Power/torque curves look great. Looks like your efforts are paying off big time and some people have their foot in their mouths right now.

In other news...

Made some fine adjustments to the n52 turbo car today, broke the 500hp zone..... STILL ON THE STOCK FUEL PUMP LOL

I see that your DME is an MSV70. I installed my supercharger into my 07 328i and it has an MSV80. i'm curious what the difference is between the two DMEs and is there a tunability issue with the 80? what are you using to tune if I may ask. would BPC be willing to remote tune my car for smaller pulleys on the s/c?

We watched this build for some time, only to be told that there are reasons why this may not hit production. The manifold design takes the a/c out of the equation and there was talk that there may be a manifold design changes, that would alter the whole kit. This was only meant for the e90 guys anyway. Although the power achieved showed the n52 potential, we may not see this in production.

Just this version of it or the project canned entirely?

From what I've been reading thruout, the kit that was built on the car will not be available as a kit. In the end, they listed numerous issues that presented themselves during build, which would be expected in my opinion. The most was a/c removal with the manifold built, then 4th gear let go. Being that this kit was to be offered with a full hot kit,cold side, inner cooler,EFR BW turbo, and injectors, it was to be offered at a 7-8k kit. Then there was talk of of offering a partial hot for an off road kit, and building a different manifold to try to offer a kit. The last update was that they ended up turning the kit car into a race car.:(

Unfortunately the N52 turbo kit is on hold due to the fact that it would cost too much to produce and we feel the end consumer would not be in the range as far as pricing and how much of the vehicle engine bay would need to be reconfigured including the potential for having to remove the AC. We are also in the process of moving to a new building in the upcoming year and will have months worth of projects to finish both with other customer vehicles and the new shop itself. It is something that we would love to be able to crank out like clock work but it is just not in our ability at this current time. Others are currently working on N52 turbo kits and cars and we are here to help and have shown that the possibilities of the N52 are real !!

It was epic to watch something built that for years was said it was never possible to turbo a n52, even the 335 guys were all over this,lol. This surprised a lot of guys and proved of you want it bad enough to, it's possible. There is another op out there running the only street n52 car out there, the thing is an animal. Props to these guys for building projects that couldn't be done...or so they say:p

There making great power,like 516 hp@14 psi or so. It would have been well worth to turbo a n52, the head is a better design and flows a lot more. The lower end kinda keeps the power at a minimum,but doable.

I am Jack's complete lack of surprise.

Oh nice. ..so you are continuing as a drag car, and not producing a kit right?
