Wondering how much timing/boost you've run.
good question, just getting started with a 10* DRCE2 procharged combo, would like to hear experience other than "it won't work".
I've been running my 12° combo for over a year now. Roots blown, haven't gone over 30# boost and 24° timing. So far so good, the plugs show it could stand a little more timing. Just wondering if anyone else has experience with a combo like this...…...
I have seen 47 lbs of boost with a procharger. Timing wise depending on weather 24-27 degrees. There is a bunch left in it.
Sean, I wasn't too concerned about going with more boost, pretty sure it can handle more, mainly the timing with these small chamber heads......do you run a 12° combo?
72cc chamber it was opened up from 56cc. 2&8 needed timing taken away they will nip the plugs. I do not think I would push it anymore then 30 degrees. I do not know your complete combo either.
My heads are at 60cc, 11.7 CR
I run a 14* 387 combo. 49cc heads. 10.5:1, 29* in the mag, 14# (index car, can't go faster than 7.600)
You have a racepak? egt's?
I do, but I go by the plugs, don't hold much faith in EGT's...…………….
I too read plugs. no data recorder
It all ties into each other. Who did your fuel system? I would want to see the fuel curve and what is happening in each cylinder. How deep is the dish on your piston? 2.400 or 2.45 valve?
