Good Ol' Uncle Pete has a VN with the V6 bored out to 4.2L and quite often embarrasses those who think they know.I ran a modified VN V6 for years, tyres used to last me a couple of months, I bounced that motor off the rev limiter nearly every day .
I didn't even bother putting mags on it because replacing tyres bigger than 14s would have made me go broke.
If the cooling system was designed well and maintained they seem to last as long as each other. Pretty sure most cavitation is caused by a restriction in the inlet of the water pump, possibly a particularly clogged radiator or inlet hose sucking in, and then the acidic coolant that people never change finishes them off.
You most likely need to slow the pumps down with a bigger pulley, they're not designed to be held at almost full throttle most of the time. It's the same with belt-driven pumps on most old cars, the water pumps end up exploding if you hold the revs up too long. I'd imagine that most people would go to electric pumps these days.
(I'm happy to get reamed by the euros, and I don't drive that fast anyway)
What! I can assure you that an M is covered for track use, also never heard of this exploding impeller business.
Have you blown up your BMW at the track and had it covered? I've seen people who have blown theirs up and it's not covered.
It's only on the older models, most of the new ones have an electric pump.
He was a punk?
It's not a genuine Cooper S but has been tweaked to mostly replicate one. 1330cc engine with 45mm Weber DCOE twin-throat carb, 12" wheels with big (for a Mini) 8.4" vented disc brakes on the front.
AFAIK mine is still the cheapest Evora to ever trade in Straya ($76k). I have super fond memories of that car, but do not miss it. You needed to drive it at a ludicrous speed for it to be exciting, and shit just kept failing over & over again (as Tubbsy alluded):
There would be other factors if not covered. After 15 years, never seen an issue with track day work on M's since the E90/92.
Square front? We had a 1275LS for many years.Anyone want to buy a Proper Mini? Economic pressure dictates that I need to sell my long-term project 1970 "Pseudo S".
Next step is a bmw L series head...
When you say cool on the radiator end of the hoses, are you meaning the main radiator (behind the grille/bumper) - or the heater core?
The main radiator, heater hoses are warm to hot but the heater only blows out luke-warm air, my thinking is the water is not flowing through the system and the coolant is only hot on the engine side of everything.
