It was speculated to be a chill, laid-back monitor day–the Grassroots Motorsports Track Day at the FIRM–the place we and our readers are welcomed by our official take a look at monitor for a full day of open pit lane and straightforward lapping. We had been joined by Randy Pobst, too!
And since he’d by no means pushed our endurance race automotive–an LFX V6-swapped Miata–I figured this was the proper place to lastly put him in it. I walked Randy over to the automotive, and he immediately landed within the driver’s seat like a bumblebee in a flower. “Glad you match,” I mentioned, “however let me take the automotive out for a number of laps first to get it warmed up and ensure every thing is okay. Then I’ll hop out and the automotive is yours.” We had no thought simply how shortly I’d be hopping out.
This was a automotive we’ve executed dozens of races in–one we’d already cleaned up, inspected and prepped after its final race, marking it “good to go” for its subsequent one. It was as “able to go” as considered one of our automobiles can get, save for the contemporary brake pads we usually set up within the paddock after a race weekend’s apply periods. For those who’re picturing some untested science experiment, this wasn’t it.
Which is why I used to be so stunned when it was immediately on fireplace. Braking into the primary nook after the FIRM’s longest straight, I noticed a puff of white smoke from the left entrance accompanied by a definite lack of deceleration.
“Crap,” I assumed, “I will need to have popped a brake line or one thing bizarre.” Then the automotive immediately spun 180 levels.
I now know why: as a result of oil was being pumped onto the monitor beneath my tires. And wow, that smoke changed into fireplace! A minor inconvenience had now changed into probably the most harmful a part of racing. I nearly couldn’t consider it–I’d by no means been on fireplace earlier than, and also you’d suppose it will at the least ship you an electronic mail or one thing to let it was in your schedule, proper? No warning. No warmup. Simply, “Hey, you’re on fireplace.”
I acquired the Miata below management, sliding to a cease proper in entrance of a nook station, then the following few seconds had been a blur–one I can largely bear in mind as a result of we had in-car video working the entire time. My bailout apply took over, and inside a number of seconds, I used to be out of the automotive and waving off the employees working towards me with extinguishers. The hearth was already out, and the Miata was nonetheless and quiet other than the hissing of its fireplace system and the large pool of oil creeping its method out from beneath.
Wanting via the trackside photographs, this was a small fireplace: flames filling the engine bay and bursting a foot or two out of the hood vents, with flaming oil falling to the oil puddle beneath the automotive. I estimate we misplaced 4 to six quarts within the incident–a lot to burn the automotive to the floor.
The trigger? A totally damaged (name-brand) becoming on the automotive’s distant oil filter adapter line sprayed oil straight onto the header. The repair took me a couple of minutes, and the fireplace system labored so shortly that I didn’t even have a lot as a melted wire to repair: just a few minor soot and a complete lot of oil to scrub up. I drove the automotive once more about an hour after pulling it off the trailer.
So, what did I study? First, fireplace programs are price each single penny. The Miata had an outsized Novec 1230 system from SPA Technique with three redundant activation strategies: digital, guide cable and computerized thermal bulb.
Talking of pennies: Don’t hesitate to tug that cable, both, as a result of my fireplace regarded method smaller from contained in the automotive. I had a short second of being low-cost and never desirous to waste the system on one thing small. Seems I’d have spent a whole bunch or hundreds of {dollars} extra to repair the inevitable injury if I’d let it burn.
Second, security gear doesn’t work should you don’t put on it. And dangerous issues can (and do) occur in non-competitive conditions.
[Track days: Is there such a thing as too safe?]
Like most monitor days, this one solely required a helmet. I gained’t get right into a race automotive with out full gear, and let me inform you: I felt great about that superstition as I watched flames dance out of the hood. Security gear is not any assure, however at the least you may really feel smug whereas your automotive is burning.
Third, apply your bailouts. I apply in each automotive and earlier than each occasion, which is why I used to be in a position to keep calm and get out of the Miata so shortly.
And lastly, there’s at all times room for enchancment–as a result of I skipped a important step that might have made this incident a lot worse. Electrically actuated programs like this one are powered by a 9V battery, and I take a look at it earlier than each session with the little “take a look at” button.
Do you know there’s a take a look at mode for the wiring, too? I examined the connection after I put in the system, however hadn’t since, which is why I had no thought there was a damaged wire within the circuit. That’s proper: The Miata’s fireplace button did nothing after I pressed it on monitor. Hooray for the cable backup launch–and the automated thermal bulb that will have theoretically popped the bottle if the passenger compartment had gotten too heat.
This might have been a column concerning the lack of my race automotive–or worse–however finally, it was about an previous adage that I sadly examined in actual life: Fireplace burns simply as scorching on a take a look at day.
Feedback
I’ve touched on this earlier than however my one and solely automotive fireplace was on a take a look at day. Very similar to your Miata the motor let unfastened and brought about an oil fireplace………….going into the quickest nook on the monitor (round 130mph).
I put on all of the gear on a regular basis as a result of issues occur.
As I used to be sitting right here attempting to provide you with one thing witty to say about Randy getting within the automotive after you “warmed it up” for him my mind went down a extra severe path.
I began enthusiastic about what number of completely different scholar and buyer race automobiles I’ve climbed in with out taking the time to know tips on how to activate the fireplace system or shutoff the grasp kill change. I ought to try this.
Then I began enthusiastic about how a lot of the bailout apply I do alone automobiles will translate to different automobiles. I am unable to see me training in one other automotive however I actually ought to at the least take into consideration potential challenges for getting out whereas I am strapping in.
My final thought was actually extra of a query for Tom. While you mentioned you drove the automotive once more that day did you imply that it was transferring below it is personal energy or did you imply you had it out on the monitor? If it was the later I query the knowledge of doing that with a discharged fireplace suppression system proper after proving the worth of a practical system. After all I am questioning that from a distance. I may need executed the identical actual factor.
Tom’s at HPX however, after the fireplace, the automotive didn’t return on monitor–simply into the trailer and residential to the store.

Sensible choice and, a better one than I may need made.
I had a engine fireplace simply in my driveway, on a automotive that has been collectively, extremely maintained and pushed for a decade. In my useless makes an attempt of not waking the neighbors I did not fallow my common startup processes. That grew to become expensive as soon as it backfired out the consumption and lit the filter parts on fireplace. Fortunately i had a fireplace extinguisher available, this might have be far worse. Img is me blowing the fireplace extinguisher mud out of the engine bay to guage the injury. Tl:dr E36 M3 occurs typically on the worst of instances, do every thing you may to be ready for it.
I bear in mind the primary time I needed to put on “full gear” after I drove my buddy’s WRL NB.
With my very own NA monitor rat, it had no prime, 4-pt roll bar, mounted again seats and 5-pt harnesses. So it was simple to get out and in of and go searching. It was simply closed toe footwear, lengthy pants, lengthy sleeves at Hallett.
His NB I felt fairly claustrophic in it. Full cage, nets, HANS machine, could not actually get my hand out the window for a degree by (it was a WRL monitor weekend, not a race weekend). It was tough to get snug like that in only one weekend.
True, a caged Miata can really feel tight. First time I drove my good friend’s SSC Miata, I used to be like, um, that is completely different….
I have not been carrying a fireplace go well with in my monitor day Miata because it has no prime and a manufacturing unit gas system, so it at the least feels secure sufficient that I can bail shortly if issues acquired toasty. For the inventory automotive although, I plan to solely drive that in full gear head to toe – it is a lot tighter and tougher to get out of, and it typically feels prefer it requires a better stage of security precautions to be taken.
