Damn the torpedoes!
I'm running in ASP! I've been searching through some old posts on here about autox and came across that one talking about aftermarket radiators. I refuse to run in another class simply because I have an aftermarket radiator. Somebody's going to have to lodge a complaint if they want me to run in another class! Do you guys think I should run in ASP or move up to a higher class? This will be at the regional level, not divisional.

Generally, there aren't many protests in a regional event for that level of infraction. I would imagine that you are looking at putting in a thicker, heavier radiator in for better cooling during events that are not autocross? I believe the rule is made to prevent you from running a tiny Civic radiator as a weight savings. Still, a rule is a rule; you simply need to know your competition, and whether they are protest-happy.

I ran a celica that had a full veilside kit with flares in a stock category. Nobody protested, so I'm sure it'll be fine. I just think it's stupid that such a rule exists.

At a national competition level, such rules start making sense. When people are throwing cubic $$ at a car just to get the last little fractional second out of it, it's amazing how "creative" they can get with replacement rules.

I did wonder if anyone ever replaced a radiator (in SM) with just a solid piece of metal (like a pipe) and manually cooled the motor between runs.
That would save you ALLOT of weight if you could get away with calling a pipe a radiator. Of course, I'd never do it for a FI car.
Back on subject...
I refuse to run the stock radiator in ASP. I want to be somewhat competitive at Divs and Nationally, so I'm reading the rules repeatedly.

I am not familiar with the FD's. However, if engine temps are a concern, you could also look at an oil cooler. I believe you are allowed to install an aftermarket oil cooler in SP.

A large radiator really is a performance enhancement for the RX7; colder engines make more power, when wins often come down to thousandths, every bit counts.

At the speeds Solo runs at, I seriously doubt that having a larger radiator would help more than it would hinder. I thought there was a few people who were petitioning to get the rules changed?

The same seems to apply to SM2, but I doubt many SM2 cars are running a stock radiator. My car is in SM2 with a Koyo radiator.
Any SM2 drivers have experience with aftermarket radiators and interpretation of SCCA Solo rules?

One of the most weenie protests I have seen was a guy in a 3rd gen protested a Corvette in SM2 for the radio cover plate missing. Funny thing is the Corvette driver jumped in my ASP RX7, bettered his time and came out about 4 seconds ahead of the guy who protested him.

I have allot of time to make up if I want a ASP/SM2 trophy at nationals, but I'm not so delusional to think I have a chance vs the top dogs.
I asked about the radiator removal in SM, because the drivetrain is unlimited.
Btw, how are you running a BSP pax at your region ?

I personally feel that they should rewrite the rule to something like the rule for fuel cells. Replacement has to have a capacity equal to or greater than the stock size and be located in the stock location. I have written a letter to the SEB requesting this change for Street Prepared.

The extra 7lbs of water means nothing as they will burn that much gas in one run. Having the engine 10c cooler and the air temp 30c cooler= more power.
Conversely, I would suggest that you also lose power in subsequent runs with a smaller, less-efficient radiator; especially so with a co-driver.

I have run my FD in SS, SM2, and ASP and trackdays for years with the stock radiator without a single cooling issue. I run with the heater on high, radiator fans on high, and pop the hood between runs. I took out my A/C condensor and filled in any spaces in the air box in front of the radiator. I also have a larger SMIC which I feel is better for Auto X and is a legal mod for ASP.

If you can show me something in the rules about radiators in ASP/SM/SM2, I would like to know where it is, as I either can't find it (searching in the PDF version of the rules) or I am not interpreting it correctly.

They consider the cooling system to be a related component of the drive train, thus it is unrestricted in SM/SM2.

All part of interpreting the rules I guess.
