Thanks Mark. What did you see for oir pressure around turn two. The temps. probably never got very high.

twice the HP as the lemons racer with an in radiator oil cooler and water temps right at 1/2..... yes I'm jealous!!!

Its okay I think I finally solved the temp issues in the lemons racer!

Temps were below the middle of the range. At one point in the race, the fan actually turned off.
oil temp was 230 to 240F. remember, i only use one cooling fan of the 2 available. I used the 2nd during the hot days to keep things cool. even in the worst conditions, temps dont get much over the middle of the scale. stock radiator, stock radiator oil cooler.

oil pressure just below the 5 bar mark, even in the heat of the battle. never below 4.5, and that was the lowest it got anywhere on the track.

Congrats on putting that racecar together. Sounds quite healthy. Good luck on your upcoming season.

I've been waiting up for that!

That engine sounds terrific, Mark. What was the little wave you did after coming off the rumble strip on turn eight, second lap. Was that to remind yourself of something when you watched the tape later?

Good work Mark .. I've been waiting for that too! Motor sounds strong. Get the aero stuff back on, better rubber, less weight, a bit more detail sorting. Maybe looking good to beat your previous best times seeing you're not really all that far from them, all things considered? How does the stiffness of the chassis/cage compare?

mark kibort

A couple of people came by, just to say how good the motor sounded. Nothing has changed, so I wonder what could be different. power felt the same or maybe a tad better, but who knows. . the little wave was to rememeber to take that segment at turn 8 and compare it to the previous chassis on a similar lap. It was a little near the edge, as it was slidding out to the exit birm.

I have to imagine that the car will be a little faster. It actually handles better than the previous car and I dont know exactly why. could be the rear alignemen settings, as I took the advice of the alignment masters from Kip and Darrell's team, and added a little toe-out. I think that might have been part of the push problem i had before. The chassis is perfect and has no issues, where the Holbert chassis did have a lot of races on it. I think the chassis with the 130lbs of cross weight, fixed with the cornerbalance change, along with the wing, splitter and drop of 60llbs, with better tires, it should be faster.

Did you see the little spin out of the cars in back, after the start at turn 1?
Also, no oil burning, maybe used 1/3 of a quart, and no smoke out the rear anywhere on the track.
all shifts near 6000-6600rpm
No spacer, no baffle, no overflows, etc. The stock stuff works great with some minor tweeks.

Mark Awesome Job. That looks like to much fun. I like the sleeper look. Nothing like getting under the competitions skin with and old Porsche that isn't all pretty then sowing them what time it is!

The "new" junkyard motor in the lemons racer doesn't burn much oil....& I think we fixed the leak problem....since it doesn't drop anything on the ground now (besides the power steering drip) ....

For sure the cross drilled crank helps with oiling...but it will not stop the oil starvation problem...so the gauge should still register drops..... It will be interesting to see how the Widow holds oil pressure compared to lemons or your racer

I wonder if the length of race effects the oil pressure loss problem...it makes sense that a sprint race has less time to loose-consume oil and plenty of time to check-replace it, in between races.....so that has to be a consideration....the 1st engine in lemons was 3 quarts down after 2 hours.....typical was 1 qt per hour on track...& of course it didn't last long either..

No matter how to explain or not explain it.....MK's stroker continues to be trouble free on track......

Notice how the wheel and tire is much more stable than the holbert car was? (in the side cam video) I wonder what that is due to? the car felt real solid. Now, its ready to go. all the bolt on goes on this weekend and splitter design starts to get put into cardboard. hood to be vented as well. I wonder what shape I should use for that. the old trapizoid didnt look that bad with a screen behind it.
