WHP numbers on a NA bridge port 20b

So I was ******* around today searching here and also on google. I went to the www.3rotor.com website and checked out there last project according to the site. It was a NA 20b with a nice bridgeport and a ITB setup. I was confused that the car only made 300 whp yet Gtorx7's car made 350 on a standard streetport. I am going to assume they didnt use the s5 rotors but still 300 whp seems really low. Ive also read that a BONE stock engine is capable of making 275 whp NA of course. Do those numbers sound right to you guys.

Too many variables. Porting, setup, dyno/condition differences etc just to name a few will have an affect on power. I'll throw this into the mix just to confuse you a little more, I've seen NA 13B's make 350rwhp.
So basically it all boils down to the entire combination.

300rwhp can be attributed to a exhaust not being built properly to let a bridge port breathe. I dyno'd twice two years ago, 310rwhp on a mustang with ECU issues above 7100 rpms, then again later (car fully sorted and broken in) pulling out to 8500 rpms and made 348rwhp. So I bet its the exhaust in the second gen being the issue.
