Evo 8 MR build - Power expectations
Hey guys I've decided to do a build and I would like to get a rough idea of what my car should be making with the following modifications
Engine
-kelford 272 with upgraded valve springs
- tomei cam gears
- Manley rods
- acl race big end bearings
- stock Evo 8 mr turbo 16g 10.5 hotside
- full 3" inch turboback exhaust
- ARP headstuds
- cometic head gasket
- lower intercooler pipe
- turbo is running on 24 psi
Fuel
- 1100cc injectors
- 460lph fuel pump
- e85
Car is still running stock intercooler with the exception of the upgraded licp, I am looking to upgrade the turbo in the future if so what will the car make with a upgraded turbo compared to what I will be making with standard turbo ? If anyone has a estimated answer on what power figure the car should make with the listed modifications I would appreciated it.
Thanks !

You'll be torque limited by the stock short block, and the 6 speed trans. On bigger turbo's, you can well into the 500's with torque held at 400ftlbs..

Forgive me for asking but why the post on EvoM rather than EvoOz? Yes there is a world of knowledge on here but would have thought you would get a slightly better response (ie point you in the direction of workshops, suppliers etc) on a local forum?
You won't make 400hp (on a local dyno) with an 8MR turbo, or a IX turbo. Looking at 260kw (~350hp) with the MR turbo. Maybe another 10-15kw with the IX turbo
300kw (400hp) is very achievable with GTPumps 712, FP Green, etc etc. Bigger cooler will be needed when you change turbo; Plazmaman & Hypertune do some nice tube & fin units (personally I'm against placing extra weight over the front wheels which is what a bar & plate cooler will do)

I'm not browsing any 'Dyno results' sections because its all irrelevant. Regardless of what you US guys make, on a local dyno (the OP is from Australia) there is no way it will spit out that number. I don't want a dyno debate, nor do I care what you US guys make, its simply not happening here nor will it ever happen here, /story.

Haha all good , I have heard that the stock Pistons can put out decent hp some thing like 500hp I might be wrong, I'll stick with them for now as I can't see myself pulling down the drivetrain to support those numbers I'm upgrading rods as they are known not to handle torque very well in excess of 400. I'm running e85, I'll have some fun with whatever power figure I can get out of the stock turbo then upgrade to something bigger in the future, one more thing to add I'll be adding Nippon npr rings to the stock Pistons just to be safe on the sealing side of things, I'm not looking for a build where I have to tear down the drivetrain to support my power.

Agree with everything fossilaus has said. You're looking at about 250ish kw atw (give or take), or about 340ish hp atw.
If you want closer to 300 kw atw (400hp) or more, then a GTP 712 / 762 / 822 will do the trick.
Get in touch with the vendors - or community - on EvoOz, they'll steer you in the right direction.

If he gets a 9 turbo there is no reason to not make 360-380hp on a mustang dyno, or around 420hp on a dyno jet.
The stock pistons are not forged. So, you still need to be careful about making sure you don't get detonation. Granted, you still don't want to push much more than 400ftlbs of torque through the 6 speed. So you should be fine.

My car made 420whp/400wtq dynojet with the current setup, except a 9 turbo instead of the FP red. On E85 of course. With the upgraded rods, you'll be able to get more torque out of it because the rods can handle it. And maybe a bit more power. Porting the turbine housing definitely won't hurt.
