Stock 7MGE Turbo'd Dyno run

[Devin LeBlanc]

Dyno'd my car and tuned it yesterday, I made 219WHP & 208 WTQ @ 9lbs of boost

Mods:

2.5 Inch exhaust
Driftmotion Front mount and 2.5 inch Hard pipes
HKS knockoff SSQV
Driftmotion NA-T oil line kit
ARP Head Bolts
Felpro Head Gasket

GTE Electronics
91 Pump Gas
Timing at 10 degree's
Stock NA Cams
Stock NA Pistons
N/A LSD Diff (Pulls hard off the line)
140,000 miles on original engine

1/4 mile next week, before when I was N/A all stock but exhaust I ran a 16.9 @ 83 hoping to bring that time down..

I was quite lean up top above 4000 RPM but was able to get the AFR at 11.5 at full boost.. We had to max the SAFC Neo out to +50 correction up at those RPM's I think my fuel filter is plugged so I just picked up a new one to replace im pretty sure its the original on the car now with 140k so we'll see what that does

Here are the videos:

Thanks

EDIT: This dyno graph is way low.. This run was in 2nd gear.. We will re do it in 3rd gear for a 1:1 ratio and also the torque converter doesn't fully lock up in 2nd gear.. So my numbers are off by about 60-70

Stock dp? Cant wait to finish mine.

Congrats on making it off the rollers alive Devin

 

[shaeff]

Very nice.

 

[Devin LeBlanc]

Thanks IJ, Cant wait to re dyno it again in 3rd with the torque converter locked..

Mecevans: That is the stock down pipe but with the catalytic converter cut out and a pipe welded in instead.. It has 1 high flow catalytic converter and 2.5 inch exhaust

Thanks Shaeff

Here is a pull today on the street basically spinning 1st and 2nd after re street tuning it with the new fuel filter in and the SAFC re initialized.. Something went wrong and wasn't giving correction but its fixed now and AFR holds steady in the low to mid 11's at all RPM ranges above 3000 at full boost

Once you're over 2500 the lockup isn't going to make much difference at all, with the PCS I always tuned it so it would unlock at WOT to save the converter clutch.

Is that a Harbor Freight Gauge I see!?

Stock wheels/tires?

Good job!

 

[Devin LeBlanc]

Yes it is.. Sorry lol we checked it with another auto meter gauge and its actually dead on accurate lol so it was worth the 14.00 I got it on sale for lol

I just changed the Injector resistor and fuel pump resistor to the turbo model and it made a big difference.. I boost a lb higher now.. I didn't think they were different so I swapped them anyways to see if there was a difference and wow..

Yes those are Sawblades on 225/50R16 Federal Ziex

 

[kikdurazz]

At +50 correction on the SAFC what the hell was the timing doing. Figure it woulda went boom with that much correction under boost.

 

[Devin LeBlanc]

I am pretty sure it is the fuel pump resistor causing my lean at high rpm problems.. I checked and the part numbers are different on them comparing a 88 turbo one to a 88 non turbo one.. We will log the AFR tomorrow with the new resistor installed and see how it does. No detonation and AFR's held rock solid at 11.3-11.6

 

[Devin LeBlanc]

Well after two days of extensive diagnosing I found out it was the SAFC causing my problems, unhooked it and here is the AFR log at 9 psi boost

 

[mecevans]

Any new dyno numbers?

 

[Devin LeBlanc]

Not yet, Haven't had time to dyno at our shop due to sema, now that thats over we will dyno it..
