upright 600's
 

I have recently been looking into purchasing a mini sprint and have a few questions. First i was woundering if anyone could tell me if I got a car where the motor sits between the frame rails, would it be a big disadvantage over the offset motors in 600cc racing? Also could I use the same car with different motors for both 600cc races, as well as 1000cc races?

Re: upright 600's
 

You are correct. If you purchase an upright mini sprint you can run either a 600cc or 1000cc engine. The only point to be careful of is the diameter of the tubing. Most upright mini sprints should be legal as a 600 or 1000, however there were a few cars built several years ago that were built out of smaller diameter, lighter tubing that can only be run as a 600 car.

thank you Motorsportspr,
Also I was wondering when running with the 600's would not having the offset motor be much of a disadvantage?

Make sure that you understand the difference between an upright and a modified midget or sidewinder. The modified midget has the motor offset and the driver sits with his legs straight out in front of him. The mini sprint is like a midget with the engine more centered and the drivers legs underneath (more like sitting on a bar stool).

There are very few places where the upright mini sprints and the modified midgets run together. In some cases a modified midget organization will allow an upright to run with them, however modified midgets have not been allowed to run with the uprights. The modified midget is smaller and lighter, however out west there is an organization where the two run together and the upright has won races.

Make sure you understand what is running in your area. There has been more than one case where someone has purchased a modified midget, thinking that they had an upright mini sprint - only to be disappointed that there was no where to run the modified midget locally.

If you are in the Ohio/Indiana area the upright mini sprint is probably the best choice. There are plenty of places to run as either a 600 or 1000.

so what is the difference between a modified midget with a 600, and a micro sprint with a 600? or is it just a terminology thing?

They are the same thing. Modified Midgets are as motorsportspr said, Offset engines with the driver sitting on the floor with the legs stretched out. They are also slightly smaller weighing aroun 700 lbs. The run a 12 sq ft wing also. They are also called Micros and sidewinders depending on the part of the country.

Upright mini sprints use basically a midget chassis capable of housing a motorcycle engine. The driver sits upright in the car with the motor directly infront. They use often the same wheels, tires, suspension components, and shocks as a full midget. They use a 16 sq ft wing.They are run with 600cc, 750cc, 1000cc, and 1200cc, though in this region you will just see 600's and 1000's/1200's. The tubing is sometimes slightly smaller than that of a midget, depending on the manufacturer. FOZ race cars, ERC, Henchcraft, and Baily are all leaders in manufacturing upright mini sprints.

Where are you from or planning on running?That would be the first question.

Re: upright 600's
 

Well I would mostly be running with the MMSA, or the AMSA. Just thought I might want a 600 to start with because I think Salem runs them every friday if I am correct, and that would be close to home.

So that leads me to the next question ... I see MMSA and AMSA are both on the new Twin Cities schedule, whats the difference in rules, etc between the two ? thank you

AMSA allows more open rules, can run 1200's, have to weigh 940 if your car is a 1200 or run alcohol(IDK why?) and 900 if it is a 1000cc. Pays $500 to win $50 to start. MMSA is a strictly stock series, must be 1000cc or less, have to weigh atleast 900. Pays $1000 to win, $100 to start. I think MMSA has a slightly higher membership fee. Both websites have a complete list of rules, most are generally the same besides the motor rule.
