Thats what I thought when I looked at it. Talk about a huge turbo this thing is big but the exhaust wheel is small. On the C-12 Cats cranked up to 425hp on the 7-tons the Marine corp uses this thing has some lag to it. Even staright piped the things still laggy. My buddy is looking into making a compound setup on his mech. 5.9 hes droping into his old f-350. What do you think about using this as the big turbo and what would be a good one to use as the small turbo?
A smaller housing will make a big difference in lag. Its really not that big of charger with a 68mm inducer and 74mm exhaust wheel. To put it into comparison a modded h2e is generaly a 66mm inducer.
Yes the 1.44 housing is going to be a bit large but Im sure you could probably get a smaller one, maybe even with a t4 flange. It would probably be ok as the high pressure charger.
You looking to put this on a cummins or powerstroke? If its a cummins then depending on what you want it may be a bit large to be driven on the street in a compound setup, but then again Ive never messed with a cummins that much.
I'd think it'd make a very responsive primary and a very laggy secondary. unless he tows alot, i'd think a bigger primary would be in order. I base these estimates on the displacement and the compressor inducer.
Well is it going to be a street driven truck or used for only competition? If its going to see street time I would have to say it may be a bit big for the secondary charger. Others that have messed with a cummins might know a little more, thats just my oppinion.
Nope street only. Keep in mind that it is getting a 13 double over in it. Thats a 13 speed tranny out of an old 198? KW. Towing some yes. Not in it for the speed just for the reliability and having the ability to tow without EGT problems.
depends on his goals IMO. for street, that's too big for a Secondary. if he's not looking for huge hp, that may do well as a primary for him. if he's looking for 600-700+, i'd expect it to start becoming restrictive.
again, this is completely based on displacement Vs inducer.
Nothing in the 6-700hp range lower then that much. I would say 4-500 HP max
