BillStrong · Post by **BillStrong** » Sat Jul 01, 2006 12:29 pm

1986 Toyota MR2 using a Cadillac DOHC V8.
Gutted chassis with 10-point cage
Single seat

What class will a special car like this run in. Where can I find a complete set of rules? Do you use the GCR?

Tires? will slicks be okay or do I have to use DOT tyres?

Thanks in advance

What kind of sound requirements are required for the exhaust and intake?

Hey Bill,

Great to see you here!

Sound requirements?!

You obviously haven't been to an event yet

We have some very loud cars (not naming names

)

As for your MR2, there are actually 3 "special classes" for the hillclimbs.
Here are some details:

SPECIAL CLASSES: Automobiles that are of a design and construction not covered in the TTR or Regional Classes of SCCA. All cars
competing in this category shall conform to the following specifications:
1. Meet the safety requirements as outlined in the GCR and TTR.
2. Have operating suspension on all wheels.
3. The chassis must be equally distributed along the centerline of the car.
4. The body style may be open or closed wheel.
5. Aerodynamic devices (wings) must conform to the description of aerodynamic devices included in the TTR SOLO I-II
Modified Class rules and/or to the GCR.
There will be three classes offered in this category:
CLASS ENGINE DISPLACEMENT
S-1 0 to 1650cc
S-2 1651 to 3500cc
S-3 3501cc to 500 cubic in
(A non-atmospheric multiplication factor of 1.5 will be used, turbocharged/supercharged, etc)

AFAIK, you can use any tire in Special, but there are stricter safety guidelines. Someone else can chime in on that, but at the least I know you need a cage instead of a bar. You obviously are planning for that anyway

Ya, I spoke with a company last week that will be building my cage into the chassis. After seeing Fabio's wreck I am going to have it over engineered.

So I will be in S3.
so what and who will I be chasing?

sound... ya, done some hill climbs in England. But this is the USA and on public roads, so I dont want the wieght of that muffler hanging off the back of the already heavy rear end.
