TTiX 347 results with Precision 6265bb
My Turbonetics had a bearing fail last month, so we swapped a set of Precisions configured by TTi. They do a good job setting these up. Coming from a Turbonetics setup, they're pretty much a perfect fit except maybe small adjustment to oil drains and downpipes.
Then with Dr Phil's help, we got tuned just in time to race last weekend. We settled around 900rwhp, but got there with 3psi less boost. With a 150 shot it made 1050rwhp with converter locked. Off to the track!
1st run: Low boost all the way down made 10psi. No boost creep whatsoever. 1.68/6.8@104/10.5@134 is a slow as it will go.
2nd run: Dialed up 22psi and went 1.64/6.3@117/9.6@149. Gained a few mph over the Turbonetics setup, where I would have normally seen 146mph, and the IAT's seem better.
3rd run: 22psi + 150shot went 1.74/6.4@121/9.6@155. Had trouble using the extra power, gonna have to work on my setup. Got a videos of this setup on the dyno and running down the track.

On my last run we got a 1.5 60', but lost traction in 2nd gear and aborted the run. The trans seems to be holding up. Hit the shifts well and no flare between gears.

Damn that thing sounded like it was spinning about 3/4 of the track.... That prep must have been crap.... I'd love to see it on a well prepped track in some good air.

Definitely looked like a positive outcome test outting. You dont get any track guff for lack of firesuit and other equipment?
