ello chaps!
Our entry level race crankshaft being reground to race tolerances then crossdrilled on both main bearings and big end bearing journals as Leyland Special Tuning
Then the crankshaft is wedged to our latest design to leave maximum counterbalance opposite to the big end diameter, then ni – tempered, checked for alignment, micro polished journals and finally balanced. ForceRacing (no idea really though what i want from this list) - Wedge crankshaft - £55 - Blade crankshaft - £55 - Backdrill crankshaft,eight positions - £60 - Crossdrill big end journals - £45 - Hand clean up of all remaining rough forged surfaces which leaves a much cleaner crank and reduces oil drag - £40 Swifty DC5.2 CrankShaft
The above isnt really an option but to shut lee up i thought i would add it :p I'm trying to marry up the like for like with regards to the cost of the med with what force offer and the med one seems to "offer" more on the face of it, although does cost more because it does give more from the list. or am i missing anyone off the list that i havent looked at? |

I know of plenty of folks (myself included) who run an absolutely bog-stock turbo crank. Mine is still on it's original grind too. No point grinding unless it really needs it.

I think for turbo use, most leave the crank and opt to lighten the flywheel assembly instead On 26th Jan, 2012 Tom Fenton said:

Mines a bog standard 6581 in its original grind that I bought for £5. 4000+ miles of abuse so far. In the 13's at last!.. Just |

I've had the majority of the force racing list done to my crank. Removed 1kg from it. I would recommend Carl above the other suppliers.

Don't see the point in machining a hardened crank as you are removing a substantial amount of the hardened material. wow 1kg really? hopefully carl will pop in hear and work his magic words on me :p Edited by t@z on 21st Jan, 2014. |

Think mine was nearly 2kg off! If something is worth doing, it's worth doing half of. |

maybe I might splash out one day - I looked before and the force work is very competitively priced.... |

I went wedged balanced and heat treated. The engine is much smoother I run a supercharger and I don't care the TB is on the wrong side.
