A guy i know does porting & polishing for intake manifolds. I was thinking about having this done. I know i will only gain about 4-5hp NA but i am juice. I al also running a higher flow fuel pump and im sure that will help out the higher air-flow. What are your thoughts?

I was also thinking of having him bore my TB out a little. Again, ideas?

 

Unless this guy really knows what he's doing (has lots of experience with this engine, flow bench, etc.) he do more harm than good. I would just stick to port matching and removing casting flaws.
A high performance fuel pump is a non-entity.

 

if u wanna do this, do this at Extrude-Hone...

 

theres a recent thread about this in the 3rd gen forum,and we all deemed it useless unless your runnin forced induction..or at least useless for the price

 

I know its useless when its NA, well actually, ill be happy with 4-5 extra HP but i am only considering this b/c i run Nitrous. Even if off the bottle, i will not suffer @ any power loss.

 

I don't think you'll get 4-5 HP Check it out at http://www.mobiletek.net/news.html

 

Port matching is a good thing to do.

 

Don ported the exhaust manifolds (in that article). He gain no more then 1hp.

I am hoping the intake manifold would be a different story & create more power. I guess ill have to see what it does when i get this done.

 

I think you should wait and see what kind of gains can be achieved from the variable intake from Road Beast before you decide on doing this. It may be a smarter choice.

 

this is what I was going to say

 

It may be a smarter choice but $750 is a bit too pricey for me.

 

I have an extrude hone intake manifold. Check out my dyno plot below. It basically gained a bit over 5 HP but even that is misleading. The two plots show more or less a before and after. The EH manifold mainly just moved my peak torque rpm up from ~4600->5000 rpm, which is where the HP increase came from. In terms of better acceleration, it's basically nil.

Spend your money on something better. Like the middle east intake. That'd be just $100 or so more and DOES provide a very substantial HP increase (20+ would be my guess).
