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

[infraredcalvin]

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?

Right now engine tune is my highest priority, yes as I glanced down I could see the AFRs creeping into single digits, so it’s stabilizing in the low 10s. The motor seems really slow to rev, like it’s running out of breath... possibly a timing issue. I found some old dyno sheets in some of the piles of stuff that came with the car, it was showing high 160s to the wheels. Im not sure if it’s the dyno for this motor as it seems really low for what I’m told is in this car, I think it should be well over 225 if not 250 at the wheels. But right now my butt is saying it might be true, could it eally be off close to 100 hp??? sounds like wishful thinking... we’ll see.

Regardless, torque is nice enough to hold tail to the ground, it spins slow, running out of steam around 5k - maybe cam choice? Lots of variables, that’s why I’ve got an appt set up with experts, want to be sure I’m maxing out what I have before changing expensive motor parts out.

As for handling, cars seems neutral, seems like I could hold much more though the corners with new tires, the old r888 are really unpredictable on this car, due to sizes I’m looking at yoko a052, hear they are the best for 200 tw at the moment...re71s don’t come big enough for 16 in rims. And my pocket can’t afford Hoosiers yet...

As for seat, yes, need to get it on the floor. I’m not a fan of any aluminum seats, watched a fellow racer get trapped cause the al seat clamshelled around his body, and he couldn’t get out without help prying the seat open. thankfully no fire, but it was a scary moment for sure. Lots of people run them, and this was prob a fluke, but made the decision to stay away since then.

I got my Recaros on the floor in the old car by taking out the cross support, it gave me almost 2 more inches clearance. I don’t want to do that in my 6, so I’ll have to come up with something else, but an inch would be a huge help.

On tires, check again on the Bridgestone RE71R's....I'm on 225 on 16's & really like them, very sticky....
