Subaru alternators are good to well over 7500rpm before they get cranky... as for the power steering, that's an unknown factor. It shouldn't be too hard to use a pump off an STi and convert the rack as well. The pump bolts up to the block in essentially the same fashion as the EJ series engines, it shouldn't be too difficult to modify or refabricate the brackets.
Man, I love this bench racing stuff. All I need now is a lawn chair and a cooler full of beer!

Porter,
Thanks for the thoughts. Seems to me I read some threads a while back that stated that the heads and intake manifold were already fairly well port matched. Any thoughts on what size injectors that would be straight bolt in jobs and wouldn't require remapping the ECU? Do you know of anyone who's offering ECU tuning for the SVX? The MSD system that has been the subject of a recent thread looks interesting, but for $400 I'd like to see some dyno-validated performance increase first (especially since I don't see a turbo or supercharger in my future plans). Thanks again. -Bill

hmm.... truth remains. you never know exactly what has been done to make an awesome machine like that. i've no doubt no 3.3 svx can reach 500hp without fi, but something a little lower may be acheivable for a master tech with unlimited subaru resource.
think perhaps they rebuilt the engine and the rest of the car for the sole purpose of this achievement.

Dude. It cannot be done. No way, no how. 500hp out of a naturally aspirated 3.3 liter h6 is impossible. We'll even say it redlines at 7.5k just for fun: 500hp / (7.5 X 3.3)= Mep of 20.2 For comparison: McLaren F1 - 13.70 Honda S2000 - 13.33 Suzuki GSX-R600 - 13.22 This is why people view you as an idiot, and why we don't believe that your SVX runs 14s. - Rob

Let's think about the Porsche 911 GT3 for a moment, which is FAR from being the most highly tuned vehicle of its kind.
Its naturally aspirated 3.6L flat six makes 380hp@7400rpm, and 285lb/ft of torque at 5000rpm. Thus I ask... why continue to moan about MEP? I don't consider it relevant. Also, this 500hp number being thrown around seems somewhat silly. If there is a 500hp SVX in existence, it is certainly forced induction. Why do I think so? Because Subaru's SPECIALTY is high specific output turbocharged horizontally opposed motors. Their core competency does not include building high horsepower naturally aspirated motors, nor would they spend money on development time for one when a turbo version is easier to build and far cheaper. I am (and have been) responding to the ludicrous assertion by Rob and several other parties that 300+hp naturally aspirated out of an SVX motor is unreasonable. I stand by my position that it is not unreasonable. RPM limits and octane are the first two things to be cast aside in the search for power.

If you have someone come onto an SVX board and mention a 500hp 3.3 liter naturally aspirated engine, EVEN IF it had a redline of 7.5k it would STILL be impossible. So I think it's a good BS Detector. Quote:
Also, you never mentioned raising the redline until I called you on it. - Rob

Huck, do you have a spare pump I can experiment with? Doug

800/(9x6.2)=14.33 That even kicks McLaren's ass. Nobody tunes an engine like Americans can. Even on primative 2-valve pushrod engines! :-D

I think Colin (MontyPython) has a spare, that you might talk him out of. I'm sure it'd work on the SVX since it needs a digital Speedo signal...which the SVX has...to adjust the amount of assist.

It's also obvious, to me, that Porter knows what he's talking about. Neither of you are complete idiots, but you're the only person who's acting like one. Let's have a reasonable discussion, back and forth, without the name-calling and flaming. There is simply no reason why we can't discuss this without tempers flaring.
