Why don't u check for vacuum between ur tb and blower? Urs would be one of the best examples as u have already reduced most restrictions (4" tubing, no Maf, etc) plus u runs 11's. If u have no vacuuum, then kind of pointless to do swap. If u do, then obviously more to be gained. J-tubes can always be ported a little ;-)

 

I gained 30 rwhp going from a 78 to a 90mm TB. I think a little more than .2 in the 1/4.

 

Wow that is a good gain! Does anyone know if the LPE 100MM MAF would be too much for a truck with my setup? With of course going to a 90MM j-tube and doing the 4" piping to it along with a 90MM TB. Been looking for 90MM maf's but can't seem to find anything for my application yet

 

I think you can use the newer, cartridge style MAF... Without having to buy the 100 mm housing.

 

Do the cartridge style mafs work with the older 99-02 pcms?

 

I don't know for sure, but I doubt it.

 

Here's a couple pics of the intake pipe I made today.

 

Was that with the stock maf and magnacharger tube? Nice gain btw!!!


Very nice, very nice! Interested in yours gains from this. Planning any track events in the near future?

 

That turned out nice!

 

Yeah that did come out very nice. Congrats on the great work man!
