how much boost?

[MightyMouse5310]

I have a crazy idea for a small amount of forced induction. on that note, will the stock car hold even 2 psi of boost without tripping out or will it simply not tollerate any boost numbers without a black box. If i got a MS or a safc to "control" fuel curves with the works could it hold 2 psi without the black box?

SAFC can't control fuel the way your thinking, so scrap that Idea right now.

The map sensor has a voltage reading of 1-5volts, and when it senses positive pressure ie boost, it goes over that limit causing the ecu to "trip". Your best bet is to talk to paul on here and find out how to get a black box from him, as he's making quality ones lately. He's the moderator on here.

So whats your idea for just 2psi of boost?

This is another area where just throwing around PSI figures is about as useful as tits on a shovel. 2psi at what CFM? Funnel the air from a $10 desk fan through a straw properly and you might see 10psi or more, but when your engine is already flowing air in the hundreds of CFM, it's a moot point.

People, boost and PSI, as we use the terms in this community, refer to how far above atmospheric one is able to pressurize the incoming air charge. A bilge fan or leaf blower (god forbid) isn't going to be able to increase the pressure of the intake charge. Boost is not measured as pressure at the outlet of whatever is pushing the air, but at the intake manifold. Drop a garden hose in a ricer and look how much faster the river flows. Get the idea?

Unless you specify what turbo you're considering (and "stage 2" or "T3/T4" doesn't count), we're all just sitting here jerking off. Once you understand what details are needed to intelligently discuss the subject (boost pressure), you will find that not only do you get better replies, but you keep yourself from looking like a complete stroke.

This "2psi" comment really scares me. It's got "waste of time" written all over it.

granted this idea was a crazy one, but back in the day my friends and I put a shop vac fan on his p.o.s. 89 chevy 2.8 v6 truck to see if we could make it "boosted" and it actually worked...as far as we could tell. the truck wouldn't idle normally so we couldn't run it idling, but when you shoved it to the floor and turned the fan on the truck actually went somewhere...I only figured the fan "boosted" 2 psi or less, but it worked for the most part...granted that's a whole different thing, but it did work there. it also worked on a 91 mustang with the four cylinder in it.

Pseudo-mods... why not just steer clear of gimmicks like these lest you want a ruined engine? With a 96 you may, or may not hit fuel cut, but you'll definitely run lean.

 

[MightyMouse5310]

couldn't a fuel controller fix the lean mix with a wot switch...like get a controller that has low throttle and hi throttle settings and just have a switch for wot to engage the motor?

 

[VelocitàPaola]

Nope... no way to add fuel electronically without a standalone of some type. An FCD can prevent fuel cut (that's what Rand was talking about that I make), but to prevent a lean condition you'll need a standalone (which is a waste of money for something like this, IMO) or an FMU.

Don't the sell some kind of electric "supercharger" that is some sorry excuse for a fan/leafblower in the back of magazines and on ebay. That is what this reminds me of.

Man experimentation is good, but up to a point people.

driggs, thanks for the feedback, clearly I had no idea what he was talking about, and I atleast thought it would have been a a turbo to say the least. None the less I will be more specific next time.

P.s. I"m doing a search as we speak but keep finding different answers, so does anyone know the exact specs on the turbo that Comes with the STAR kits.

T3/t40b with a Stage V turbine, is basically what I've been able to confirm exactly.

I want to know the opening of the turbine specs, the snail of the turbine size, and same of the compresssor, also the size of the wheels would help as well. Thanks...and sorry for the hijack.
