I talked with several people and they shot me down recently when I told them my goal of 500WHP on the following setup using 91 Octane my stock lowend.

Is it realistic?
Should I stay with the stock HG?

(1) Ported IP Manifold
(2) Asura 3" Exhaust No Cat atomspheric dump
(3) Fully Ported Head w/ New Valves and Springs
(4) Ported Intake Manifold
(4) 5965 Ball Bearing Turbo
(5) 2MM HG
(6) 1000 T1 Injectors
(7) Walbro 255LPH Pump
(8) AEM 1052-U w/ 4 Pyrometers, IC Pipe Mounted Air Temp, Boost Controller

Here is the current build

If you say No then, I only want 400-450 for normal driving and would like to have a scramble button for the rest, should I go tubular or just throw in some meth?

 

I made 505, it's surely possible

 

You went 2mm I thought you were doing something else, not sure that turbo is going to take you to 500hp.

 

I know I have seen your post many times before but what is your setup?

 

I was planning on using the SCE copper with O-Ring, but Mase, Asura, Tony (T1) and everyone but Inline has told me that they are unhappy with the results of the lowered compression cars. From what I can tell this is primarily due to the high valve overlap with the stock cams which does not allow for optimal cylinder evacuation which is amplified by the decrease in compression ratio. So if I can find a reliable cam I would buy it and stick with what I have. Or you can use a equal length tubular that has less restriction thus better cylinder evacuation. Or go meth and cool the gases that do remain.

So what should I do?

 

Seen over 500 on a Log manifold but that was with 9.0:1 CR pistons on a sleeved block.

Can't say that it was reliable though.

 

Why would you go that high on a log? With such a potent setup it seems natural to put a manifold that doesn't limit the rest of the setup.
Its like drinking fast with a straw. You might do it fast if you try hard enough, but its much easier without the limitation of the straw.

 

one guy on here just hit 478whp on 91 octane, stock motor, full-race kit. the IP log manifold kit can hit 500whp but you'll need more boost to do it than a tubular manifold kit. the extra boost required to hit the 500whp mark on the log manifold and the fact that you're trying to do it on 91 octane will probably keep you from hitting 500whp, that's my guess anyway. I'd say if the Full-Race kit got 478whp on 91 octane, stock motor, you'd get stuck a little under that, maybe 450whp. the head gasket lowering the compression may help you run more boost but at the same time you'll lose a little power from dropping the compression.

pump gas, stock motor, and 500whp is a tough combo. you don't see a ton of guys doing it and the few that do are on 93 octane and tubular manifold kits. that's the goal I have with my kit but I'm trying to hit 500whp on 93 octane and a tubular manifold setup.

 

Why did you choose the cometic 2m over the ILP 3mm? I have been debating the same thing. I think I am more confussed now than ever.

I was thinking doing stock compression 12psi maybe with meth
2mm 14-15psi no clock
3mm 16-17 psi clock cam gear

Based on what l learned the logs produce more heat thus more need to us the HG.

 

I made 515 with a 3mm HG on 18 psi
