some in car vid from an open track day Friday, been awhile, thought I would drop by... Options

Took some video of an open track day this last Friday. There are three of my most consistent, fastest laps to date, all in the 1:55s. I ran one 1:55 the last time I went out with consistent 1:57s after I put some old radials I had laying around on the car from a couple years back, so I got the most out of them the last track day. This time they held on for about 4 laps in the morning, and then just got greasier and greasier as the track and the day warmed up.

So I have three clean laps back to back at the beginning, a slightly slower overall time lap as the fourth but there was some neat traffic so I left it in and it was my fastest shot down the bobsled to hell and sliding back up the hill, then some footage of traffic to see some cars, general bloopers and random chaos.

And then I realized upon editing that I left the camera on when I finished, so I got a bunch of footage of various folks coming up and asking questions, talking about the car when they thought I couldn't hear which is always funny, but I threw in one snippet of a corner worker that worked down in that area I would go sliding through and the open wheeler spins.

The springs are getting stiff enough that I know I have to get the right camber set on the car, some new radials, then monkey with tire pressures. I suspect that I am in the "1/2 psi makes a big difference" spring rate range.

Took the car out after not tracking it in almost a year (!!) so I was a bit rusty and running 2 minute laps in the first session. And I dropped the air chuck right on the windshield while airing up the slicks and cracked the crap out of it on the passenger side. My cousin was out from Iowa so I took him out for two sessions while I knocked the rust off my hands.

Finally in the fourth session as the temperature went well into the upper 80s and both me and the car were running hot (300deg oil temps and I could barely swallow after 20 minutes on track!) I ran a 1:54.97 and backed it up with a 1:55.12 IIRC, so two of my fastest laps yet! I overfilled my trans (the first time I have ever done that one) so I was puking trans fluid out the breather and probably oiling my own tires as every lap I went a little slower and the rear got looser and looser (IMG:style_emoticons/default/icon8.gif)

I put Goodyears on which I have never used before and eesh, they will required a LOT more camber than the Hoosiers. The wear pattern was way off so I believe with about a degree more neg camber all around I can maybe dip into the 53s. That is Porsche Cup Car territory (IMG:style_emoticons/default/sunglasses.gif)

I will post some vid on Youtube in the next week or so after I get a chance to edit all of it down. Fast group was actually all fast people as well as fast cars for once which was awesome, so I had pretty much a wide open track and found that I could pass the others and not worry they would freak out and run into me. And giving my cousin some rides with lap times that would break the Super Production record set by a fellow V8 914er of 1:57.4 was the best part.

One thing I was discussing last year in this thread was the rear brake bias - I decided to put stock pads back in the rear because I just had too much rear grip from the race pads and I really looked at my bias and it was fully maxed to the front and no safe way to go further. WELL, that is a little too far the other way - I had to move the bias toward the rear and then I really hammered deep after that long straight and a bunch of SMOKE flew into the cabin and it was the rear brakes and the car was squirrely! So I really need to find a race pad that is in-between the two. So again, I found I couldn't really push the braking. If I get the camber right and the brakes right I think :53s are no problem at all.

Gonna make it tough tearing that car apart to build a 66 Nova instead next year. I am going to try to track it a few more times this Fall to wring out all I can before moving on...
