Ok I have a very weird problem. I have a 355 Supercharged. It has a pressure problem with oil coming up the top bolts ( https://www.thirdgen.org/techbb2/sho...hreadid=300567 ) if you want more info. I don't know if that has to do with the problem though.

However, here is my problem. When I am cruising, lets say 2 RPM and I push the gas ALL the way down, it makes a real loud sound that doesnt sound quite right (its the supercharger) and it slowly goes up to 3 RPM and maxes out there, it WONT go above 3 rpm... maybe 3100 rpm...

But when I am at a stop light and floor it from an idle, it goes real high around 5 rpm.

Anyone know whats going on? Here is a pic of my engine.

 

Can you bypass the SC to eliminate a variable?

 

Take it out? yes I can do that, not today though... *** its running like a frekin KIA. I was on the highway just a minute ago and I floored it from 1 RPM, it went up to 3 RPM and A FREAKIN MINIVAN WENT PAST ME and we got off the same off-ramp.... something is definatly wrong, shouldnt a 355 SC v8 5.7l engine be able to out speed a minivan? I think so...

Anyways ill prolly do it tomorrow if I have the time. But every time it reaches 3 rpm the supercharger makes an awful noise, so I think that might be it, but can a supercharger really bring down that much HP if its busted?

 

I don't mean remove it off the engine, can you run a bypass belt so the SC isn't working/spinning?

 

Oh,,, I dont know maybe... but wouldnt that still make air flow through it and make the fans spin making it less HP than if it was off?

 

You'd be lucky if you could get it to start then.

 

That's what I thought.... id be like blocking the airflow

 

Change your fuel filter and try again before I'll offer any more suggestions.

 

Ok ill do that, is my fuel filter the one on the side of my holley carb, the summit racing chrome cylander? You can see it in the pic is that it?

 

Good point, just read the sig line and see he's carb'ed.

 

Either way, hard to suck air through a stalled roots unless it has a bypass valve.

 

Ya, I've been long to often into EFI and seeing/hearing guys with paxtons, etc, that bypass them...completely different beast and easy to do so.

Teaches me to yak, then look.

But hey...least I got the poor guys thread started
