Supercharger Question

[CamaroAdam73]

honestly i think you'd have more power, better reliability, and for the same or less money if you just built the engine.

That would depend heavily on the power levels you are trying to attain.


Exactly. For what you'll have into building a supercharged engine, i (or you with the right know-how) can build a 406/355 that will devistate the boosted small block, for the same amount of money, maybe even less.

With a small roots style blower like mine, maybe. With a larger roots and/or centrifugal, I doubt it.

Also, if you're really considering boosting a build, you need to consider the rest of your drivetrain. It might not hold up to the sudden power surges.

Don't doubt, believe! My friend has a late model, that i've helped along the whole way, i just don't have enough into it to take part ownership. And the 406 we have for that, is pushing 670HP. The downside is, it's not tame/ streetable at all, peak power is right around 7500-8000 RPM. And i've seen even more wicked, nasty small blocks making more power, naturally. Superchargers just help make that power, and make it streetable.

I still doubt it. There is a limit to what any small block head can flow. And when you reach that limit you stop making power. When you start packing air/fuel in, that limit goes away. Add an F3 procharger and your looking at 1500+ hp. Something very difficult to do with an NA smalblock.

What is your budget for heads and misc. stuff to go with them?

You can look into the Edelbrock line of cylinder head packages that come with the heads, cam, and intake manifold that should all match, or you can piece it together a little at a time as you can afford it.

670 out of 406 cubes! wow who did the dyno work on that one! i dont believe in dyno numbers, i want to see a time slip! and i'll take a boosted small block over a n/a one anyday !

Yes, chargers can create massive power, but think about yow much money goes into those engine, before the forced induction. And how much power they make on their own, or if they had the compression.
to me, it just doesnt make senf to go forced induction for a lillte more power, for a LOT of power, yes

I was talking about keeping it in the sane power range, lol. Yeah i doubt you'll see a naturally aspired small block crank out over 1000 ponys, if 1000 at all. I've seen/ heard of 800HP+ but that's professional race teams.

If for some reason you feel the need to tow boats into harbors with your car, then by all means build a 1500HP small block.

But as for making between 400-500 HP, and keeping it streetable and within a decent RPM band, naturally aspired takes the cake.

I got 200-300 in my engine minus the heads, cam, blower.

Keeping it streetable and not having to rev it is the epitome of superchargering. Like stated before, i have less than 300 in my shortblock and will turn over 500lb-tq before 2500 rpm. Not easy to do na. And my supercharger is about the lamest of them all.

 

[CamaroAdam73]

I still disagree, right heads + cam and you'll end up with the same results. And not pushing over 6200 RPM.

Don't get me wrong, your setup sounds t*ts. I'd love to see it in action, superchargers have always been something I've wanted to build. How's the maintenance on that supercharger? I heard you have to change your oil more frequently?

And you said less than 300 dollars into your shortblock??.... Are you running cast pistons/ rods in it? Because unless you robbed the parts store, you'd have at least 100$ into bearings and rings. That leaves 200$ for a crank/rod/piston setup.
I'm guessing since your supercharger is of the tame kind, you're still using a cast crank?

 

[megaladon6]

$300 in the shortblock, but how much in the heads? and in the charger? and the carb?
