BMW 135i Stg-1 dyno compare
 
1 Attachment(s)
Finally got to put my 135i on the dyno and see how the new stg 1 tune is doing. Did a couple of pulls and had trouble with it spinning on the dyno, but did get a pretty good pull on the second run. We then put the car back to stock and got a comparison from stock.

Pretty happy with the results, 321whp and 377wtrq, around 378 bhp with 15% drive train loss.

Here is the picture:

I will get my new Hankook sticky tires on the back and put my data logger on the car and give that a test. I just spin now, its freezing cold and the roads do not have much traction.

Will test it out soon and let you know,

N54 or N55? Is it Dinan or BMW stage 1?

Ah, n54 and jzw software.

Yes, you have it correct sir.

I like the N55 too, back to the single turbo.

Once I move up to the DP and IC, then I am debating on how to increase turbo flow. My turbo guy can do the larger turbo wheels for me, maybe clip the turbine side a little, but there seems to be some dis-like for this compressor wheel upgrade.

I have been updating the tdo04-15T turbos for years with the larger 19T wheel and I love how those run.

The advantage would be cost, upgrade the stock Tdo3 turbos for 450 each and make another 50-60bhp, bolt right up, no new parts needed, cost is very low.

Second option is to go to something like the GT 28RS Disco Potato and make a lot more power, cost 1100 each and then manifold and dp mods to make it all work, oil and coolant lines, etc.

I may play with the Tdo3 compressor wheel upgrades first and see how they do, how much more power and how high the egts are and see how they hold up.
