My car runs the times in sig just wanted to get everyones opinion on wether or not the stock throttle body and 1 5/8's macs are holding me back. Car put down 460hp on Dynojet. ported heads, 9psi boost no cooler,cc 305 cam

 

Doesn't seem too bad for whats done. I would think a colder charge (cooler or meth or something) would do more for you than the TB.

Guessing the S trim is maxed out? Best answer is always more boost

 

No S-trim isn't maxed but my 48 lbs inj are. Still stock pullies on the S-trim.

 

Any other opinions? Seems some others are running better or putting down more hp compared to mine but, similar mods.

 

I'll be the first to admit, I am not as knowledgeable as most here but your ET and MPH seem pretty good for what you have done (unless the car is completely gutted weight wise).

I think may be a cooler of some sort may help too. What are your current IAT at 9#?

I have been out of the car scene/thing for a while (4 years to be exact) but I remember reading something here that Non Intercooled boost usually yields about 15HP per # of boost and an intercooled boost may allow 20HP per # of boost (maybe more pending increase in timing).
If your IATs are high, a cooler could (in theory) gain another ~45HP that what you are currently (maybe more).

Thx,

I believe the IAT's lat time out were getting to at least 160 so I know it is hurting me. I have a a/w cooler I just need to get it going with an exchanger and pump.

 

Do you mean you have it in your possesion but its not installed?
Or its in the vehicle but does not have an exchanger and pump?
If so is there liquid in it?

That would definately hurt you, heat soak FTL.

 

No not on the car just in my pocession.
