after a meeting with NHRA chassis inspectors sat. evening I have seen that that the rules makers are quite confused. I am in the process of building one of their 25.5 cages and this is getting ridiculous. Just the backhalf from the main hoop rearward took 2 days. NHRA is making this to be out of our price range. Mind you I added some bars that are not required for rigidity but the extra bars are not needed.

I am to assume you are speaking of a F-body style vehicle. What is a ballpark price on something of this nature? That is good to 7.50's correct.

Good to know, my car gets 25.5'd the end of this month. Which bars are not necessary?

MADMAN

I put 4 small bars from the cage to the shock crossmember to strenghten the shock mount area. This car has coilovers on it so all the load is on the shock mount.

Try doing a 25.2 with stock floors if you think the 25.5 is bad

truthfully the 25.2 rule doesnt even require the rear framerails. Only the 25.5. That was my argument with NHRA.

I am doing a 25.2 also in a stock floor car.

Outlaw

thats lame... got to love SFI specs! hahahah

Shoot the pictures of the 25.2 when you get to a point.. i would love to see it!!

BTW nice job on the cage above.. looks good!

What's the ballpark for a 25.5 setup? Just need something good to 7.5's...for future reference.

I think the NHRA has serious issues with the 10.5" tire cars. They are trying to cover their asses and make is to expensive to build a nontube chassis car.

The days of the $3000.00 cages are gone. The 25.5 is looking like a $7000.00 job. I will know more once I have finished this one. I also know that alot of my chassis stuff will have to be changed to meet the rules.

freaking great.....so are we any safer with all the new stuff or are htey just bing ****** about the whole thing?

i dno't blame the NHRA if they are trying to cover their asses regarding 10.5" tire racing because by covering their asses it is making the racer safer. if you can't afford to play the game then maybe you need to find a different game to play. 10.5" tire racing is dangerous or most of those competing at a high level. that much power and that small of a tire is not a good combo on some occasions.

Yes at 250mph the car would be safer. Actually the crumple zones that are built in the cars that are to absorb impact are being strengthened.


tha bad part is that these cages are required but the tech on other parts of the car is suffering.

I agree about the tech issue. The local tracks here don't even know how to spell tech! We don't even have scales at the track to check the cars as they come off the track.

The 10.5 cars are getting faster and faster. the last 10.5W outlaw race saw a new record in et. twin turbo mustang went 4.45 and backed it up with two more 4.4X passes. We just got a Z back that we had 25.5 and we spent nearly 10k. We added a few other things here and there. Looks nice though.

"i dno't blame the NHRA if they are trying to cover their asses regarding 10.5" tire racing because by covering their asses it is making the racer safer."

-I agree with making the racing safer...but look at some of the scrap you will see at your local track running low 9's to high 8's.

I love lining up next to the Hero with Two stages of nitrous, worn slicks, metric radials, the wrong wheel studs, no parachute, and improper driver safety gear... but his chassis is 25.5 legal.

If safety is their main priority they should not let anything slide. I would guess that over 50% of cars are illegal for the MPH and ET they run.

I am waiting for the day when they start limiting MPH by tire size.

Sounds about right.I'm having the updated 25.5 being done now.

Maggie

Amen to that!!
What often happens is that to win races builders have to be very good at looking for advantages that come from what is NOT covered in the rule book. Unfortunately saftey is often compromised.

I hear ya on that...I'm starting to think it's time for me to retire!
I'm in the process of costing a 25.5 out now and you know something...? $7000.00 is starting to look like a bargain!!

Here is the recommended way for the inner framerails to run under the car. The driver side is done with clearance for the 2" KOOKs headers.


Also this our midplate setup with the front strut bars installed. The midplate bar is also considered our dash bar that is required for the 25.5.
