Dyno'd Vortech With 3.12 With A Custom Tune
 

Yesterday I took my car to Church Automotive tunning to get a custom tune since I changed from the stock 3.33 Pulley to the 3.12 pulley. My car stock with the 3.33 pulley put out 335 whp with 302 lb torque of a Dyno Pack (6.63 lbs boost) , yesterday on the the dyno pack similar conditions just changed the pulley first run without a tune 343 whp and 323 lbft torque (9.28 lbs boost) after some tunning and adjustment 384 whp and 323 lbft, this was like the tenth run on the dyno so the car was getting a little bit hot.


so here is a breakdown for people who are thinking bout changing their pulley.

Vortech with 3.12 pulley custom tune ss box - 384 whp and 323 lbft (car was pretty hot) 9.99 lbs of boost

I am very pleased with the car and the supercharger, at first with the stock pulley the car was a little hestitant and had some issues as far as power, but now the car is an absolute beast and drives perfect with power throughout any gear.

Pretty good numbers:) enjoy!

Very nice. Congrats and enjoy the new power. :cool:

Good hp numbers, just don't like the tq numbers. Do you have a printout of the results you can post? What's up with the -1 itrader?

superchargers dont have great torque numbers but hey, its still 100 lbft better then stock. ;)

Yea, I know and your right at the same time. I'm just trying to safely avoid conflict with others on the FI debate, which is better.

nice numbers

that tq is nothing a 75 shot can't fix :cool:

+1 on a printout

nice setup.
can't wait to install the 2.87 pulley!

I don't have a scanner at home but I will scan it tomorrow at the office.
