Quad Throttles What Are The Gains??

[TODA AU]

Are Quad Throttle worth buying like r there big power gains??

If you've already got cams, compression, capacity, etc, then yes...
They are worth it.
But only when used with an airbox.

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 kind of compression and capacity would you recommend?

[pat88c]

What kind of compression and capacity would you recommend?

Would have to be anything over 12.5 to 1and higher compression

Would have to be anything over 12.5 to 1and higher compression

surely you wouldn't need a comp that high to see the benefits of itb's?
