Well, my little woman is working today so I was bored. So I took in a dyno tuning job to tune a 2004 supercharged Dodge Viper. Now before anyone goes off the deep end, I do know this is a Corvette board. But seeing how this section is FI forum. I just thought some of you guys and gals may want to know what the other guys are up to.

This Viper belongs to a local business man, I won't say what kind of business as he is fairly well known here and I don't know if he would appreciate me spilling the beans about his car. The Viper is a local car purchased new by the owner. It was modified by a local Viper tech at Timberline Dodge who I have known personally for about 30 years. This car has one of the new Paxton Novi intercooled blower kits making 8 PSI of boost. It is also equipped with an exotic traction control system that is used on the very high end road race Vipers. The heads were CNC ported by the cyinder head engineer that developed the original V10 Viper heads for Mopar. And the internals of the engine was highly modified for boost as well, the usual stuff like what we do, forged pistons, rods, roller rockers (shaft mounts) and a blower friendly cam.

After 3 hours of tuning, the final numbers were 644 HP and 622 Ft/Lbs And these numbers are on my Mustang dyno which is supose to be notoriously low. I was rather impressed with the power this beast put out. In the begining we had some problems with the traction control that was causing an erratic power curve, and I had a problem with getting a decent tach signal. Once these issues were resolved I could tune the beast. I went from a baseline of 568hp to the final number of 644Hp. I have no idea as to what it was stock but my friend tells me its in the high 400's. It was a fun way to spend a Sunday afternoon, not to mention I made a dyno payment with this job His license plate reads: BYE BYE

I will post a dyno sheet later.......

 

Awsome Tom. Wish you are closer to NY. Rick BTF is working on a getting a portable dyno here. I told him I will be his 1st customer.

 

You should have Rick look into this dyno. Its about as portable as it can be, you don't even have to put it into the ground to use it.

And it handles big hp as well. I didn't beleive it until I saw it first hand in person.

 

Very interesting indeed. Im lookin at 30" roller Land and Sea, and building a trailer/lift for it.
I will have to call that companies office and see if their pricing/leasing is competitive. Those are very nice dyno's

 

Hey TJwong. Nice Viper, does he race at any of the Pacific NW tracks? we have a local Viper that gets eaten up at our track by the Z06, but he isn't putting down what that beast is.

Hi Robert, no this guy just plays with this car. He doesn't road race it at all as of yet. He told me that he does intend to drive on a couple of track days at PIR. Right now its just an expensive toy, he can afford it as he has lots of disposable cash. On this car alone he has spent over $50k on it in mods, that is on top of the purchase price. From what I was told this car is only 8 months old, and my friend has had it in his possesion for the last 4 or 5 months out of the 6 installing all the goodies.

There are a couple pictures of the car on this site:
