Of the three, what intake would you use As the title says, which of the following intakes would you use and why on a F1R procharged car turning 7500 rpm, at about 25 psi of boost.
1. LS6 w/ TPIS modded 90mm opening (maybe some very small porting I.E. port matching to the heads)
2. Fully Ported LS2 intake
3. PP Typhoon 92mm intake (maybe some very small porting I.E. port matching to the heads)
In any given situation the throttle body would be a ported stock LS2.
Thanks for you input.

I'd be a bit leary of using the TPIS with 25psi. You know the new snout is epoxied on there, right? I'm sure it's held on pretty good, but I wouldn't want to chance it at that boost level.

Neither of those are an option, thanks though. This is a very tight budget build and right now those will just not be a possibility.

Verdad Gallardo Well, that's what I was told when I inquired about one a couple of years ago. If it were bonded/welded in some stronger manner, it may be worth looking into. Give TPIS a call and see what they have to say.
i would save some cash and just go with the edelbrock and an elbow. its much more worth the money, been proven in numerous builds and you can always increase your power with it.
I would an am using a ls6 intake, stock tb.
ls6 intake should be good to 1000 hp without to many issues with a turbo, and stock tb as well.
If you on a budget, use a stock, and spend the money elsewhere. go sheetmetal when the time comes.

I pulled the VicJr off a car because the elbow was causing some crazy fueling situations. We put on a FAST 90 and it solved all that-although I'm still not a big fan of the FAST and FI.
On my own C5 I just run the LS6 with a ported TB and it's seen over 900 rwhp @18 psi. This through a auto to boot.
I considered the LS6 with the 90mm inlet but I'm told it's only epoxied together and not recomended for boost.

We were using the GMPP intake with the nitrous Dave elbow on OntarioVettes car. Everythime we put the car on the dyno it would go pig rich, then lean at 5000 rpm-couldn't tune it out no matter what I tried. I thought it was pumps, etc. Pulled it off and put on the FAST and bingo-I get the 11.1 AFR I command. Still haven't put it on the dyno to finish off the tune but we will shortly.
very tight budget? You aren't gonna be throwing 25psi at a 4-bolt setup setup. That means LSX or ERL blocks; I don't consider those to be budget...
