Ive heard somewhere that these cranks were done in Sweden

[Markus]

here in germany you could get cranks for
2,6
2,7
2,8
2,9

S14 engines.........
but it is a secret who builds them.......

Do you know anything about pricing Markus, for a crank and rods.
Are pistons needed?

[Markus]

Thanx Markus, Ill check this dutch shop also which parts they renewed.
Anyone any experience driving this kind of long strokers (>2.5):rolleyes:

[Markus]

my friend Sven ownes a 2.9l with 420hp

Green Beast

he said it is a complete different driving as driving with his other 360hp 2.5 DTM car...

runs like the hell he said

[Gsan]

the calculation the dutch add is incorrect B X S=93.4 X 91> 2494 cc[done]
95 X 91> 2580 cc

Great car Sven

are those the clutch and brake pedals? if so, how do you heel-toe?

or are they the brake and gas? if so, why are they both on the left side of the steering column?

I don't think you have to heel-toe with a sequential gearbox.

A competent machine shop can offset grind a 2.5L crank which would make the rod journals smaller meaning custom rods/pistons. I am sure you guys are building these big motors with custom long rods/pistons anyway to overcome extreme rod ratios.

Another good plus is a smaller rod journal means less friction and more power! Mechanical advantage rules.

Any word yet on crank and conrod pricing markus:idea:

[Evo2Trela]

In a sequential box you only need the cluch to start the car . so there is no need for heel-toe.
