My KPM800 track test (KPM 800HP Track Pack Fuel Pump)

[Deadly0ne]

It's a new club that features Mustangs that go to Hallett. They are going to do an event once per year. They did a car show and a track day. Not a big turnout, but it was hot AF and I think I did more marketing for it than the actual organizer.

You could always come out this weekend! Another hot day (104 Saturday) but always fun. I'm hoping to make some Corvette owners 2nd guess their decisions when they point me by in my GTI.

Send me some info on this club - Unfortunately I can't this weekend. Got to plan around the Mrs. and the little one.

Watching your video, you're carrying a lot of speed into the corners - impressive!

I have not experienced the fuel cut issue on my ‘23. Good to know info. I gotta get some track tires!
Was the 1:24 on E85?

Yes, I use E85, well......more like E77 based on my E sensor, on track. More power and less heat generation.

Make the short drive to Oklahoma sometime and get on track with me!

I can not say enough good things about the Potenza RE71RS tires. Granted, they are the only 200TW tire I have used, but they just get better and better with use. I had no issues with them getting greasy in the 100+F temps. I am at -3.5F and -2R camber with minimal to no toe and the wear is even. They have cool little triangles on the sidewall to let you know if you are rolling on the edge of the tire too much. I actually look at tirerack and discounttire almost daily to see when they will put the last stock of the RS on sale. Going to stock up. I use them on both of my track cars.

Awesome thanks for the tire info! Oct 3-4 I hope to be at Hedge Hollow in Missouri for Hooked on Driving and maybe time trials

Good luck and I hope you get to post some videos of the day!

Yeah those little triangles are just to show where thr wear bars are at in the meat of the tread. Pretty sure every performance tire has them… maybe every tire? They have nothing to do with inflation pressures, aside from residing on the sidewall, in the general ballpark of where scrub marks may end. You arent the first person to think that, but its bad info.

Yes the RS is a great tire and looks like the RZ which replaces it is great too.

You're a brave man for even taking your car out there in this heat, let alone being able to set blazing lap times in it. My off-season in Texas is late May through mid October, heh.

Yes to the problems w/the OEM pump. Ford issued a recall because they suck at making fuel pumps for the 18-23 5.0's. I was getting massive fuel cut tracking out of fast left turns and when over 6k rpm. I tried the DW400 pump and had the same issue. Tried the DW400 module. Same issue.

The KPM800 let me go full send for five 20 minute sessions in 100+F temps. I am a fan.

My car does not, nor will it ever have forced induction. Worst thing you can do to a tracked 5.0. I do use E85, but was getting fuel cut even w/91 octane.

Side note, there were a few 09-14 GT500's at the track. All of the drivers faced CHT and heat soak issues within 2 laps.

Guess 20-22 GT500s don't actually exist then. There's nothing wrong with adding boost to a track S550. My choice wouldn't be positive displacement like the shelby's use, but either a centri on a budget, or turbo if price wasn't a consideration. The coyote will run all day under moderate boost if you aren't an idiot and actually address cooling properly like you would for any vehicle you are adding more power to, NA or otherwise.

Do you have personal experience tracking a boosted Mustang? I do and it doesn't go well. Several other members have had the same experience. The issue w/a Centri is 1. Massive heat generation. 2. a big ass intercooler placed directly in front of the cooling stack which causes a reduction in air flow through the all important radiator.

These 2 factors cause a rapid increase in CHT and oil temps, which does not bode well for track use. Ask me how I know.

Sure....the GT500 can haul ass for a few laps, but they do overheat on track. I have seen it multiple times.
