RE: OST-077: Nothing double natural about twincharging
As this is being twincharged (for those unknowing - twincharge is using both a supercharger and turbocharger in the same engine)...... Coming up with a cam for this beast was no easy task. After consulting with the engineers @ Cat camshafts, a "new" camshaft design was built.

258 overall, [email protected](.040") with 9.25mm of cam lift.

This cam should tick all the boxes, but to run this aggressive of a cam a shim over system just will not work, so this head will be running 1SZ shimless buckets.


To do this I have a set of 8 "sizing" buckets (8 of the thinnest) that I'll use to determine actual clearances, and then order the appropriate bucket to set the clearances.
