Hello Board.
I am a new member and the proud owner of a new to me 2011 335d. I love my new car and am doing a full alphabet delete in the next couple of weeks in order to try to make it a more reliable and longer lasting vehicle. The performance gains will be fun as well. I will be installing an Aquamist HFS-4 meth system at the time of delete and wondered if any of you have insight into the nozzle sizes I should get? The car is going to be dyno tuned after the delete and meth install. I want to clean my engine and get performance gains with the meth/water.
Thanks for any guidance.

How much performance gain from water/meth are you looking for? and what % mixture are we talking?

I am new to this and don't really know how much power I can make safely with meth. It seems like most people are running a 50% mix. I want power and longevity.
Thanks

750 cc's with a couple nozzles works nice, isn't too extreme and it helps it pick up about 20 hp at the wheels while keeping the egts down with 50%

I'm a dealer for Aquamist and have the hsf4 system installed on my 335D. I'm running a 1.2mm jet in the upper intercooler pipe, and a .6mm jet pre turbo. Total injected amount is about 695cc calculated at 35psi boost. I run 50/50 water and denatured alcohol (50% methanol, 50% ethanol). On the 335D, the system needs some wiring changes and modifications that don't follow the manual. It took a hot minute to figure out how the control box needed to be configured to properly interpret the injector duty cycle, but the war was won in the end.

I'm going to say the gains are well over 20hp by the highly calibrated ass dyno . With the w/m off, the pilot sports won't spin on dry pavement in a 2nd gear roll. With w/m on, the car will go sideways at will in 2nd on dry pavement and will break the tires loose easily in 3rd if it's damp out.

Well my 20hp 'estimate' is Dyno proven. My set up made 20 hp more at the wheels. Every set up will be a touch different.

Something isn't right if you are only getting 20HP out of 325cc/min of methanol. Should be more closer to 30HP. Is the flow confirmed or just the sum of the nozzle ratings?

Just sum of nozzle ratings.

how much do you charge for such a installation?

Who's tune are you planning on buying? I live in Richmond and will have my completed alphabet delete 2009 back later this week.

Hey, was that your car I saw sitting on the dyno this afternoon @ BPC??

Sorry I just remembered I had about a 40/60 meth/water mixture when I Dyno tested.

[CvilleBill]

Thanks Heather!
I'm getting my car done at BPC. Waiting on the pipe.
Heather, what meth system do you have?
Can anyone tell me anything about porting the wastegate?

[CvilleBill]

Thanks Bob. I sent you a PM.
