Taken from Randy's post on CompD
Ok sorry for the delay but as I stated before we have never changed a rule during the race season so it was hard for me to change stuff during the season.
We have talked to several competitors and since we have not had our first event we are going to make a rule revision for the following.

NHRDA Super Street Rule revision effective – February 1st 2012
» Fuel cells are permitted and do not have to be mounted in stock location ( Fuel cells must be SFI approved)
» Battery(s) are no longer required to be forward of OEM Firewall.

All other rules still apply

NHRDA Super-Street
S/S » Heads-Up class with a 4/10ths Pro Tree, Pro ladder by ET, Auto Start on
» 2wd Minimum weight: 5,000 lbs (w/ Driver) +/- 1%, slick tires permitted
» 4wd Minimum weight: 6,000 lbs (w/ Driver)+/- 1%, DOT approved tires required
» Tube chassis, back halved, 4-link, 3-link style rear suspension prohibited (Note: Traction/Ladder Bars allowed)
» Hood / Fender Stacks prohibited
» All Exhaust must exit up and away from vehicle
» Must have OEM style transmission (Note: Lenco, Liberty, Bruno, Clutchflite, Danco or similar prohibited)
» Engine must be forward of OEM Firewall

Thats 2 pretty big items IMHO that separated S/S from P/S. S/S was a class that was mainly modded street trucks, The battery and fuel cell rule kept the class pretty close to a street class. There are quite a few P/S trucks that can jump down to S/S if they didnt have a fuel cell so I bet we will now see a lot of that this season.

x2 i think its a poor decision... true street trucks do not run 9 second passes

I think these rules are fine either way. I don't think it will change anything really. Superstreet basically is wieght limit, DOT tires, no 4 links etc. Those are the real limitations. Putting the fuel tank/cell in the stock location or on the roof will make little difference.

Batteries....big deal. Maybe we'll see a 4000 lb 2wd adding 1,000lbs of batteries in the back. Oh well.

In any heads up class people will build it right up the limits of the rules. I'm not really sure how they would make it for "street trucks." The other rules didn't do that.

The word "street" in the class is being cried about too much IMO. Look at the NHRA. Oooooooh it has doors that open......and it runs 200+mph in the 1/4. So what.

That must be some sort of pressure cooker for gumbo if I know Stelly!

The new rules don't mean squat in stopping the class being race trucks. The rule was like this years ago and people whined that is was not a street class. I told Randy this change wouldn't slow anyone down and ran 9.3/9.4's with a battery in the front and cell under the bed. All that rule did was make it harder to setup the suspension correctly.

I support any rule changes that get more trucks into racing period. I also agree that Pro street and Super street and very close classes with the fast Super Street trucks running as fast as 95% of the Pro Street. Not sure what the best idea is for that yet.

would not allowing cheater slicks and drag radials in SS make a difference. I think it might. But the limiter here is the Pro Street trucks facing driveline issues I think. Find more reliable driveline and prostreet will be faster, right?

Not following you, what drive line issues are you referring to? If you took away drag radials and cheater slicks, it would probably slow down the SS trucks some. I think it would be more dangerous, guys would race tires like Proxies which are not rated for these heavy trucks, and some tracks like Sacramento really look at that stuff. Also running regular street tires on these high HP trucks would really rip up the groove on the track. Bad idea in my opinion. Best advice is if you don't think you can compete in SS with your truck, back down the power a little and race 11.90. That's what I did and it's more fun then SS, requires more driving skills and is a hell of a lot easier on your truck.

Both Verlon and I drove our trucks to the finals in Topeka last year and drove them back home (over 3400 miles for me) and I'm sure there were others who did as well. I don't remember one 11.90 truck breaking in at the world finals.

I took my truck down the Sacramento to race in Fred's Truck Drags in October, turned up the power and scattered the tranny on the second pass. I trailered down for just that possibility.

If you really want to make a difference in the Super Street Class, rule they have to be street legal, and have a current licence.

I'm glad they changed it! Thought it was dumb rule to begin with and it bumped me to Pro street when I first started racing diesels because my certified fuel cell was ina different location

I'll never go back to ss now as I've gone to far but I'm not a good pro street candidate either:(

I agree with you that the 11.90 class a great alternative for guys who can't compete in SS, however, I don't agree with you on the tire issue. Toyo Proxies are a load range C tire and are more than capable of carrying a 6000-7000 lb truck down the 1/4 mile or street driving for thousands of miles or towing 10k lbs...I know, Ive done it. what IS NOT as safe is drag radials and cheater slicks that are in fact rated for a car's weight and not that of a 6000lb truck. several blowouts, some to members of this forum, have proven this.

As far as the driveline issues, it seems to me that transmission failures and resulting cost of finding better options are the reasons Pro Street trucks have not gotten a lot faster in the last 2 years, whereas Super Street trucks have overcome one or more seconds of ET in just the last two years.

Just my observations..

I think the driveline should be more dependable with the lighter weight of the Pro Street, but nothing is very dependable at those HP levels.

I like running in Super Street trim and then racing in Pro Street also, but the cost per pass is getting quite out of hand when running both. This is why I picked up a light weight ride for Pro Stock, 1/2 the weight and less HP = more bang for the buck and a faster ET.

Rob, That's exactly what class structure is meant to do in almost any motorsport - encourage people to move up in class. I think it has worked halfway decent in the NHRDA and NADM and other big diesel associations. But it all starts with the right rules for a class, that's what can make or break attendance in the first place.

I am 100% sure what the best idea is;)
