throttle body

[EB6]

I've upgraded my EB 6 to have a stage 3 crow cam, ported head, tuned length extractors and 2 1/2' exhaust and uni chip. its currently making 130rwkw but im still after more i know boltin a blower on the side will do it instantly but there is no challenge in that. What i want to do is up grade the intake manifold to ef so i can have dual plane but what im stuck on is the throttle body. Ive been told if i upgrade that for a large one quite considerate power gains are avaliable. What i want to know is if anyone has done something similar or knows about doing this and the effect it would have.

IT's Performance have a twin T/B setup, which has some very good gains. Have you got the stock Airbox still in place? Make sure you get a nice snorkal to get heaps of air in. And then maybe look at getting a 3" pipe from the airbox to the T/B ($375) if you plan on keeping the one T/B. Speak to JMM or De Filippo for a pre-made pipe.

The stock T/B has been tested and doesn't need upgrading unless you are pulling some really big numbers.

Ford put a 70mm T/B on the AUIII XR8's that were pulling 220 (~170rwkw) at the fly. Unless you can get one cheap, snap it up. Otherwise you might not get any gains.

You might want to look at getting your bottom end built up, and gain some power down there.

Just my 2c.
