5.49 or faster needs something beyond an 8.50 cage last time I checked.

 

I just was not sure. The rule book is all bassed of 1/4 times.



Thanks

 

Ever think because they don't run 1/8 mile races?

 

NHRA or IHRA

 

Both

 

Pretty sure 25.1 is an unlimited cage.

 

Need clarification on 1/8 mile certifications.

1/4 mile 10 point cage and cert 8.49 and slower or 150 mph
faster and need a 25.1

so 1/8 mile 10 point good till 5.00 or 150 mph?

thanks

1/8 mile a 10-point cage is good to 5.50 sec or 125mph.

5.49 et and more than 125mph requires a 25.5 or 25.4 chassis.

 

10point only good too 125mph 1/8 ?

 

1/8 mile has a lower mph than 14/ mile speed limiter on a 10 point cage

Ineresting

 

Lot of debate about this . There are many cars in ultra street and even x275 that are 8.50 cert that are way faster than 5.49 . In my opinion its not the et that hurts you its the mph so no matter what a 150 mph is the same 1/8 or 1/4 if you crash

 

NHRA 8.50 1/4 is 5.35 1/8th . IHRA 8.50 1/4 is good for 0 yes 0 you can go faster in the 1/8 with a 8.50 cage than you can with a 25.1 god only knows why

 

Not sure where you found that info?

A 25.1 chassis is unlimited @ 2800lbs, and under.

 

Currenly 8.49 cage and would like to dabble in ultra street but not sure if I could legally run?

 

Still a few cars in ultra running a 8.50 cage

 

Never have understood why rule book doesn't have clearcut rules for 1/8 mile. With most tracks being that way now think it's time they write it down in stone. Probably don't want to piss people off with tech the way it is at lots of tracks.:smt102

 

One more page in the book would clear it all up.

 

Rules are
Roll Bar 10.99(6.99) or slower
Roll Cage 10.99(6.99)- 8.50(5.35)
25.5 Cage 8.50(5.35)- 7.50(4.50)
25.4(Over 3300lbs) 25.2(2800-3300lbs) 25.1(under 2800lbs) 7.50(4.50) or faster

 

Is roll bar 6pt and roll cage 10pt?
I have a 6pt that will be cut out and replaced but I run 10.7 and 6.8 now and should be lower 10s high 9s next season
Do I need a 10 point?

 

Yes
