LS! stroked. What supercharger?

[Brett SS]

The best suggestion so far. A crate ls3 will be much nicer to drive then a stroked ls1, be better on fuel and will probably make more power.

Yes and no, if you are wanting a supercharger one day you will want to wind up the boost past the point that the stock pistons can handle. Trust me I know... lol

I'm at that point now with my LS1 as I'm running 10's with a PWR122 top mount blower running 10-11psi and makes close to 390-400rwkw. For me to wind up the boost safely any more I would need to forge the bottom end but that is a cheaper option for me than forging an LS3 etc as I already have the right cam, pushrods, heads, intake etc to go with the setup.

If I had the money I would forge my LS1 and put a 2300 blower on top of it running about 18psi...

What Jake from GM and Brett ss said are the most sensible posts, a pd blown 383 would be ace, pd blower are so docile when you want them to be. Light throttle is off boost so it's just like a normal car, mash the peddle and she goes. Why do you think walkinshaw, Mercedes, corvette, ford, super snakes all run pd blower because of drivability. Your on the right track mate and don't be scared off 400+ rwkw on the street is beautiful as long as you are sensible driving to the conditions and know your car.
A blown 383 you'll find no need to rev the guts out of it so streetable.
Best of luck do your research and do it right

Just some thing I noticed . If you went 383 with a pd blower ide be going an overdrive ballancer not an under drive ballancer

why go with a larger balancer? you're only going to increase parasitic loss and destroy your accessories faster when you spin them too hard. Just use a smaller pulley on the S/C?? surely thats a hell of a lot easier.

At a point of going smaller on the blower pulley, you lose wrap and gain belt slip. An overdriven balancer will outweight parasitic loss no worries. ( but yes will be harder on the accessories i guess) Total Parasitic loss from accessories is about 15-20rwkw on a LS3 N/A!
Jake,

Jake,

Agreed also if you went a 25% under drive you would need to make to the blower pulley smaller again to make same boost increasing chances of belt slip even more

Or this...

Just read the specs, If I can see right cam is 215/247. Massive split....interesting on the intake side that it isnt bigger

Way to much split. Your loosing dynamic comp for zero gain. A 215/225 would out power it everywhere.
