Hi all,
So I'm thinking of the next TR-6 engine I'll be building for Walt
Holowell and I'm wondering what the crankshaft options are,
besides Moldex (c'mon Walt, buy me a Moldex).
His current combo runs a stock crank and rods (polished,shotpeened,arp
bolts) and has put down 135rwhp which should him at
about 170-180 at the crank(I figure his od tranny is responsible for a
few extra percent loss even though it's not engaged on the
chassis dyno).
I'm no Triumph expert, so at what point does the stock crank become a big
liability, I expect this engine to rev to 7000-7200 rpm
and hopefully put out about 210-220 at the crank,is this too optimistic?
Since Walt attends southwest regional events and does not chase national
points I don't want a short fuse, what will be the expected maintenance
intervals on such an engine(rings,bearings valve guides)?
Probable combo: Pauter rods
PRI cam and lifters
12:1 JE or CP pistons
Big valves and lots of porting
Goodparts roller rockers and tubular pushrods
well baffled sump as per current engine(3 trap
doors courtesy of Stanley door hinges)
40mm DCOE's or possibly PRI's Keihin setup
Did I miss anything Walt?
All input would be very welcome.
