i was wondering if you guys knew were i could bet a blower for tbi, i know its probably out of the question but something like a 6-71 with duel tbi ports would be awsome. i currently have a tpi computer so running 2 tbi's would not be a problem

90 RS 305 tbi, 4 3/4" cowl Hood, Edelbrock TES headers, Flowmaster exhaust, Crane roller cam, comp roller rockers, vortec heads/intake, ported tbi, w/new injectors, MSD probillet Distributer/ coil, 1 inch tbi spacer, air foil, 14x4 k&n flat base air cleaner, Rebuilt 700r4 w/ B&M shift kit, B&M Megashifter, 3.23 posi, 2 12 RF's with mtx amp, top of line alpine cd player, soon to have 90-91 gfx, z-28 wing, new paintjob, rims, and all new lowered suspension.

 

Actually a TPI motor can't even run 2 TBI injectors. 8 peak and hold injectors on a TPI system are 2.4ohm load, TBI injectors load is 1.2! The only TPI ecm that can handle the extra load of running a TBI system (2 injectors) is the quad 4 or syclone/typhoon ecms. There is a bunch of this talk over at the diy_eprom board. I've been trying to figure a way myself but it just won't work unless you're good at adding on injector drivers (not me).
As for a blower...shane b did it a long time ago but I think he had problems so he went to a carb. The only system right now that could handle dual TBIs and a blower would be the holley pro-jection line of efi. They seem to have cornered the market (according to most experts). They designed the system for GM but GM gave them the shaft and let Rot. make the systems. The only part I don't like with the holley systems is the injectors. They were going to go to better ones but that fell through . They're also pretty darn expensive. If you want to go to a blower I think your best bet would be to go with a carb until you can afford to go to some sort of DFI. GM ecms are great for NA engines but unless your engine came with a turbo....they are a PITA to tune, carb is much easier.
If you're set on TBI on a blower then talk to JoBy, he's the guy that invented the winaldl software for our cars. He has a blown crossfire vette which is almost the same thing. TBI, blower, 160 baud data rate, switching o2 sensor etc. I'm sure he would be of some help.

 

really i figuered that because the tpi had 8 injectors that it could control 4 tbi's thanks

Just use a TBI with 2-bar MAP sensor and tune woith the WINALDL program??? Any old blower, like the 144 weiands, smaller B&M, etc???
