dynoed the car finally!!!!!!!!!!! 320/320 at 11 psi.

[farmerz24]

today i dynoed on a mustang dyno 320hp at 5500 320tq at 4500. 11 psi.

made 280/280 wheel at 9psi. stock internals, ported heads, milzy stage 1 cam, turbo headers, t3 82ar stage 3 exhaust, 60-1 compressor, 70mmtb, 3500 plenum.

in a 2000 56 spd cav.

what do you say? i guess i need more cam i can post the sheets here too if need be. also, bro's cobalt at 15 psi went 280 wheel hp at 7000 and 220 or so tq!

time for mroe cam i think i want to rev to 7.

Very cool Got a scan of the sheet? I would like to see the powerband. Is that the stage 1 turbo cam? I don't know if I have those specs written down or if they are posted yet.

How is the 70mm TB with boost as far as drivability?

Very nice numbers man! Those are some of the highest I've seen yet from a 3400. One of the turbo guys on gagt.com has been running 8psi but hasn't had it on the dyno yet and is still tuning it. I think he's planning to up the injectors again from 42#'s to 60#'s before upping the boost. That and he needs a bigger MAF 'cause it's close to maxing the signal. It will be interesting to see what kind of numbers he gets with the auto trans compared to yours.

Aaron, tell your buddy with the "Maxed out MAF" that in his programmer he can raise the fail limit to 32,000. Then from a scan of the fuel trims the MAF can be scaled to fuel the new #'s.(Remember to make a PID to cover the new scale all the way) It does work incredibly well!!

Had to add=(after checking) MAF can be moved to 32,767 Then tune WOT using the PE tables

[TurboGt]

Those are some impressive numbers!!!!! POST UP A SHEET!!!

I need to get off my ass and get my car tuned better, and hit up the dyno.

Did you ever run you car with the 3400 plenum? I am just wondering how much of a difference the 3500 made. Withe my new TB I will need to be upgrading soon.

[farmerz24]

3100 not 3400.... stock motor, v6ho ported heads, milzy stage 1 boost cam.

hp peaking at 5800 i guess i need more cam? or maybe my exhaust wheel is becoming a restriction? time for a gt35r and more boost.

70mm is great for driveability i made a variable rate throttle arm, so the first half or 3/4 of pedal travel is probably 50% or 40% throttle opening, then
on the last 1/4 it opens it right up.!!!

my torq is insane, same as the hp, but i was hoping for more as that guy with the remote mount dynoed 320hp 350tq at 12 psi the wheels no?

next year is a built 3400!

[MMGT1]

WOW, those are nice #'s for a 3100 man. HATS OFF TO YA"!

[farmerz24]

heres the graph.

mustang dyno 11psi.

[MidnightriderZ24]

the remote mount 3400 was at 10psi. i have yet to dyno and i have quiet a bit more done than he does. isnt that my old 3500 plenum and tb?? lets see pix!

[farmerz24]

yea, i think thats your old one, minus the egr mount.!

do it up, lets see you beat 320 on the mustang dyno!

No you can't. ALL GM maf's are set to max at 11,500Hz. They won't put out a signal higher than that. So once you hit that max you can be pulling in more air but the pcm won't see it so you run lean. What you have to do then is get a recalibrated MAF, or get a larger MAF. That in turn makes the Hz signal it puts out correspond to a different quantity of air, so you can pull in more air for a given signal before it hits max again. Then you go into the MAF table in the pcm and change the scale to match the output of your new MAF.

Just ran your mill through turbocalc and you are at the limit of a .82 turbine housing just before 5400 rpm and 11 psi which shows on the program 300 hp if calculated with an intercooler and 263 hp without. The intercooler reading is the one I would go by even if you don't have one because it is closer to your actual power output.

[farmerz24]

cool. so looks like its time for a t4 upgrade. im thinking a gt35r, but the question is what a/r in the t4? 80 or 60's? Im wanting to go 600 engine on this one and rev to 7. what do you guys think? 82 or 63?

[MMGT1]

No you can't. ALL GM maf's are set to max at 11,500Hz. They won't put out a signal higher than that. So once you hit that max you can be pulling in more air but the pcm won't see it so you run lean.

I don't care what those morons on the HPT site say. Those are the same guys who couldn't figure out how to tune the VE table. It doesn't matter if you raise the limit of the MAF in the pcm. The MAF won't put out a signal any higher than 11,500Hz so it won't do you any good. I don't know how else to explain that to make you understand. The DHP tuner doesn't even have the option to raise the maf limit because there's no point.
