SCCA Solo ASP Class - Radiator Allowance Change

RX7Club Members,

Could everyone please email [email protected] and express your support for the proposed allowance of radiator modification is *SP (Street Prepared) class! They are looking for input on the proposed change. Lets show some support. If this passes many of our mildly modified (read: reliability modified) FD RX7 will go from SM2 to ASP and become more competitive!!!

Thanks!
Jake

And while your at it why not request a reclassification of the FD RX7 from ASP to BSP and from SS to AS.

We might as well ask for a reclassfication of TII's to CSP and DS and NA FC's to DSP and FS!

I've actually considered writing a letter about reclassing the N/A FC fo DSP. The 240SX is in DSP, and aside from the fact that all 240s came with a back seat the two are fairly well matched in terms of weight, power, tire/wheel, etc. Don't even get me started on the BMWs that are in DSP.

I'd be willing to put together a proposal if others would like to contribute...

I wrote a letter in support of this too.

Now to a detail: the proposed rule will require both dry weight and capacity of the radiator must not decrease, and it must use the stock brackets. It's the first criteria I'm not sure about. Anyone know if a smaller aftermarket rad like the fluidyne actually has a larger dry weight than a stock rad?

In my letter of support (written in March of this year) I recommended that they change from requiring equal or greater dry weight to equal or greater wet weight. That seems to make more sense, and it's not really any harder to enforce.

I'd agree that the first bit would probably be hard to follow with an aluminum rad, but a lighter aluminum rad with increased capacity should make just about any off the shelf rad heavier than stock.

Looks like persistance pays off. Good job guys. October Fastrack:
http://www.scca.com/documents/Fastra...strack-oct.pdf Look on page 6.

Now we just need the car to be classed BSP instead of ASP ( not that I am really looking foward to racing the EVOs- I have raced against the Showcase Mitsus locally when they were BSP... WOW.- )


On a side note I just read through your build up thread S1mpsons. Good work and a good read.

If you look down the new rules a bit you see some cars that just got bumped down from ASP to BSP:
M Coupe
M Roadster
Z3 (6 cyl) seperate line
E46 M3
Solstice GXP SkyRedline

The FD is still a competent car but there is only so much you can do with stock turbos and stock gears. If anyone has raced against a prepped M Coupe you know that the 7 is similar in times to that.

I'll be home in Mid October and I have a fluidyne that I can weigh. I may or may not have a stock radiator laying around to weigh. I have a Koyo N Flo, but it's in my track FD and I don't plan on taking it out unless something happens. Who knows, if no one steps up I might flush my coolant system or something and pull it out real quick and weigh it in the process.

The skinny core and plastic tanks of the stock rad should ensure it it lighter than any aftermarket rad. Don't know about the fluidyne or others, but the Koyo is definetely heavier than stock.

Should have weighed mine before junking it.

KOYO and fluidyne should be able to provide these measures if myself or someone else has the time to place an inquiry. Then we just need a measure of an OE unit.

The core material for the stock rad is denser though.

stock radiator is 7 lbs. according to my handy-dandy bathroom scale (might be a few ounces more since my scale only reads weight in whole numbers). I'd have thought that it weighted more
