individual throttle bodies?
 

in the 4 cylinder atmo world the most exotic induction setup appears to be the Individual Throttle Body

you also see them on sportsbikes, and in F1

but you don't see many on V8s, except really high revving flat plane crank stuff like this

M5s and ferrari 360s

has anyone here used them? and if so how do they compare to LS manifolds etc

I have done a couple. Here is one.

GEEEZUS Rodger! Every time I see that pic I see more and more detail. I could park that in my livingroom and be happy to just stare at it.:drool:

Yeah sometimes I think the worst thing I ever did was install a body on that chassis.

The IR intake setups are pretty common, especially on a V8. I have 4 in my shop currently.

The IR intake is only a small part of it. It just adds to the whole package. Pure art as far as I'm concerned. The body was a killer piece in itself. Either one separate or together would look great right here in my living room!

Thanks but my house is pretty small, So i would have to park them on my neglected lawn out front.

Thanks again. Kinsler makes the best set up their is.

ITB's for LS-1/2's
 

"Stacks", "ITB's", "Hillborns", are common names for an engines inlet system that has ONE runner for each cylinder AND a separate butterfly for each cylinder to meter the air flow.

Most of the common American systems have two problems:
1. The throttle shaft is steel (parallel to crankshaft) and binds the "butterflies" in the aluminum bores when the engine heat changes from hot to cold.
2. The airflow at Idle/Low Angle is VERY hard to equalize AND there is NO passage way in the casting to communicate the correct vacuum signal to the EMS.

I have never tried the Pantera system but I can tell you the Kinsler unit has a unit to install an idle air stepper motor on the idle circuit. There are many brands on the market that do not. But we have that circuit on the truck which is why it idled so good out of the box on the dyno. The guys at Westech commented on the idle quality when we ran it, they were not excited about tuning an IR engine, because of that very fact.

You can see the 8 stainless lines and the stepper motor and airfilter in the manifold. We since relocated the stepper motor down near the oil pan.

Kurt used a Kinsler IR setup on an LS7 and used a BS3 computer.

ls6 454, enderle 8x2.7 inch butterflies, tec3 cpu... dont have a more current pic.... and its in my 32 roadster ... (deuce_454)

the fuelrails are inboard between the banks and the alcohol lines are for the MAF if you were wondering... (im considdering not running the MAF and doing the load tabels based on TPS instead.... any input on this???)
