KB Owners: Looking for your WOT datalogs from the dragstrip.

I've been looking at my WOT datalogs from my track runs and something doesn't look right. I'd really appreciate it if any of you drag racers with the KB S/C could send me a few datalogs from your track runs? That would really help in deciding if I have a problem or not.

P-ratio
MAP Vacuum
RPM
Accelerator Pedal position

The car runs fine, but the P-ratio takes a slow arch up to full boost as soon as it hits 1, every single time.

Anybody running Kenne Bells on the LXF?

Here's a screen print of a log for 2010 5.7 with a 2.8 KB. I have the limiter set at 5600 for this customer until he gets some decent valve springs in the car. The PRatio initially jumps to 1.7@3000rpm in 1st gear then tapers to 1.9@5600rpm, in 2nd it hits 1.90@4300rpm and tapers to 1.95@5600rpm

Thank you. What boost are you running? That looks like a bit more than 8lbs.

That's the second time I've heard that one, but what does that mean? Are you saying the bypass valve is upside down or backwards?

Good, so no vacuum leaks of any kind, the bypass valve is on the wrong side of the boost/vacuum?

The vacuum line is hooked to the wrong port.

I guess that would make sense if I actually had more than one port to hook the bypass valve up to, but I don't. I'm sure you are familiar with the KB, so you know there is one port coming off the MAP sensor adapter and that's what the bypass is hooked to.

Anyone out there with an automatic car running 8lbs. of boost that can send me a Predator datalog?

**Hemi31** · 05-01-2012, 12:34 PM

You have no ports on the inlet side?

Thank you, your knowledge is very valuable.

Still looking for anyone out there with an automatic car running the KB with 8lbs. of boost that can send me a Predator datalog.

OMG, seriously? I sent a datalog to RobAGD, I guess I'm screwed now. Not to mention all the datalogs I sent to Johan. Sooooo, do you keep your datalogs in a safe in your wall?
