I was wondering if a guy could use a throttled intake on the 4BT? my dad has a exhaust break on his and it sucks!!!, it pretty much dont slow it down! it is a 4" jacobs unit. I plan on just using a ball valve type valve in the intakes system between the turbo and the intake I understand I cant totaly shut the air off it might hurt the engine but it seems to slow the engine down way better then the exhaust brake does especially at lowers rpms and speeds where my Jeep will need it the most for compression breaking< as a side note isnt the new 6.7Liter cummins setup like this?
