DYNO: Catless + Intake + PROcede V3 vs. Dinan Stage 2 + exhaust vs. Stock

Stock 335xi vs. my 335xi (completely catless, dual cone intakes, procede v3).
The difference? Oh.. just 100whp

One thing to note: I thought the fan situation would be better (one good fan for the IC, and one fan for the Intakes).. but that wasn't the case. There was only one fan (albeit a better fan than last time) but still only one fan pointed at the IC... nothing hitting the intakes. Again, the same type of thing happened as last time... you can't hear the intakes at all. I'm very curious to see how much more power it would put down with a proper fan hitting the intakes... oh well another time.

Ok until I go back and get the .drf file (i only exported the data from the stock vs my run, i didn't take the actual drf. files) I can give only uncorrected numbers and the various conditions.

These numbers are UNCORRECTED, 93 octane, all from the same dyno (different days):

STOCK 335xi - 65° - 40% humidity - 264whp | 278wtq
Dinan Stage 2 + Exhaust 335xi - ~80° - Unknown humidity - 315whp | 344wtq
Catless + Dual Cone + PROcede v3 335xi - 83° - 50% humidity - 364whp | 369wtq


Take note of the delta (the thing that matters) Vs. stock with this combo of mods I've picked up around 100whp / 90wtq over stock numbers on the same dyno. I am a happy camper

Good numbers JP, hopefully you can get those run files soon and put the STD correction on them. When I compare my recent runs uncorrected to STD correction the STD correction is 7-8rwhp higher and 8-10retrq higher....

If this is not your actual stock numbers then you cant really tell the accuracy of your gains
i wouldnt really claim 100whp gain until i have a stock dyno of my car

I would safely claim 90-100whp over stock. The difference isn't going to be that much between two stock 335xi's on the same dyno. Plus, these numbers are uncorrected. Corrected, my runs from today would be better and the cooler runs would be worse... (somone correct me if im wrong.. STD corrects to 77° and 30% humidity.. among other things?)

I'm starting to consider going with this after seeing these type of numbers.

Very good numbers. I have the Vishnu exhaust, but how well would this perform with just that, and not downpipes I wonder.

Dynos on the 335i should be done in 4th gear. And yes it does matter what gear you dyno in.

Great numbers. Take your car to the track! I bet youd be running some great numbers with that AWD.

You want as close to a 1 to 1 ratio as possible.
