Opinions wanted on 9L and ACR

[Terminator02]

^^^ There are modifications, and there are modifications. The Arrow HC kits and 9L kits are going to be highly regarded because they are as close to OEM spec, design, testing, tuning, etc. as you will get. If you are worried about future value, these are the only mods I would consider.

That said, modding a '17 ACR-E, especially an SE car or other highly desired spec, is taking a larger gamble because the cars are potentially collector-worthy and most collectors want a bone stock car at auction time (with little to no miles). Thus, if your endgame is maintaining the highest possible value, you really need to not drive it anyway -- so why mod it?

Now, I think these kits make far more sense on a car that already has miles anyway. Or, say a '16 ACR with standard colors. Those cars do not stand out for their stock spec, but might actually stand out (and be more desirable) because of an awesome Arrow upgrade like the 9L.

I'm caught in the middle. I have a great stock spec on a final year car, but I plan on driving the wheels off the thing and never selling it. So, I like the idea of the 9L and my only real concerns are long-term reliability and parts availability.

Well Prefix is not going anywhere. Plus I would think the fixed cam Vs vvt may not only more accessible but more fixable down the road. If a bearing happened to go on a HC car, the fixed cam is fixable where on vvt it will not be.

Interesting comment. I'd take a stab at "Dick Winkles Special". A metallic screw/bolt on badge, to be affixed where the GTS stick on badge is located. Available from Prefix (only) to those cars that are equipped with BOTH packages HC and 9,0L, which they would verify with the installers.

Unfortunately I don't think people outside of devoted Viperholics would know who Dick is. We need something that would connect with people. I do think this would be worth exploring with Prefix. They could send out special name plates to those with verified 9.0L conversions. These cars might become as valuable as the ACR/TAs! Maybe they could be called ACR/R for ACR-Race edition or ACR/HiPo. or maybe Viper/R or Viper/HiPo for you non-ACR guys. You guys with this upgrade should push Prefix on this.

Yeah, it would definitely need to be only available from Prefix and only on HC and 9L cars as it only makes sense to create another "special edition" if it truly is bonkers special (like another 700+ rwhp ). That would be awesome.

Have we exhausted all of the snake names? Cobra, Rattler, Medusa, Python, etc.?

You should have kept it in 2nd gear at 1:43 at 92mph, the next turn you would have killed that McLaren. You dropped to 58 mph in 3rd gear, which dropped you about 125 hp compared to 2nd gear. You were already bouncing off the rev limiter, just had to do that another tenth of a second and you would have blown post him on the (left) outside. Coming out of a corner at 58mph in 3rd gear you may as well have been in a Yugo.

He didn't shift to 3rd. He put his hand on the shifter but did not make an upshift. The next shift is an upshift to 3rd.

I really think that someone with a 9.0L should reach out to Prefix and suggest they come up with a name for the package. They must have a marketing department that would be able to come up with something.

To answer a couple questions here, we have thought about naming it, but the heads/cam is called our 700 kit.
The 9L is the 9L and then you have the 9L xtreme.
There were more people involved than just Dick to make the 9L and the Xtreme package come to life.

There are no authorized installers for the 9L or Xtreme package. We at Prefix are the only installers, our partners send your engine to us and we perform the modifications in our facility. You can buy the crank from Callies and figure out the details yourself, but you are on your own at that point.

We have plenty of new and stock take out parts, for the VVT setup. We also have special cams made specifically for us with oversize bearing journals. That way if an engine comes in with a damaged cam bore we can bore it oversize, and still use the block.

As far as durability of the 9L setup, we tested it on our dyno simulating 1/2 mile full throttle passes, with upshifts. The first hour or two sounded cool in the office, but after the third day it was quite annoying!!! lol
After all that we tore it down and inspected the block and rotating assembly. Everything looked and measured good!

You would be surprised on how small our marketing dept is lol

[FrankBarba]

I have taken a few Viper to Prefix for this Upgrade. Once they come back they are a beast.

[Arizona Vipers]

What are you talking about AZ? At 1:43 at 92 in second you're well into the cut out. And yeah sure I could have made a move on the left just after that but remember I wasn't racing buddy and wasn't going to make an aggressive move at that corner as I knew he then had to move out to the left anyway himself around that corner. Just a bit of fun AZ. We don't need to both end up with very expensive repairs at the end of this buddy!
Btw would love to see some videos of your moves! Any links?

What I mean is the 1 10th or so you'd have given up bouncing off the limiter you would have gain much more back accelerating after that turn. No offense that's just my advice on that part of the track. If you watch all the videos of Chris Winkler breaking all those track records you'll see him hold gears and bang the limiter a lot, giving up a tiny bit of time, but gaining it back by not have to immediately downshift again. Which tires are you running again? He should have let you buy anyway, you were killing him in the turns. Awesome driving and great vid thanks for sharing.

[Arizona Vipers]

I've had limited track time on my 9.0 Extreme, had a shock break on my first outing etc. But it's night and day as far as acceleration goes, my ACR has never been able to pass GTR's, Cup Cars, GT3's etc on the straights, and now the 9.0 walks away from them. It really evens the playing field against those paddle shifted beasts. And with the wing it can put the power down. I was really shocked at being able to be full throttle shifting into 2nd gear once the tires were hot. If you do the upgrade and find that it upsets the balance like you are worried about, just keep it in a higher gear until you get used to it. You could basically keep a 9 liter in 3rd gear and never shift (except for long straights) and be very surprised at your lap times.

I think you guys are missing an opportunity to really leave a legacy.

I am with you 100%, what about a Viper Emblem with the 9L in the center.

I bet doug shelby could make some really nice ones, if Prefix was ok with that.

How about Doug collaborating with Prefix?

You would also need a certificate of authenticity with VIN from Prefix. That would nail it. At some point you could create a 9.0L registry.

whats the real cost for the 9 upgrade?

Call VE, Woodhouse or Prefix

please get one, I would love to hear it SCREAM at lime rock!

Ok, but the name "Yenko" certainy didn't connect with people when it came out, aside from Cameroholics, and those who bought a car from Don Yenko's dealership.

I think if the premise should go forward, it should have a name that connects with the 9.0L (I chose Winkles as he created it for the Viper). Arrow 9.0L or Prefix 9.0L would work also... I think unrelated names to the 9.0L, like various snake names or marketing names car companies come up with, would be tacky.

This should be for all documented Vipers that have the Arrow/Prefix 9.0L, not just he ACR's.

Anyway, I had been thinking of adding 9.0L vinyl decal, above or below my vinyl 'ARROW Racing Engines' logo that is already on my Viper. Just need the time to find a decent custom maker.

[Scott_in_fl]

We've seen Callaway SC757, AMS with the Alpha 10 and Alpha 12 GTR's, and we know of Tesla and their P90, P100, etc.

So, how about something that incorporates the hp output or other measure of power.

How about AP7 for the HC package (for Arrow/Prefix 700 kit), and AP9 for the HC and 9L combo?

I thought about Arrow Racing AR7 and AR9, but in the current environment anything with an AR designation may not go over very well. It does sound badass though.

This is what I did for my HC Stage 2 ACR. Now some might find it goofy. IMO, it’s cool.
If I did 9L I’d come up with something.
I’d love for Prefix to have package name that’s market focused.

As far as ‘mods’, I agree it depends on buyer. I’d pay more for a car with these mods by Prefix, VE or Woodhouse. A motor they’ve been thru is a safer one than a stock one, IMO. And I’m of the opinion that these mods aren’t like other mods.

It’s also available for Gen IV cars.

[IHOP]

What about just putting the 9.0 where the 5.0 is on mustangs. Nine point O!
