interesting. how much boost did the pulley give and what kind of tune is on the ECM. more curious as to the actual dyno graph on it.

If you saw the previous post with the dyno graphs it looked like in stock form it was making a max of 8psi of boost. Add the 3 - 4psi of boost per what the article said in Hot Rod and you would have approximately 11 - 12psi of boost. Nice runs LPE!

The cold air intake looks like it fits perfect and probably makes great power with this alone.

Now we're getting somewhere. Simple mods really made a great time.

Wait. Was proper break-in followed?

Ahhhhhh, running VP109 fuel. Even so, for just a pulley change, tune and CAI thats pretty damn impressive. Not just the times but the trap speed..............

I got my wish. lol. so a 2.0 60' would net around an 11.8. so yea.

That was sweet, but if your going to mod a ZL1 to go fast straight, would your money be better spent on a SS?

Yes its now broken in;)

Very nice if that is really 3-4 more psi and for the mods .. .. cheap mods and big gains :)

Sorry if I missed them in another post, but what were the baseline times?

they are suspect but 12.5 @ 116

that would be Henessey times not LPE. the base line LPE did was dyno charts and it is in another thread.

This vehicle was not baseline tested at the track.

ah yes my mistake.

So I have on order a Yellow ZL1 in Michigan, that may get pushed back to a '13! Any info on if I can get some of these mods on mine before I bring her home?? And cost?? Sorry a little new at this! I had an 02 SS with the Stage 2 SLP Package, but any info on how to contact Lingenfelter would be greatly appreciated! Thanks!

I love it, easy 10's with that mph :chevy:

um go to their website and call them? google, email?

Now thats Impressive!!

Impressive!!! Run was made with vp109 fuel or 93octane? Any videos?

VP109

Check the dyno chart

If getting power is that easy why did GM, just not do these things from the start?? Or why don't the 2013s come with a pully change and better cold air unit so you don't have to loose the warranty on a 60K car??

Thanks!! Just looked them up!! I just may have to have them take a good look at mine before I drive/haul it home!!

That's awesome! Can't wait to see it break into the 10's. Car is definitely capable! Good luck, happy modding, and safe racing!

Nice.

NICE!!!

These runs were done on Apr 5th?

I am surprised that the first we hear of it is 9 days later.

I thought the internet was faster too!

Hot Rod did the article and it's their choice as to when it is published not outs.

Graham.

IT's called reliability. GM wants your cars to last as long as possible. LPE and tuners want your cars to perform consistently but don't expect them to last 150k miles.

So race gas, race tires, tune, pulley, intake, ported, thermostat oh and the warranty is now gone. Still can't break 10second though, still pretty disappointing. Think what the ZL1 is showing is that the SS is a great value, slap 30k worth of mods (price difference between the 2) in an SS and you got something putting out 9s/ high 8s. Though that magnetic ride is quite nice and maybe the aerodynamics aren't BS, though is it really worth 30k to have the zl1 as a starting point to mod rather than the SS.

I wasn't pointing any fingers. I just figured this would have leaked out sooner.

I like what I see. 10s should be easy with that mph. Are the 60' ft's limited by the tire or testing? As well will a 17inch rim fit on the back with a slick and can you hit the car any harder? I may have missed it manual or auto?

If you dont mind me asking did you get any air temp data?

Sorry for all the questions more interested in data than the actual run, but the run is nice and shows that once time is given the zl1 will be able to kill at the strip and the road course with out affecting each other.

Baseline time would have been nice.

LOL it's on the verge of 10's. and it could have been a couple of things keeping it out that day. track prep only at the starting line, track maybe was cold and the temp could have been also. Seems like your expectations are a little high.

If you only care about going in a straight line (which sounds like that's all you do). then modify your SS swap out the rear for a SRA and go to town.

A new car is out and they are scratching the surface. On a good day with a good track that car would have seen 10's easy.

As well so many people keep pointing out that their ss will keep up for less, thats great but would it be able to keep up on the road course as well. Normally everything is a compromise from one to the other. the ZL1 is starting to show that it will be able to hang pretty good at both tracks with a little work and not upsetting the cars suspension or much of anything else.

Also people talk about the warranty, everything I have seen on this car can be switched back to stock pretty easy unless GM is actually watching how many times the tune is changed. I had heard rumors of this but never got anything solid on it.

;)
Launch was a little tricky to maintain consistently, da. Was 1800 ft temp mid 60s iat 2 at the end of the run was 160 f
Better tires will help greatly, car transfers pretty well, overall we'repretty pleased, but not satisfied ;)

what you're saying is you need more seat time? lol. good stuff.

11:00s @ 130-mph with nothing more than a Cold Air Kit, Smaller SC Pulley, Tune, Tires, and some race fuel :). The mph should be good for 10:70s.

Now i feel MUCH better, after having spent the better part of the morning reading about the disappointing times Hennessy put up on a stock ZL1 at the track.
