Nice gain! Stock fast or ported? Would love to see a graph. I have one that I'm going to put on shortly.

+1 here as well. I also would like to know if this is a stock fast or ported. Judgeing by your numbers I would also venture to say your car is a m6, with headers, exahust, intake and a tune as well. I need to get one of these on my Ls2 gto.

92mm fast intake

The intake was non ported stock out of the box!!!!!! . needless to say I was happy with the results. other mods are honker cold air intake, slp 85mm mass air ported 90mm tb, 1 7/8 lngtubes headers withx pipe /cats B&B catback. stock cam & heads still making good hp.

386 rwhp to 410 rwhp air to fuel ratio at 12.8 timing set at 26 to 28 degrees.

According to some literature that I was reading sometime ago the stock Ls2 intake has a lot of leak by and was poorly manufactured. GM switched it's manufacturing process with the LS3 intake to correct the issue.

Nice gains for a non ported fast! It's not surprising though as GM would want to hold back the power of the LS2 knowing the LS3 was coming in a few years.

Hello,
Excellent gains for the mods. Are you going to add a cam at a later date?

I'll more than likely go with a cam with a 228/232 588 to 591 lift. I don't want to go any larger than that . As for the heads I am not sure,

2500+ for trick flows will hurt me deep, I will continue to do my home work, I only want to shell out 1500 at the most for heads.

Great gains with the intake! The bolt-on LS2 and LS3 cars are getting scary fast!

There's another thread here about the Trickflow heads right out of the box that made great power and went for around $1700.

I don't understand this. You are driving a $50k car, have put several thousand in bolt on's on your car and you are wanting to cheap out on the single most important piece of the HP equation. I understand everyone has a budget and when you run out of money, you run out, but I would have looked for other places to save a little coin if it were me.

I am not saying that you have to spend mega money on aftermarket castings, I am just saying to think about the context of what you are doing.
