I'm looking for some kind of help (certifiable). ABSOLUTELY NO TO COMPOUNDS. (Thank You).
I have been still kind of on the fence on turbo selection. The truck is an 05 QCLB 4x4 auto with Firepunk comp stage 1, stock stall DPC. Engine will be fresh bored 20 over with Mahle open bowl pistons, stock rods w/ARP hardware, balanced with fluiddampner and main studs, Hamilton 178/208, 150% s&s wide spray injectors, stock and LMM ATS dual fuelers, stock head with o-rings held by ARP 2000, Hamilton springs/rods as well as a valve job, Stainless Diesel T-4 manifold, and will be dyno tuned with HP Tuners when I get to that. The guy that I normally deal with swears that the 467.7 is the best turbo for me, but I am debating the 369sxe (he's on the fence about the durability of small frame turbo at those kind of power levels, as am I), although I have heard that towin with the 67.7 can be a pain in the but sometimes and that the 369 makes amazing power down low.
My goal is 850ish HP but I would be happy with higher numbers as the truck isn't the daily driver that it used to be. The truck HAS to be able to haul my 5th wheel (~5000#) to the events that we like to attend (local, regional, and national pull events as well as camping and general fun weekends an occasional trip to Wyoming/Colorado), but I still want to be able to push it into the low 11's in the 1/4 mile when I decide to go, or embarrass the local muscle car guys (especially with the camper hooked up).
I'm really looking more to the 369 for it's good spooling characteristics. My biggest concern is the drive pressure of the .9 housing at these kind of pressure ratios.
Sorry to drag this subject through the mud again, because I know it comes up but I also know that the majority of the fuel setups that I see are lessor injectors.
TIA
