Not sure how much hp was gained, but here's the post telling how much cfm was gained. https://ls1tech.com/forums/generation-iii-internal-engine/514551-dart-225-after-info.html
Isn't there a rule of thumb saying for x amount of cfm, that equals one hp? Isn't it something like 5cfm = 1hp?

You can port a set of Dart 205s out to the equivalent of a set of ported Dart 225s. The heads are pretty much the same except for the smaller valves and intake runners in the 205. That relates to more meat to take away with porting in the 205s.

You're right I don't have any idea why he's banned, but it doesn't matter to me. One less internet know it all that think's they're the begin all, end all of everything is out of here.
If you want a good porter who actually put down solid results get in touch with Greg Good. V6Bird another guy on here does a lot of work with them. He's also banned, but he actually puts down great results.

Bret makes his living by specing out cams. So I wouldn't expect him to give out his reasons for cam specs.
I know v6bird also, matter of fact I talk to him almost every day. Ask him his opinion of Bret.
Bret doesn't think he knows it all, but he does know enough to be one of the best in the country.

Nobody hits it out of the park on the first swing everytime. The biggest difference was his first swing was broadcast on national televeision more or less. I would call it a solid double, based on the fact that he gave the customer exactly what he wanted. I happen to know quite a bit about that whole situation, so I am not just spouting internet hearsay.

Bret Bauer eats rocks and ***** gunpowder; he knows his stuff and is not a Jelly Bean. I can tell you I have had very good expierences with him. Wait till the LSX race in October is over. Look at who the #1 qualifier is, and then speak negatively about Bret's work.
