Which class...from a newbie

Postby SevenhundredS » Tue May 07, 2013 12:06 pm

This is my first time through the classification charts/system and I'm not entirely sure I'm getting it right. Some charts stop at #4 and others go up to #6 (but this one goes up to 11...comic reference, never mind.)

I'm entering a production model 1962 BMW 700 S.
It is a 697 cc flat twin rear engine, four speed...all stock for the '62 BMW except it has an electronic fuel pump with a fuel cell replacing the oringinaltank and mechanical pump.
It has 13 inch aluminum wheels instead of the regular 12"
The back seat has been removed and full roll cage added.
No bumpers.
5 point harness for both seats.

So I think I have either a "Street Prepared" that will be assessed weight shaving penalties or a "Prepared" since it isn't road registerable, I think?

I'm entered in the Ascutney Hill Climb. With only 40 horse I doubt it will break out in time but I'm hoping to have a fun safe introduction to the club and sport. Will the tech inspection simply look it over and put in the appropriate class?

I posted a picture to the FB page and have more.

There is an excel sheet on this site you can download and it will do the math for you. Tech will make sure you are obeying the safety rules, but likely wont class you. They may offer suggestions. We are pretty informal on class selection.
Tires are likely to be the biggest factor.
Non DOT tires wll put you in prepared. DOT approved tires will likely make your car SP legal.

Don't worry about the class too much. Just take your best guess as to what Street Prepared class you think is correct. If someone figures out you are not in the correct class we can change it in the timing software anytime before we create the final set of results on Sunday.

If your're running in P, you'll need a firesuit. Don't worry what class you're in (with only 700cc, it would be 6*) I would concentrate on getting everything you need to get thru tech-an ABC fire extiguisher with a metal bracket (even if you have a fire system) positve terminal covered-belts less than 3 years old-SA helmet (NOT M).
Ask away-better now than in the tech line.

We changed from 4 displacement classes to 6 a couple years back. You must have found an old set of rules.
Translating road racing to hillclimbing:
Proper tire selection== nothing hooks up on moss or wet leaves.
Staying on the racing line==anything paved is considered good.

In P there are still 4. In U and SP there are 6 because we separated AWD and 2WD in the old top 2 classes.

Thanks,
Sounds like I'm on the right track (so to speak):
They are road legal tires.
I have a 2010 Helmet; which came with a fire suit, shoes gloves, and neck brace even if I don't need those.
I just installed new 5 point seat belt on the drivers side.
Installed a 5# ABC fire extinguisher with metal brackets. (on a cross bar of the roll cage behind and between the two front seats: will that pass? There's no room up front in this little car.
Correct: at 697 cc and a 0-60 of 20+ seconds, I don't think I'll be breaking any records.
Basically, the car is much safer than it would be as a stock, street legal daily driver.
Still time to tweak it.

Just looking forward to some safe fun intro to the sport and clubs, with hopes on progressing with this classic. It was a project of my Dad, now turning 80 and it will be a highlight for him to see it actually "compete."
Thanks again and any other thoughts or comments welcome.

I'd guess that you would be in class sp6.
If there is a cage, you need sfi rated roll bar padding any place your helmet might touch while you are seated.
Make sure you have a working horn. If no working horn, get a marine air horn and secure it within reach in the car. Otherwise it sounds like you are ready to go.
Do tech inspection Friday night, so if anything pops up, you'll have time deal with it. Don't be bashful to ask for help if you need it on site.

So long as that 2010 helmet is SA and not M it sounds like you should be about set. SP6 would be your class.

Seth pointed out the need for the SFI/FIA padding on your cage where your helmet may come in contact with it. It is not the same as the stuff more commonly used as pipe insulation that is often sold at speedshops as rollbar padding. The older stuff is still OK where your arms and legs may rest against the cage (in truth it doesnt do much good in an impact but is more comfortable to lean against than a bar). The SFI/FIA stuff is designed and certified to absorb helmet impacts and reduce the likelihood an impact with the cage would split the helmet and it feels quite hard. If you need to get the stuff online go here: http://www.rallylights.com/BSCI_Roll_Cage_Padding.aspx. You may want to call and speak with Dave (the owner) to get quicker service. At that site you will also see there is now a dual density version of the SFI stuff that Is useful where your arms and legs may lean against the cage and it is softer feeling than the regular SFI.

Ah! roll cage padding...didn't do that yet. Thanks for the link I'll check that out and get on it.
I did the excel sheet and it does seem I'm pretty solidly rated in the SP6 class.
The helmet is SA2010
The horn is working fine.
I have a cut-off switch for ignition; installed and clearly marked on the front right quarter near the windshield.
