Independant Throttle Bodies (ITB's/IRTB's)

[LordWorm]

where do guy get your info from?
step 1 you need to tap each runner with 1/8 NPT
step 2 fit a vacum block also with 1/8 NPT fittings
step 3 set one of the outlet for you FPR and one for your map and one for your brake's
step 4 if you are running a MAF you will need a sealed plenum at the end of your ITB,s instead of just a air filter
step start car and check for leaks
step 6 is where you sink your ITBs to = or - 1lb at 900 rpm
step 7 slowly bring up your RPM's to around 3500 or so .at this point you need to set AFR with your wide band
PS you can run ITBs on a OEM ecu all day long

do your home work before you spend your cash

I get my information from talking to dozens of tuners and engine builders who have been there, done that. The fact of the matter is that you will NEVER get consistent map sensor readings by tee-ing off and blocking together 4 runners to read the vac.

I'd also really love to see you running IRTBs on an OEM ecu on the P5.....

By putting a plenum at the end of the ITB's to run a MAF you have basically just created a intake manifold with velocity stack runners. Might as well just use one throttle body at that point.

Independant Throttle Bodies ITBs/IRTBs

I was looking into getting a throttle body spacer and wanted to know if one was worth getting for around 50 or so. And what I could notice. Also if I could use later on an after market intake and throttle body too ? Thanks

wrong thread. Close tho, least this thread is talking about TB's...

You're not gonna really notice s***... Every little bit counts tho, I guess.

Just curious if anyone else every pursued this avenue. I was reading online about fuji-racing ITBs but I couldn't find a website for them.
