13B Power @ 1 bar absolute pressure, to see what you might have if you MAN UP!

Racing Beats full Peripheral Port Turbo's are around that same ~270bhp level btw. But to attain that you need a full open exhaust! not practical even on race tracks. I listed a few of partial pp's in the first post, worst or just a bit over compared to RR street port. so you can see there is not much in it really at end of the day once you have a decent street ported motor.

There is a big gain from small stock ports, but how much power do you want

190 odd bhp level to 240bhp~!

Updated with more figures *directly from dyno tests-rather than trying to remember the numbers!* from various tests I have on hand. Gives a good range of 13B power (@ 1 bar ABS) for various port configurations and turbo set up in various guises...... Compression ratio's listed, all high power (non Jappo or Racing Beat) cars (used only as external comparisons as data is trust worthy) are water injected and tuned the same (as I did them!) so figures are what they are for the engines efficiency. A good maximum street port therefore would suit many people.

Amazing correlation too
