Top Dragster rules for 07

AA Altered · 05-09-2007, 08:37 AM

Has anyone noticed the discrepency between the NHRA rulebook and the top dragster rules (as posted in DIV 5)?

There are many but for sepercharged front motor cars, a SFI 15 suit is required for Comp or S/C but in T/D they want a 20.

In Comp or S/C supercharger restrainsts 14-1 (straps only) are required and in T/D they want the 14-2 (bag).

I'm always one for safety, but it seems odd that I can run the same car, same speed and same ET in either Comp or S/C with lesser (and less expensive) safety equipment but if I move over to T/D, I need the expensive stuff.

I know most cars in the class are dragsters with large displacement normally aspirated motors but blowers and shorter wheelbases are so much more fun - at least for me.

Division 5 has changed the blower restraint requirement but not the suit as far as I know.

Any comments?

Tony: the way I figured it to be is that a S/C car is running 8.90... we all know the car could run much faster but the class is 8.90... as for comp, depends on the index..

in T/D some of the Blown Altereds I have seen run are well into the 6's.. fall well under the requirements for Advanced E.T, where NHRA clearly required more equipment...

I have a Altered myself and was thinking of trying T/D but my car is only Certified to 7.50 and the class has a 7.99 minimum...

That's agood point. Our car could run in the low 7's and maybe the 6's with enough overdrive. We set it up to run on the Nostalgia Eliminator I class with the 7.60 index, over the 7.50 line for more safety equipment. My point to our Tech Director was to make the limit for T/D consistent with the rule bood at 7.50.

Either that or set the max ET at 7.50.

I'm not trying to beat a dead horse here. I never begrudge the idea of using safety equipment. I just want NHRA to be consistent.

As an aside my understaqnding is that lifter the T/D and T/S rules from IHRA.

I think NHRA set the min Et at 7.99 only because it would keep alot of the cars in S/C.. if they set it at the 8.50 they originally had for T/S when they started it you would have everyone running T/D and no one in S/C.. the 7.99 min is not going to be run by the average S/C car.. 8.1's maybe..

I can tell you this much from what I have seen it wont be long before you will need a 7.30 car or faster just to get in the show..
