Interesting choice on the fuel system. Can you provide more info on you decision to go that way?
Happy boosting  |
Thanks Albertomg.... my reasoning for going with the newest model RX-8 injectors was that Paul Yaw of Yawpower here in Phoenix has done extensive flow testing of various injectors on the market. He believes that these injectors provide some of the best atomization results of any that he's tested. My choice on secondaries was the result of choosing to go with the Ground X LIM. I think the idea of equal length runners will make a difference on better balancing my engine temps from front to rear housings, however I have yet to take any data to substantiate this. Again, Paul's 1000 cc secondaries provide superior atomization, so in theory I should be able to run 4 secondary injectors with my Power FC at lower duty cycles, and without the need for aftermarket resistors. Not sure what duty cycle Tony hit while making the 439 RWHP pull, however I'm confident that I have more than enough fuel to support another 100 HP. I'll check with him on those duty cycle numbers tomorrow and report back.
Tony at UMS has tuned 100s if not 1000s of cars, and he was truly impressed with the injector performance. His comment to Glen was "Man, I've got to have a set of those." I think that speaks volumes.
