I have already made my point where the tranny thing is concerned. I think that there are valid points on both sides of this coin. HOWEVER the one thing that should be said for the imca, is the freedom that it affords.
Look around. We can take our cars to hundreds of tracks from California to S. Carolina and all in between and race any Friday, Saturday, or Sunday from February through December with minimal rule changes. There is one tire, so there is little tire advantage, the same "basic" rules apply with little differences from track to track.
Can street stocks or sprint cars say the same? Not hardly. Every track has a different view on what a street stock and a Super Street stock should be. We are so spoiled at this point that we don't see where all this bickering and fussing over tranny rules and claim rules is headed. I think that once in a while, we need to just be thankful that we can go anywhere at most anytime and be able to race our cars and have fun doing my opinion, that's the bottom line.

Modracr41 you hit it again!!! The sole reason for me migrating to the IMCA class, and several others over this winter, is to be able to run at almost any track out there without major rule changes, etc. My street stock was only truly legal at a couple local tracks, but severly handicapped at many others due to the variance of rule changes. Heck, had to keep (2) totally different sets of tires mounted, (2) complete intake setups, spare carbs, etc., handy just to compete at another track and be within the rule limits and be competitive. Why would anyone consider breaking down a uniform system that works or supports continual changes to make it darn near impossible to travel and race other facilities? Just my couple cents.

I just wanted to know why the 4000 dollar trans is an advantage over the glide or the muncie. I have never herd of these, and if they run a 5.5 clutch they must be realy light and strong.The brinn I have seen before and see an advantage with no cluth on the crank.Just trying to understand this post a little more

prices rarely come down in the racing world. here is a list of what i have spent 6 yrs ago when i built my first mod.

2 disc clutch q master $485 then
had to have their flywheel $85
hyd t bearing $130
at least 1 clutch pack a year $100
lakewood scattershield $225
3 speed lightened first removed did myself but guessing cost would be about $300 maybe more
total is $1225. i would like to have had the choice of a $1,500 bert/brinn
wher i could run a coupler and a stock $25 alum bellhousing. now i had run autos but whent manual after breaking many autos in a short time. i just wish i had the choice to run what i want in IMCA when it comes to a durable unit. heck you cant hardly find the junkyard parts that most the rules were written for. most yards dont have the older 3 spds or powerglides anymore if they do it costs more because of the demand for them. people ask more for used parts at swapmeets for the same reason.

The advantage of the Layne is that the clutch does not turn when the unit is in high gear. Layne has a tranny dyno and they claim that their unit only uses 2hp in high compared to 25hp for glides and 70hp for muncies. The new rule about clutch being attached to the crankshaft will even things somewhat but you can bet that the guys at Layne are building a better mousetrap as we speak. Their stuff was designed for racing and doesn't break. The only difference is they have put it in a stock case. the case is the whole issue. There are guys running Brinn's inside of powerglide cases to get around this goofy rule. We could all be running aftermarket tranny for less than we spend on the tilton 5.5 stuff, never mind the transmission you put behind it.

I have owned a modified for 10 years. Over those 10 years, we have run at tracks with open rules, UMP rules, and most recently, IMCA rules. I have run Muncie's, Brinns, and Powerglides. When our track went IMCA this past year, I went to Powerglides. The new Powerglide was about $ 950.00 with hardened shaft, coupler, and ring gear shield. I also bought a spare because of the case problems with Powerglides, add $ 650.00. We ran a 377 with about 500 hp. We broke one transmission with two nights left in the season. We broke the second transmission at Boone two weeks before the Nationals. We went to see if we could run with the Iowa cars. I must admit, the second transmission broke because the weld on the front of the driveshaft broke, which shook the transmission, and broke the case. Never the less, I am in need of having two transmissions repaired.

The three years prior to IMCA, we ran open rules with a Brinn transmission. I paid $1250.00 plus $25.00 for an aluminum bell housing. We ran this transmission for three seasons only changing the oil every three nights. One night my car was involved in an accident where another car hit my car so hard, it broke the rearend housing. It also broke the bell housing to where the Brinn transmission was hanging in the car by only the shifter. Damage to the transmission was one bruse on the tailshaft housing, and broken tit on the imput shaft that rides in the pilot bushing. We went on to race the transmission another year.

After my three years of use, I sold the transmission for $ 800.00. The guy I sold it to, ran it another season, winning a track championship. At the end of that year he changed the clutches and went on to run the transmission another year. He plans to run it this coming season also. That is 5 years of service with only 1 clutch pack and no other maintenance. Sad, I cannot say the same for my Powerglides.

Allow Brinns and Berts, make the tires a harder compound, and there will be no need for an engine claim or transmission claim. The class will cost less, because there will be less to police.

Modifieds are the most popular class in this area. When the latemodels have a show paying $ 10,000.00 to win, and run the modifieds as a support class at $ 500.00 or $ 1000.00, we end up with 30 to 40 latemodels, and 50 to 70 modifieds.

Lakewood bellhousing $250
5.5" Triple disc clutch $750
Reworked alum. muncie trans. $500
Being able to race IMCA, "Priceless" LOL[IMG][/IMG
In all reality, how many guys run IMCA anymore? I didn't even buy a license this year, but my car is still IMCA legal. IMCA started in Iowa 20 years ago and 90% of the tracks are not sanctioned any more. Almost all of the other tracks let the Bert & Brinn run, but they have to add weight. I think the trend is going towards the Bert & Brinn but its going to take some time to get compliance with everyone. Just my 2 pennies.

I think we should be run bert or brinn transmissions already. I agree when your in the feature the last thing you need to worry about is your tranny not holding up. I think the bert and brinn trannys are a lot more durable. Just my 2 cents.
