Did you read what I wrote?? I said "LS1". What is an "LS1"? The first of the Gen III architecture rated at 305-350 hp, depending on application and year.

2002-2004 Z06, FYI is an LS6. And where did I comment on the weight of any engines in this thread?

About 8 months ago, Daniel, in an earlier, rather annoying thread, went on and on about how after all the money he's spent, after all the work and parts he's added, his car still doesn't feel as fast as some C5 LS1 that he had access too. He asked the forum, "WHAT'S HOLDING ME BACK?"

The overwhelmingly popular response was that:
"You don't know how your car is performing (SOTP don't mean squat), so go measure it's performance; dyno or track" He didn't like that input and continued to compare the SOTP of his car vs. his dad's C5 LS1.

NOw he's dyno'ed it. How does it ACTUALLY compare w/that C5 LS1?

You see where I was going with that? Never said anything about LS6's.

My experience with the Miniram combo is that is does feel sluggish driving on the street. It doesn't have that Torquey feel of the TPI.

But, on the Track & the Dyno, it will rock.

That raises my next question... Can I hit 11.99 seconds with this?

Not trying to offend you, I consider a Z06 an ls1 designed engine. I was also commenting that a since a Z06 is lighter then a C4 with the same power it should be faster. That was my comment to your comment.

Maybe but I doubt it. The 60 ft required to run 11.99 with that level of power is too low. My guess is mid to low 12's with good traction and 60 ft's in the 1.6's.

I am gonna have to agree , low 12's.

For referance, my Miniram combo, the first few times out to the track went 12.1 (with my old 12" convertor).
60' times were in the 1.8 range.

Only one way to find out, but that would require taking it to a track.

A 340 whp car CAN go into the 11's.

Copy. Your comment kind of came out of no where; you quoted me, but I said nothing of Z06's or LS6's. You may consider them to be the same but they are not. Hence the different name and hp/tq rating.

Nice power levels!

The tune looks good with a solid AFR across the board, but I think you might have more in it just leaning it out a bit; maybe to 13:1 or so, NA that is OK. It is a bit rich, not real rich, just a bit. My 85 picked up a few on the dyno going to 13:1 or so.

BTW;

You will have your hands full trying to get in the 11's with your car, trust me. Especially if you have never been on the track.

I would guess with little experience your 60 foot times will be 2.0 at best to 2.3 or so trying to launch your stick shift car. It's a trial and error approach. With that kind of 60 foot times you are talking mid to high 12's and if you really get silly on the launch you could end up in 13's. It happens.

I would guess your MPH at about 111-112.

But only one way to find out and get experience- take it to the track and let us know with REAL WORLD NUMBERS like you did above!

Congratulations on your car's dyno man. LONG time coming this was.

You might have a little more in it, but I wouldn't fiddle with it further at this point. Great job on the tune.

NICE JOB daniel!!! You were all worried and stuff. Man that is a wicked flat curve and that miniram pulls like a bitch to 6500.

Also, I seem to recall you having tuning woes. I bet if you slapped that on a dyno tune you'd get another 20hp+ out of it!


Oh ya, and about tracking it... worry about your 60' time THEN worry about 11's. My car is retarded quick, first time to the track I dont think I got better than a 2.6 60'... poor launching, TERRIBLE track prep, and 25 year old slippery rubber.
