Carb Hat VS carb box on blow thru
 

Anybody running a carb hat instead of the box ? anybody compaired the two ?

My buddy is now running a hat. He was running the box before. I am pretty sure he gained some power, and the hat is much easier access for tuning carb. His throttle shafts are oringed so fuel doesn't escape and leak. I think he got his hat from steve morris.

who's carb did he use ? not all o-ringed I don't think...

C&S . He switched from prosystems. He's Extremely happy with the C&S now.

thanks..I ran a prosystems one for 2 years, but he only wanted me to run in the pain in a ass box...

Rob,

You have a .pdf file in your email. It should provide data on this very question. It was to large a file to post on OSO, sorry.

Bob, thanks...that was pretty interesting..not what you would think..Rob

The hat is not uscg approved and neither is the oring or pressure fed sealed throttle shafts..if you have a fire on board and the carb is not in a box then the ins will deny the claim..

i have a friend that used a box first then used a hat,,really did not see any power increase..he did see more lower end power when i told him to get a more aggressive throttle linkage rod so the secondaries opened sooner..

Is there any chance you could email me a copy of the pdf file ? I tried sending you a pm but your box is full..

Thanks for your time,
Scott C.
