hood and e.t lose

Got a crack in my 6 pack hood and want to do some more racing this year,what loss in e.t. do you think I would see running with out a hood? Car is a 10.50 car

Probably won't slow down at all, maybe have more mph. 6 pack hood on my car pulls a lot of air in the 1/4 mile, tries to pick the hood up by the scoop. I finally put a dzus button in the center of the hood to a bracket to keep it from coming up. I don't have a problem with it when I run 1/8 mile class. If you run a good air cleaner you'll be fine.

It is possible it could affect how the car handles. No time to do a fiberglass fix?

Might need to jet a bit leaner. But it all depends how close the jetting was to the fresh air set-up and how well it worked originally. (i.e.: turbulence, seal, etc.) Make sure the top of the carb isn't too close to the bottom of the new hood.

It may actually be more consistent. Underhood air is more consistent and a good bracket racer I know actually blocked of his '68 Cuda Hemi-style scoop with clear lexan or plexiglass.

My old car didn't show any loss when I put my 6 pack hood from pro stock scoop

I won't be running a hood at all

HI Eddie, hope you are well.I lost no et at all but the hood wasn't sealed, if i were you i'd definitely run a decent filter.
