My car is a 355 ati procharger p600b with 12 psi.

I have a 52mm throttlebody on the car and 44lb injectors which are almost maxed out.

When I decide to get new injectors, should I also consider going to a 58mm throttle body and having work done on the manifold?

Or just save the money and spend elsewhere.


Thanks.

save your money and spend it elsewhere, the blower will force the air into the motor, going from a 52 to a 58 will net you next to nothing. If you were aiming for a maxed out NA build then yes. Headers, cam, bigger head unit, better heads, better intercooler etc are where its at.

 

Yea..I'd like to get rid of the p600b. Ive had it forever but funds are short.

I think I'll look at the heads next. I have the majority of what you mentioned already upgraded.

Thanks for the input.

I gasket matched the intake runners to the head runners for a small gain. The Holley 58mm throttle body didn't help much at all but it sure makes the underhood look alot better.

 

Measure boost at the disharge of the blower, then in the intake manifold. Whatever the difference is, is what you stand to gain by upgrading the MAF and TB.
