Default Super gas hood rule

Hi
Just working on a super gas car which is getting a enderle stack injection so stacks will be sticking through the hood.
Car will have a hood just no scoop over the stacks is that fine in super gas ?
Or is there a rule stating otherwise ?
Thanks

Check with a tech. There is a reference to an 11 inch rule for hood scoops on SS and SG, but no stated exemption for stack injecters. If a carb has to be covered then injectors might also.

Only carbs sticking thru the hood need a flash shield to prevent fuel from siphoning out .
Stack fuel injection is ok without a scoop or flash shield ,as there is no fuel bowl or vent for fuel to siphon out of .
I would defiantly run screens in the stacks . hard enough to keep debris out of a carb let alone 8 stacks !

the down side of mechanical injection is that for it to make it work consistently on a throttle stop usually requires closing down to Idle.
Some racers have had some success using a part throttle bypass off the barrel valve [similar to what a Sprint car or old Modified Stock car would have used ]. by using a controlled bypass on the barrel valve I've known a few racers who successfully got the injection to cruise on the stop at around 4000 rpm. But most guys opt for going to idle as it yields much higher MPH .
Kinsler used to offer a nice slip in domed screen that had a formed ring that secured in the stack tube. ...not sure if they still have them.

I will look into both and see what I can figure out with it.
Wanted to run it for the nostalgia look which I like, but if it had to many disadvantages in a .90 class car I didn't want to be fighting myself against consistency either.
Thanks again

If you have it, try it. Launch and go back to idle as quickly as possible. Only have enough time WOT to get a good reaction time.

My S/C car has Ron's Terminator mechanical injection, and I think it repeats very well.
