there are only three standard 1275 cranks apart from the en40 b cranks
there is very little difference between them all.
my fave is the mpi 6232 as its much prettier due to the balancing the factory did
saying that med like the 1505 crank as a exchanged!!!
all were heat treated as standard tufrided
despite what some may say the standard cranks are excellent if the journeys are good and there fitted correctly.
after years in high competition circuit racing motorsport i now use a standard crank. Ive had no issues at all , touch wood.
its a standard spi crank which was balanced 3 rd season now!!
my racer is 167 hp at the wheels supercharged.
a very quick car
a pal of mine has a n/a 8 port mini very quick car, he runs a arrow stroked crank, at £ 1800 each he has snapped three this season. his does 110 at the wheels.
he and his stupid engine builder ridiculed us for years using a standard crank.
make your own mind up.
