Message Alright, I've got a build thread going at 3zc that I periodically update, but since I got some actual data today I thought I would share.

I've been trying to find a local dyno day for a while now, with no luck. So I finally got around to calling Bigshot Dyno down in Stow. I live in a city of 51k people and with 100k people within 5 miles, and I have to drive almost an hour to the closest dyno. Boo.

Anywho, I did my first dyno this spring with a chip tune and 12psi and put down a measly 290ish hp.

Since then I got Nistune and using my ZERO tuning experience I dialed in the chip tune on the street and turned up the boost to 15psi. I also installed a doolz intake and selin translator.

I've got a set of Ash Massives V3 and 2.5" intake piping on the way for install this winter and I wanted to get another baseline prior to that mod, and a comparison from where I was at this spring.

Runs were on a DynoJet reporting STD Horsepower.
Run 1 broke up a little so we didn't log it.
Runs 2 and 3 were nearly identical, within 1hp and 1tq at 15psi.

Run 4 I turned the boost controller back down to 12psi to get a comparison to this spring (plus the dual intake and tune)

Photobucket

15psi- 351whp and 367tq!!!!!!
12psi-331whp and 339tq!!

VERY pleased with these results. My goal of 450whp should be attainable with 17psi and breather mods!

I don't think my mods are in my profile, I haven't been able to access it since the site went down way back when.
