just wondering.

how much hp would you get compared to a s/c or turbo.

O5_TRD_tC

theres more than 1 person who first started with a S/C then switched to turbo.

joeya28

^^^ no no im wondering if anyone has done ITB-individual throttle body's. its an alternative to forced induction. sorry if i was a bit confusing i was asking if anyone has used ITBs on a tc and how much HP they got or could get by using them

O5_TRD_tC

oooh that i havent seen...

hip_2b_sqr

seems like 4 throttle bodies + 4 mafs = 1 confussed ECU.

yeldak

I can't remember the name, but there was someone on here a while back that was going to do this.... and then scrapped the project.

TCpete

2 ppl... me and davedavetc...

joeya28

you have it?

hip_2b_sqr

I think MotorFX had done that to a XA but never could get it to run right.

nebster

nobody has done it, it has been attempted but no success

short answer none, you wont gain any power just looks bad ___

O5_TRD_tC

bad butt indeed!

joeya28

their no way you wont have any gains with itbs, what makes you say that

nebster

because? you're not going to get the benefits of a supercharger / turbocharger, you're not compressing air in, granted you'll have increased intake velocity but you'll have more heat soak better throttle response. basically its a show mod, you shouldn't expect much more than stock

TCpete

ben sorry to burst your bubble but its not a show mod at all.... its actually fully functional and you actually do see gains from ITBs... average gains are from 15-25 whp .... i wouldnt have tried it if it was going to make me slower....lol...

BTW im still trying in my head how to make it work.. the DBW is the only issue..

draxcaliber

really seems like a needlessly compliated investment and it would only be worthwhile if you were doing a complete n/a build up on the tc engine with high compression tuning.

yes, it can be done, but what do you get in the end? how much power do you think you would make?

joeya28

i don't think that right. sorry to disagree but a lot of kid get great gain on other car esp if you use deferent cams. also if you wanted to run a a turbo on ITB its possible, guys use special manifolds that go to each throttle body

joeya28

haha idk how much power it would make thats why i was asking. and it not something i would do for a every day driver but i was interested to see if someone has done it. its more of a track car thing. not to realistic for every day.

draxcaliber

how would you have a turbo or supercharger with ITB? you would have to have a common intake manifold going back to the intake side of the cylinders from the compressor.

from what i've just looked up, it is all about getting the maximum amount of power out of high compression n/a engines.

joeya28

thanks thats more of what i was looking for. are you still working on it? i would love to see some pics.

they are usually for n/a set ups but i've seen some vw's with ITB and a custom manifold feeding to each TB

TCpete

not with s/c but with turbos i think ppl are basing the post off what SOME turbo manifolds used on the inside which is a velocity stack shrouded by the rest of the manifold... similar to ITBs only the velocity stacks are out in the open and not covered.
