Subaru Stars Cosworth / APS TSR70 - 540WHP

Dyno graph -




Some interesting points that will hopefully answer questions before they're asked -

* MZM's dyno is a true heartbreaker and reads very low. Do I care? Heck no, the car consistently runs great numbers at the track and it's MPH is a true indicator of the real power it's making. We'll see exactly what it runs as soon as the weather and my schedule permit.

* For people that like to play the numbers game, Mohammad mentioned that a typical DynoJet reads 20% higher than his Mustang dyno, so that 540whp would be 648whp on a DynoJet.

* The car has already ran 11.33 at 127.92mph on a 434whp tune, and that was leaving the line at an idle. It's going to be real interesting to see what the car runs with an additional 100 horsepower and not having to short shift at 7000rpm.

* Fuel used was Phillips TrackTek 105 octane unleaded, no alcohol, no methanol, no water, etc - just motor and turbo.

* Temperature was 94 degrees and humidity was 95%.

* This car peaked at 205whp stock on this dyno (at 6000rpm, if I remember correctly) - it's now making that much power at around 3300-3400rpm.


Major components of the car -

* APS TSR70 turbo
* APS 3.5 inch exhaust
* APS DR725 front mount intercooler
* Cosworth block, heads, cams
* HKS 1000cc fuel injectors
* HKS F-Con V Pro engine management
* MZM awesome tune

They're the Cosworth 278/274 cams and the idle is right around 1000rpm with very little oscillation.

It's the billet crank. Cosworth doesn't offer sleeved blocks any longer.

The exterior/interior pictures in D-Sport magazine are actually from November of 2006. It took them that long to actually print the article on the car...

They have lots of things to consider in each issue. They can only do so many STi's, only so many cars from Texas, only so many cars from the same shop, and on and on... So it's understandable... MZM has had 4 cars featured this year...

Hi Stick! The 93 octane tune is at 19psi and the 105 octane tune is at 27psi. It can take more but it's already capable of breaking drivetrain parts as it is.

A couple of under hood shots for the people who PM'ed about it. Your typical crowded Subaru engine bay.

I know the limiting factor back when you made 434WHP was the small hot side. So what did APS did for you? I assume a bigger hotside...

Numbers look awesome! Should be much faster. Congrats awesome car.

Congradulation awesome numbers.. how do you like the SR70 APS kit. I have the same set-up and will be installing after I achieve my goals on the stocker. People where saying the UR 35r kit is better and other really like the SR 70 kit. What is your experience between both kits.
