Never seen these before but they look awesome! If they do as they claim on their website, they should be popular.

RHD Eng have a strong following with BMW crowd. I fitted a RHD ITB kit to a fellas BMW six and It's a good well thought out kit. RHD Eng is very helpful guy

ITB's are generally used in track cars because they help with transient response. They're ideal for cars trying to get back up to the peak power from a gear change. This is the case for most which are short trumpet.

On a dyno they generally don't peak as high as a dual plane and most have short trumpets so loose a massive chunck of torque around 3k-4.5k. These Race Head Engineering ITB's seem to have fairly long runners for an ITB setup so they should recover a lot of that lost torque down low. They should perform like a Holley Hi-Ram imo.

I actually found clips of this manifold on YT.

Look great. Here is a dyno run:

Yea, I actually went ahead and got a kit sent to the U.K. for my ls1 HSV.
Really pleased with it.
my car was cammed with a ls6 intake.
with this kit I gained 23 bhp , lost only 5 ft lbs at 3500, but the throttle response and idle has been much improved.
I have some videos search ‘Hoonatic Bloggs’ on YouTube
