Not to mention on the crappy mustang dyno.
I know, I'd be jealous if I wasnt running on pump gas. LOL.

Andy you are a MADMAN! Love that about your setup. It's the ghettocharger of engine management. LOL.

yes true, drop the BFSC numbers a tad to .5 and it's right on 331cc at 85%

Because 10.5 AFR's are WAY too rich, especially with 110 octane fuel. I could get away with 12.0 AFR's on 110 octane easily and most likely gain about 15whp after 5000rpm.

LOL yeah, I have ghettocharger EMS, and you have TEC III-R. I have a GT turbo and you have a Chinacharger. I think you will make a lot of power when you dyno. If you can utilize your extra rpms and hold torque deep into the rpms youll make a nice amount of hp not to mention a fat powerband.

.5 is a very efficient motor. There's no way a 10:1 stock ecu turbo car at WOT is running that efficient. I think that injector duty cycle is increased--not because the ecu is capable of doing so--but because 115psi (more than double design) of fuel in the rail is hard to squeeze off.

The guy running the dyno where I went asked me if the injectors go static on wot. If they do, that explains why I couldn't lean out my fuel curve.

Honestly it doesnt feel fast to me anymore. Thats why when I go back next time its with a standalone. Ill be running over 20psi at that point too.

true. who knows...he does have a built 1.8. RC calcs get you in the ballpark at least.

well I dont know honestly. I understand where you are coming from thinking that at pressures that high the injectors will just lock open and dump fuel. I am still sticking with the stock ecu keeping duty cycle under control even at higher pressures. if you look at any stock ecu dyno they all go pig rich from 5000rpm on up. Even the stock car is that way. Leaning out the fuel curve in the upper rpms with the shitty management I have is impossible, I can only do so much.

Andy,

You were using water injection?
What size nozzle and what pump psi?
50/50 water/meth mix?
