can u run at NHRA dragstrip without a hood on a test and tune day

you should be able to.. just call someone at the drap strip before you go down..

if you have a mechanical fan you will not pass tech, electric fan- and you should be okay

I think some tracks also require you have an air cleaner as well if you don't have a hood?

its legal at my track.. some random guy at the topend

It may be a track discretion. Typically there's no problems running without a hood but some tracks may say 11.50 and slower cars must have a hood. I don't have a current NHRA rulebook handy.

I'm almost tempted to ditch the hood just to save some weight. Third gen hoods are heavy even the fiberglass ones and I have a cowl and aeroscoop mounted on it.

my hood can't weigh more than 10 pounds total stephen....must be a bolt on hood ?? mine is as flimsy as they come and super light.

The bolt on hood is a lot heavier then the lift off one?

Lift off should be the lightest since bolt on ones go on like a stock hood.

My harwood 3 inch bolt on cowl hood was 42 #`s and the new 4.5 inch glastek pin on hood is 17#

pin on hoods get to be a pain in the *** sometimes. on tnt days i just take it off and run without it. it looks trashy but i dont mind.
also, for some crazy reason every time i take it off the car runs faster. lmao!

less weight, more air getting to the filter, cooler engine temps..

Because my fuel cell is at the front, I have to open my hood after every run just to fuel up. A lift off hood without a helper could be a pain. If I had a pit crew, having a very lightweight lift off hood would be the way to go.

I was considering fabricating a lift off hood from some sheet aluminum I had access to years ago. I couldn't get a sheet big enough to do it as one piece. I figured just weld 2 pieces together down the center. Now with the cowl on my hood, it would have easily covered up the welds.

yup, thats the problem. the car needs a 2 man crew to operate with the lift off hood. im trying to come up with an aluminum hinge for mine. its just not fun having to get somebody to help with the friggin hood after each pass.

i'm always at the track with at least one other buddy who either rode with me or has his car parked next to mine, it's never an issue, even for a stranger just walking by to just ask them to help me grab the hood real quick.

could always cut some kind of hatch/cover to fill the cell through without lifting the hood...

That would look horible. I have a lift off hood. It can be alittle more of a pain sometimes but it makes working on the motor so much easier when you dont have to wory about ducking around a hood.
