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.

....
damn...nice

Thanks for making those runs with the water injection ;)

All over again I am envious of someone elses setup.

You are a madman! Awsome numbers, I hope that you'll be posting over at m.net for some entertainment! :)

wow that much power on 330cc injectors? bad ass buddy, awesome!

No problem son, check your PM's.

nice! :bigtu:

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:)

still that much power with only a AFPR and Bipes is pretty damn good no matter how much pressure

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.

wheres the graph dude?! nice numbers!!!

but think about what he could make with a perfectly flat AFR...

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?

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.

Mark

Dammit i'll be there next time for sure Andy gotta get brian my car today and then we can see what the dammage is i realy wanted to go but oh well shit happens.

Like i said before if you need some methanol once you get that far let me know. :bigtu:

absolutely awesome figures. bet your well happy with that!

Power i dream of!

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.

You are everything that I aspire to be...:dancegay:

Andy,

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

That's the hotness. Nice job!

nah, I dont have it hooked up yet. WOT is gonna kill me.

I'm looking at this nitrous kit I have sitting in the house... thinking... Do I?

Mark

PS - It's a 75 shot.

What are you waiting for?:bigtu:

dude, fucking do it. I have been pondering the same thing...:eek5:

andy, are you sad you can't post "300 whp" in your sig?

if he converts to dynojet he could.

:tears: YES:crx:

That's awesome power. If you were on a "cheater" dyno, it would be well over 300.

Now get a standalone in that thing!

YES!! puleeze dyno your's too. I would love to see what other GT3271 setups are putting down:) How did 21psi feel :eek:

I broke the damn manifold on the Dyno LMAO.

264 ft/lbs torque, 296 RWHP.

Two very different paths to nearly the same power.

Mark

Where you at 12 psi or 15+

Somewhere between 17-18 PSI.

nice mark! I bet when you get that manifold fixed youll make more power since you are going to see spoolup much faster when flames arent shooting out the manifold;)

nice numbers

I've dyno'ed quite a few rising rate setups where the injectors would lock open, or at least that is the only explanation that I could come up with. Going 40+ or 40- on an AFC would have absolutely no effect on the AFs. The ECU might be calling for 5% or 85% duty cycle but the injectors where at the mercy of the fuel pressure.

I've taken 330cc injectors to 240whp on a regular 1:1 setup, so 290-ish isn't hard to swallow.

I'm going to preface this comment with the following: I've been out of the tuning thing for a few years so my experiences are a little out of date.

This is something that I did years ago taking advantage of knowing multiple people that ran dynoshops, I'm a little hazy on the exact figures but the trend is more relevant. We dyno'ed a car on an in ground dynojet and drove over to a shop with a Mustang dyno. From what we saw the Mustang dyno came up with numbers 15% lower, or whatever the hell the amount was, but when we ran the Mustang in its so called dynojet emulation mode it made almost the exact amount MORE than the dynojet. And then we headed BACK to the dynojet and backed up the earlier figures with about a 1% deviation.

My only point to this is to say that dynos with user accessible variables produce plots that are only useful in comparison to other graphs to whatever degree that you trust the source. And I'm not limiting that statement to other types even. An unscrupulous tuner could monkey round with settings from one run to the next to bilk a customer.
