Quote from: Ron Sutton on Apr 12, 2026, 01:34 PMThat seat is awesome. One thing Oval track racers do better is prepare to protect them selves WHEN they crash. Too many "Track Car" guys think it won't happen to them, because they're not planning to push the car 102%. Which is rubbish. A crash at 100mph is a a 100mph crash, regardless of intentions.

I caught myself saying something like this. Had to give myself a little pep talk about it basically as soon as I said it. Noone ever "plans" on crashing. It always happens fast and you have no control over it, hence, "lost control". Someone told me to buy the best safety equipment you can afford, and I've tried to make sure I do that.

A carbon HANS would be nice, but a fiberglass HANS will still save your life - you need one even if its not the best of the best. Make sure and install harnesses correctly. Fire suits are expensive anyway you buy them, so buy the best one you can. Fire extinguisher is better than no fire extinguisher, but you can't really use a handheld extinguisher effectively between the moment you realize you're on fire and the moment you're able to do something about it. I'll do a post on my fire system and harnesses. I think I did them as well as I could have, but its a good topic for discussion.

FuelSafe told me the Radium Engineering brand is hard to get sometimes. So they use the Fuel Lab brand more.



Deatschwerks also did their own version with a fabricated aluminum surge tank that serves as a top hat for the cell as well, so there's definitely options for keep it all contained in the cell. External surge tanks are also an option.

I helped a friend make an external version for his car since he was having starvation issues. It incorporated a box style in the cell to an external surge tank the fed the primary pump. The fuel return from the rail ran to the surge tank and then the surge tank had an overflow back to the cell into the box style internal surge tank. Extra component or two, but he really liked his hat and primary pump setup and didn't want to change it. We were able to make the external surge tank to a size and shape that worked best for the space available. Worked great! Solved the starvation issue. Didn't do anything more for using every drop of fuel in the cell, but doing time trials with short sessions on track, it wasn't an issue.

Something not common knowledge is all SFI suits come with a TPP rating.  The SFI numbers themselves can be a little vague. But the TPP number is clear.  Every TPP point is 1/2 second before the fire burns through the suit & gets you.  Have a 22 TPP suit? You have 11 seconds from the time the fire reaches you until you are burnt. 26 TPP = 13 seconds.  NASCAR requires a 39 TPP = 19.5 seconds. 

I'm telling you from experience, if your car catches on fire above 120mph, it is hard to get stopped in 11-13 seconds.  If you crash (or someone crashes you) & the race car catches fire ... 11-13 seconds happens long before the safety guys reach you.  Buy the best suit you can afford, with the highest TPP rating.

I'm a veteran racer & race car designer committed to staying on the leading edge of racing technology, for one reason, to win. Everything else is BS. I'm only semi-retired because I still love helping build bad ass race cars.

While engineering, geometry, trigonometry, physics & more affect everything in race cars, I do my best to make the complicated easier to understand. One of my racing friends said, "Ron is a race car designer that did not go to engineering school, so he speaks car guy."
