E92Fan from the UK section of this forum has extensively driven his car with fully upgraded turbos (compressor AND turbine wheel) on the Nürburgring. No problem for the engine or the transmission (his is an automatic), except that a baffled oil sump and better internals (pistons, rods) are recommended.

These are really nice numbers but something has to give sooner or later as you keep putting HP in. What is the first to go usually?

Engines arent rated by boost.. You could run the stockers or ours to 25psi and wont phase the motor 1 bit.. however put a 62mm billet turbo on there assuming you have the fuel to support it and you may kiss it goodbye..

I think it would be better said, actual power vs boost varies between turbo size, what you want to look for when rating how much an engine can take, its better to rate how much HP it can make. Although its a gray area with any engine.

On my last car their were guys that made 600WHP stock motor, and other guys that said dont go past 400WHP stock motor.

The tune is partial, as well as the way its driven. There is a bit of luck too.

Its actually TQ that kills the motor not HP so it varies on turbo choices.. If you make Monster Peak TQ early it will pull the rod bolts out in many cases.. We have killed motors with 500hp / 500tq that held 625hp on larger less peaky turbos.. Nobody truly knows the limit on these because of the fueling issues being the main problem.. If it wasnt direct injection the car would be far more advanced in the aftermarket world then it is..

there has been a few heated debates in the e36 world based on this principle.

gt35r vs gt40r

35r spools quicker and will deliver a lot more bottom end TQ but not as much high end HP. Been debated its harder on the rods.

40r spools slower has less TQ down low but can flow a ton more air up top for more HP. Less stress on rods.

I prefer the 35r on a street car w my 3.2l engine but certainly question if it harder on my stock rods.

I would agree 100% on all counts.

Which is why seeing some of these people with monster torque on nitrous, down low on the RPM makes me cringe.

For instance, I ran my last car on the dyno, in 90+ degree temps, with about that much humidity (90%). I didnt put any correction factors on WHP numbers.

After all its just a number. Do I know it makes more power in cold weather with less humidity, of course. But, I rather low ball the number anyway.

For your sake, I hope it works out for you and you enjoy them.

Hey, I HATE correction factors and am a BIG advocate against them.

But it was obvious that some people here didnt understand that 38* colder weather makes a big difference. So I wanted to put the numbers in corrected form so people could understand there was more then a 9whp gain.

I don't understand your last line? Are you talking about the AWD turbos or correction factors? I'm not buy the AWD turbo nor do I use correction factors...

My bad on the last line I thought I was quoting the guy who made 9WHP. Brain fart. Its all good.

Lol that would be me, but yeah i'm really enjoying these and even much more not that the weather is constantly above 50F. With the new 2-14 DIC Maps the car is a blast to drive, and at 17.5 psi I find it hard not to drive everywhere lol.

I despise down low torque. My old car was very sensative to blowing motors downlow. To me, its useless because when it matters you are under 4.5k for 1 gear, the rest is 4.5 and up, and thats where I want my power lol.

I heard of your old platform throwing rods if you WOT in a high gear at low RPMs.

Fuel starvation is 1 weak point - not designed for the demand....

What is the other weak point? Clutch? 450 to 500 BHP - what gives first?

I know what you mean about dropping off and these turbos seems to fit the bill nicely.... but I do use the gobs of torque all day and every day (that you wouldn't get in a M3) - pulling away from a light, passing... I guess I just use the car in it's sweet spot - which isn't high end and makes it such a nice DD.

This car pulling like it does at 4k to red line would be the best of both worlds....

What sort of cooling issues do you run into running above 18PSI? Does your test car have additional/upgraded oil cooler(s) or radiator upgrade to handle the additional heat?

[Overboost]

Hey Mike can you check your Inbox? I need a new clutch so I can dyno these turbos at a higher boost level. I'm running these at 17-17.5 psi currently and the clutch is definitely slipping.

Only on a track might you find those problems. (road course).

dyno'd yesterday. trying to figure out how to open/post .drf files on Mac
Full Bolt-Ons with AWD Turbos. PROceed V5 12-17 upped turbo maps.
All run was done back to back without any autotune to adjust. First 2 pulls, I have experienced weird fuel drop around 4000 rpm, and couldn't really finish the pull but once I reset(reupdated firmware,map and clear codes) everything on PROceed....are following
with 101 oct. on stock map I ran 298 rwhp @ 7psi no meth, on Map1 without letting autotune adjust I ran 350 rwhp @ 12psi no meth, and Map 2 without letting autotune adjust 420 rwhp @ 17psi no meth, same map2, again 420 rwhp @ 17psi. Will post dyno soon
Numbers arent the great but once I add some proper meth setup (Shiv!!!) + newer maps and up the boost to 19~20psi I should be at where I want to be at 480/480.

You wont hit 480/480 with this turbo. 17psi full bolt ons on race gas and only 420 sounds pretty low, post the curve up when you get a chance.

Still trying to find out how to post drf files haha

edit: I think 480/480 very much doable with proper meth kit, and also with newer maps. only time will tell

Install WinPEP on Windows through Parallels, that's what I did...then in WinPEP you go File->Export Data and you can export as JPEG

Update to the new 2-14 maps and re dyno. I was told the dyno dynamics I dyno'd on reads 13-14% lower than the dyno jets in town which puts my 361hp to 407-412hp at 15psi on the 1-24 maps and 2-14 DIC maps feel better still.

Thats great power with no meth at that boost level considering how they hold boost well past the stockers.. Keep us informed as the results come in.. I appreciate all the feedback on the REAL WORLD results as well..
