Ez plate system

[X-TECH MAN]

This would sure get rid of those expensive mega motors and cars running 30-40 MPH faster than they should be for the et. You would accually see a heads up side by side race with out the stumble. Maybe the spectators would watch again.

Long time ago the e.t break here was 8.00 1/8th mile. Tracks let you run both classes. We used restrictor plates to slow down to 7.90's so we could run both. There are tricks to running a plate for consistency though. I can't tell you may want to try one again.

I have seen guys running that system in the NHRA Unleashed index classes with good results. For people with carburetors, it looks like a simple way to adjust ET.

Again with the crap about the super classes? Really? What do you care anyway? Do you even race a super class? We are NOT going to attract more spectators with changes to the super classes. Look at Norwalk, they have the very same classes every other division race has and they have a packed house. Because they know how to promote a race! I cracks me up that some people think that if we get rid of throttle stops then "POOF" the spectators will appear. Sorry that isn't going to happen! Most spectators want to watch something loud and fast, which super classes are neither. That is why the stands are packed for the fuel classes at a National. Most fans don't know enough about the cars to enjoy watching anything but the loud and fast cars. If you want to talk about a confusing class, what about comp. Try once to explain that to an average spectator.

Although I would like to see more fans at the races, I am there for me not the fans. If NHRA ever figures out how to promote like Bader does maybe we will start to have some fans at the division races. Until then, stop trying to change around the classes to suit your interests.

Ryan,
You are correct about promotion of races(or lack of it) , but you have named the wrong party being responsible of promoting Divisional events. A NHRA or IHRA race is a product "Sold" to the owners of the race track. It is not IHRA or NHRA's responsibility to promote the race. (Now there may be some clause in the contract about ads in the organizations "House" magazines) The "Product" they sell is the race. Some track owners are great promoters and use the "product" to attract fans/spectators to the event. Other track owners or managers only care about making money off the racers that attend the race. So don't knock either IHRA or NHRA for the lack of spectators at any divisional event.
There is a break even or "Crack the nut" point based only on car count. Any car count over that point is on the + side of the ledger for the track owners.
I have always considered spectators as the real profit center of the race.
The Baders know the product and they also know how to promote it to their market. There are others like the Baders , but there are many that have no idea how to fill the stands or just take the easy way out and settle for making money off the racers.

could not have said it better myself. let me also add that there are non-throttle stop classes that do not resonate with fans. look at pro stock bike. when those guys pull up to the box the crowd runs like plague.

when running a 4150 carb, there is no better than the adjustable restrictor plate manufactured by Willys and sold through Summit, Jegs and others.

Been using this plate since 2008. Previously to slow my 9 second Chevelle to 10.0 and since 2009 to slow my 8 second Firebird to 9.0 enabling me to run 9.0x all season long at every track I compete.



This 1" 4 hole plate has 18 turns of adjustment in it from fully open 1.75" bore(s) to 1.00"

Each turn is worth ~.04 and can easily kill 100HP.

Nothing to take apart or swap out, couldn't be easier or simplier. Adjustment(s) take a few seconds and as Rich has stated, infinitely adjustable.

Several competitiors and friends are now using it on their 8 to 11 second rides to slow them to make ET cutoffs and/or index classes as well I know of 1 former Division 1 Super Street Champion now using it after hearing about and seeing it in use on my car.

If you turn it in 3 or so turns, do you have to lean out the carb to make up for the reduced air flow ?

[1320racer]

No, I never touch the jetting.
