Max known BHP on stock ports?

[L18M]

as above really, just wondering out of curiosity :p
and what other mods you would need if it gets into stupid power..?

[Furb]

i currently run 320hp on stock turbo and stock ports, maybe more soon.
 
J-rat on RX7club.com has from what i know produced the highest hp on stock ports with a large turbo. from what i\'ve read he has produced around 450-500hp...

Presume with a bigger turbo you could probably squeeze out over 300bhp - but TBH most people who upgrade the tubby would mathc it with appropriate porting etc.

There is another guy on that forum who has produced well over 700bhp on a 13BRE on stock ports using a massive turbo

standard RE ports are massive in comparison to 13BT or REW ports, so that doesnt count :Nono!:chat

[BlitzBoy]

ahh yes but the exhaust ports are tiny on the RE

indeed, that is the 13B with the highest potential for serious power!
Dragon performance has this in their drag-FD and is pushing 8-900hp :3gears-lh

[dthebuk]

i take it, its more than the ports that are different then?

[BlitzBoy]

best 13B is the combination of REW and BRE parts , but this has been discussed many times before
