.84 A/R

I'm looking into getting a new turbo with a .84 A/R for quick spooling & efficiency at lower RPM's. I don't plan on doing any towing for a good while & the bed doesn't usually have too much weight in it at any given time, so I don't feel surge will be a problem. Any suggestions? I've found only two with a .84 A/R, a stock turbo and the Turbo Thruster.

I figured. I looked and looked, but thought maybe I didn't look hard enough. Thank you for getting back to me though.

Your STOCK turbo has a .84 housing... and they suck nuts. They run out of steam at the mid-high end. Why would you replace your current .84 turbo with another .84 turbo?

If you are wanting better turbo operation, grab yourself a 1.0 housing. It will help greatly with mid-top end power and lower drive pressures.

^ whs. Go to a 1.0 if housing or even a van turbo with a 1.5. Mine doesn't drop off on the top end like it used to.

I'd advise against the 1.15 unless you have a lot of fuel pushing it or else your gonna have some ugly lag

Same thing I told you else where... You do NOT want a .84 housing on an upgraded turbo. Not sure what your thinking it will do for you, but a 38R with a 1.00 exhaust housing will spool faster then your stock turbo, with less drive pressure and lower boost numbers... All while making more HP and lower EGT's.

I know you think you know better then what everyone is telling you, but I have run well over 15 different turbo set ups on this truck...

01 F-250 SC PSD,320k,16 Isspro Gauges, AFE-2,CCV Mod,IAH delete,map reg,Modded H2e, 6.0 IC, 230/100 from P.I.S, Studs, 910 springs, Forged rods, Water injection,Hydra chip-No Limit/Gearhead tuning, Swamps HVHF IDM, MBRP 4" dual's, Aero, 6" tip's, 4" Revtek lift, 37/12.5/16.5 MT's

I didn't claim to know better than anyone on here in any one of my posts. I asked a question, & I'm getting responses. I appreciate everyone's time that they've taken to address this. Especially yours, as you've had over 15 turbo set ups. You spent the money, I have access to the info you've gained. I very much appreciate your input as well as everyone else who had relative info to share.
