Heffner Pulley/Tune Video

Yeah, I've got one.

I had the opportunity to visit Heffner's shop over in Sarasota last Friday. I had already installed his exhaust before arriving. Jason and his guys installed a pulley and tune while I watched. As others have noted before, the car really reacts well to his magic. Here's a video of the post-mod dyno pull and a couple photos. As you can see from the dyno results photo, the car made 621 hp and 576 tq at the rear wheels (corrected and smoothed).

Jason and his guys took meticulous care of my car. Towels placed to protect from scratches, tape on surfaces that might get touched etc. His shop is clean and neat. I'd recommend him without reservation.

I've been on the fence for awhile on this mod. Now that it is complete I wonder why I waited so long. Thanks Jason.

First photo is how the engine looks once the supercharger is removed. I had never seen the inside of the intercooler before.

GREAT stuff and post!
 
Sounds tough. Dammit. Now I have to get that exhaust.
 
Congrats on the new pulley... I'm sure it feels like a whole new car. Becareful, she'll smoke those rear tires, don't let it get away from you.

Thanks for the picture of the intercooler. I was wondering how it looked.

Great pictures and the video is awesome!
It does sound great! Go for it DBK!
 
P.S, Chris, was it actually tuned on the dyno or did Jason just load the tune he's worked out that gets sent out on the SCT?
 
Note to self:
Don't race Chris's white car.
 
Thanks for sharing the information. For me, that's the best sounding exhaust I have heard.
 
Great Post Chris!!!!

Manny
Good point to self.....
I'll remember that as well!

We'll still be able to challenge him with Heriage and Blue.

Wish you would reconsider Indy...

Give it a second to load. It's a high res copy.

He did confirm A/F ratio and power on the dyno, but there was no additional tweaking done to his standard 93 octane tune.

Gary- Thanks for the hi resolution video link. It is much better quality than the link I posted. Sound quality is better too.

Great meeting you. Good luck with your killer Viper. :thumbsup

Chris, how about the other 2 GTs? One with a pulley another with the Whipple and the 3rd with a TT?
 
I'm impressed. I want to see it in person in April. Sounded very, very nice.

Note to Manny: carry jar of tacks to even up the field.
