Does anyone know if the "FEED Big Throttle Body Upgrade" will provide any noticeable benefit or if it will effect regular driving? I searched but couldn't find anything related to this.

There are several people who do that here in the states. I've never seen anyone do a before and after dyno, but I'm sure if you port match the entire flow you'll get some improvements.

 

Do you know anyone who does and any info if it will effect regular driving? I know the benifits are reaped if you do everything but you gotta start somewhere. I already removed my double throttle body and bored out that since the center section is no longer needed to hold the butterflies.

i have the feed throttle body.. i dont see much difference to be very honest but i dont have dyno numbers before and after

 

How does it drive compared to stock?

I've heard that you'll feel/see noticeable gains in power if you port the TB and both manifolds accordingly. Your car will obviously have to be tuned for the porting though in order to see noticeable gains.

 

Of course it would have to be tuned if it provides more airflow. Does anyone know of the places in the states that would have something similiar to this?

Just a bump for the morning crew, if not I'll order the FEED one from rhdjapan.

Pettit has one on their website for $500. No picture though. You might want to call them and ask about it.

 

you should be able to get your stock one bored out for 300-400 bucks here in the states. a lot of old school hotrodders do this so they can keep the stock look

I ordered the FEED one from Japan 2-3 weeks ago. Should arrive sometime this week.

I have the FEED TB, GZ LIM, & stock UIM extrude honed. However, they are all sitting in a box in my garage, so I can't really help out with numbers.

After ordering mine from RHDjapan, I found out that BDC does port work on TB's and I could have saved about $500. I guess I get to say it's FEED though.

Here's a link to Brian's website.

OR you could have simply sent you TB to Russ Collins...

 

i had my manifolds ported by rotorsports racing(with flow matching too)..He can also do the throttle body, and defenately for a lot less

 

How much did he charge?

 

We do offer the big bore throttle body and Extrude Honed manifolds, the combination is a prime example of "1+1=3" instead of 2.
-the results are VERY worthwhile-the extrude honing alone increases total airflow through the manifolds by 38%, flow is more evenly balanced and they are returned with a "airflow" data sheet containing both before and after. The throttlebody modification is for the 2 secondary ports only.

Hey rotorhead, if i get the xcessive lim, can you still do the ceramic and honing with their lim. Any dyno reslutls??

 

+1 on the xcessive LIM, can you flowmatch the UIM and throttle boddy to that one or do you still have the hone it out some more?
