Doh a friend pointed this out to me on the phone today, trans brakes are prohibited? Hmmmmm.

The trans brake deal is pretty stupid. I dont run one, but I know people that do. That is a bunch of ****!

All that looks to be the same as last year. Is the trans brake rule new this year?

Just spoke to some of the tech guys here about this issue. The rule has been added to keep the playing field level. They feel that if trans brakes are allowed it could easily mean a proliferation of these type cars/devices in the class, which could alienate the footbrake guys who make up the majority of the class – forcing them to either step up and buy more junk to be competitive, or just give up. Also from a technical perspective, it helps the process by not having to spend a bunch of time trying to figure out if the wires attached to the thing are there for the intended purpose, or perhaps branch out into something -- uhm -- else.
If you have one on your car, you can still race, but it will be required to be inoperable and verified by the tech folk at the event.

What do you do with a TCI trans brake like mine that you have to use for reverse? Just dont park where you have to back up I guess lol.

No offense Scott but allowing 8.50 cars and not allowing trans brakes is ridiculous IMO If these types of cars arent what you want in the class limit the ET to 10.0 or something for the showdown..

LOL.. No offense taken KP as I am just the messenger, but I'll make sure the guys here understand where those of you with faster cars are coming from. It does present a quandary for sure.

I can understand why you guys dont want faster or more race oriented cars in that class. Why not split the index class, maybe 8.50-10.00 as a 'fast' index class and let trans brakes in. You could even get creative and run the faster index class last and let the 1st round losers of DR and all motor run it if they make it back to the lanes in time. That way you arent taking cars out of heads up classes to run the faster index if they are thinking of bailing out because they arent quick enough.

Leave 10.00 and slower foot brake only, be easier to ladder also, I dont know why I wasted my time qualifying when there was no ladder lol, C16 is expensive and I could have slept a couple more hours.

Not to mention it will be a lot better from a spectator point of view since the cars are a little closer together ET-wise. Plus easier to manage the staging lanes as well with the faster cars separated from the slower ones when called.

Just rambling, I know it probably wont change but it sure would be nice to give the in between cars a decent class..

I'll need to go back over the number of entries again. I know I posted it somewhere here last year -- breaking down the car count by et. This way I can see how the numbers stack up and then let the others take a look at it.

Here is the thread:

http://www.ls1tech.com/forums/showth...ght=9.00+index

Here is what you posted a while back:

9.00 -- 2
9.50 -- 1
10.0 -- 7
10.5 -- 5
11.0 -- 10
11.5 -- 11
12.0 -- 13
12.5 -- 4
13.0 -- 4
13.5 -- 3
14.0 -- 5

I changed it since you missed the one 9.50 car.

If you went 10.5-8.50 thats 15 cars, which still is more than either DR or all motor had. DR had 12 cars qualified and All motor had 6 cars..

There are qite a few cars in the mid/high 8s and low/mid 9s that just arent going to take a chance in DR. And thats a shame because they represent cars that are usually home built and have a heck of a lot of time and money invested to be lumped in with 13 second cars and their ***** cut off with no trans brake allowed.

But then again maybe no one cares

Thanks Kevin. I'll run it up the flagpole. And before you DR guys get all in a "splitting the class" twist -- understand that there are a heck of a lot more cars we are talking about here -- also -- this is only an idea. I doubt anything will come of it, but I'll make sure it's at least considered.

Thats cool Scott, I know everyone is reluctant to change anything since it was somewhat successful last year. But there is always room for improvement and non drastic changes.

I can see both sides on this, but keep in mind the EFI class is the closest one that makes the regular tour to the LSX index class with a 5 tenths pro tree and preset half second indexes, and there are no transbrakes allowed in it either.

Late model EFI also includes Vipers, Mustangs and whatnot, the LSX index race does not so I dont see what that has to do with anything there are index races all across the country running every weekind so it sure isnt anything novel..

FWIW Late Model EFI allowed trans brakes last year, and guess what a 13 second footbrake car won the championship. And John cut some pretty damn good lights as well. If you have a car that can red light on a .500 pro tree (like mine) its harder to cut a good light with no delay box so I dont see the big deal about the trans brakes, it goes both ways. On a .400 tree there would most definately be an advantage but its not a .400 so its moot.

Well I won the index class last year, with a foot brake 11.50 car, and I raced a few faster Tbrake cars.....


So obviously it can be done with a foot brake car vs. t-brake cars.


Hi Scott Have ya missed me? lol

Kevin,

I understand your point, and I didn't read last year's rulebook so my fault there. Just trying to see where NMCA's viewpoint is coming from. I know Open Comp allows them on the 5 tenths pro tree, but again that's everything from old cars to new cars.

Derek

I know, I'm just saying that last year trans brakes were allowed in both the LSX race and late model EFI and both were won by slower footbrake cars.

Around here in footbrake you arent supposed to have a trans that shifts by itself since thats an advantage over manual trans and older autos. IMO cutting a decent light on a .500 tree with a 12 second car isnt an issue but the consistancy of leaving a 4L60 in drive is a much bigger advantage than a 9 second trans brake/manual shifted auto or the poor stick shift guys IMO. Even though I notice I could run an airshifter and footbrake which would help me more than the trans brake, my car runs just fine off the footbrake but I'm not going to glaze over my direct clutches trying to back it up because they make me disconnect the TB solenoid. Honestly I run downtrack timing retards to slow the car up to where I want it, I can either start them with the trans brake solenoid or with the brake light switch so not allowing a brake doesnt help that at all. And since there is no external boxes you really cant police that.. But in the end the trans brake, all the fancy electronics and consistancy in the world doesnt help when the driver shifts from first to third lol.

But IMO the best solution would be a 'fast' and 'slow' bracket class instead of lumping 8.50-14.00 second cars together which makes for some pretty lopsided and confusng racing to say the least when 64 cars show up for 1st round. I'll even bitch a little about how much it sucks to be strapped in a low 9 second car waiting in the staging lanes with 80 other cars to make a pass starting it up and rolling up a few feet ever 10 minutes on a sunny 80 degree day, big difference between that and sitting there waiting in jeans and a t-shirt in a stockish car

Or even just make one 8.50 to 9.50 heads up index class for the faster cars that cant run DR. In reality the showdown class really isnt an index race, its a bracket race with dial ins set at .5 second intervals. An index race would be all cars running the same ET like I do almost every weekend (6.0 1/8 mile index is where I have been racing mostly) but I'm sure they do that just to make it sound slightly different than the regular bracket race they run and open comp.

Either way if they just want a bunch of 11-14 second street cars for the showdown dont put on a facade by allowing 8.50 cars in and then say you cant run a trans brake and you really dont want any of that 'type' of car running in that class. How many footbrake 8.50 1/4 mile cars are out there in any class..

FWIW I'm just giving some observations, everyone said 'come on down' and we'll adjust the rules next year when we see how it goes and who shows up. Only thing I seen changed was they now dont allow trans brakes in the index class and a trans brake car didnt even win, and they now have a 8.50 index. They told the nitrous guys to 'come on down' and they did, and they didnt change anything much in DR. The 'come on down' thing works once, maybe twice but for what it costs to travel these days and race I doubt it will work many times
