As for posting similar 1/4 times, how do you consider running .5 tenths/5-6mph faster "similar" performance? That's ridiculous. Stock for stock a ZR1 will hand a GTR its *** on a drag strip. Even with the GTR being AWD with all the driver aid features like said before. It's on a different level than the GTR and Z06 plain and simple.

Just joking, but seriously..ZR1's have went 10.7x's @ 131-134 100% stock. A 2012 GTR, even with its AWD and fancy driver aids won't touch that.

Some of these GTR guys remind me of how the import guys were about the Corvette back in the '90s; in pure denial.

I don't think you quite understand how well the LS9 responds to simple mods. The LPE 750 kit consists of upper/lower pulley, bolt ons/tune - on the *stock/untouched* Eaton and will trap 140-145 in the 1/4. And will back it up with 9-second E.T's all day long.

The LS9 has put down 800+whp on the stock Eaton blower (ported of course)


Here is the 750 kit. No porting. This car even has the stock manifolds and cat-back.

These cars have the power to do it all day long. On the same note, the Mk II GT-Rs I have seen at my track have ran in the low-mid 11's. Respectable nonetheless, but just not up there with when my beautiful beast was stock. Gosh forbid I had ever ran it bone-stock w/ some drag radials. That could have netted me mid 10's at my track.

Here is a link to the mods list. This was the initial 10.0@141 pass in high humidity at 800ft. I believe the car went a best of 9.7@145 with this setup:

A heads/cam setup with the blower mods listed above is good for 800+whp and 150+ traps still using the 2300 Eaton. Now that's just insane!

The ZR1 is still the faster car everytime though.



I like how you just assumed the ZR1 had a ported blower when no one knows what mods were done to it. Talk about intimidation.
