Pulled out of the driveway at work behind a '99 Z28 M6 with an unrecognized quad-tip catback. Followed him out to the main road (I was going that way anyway). As I get straightened out, I'm at least two carlengths behind him; he's in the left lane, me in the right. Slighly uphilll, doing maybe 20.

I get on it as soon as I'm straight. He does likewise. I pull on him through first, second, and most of third, letting off at 90mph, at which point my back bumper is lined up with his front bumper. Slowed down, gave the thumbs-up, grinned, and continued on my way.

Five minutes later, I see him again (we took different routes to the same place). He pulls into a sandwich shop, and I follow. Talk to him a bit. He's had the car a week. No airbox lid, and he doesn't know what catback he has.

Anyway, I'm trying to figure this out. We both have LS1 M6's. I figure most catbacks are the same in terms of added power, with some trivial margin of error. Is my airbox lid really enough to let me pull three carlengths on him?

 

Good Kill. I your case, him only having the car a short while, I think your lead could be mainly contributed to user error. He probably hadnt ran the car hard through the gears as many times as you have. Although this is not to discount the fact that you have more mods than him which only made his situation worse.

Let's not forget that you have an LS6 intake while his is just an LS1. That's obviously going to help.

 

This is news to me. My LS1 doesn't have an LS1 intake? Please explain.

 

haha 01 and 02 years came with an ls6 intake manifold

 

Oh, cool. Yeah, that would help.

I knew that the factory spec horsepower went up by 5hp in '01, but I figured that they were just adding numbers to an underrated engine in order to make it look like progress.

 

It's like G.I. Joe used to say, "Knowing is half the battle".

 

LS6 intake doesn't = 3 cars though. I agree Bersaglerii with the driver error. Good kill though.

 

what does your car run in the 1/4 mile? my buddy has a 99 ls1 with exhaust and a lid, no headers though. curious as to what he would run. we are side by side w/o my juice. with it, i kill him.

thanks,

jim

 

Just noticed the cannibal comment.

I'll take my car to the track for the first time at M10 this Saturday. Then I'll let you know.

Took the GN and my father-in-law's '70 Buick GSX to the track this past weekend. 13.6@99 on the GN, running 15lbs on 93 octane and crap street tires. 2.06 60'. I wasn't launching hard enough, and didn't get enough runs to improve.

The GSX ran a 13.5@100, similar 60' time, but spinning hard through 1st and 2nd. The rear quarter panels tell a nice story. His air filter is starving the 462ci motor at high RPM -- not enough hood clearance for the right filter. With tires and more air, I think he'll get pretty deep into the 12's.
