what kinda of hp / trq numbers can you make with them

I tired seaching but cant match na pp bp

 

Usually around 400-500RWHP i believe...

The problem with a 20B PP or BP is that with the stock E-Shaft you don't want to spin over like 8K.. so a PP or BP doesn't really match the engine.

apparently the pp 20b's do about 420hp. and it would also have 300+lbsft of torque.

ah, but how long do they last at those levels?

 

with no turbo? forever

mike

 

Unless you spin it up to 9-10K where the power is. And you would also want to use carbon seals which only last ~20K miles..


With iron seal only spining it up to 8K with good maintainance it will last forever though.

The GTO PP NA 20B's made 450-475bhp at the flywheel, and they lasted just fine throughout the 24hr races.

FYI Mazda Motorsports only sells the regular 20B eccentric shaft now, and it has been working just fine at the track. Also, the Ianetti seals last a very long time, and I know of at least one professional race team which re-uses them for rebuilds.

 

we had a chance to talk to koby at some length last year, and he said the lemans engine could have gone another 24hrs

I been woundering about this.. thanks for the good infor guys


btw
dude a 48 hour race would rock!!!

 

Apex seal life in an N/A is mainly a function of the RPMs used. The LeMans race was done primarily at lower RPM, in an effort to extract maximum economy from the engine.
