Car Info
Year: 96
Engine Management: ViPec
Turbo: 6765
Intercooler: Innovative Tuning custom water/air
Meth Kit: none
Injectors: 2200cc
Intake/Inlet: 4" air filter on turbo for now
Headers: Innovative Tuning custom
Uppipe: Innovative Tuning custom
Downpipe: Innovative Tuning custom
CBE: Innovative Tuning custom aluminum
Other Power Mods: OEM Subaru 2.5L shortblock straight out of the box from Subaru, never taken apart. The rest of the car isn't stock.


I'm just having a little fun with my time attack build. I saw the Subaru stock shortblock drag record wasn't flattering and I figured I'd make some power on a stock shortblock and see what my time attack car can do at the strip while we're slowly making progress on aero and other road racing related parts.

I stopped at 21 psi and pretty conservative timing for E85 because I don't want to push the stock shortblock to the breaking point.

When I'm done horsing around with the stock shortblock we'll put one of our built shortblocks in and I'm expecting 650-700 wheel HP at ~30 psi.

Nice, I'd like to see that turbo turned up and see what it can really do. How is the spool on the 67? I'm putting the 6466 on my hybrid build.

Btw what is the highest stock block hp anyone know?

Thanks folks.

Spoolinred the pink line and scale on the right of the graph is boost. It would spool sooner with aggressive boost control settings, but I just set a flat duty cycle for now.

I'd rather not know what the stock block HP record is because I'll probably do something silly and try to break it.

wagonator I'm expecting 650-700 wheel HP at 30 psi based two similar setups I've tuned before.

Very nice Mike!!

I have my 6766 in my backpack as we speak traveling home from P&L. I see we have the same basic idea, I have a stock block with some headgames heads going in my GC. Trying to see how far it can go in a lite weight. The XT went 108 1/8th with the stock block @ 3500lbs. So I can imagine trapping in the 140s will happen.

Good luck!

Sounds good. I think I'd be faster with a 6262 especially since I'm not revving it out or flat shifting, but the 6765 is what I run and I'm not swapping it for this. When the built shortblock goes in the 6765 will be loving life.

Nice job! It's the Torque mainly that kills the Liners, etc. if you keep Torque below the danger level (+/- 450-500lb/ft) you can make plenty of power without the cylinder pressures becoming too large.

We have also gotten some high power figures out of stock blocks and to do so we have used a tapered boost (low to high) profile. I think you can ramp the boost up from 6000 rpm going to redline to lift the torque there and power figures accordingly.

Anyways... it's a good result you have there already. More boost at redline would just be icing on the cake

Jasper.

We've run a lot more power than this on stock liners so I'm not worried about them.

I won't rev it out and I'm not loading the rods heavily at low RPMs so I think they'll hang in there, but I don't know if the hardware will.

My chief concern is the tight ring end gaps Subaru uses and my second biggest concern is the tight piston piston to wall clearance. I've done what I can to reduce cylinder heat within reason, but at more than double stock power, heat will be well beyond what Subaru intended.

I took it to the track today. Unfortunately I blew an axle the first time I powered out of a corner on my first lap. It whipped around and hammered the rear subframe so we have some repairs to make. We'll get it on track soon.
