ZL1 to a 1LE?

Here ya go

Wow, the max speed and avg speed are barely any different, probably can't even tell driving.

I guess the whole lap is only couple second difference... wow.

The differences would get much much smaller for a 1LE with cheap Z/28 aero upgrades, 305/30/19 sticky tires, and ZL1 (or similar) brakes.

So basically, the ZL1 supercharged engine is actually a minor upgrade in some ways compared to the 1LE?

At Www.grattanraceway.com a stock ZL1 driven by a motortrend racecar driver ran 132mph on the straight. I ran 124mph when stock, but that was because I feared the stopping power of the factory 4 pistons. After switching to the 6 pistons V brakes I was able to hit 128mph with the same HP.

2.27 difference in lap times,

Like others said bigger brakes would trim that number up a little, then CAI and Exhaust would trim it down some more. Stickier tire dead even....Maybe

He just wants to prove the ZL is faster... It is! The Milford lap times are most likely hero laps too. While we can speculate this mod or that mod to favor the 1LE it doesn't mean much when you do the same thing to the ZL. What we can say though, is the 1LE does a hell of a lot more with less. So that right there is the perception of being better. Give two guys 60k, one buys a ZL the other a 1LE with the remainder spent on mods... That's when the 1LE will smoke a ZL! And that's why its a better track car.

There are things that are very hard to remedy with mods, like substantial weight of ZL1's engine and drivetrain. 1LE is almost identical to Z/28 in weight, and possibly even better in weight distribution. Z/28 suspension, wheels, and aero can make 1LE a great competitor for a very affordable price. Even stock to stock, you can see 1LE braking deeper and corner harder in many sectors.

I have run 100's and 100's of laps at laguna in my 1le with a best of 1:43xx I have run 98 laps in a ZL1, best I could do was 1:45xx because the extra speed in the straights caused earlier braking, in my case. The biggest difference is the handling to me as the 1LE has excellent feedback in any situation, I could never tell what the ZL1 was about to do. Just my $.02....

No.
That simple.

Its been debated on here a lot. By the time you do enough mods to catch a ZL1 you've basically built a ZL1 except its now a modded car not worth much. It sounds good on paper until the Z shows up with a CAI (40hp bolt on) and few minor engine mods (pulley, headers and a tune) lowers the car 1" and comes outs with better tires on. You all keep talking about modding the he!l out of a 1LE but keeping the Z bone stock. Most guys who will take the time to go to the track will also tweak the car, including the ZL1.

Just accept you have a really great car for the value. But its never going to be a ZL1 the same as I'm never going to catch a new Z06 on the road course.

I'm sorry, but it's not that simple. Z/28 is better than 1LE in every way; ZL1 isn't, and some of the issues are next to impossible to fix with a mod.

Yeah, it really is not that simple. The mod talk was more driven by a dollar for dollar perspective. It was to highlight that for less money than a ZL1 you can make a 1LE faster. This is obviously because the 1LE is somewhat stripped down in comparo, and that is due to its track focused design. The fact the 1LE package can be had for $3500 is really what makes this possible. I dont think anyone would ever think a modded 1LE is BETTER than a ZL1(would be foolish), but it is clear it can be made faster for less money and that is because you dont get things like mag ride etc that drive up cost and not so much performance.

I think this post brings up a clear point. Better and Faster are not necessarily the same thing. If you spent the lets say $20K difference between the two cars on go fast parts alone, I do believe you can make the 1LE faster on most road courses than a ZL1. I say most because I think if you get into a course the Nurburgring, the long straights are going to give a huge advantage to the ZL1's massive power. I know most are going to say that if you have $20K to spend then you could match the ZL1 power, and my response is that if you do, you will be adding weight and other disadvantages issues that the ZL1 has. Back to the Better vs. Faster, as mentioned in the quoted post, your still not going to have a mag ride system and some of teh other electronics on the modded 1LE, so unless the ability to go faster is the only criteria for better, I think the ZL1 is still gong to be "better".

Disagree. I like the ZL1, but even before the 1LE was released I knew it was not for me and cost was not the determining factor. It was the weight. I was (gulp) planning on purchasing a Boss302 for track use, and then the 1LE became reality.

Weight is flat out the enemy of any track car no matter the HP. It eats tires, heats up brakes and can remove the fun factor on track. I have seen more ZL1 front tires chewed up than any other car at the track. Car are getting heavier and heavier, but I refuse to track anything over 4000lbs and truthfully the Camaro is pushing my mental line in the sand as it sits.

You don't need to "mod the hell" out of a 1LE to achieve results: CTS-V brakes ($1200) smaller wheels and tires, ($3000) CAI, LTs, tune ($2000) add any bushing , sway bars etc you want to add. ($1000??) Add $7200 (or even $10K) to the price of a 1LE and you can be well under $50k. Mine was $35K with discounts and I am still under $40K by selling the stock bits I have upgraded and it sits at about 3800lbs

You stated "But its never going to be a ZL1" My response is why would I want it to be a ZL1 for my fun track day car? I have respect for the ZL1 and if I wantd a boulevard monster or drag car I would have purchased the ZL1, but that was not my intent.
