Whats Your Timing Set At? Are You Sure Your A/f Ratio Graph Is Right? Thats Is Extremely Low..... Wait Are You An Auto Or 5spd?

timing is at 20 degrees.
af kinda sucks as it was leaning out under boost.
my emanage crapped out so we couldnt add fuel, but when it was working and when we added fuel the power only went up.
it is a 5spd car.

Cameron Is An Idiot.... The Only Way You Can Get 350hp With The Stock Turbo Is If You Did Every Bolt-on Plus Did A Full-race Head Work And Built Up The Block. Basically The Turbo Would Be Just Adding Alittle Power To The Emensive Static Power.

i second the he's an idiot part... lol 350hp with stock turbo, give me a break. You cant even get that with the rb25's stock turbo...

a word of advice, NEVER LISTEN TO CAMERON, he's a salesman, and will do anything and everything to gain you as a customer, and after he sells you his product, he will treat you like shit.

Man you really need to smooth out that AF it is all over the place I have never seen one that bad. Do you know what kind of load they were running? Not bad though just get thoes Af's right and you should be good...Stubby
 
#13 ·
well jack (the guy who owns p1 and was doing the tuning) didnt want to take it past 6k as the afr's were getting pretty high.
i dunno what the deal with the afrs are tho.
all i do know is that when we started putting in more fuel with the emanage we were begining to make more power and better afrs.
he wanted to get the afr's into 12.5 or so under boost so it wouldnt be leaning out.
but my emanage seemingly died on the dyno for reasons unknown and so did my e-01.
now i have to remove all the emanage crap and send it in to greddy to have them look at it, as it goes right now the emanage claims it has no firmware.

you claim that the stock boost is 10psi but it really is 6psi, are you running a boost controller?
 
Save
#15 ·
6psi where did you get that??? Mine ran 10 right out of the box. I know of a couple other guys that have it set at 10. Also if your tranny is broke us a KA trannie...Stubby
 
#16 ·
the gage in my car reads 6psi I will look into that though thanks for the info on the tranny

#17 ·
stock boost is 10psi, you have a leak or a bad guage. you also my be reading manifold pressure which is lower than turbo prssure.
 
Save
#18 ·
definately 10 psi.
i did have my e-01 setup to hold boost at 10 psi so it would be solid all across.
unfortunatly that broke too so that didnt work out too well ethier.
also if you are using the rb cluster then the gauge is in mm/hg not psi.
700mm/hg is about 14psi.

Mustang dynos typically read low compared to a dynojet dyno. Plus you can set mustangs up in a variety of ways. It's hard to really say what type of numbers he is pushing on another dyno. To bad it was not a dynojet. Those seem to be the ones everyone is used to. Still, I would guess a little over 200whp with that setup on a dynojet.

well a mustang dyno is a loaded dyno vs a dynojet which is an intertia dyno.
this means that the dyno takes into account the car weight, temp, barometric pressure, and uses these factors to simulate road condtions.
so even tho it reads lower its an accuate number vs a dynojet that doesnt load the rollers.
besides i was happy with the #'s as it was what i expected.
im in the process of pulling the emanage and the e-01 out of the car so i can ship them back to greddy and have the techs look at it.
once those are done it will go back up on the dyno for another run and tune.
after that its going to be a fmic upgrade and one of the gt series turbos.
i already have 550cc injectors, a aquamist 2d to go into the car; so making power and having it being a street car are very fesable with this motor.

I was not bashing just educating a bit about the numbers not being comparable to the dyno most people use.

completely understandable.
personaly i think that dynojets are overrated.
i would rather have my car put out a lower number on an accurate dyno then a higher number on a dyno that just spins.
each to his own tho.

hmmm,well according to Night7 you can..
Quote: Now, as far as power goes, The RB20DET pushes up to 350 easily with the stock turbo, the RB25DET pushes easily to 400 with the stock turbo, and the RB26DETT pushes up to 500 with the stock turbos.

So wheres this infamous 350hp he claims with Stock turbo...

This post was made about 2 years ago when I was first introduced to RB's...I relayed information that was told to me...

RB20DET with port and polish, 5 angle valve job, stock turbo, new turbo manifold, intake, dp, exhaust, plugs, custom driveshaft, injectors...could probably see 350hp...to the flywheel...figuring in a 15% loss of power through the drivetrain, that would be about 300 to the wheels.

Now I'm an idiot, but Christian is the one who says that RB20's stock push about 210 to the wheels...and that they actually have about 230bhp...despite what Nissan regulated em at....and EVERY dyno he sees on a RB20DET he thinks is low...but when you actually look at the drivetrain loss etc... the numbers are right on.
