Holbrook.... 7.64@182
 

Hey guys, I'm here at NMCA Allstar Nationals in Martin, MI. Chris Holbrook just went a 7.64@182 in the Super Car Showdown. It is an impressive run in itself, but it was 4100 feet with a Bar of 28.88 and water grains were 120 when he made the run.

WOW!!!

Re: Holbrook.... 7.64@182
 

Pretty impressive, what rear gear do those cars run and tire size?

Re: Holbrook.... 7.64@182
 

This was the funnest class to watch in NHRA....WAS. Good thing. NCMA is around to keep this class going.

Re: Holbrook.... 7.64@182
 

Holy smokes that is riding, unreal in that air!

Re: Holbrook.... 7.64@182
 

I remember when Top Fuel ran 7.60's. LOL! Nice pass.

Re: Holbrook.... 7.64@182

Drew Skillman.......7.62

Re: Holbrook.... 7.64@182
 

I understand these guys had to make a bunch a changes but it still suprises me that the ford group were complaining about the new rules for parity. There has not been much drop off since the nhra rule changes were made. Anyone know how competitive it is between brands at NMCA? I haven't paid much attention to the races as I have in the past.

Re: Holbrook.... 7.64@182
 

Make that 7.56 @ 184.

Re: Holbrook.... 7.64@182
 

I watched that run, it was awesome.

Re: Holbrook.... 7.64@182
 

All I can say is wow!!!

Re: Holbrook.... 7.64@182
 

Definitely won't see that at an NHRA event. Nhra loses.

Chris Holbrook/Skillman 1, NHRA 0

Re: Holbrook.... 7.64@182
 

what chassis cert do those cars have. Are they only 7.50. if so getting close

Re: Holbrook.... 7.64@182
 

How quick and fast will this class achieve with a big tire?

Re: Holbrook.... 7.64@182
 

7.20's with 14×32's by my calculations

Re: Holbrook.... 7.64@182
 

Did you factor in added road load from the Big tire?

Re: Holbrook.... 7.64@182
 

Yes, calculates at 182mph

Re: Holbrook.... 7.64@182
 

2 tenths improvement in 60ft alone

Re: Holbrook.... 7.64@182
 

I'm guessing their cars are 60fting at 1.teens, so I doubt a 2 tenths improvement in a big tire.

Re: Holbrook.... 7.64@182
 

It would be nice if someone could post a time slip.


Just a guess of what happened.


60 Foot ET = 1.2263
330 Foot ET = 3.2222
1/8 Mile ET = 4.8948
1/8 Mile MPH = 147.2026
1000 Foot ET = 6.3385
1/4 Mile ET = 7.5645
1/4 Mile MPH = 184.0163

Stan,

The Blue Font data is from the actual time slip.

Re: Holbrook.... 7.64@182
 

so what 2021 challenger dragpak is going to get the letter from NHRA that your car is only certified to go 7.50, no faster. just read the article about the car and says it has a 7.50 cert cage. also have to meet all of the other rules for 7.50, I think they are upgraded license, fire suppression, clothing SFI 3.2A15 and hans device. could be interesting loosing car could protest. and i have seen that done at a bigmoney bracket race

Re: Holbrook.... 7.64@182
 

It is all about traction. I believe these car have run 60' times in the teens. This car does that (a low 1.17x) and it will run under 7.500.
