Tracking the 914 - Need some street love too..., Turning this into a regular thing... Options

1st track day in the bag with the new 914, no decent pics yet (there was a photog in attendants, but haven’t seen his pics yet). Car rand great and although running with much newer machinery she was holding her own once her driver brushed off the cobwebs... (IMG:style_emoticons/default/driving.gif)

Since this was essentially her first shakedown I found a number of little things I need to address, one in particular I’m questioning:

After a few laps I noticed - mainly on a flat sweeper turn, when entering hard on brakes and trailing off while turning in I’d get a soft groan from my outside wheel (drivers in this case). I’m thinking wheel bearing? I’ve never had one go bad on the front spindle before, so I’ve never heard or felt the slight vibration before. Never really occurred on any other turns.... thoughts?

Yup, the old FAT was next to my dads work growing up, I used to wander in there and drool over all the shiny parts as a kid. Promised myself a FAT build someday when I bought my first 914 as a poor college student. Finally almost 30 years later here we are.

We’re talking about 2 different target builds depending on condition of my 78mm crank, 195 hp if mine is refurbish-able, or 205 using their 82mm crank. But we’re talking about a durable performance engine vs max hp.

As far as my blown parts , old engine had(s) a scat forged crank, it looks surprisingly good, some chew marks on the counterweight, needs to be checked out. Cam looks ok too. The carillo rod (and je piston) took the biggest bashing, bent and snapped the end cap bolts. Adjacent rod has a ding in it, and it’s piston has a ding on its face, they’re most likely junk.

What may have saved the crank was the thinner walls of the cylinder, looks like it pushed right through the top of it, taking a portion of the case with it.

All will get throughly examined, measured, and tested before reusing anything. Overall wear was surprisingly minimal inside engine, crank and cam bearings could use freshening, but could still see crosshatching on surviving cylinders, pretty good for a 20 year old build with mostly track miles... always on Brad Penn changed yearly.
