Class questions

[Calpantera]

OK total noob here guys so bear with me. Not even sure if this is the right place to post this question but here goes.
Would the car in the attached pic run in streamliner because it is a purpose built race car with covered wheels or would it be lakester. I know it would not be very competitive as the body style produces lot of downforce and that is just wasted power in a staight line, but we are looking to just get in the game initially and figure we can use it to license and get a 150, then once we get the bug we will want to get competitive. We already know how to make the power.

Additionally does anyone know of any LSR Mazda Miatas running out there? Would a Miata run as a roadster or a sports?
I read some conflicting info in the SCTA site so I am waiting on my rule book in the mail and hope that clears them up.

Thank you for any information you can provide

Streamliner, covered wheels.

Study the rules thoroughly before making big plans for this car in LSR, particularly roll cage area........

Not to discourage you but often it is faster, easier, and less expensive to build a special construction [liner, lakester] as well as cars in some other classes to the safety rules from scratch.

The reason I was thinking about using it in a class at all is that I have heard that you get a lot more runs in at an event when running in a class as opposed to running just for speed. I will go over the rules more once I get the rule book.
Eventually the goal for the team is to build up a J/BGMS and also run it in G/GMS, at least that is the initial thought.

Thanks for the input.

Bill, welcome to our addiction
You sound like a perfect candidate for World of Speed.  I think you can do 130 or 150 club with that car.  Might want to go to the USFRA website and read the rules for the clubs.  150 club runs on the record course, 130 club on a 1 mile course.  
When you get your scta rulebook you will see your car will need a lot of work to make it legal to run at any scta event.  
Both clubs will get you all the salt time you need to decide that you are going to build something.
The Miata would be a GT or Modified Sports depending on what you do....
Roadsters are old cars (1923 to 1938).... even if they are brand new

you should attend Speedweek to get the feel, then WoS to run the clubs.  Stop in and talk, best racing you will find

"...I have heard that you get a lot more runs in at an event when running in a class as opposed to running just for speed."

Every entry is given the same opportunity for runs as wanted. It is first come-first served at the starting line. Your consultant is giving you some bum info.

The pictured car would be very, very difficult to convert to class specs. First would have to be a roll cage to spec. The chassis that these cars use is not compliant with the rules. Depending on engine class the car must be built to the existing record where chassis, tires, fire system, etc. is concerned.

When you recieve your rulebook you will see that there is no J engine break in the Modified Sports classes, so you can save that exercise.

From your posts I will guess that you are planning on the G engine class. Here are some samples of of salt records:

Of course, if you plan on the USFRA 130/150 club events the records don't matter. Keep asking questions, I am sure you will find the folks here eager to help.

A Miata would run in the GT class, provided the windshield is still there, along with the headlights, horn and tail lights, and the body is stock, including the gas tank.

Yup - get the rule book, and welcome aboard!

[Calpantera]

Once you are in a modified class you no longer have to run the stock engine correct? I have a hell of a powerplant that right now is just under 700cc, I would like to run it in a BGMS class but they only go down to 750cc engine class. How do they create a new class? Is it by demand or some other method?

Thanks agin

[nrhs sales]

They don't create a new class!

[dw230]

Production class entries run modified engines also. Basic requirements for production classes, besides the body mentioned in the other post, include the engine being an available option for the body used. Internal modifications have no effect on class. The production engine can be increased in displacement to run up class, you must run in the displacement class you have entered. A smaller engine cannot compete in a larger engine class.

The J engine break for Modified Sports has been brought to the rules committee for the last two years and has not made the cut. You can run your 700cc engine a production vehicle if it came in said car.

You would just run in the 750cc class. It is for engines from 501cc to 750ccs

Rich, that would be J/BGMS- I'm not seeing it, but my current book is with my welder.  Does it exist? Are you thinking I/BGMS - 750-1000?  Can you go smaller?

[Stainless1]

Get that motor to 760cc, then it runs I, the one liter class.

[Calpantera]

Hmm.. now that leads me to another question. Don't most builders go for the upper limit in their engine class, like build out to 99% of the volume allowed in the class? Leaving a little breathing room of course in case your calculations and the tech calcs are off by a bit. It would seem to me that if you are going for a class record you are going to take advantage of everything you can so if I were to run in "I" then I would want to build a one liter right (995cc or so)?

[Milwaukee Midget]

You catch on quick.

From reply #4
"When you recieve your rulebook you will see that there is no J engine break in the Modified Sports classes, so you can save that exercise."

Sometimes building to max. displacement does not yield max. performance. I think some research into bore/stroke combinations would help.
