Domestic Vs Import Dyno Day

[sky30]

Here is a great example of what you can do with a 3 litre RB series engine if you set it up and tune it correctly across the whole rpm spectrum, optimising for Mean Best Torque.

The interest to be taken away here is not in the 652rwkw (875rwhp) but in the difference between roller measured torque and derived torque calculated back from the engine rpm

Pure or roller torque is in the region of 1420Nm from 6000rpm which gives the engine plenty of pull towards the redline, but is hardly an accurate indication of actual torque. Now we bring up the derived calculation, which shows a closer and more accurate 880Nm. You can see there is a very big difference between roller torque - the way some here have been looking at their figures - and derived torque. I think actually looking at this we have a new Skyline torque winner as well

We should have some more figures very soon from a similar engine and turbocharger package we are engineering that will achieve the 1000Nm derived torque figure. As some have been heard to say, 600rwkw, its yesterdays 300rwkw

Nice looking graph there Martin, gotta love the 3.0L torque....

What turbos, and how much boost?

God Martin that car is an animal.

Thanks for sharing that information though, its really interesting hearing it from people who actually know rather than people who think they know.
