Efficiency graphs

mandarinvx

I don't suppose anyone knows where I could find efficiency graphs for the SCs; preferably both the GM and the Harrop

Annoyingly I'm sure I've seen one in the last couple of weeks, but for the life of me can't find it anywhere

They are on the Eaton website

The link is dead 🙁

I have emailed Harrop, I'll send an email to Eaton too 🙂

All I really need is the nin/max recommended displacement figures for both

Works for me, although I've got a better site for maps on my laptop, but currently at the GF's parents

What do you mean min max displacements? roots turbo chargers are fixed displacment to calculate how much boost they'll provide there's an equation using the engine displacment and the valve overlap again I can dig it out when I get back home.

The site wont let me see anything other than PERFORMANCE MAPS title in blue at the top notsure.gif

I was hoping to find enough info to see whether the Harrop can be run with a larger dia pulley to give similar power (ie rod safe) to the standard GM unit in stage 2 guise

Presumably there will be a point where the efficiency drops off and power / torque suffer dunno..

Then again, the standard unit is run at _200bhp standard, so maybe the Harrop would be fine...

For the benefit of future searchers, Harrop got back to me:
