Caterham's

[Neil Gault]

Not driven the Caterham's for a while so how about an event with these some night guys?

Guess you have seen Gary's latest addition by now?

Any tips and advice on setup (and how to keep the engine cool at Ruen?)

yes i had a big grin when i saw what was coming :smirk: just love these things even though i will probably spin every couple of laps they are just great fun to try and master.
Just ignore the oil temperature warning you get with race07 pd or RTT as they are set for oil at 100 max but the cats are a bit different in that you can take the oil up to 125 before it starts to destroy the engine, so just thrash the guts out of them.

from the engine file
LifetimeEngineRPM=(8700.0,100)
LifetimeOilTemp=(125.10,5)
LifetimeAvg=20000
LifetimeVar=5000
