Before & After Arrow/ViperExchange Heads & Cam dyno's and videos.

[FLATOUT]

Now that we are rolling through a few of these builds I thought that I would create a thread with before and after dyno graphs and videos for Gen V owners to check out. Every car is a bit different but I use the same dyno for before and after runs. All runs are SAE corrected and I typically make 3-4 pulls (hoods closed with fan) on both the baseline and the post dyno sessions. I dyno the cars in baseline form as they show up at ViperExchange. If they are brand new they typically loosen up a little with miles but I dyno them as is. Cars shipped to us are dyno'd as they arrive for their baseline as well.

Not every build does a before and after so I will add to this thread as we get more cars completed and on the rollers!

First car is my 15 GT with ARH headers/no cats, Under drive pulley, smooth tubes, and about 6,000 miles on the heads and cam setup.

Gains: 120.68 RWHP 96.15 FTLBS

I like the timing of this post! Looks rad, thanks for posting, Andy.

[Murpowa]

Great thread Andy - impressive gains!

[VENOM V]

Very interesting. I've seen the Bad Boyyz headers in person, craftsmanship is gorgeous. Do you think that the headers account for the improved dyno numbers over the ARH?

[99RT10]

Great gains on Heads/cam. Well done Andy!!

[rlhay2]

Very good info, thanks!

They are a fantastic header, but honestly I would say it's very hard to say. The baseline numbers on the car were not where we typically see Gen V's on this dyno. Most Gen V baseline numbers on that dyno are anywhere from 540-550 so 517 was a bit lower than we usually see. I am more excited to see the car performing where it should be performing if that means anything.

Wow 660 rwhp ! Well Done !

[FLATOUT]

Wow 660 rwhp ! Well Done !

Thanks! I expect most builds to make between 630-660 rwhp depending on how they are setup and or smal supporting mods. The package is an advertised 100hp gain over stock.

[345s-bspinnin]

Thanks for posting the before/after results. What I see here is irrefutable and predictable results of these very well sorted setups.

[Nine Ball]

Crazy NA numbers, for as mild as these cars sound in person.

[Simms]

Great package. Would really like to add this at some point.

[Jdmuscle]

Me liking this thread a lot... Andy.. As usual.. Good post. Thank you. Average of 650-660whp with heads and cam is awesome for this platform.

[G37Sam]

This is just crazy!! N/A driveable 660 whp is absolutely no joke!

[v10tt]

Those are very impressive gains!!
When will we see a side by side comparison between a 600+ rwhp full bolt on car vs. one of these Head and cam set ups?
I want to see what this set up does in a 60-150 mph roll on race with equal drivers.

Will the head and cam pull from the get go like the bolt on car vs. the Stock cars?

[7TH_SIGN]

Nice gains. This along with a TT kit would make me smile.

[7TH_SIGN]

It really is. In the Supra world on 93oct, you would see 6XXwhp max.

I am signed up for the Project X runway event in Texas on November 8th. I let Slowhatch know a couple of weeks ago if he wanted to sign up (I checked yesterday and didn't see his name on the roster). I also called Andres (345spinnin) and asked if he could bring his Heads and Cam Gen 3 out for some pulls since we make very similar power numbers. He did sign up for the event. I also called a few local bolton Gen V cars and Gen IV bolton cars to try and get them out. There are a few showing up so we should get a bunch of runs in with good comparable data.

I have said it many times and on more than one occasion to you I think, but I drive both of these stage 1 builds and the heads and cam builds back to back all of the time and the cars making around 650rwhp are obviously quicker than the ones making 600rwhp.

[v10tt]

Andy, I know it's obviously faster, just want to see them side by side to see how it pulls from the bolt on car. No doubt the H/C is faster , not disputing that at all.
Thanks for putting those cars together. Do some 60 mph roll ons to see how it does. It is what it is, the package makes great power and sounds sick.
Driveability seems to be on the $$, which is very important too.
Would be nice to get some Vbox data too from the different cars.

Yes Sir I will do the best I can to bench mark it against as many cars out there as possible. Doing it on the street is tough if you're looking for repeatable benchmarks to compare so I thought this would be a better route to go. There will be a great cross section of cars there and I know I have seen a couple Gen V bolton cars on the list. These will all be rolling starts just like TI. Most rolls will be from 60.

[v10tt]

Nice!!!, I'm sure it will win all the N/A wars. Looking fw to see how it pulls away.

The run with Andres (345spinnin) will be a very good and close race NA to NA. He has made as much as 640SAE and I think he has his car weight around 3190 without driver. I expect my car to come in around 3220 or so and I have a few lbs on him in the drivers seat so it should be very close. Regardless it will be a lot of fun to run his car as it's been one of the most consistant and fast NA Vipers in Houston for a long time, and went 195 in the mile NA.

Andre's car and your car Andy definitely have my interest peaked !!!

Agree I think we're both looking forward to it.

[345s-bspinnin]

Oh yes we are.

I have driven Andy's car and can tell you right now that this is going to be a very closely contested match. I have a couple of GoPros I will throw on the car. However, I won't put them outside (too much drag)....LOL. I need every advantage I can get against that higher powered, smoother shifting, more aerodynamic, and tighter geared Gen V.

LOL I'm still 50lbs fatter. And yes you can tell you used to work for the space program down here. Aerospace Engineers Mind > Classical Musicians Mind when it comes to going faster with less lol.

[allans]

Tony, Can you go full throttle from 60 in 2nd w/o spinning tires? Thanks, Allan

[Jack B]

i think which gear and what speed (the start), may be the deciding factor. If I wanted an advantage with the G5 HC, a 30 mph start in first gear, to the top of 4th (140). The caveat, we need to run DR's)

Cam must be the major contributor to the gains?

Have you put a similar cam in a Gen 4?

For this event, we start at 60mph rolling, then have 1400-1600ft of acceleration. We will likely finish in the high 140s range (perfect for a Gen V). My OEM geared Gen III with 28" DRs will end in the middle of the rpm range (5400rpm at 150mph).

[viper04]

Please keep us posted on the event. Looks like it's going to be fun!

Best part of this event is you and I can setup up any start speed or even go from a dig, so we can play around with start speeds as well if we want to make some hits at 20-40-60-80 we should be able to.

Cam must be the major contributor to the gains?

Have you put a similar cam in a Gen 4?

Arrow has run the package on a Gen IV motor in house and it made similar numbers. They made the move to forged pistons similar to the Gen V so you would see that move eat 10rwhp or so I would think compared to what the Gen IV would make if they stuck with the stocker.

I think the port work (larger valves), and cam do make up the greatest part of the gains. The Exhaust and ECU probably contributes to 40 and the rest makes up the other 50-60.

Andy,
Any plans to upgrade your website? The performance mods section lists quite a few items but no information or pricing. Im currently window shopping but for pricing i have to dig through old posts.

The Arrow head and cam package is a wicked deal. Bang for your buck awesomeness!

Yessir I need to get it updated. Been a bit busy with all of the builds going on but that needs to be a priority. Please email me anytime awheeler@viperexchange.com if you have any pricing concerns or questions. We are still offering our free install special on the heads and cam cars when you purchase a new car from us at $13,990.00

Andy,
How much power would the Heads and Cam package pickup if OEM headers and cats were used (w/ HP Tuner)? I'm asking as I want as stealth a package as possible for CA emission testing.

[Jack B]

It will not work will hpt, the Arrow pcm is doing some very complicated tasks

[donk_316]

This might be semantics here but I was under the impression it's your stock PCM reprogrammed and not the aftermarket arrow PCM.
For clarity sake.

You would want the ARH pipes anyways. Whole package built and tuned with those headers.

[Jack B]

I should have been clearer, the Arrow programming cannot be duplicated with today's version of HPT.

That might not be true if someone else brings out their own cam and tune. However, look back at all the bs and bluster about the promises of an imminent HC package.

[1evilviper]

a H/C set up with a 200 shot would be one hell of a rocket for roll racing

[Jack B]

Why not a 300 shot and save $12k

[TheStig]

I think a H/C car will be more fun off the spray. Eg on a road course. I'm with 1evil viper

[1evilviper]

Why not a 300 shot and save $12k

bc when you aren't spraying it, 650rwhp would be fun on the street, and idk how I feel about a 300 shot, im sure it feels awesome, but id cringe everytime I hit it...

[Jack B]

The cam would rob the car of hp when on the bottle. A lot of the nos would be going out the exhaust.

The ECU's are just hardware so wether I mail Arrow a factory box or the Arrow controller they both come back with the stage 2 calibration. And yes the package was built and tuned around American Racing Headers which is what we install at ViperExchange. The ARH's make more power up top. Dick spent a good deal of time calibrating three gen V's when this package was developed, the White mule car at Arrow that we own, my personal car, and Ben Keatings Gen V.
