can anyone post a graph of the cooling line pressure on a run

Are you having an engine thrust bearing issue?

no just wandering what that pressure would look like,mine doesnt look right to me,but i dont know

Rusty, Steve jr is gone for the weekend, I will have him pull a couple of graphs and either post them here or send them to you in the next couple of days. Not sure where you have your sensor mounted but mine looked really weird when I had the sensor mounted directly in the cooler line. Randy at RPM said it was due to senser seeing too much heat. Once I mounted it remote it looked much better. We also tried a cooler line dump valve for awhile but ended up taking it off

Don’t do anything to that car you might screw something up. If I were winning as much as you I would just say a prayer over it every day!

Agree!

lol the car is deffinately much better than the driver.probally wont change much just trying to learn.thanks steve that would be helpfull and no hurry

Rusty this is from a 6.12@230 pass from Pomona earlier this year. Cooler pressure is blue scale is on the far left. Curser is at the 6.10 mark

thanks steve

Lots of fun info in that graph ! Do you think it lost the wheel speed sensor signal at around 4-1/2 seconds?

I'm assuming all hell breaks loose if you leave higher than 3200?

Crazy jump in trans pressure after the gear change...interesting

That is a loose convertor !!

Yes signal from driveshaft sensor skipped a beat. Actually that was my tight stator in the converter. Air was really good in Pomona, 30lbs boost at only 16:1. Fuel Flow meter showing 10.05 GPM at the stripe at 187 psi

Even leaving at "only" 3200 it still turned the tire a little.
Wild how the belt-driven pump starts putting out instantly

Do you run that convertor to keep the MPH down or is it just happeist with that one?

230 MPH on that pass. Has gone 235.70 so no I was not trying to keep the MPH down, just the opposite.
Engine is for sale if you want to go fast

Meant no offense...
I have a few friends running TD and we sometimes get on the subject of MPH.....Since NHRA put the ET stops on we figured the TD crowd might start pumping up the MPH for show...we figure that'll just make NHRA cap that also.

Here's one from our dragster from a couple weeks ago

scott is that one measured at the servo?

that looks like pump pressure not cooler pressure?

Yeah sorry that is at the servo

looks like a flare on the gear change if you ask me.
