I was looking at the rules for the ECHC and I have a couple questions. I'm not planning to participate but just curious.

It says that that:
"Gauges that measure fluid pressures must be electric (NOT pressure-fed mechanical gauges)"
Why are pressure-fed gauges not allowed? Safety reasons?

It also says that rims can not be wider than 7" and all brake calipers must be a Honda OEM part. I thought the clubs usually restrict one or the other? What I mean is that they either restrict the rim size, or the calipers, but not both.

TIA!

 

Safety related to keep hot fluids out of the cockpit. Good rule in my mind!

On rims & brakes, two seperate rules aimed at keeping cost and speeds down.

Try putting an 8" wide rim on anything but a NSX or S2000 and see if you can keep everything inside the wheel wells.

What relation would a wheel width rule have with a brake caliper rule anyway?

 

I'm sure Scott and Karl may entertain the idea of mechanical guages that have an isolater. The isolator mounts in the engine compartment, the isolator then runs to the guage. The fluid in the line from the isolater to the guage contains H20 and Antifreeze.

 

Hot oil inside driver's area = A Bad Idea.

Not true. In IT racing you are restricted to OE calipers and a 7" wide rim. I believe NASA's Pro Sedan classes are the same or similar.

One minor clarification - it's not "any Honda caliper can be used." Brakes must remain as original equipment, unless it's an H1 Hybrid. H1 brakes are free, meaning you can do whatever.

 

I have a question. Why does everyone post questions about the rules for ECHC here instead of sending it straight to Karl and/or Giles. Do you just want a lot of answers from someone who isn't in charge, or are y'all trying to air Karl and Scott out in public. Sorry if this come out heavyhanded>

 

Why are you not at the track(Jefferson), tech dude... ?

 

Thanks for the answer on gauges. When I read "electric", I immediately thought of those gauges with digital display, which I haven't seen too often.

Reason I asked about the rim size and brake caliper is that I've seen some club in Europe that restricts wheel diameter to OEM, but width can be like 0.5" or 1.0" wider than OEM. With this rule, there would be no brake caliper restrictions - or vice versa.

Well only if you think it that way.

 

Actually, I never understood this rule either. I went with electrical guages just because they were easier to setup. Mechanical guages have a capillary line which has some other non-flammable fluid in it.

Besides, I'm sure most of the IT guys don't take out their mechanical guages when they run w/ us

Had a cheesy Oil Pressure guage in my 69 Camaro for a while... Hot oil all over the carpet sucked.

 

Then what about a Accupsump or fuel lines in the driver area?

 

Per the GCR (and NASA GCR - do you all it that?) Accusump and stuff has to be braided steel lines. Are the Autometer mechanical gauges steel lines or just rubber? I don't know - I used electrical b/c it was easier to install.

 

where does the ECHC stand on JDM bits? Can you use, for example, a Civic Type R pistons in a B18C or B16A powered Honda as long as they're stock bore? Or JDM pistons in a H1 hybrid?

 

While all of that stuff is in the rule book I'll make it quick for you.

Changing internals is not allowed in any class except H1. In H1 the head is free and the bottom end (pistons, rods, crank) can be changed as long as it is an OEM Honda part, which is where your JDM pistons fit in.

 

I like the rules posts. It gives everyone a better understanding of the rules, why the rules are the way they are, and answers to their rules questions in a public forum. Otherwise Karl and Scott would be answering 9 million emails a day about this stuff. Well, they probably already are but you get my point...

 

True, but it would be nice if folks would consistently bother to READ the rules before asking questions about them.

They are free
they are public
they are printable
they aren't read as often as you might think

 

a Civic Type R pistons in a B18C
he,he,he.........

 

something you want to share with us, tow-hook boy?

 

read the rules.....

BOTTOM END MAY BE SOURCED FROM ANY HONDA!

 

I did read the rules and they're not explicit about origin of parts. I didn't want to assume that JDM stuff was legal since the rulebooks up here in Canada do not allow European or JDM sourced parts under our 'update/backdate' or 'model variant' rule. Some rulebooks are specific about the use of non-USDM parts, some aren't. I simply asked for clarification. Thanks to those who answered my question.

 

Just to clarify... JDM internal bits are only legal in H1.
