[QUOTE="tt335ci03cobra, post: 12726382, member: 68944"] Ya that makes a lot of sense but also every turbo is different. Lots of variables. I'm going from off the shelf non blanketed/ non bb hpp units through 2.5" downs, not sure the origin or real manufacturer, to blanketed triple ball bearing oil-less units with 14 vein and 3" downs. The 14 vein is designed long fin to reduce thermal and gas bleed off. I think it'll be more like 4.5-5hp and 22.5-25hp per mm because of inefficiency vs efficiency. Ive seen a few hellion single 76 cars gain 150whp from going to a real effiient single 80, the maths there would be 5-6hp and 25-30hp per mm comparatively. Anyways, if I can gain even 4hp and 20hp per mm, that alone should put me around 1000whp on 20psi with out even factoring the down piping. I'm thinking 4.5-5hp and 22.5-25hp because of the step up in downpipe size coupled with the turbos. Also that's only up to 20psi so far, where I made 915, these turbos will be more responsive past 21+psi offering more power since the 48's are being replaced by 62's, leaving tons of top end. I may only gain 70-100whp on 20psi, but running 21-25psi should gain more power still I'd think. I don't think these will be maxed out at anything short of 25psi but 28psi might not offer much more than 25psi. I'm hoping 25-28psi on meth makes 1100whp, here's an older graph of 885whp on 20psi before boost-a-spark, fuel pump regulator, new ba3000 maf, and some minor tuning updates. The low torque down low was because we couldn't floor the car off the get go otherwise it would blow the tires up at ~50-70mph on the dyno so my tuner was rolling in an going full throttle around 85-90mph. [IMG]http://img.tapatalk.com/d/13/02/11/e5e9eme5.jpg[/IMG] It looks like there's tons of potential left powerband wise, and I hoping if it does make 1100 that its atleast from 5500-6500, I don't think it'll be from 4800~ like it makes power now, but even with my 3.08 rear, a 6500rpm shift doesn't put me too far off 5500, maybe I'll start pulling 6750-7k shifts if power really moves up the graph. I'm thinking it won't though, and if anything it'll fully spool quicker than it does now because everything I'm seeing on comp turbos is all about ridiculously quick spooling. I know they have a turbo in the fastest single turbo terminator (7.75~@180) and when I watch the vid of it, it seemed to spool really fast for a single 88!! Anyways, I appreciate the honest feedback and it keeps me humble expectation wise, I want to run as small a turbo as possible for my goals so I'm hoping these just barely do it so I can have the most streetable powerband I can get sense I don't have a high rev setup yet.
