Default need 70 more HP

I just picked up a 03 Z06 and I need some advice on how to gain at least 70 HP without tearing into the motor. I live in Denver and see that's about what I loose in HP because of the elevation here.
I also race a Hayabusa drag bike and I'm use to 8 second runs. Not that it will be used much for that I would at least like to achieve the 350 or so RWHP most of you are probably getting and mid 12 quarters. Dont want to show up and run 14's if you know what I mean.
I run nitrous on my bike but it is tough on an engine and dont want to put it on such a nice car. I see these hand held tuner adds claiming 35 HP increases do they actually help that much? Cold air kits?
Different throttle bodies? Exhaust system? What works best for a quick bolt on fix?

All the right bolt ons will get you close, but tuning will be required to extract and optimize at your altitude.

Here's a list that will become familiar as this thread continues..
Headers and high flow cats
Cold Air intake
Throttle body
Pulley
Electric Water Pump
Cat Back

Give me a call on Monday and I will work out a
package price for you.

Happy New Year,

Shawn

Easiest way is to re-pressurize the engine with a blower or turbo, but obviously that's pretty pricey. I'd add a Vararam and a tune to start with and see how it feels from there. The Vararam will slightly pressurize the intake tract at speed, so at least it's a step in the right direction. The tune will hopefully correct other parameters for the altitude. Good luck!

You can "optimize" what you've got, but there's nothing but a blower or nitrous that will give you back that 18% or so of oxygen that you left behind when you moved to Denver.

More Performance, Inc. www.moreperformanceinc.com, has a number of 2002-2004, including mine putting down 410-418 rwhp with the following:

Cam and valve spring upgrade.

Kooks long tube headers, 1 3/4.

Pipe with high flow cats

Vararam cold air kit.

Cars go from 340 rwhp to 415-418 rwhp.
Dyno/tune using LS1 Edit.

Got to be tuned, right way on a chasis dyno.

Look at it this way. Everybody else in Denver faces the same problem. So you're in the same boat as the rest. But if you're insistent on changes call 3R Automotive at 303-781-0774. They have quite a set-up and are into racing. They installed the K&N Aircharger for me and di good work. They're on 3701 S. Klamath St in Englewood.

I don't think you can add 70hp just with bolt ons. A cam and bolt ons, sure, but not just bolt ons like headers, intake, exhaust, etc.

:werd:

i think most of us with bolt-ons and a tune dyno at about 390rwhp (i was at 393/383 with headers, xpipe, catback, intake, and tune)........a throttle body and electric pulley might get you over the hump, but the way i see it is that those are expensive and not worth the price to go from 390 to 400rwhp, just so you can say you have 400+rwhp which is about 470 at the crank.........instead of spending 300 for the throttle body and another 300 for the pulley, i would just put that money into a CAM

High altitude? Go with a magnuson supercharger for 8 grand installed with painted hood...

The bolt ons won't get you where you want to go...IMHO

I am in Colorado springs, Z06's run about 13.4-13.6 at PMI in Pueblo. Mine ran a 13.2 @ 107MPH on street tires easy launch.

I then did headers, intake, GHL exhaust, throttle body and Vortech SC my best so far has been a 12.0 at 117.5MPH.

I think if you did the new AFR heads, a nice cam, headers, intake and exhaust you would be adding around 100+HP to your car. Also get a nice tune on the car to pick up the few extra ponies hiding.

Most of the Z06's that I have seen at Bandimere are running low 14's/high 13's. I Installed a magnuson on my Dads Z06 before I started working here and it went from a 13.9 to a 12.4. The car has longtubes and 4:10's as well. Thats with 2.0 60's. There is alot more in the car. This spring i am going to throw a smaller pulley and thicker head gaskets. Possibly a cam as well. I would like to see a 11.7 out of it. Kaley

Thats what I was thinking was high 13 or 14's. After racing the bike out there on test and tune I saw car after car that are suppose to be fast barely make into the 14's. Part of that is the driver the other part is the altitude. Need to decide whether to put on a supercharger and have some fun or just leave it stock and still have fun up in the canyons. The bikes we race are so fast compared to any car short of an all out dragster it seems a little boring. Guess I'm spoiled.

Is a cam out of the question as i see you don't want to go into the engine. A CAM, plus headers and basic bolt on like air intake will get you your 70HP easily. Otherwise, must supercharge or go with a nice safe lil 100 shot of N20 for those moments when you need an edge!!

Kaley,

I havent seen any Z06's running 14's, but then again that is down at PMI, I think Bandi is a little bit higher altitude, but the track is a lot nicer at Bandi.

I think I will just add some sort of air cleaner improvement and maybe a tune and leave it at that. Unless I turn into an all out pro street drag car it aint even gonna come close to a stock Busa mush less a nitrous bikes with about 250 HP.
Now whats the best air cleaner set up and tuner box?
Which one can be easily removed and put back to stock?
