Final tune session (New Heffner system)

[Mark Red GTS Cooper]

Well, after a few more dyno pulls, and adjustements, we buttoned up the Viper and hit the road for a test ride,,

It hits extremly hard, it pulls and pulls and then pulls some more (To bad the roads were cold). But we got it to hook once, and it launced hard (The cars up ahead sure came up quickly)

My final numbers were: (SAE, NOT UNCORRECTED)

* 756.1 Rear Wheel HP
* 732.5 Rear Wheel Torque

Not to bad (GRIN) for a car with no head work, no porting, and a stock 2000 cam. I am running TNT headers, Ross forged pistons, T&D rockers, and that is about it......

We also made a really trick hood latch since we could not get to the stock one because of the intercooler. No poking holes, or bending, very simlpe, very fucntional.

Jason, many thanks, you engineered and great system, it was great to work with you on the new system.

Mark, Congrats! That is one bad Mo Fo now. My car goes there in the next week or so. I can't wait for Jason to work his magic on my car! Paolo

Hey Mark, did you change pulley size by any chance (increase boost)? or was the gain from adding an Intercooler only?
Thanks and congrats.

 

[THEMASH]

Never mind Mark, i just saw the other post (SC for Sale).
Thanks and have fun.

Mark;

Congrats to you and Jason--never had a doubt. I'm hoping you got to enjoy the car today. First really clear day around here for awhile. Life is good...

 

[Mark Red GTS Cooper]

Hi Walt,,

Yes, I had the car out for a little test ride, and the state of VA loaned me a closed course for my test runs,,

Very fun,,,

Let me know when you want to come out and go for a ride,

Mark

awesome #'s mark! hope you enjoy it. i cant even imagine having 750+ hp....good lord!

mash -&gt; when is your car going in for the sc?

 

[Jason Heffner]

Glad to hear you're enjoying it Mark. You can keep the change on the extra horsepower. Not bad for a four day turnaround time. Just remember to be careful on these cold roads, a car with that much power can be very unpredictable. Have fun.

In 3 weeks "i hope"

Congratulations Mark! Now get out there and smoke those tires!

Jason has a very nice S/C package that he put a lot of thought and engineering into. He can consistently install these with predictable results at a price that nobody in the industry can beat. And the best part is, he did your car in 4 days!! Now that's incredible! That's right, 756 rwhp in 4 days! Wow!

NICE Lately it seem like everyone has a 700+ RWHP Viper

Very nice! That much HP is alot of fun, Trust me! Nothing like boosting!

Now you need to make Reservations and bring that bad boy to the viper powerfest!

 

[Jason Heffner]

Hey Mark, how about posting some pictures and and a dyno sheet! It's just not fair to keep it all to yourself.
