I uprated the radiator and added an oil cooler. Ran it like that for 3 years, with %100 reliability.
About 2 years ago went the whole hog with the 65mm pulley, flex fuel, motec and a built motor.
About 346 hp at the wheels on E85.
Great fun.... but huge costs.
Been very reliable so far (after I solved the belt issues with the smaller pulley).

You really don't need to put vents in the bonnet... the car spends a lot of time in hot weather doing this with no dramas temperature wise:
222whp sounds a little underwhelming... Harrop claim 235kw crank with headers on 98 so 95hp loss seems a lot.

I would have expected 280 wheel on 98 and 320 on e85, then 350+ when you started upgrading the pulley and other components based on HARROPs info and in comparison to other kits
