Ive decided to go with superram setup for my 91 formula 350 intake modifications. I need to pass emissions which I understand lets out the stealthram, and I think miniram too. What's the deal on the Vortec supercharger? I thought someday to go to that (if I win the lottery or something). Can you pass emmissions with that (probably a stupid question). Also with the Vortex SC what kind of intake is used? Does it contain it's own or do you bolt it onto your existing intake (like the supperram). Sorry about the stupidity but Im kind of new at this.

 

You can have a supercharger and a superram. If that's not correct then I'm thinking of a turbo. That sounds so cool - I have a Turbo Camaro w/ Super Ram... yeah neato. =D

 

The supercharger bolts to the front of your throttlebody, you can use whatever intake pleases your heart.

 

IK, but does it still make a difference in performance or is the supercharger overpowering enough that whatever intake you use is the same? In other words could you get basically the same performance with just a stock setup, at a much cheaper price obviously?

 

I would guess that a miniram or even a LTR setup would be better suited to supercharging than a super ram. A super ram has a huge plenum volume, and when you're dealing with forced induction, I believe that it would be beneficial to minimize plenum volume.

That being said, it's been done before. Tom Panaseny (sp?) built a beautiful 89 IROC with a 420 cubic inch small block. It had a super ram and a blower and he was running 10s with 10" slicks.

He sold that car to somebody in NJ a couple years ago. I haven't seen anything on the car since.

 

The superram plenum will be more beneficial I think. The more mass of air pressing down into the chambers the better. Some of the speed density cars actually come very close to showing a slight increase in pressure with superrams on them.

 

I dont think the superrams large plenum would hurt all that much off the line, and it flows so nicely I thinka blown superram 350 would scream like an angry... er... something or whatnot

 

The miniram and stock TPI are known for fuel (actually air) distribution problems in extreme forced induction application. Whereas NA both manifolds tend to run the front cylinders (or front runners for TPI) lean since they get the first shot at the incoming air, both manifolds tend to make the back cylinders lean under boost due to air 'stacking' against the back of the manifold. Over the years i've been led to believe that the superram does not have the same kind of problems.
But in answer to the original question, yes you will still see gains from a superram with a blower compared to a stock manifold. Not as big of a difference as you would see NA, but it will still help anyway. Reason is, long runner TPI is not as big of a restriction under boost as it is NA since the air is being forced through the runners, even at high RPMs where normally the extreme velocity in the runners becomes a hindrance.

 

This is great information, exactly what I was looking for. I don't know if I will ever get to that point (money restrictions) but in the meantime I'll have the superram and a pretty hot motor to enjoy. I think its going to be the best aftermarket intake for me since I have to be emissions legal in Houston Texas and eventually it will work good with the Supercharger. Thanks
