My RX7SP build up

RICE RACING · 02-16-2010, 09:09 PM

Tested the compression of the engine after 1800km and its good for a rotary at around ~122psi @ 250rpm (front and rear rotor same) cranking speed. Will keep an eye over this long term.

I changed the porting specification (compared to pictures posted, ports are stock) to give the engine much more mid range power and not concentrate on top end power so much, it is quite fast on road despite relative lower levels of peak power. I am projecting it will have a honest 480bhp to 500bhp (at the higher 1.4 boost setting) but will see what happens when I get around to testing this.
