Potential power gains max
What could be predicted power gains WHP wise if we had a N52 with open tablet custom tune, on race fuel or cam2, disa stage 3 manifold or CRd intake manifold, euro box (so I can feed the Nitrous line.) super sprint catless headers down to super sprints first section that deletes the 2nd set of cats with a two e cut outs. Basically a straight pipe system with a click of a switch and then back to no cats with stock res and stock muffler with switch back off. And lastly if I added a 55-75hp wet shot. I want to break 128i history here since no one is brave enough to do it, or I'm just crazy but I don't stop at stock lol. I want a sleeper 128i that would creep on other mild bolted 135i's. Give or take I will reduce the weight of the car with some things here and there. I'm planning keeping this car and turning into a all track car in 2 or 3 years.

No haha I was asking about the open tablet that one time if tuning tables would make this all possible.

Kobe, I found some belgian guys tuning a bmw 128i to 260 HP...
http://www.asdchiptuning.be/be-nl/ca...102/index.html I think it's without the DISA. With disa they should be able to get it up to 270 right? May be worth a shot...

22RPD currently has a 328i with 22RPD intake trumpets and Catless around 270whp or 320hp NA with MILVs (extra 1mm lift intake)

Yeah, same 328i, here's his thread. https://www.e90post.com/forums/showthread.php?t=2063463
Lots of interesting N52 development going on right now. 22RPD stated in one of their videos that they think his headers (AA reps) have actually become a restriction again with the trumpet manifold. StageFP has N52 products in the works as well.

But they aren't making 270whp. Their dyno reads 8-10% higher than a dynojet. |

The 22RPD intake looks compelling, looking into it for my track car. Also looking into the N54 intake, but seems like it's not the easiest to fit and requires a bit of hackery to get a good intake fit as well as the hoses to the airbox. The 3 Stage seems the easiest but not the optimal for a track car. Anyone running either N54 or 3 Stage comment?

It will require a bit more work - but not too much. The 3 Stage is likely a little more expensive because the manifolds will need DISA valves in good shape (inspect and test before you install it) but it will make 95% of the N54 manifold plus more low/mid range power. It's great for a daily, but the N54 is going to be "better" if your just tacking it. |

Hey, wanted to add that yes the velocity stacks is an extra power mod. I’ve been beta testing them for a few weeks now. Very fun, loads of more usable torque, and more power at the top. (Edit: compared to N54 manifold w headers) Still not dynod yet but here’s a photo of mine.
N54 air duct + 3 inch hose from fog light K&N prefilter (not in photo) as temp air filter Vibrant hose to replace hardline vacuum line N54 catch can currently venting to atmosphere Fuel Vapor tapped into cylinder 4
