a quick throttle body Q?
a quick throttle body Q?
i noticed alot of bike carbs are fuel injection? does this mean thay need a ecu? and will thay still work on my 340 1.7?
hears an example.

Surly no bike "carbs" are fuel injection, as that's a contradiction?
I'm no bike expert, but I thought they mostly used carbs instead of injection. If they are carbs, then no, you won't need an ecu.
Again, no expert, but I think that's a throttle body that controls airflow, and uses fuel injection. Thus it's not a carb, and it would need an ecu.
Please, anyone correct me if I'm wrong

Re: a quick throttle body Q?
The link shows an EFI setup with individual throttle bodies, so you'll need an ECU to run them, along with all the other electrical gubbins. To fit them to a 340 would mean a lot of work and lots of expense, but IMHO individual throttle bodies is the ulitmate setup for any engine.

Except for a race spec quartermile engine. ITB's have no advantage over the plenum-type setup in an engine where full power is used almost always.Carl wrote:but IMHO individual throttle bodies is the ulitmate setup for any engine.
But for rally/track use ITB's are almost always the ultimate solution, even better if they are guillotine-type.

Yeah fair point, hadn't considered that. Should have said for any road engine (or track or rally)Fuse wrote:Except for a race spec quartermile engine.

Re: a quick throttle body Q?
Assuming the same overall throttle area, and no other impedement to airflow...of course that's true. But the B200E manifold vs a pair of 40s? A big difference!Fuse wrote:ITB's have no advantage over the plenum-type setup in an engine where full power is used almost always.

Its the improved air flow that makes the difference. A well flowed common port set can produce the results but it's not an easy way to go.

Yeah powerwise it's the same if both setups are adequate enough what comes to throttle body sizes etc... but ITBs give you more linear gas response and control at low throttle plate opening angles is better. Both are much appreciated features to have in a rally or a track car.
With plenum&one-throttlebody-setup the air flow can vary much and with a little increase on gas engine can get "too much" air, and power will suddendly increase a lot, so it's not as precise in controlling the power as ITBs. On full gas this of course won't matter.
And when using ITBs with highly tuned race engines, which have cams with a lot of overlap, pulse chamber can be fitted outside of the throttle plates so you get rid of the problems with the "bouncing" of the intake pulses in the plenum in the low rpm levels when the flow of the air is slow. But I think this type of stuff is hardly the first problem in a street car..
With turbos it's a bit different thing again with the ITBs too. Most of the time the gained advantages aren't as big as they would be with the NA cars, when you compare the price of the ITBs and harder tuning with the ITBs to the plenum type setup in a turbo car were the gas response isn't linear anyhow.

850s and 960s have larger TBs. I think the 960 one is larger than the 850 one. 760 V6s have the same throttle body size as a B200/230, I think.
