Seen a couple of high compression boosted builds on Honda-Tech, I am a bit baffled as to how these run without exploding. I see some guys wanting to run 15psi and a 14:1 CR, is this even possible?
Garrett have a small article on compression ratios, but I wouldn't have thought it was possible to run that high a CR without blowing a HG unless you were running 100+ octane and retarded ignition timing?
Although I'm sure someone with a better knowledge will correct me
Currently reading through it all to see if there is some explanation but I really cannot see how you can have that sort of compression with that level of boost.
It's fine... all you need is the octane to backup the compression. There are loads of FI race engine's out there running what we consider as "high compression". It's all about octane...
It's actually the opposite to "pokey " lol. I think it's energy content is around 30% less compared to petrol. BUT the use of high compression improves the engine's efficiency which allows you to get that 30% back in some cases.
