Mike Moran is the only guy i've personally seen running a turbo car in the ProMod class, and he didnt' really have that much success but he didn't have all that much track time either with the car. anyways, here are the rules, should be SWEET to see some bad *** turbo cars running. 500+ci, twin 91s, and 2700# should be NASTY.

These systems must be open loop design and may only monitor and/or be affected by engine functions such as rpm, airflow, air temperature, etc. The EFI and ignition systems may not be affected by, controlled by, or connected (either directly or indirectly) to any devices that monitor any vehicle performance data such as wheel speed, driveshaft speed, etc.

Yes, which is pointless because how do you define "traction control"? If say DFI came out with a firmware update that let you define a maximum rate of accelleration in rpm/s in an obscure dialog box that was say only available via secret hotkey combination how would you police that? You absolutely can't. Its frutile. At ProMod levels advances in traction control are as much an advance in safety as say beadlock wheels and it makes for safer and closer racing than smoke shows and centerline crossing.
You still have to be able to adjust and maintain your equipment to be competitive. As a non-profit racer's association NHRA is doing little to promote advancement and technology that the supporting aftermarket companies need to remain competitive and be able to sponsor the series. The competition department needs some new younger blood.

I have no idea why its such a big deal, wideband controlled closed loop fueling has been around for a long time, its readily available, isnt that expensive and can save money in the long run and has nothing to do with traction control.
I think NHRA is protecting its present sponsors (and racers) that arent really involved in the fuel injection game.

There's been some talk on the comp plus forum about this device. Some of the talk centers around the fact that its not illegal to use in TESTING. Its small enough to be carried in your fire suit, which makes it even harder to find. Some people are saying there are competitors using it right now in competition. As far as turbos in pro mod, nobody has been running them in either IHRA or NHRA they havent been allowed til now. There has been at least a couple in the ADRA, Mike Moran, Annette Summer.
As far as EFI and technology in the NHRA, They're afraid of not being able to find this stuff, or not being able to prove that someone is or is not using this technology. Plus, with no limit on spending (cap) they're also afraid of what has happened to F1. Nobody wants that.
As long as the vahicles are controlled mechanically, you dont need an electronics specialist to "tech" the cars, along with everything else that needs to be passed thru (tech)

NHRA pro mods are eh
I'd like to see NHRA find a ticket to the 21st. century and have EFI pro stock, 6.0 LSX vs. 5.4 4V vs. 6.1 Hemi.
Isn't this how P/S started? The best modded factory motors squaring off?

Nowadays, Superstock is closer to the original Pro stock than Pro stock is. Kinda like NASCAR being "stock" cars..lol

NHRA let a procharged car run in comp last year, forget his name, but he did very well so we'll se how long that lasts.

Actually KP the Procharged car is Bo Butners and he won the championship with it. The index was 8.15 and he was running 7 teens riding the brakes at the finish line. NHRA screwed the pooch on theat class. The class didnt even have the right chassis certification attached to it. Next year the class is getting hit hard and it will be another class like AA/AT with nobody running it.
As for traction control most everyone has some sort on there cars now. The turbo guys wont have much advantage there. The advantage is the power they are capable of making.

I see tracton control (especially on a turbo car) as more of a safety item, the better systems can monitor the car the whole way down the track and if its starts cutting the tires loose mid track it can back it off. Same with closed loop fueling, why not do your best to prevent them from blowing up in the first place instead of band aiding it with a diaper.

But what gets me is they go all out for the turbo/injected 'sport compact' cars yet leave most of the newer EFI V8 stuff out. Go ahead and give people a class where they can run a late model V8 with the lastest and greatest EFI/forced induction combos in featherweight cars like the 'sport compact' cars and see what happens

I agree KP. I dont understand the thinking of NHRA and EFI except when your 2 biggest sponsors are Holley and Barry Grant NHRA is scared to rock the boat.
Now Comp is becoming more EFI oriented so maybe it will roll into Pro Stock someday.
