Default change from stock LS6 intake to ported fast 90MM and NW TB how much H.P.?

I just installed my ported fast 90mm intake and Nick Williams TB. My car made 423rwhp and 376rwtrq with everything in my sig and the LS6-intake. I can really feel a difference in the midrange. Just feels like the car response alot better than before. What do you guys think the new #'s will be? Thanks

You should see a +20-30 rwhp gain with the 92/90.

That is so true.
But with his mods he should see a 20 rwhp gain.
Also a 10-15 rwtq.

Do you have any track times for your car? I was hoping to get around 440rwhp with the intake and throttle body. I just sent my converter back to PTC to get recut. Then on with the 28" tall tires and off we go. Do you guys think it's possible to get into the high 10's with what I have?

No track times for me,it's just a street prowler
Depends on your cars weight, suspension and driver mod
Good luck your car should roll.

Yeah a friend of mine installed a ported FAST and NW 90 and lost 10rwhp on the dyno, nobody can figure it out, but the car still pulls harder up top.

21 rwhp gained, was that mid and up top mainly or did she gain down low as well. Even if its peak hp, thats a good gain.

GM High tech just did this and gained 20 RWHP. Which is about avg I would say. It was a cam only car. So with heads I would say its just going to open it up even more on the top end.

What exactly is the issue with the Cheapo Typhoon ?? Are they junk or what. Seems like they would get you more then 14 rwhp.

However 14 across the board is better the 14 at peak.
