Diff Coolers

[MMiskoe]

...and if the Blowmeister air filter and intake comes with a turbo...? Jeez, guys.

I didn't say it was a slam dunk, but I do feel it falls in the category of the MAP sensor (before the rule change) or accumulator tanks for fuel cells. These are things that clearly reach past where they were originally thought to go and are based on the allowance that includes the word "any".

Really? Wow. Protest or a tech inspector doing a lot more than tech?

Yup. There is a note in the log book to have it corrected by next event. The sheetmetal that covers the fuel lines in the back of a Miata to be exact. I offered to come back w/ a paddock wide protest on tire pressures, alignment settings, spacing of class letters/numbers and washer bottles but was told not to. The whole affair didn't do much to endear me to tech.

We seem to have gotten by for a long time without these. Maybe I'm getting old and crotchety, but I don't see the need for the allowance.

You could say that about any change you make.

if we add open fluid coolers, I want the evap system and power steering to be allowed for removal to facilitate their instalation.

Secondededed. I installed an aftermarket power steering cooler on my car. The entire power steering system died after the next 1/2 lap on track. So if they're going let you to add coolers, I should be able to remove the whole system so I can simply remove the source of heat.

HA! Oil coolers and radiators are almost free now so that's moot.

That's big difference from a carpet hold-down clip, which is specifically allowed to be removed.. The rules state that there must be a metal shield/bulkhead between the driver compartment and the gas tank or any hose/tube that carries combustible liquid- i.e. oil or fuel lines. and/or those lines must be metal or metal braided.

This is a safety thing for all classes, not a you-can't-remove-that-in-IT thing.

In come classes (like STU), it's mentioned right there in the rules. it's also listed in the regular ruleset under 9.3.(28?) specifically regarding fuel cells, but the same rules apply to the factory tank too. can't remember exactly where it says it, but it's in there.

I thought that too when i read the post. But, thinking further, I bet those lines are metal. If they ARE rubber, then yea, that's a problem.

I'm assuming the cover he's referring to is the one that covers the fuel pump and the rubber lines that attach the pump/sending unit to the factory hard lines. there's a ~6" section of rubber line there on send and return lines.

If I saw a car roll through tech without that panel, I'd sure as heck put that in the logbook to fix.

I remember one of the first 6 hour races at summit point(which became the 12 hours) a bunch of 2nd gen RX7s were having diff overheating issues - most teams wound up replacing gear oil every couple of hours in the pits, some keeping their new oil on ice.

the next year I saw none of this. RX7s have only goten faster.

I don't know what the fix was, but the evidence was that it worked. I can't imagine a similar logic wouldn't apply in most cases. it might not be the optimal differential under the current paradigm, but a solution is out there, even if it's a compromise. what's that old saying, "in order to finish first, you must first finish?"

that said, I don't think coolers are outside of the philosophy, necessarily, only that I don't think their need is a foregone conclusion.
