Default went to the dyno today....

( Pictures to come )

I finally made it to the dyno today. I did 3 runs one at 14psi, one at 15psi and one at 16psi. It was warm ( 66*) and humid outside today since we are having unseasonably warm weather but its better than dynoing in the middle of the summer heat. Also this was on a mustang dyno and not a Dynojet so numbers may be slightly lower. Ok so here is the power I made....

13-14psi = 264.4hp 241.8tq
15-15.5psi = 283.4hp 266.9tq
16psi = 294.3hp 270tq

AFR's were never more lean than 12.5 at ANY point during these runs. I was around 11.5-12.0 up to 4k, then I had a little lean 12.3-12.5 lean spike @ 4300 ( full boost ). After 4500 AFR's dropped all the way down to 10.5 and stayed there. I was losing power due to the overwhelming richness up top. I cant wait to get a standalone so I can lean it out up top. I was running 110 octane fuel just as a precaution as well. Overall I am happy with the numbers. I am waiting on the pics to be emailed to me so they will be up shortly.

Say hello to 115psi of fuel pressure.

At 115psi that's got to be on the verge of boom Well done none the less.

I'm begining to wonder if the RC Engineering calculations aren't a little cautious.

Been like that for 4 years... I would say they will be fine

WOAH NOW WAIT A MINUTE! You are making that much power with only an AFPR and Bipes?!

Not to mention on the crappy mustang dyno.

I wouldnt call the mustang dyno "crappy" I think its a better dyno personally. Sure its numbers are a little lower. But it offers a more realistic power level, some dynojets are inflated a little I think. Yeah, I have a Bipes, AFPR setup. I just know the ins and outs of it. I can get the most out of what I have.

OK so Im waiting on an email so I can have betetr dyno charts but here are the plots for now. As you can see torque drops off in the upper rpms. I need to lean it out up top and I need a better intake manifold.

well if he's pushing the duty cycle to .94-.97 or so it's plausible.

I dont think the duty % is that high since the stock ecu is still controlling the injectors the duty cycle is whatever the stock 1.6L ecu allows...not sure what it is but would guess its not past .85.

With what we've seen on the 1.8 injectors and now with the 330's it's obvious that the numbers from RC have a lot of safety built into them.

What is interesting is that a lot of the experts say that you can't get this kind of power with a stock ECU. Guess the bandaids work.

Why lean out the mixture? Why not bump the timing up instead, that'll give you more power. Or doesn't the Bipes give you enough control?
