Are Quad Throttle worth buying like r there big power gains??
If you've already got cams, compression, capacity, etc, then yes...Quote:

Gains are (B18C) 35hp @ 5500rpm & 10hp top end.
- Vs Itr manifold & 65mm throttle.
- No change to port shape.
Change the port shape together with clever portwork,
You can see an extra 50hp @ 6000 & 40hp top end.
But if you've got a low budget shitter, don't waste your time.

what he said.
Wow thats a massive increase in midrange!Quote:

Capacity should not matter. But will amplify the effectiveness of your modifications.
Compression - as high as you can live with....
Would have to be anything over 12.5 to 1and higher compressionQuote:

What need to make power cams, compression, fuel and air flow
Most race cars run anything from 12.1 up 15.1 and some of turbo setup i seen running around at the drags run 12.5 to comp plus 20 psi boost
yeah, but doesnt mean you ned massive comp ratio to get any benefit. Just means the higher it is, the more youll get out of it.
There are some on ebay,they previously reached $600 plus and have since been relisted so obviously the owner didn't get what he wanted at that price.Can get them new for $900.Too much hassle without a cold air box but better than nothing.K series would be trick though.The thought went through my head as I have a K without an inlet manifold.
