As the title states. I have a 2004 ZO6 with a P1SC-1. I have kooks long tube headers, high flow catts, B&B axle backs. Right now I am tuned on 93 pump gas. It still has the stock motor, from intake to oil pan. Has 42 lb injectors, that came with the kit. Makes 5LBs of boost now. Has the twin inter-coolers that came with the kit. I would like to do some work, to up the power. But would like to keep the heads and bottom end stock. I would like to install a blower cam, pulley change, upgrade the fuel system, injectors, and add meth injection. And I would like to stay, on 93 pump gas.

Is this possible? Can I get the HP level I would like? And still be street friendly.

If so would you guys share your engine combinations please.

650-700 RWHP on the stock bottom end is pushing it. It has been done but most people will say that the stock block should be kept at or below 600 whp for the health of the motor.

You can definitely make the power with some 60-80# injectors, secondary fuel pump, meth injection, small blower cam and a pulley. I'd also recommend ditching the dual intercoolers for a large single unit.

I would consider doing an A&A Bracket and single intercooler along with some 60 lb injectors. Then do the blower cam and pulley swap that you already mention. I would consider doing a methanol kit at the power levels you are after. My car with cam, headers, stock heads and snow meth kit made 605/530 at about 10 psi boost that was on an ls1 with stock ls1 heads. So you will need roughly 10 psi to reach the power you want.

'04 Z06, A&A V3-Si, 3.4 Pulley, Alky Control tuned with pure M1, A&A Blower cam, ZR1 TR6060/diff, full bolt on with 91 octane my car made 660 at the wheels on a couple of different dynos. Pulley down and meth the **** out of it.


I will add that my SBE **** the bed on a 180MPH pull....

Thanks for the input guys. Please keep the info coming.

I tried this...got 611 and boom!

Sitting at 670rwhp on a mustang dyno but I have AI heads / 13psi. What's the reasoning behind not wanting to touch the heads but you will install a cam? Heads will make the car more efficient and make more power with less stress (boost) on the motor.

What blower/pulley size?
What size injectors and do you know max duty cycle?
What is your fuel system?
Running methanol? What nozzle size?

Hope you don't mind me butting in bada, I have a 03Z and similar goals... more info the better. Something else that may be a little different for us vs rest of the C5 section is that we have the C6 style fuel system. If you're just going to add an external pump then I guess it will be more or less the same end result. I put in the LPE / walbro 450 in mine in prep for boost.

1500 / 2.25" pulley / stock size balancer

IIRC 60s which came stock with the ECS kit. No idea on duty cycle as I switch to an A&A secondary drive and will be spinning the blower higher.

ECS stage 1 (02 Z06)

Yes single nozzle and I would have to check, been a few years.

Thanks man. I have similar cam and AI 226cc 243 heads, wanted to pick your brain a bit. I think I may need 80lb injectors if I stay with fuel pump/tank mounted, non boost referenced FPR.

I don't mind. I am looking for all the info I can get. Before I start on the car. I already have a supercharger, kooks long tubes, high flow cats B&B axle back, 42 lbs injectors. I know, I am going to need fuel upgrade, pulley change, cam, meth, and new tune. I am looking for a good combo, before I waste money. On the wrong set up.

bada

I drive the car a lot. And I was hoping to get to my goal, with stock heads. And spend my money on a tr6060 up grade.

you can easily make your goal on stock (unported) 243 heads... the bottom end should be fine as long as the tune is spot on and you have enough octane (93+meth or e85 is even better)

definitely do your homework before diving into territory like this
another thing to consider would be ditching the cats. mine's been fine at mid-500s with high-flows, but now that i'm in the middle of adding hopefully another 100hp, i was advised to go off-road so as to not risk melting them (which clogs the exhaust, causes a LOT of backpressure, and pieces of engines to unexpectedly liberate themselves)

Great info thanks. This is the kind of info that I was looking for.

Are you in the service? I see your Location is Singapore. If so thank you for serving our country.

No, just making a living.
