Lsa blower question

If I'm at 10 psi running a 2.5 upper pulley. How much boost might I see with a 10% overdrive crank pulley?

What's the diameter of a 10% lower? Use that to calculate the rpms and see if it's worth it

+2 lbs. I'm working on the most cost effective 8 Rib setup for you. I'll reach out with that info shortly.

All the best,

Curious -- 2010_Camaro, are you looking to use an LSA drive assembly on your conversion? I can see an overdrive pulley available for that.

I'm wondering if there has been a 10% overdrive pulley for the LS3/L99 -- have not seen those if there is one...

I found a 8rib conversion with 10% overdrive but it's $1100

Really? JDP doing that? With the power you're seeking, is that worth the upgrade?

Thanks!

I already have belt slip with my current set up. Dropping anotger pulley size on the supercharger and going bigger on the bottom will require a 8rib belt minimum.

So, you're going 2.38 -- 8 Rib -- makes sense in that case. I thought ADM was also working on an 8 Rib too...

That is going to be a 'hot rod'!
