that's not very much boost at all, but it sure is a bunch of RPM.

that's about what boost my V3 sees stock.

 

That lower pulley you expect to see what boost? Its about equivalent of 2.4 pulley, cam, longtubes. Wonder how much would gain with more TB?

It doesnt lay over even at 7300 rpm, just flat

 

LSA needs a cam more than anything else, if you want to make power.


CNC ported blowers, heads from WCCH, new Eaton rotor packs for your LSA blower, Mamo ported throttle bodies and more:

Yea, unclear as to stock cam or not for OP, I took it to mean it was aftermarket.

 

I️ guess in the title he is implying an aftermarket cam. I️ didn’t notice that part.

 

180-ish boost is about right for a stock car with a 2.5 upper (depending on elevation). Your pulley is equivalent to a 2.4 upper, so with the cam and headers, your boost seems about right. Without cam and headers I would expect you to be around 195.
