ive ported ten supra heads this year and have two for saleim sorrey for not having any flow numbers so ill work on it and at tha mean time my flow bench is in the works.

Did you charge money to people when you ported these heads? This sounds a bit cletus like to me. If it isn't, the prove your point. That is all people want to see.

Hey joe ,

Email/ pm him , I'd like to know the results of that :naughty: . The emails I had with him says he'll probably arrange something like that .


Some of ya'll are awefully cynical too . Those hpf cylinder heads are what ? $3000 bucks or so and they don't have flow numbers either .

Here is what I got from his post. (Only the important stuff matters.)

He decked the block and they also milled the head. (Brought compression ratio up to about 9:1, but it could be higher, he does not know I'll bet.)

Ported the exhaust side 5mm. Good mod. Did this myself, and it helps for sure.

Ported the turbo. Also a good mod. (Guess what I have done to a few turbos? Basicly free power to clean up the casting flash, and smooth sharp edges to improve flow, yet does not kill your spool up times much if any.)

Is this kind of spool up possible on a stock CT with those mods? Absolutely. (The CR change alone will do most of it. Improvements to flow are just icing on the cake.)

The trick is to find out if we can run high CR's and high boost.. LOL

I could get get ~12psi on my upgraded CT26 in 5th gear by 2000rpm (if I floored it at 1500rpm). It started building boost about 1700 and ramped up pretty quick. Still, the time it took to get from 1500rpm to 1800rpm was so long it had no practical purpose -- but the claim seems legit to me.

My head was ported, stock valves, 3" exhaust with no cat or mufflers...
