'07 FXT 4EAT
VF48 with STi TMIC
Grimmspeed PnP EMs
MadDad bellmouth catted DP
MadDad 3-inch Whisper TB
Walbro 342
100% stock intake track
Open source tune
241 WHP/326 torque on Mustang dyno in August '09
19.3 PSI (14.3 at redline)
Dyno graph

Observations

1. It looks like I have the lowest WHP of the group so far (for what ever that is worth)
2. Lots of torque, but with a sharp peak at 3200 RPM
3. Car feels tronger than the above numbers indicate

Getting back on the dyno in on 4/10/2010 with new Perrin TMIC, Samco turbo inlet/afterMAF hose, GS AOS, turbo blanket (all already installed) and possibly a GS EBCS. Along with cooler air I hope to see some improvement in my no-better-than-stock-STi WHP numbers.

turbo inlet/afterMAF why? tuner recommendation? stock torn during VF install?

341-346wtq on a Mustang dyno with VF/Perrin is overly optimistic, must be a newer Mustang friendly dyno.
what psi is the target for the second tune to get those numbers? Please post dyno charts.

I will be very happy if I reach 325wtq with my set-up (see signature) at 20psi.

I just like modding, especially the those mods that are a real PITA to do! But mostly I didn't like the flimsy OEM inlet connection to the turbo and would prefer something a little more substantial.

This is the Mustang dyno at EFI Logics in CT. From what I can see, it reads pretty low. I am expecting a bump in WHP, hopefully to around 260. I'm not expecting much change in torque.

dyno charts would be nice, but dont get hung up on the numbers. every dyno reads differently, so its basically retarded to compare unless you were on the same dyno/same day...

While Im no expert, but from what I have read, corrected numbers are suppose to make it level from location to location. My tuner doesnt give out corrected numbers though.

Damns!!! Nice results..who tuned?

91 or 93? I am thinking p&p mani/hi-flow x-pipe and injectors would have complimented your tune, but otherwise it is a hoot to drive!! 4eat FTW!:discomonkey:

We have 92 in Oregon. Bobby Wintrode at Performance Race Engineering was the tuner - also tuned Sea-Scooby, Smooth, & wakeabyss.

Agreed about the exhaust mani's and injectors. If I go that route, I'll probably do a larger turbo and TMIC (or FMIC) at the same time. And that's partially why I didn't do injectors - it starts you down a slippery slope called "where the heck does this road end?!":biggrin:

There is no end!!!!

I figured you went to PRE.. but just czecking..

18psi.& 92... seems quite conservative. I really think opening up bottom end & swapping to STI mani. will give you a bit better high-end response.

BTW....I spiked 22.3 psi today....random pull on a cool day with 3 passsengers.....hmmmm.??

Nice numbers guys. Anyone running supporting mods for their trannys though...like Valve Body upgrade, High Stall TC, Transmission Oil Cooler? If so, where's the best place to source/install these parts? If not, then is this not necessary?
