quade throttle bodies ?? whats up with that

[Tranzlogic]

Any of you guys even come accross a Quade throttle body on a street car ? i was just wondering how good they worked, pulled and so forth. i have never come accross one on a car. Maybe ill mess with one, one day if i hear good things

Individual throttle bodies, are great for ringing the some extra Hp out of a motor. They sound mean as f***, but on a daily driver they can be a pain, and they are pretty expensive. Some people custom make them out of motorcycle ITBs welded onto intake manifold flanges for their motor.

sound mean? anyone got a sound clip?

i had heard something of that nature, ive been told theres a hatch runnin around here with a hommade ITB setup. what do they use for filtration ??

[Tranzlogic]

and how would anyone go about running turbo plumping to one....like i said i have never seen one in action so i am clueless

[PunkAlex]

Filtration? ive seen em running just open throttle bodies (drag) and little cone filters (probably street)...

Turbo? THis is primarily an allmotor setup on hondas...the nissan skyline has an individual throttle body setup stock i believe, but it has an intake box (for lack of a better term) attached to the throttle bodies.

You can't run boost and ITB's. They are for N/A applications.

Crap.
You can run any kind of induction you like through them.

Show me a ITB set up that is boosted.

[Tranzlogic]

i wouldnt mind getting my hands on one and seeing if i could run boost on thru..or atleast constructing one and see what happens..altho on boost i think it might loose its edge tho....who knows

[jcrx]

Don't get me wrong, I am sure there are some versions that run the same individual plate set up for each intake runner inside of the intake manifold, but that's not what we're talking about. If you were to look at those, they would appear to be a nnormal IM.

For one thing, there is no point in having individual throttle bodies, and boosting it, that would defeat the purpose, and in order to boost them, you have to inclose them in an intake manifold.

The RB26DETT motors rock the ITB's.

You're right though, it doesn't make as much of a difference with forced induction as it does N/A, but it still does make a nice improvement in throttle reponse.

[jcrx]

That's the whole intake manifold designed to work with it's own system. I am saying you can't just throw ITBs on a Honda, and then boost it. And I'd like to see someone run a supercharger through them.

Details of the Chargecooler on a Lotus Esprit Turbo with a pic showing the quad thorttle body intake. This is a US spec car, with Fuel Injection, the rest of the world all got cars fitted with Twin double throttle body carbs.

This page: http://www.rh9.com.au/gallery_rh9.asp
Has HEEPs of pics of Skyline GTRs, and towards the bottom several pics of the RB26det, showing the inlet manifold, with individual thorrtle bodys, and plenum.
The SR20det used in the GRiR Pulsar also used a similar set up.
A search on www.google.com for "Sr20det quad throttle body" will turn up plenty of results.

and heres a Toyota Levin fitted with a 20valve 4age (which has quad throttle bodys,) that has then been turbocharged. The artcile is very full of itself, but the pictures quite clearly show a Turbo pushing boost through four individual throttle bodys. http://www.divisionone.org/inside/sule/sule.html
This is an existing N/A ITB engine, that has then been turbo charged, with no fancy inlet manifolds with cast on plenums like the Nissan engines.
