The hole 2 exhaust thing was for the crowd the exits went allowed to be more than 300 or 400mm apart so you couldn't only hear 3 cylinders when they went past.theres been lots of cam grinds and blocks with bigger cam journals to get lift .i have a collection of different tunes out of them there's more than jasons (greenfoam) tune

Yes I have seen larger duration FH cams listed than in the papers.

Pretty sure I have that listed in the V6 cam tread in the mechanical section.

Definitely is. Kills the theory that a clutch fan uses no power.

Was enough to convince a mate to ditch his clutch fan on his 355.

I've been meaning to ditch my clutch fan for thermo's I have sitting there, will be doing it now

[psyolent]

yeah. long known theory.
that said, on i put the derale type fan (the 3rd one tested, after the plastic one), noticed a wee bit of power drop off as expected - but the trade off now is my hilux does not over heat, ever. i'm willing to sacrifice the power for no overheating.
that said my v8 is fucked.

glenn make sure they are good thermos and not cheap ass supercrap ones. the only other fan i would try is electric but last i checked it was about 700 bucks. SPAL.
