you can pick up ported lower IM for $179 at road race motorsports....you also need 60mm TB, because your 55mm is just too small for it...with that IM stock TB becomes restriction (i can get you one for good price)

somewhere around 115 ... which is not much comparing to RRM 60mm TB for $300

YOu should at least port match your Lower IM ---port point where it meets with upper IM to the size of your IM gasket, that way you will have smother air movement and no vortex

the peak whp gain was only like 8 or something... but the max whp gain elsewhere in the rpm band was like 24 (undoubtedly after 5500 rpms when the stock manifold falls on it's face)

Oh yea that sounds good, Ill be in touch with you on that. What about a bigger MAF? Any where to get one of those?

Maf is not really restrictive comparing to other things ...if you will go 70mm TB and boost then you can do your MAF.

With cams, UP IM and TB, the next thing to improve is lower IM (if you would want a bit more power)

And remember hp and whp are different things, on N/A this IM gain 15 whp if you have lower IM and TB, with cams it will gain a bit more.....

I have MY upper and lower IM on their way and once there installed i was going for the BBTB is next. You said you could get one at a good price for him, Is that for everyone or just for him?

yes...these numbers are true if you have cams in addition to IM...my falls on its face after 5.9k goes down to 180whp at 6.5k....with IM and cams 6.5k is where you have peak and big gain of up to 24 hp...but usually in range of 20whp

MAF has problems with high boost air flow.

It was ported by machine shop and i just have to do finishing touches ... comes with new and bigger butterfly plate (thing on inside) ...the rod that holds butterfly plate is stock with expanded opening to fit new plate (that my part of the job)...on outside everything looks like stock

Stage 4 IMs are the best NA mod, hands down my favorite. Kinda funny to see a few new guys see or learn about it for the first time lol.

yea while it's off jproph, you might want to measure the inlet plate. If it was 60mm i'd consider sending it to TC and have a new flange welded in that is 70mm like the new ones have. Just an fyi

YEa this one is a 60mm by the look of it, but I will be looking at the stealth turbo next year and Ill get the 70mm then I guess, I wont be going ove a 60mm TB this year anyway. So it should serve its purpose.
