Tune, Pulley, Long Tube Headers

[Blackdevil77]

I'm really really sorry if this was beaten to death, and I'm sure it has since this car has been out for quite some time now, but I can't help but go back and forth in my mind. I've been set on a C7 Corvette Stingray for quite some time now, but I don't want to go past bolt-ons. So if I were to get a C7, all I would do is intake, long tubes, exhaust and tune.

I was just wondering, a ZL1 with a tune, long tube headers, exhaust, intake and pulley are putting down what kind of power? And most importantly, what are cars modded like this running in the 1/4 mile? Would a ZL1 Camaro with said bolt ons out run a C7 Corvette Stingray with the bolt ons I mentioned above? A C7 with headers, intake and tune are running in the mid 11 second range around 120-122 mph.

The fastest bolt on ZL1's are doing 10.4 around 128 mph. The ZL1 will make a lot more power with limited mods but it is a big jump heavier. You can easily get over 600 hp to the tires with a supercharger already on the car. If drag racing is all you are looking at, the ZL1 is the winner.

Is there a "fast list" with times and mods listed? Drag racing isn't all I'm looking at, but I won't be going to a road course or anything. Just drag strip visits, but I have some fun on twisty local roads, which I'm sure the ZL1 is very good with.

So what you are basically saying is with simple bolt ons, this car will trap around 128 mph!!!????

Also, I remember reading that the rev limiter, which is set to 6200 rpms, can be raised and the power doesn't drop off at all. It actually goes up, and it is safe to rev it to 6600 rpms. I may be coming over to the ZL1 side if this is all true. Not much to be had out of the C7 from bolt ons. The factory exhaust and intake aren't very restrictive, and all that combined with a tune will net you in the 40-45 extra rwhp area.

I'm trapping 122 with just a 8.6 inch pulley. With no tune.

Wow, I didn't think you could run a pulley without a tune???

There is a lot of untapped potential in a ZL1. Here is the fast list, scroll through the first post and the ZL1's are catagory 9,10,11,14.

I've got a little crazy with my car but I figured right from the start that if I bought a used ZL1 and put the $20 K I saved over a new C7 in mods no stock C7 would touch it at any racing venue.... I have not seen many C7s yet and have never been passed by one.

600-630hp depending on recipe.

you will have to add injectors and possilby hx to the list but guys with autos are runing 10.6-10.8 with bolt ons.

manuals are more like 10.8-11.0 ish.

all on the right tire.

then if you get into porting and cam litterally people go all the way into the high 9's in the auto's.

the C7 has a more updated interior by a long shot though and a removable top but no back seat.

Thanks for the link! It's looking like stock for stock, the C7 ever so slightly edges out the ZL1. Full bolt ons to full bolt ons, they switch, with the ZL1 beating out the C7. I absolutely DO NOT want to go into the motor on my next car, and I toyed with the idea of putting a supercharger on the C7, but knowing that the ZL1 comes with one, and the engine is more set up for a supercharger, it just gives me added piece of mind. The high CR in the new LT1 scares me a bit with supercharging.

Is that 600-630 to the wheels or crank?

I've never owned a FI car. Is changing the fuel injectors a big deal? Does it require a lot of tuning, or is it fairly simple for a shop to do? Same question with the heat exchanger, is it a simple modification?

If I can trap 125-128 mph in the 1/4 with Long tubes, exhaust, pulley, intake and tune, I'll be happy.

Sounds like you should be waiting for the C7 Z06 and have a factory supercharged beast Corvette!

If I had my choice, I would have both since they are totally different cars. Though I did tell my wife eventaully we will have a C7 Z06 sitting next to our ZL1 in the garage!

thats wheels with the right combo. an auto might be 580-600ish.

yeah injectors are simple IMO id850's are spendy about $800. HX is easy IMO as well but the nose has to come off. not a huge deal they are $500-800.

there are guys trapping 130 with larger pullies. ie 2.4 uppper or 10" lower.

you can always do 8.6 low 2.55 upper as well.

seems like the ulitimate easy labor bolt on combo would be like:

headers 1 7/8 or 2", 8.6 lower, 2.55 upper, ported snout, 102mm tb, id850's, hx or chiller, CAI, tune.

~5k in parts

all of that dialed in should net 10 second power with 127-131mph top speed once ironed out.

basically if you buy the car at employee price for high 50k-low60k you would have have a car that rolls witht he best of them. traction will be a puzzel to solve and waranty is toast though.

I have seen a setup like this dyno at ~640whp recently if memory serves.

Oh, believe me… if there is some chance, somehow, someway I can afford the C7 Z06, I'd be going that route without thinking twice. It all depends on cost, and I'm 90% sure I won't be able to afford one, unfortunately. Low 60's is my absolute max right now, that car will be starting AT LEAST in the mid 70's, according to Tadge's statement.

That would be absolutely fine with me. Either way, the warranty would be toast, whether it be a C7 with bolt-ons, or the ZL1.

Factory boost is 9 psi, right? What would the boost go up to with, let's say the 2.55 upper pulley and 8.6 lower pulley? What amount of boost would be considered "safe?" I'm thinking maybe 14 lbs on stock internals at most???

I have exactly what you're asking with an M6 and numbers are in sig

Nice! Have you tracked the car???? 615 rwhp and 623 rwtq is really healthy, I'd say

Not yet. This weekend will be my first run with this setup. Waiting on some drag radials...
