Cosworth enlarged throttle body

I have seen them before on big power engines.

‘’The ideal is individual throttles per cylinder. You can run over 500 bhp on standard though.

I have the throttle body from that link on mine. Sent him mine and he modified it. Really nice work and fast turn around time. Initial impression is good on the dyno but wont know for a few more weeks.

I’m not 100% but I don’t think a bigger throttle housing makes that much difference, you can still get massive power on the standard sized body
