My friend has a 2015 stingray and he is thinking about upgrading a few things to go out to the drag strip. He has a set of the sport cup 2's from the z06 that he bought from a friend. So we were wondering what rwhp would he need to hit a 150mph trap speed. That's his gole with the cup 2's because he wants the car to still be able to handle just as good on the road (so no drag radials). Will 1000rwhp be enough, or will he need more?

A lot more has to be looked at the these 2 facts. Rear gear, transmission set up. With the correct set up 850 rwhp will get the car to 150 in a 1/4 mile.

I was told by more than one guy in a c5 with 850 to less than 900 rwhp car was hitting 153 to 155 in the 1/4 mile. But these guys car really ran good also on the street..

So it is possible with sport cup 2's and 850 rwhp to get 150 trap speed? What else do you need? It has the stock manual in will he haft to change it or is it strong enough to handle the power? also will doing effect its lateral g cornering capabilities? Is there a vid of someone doing this? Sorry I don't know everything about this kind of thing.

Now I don't know that much about the cup 2 tires all we did was slicks or D/R tires. I don't see any stock clutch holding together to long on a track with 1,k rwhp in the car.

Plus I would not side step the clutch at 2500 plus RPM in the car. Then again riding it out of the hole will do about the same but at least I don't see this breaking the rear end out of the car.

3 are 4 guys in here good rwhp with stock rear end has broken the gears out of the car.

Only one car on this forum has posted a trap speed over 150 and it's LMR's car that makes 1200 hp. It was not on cup 2's either it had DR's.

robert miller

C5 with just around 1,k too RW hitting 160 mph in the 1/4. But then also they have the P/G trans also in the cars. I don't know what LMR is running as a set up.

I found the vid. The one where he went 168? What do you think he could have done on cup 2's or just not on dr's?

robert miller

Is this a full stock set up on front & rear tires. Other than the motor & blower on it.

I never saw 168 I just looked through the fast list thread and saw mid 150's.

It's hard to say what they would have went on cup 2's, it may have spun so bad they couldn't hook at all or it may have mph'd really similar.


If this is something you really want to do I would build a really stout engine that can handle way over 1000 hp and then just turn the boost up until you get to the mph you want.

Are you just looking for MPH or do you (or your friend) want to make a decent 1/4 mile pass? You are not going to get cup2s to hold for the hp level you are talking about for a 1/4 mile pass.

Well due to money issues and him wanting to keep the cornering capabilities the only change other that the engine, the changes to the drivetrain to handle the power, and the cup 2's that's all he wanted to do.

And here is the vid I was talking about:

Mainly for the 150mph trap speed but we were hoping in the high 9's but that's a little to hopefull I think.

Edit: did you mean c7's only on that run where you said it was in the 150's because I just realized that vid was in a c6😂

I can promise you that if you have anything remotely resembling "money issues" you don't want to build a car that traps over 150.

Edit: Also look up the rules regarding cars that trap 150 or more, are you ready to put a parachute on your car? Because that's just one of the things you'll need.

I think i found the vid of that lmr corvette you were talking about: www.youtube.com/watch?v=1Bixyj_ce1Y

Yes i am aware that i will need a parachute.


That 155 run by lmr, that was done on radials wasn't it? Me and my friend were talking and we started to wonder if they made dot approved racing slicks. Not radials but the ones you take to a road coarse? how would you do on a drag with them if they do make such a thing.
