I concur. Anyone can up boost and run race gas and make power. Time will tell if this is a reliable tune.

I really need to get mine on a dyno...just put the V1.22 in my jb3 and ran map 6 for a 15 min test drive...WOW...

[fmxomar]

you guys have some big nuts to run 18 psi on stock turbos

[135i_TT]

Sweeeet

[Upgrade+]

I would prob only use that map on a track day and probably only do 3 runs lol!

Not hotrod ran that time with just the regular race map 7.

Screw the turbos I want to know how strong this motor is. Besides we won't know the limits until somebody pushes it. +1 to BMS, let the tuners do what we pay them for.

i wonder how its possible that he hasn't replaced his turbos yet. people getting failures with JB3, but he's running a custom map at like 3.5 psi more than the JB3 with 434whp, but his turbos have never blown? that's crazy if that's true.

because more than likely, the turbos will go first. so that will need to be replaced first. who knows if you can reach enough power to blow the motor on the stock turbos.

That would screw up the whole business

true - its gotta get pricey though, if he's getting the parts from bmw. but you probably don't have to do that.

Strong car for little mods.

Based on the graph, the car is producing over 400 ft-lbs of torque at the wheels from 2700-5600 rpm. That's really impressive. I wonder how much turbo lag there is.

And why would there be turbo lag? It's still using the same turbos.

Exactly thats why there are upgrades being made, and also how are we to know the limits. A couple months back we were thinking theres no more power above 15psi and the snails can't push it, but we will never know till someone does push the envelope.

I have only read about 1 turbo failure with the n54 and it was due to the person installing his intake and let something fall into the turbo inlet pipe. Where have you read turbo failures with the jb3? I would like to read that myself.

there is a thread entitled "turbo whine" here in the 135i engine/performance section about it.

I suppose that's one way to look at it.

But if you were more informed, you would see that over on his own site, he has already publicly posted that he has recently purchased a spare set of turbos.

He is not trying to hide anything.

He appears to be performing R&D to determine where the failure points are so that his customer maps stay below those thresholds.

Part of any reasonable and responsible R&D program.

If anything it's good for business when customers know that their tuner has tested the limits and is selling a product that does not exceed them.

honestly i dont know why this car shouldnt be able to push 18 psi. In my 1.8t vw you would spike at 22 got down to 18 or so and slowly move down to 14 at redline. I ran my car like this for 5 years and drove the hell out of it with no problems. These turbos are comparable in size and are working just about as hard. Unless these are a lower quality turbo you should be able to run a JB3 map6 as much as you want.... Just my 2cents :thumbup:

yeah, but these turbos are attached to a completely different (and larger) motor. not to mention its a twin turbo motor, not a single turbo. apples to oranges....or even further....bananas....
