Compression and stroke are to blame, I noticed the hp fell off before 6000. I be that changes with less compression.

I didn't get greedy.. we just got surprised with a really thin head gasket from RHS. Hoped it would be fine with the overlap and that dynamic would be in a sweet spot. Oh well.
Could put in the bigger cam and drop dynamic, but I don't want the bigger cam. This is the first engine I've ever "designed" that came up needing more than 91 octane, but it happens.
The HP fell before 6000 instead of after (like on the engine dyno) because the 90mm TB is starving the engine of air at that level. The 102mm should help with that.
Only looking to drop it 4/10ths of a point.. we are just outside the 91 octane range. To be honest if I lived in a 93 octane state without all the crap additives we have here in CA I would most likely be fine. Here the next step from 91 is 100.. which sucks.
Anyways, just a temp problem that can be fixed.. for now I will enjoy the sweet smeels eminating from my tailpipes.. :) |
