I have a 08 base car with an A&A centrifugal supercharger. It dyno'd at 580 rear wheel horsepower. It still has the stock run flat tires.

I've seen a few YouTube videos of high horsepower Corvettes spinning out during acceleration...Z06's and Zr1's. Apparently the spin out/getting sideways can occur when a gear shift occurs at high speed.

I think it's recommended to get rid of the run flat tires and get some softer tires.

Some comments about how to drive this car? I'm wary to drive it in automatic with the pedal to the metal. I think I should drive it in Sport mode and paddle shift it to prevent a surprise upshift.

I'm not 100% naive. I had a 69 Corvette with a clone L88, I had the compression ratio machined down from 12:1 to 11:1. It was about 500 hp flywheel hp. It was a manual tranny. During a full throttle acceleration I could easily control the car, especially by using the clutch. I got some sideways slip on a drag srip, but never worried about loosing it.

So..I've never driven my A & A supercharged car above maybe 3500 rpm and even at that not at full throttle. I think I need to go to a drag strip...although the nearest 1/4 mile strip is in Bakersfield about 200 miles away. Spring Mountain in Nevada is another option.

Question: If I just slam the pedal to the medal in Auto, with stock tires, will the car just accelerate in a straight line?..with no getting sideways issues?

Thanks

 

My 2005 also has 580rwhp & from my experience, if you go WOT from stand still, you will only go up in smoke. I think if you leave traction control on, you should go fairly straight. The videos you are watching are probably people like me that turn off TC to have some fun. Good luck

 

LOL, yes you will have spin in first and second at WOT. Over 600HP you start spinning even in third gear pulls.

The good news is, the independent shafts and traction control on a C6 work very well - so long as you are going in a straight line.

Find somewhere safe and wide open to practice WOT pulls.

#1 rule as far as I am concerned: If you lose confidence in the car's traction, get off the throttle immediately! Most problems I've seen people have is staying on the throttle and trying to drive your way out of it by counter-steering. Unless you are racing for pink slips, don't do that.

And never, ever turn off traction control unless doing burnouts at the dragstrip.

And yeah, consider better tires, maybe even drag radials. But they do affect your handling. Everything is a tradeoff...

NT05's are nice if you don't want to go full drag radial. Anything but the stock run flats!

 

I have a 08 as well at 680 RWHP. The active handling and TC are incredible in our cars. Leave them on and have some fun.

 

I use Competition Mode. Allows some sideways shenanigans going around corners, but not too much.

Good street tires will really help. Bridgestone RE-11, Hankook R-S3, Michelin Pilot Super Sport, Toyo R888. Those tires will do pretty good with the exception of launching hard from a dead stop. For max traction from a stop you are going to want to run a drag radial. Those suck on corners though.

 

When you leave these two on don't they kill timing to keep HP down and to keep the car from spinning out???

 

I thought our cars actuated the rear brakes? Mine went metal to metal with lots of front pad left.

 

Maybe there is something wrong with my car, but it will just power through traction control. It makes a lot of noise and flashes yellow lights, but still spins like crazy. It may have something to do with supercharger, Edelbrock Eforce, I don't know. This is with either the Michelins or my drag radials, Nitto NT05R's.

 

I think the noise & flashing lights are telling you to turn off TC or buy spare set of rear pads.

 

You may very well be right, but I have replaced all the pads front and rear and it had no effect. Even when it was brand new and bone stock I had the wife in it one time and was telling her how great TC was only to stab the throttle from a traffic light and doing a burnout through the entire intersection. I caught hell for that. She thought I knew what it would do and just wanted to show off, which was the last thing I expected. Who knows? Maybe my TC is malfunctioning. I'm not letting a dealership touch my car now and I just keep it in comp driving mode all the time anyway.
