First of all I'd like to thank Dennis and his team for humoring me throughout my tuning phase of this project.
The first time I mentioned my idea with this V6 to Dennis I could tell he was skeptical, and to tell you the truth I was unsure this project would get out of the garage and nevermind the 20 mile drive to Dennis for the dyno tune.
So, after some major reconstruction of the engine compartment and removal of components any car loving person would cringe to even touch I faithfully turned the car over and IT STARTED. So I drove it to Dennis for the initial tune. By the way it stalled at every red light and idled like a sick diesel engine.
Dennis was suprised I drove it to him...and honestly I was amazed it even started.
Over the next couple of tuning sessions Dennis found various minor problems which were quickly fixed. The one problem haunting me was a major vacuum leak in the lower intake area. This turned out to be two problems. One, my 42 lb fuel injectors were not sealing correctly and the second was a warped piece of welded aluminum letting air bypass the entire intake system.
Once that was fixed I drove it back and was able to give Dennis a car he could actually complete a dyno tune on.
So, with a stock 3.65 inch pulley, 25% UDP, 42 lb injectors, 310 LPR fuel pump and a fully ported and polishe lower intake Dennis was able to dyno 229 wheel hp and 260 lb ft of torque out of the aged V6!
Since that initial tune I have added Water/Methanol injection and a 3.1 inch pulley giving me 11 lbs of boost. Dennis also installed an Auburn posi with 3.73 gears, rear end girdle and an over haul on the seals and bearings.
Did I mention Im not using an intercooler?? As of this post the vehicle is dynoed at 281 rwhp and has the potential of running high 12 second quarter mile times (with a skilled driver I might add)
Dennis could have got more power but after a short discussion it was decided that since this is a daily driver and I am limited by boost temps to leave it at the conservative tune on 93 octane.
Thanks again Dennis...I'll get pics to you soon
