Can you have ITB's and a Turbo?

[kpowell911]

Just wondering if you can ahev Individual throttle bodies AND a turbo on one engine?

thanks

Don't think so as a TB sucks air and a turbo forces it.

I stand to be corrected?

 

[jamesp24]

you can have a turbo and a supercharger which is nice

Thats what I thought?

Yes you can fit throttle bodies and a turbo, but the gains of bodies over using an inlet plenum are not that big enough to justify doing so on a forced induction lump... So i heard!

Pulsars have this setup

 

[Batman]

na sucks it in, turbo uses exhaust gas pressure? i dont know exactly how a turbo is pressured but as i said you got the £££ you can even go to the moon

 

[Burgh]

nissan sunny gt-r have ITB+ turbos stock........ so of course u can have them both..

Throttle bodies dont suck, inlet pulses and pistons do, if you blow air through itb's they will flow it

[Djw John]

Yeah course you can, every turboed and inded every car as at least 1 throttle body so why not ITBs, just be silly silly money and most likely need to do a huge amount of strengthning work to the engien to take the pressures

 

[number1]

Wont be any extra inlet pressure caused by fitting itb's

Unless you turn the boost up

Wudn't have thought so mate, best bet is to get intouch with Andy @ GDI

Was more thinking the power it would be running the bottom end wouldnt manage for long!

 

[number1]

Depends what engine your starting off with.. most F7 engines i think are good for about 220-240 on a good standard bottom end, not a clue on the f4r tho...

Lol at ITB's sucking air and turbos forcing.

 

[kpowell911]

i dont know alot about engines, I was just asking if it could be done on an engine, AS in physically possible. The fact i posted on cliosport doesn't mean I intended on doing it to a Renault lump

 

[mini-valver]

I wasn't incinuating fella! A Thottle body is just a point for air to be passed into the engine, wetehr it be NA suction or forced. You can Turbo, supercharge and ITB a car if you wanted.....

T.B;s inherently increase volumetric efficiency of the whole inlet system, so using them with a a turbo will yield gains, and if you were building a turbo engine to the nth degree, this is what you would ideally do.
Cost implications however mean that many people at "road level" dont.
equivalent gains could be got by upping the inlet pressure by a couple of PSI.

 

[David Ramsey]

Yes you can but it's a lot of expense for the gains

 

[Andyman]

Yes you can but it's a lot of expense for the gains

How do you know about cost vs gains?? Its never been done on a Clio. Could get you 500+ and be very worth while :rasp:

Feel free to show me turbo car that gained 500bhp through ITBs lol

It's possible I'm sure, but ask yourself how many you've seen with the both?

That answers the question.

If it was definately worth doing it would've happened many times. A waste of time, effort and money.

 

[ChrisR]

Yes you can, remember some cars have an ITB setup in the sense of the word as standard, like M3s. So when people turbo those they are ITB and Turbo, I think

 

[Andy GDI]

Toyota 4AG has Throttle bodies as std.. you add a plenum and some form of boost.. SC or Turbo...

I dont see the point costwise of adding bodies and a turbo or sc to an engine that does not have them already.

 

[ditz]

yes and no - you can use a turbo and indivudal throttle bodies - as mentioned the toyota 4ag and the nissan sr20det both use throttle bodies with forced induction..
but the throttle bodies need to be sealed - ie capable of running forced induction otherwise they will not function.
same way back in the old days on the old metro turbo engines the su carbs on the turbo/na cars were different

 

[JW]

Yes it can be done. But like Ditz said they have to be sealed.

Here is a 106 with bodies and a S/C.

as long as the fuel preesure was substantially greater than the boost pressure, they will function fine. of course they have to be sealed, they wouldnt be much good otherwise!
