Supercharger on stock internals?
Anyone running a s/c on stock internals? If so how much boost? What can the stock engine handle? I really want to build a block, but no idea how long that is going to take and that intake manifold is going to be staring me down all the time. Lol. I know more needs to be done to manage a s/c just wondering if the stock refreshed engine can handle boost from an M90!

Re: Supercharger on stock internals?
A stock motor can handle boost. Look at what SomethingElse has (YT's old car). I think he is running 9psi on a stock motor. An M90 is a bad idea though (heat issues) and one that has been talked about a lot on here. Also, talk to Old Tom about his set up.

Re: Supercharger on stock internals?
Nate has a supercharger intake manifold. If you're serious, talk to him. You will need to get the supercharger separately, and some other stuff, but it's very doable. Only like 9 or so psi has been done safely.

It's tuned to the rich side, but on Ultra 93, the Hydra shows no signs of registered knock. I don't know how long it will last (and I anticipate changing the engine someday), but there's nothing kind about the way I treat it. Roots = heat for sure. If you're doing the popular Impreza side-mount w/intercooler gig, you can probably do fine, but I'm a little leery about the idea of an inverted, intercooler free setup. With a twin-screw on 9psi uncooled, you're looking at 180*F going in as it is.

Engine knock = bad. Opportunity knock = good!

Re: Supercharger on stock internals?
Yea about that manifold that Nate HAD! No idea you were running stock internals on your Svx LetItSnow! Good to hear I can run something with this modified manifold on stock internals. Not going to be done till next year so the Reading meet should provide my with some info.

Re: Supercharger on stock internals?

Re: Supercharger on stock internals?
Same thing as LetItSnow. Just a different manifold and I am running 12-14 psi, but have a 9psi pulley as well.

Consider the STX setup? Might be a better path!

Re: Supercharger on stock internals?
Pretty crazy looking setup there. So can you just run better (ported and polished) heads different valves and cams to handle the power I am going to be putting out? I know internals would be outrageous right now, but heads can be done for a good price.

Re: Supercharger on stock internals?
Cams will run you around $175 a piece if I remember correctly (for a regrind NOT new) and I dont remember what my valves cost. All in all my heads ran about $2k I think.
