Anyone have a WR450 or other 450 Torque Curve?

[Spetsnazos]

I am in the process of doing some preliminary calculations on an engine decision and I am in need of a torque curve for a SAE tuned 450 engine.

I've searched the forums and came up empty handed.

Thanks again!

Learn the ways of google fu. Try "WR450 dyno".

I was actually looking for one thats tunned with a restrictor(FSAE specific).

But I will use the internet if nothing else is available http://fsae.com/groupee_common/emoticons/icon_smile.gif

Do some basic, steady state compressible flow calculations for the airflow required to make stock 450 power (call it ~45hp). You'll find that the restrictor should have very little effect (assuming the plenum volume is somewhat properly sized).

On the FSG site, you can find dyno results for all cars in 2008:

Delft was running a WR450 on E85, and I believe ETS Montreal had a WR450 as well but I'm not 100% sure.

Look at the Formula Student Germany Homepage. You get the curves @least from Delft I think.

Have fun with it!

Jasper is correct, ETS was running a WR450 in 2008.
