That 427 may not make more peak power but it would make more power when not making boost and also make more across the curve. That’s why cars with more peak power get smoked by cars that have a well designed and thought out combination. They are set up to go , not to make a dyno number. Can be a substantial difference

I am curious why you think 9.5:1 compression is not good. I spent a lot of time researching every component of my build. I also spent a couple hours going through my build plan with one of the lead engineers of the COPO Camaro program.

I believe it will be in 950-1,000 FWHP neighborhood and should have the dependability to drive across the country w/o issue.

Talking it over a few beers Im not sure I have seen any COPO with a Blower Sporting a Compression ratio any less then 10.2.1.. Additionally they are all small Cube/liters.. Still curious why the lead engineer wouldn't implement his recommendations into the GM designs..

Your a pretty funny guy. You post that the blower has a hard time feeding anything over a 376 and when I post strokers doing it you comment of course the 427 will make more power.

I’m going to try to bring this back on to topic.

Nighthawk89 with the 10:1 compression what boost numbers should a person aim for? Have you calculated what your effective compression ratio will be at the desired boost level? What octane fuel will you be running full time?

COPO Camaro is purpose built, different vehicle and goals.

Exactly. These cars are built to run in specific NHRA Classes that have restrictions on HP, vehicles weight limit etc. Much different than a build for either street use or max power.

I think the easiest way to compare notes.... Fatal Posts his tire spun Dyno results and once my build is done I will post mine. How does that sound?

[Ajax2112]

Can you post your last dyno sheets? Stock? After first round of mods? Your present setup? And then after your present build? I would be more interested in seeing how much you have gained from each stage. I think that is more useful and would benefit the community better.


Can you post those sheets?

I will gladly post my numbers after I get it completed but my project is AWD, it is a GM hybrid. ��

Looking forward to this! Are you going to post it on any syty forums or anything?

I don’t post a lot but I occasionally do on the FB group. A lot of people think they should be left stock so I avoid the drama.

Oh I know, I have one of each and I’ve always said if I blow one up I’ll throw an LS in it haha. Good luck with the build!

Very cool! 👍

You are even funnier posting higher boost engine dyno runs and try to compare it to rwhp runs on less boost, add 15% to 20% drivetrain loss to your video engines and they don't make it to 800whp with more boost.

Thanks for proving the point that was made earlier, bigger engine, lower compression and higher boost making the same or less power than the stock cubes and compression using a TVS2300. Bigger cubes with lower compression would be better suited with Twin Turbo or a Centri to really show it's potential.

Maybe so, but not vey much with lowered compression. You do know the threads says highest Maggie HP/TQ
