Hey guys,
Just thought id become part of the community as i am now a 60degree v6 believer.
First and foremost my name is George and i am the owner of Pro Flow Fabrications in Melbourne, Australia. I specialise in all forms of turbo and race fabrication on all vehicles, but my main forte is V6's. I first started toying with the 3800 buick style engine in our local Commodores, slowly i have become Australia's front runner in turbo kit development for these engines. My turbo kit is a great seller on the Australian market.
As i was playing with these GM decided to throw a new v6 on our market(and world wide aswell). Along came the LY7 Alloytec v6. Now the ecu setup that GM decided to use with these engines has been the main and dominating factor as to why people wont touch these things. Now the LY7 was released on our market in late 2004, and really no one has done anything to them since the last 12 months. I must admit as there was no software to aid the process of modification we all stayed away!
Well for me the time had come to expand my market base so i was in need for a new test mule! The LSX market has been done to death here so there was nothing more for me to do there. I had a brief chat to friend of mine who just happens to be one of the propritors of VCM suit. He was more than confident that the LY7 could be tuned.
So i set about finding the perfect car in which a series 1 VZ utility with the LE0 alloytec v6(LE0's had only vvti on inlet cam) and a 4L60E. I then set about developing a turbo kit to suit.
I used an external gate Garrett GT3582R and a turbosmart 38mm wastegate. All in all with a 3" mandrel bent exhaust the kit was established.
I then handed the car to my friend for tuning duties. He had the car for over 2 months, the final outcome being that the vcm software can not be used to tune the ecu due to the torque recuction being the main gremlin.
It was at this point that i had reached boiling point with all this bullshit and bought an aftermarket ecu that was able to control the VVTi and FBW throttle. The ViPec V88 ticked all the boxes for me and i proceeded to have it fitted.
Apart from the auto being strengthend and a 3000rpm stall converter and also a set of 440cc injectors the car and engine are stock. Also the engine has only 8psi in it.
Below are some links of the dyno tune and our first outing at the drag strip.
Id really like your feed back guys and also any other forced fed alloyecs running around as id love to see more. The future for this car is to run 10sec passes on an internally standard engine. We might even convert the thing to E85.
Cheers
