So in a effort like everyone else to squeeze more go out of the little blasty i am thinking of shaving the head and having some bowl work done. What kinda pep or benefit am i gonna get from this? at what compression does the need for 91+ octane come in. I have a 55 gallon barrel of c16 here for my 240z but thought i would ask.
Compression vs Hp
- Thread starter Dude
- Start date
The best advice to offer is to contact one of the engine builders from this site, Ken OConnor racing, Flotek, Wildcard Racing or someone similar and discuss the options for head rechambering.
A lot of power can be tapped out of the blaster cylinder without bumping your compression up into race gas range but the entire engine really needs to be looked at as a whole to make sure you can extract maximum power out of your powerplant

Thanks for the one good response anyway. Yeah i have contacted a few. I think i am gonna throw the engine into my 3d modeling and run flow tests on the head and chamber design and see what i come up with. Also working on 3d modeling exhaust for best flow.
Porting of course is the best but i am looking for accurate R&D with flow numbers and such. I respect alot of these guys doing porting and i would love to get some of there products and actually run them threw a few programs and the like and run flow test's on them.

one thing on the the exhaust is your not necesserily looking for best flow, a 2stroke has to be specificly tuned for best resaults.
Indeed the dynamic flow/pulse wave on a 2 stroke are a lot different than a 4 stroke.
162 is good what does that put you at 10.5:1
However maxium flow in and out is still king to making power in any otto cycle. I wonder if alot of the big guys just have something that works from trial and error or because there is massive R&D with flow data to back a port shape.
When i port a rotary peripheral and bridge its from experience on what kinda bridge etc...

Sounds like you would like to do the modeling and testing as much as you would like more power.
I work in the automotive realm where a lot of R&D comes from the track. You can build for peak power on a dyno or you can build for peak performance. Many will argue but there is a difference.
What I mean by that is that you may use 3d modeling to build an engine to flow a certain way then go out an line up with an old timer who has been building these things for years and get your doors blown off.
If you do this modeling and such please post it I think it would be cool to look at.
