velocity stacks
dlong70elcamino:
Hey Cliff hope all is well with you. Been hearing some chatter bout running velocity stacks on 4 bbl carbs adding hp what are your thoughts on it and have done any dyno testing with them. Thanks Dan...........
Cliff Ruggles:
Might work OK if you have a big hole in the hood to accommodate one.....
dlong70elcamino:
Bought one that is 4 1/4" tall i,m gonna try it at the track at the Dragway 42 Rock&Race this weekend see if it runs any better. Clears my hood by 2"tried to send ya a pic but said file was too big.Have you had your car to the track this season? so far this season I got the Camino down to a 13.09@103 mph trying to get that 12 sec pass it,s tough lol
von:
Better air density the next few days should help by itself. You really need to do an A-B-A test to see if the velocity stack helps or not.
Cliff Ruggles:
Every 1000' decrease in DA will be about a tenth improvement in ET, provided traction is good.
Make sure you are filtering the incoming air, would hate to see a tiny stone get sucked into the engine during the testing.......Cliff
