DRAGRCR ONESEAT DEMON WHAT ARE THE ODDS?

[DRAGRCR]

I see no reason you couldn't hook on that. I have run low 9s on the 315 and Jon has been in the 8s. The DBR i would think hooks better then the street r

I think it will with max prep. If we have the LOD event in Dallas and TJ Baily preps I will be golden. That guy knows his shit. But technically this is a 11.5 tire against the 10.5 DBR. Fortunately that size DBR runs wide at 10.9 on the tread.

@Diboblo has the instructions on how to disable tpms if you run drag wheels, that’s what I’d do. I don’t have tpms sensors in my drag setup, just billet specialties valve stems

AlfaOBD

BCM

Car Configuration Change

Disable all of these options:

Conversely, you can raise the TPMS threshold.

Just to make this perfectly clear. I happen to WANT TPMS. I do not need to know how to disable the TPMS system or warnings.

 

[Diboblo]

You’re typically always running 50 psi+ to meet the load rating on the front tire, and you can’t adjust the factory tpms system up that high so it’ll give you a warning, so imo tpms on the front are pointless anyway. @16GoManGoHC2 is a machinist/engineer, maybe he can weigh in on the saftey of the tap you did. It’ll probably be fine

Using Alfa, you can set your threshold between 0 and 126 psi. This will avoid any warning lights.

I thought it only worked +\- a certain number, good to know

So many mad faces lol

Why would you want TPMS on race wheels? I'm checking my pressures before every pass with a gauge.

I do too. By looking at the dash!

 

[Speedy!]

My gauge goes to the nearest 1/2 psi of pressure and usually doesn't match the dash close enough for me to trust it for racing purposes.

I can go around and carefully set my cold tire pressure to within 1/10ths of psi, but the TPMS will usually show a 1 or 2 psi difference in pressure.


That being said, I do like the TPMS as a fail safe, just make damn sure they are installed correctly (my same Colorado Mile story I've shared numerous times)

Is it accurate?

I know when I bracket raced, I had 4 gauges from the same brand etc. 2 read the same and 2 were a few psi off.

I'm not setting my race pressure with TPMS. Come on. Be realistic. In MANY cases they are surprisingly accurate. Even if they are 1 PSI High (or low). They are always 1 PSI High. We should all be able to figure out this math equasion.....

 

[DRAGRCR]

OK, guys I in fact discovered I was getting a flat REAR tire at Pomona using TPMS. I was driving around looking for Hellcat Dan and I noticed 15 and 17, and then 14 and 17, and then 13 and 17. You get the idea. Looked and had a big Screw in the tire. Dan's friend, Chris plugged it for me while I talked to some friends I had not seen in a while. My old neighbors from years ago....

If you guys don't want to use this TECH that could possibly save your life, then don't. But I am.

I think it's an issue of weighing the pro and cons of it. It certainly has it's place, however I'm the epitome of the double-edge sword that they are.


They saved me from running at ~175mph on flat tires, HOWEVER, they CAUSED the failure they saved me from, on THREE of FOUR tires....


Absolutely, use them as you see fit, but please at least consider the risk of using them.

A properly installed HELLCAT sensor should not cause any issues. My rears are OEM Hellcat/Redeye installed per the instructions. The fronts are Hellcat / Redeye being installed with a much higher grade fastener of the same size they they come with. I kind of doubt that little hole that is 1/25 the size of the valve stem hole is going to cause wheel failure.

I posted just to get any ideas of anything blatently unsafe that I did not consider or see.

Flatter the better, more traction and tire wrinkle

I don't remember what your issue was. But I am guessing they nuts came loose or they were not Hellcat sensors. I have found the nuts loose on sensors that I believed were properly installed several times. I actually use a torque wrench and they have still come loose.


These 22 up sensors have a much more robust rubber gasket that preloads a lot more and I am hoping they will stay tight. But I will be checking them after they are in use for a while just the same, like I always do now.

With my front setup there is no nut to check anymore. But if there is ANYTHING unusual I will have the tires shop investigate. I think what I am doing is likely better than banding them in. I have no interest in doing that.

Also in these Win Lite fronts with that small hole Valve Stem. You need to check them when removing them from the box. I have found them too loose straight from the factory. So loose that if you put the valve stem cap on thghtly they would just spin and eventually they will leak. Last 2 sets were tight. One before that and before that were loose. My friends were loose and he lost some pressure at our last event. Kind of scary to discover it by how the car is driving coming off the drag strip.

I just had 2 valves go loose on me. ALWAYS CHECK YOUR VSLVE STEMS AND PRESSURE.

 

[Unholy707]

Happened to me at track, was down 4psi in 1 tire. Valve came loose

 

[Unholy707]

I carry the tool with me and extra valves all the time and pressure gauge
