Heffner dyno results--843 rwhp (corrected) = 31 HP gain!!!!

[GaryA]

As I posted yesterday, Jason Heffner finished putting his larger aftercooler and larger injectors on my car. A few months ago my car dynoed at 812 rwhp (corrected) when Jason tuned it with his blower system, making it the highest horsepower, non-nitrous blown Viper in the world!

With the new aftercooler Jason was able to pick up an additional 31 rwhp with his skillful tuning bringing it to 843 rwhp and 792 rwtq (corrected). Once again, this raises the bar for a supercharged Viper (no nitrous). No dyno tricks were used (i.e., icing of the engine, race fuel, etc.) As soon as Jason was finished I rode off into the sunset (albeit a little sideways!!). Of course, dyno results are one thing, but the proof is on the track.

For those who are new here or just tuning in, my car has the following setup:

- single blower making 12 psi of boost
- 93 octane pump gas (no race fuel or nitrous)
- Heffner's large aftercooler
- 50 lb/hr injectors
- ported/polished heads with larger valves
- stock '97 Viper cam
- fuel management system
- forged pistons
- Heffner's expert tuning expertise

For all you guys who have cars being supercharged at Heffner's, you're in for a real treat. For you guys that have yet decided to make the plunge, I invite you for a test ride and you will never look back!

Here's the dyno sheet:

Thanks again to Jason and all his hardwork and great engineering!

 

[Paolo Castellano]

Well Gary, it looks like you are the undisputed supercharged king of the dyno! Congrats! All that power with the stock cam, fantastic!

 

[J DAWG]

Simply amazing. I guess that equats to right at a grand at the crank. I bet that is one hell of a ride and all you have to do is turn the key and go.

Enjoy and be careful!

 

[Torquemonster]

Gary - you have a truly awesome car! That is a very well engineered combo - hope you get a lot of fun out of it and kick some serious ***** out there! There's gotta be some bikers around there that are just ...well, you know, far too smug... show em your taillights

1001 HP to be exact!!! hahaha!!

 

[Daffy Duck Viper]

Wow. THAT sure is an exciting technological achievement. Congratulations to you, Gary (owner) and Jason (creator).

Gary - CONGRATULATIONS to you and Jason for a job well done...AGAIN! One of the many things that I like about your car is the conservative appearance. It shows no sign of the massive HP just waiting to be unleashed on the next victim (i.e., ricer, stang, and everything else).

Be careful with that sideways stuff!

 

[Jason Heffner]

Hey kevin, how are you liking your "new" car?

 

[Dr Roof]

I thought you had 844 RWHP before? Regardless awesome numbers and Awesome Car.

Thanks Dr Roof! The results before were 812 rwhp corrected which equates to 844 rwhp uncorrected (as published). We picked up 31 rwhp corrected.

I'm very interested in your drag racing event in KY that you're putting together. I really hope it comes together and all these high HP cars can compete together to decide who's the undisputed King of Vipers!!!

 

[Kevin Stitely]

Jason - The sound of the Corsa system/Random Tech cats is awesome. The car finally sounds like one bad [******] Viper, just like Gary's...well maybe not exactly.

BTW, the EBC greens are exactly what I expected...no more brake dust or squealing!

 

[treynor]

Wow - congrats! It's nice to see the bar continuing its upward path. I look forward to seeing your track results!

Thanks Kevin!! The credit all goes to Jason. He's a master when it comes to supercharging and Vipers.

Thanks Ben! Dyno king is one thing, but track results are the only thing!! Are you planning on going to Dr Roof's shootout?!! I remember that you had your sites on my car--I'd love to line up with you!!

I would certainly pay to see that race.

I spoke with the track again today and they are working hard to give me a garuanteed date. As soon as I have that I will really push for a great event.

I think this HP thing is gonna get wild! The bar will continue to raise. We need to have an event before all the 800 HP cars are considered Slow!

Again awesome car and I can't wait for some track action. Take your to the track and post some numbers real soon!

Good deal!! Let me know if you need help putting this together. I had a lot of fun at Bowling Green before VOI.7 and think it's a great venue. We'll definitely be there!

 

[Gerald]

DANGIT!! time to upgrade...NOT..... STOP IT YOU GUYS! I'm not trying to spend more money!!!!

 

[SmokinV10]

Gary,
Those numbers are just straight IMPRESSIVE!!! Congratulations! You are now the mac-daddy all mighty of any viper running on SC alone! Great work to Jason Heffner!!!! I'll say that Jason is the definitely the king of supercharged vipers!

 

[1TONY1]

Gary...I am just sitting here shaking my head repeating the word "sick" over and over. Congrats once again to you and Jason.

 

[Moundir]

good God this is the package I'm shooting for Awesome job Jason, I cant wait to hit the lottery so I can have one of these puppies on my slow snake

 

[Casey]

Gary,
Congrats Again! You and Jason both!

Enjoy your stay on top of the Supercharged Viper World! Those numbers are awesome!

2 months and counting!

 

[Baddasp]

Congratulations Gary. Your car is absolutely SICK. Have fun and be safe.

Jason great job. You are truly a master of supercharging. Hey, btw..when is my turn for the intercooler upgrade..I can't wait

[Sean Roe]

Nice work guys

Sean

 

[GONABITE]

NOW THATS A DYNO GRAPH!!!

 

[OutThere]

Get him to work on a Gen1.........

 

[Anthony - 98 GTS]

WOW - Great numbers!!!

I noticed you have a stock '97 cam. Do you think you would pick up additional HP by changing cams?? Any reason you stayed with a stock cam??

 

[Bad02ViperGTS]

Congrats to you Gary and great job Jason... As we all know Jason does a great job on what ever he works on....Viper, Mustang and even BMW.....


By the way Gary you still owe me a ride!!!!!!!!!!!!

Kick asp! But I'm confused, what's Treynor's RWHP when not on nitrous? Or is the distinction that, unlike him, yours does not have nitrous available to tap into?

 

[Gerald]

I think Treynors was something like 836 RWHP still shreading the tires on the dyno. Please correct me if I'm wrong. Once he straps it down, who knows what he'll get out of it..
