A comparison of my stock baseline horsepower run vs the TechWorks mods.

A gain of 34.16hp around the same boost psi.

The torque graph.

A gain of 26.47lb-ft of torque at about the same boost pressure.

Future: To address fuel issues, get stronger clutch and increase boost.

Car: 1989 2.7ltr Subaru XT6 (AWD/Autotranny)
Place: Xotic Motorsports
Dyno: Dynojet

Car has bad tranny. It's very weak. I can't describe some of the noises/shakes/shifts that come from that thing. So, I couldn't dyno in AWD. Ever since learning the tranny was weak, I've been dynoing this car in FWD mode (put 10 amp fuse in place in the engine bay). So all dyno runs that have been performed previously and up to now is in FWD mode.

All dynos are from the bottom of first gear and stopped when it shifts out of 3rd. I only show 3rd gear hp/torque results to prevent confusion. I do like knowing what's going on power wise in all gears though.

The dyno plot you'll be looking at is a comparison of 3 different dyno session.

The blue line stock dyno run.

The green line is when I had a 2.25" cat back exhaust put on with a 2.25" Dynomax Ultra Flow SS muffler.

The red line is the 2.25" catback with the addition of a JC Sports intake and a ProECM pulley added.

Max hp I now have is 120hp vs 113hp with the Dynomax muffler vs 112hp. This doesn't tell the whole tale of the tape. As power drops off with the stock setup, there is a fat gain with the intake/exhaust/pulley combo. I picked 5600rpm in the graph to demonstrate the difference in hp. Notice where at 5600rpm I have 120hp while stock I only had 100hp. That's great!

Torque graph!

I'm not going to speak about the max torque since the result is a bit skewed. When the car shifts from 2nd gear to 3rd gear, it's right at torque peak and a part of the shift shows up on the beginning of the graph. However, I picked the same point in this graph (5600rpm) as the hp graph to show the gains made. While stock the XT6 only made 93lb-ft of torque at 5600rpm, the intake/exhaust/pulley combo shows 112lb-ft of torque. That's a gain of 19lb-ft of torque. Nice! And it seems that it pretty much tries to keep this gain throughout the powerband.

So there you have it. If you plan on modifying your XT6, a 3" intake tube, a ProECM pulley (2lbs lighter than stock) and a 2.25" exhaust can really work for you as a combo together. Stock hp and torque figures are 145hp/156lb-ft or torque. So theoretically, you can say I'm making approximately 165hp/175lb-ft of torque.

More information on the mods I posted can be found in some of my other posts.

Recommendation for future posts:

If known, please post recorded outside temperature when your dyno session took place. Dynos can only correct against altitude and humidity.
Especially with turboed cars, high temps kill power.

might help to compare setups from coast to coast.

I did this dyno with one plug accidentally not plugged onto the sparkplug, but rather just sitting on top of the sparkplug so it was firing just because it was close enough to ark and fire. Also, I replaced the fuel tank filter after this dyno run and fuel pressure jumped 10+ psi.

Exclamation Cusco Center Diff: Kicks Ass on street... SUCKS ASS on Dyno

Well we attempted to dyno my car today on the DynaPack.
Attempted being the key word. We didn't exhaust all our resources, but we ran out of time.

I never got to punch it.... the dyno and drivetrain had some CRAZY oscillations!!

One sheet I was able to get all the way to 1/2 throttle for 240whp.
However, This dyno sheet says it all:

1993 EJ22T Block with stock internals
SOHC with COBB Cams and TWE high lift springs
Ludespeed Stage III Turbo Kit
Hydra Nemesis EMS
JDM STi Gearset
Steel 3-4 Shift Fork
Cusco Tarmac Gear Center Diff
Cusco RS 1.5way Rear LSD
Cryogenically treated R&P
etc etc etc...

So basically I need a four wheel roller dyno for this to work.

Thumbs up Cobb Stage 2 Version 1.19

I need to get the 1.22 revision eventually, but I was quite happy with what the dyno showed. I think I'm right around where Cobb advertises their crank HP to be at for 93 octane. Basically 225 HP to the wheel and 217 lb. of torque - IIRC, the boost was at ~16.5 psi. Achieved these number on my fifth run. First run started at 209 HP. I believe it was determined that I was a bit on the lean side, but that may just because Cobb is more on the conservative side and tuned at a higher altitude?

My main mods are MRT TBE, Helix Uppipe, Perrin Pulley, Samce I/C hoses, Deadbolt's P&P Turbo.
