Guy Croft Racing Engines (205 Gti Flow Figures)

[christopher 5 1 Cars]

More figures for the 205 GTI http://www.guy-croft.com/viewtopic.php?t=45 Read the topic its really interesting. Or ask guys some questions on the forum directly. He is a very helpful chap

Quite alot of interesting info on that site.

 

There's a similar thing for a 306 S16 head (which is very similar to a 1.9 Mi16) as well - here

I just spent far too long reading stuff there...

 

this is worth a read too - http://www.guy-croft.com/viewtopic.php?t=48

too many numbers:S

 

but i have succesfully migwelded an rsturbo baffled sump! :S

i wonder what he tested them at as the figures seem very low. Perhaps Pumaracing could comment on them?

Think it said 10" water column somewhere.

[petert 588]

Yes they're at 10", where as others might use 28". You can convert from 10" to 28" but even then, the port might behave differently at a lower pressure so iit may not be an accurate comparison.

what would you guess he'd achieved at 28" ?

The port will behave the same at any test pressure other than where the Reynolds number is very low and that only applies to the first few thou of valve opening. Flow figures can always be converted between 10", 25" and 28" which are the main three standards.

Roughly 196 peak flow, beer mat calculations again. You can guess the rest back from that.
