Interesting to see crankcase pressure logged. Never seen that - what do you use it for?
Oil pressure looks good.

the last turn @ Lightning and the 3-4-5 complex seemed to have the potential for causing starvation.

On a totally unrelated starvation note - I ran with the low fuel light on for a lap before I got a hiccup.

OT - Momentum - what other events do you run?

Momentum

I have a swirl pot for the fuel so I can run down to 1 gallon in the swirl pot and still finish a lap I actually finished a lap with .3 gallons left but the low fuel pressure warning went off a few times.

I'm probably going to the Sebring RTA event and other than that just random local stuff (VIR, CMP) I'll make sure I post up any plans when they become definite.

I use a regular 2 bar GM map sensor bolted to the valve cover to log crankcase pressure.

Momentum

Oh and I use it for absolutely nothing. Just making sure it wasn't too high and so I know when my motor is about to blow up. My favorite thing to work on is the engine management and data acquisition stuff and I don't think you can possibly have enough sensors so I just keep adding them as I can afford it. I find it a lot easier to justify since if I ever move to a different car or total this one I can take all that stuff with me to the next project. You can never have enough data my best story yet about all these sensors that seem meaningless is finding a failing wastegate before it caused damage. I have two EMAP sensors one in each side of the twin scroll manifold which may seem like a total waste since they always read the same. Last year at Englishtown I thought one of my sensors failed, it was reading much lower than it should have and boost and everything else was still fine. The next session the car was running a bit rich and felt like it might be a bit down on power. Since I had nothing else to go on I assumed that sensor was reading right and decided to take apart the wastegate on that bank to reveal the nut holding the wastegate valve to the diaphragm almost completely backed off. You never know when that crankcase pressure sensor is going to start reading high only to reveal that one of those one way valves has gone bad. All that daq is the reason I can beat my stock motor to death at 600whp all day long on the roadcourse and not have any failures.

Totally impressive that it lives to fight another day. Open deck, stock everything? and all that boost...

Its only 300hp per liter...!!

Ever think of running in NASA TTs?

I'd love to be involved in that or some wheel to wheel racing. The bottom line is just this one event pretty much broke the bank for half the season. I can't really afford to compete for points anywhere and the RTA events are where most of the shops show up to compete. I'll do maybe 3 major events a year and that's all my bank account can handle for now, who knows maybe this year that will include a nasa event. I know I'm going to try and have the car back and ready for the Sebring RTA event in a few months and probably one more big race after that if I can.
