How are .30 over and "very stock class" in the same description?

A muffler alone won't do anything for you.

Try posting what Is/Isn't allowed in your class, and we can go from there.

Circle tracks and circular logic go hand in hand....Thought you knew that.



What you want to do if circle track racing a 240 is this:

1 - Get a 4.3 or 4.6 ring gear for the rear end, and put it in the stock housing.
2 - Custom solid motor mounts to lower the engine and also move it a couple inches to the drivers side of the engine bay.
3 - Gut the bitch, and move whatever weight you have to keep over to the left side.
4 - rig up some brake ducting if you're on stock brakes, it helps a lot
5 - get rid of all the emissions crap and try to fab up a new intake that will get you some ram air action, make it as short a run as possible as well. In front of the radiator going through the stock battery location works well.

The good news is that our fuel pick up is on the right side, so you won't run into the same fuel starvation issues us road racers have.

okay sorry! should add some info. i bought the car with a full cage in it and it is gutted to the extreme. right now i am at the stage of patchin some of the frame where it has rotted away. i should have been more clear in my original post. these are the rules that we are aloud to run with

http://www.sunsetspeedway.ca/files/SunsetSpeedway2010MiniStockFinal.pdf

teh rear end gear in it is welded so i do not really wann tamper with that yo much. good call on brake ducts. and also ya. was wonderin if i cut out the front fender wells infront of the struts and rad mounts that wont weaken the car will it?

anything will hellp guys! thanks for the suggestions so far!

OK, so they're kinda restrictive... but there are things that are not mentioned that are within the rules and things above I spoke of that can also help out.

You're running the single cam right? The correct answer here is YES. Keep the stock exhaust manifold, and then run a 2.5'' pipe to the cheapest smallest muffler you can find, and keep the exhaust run short so you minimize weight in the exhaust.

You could use a 14'' wheel on the drivers side, and a 15'' wheel on the passenger side, and apparently you're allowed to push the offset out for the right front wheel. All of those will help the car turn left.

Try and keep the left side weight right on that 55% limit with you / fuel in the car.

No lead weight is allowed inside the car, but they don't say anything about suspension components being filled with lead.

Get that thing on some scales and see how close you are to the min weight of 2300lbs with driver. Preferably no fuel since that goes away during the race.


Clearly you don't want to exceed the rules too much in a stock class, but a little sand bagging is healthy in motorsport.

I agree, this will be an interesting build. you should get some pics of your cage up.

+1 to sleepy for helping out the new guy
