itb's and runners

[Rallystanza]

are the T3s for the 101 or 111 throttles? (they have different transitions...)

They are easily die ground into submission.

I will be using them on the blacktop throttles and have checked it out. As per Gabe from T3 also.

It's a track car, don't stuff around having bends in the runners, just put the air filter in the boot. I can't find the numbers I ran, but with stock cams, a total runner length about 1" shorter than the factory runners should be a good start.

so your saying build some straight runners approx 1" shorter than the t-vis plate to plenum or head to plenum? would retaining the t-vis with the bigport head help or hinder?
and i spose once i have it registered cutting some holes into the boot wont worry me.

indeed the t3 adaptor sure is prurty, but i do like making my own stuff at a fraction of the cost that IMO works as good. (even if i am not talented enough to make it from alloy!).

it appears all these adaptors space the itb's a certain distance from the head. i could always make some short and long ones and see what difference it makes on the local dyno.

thanks guy's, appriciate all the feed back.

they are mostly reasonably short because in a RWD application the TB's will hti the brake brake master/booster..

with the boot, you can make longer with no worries

Valve to plenum distance is what the air cares about.. I suppose you could keep the T-VIS if you were feeling tricky, it should still help.

Now you're talking..

Having built one myself, I'd seriously suggest buying one. It's not an easy job.

Ill back that up, building them is a SERIOUS pain in the arse.
