Does anyone know where I can find the HP / Torque curves for a stock EG 33? I have just fitted on into a jetboat and want to know what power i'm producing at 3200rpm.

 

TIA.

I've not any charts, but I'm sure at 3200 rpm you're a long way from peak power output. You are most likely close to peak torque at 3200 rpm, however. Have a look around the web...there should be a number of SVX enthusiast sites.

 

Mind posting some pictures of this monster?

Here's a pic.

There's a fair bit of BS to wade through but a heap of pics too. :D

 

The blue paint looks great!

 

I see you've no pulley at the (front) end of the crankshaft. How are you driving your accessories?

 

Is that the stock intake manifold?

Intake is stock, the only accessory req'd for the jet is the alternater which is mounted on the rear of the engine. This allows more room for the back seat in the boat.

Are the parasitic losses due to friction in the drivetrain _that_ high, or does the dyno. "read low"?

 

Makes me wonder how much (little) my Legacy puts to the ground.

You loose a fair amount through the AWD.....however that dyno does seem a little low. It can depend on the type of dyno that was used as well.

awd and the tranny in general suck up at least 40% the SVXs power.

sad but true.

40%... i'm sure glad i'm not using any transmission... or A/C... or power steer!

 

Also with an aftermarket ECU I could be developing more than the manufacturers power rating?? :D

yeah, I'd say you'll do a lot better with an aftermarket ECU, since you can tune it for performance & to run right, rather then for emissions.

176 whp is not that bad with a auto AWD, a stock Mk3 supra turbo 5spd (230 horse) will put out around 195 whp.

 

I gtec pro dynoed my dads legacy, ej18 put out a amazing 70 whp.:D
