because they are numbered. Even though there might be fewer TA 2.0s made, they aren't a "limited production series". If a manufacturer will build as many of a thing as are ordered, and they just don't sell many, it's going to take a while before those are worth something. Take the McViper, for example. Begin production with a cap in place however, and then number each one, well that makes them more desirable. And I stand to say more desirable than a 1-of-1 ACR.

So, going back to SirHiss' original query, I too am curious to hear from anyone who's actually had work done?

I was recently at Sebring and my last run had oppportunity to run with another Yorange ACR and it clearly had work done. No stock Viper could have the ability to walk away as it did on the straights without engine work. (My friend said he knew the Viper. Was at Barber few weeks back and confirmed it has "work" done.) I starting poking around and apparently there are 3 different stages available? First are heads and cams (~7-9% increase in hp), Stage two bumps up engine to 9L (~17% increase in hp) and then there's the "Extreme" stage 3 that is supposed to increase horsepower/torque by ~25%?

Problem is, I'm told the parts alone for the Stage 3 is almost $27k by themselves. Then, there's still the labor to install.

Apparently, the stage 3 is still very streetable and reliable and trust that representation. However, I just can't wrap my head around the costs??

I'm really curious to hear from those who have the extreme package if they feel it's worth it?

I think you'll find that adding N/A horsepower is quite a bit more expensive that adding FI horsepower. That said, I've always viewed the 9L option as a very cost effective mod for a G5. You get basically more than you can handle on the street, it remains track-able since it's not FI with crazy hp and a wild powerband, and is apparently very drivable and reliable. It's almost the car that should have been, which is a theory that I've had -- that FCA gave us an overengineered race car in the ACR and left it to us to handle the easy part (install what is basically an OEM quality race kit). Nothing else really explains the way, way overengineered aero and why this car has 1,700 lbs. of downforce but no more hp than a standard Viper. Moreover, everyone who tracks the car agrees that it could easily handle quite a bit more hp to work through, and take best advantage of, all of the downforce (especially Luca Stolz).

Why would they do that? Because it is far easier for us to add the power than for them to do it (with regs, emissions, etc.). In fact, motorcycle mfg's regularly do this with superbikes. You buy the bike from Honda that was clearly designed to compete on a world stage, but it comes with 100hp stock. Then, if you know the right people, you source an HRC "race kit" that unlocks the full 210hp. They've done this forever.

Here is the current bike that you can buy if you have the $$$. https://www.motorcycle.com/manufactu...de-review.html

you pick - These numbers are all over the place, here are some ball park dyno #:

1. Stock- 530-570.

2. HPT - 590-610

3. HC - 660 - 675

4. HC & 9L - 680 - 710

5. Extreme: 725 plus (with 9L)

There are going to higher and lower numbers, let's say these are mean numbers. The above also assumes all cars have headers

Very interesting theory and hadn't heard that before. Only, if FCA really "overbuilt" the car why would our cars place such stress that the ball joints on "a arm" keep bending under load? Until I got all this replaced (at around $7k), I couldn't keep the car alligned.

It makes sense for us to make changes than huge costs for manufacturer, but going back to the original point I'm curious to hear from 9L Extreme owners how they feel about their cars? I'm also concerned as horsepower continues up, what is the next thing that you might have to chase?

Yeah, I'm convinced that internally the ACR-E was intended to be the Mic Drop for the best DOT approved track car platform available. The design of the car seems far more appropriate with slicks and 750rwhp than the setup that was required to be sold at your local dealer. Otherwise, the ACR-E does not make a ton of sense when the ACR was already there.

The ball joint issue sounds like one of those things that engineering just did not catch before the product was green lighted. That happens. Even owners of the SCG003 will surely identify some issues that the Glickenhaus crew missed. But those are usually smaller items that are easily worked around with a re-designed part that SCG will push out to owners as they devise a fix. Our problem is that there is no more refining of the ACR-E because everyone has gone home and the lights have been turned off.

I drive my 9 liter extreme on the track only and love it. No issues after about 5 track weekends so far. The car has been breaking NasaProRacing.com TTU time trial records

Callout received Space Truckin!

I have one for you. How about you post some pictures and provide an update on your 9L hotrod! You have one of the best ACR’s made!

I usually don’t comment on the future value of Viper threads and my “blue Viper” is worth more than your “orange Viper” speculation. I don’t have any current plans to sell my Viper so I may have a different perspective. When I consider where I can get a naturally aspirated V10 with 810bhp and a manual transmission, I plan on and hope I can keep my GTC forever! For those selling your cars, I wish you all the best with your sale. In my opinion, market supply/demand and the one buyer that writes a check is what your car will be worth. Anything before that is pure speculation.

Back to the OP, I have a Prefix 9LX conversion with 2,000 miles on it. I am very happy with the conversion. I have been doing roll racing and runway events. I have multiple pulls well past 170 mph and one at 197 mph. For a naturally aspirated motor, the top end is very strong. Wide open throttle in 3rd, 4th and 5th gears will circulate your blood faster – guaranteed!

I had one of the first 9LX conversions and had some initial perturbations, but those were worked out. I posted a thread here.

https://driveviper.com/forums/thread...rney+continues

In the thread I mentioned … “… modifications come with issues and perturbations. These issues may occur and that has to be accepted. I know this isn’t right for everyone. I accept those risks and enjoy the rewards”.

Modifying your Viper is a personal decision. It comes with risks and rewards… and… it costs money. There are many considerations (e.g. goals for the car, money, reliability, build quality, ownership term, emissions, warranty etc...) All of these considerations are personal and you get the privilege of making the decisions.

In my opinion, the 9LX conversion is a great upgrade. Prefix does a great job on all their conversions (H/C, 9L and 9LX). One of the pro’s for the 9L and 9LX conversions is you get essentially a new motor. Give Scot at Prefix a call and he can discuss your goals, budget and considerations so you get a solution you will be happy with. You can also send me a PM if you want to talk off-line.

Good luck with your modifications. I hope you are enjoying your Viper as much as I am.

When I consider where I can get a naturally aspirated V10 with 810bhp and a manual transmission, I plan on and hope I can keep my GTC forever! For those selling your cars, I wish you all the best with your sale. In my opinion, market supply/demand and the one buyer that writes a check is what your car will be worth. Anything before that is pure speculation.

Back to the OP, I have a Prefix 9LX conversion with 2,000 miles on it. I am very happy with the conversion. I have been doing roll racing and runway events. I have multiple pulls well past 170 mph and one at 197 mph. For a naturally aspirated motor, the top end is very strong. Wide open throttle in 3rd, 4th and 5th gears will circulate your blood faster – guaranteed!

I had one of the first 9LX conversions and had some initial perturbations, but those were worked out. I posted a thread here.

In the thread I mentioned … “… modifications come with issues and perturbations. These issues may occur and that has to be accepted. I know this isn’t right for everyone. I accept those risks and enjoy the rewards”.

Modifying your Viper is a personal decision. It comes with risks and rewards… and… it costs money. There are many considerations (e.g. goals for the car, money, reliability, build quality, ownership term, emissions, warranty etc...) All of these considerations are personal and you get the privilege of making the decisions.

In my opinion, the 9LX conversion is a great upgrade. Prefix does a great job on all their conversions (H/C, 9L and 9LX). One of the pro’s for the 9L and 9LX conversions is you get essentially a new motor. Give Scot at Prefix a call and he can discuss your goals, budget and considerations so you get a solution you will be happy with. You can also send me a PM if you want to talk off-line.

Good luck with your modifications. I hope you are enjoying your Viper as much as I am.

Thanks for sharing your thoughts and agree with you. Years ago, I built up a Nissan GT-R to 1000 hp and when it ran it was a beast. Unfortunately, the heat soak issues had me on a first name basis with every tow truck at every track I ever visited and since then have established my parameters of reliability FIRST.

My "bolt ons" are great and now seem to be chasing once again for the next level, but your comments brought it home for me, thanks.

I think all you "cheaters" out there w/ these mods should be required to put big bright "X's" on your hoods, so the rest of us know to get the hell out of the way...

Here you go..:t1567:
