My twin supercharged tbi 350 miata build

I'm a little late to the party, but I agree. The slight difference in speed will only result in one blower providing slightly more air than the other. The PSI will be even since they're plumbed together (I assume). My concern is whether the V belt would be able to provide enough horsepower to run the blower and whether or not the alternator would slip with the original setup.

sorry i didn't tell you guys.
I have it all worked out to where a single belt will be used all driven by the crank. Problem fixed :D

I got rid of the passenger side tensioner, replaced with single idler, added another idler right below alternator and now it's capable of running just 1 belt. :]

I know its a bit of a dead thread, but I'd love to know how the intake piping is routed...

[Tylerz281500]

i was hoping it wasnt dead

[Shawn1989]

Dead thread. PAH!

you got another thing comin.

Sure!
I like the idea of a Dynamic EFI EBL system: http://www.dynamicefi.com/EBL_Flash.php

For a boosted TBI engine, the EBL System is a very good option.

Sooooo out of my price range lol

need pics! wanna make me the mounts!? =)

Sooooo out of my price range lol

Maybe other members can offer a budget suggestion for a TBI boost computer?

How well would this work?

i have a wideband and i can get the aeromotive regulator. Intercooler is about to be ordered.

I think its worth sharing one of the comments form the link above:

"5/20/01 (If you want real control) Accel DFI Fuel-Spark ECM. I have since installed this computer and was able to delete the FMU entirely and up the injectors to 50# and install a 2bar MAP sensor which allows the computer to see boost. Now I have complete control over the fuel map. The fuel pressure stays at a constant 14 PSI and the computer controls additional fuel under boost through the injector pulse. I was also able to ad an air temp sensor. "

I still favor the Dynamic EFI system vs. Accel DFI Fuel-Spark ECM for "REAL CONTROL".

Does a free tune come with it ;)

Likely not.

Once you figure out what computer you want to use, the next decision is the bypass valve control.

"Bypass valve: I should also mention the Bypass valve. The bypass valve is a release which vents off pressure in a rapid de-acceleration situation. When the Supercharger is producing boost and you abruptly let off the gas, closing the throttle plates, the boost has nowhere to go - kind of hard on everything. The Bypass helps relieve this and also helps smooth out your idle. Under idle or normal driving (vacuum) the valve is open. When it sees a boost signal it closes. This is also helpful in building up boost quicker. I have tried a standard Bosch 1" and a Vortech Race Bypass Valve."

I have a bosch one from a saab/audi for each blower. When it hits boost; it closes

Which one would i purchase? The $430 or $380?
