(Amendments noted in Orange -6/19/11)

General : TSR is a class designed for everyone! With a NO LIMIT on turbo, No restriction on Engine, No restriction on Trans, No restrictions on rear ends, pretty much allows anyone and everyone to be able to have a class to race in with as minimal restrictions as possible. You will have the stage engine guy's on street tires that won't be able to launch or use the trans brake like the guy's with the drag radials and trans brakes! this should make for some pretty neat racing...

Scott,
If Clint gives me the ok, I would like to have this class at Reynold's.

Tsr

After starting this class last year and seeing the decent car count we had for the very first race it was almost sad to see this class be left back so with the advice from others on starting it back up I decided to start it up again but this time with a new twist. The twist is, now all THS cars that competed last year will fit into TSR this year. Not to leave out the True street tire cars I will personally give away prizes to the fastest car on street tires (Not a Drag Radial) plus this class has picked up new sponsorship for the 2011 season. We look forward to having you all race with us and have a great year of winning some decent Cash money & prizes

Clay,
The turbo check is real easy. Just pull the MAF pipe off and someone will measure the compressor opening. If you want to run your other turbo, it looks like you may need to swap covers. This is still way, way cheaper and easier than converting it to a THS turbo. That requires sending the turbo in and getting a new backing plate and cover.

The ported shroud turbo was an oversight in the rules by me and it should be allowed. with that being said and this the starting of the new race year and no races have ran yet I will gladly change that rule and allow the ported shrouds. Just trying to make things easier for the racers!


Scot W.
RRA for TSR

Quick answer, YES!

Shouldnt be a problem to add TSR to the Reynolds schedule. Should be a great addition to all the other race classes, just more fun for everyone!!

That is what it is all about...

would be great if my car would fit into this class? ie;my tank,fuel lines,etc??
