First Time On The Dyno

[SERPENT]

Put the truck on the dyno at SLP engineering today for the first time. SLP is in NJ at sea level and todays temp was approx 80. Rear wheel hp was 640--- torque at 638. Hp at the crank was 750 with torque roughly the same. Will be sending the PCM back to DC performance for an additional tune. Lots of fun for a first timer.Tried several times to upload the video--sorry no luck.

Very nice. Those are good numbers. :rock:

Very nice. They look very close to mine (672 rwhp/640ish rwtq) before the water/meth injection. Boomers heat exchanger would be another nice option and can be used in conjunction with the stock Paxton heat exchanger for even better cooling of the supercharger.

Had Boomer's heat exchanger on the truck. Took it off to be able to put the DC airbox on. Ran out of room. What about Meth injection? How much will that help, aside from the safety issue and what system do you reccommend?

 

[Dave T(BADVENM)]

You can trim the airbox funnel to fit the front grille. Heres a pic of mine that Joe from PNJ did 2 weeks ago:

The water/meth added about 30rwhp giving me a total of 702 rwhp. Torque increased about 10-20 i think. Mine is the Roe water/meth kit.

Mind you I'm running forged pistons. Not sure what you've got internally.

Did not consider triming the funnel--Good idea. All internals are stock and I'm running 8lbs. boost. Have not purchased the VEC III. Don't I need that as the controller for the Meth injection?

wish i would've known you were goin. i would've gone too! good #'s tho

Cost was $205.00 for two runs complete with DVD of test. Guys were great to deal with --even though they don't tune Viper products. I will PM you for the next round.

great numbers....and looks great too....

You don't need meth AND a larger heat exchanger.....the meth will allow for some more timing and really helps back to back runs....:rock:

How does the video look? BTW great numbers.:rock:

Nice numbers.:rock:

Also, I like the paint job. :rock: Who would have thought to combine black and red, the two slowest colors.
