Ok, heres something for those turbo over SC guys to chew on. My baby has grown up.

It's a 2012 GT500. with the '13s coming out soon, I was able to pick this up for 2500 under Xplan. It's stock in this picture but mods are on their way. It's got 550 at the crank. A smaller pulley and tune will add about 75-85 to the wheels. This thing is mean as hell! Just the sound when I start it gives me wood! Hanging out with one of the first to get the Pettit s/c tomorrow, vIce gRip (dan). Although I've moved on, I'll still lurk around every now and then so feel free to drop me a line, especially if you have a question about my past or current vehicle.
maybe in a few years I'll buy this one from you too
Now that was funny slvrstreak!
Pettit should have a release in about 1 month. Ya'll will just have to wait
. Developing anticipation is a good form of marketing.
Turblown---I am sure a properly designed turbo system will work just fine--heck Pettit has them on the diaso. Its not a street driven/high milage application but the point is--a properly designed system that is properly installed and tuned will work ok. Too many turbo systems are not.
Problem seems to be a number of people just dont know how to design/install and tune one. It IS a more complicated system imho. But what do I know? I am the most unknowledgeable poster on the forum.

I guess I was fortunate. I had the same capacitor wire break but did not detonate the engine. With mine I would loose all power including starting, the dash would light-up with every cel and two fuses would blow. We would change the fuses and it would run for several hours so it caused us to think that what ever the, problem it was fixed during the several changes that were made.
I kinda lost count but I think the s/c was removed at least 4 times looking for the problem. Erick and Ray found the break while doing checks on all the other wires in the harness (fourth time for the wire checks), but this time we also removed the covering. Hell we removed and checked just about every electrical connection in the car.
I did a routine compression check and both rotors are well within compression requirements.

You STOPPED putting money into the car? How--please tell me how?????
Heck I just installed a box of "hose Candy" vacuum line fittings.
I just read something funny in the new issue of Car and Driver Magazine. It was a test drive with the new Camarol ZL1 with the supercharged engine. The person in charge of making this car happen stated " We tried a turbo version on the engine first, but the car burned up before I had a chance to drive it!" He actually said that! Thats why they went with a supercharger.
It seems that superchargers are getting better and more and more developement is being done. Now straight cut gears, six lobes ( versus four), magnesium rotors, better bearings, water cooling, and different air intake designs are all being implemented. Sweet!
This magazine also had some info on the "Hot V" turbo set up that has been tried. That thing looks wicked! Exhaust and intake ports change position. The header/ turbo was in position where the intake used to be ( on a v/8 engine). I think BMW uses some of this design?
But bottom line is superchargers are starting to get more respect.

I don't think that superchargers need more respect. People that aren't retarded and/or don't feel the need to justify their time and money spent by bashing the efforts of others will allways feel good about their hobby.
I wouldn't trade any of the time I spent tinkering on the 8, nor would I ever want a turbo over a supercharger on this car.

i deleted the thread swoope. i had over 40 views and no comments. So I guess what I had observed was nothing.
Basically what i saw while looking at some ap logs was my alternator voltage went over 14 Volts ONLY after my fuel injectors were past a certain duty cycle. The fuel pump was already in its high speed mode before this occured. Injectors are not maxed out.
My hot alternator voltage is usually mid to high 13's which is OK. But during the observational period, it was a 14.2--14.4V range that NEVER occurs otherwise in my logs. I thought that was curious and also I thought it may be of some importance while tuning.
I was also wondering if this was happening to anyone else.
