Thank you Roman for all the hard work in making this forced induction kit available, safe, and reliable.

I can understand where a lot of the post can come off as questioning the supercharger kit from ESS, but I am sure that it is all in search off knowledge. Most of us just want to squeeze out every single pony from the N52. Again, with past companies struggling with this platform, its great that ESS has released something worthy to put their name on!! I just wish my local distributer had some heads up about this kit, especially since there are tons of modified bmws where I live that would be interested in a introductory group pricing.

If we add the supercharger that adds 80hp and then the active headers that claim 20hp gain, that totals to 100hp.

From my understanding, it seems that ESS is stating that they do not feel that 100hp is good for the n52 in terms of reliability and safety.

The above is what I am trying to figure out.

Roman, what's the bump in torque?

a 20hp increase from headers is quite a bit different in terms of engine stress than a 20hp increase from adding more boost.

And let's not forget Roman said +80 Whp. That's a lot different than 80 crank horsepower. That's about what I expected. Plus, if you have mods, you'll be close to the dynograph they posted a while back. St|g might even surpass it.

That's pretty exciting. Any word if the GM auto gearbox can handle this?

Won't ever know. I don't do FI.

Still even 230 stock hp + 60 whp + exhaust and headers will yield pretty nice results

He would never do FI, especially on his 128i.

Edit: I should have read the thread, but I told you so.

Hypothetically speaking

[JDane07]

Someone buy it for me and I'll test your exhaust and headers claim

If someone is local to the SoCal area, we would be happy to provide installation at no charge, with before/after dynos and share first-hand results with the forum.

Looks like ill be looking for a job in Socal for this summer

[StealYourFace]

I'd still love to know if the blower would screw up the disa on a 330i, or if the staged intake of a 330i would be an obstruction making it better to replace with a 328i manifold.

I think the stage 2 with catless headers and a shorter ratio lsd like I already have will make these cars rock. Can't wait to see some reviews.

My car is holding up very well and I plan on keeping it for a long time, but I would also be looking to refresh some items in the motor if I were to go this direction. I wish I would've looked into seeing if the high volume water pump from the 335is/1m would fit before I did my preventative water pump earlier this year.

Dang that's a great deal right there. I would jump on that opportunity if I had $4500 laying around.

[houbmw]

Roughly, about how much would the install cost?

We have revised our stage 1 kit that we have just started installing in house. Pre-order kits are shipping this week and retail sales will begin in about 2 weeks.

Changes have been made on the first release kit. The changes include slightly less boost and lower retail pricing. First the stage 1 kit will make gains over stock of about 60 whp. The new stage 1 will produce 5 psi and will use stock fuel injectors. Retail pricing will be $4,495.

We will later release a stage 1+ that will run about 6-7 psi, use upgraded injectors and make around +80 whp over stock. The retail on the stage 1 + will be around $4,995 and stage 1 customers will have the option to upgrade which will be very easy to do.

Roman, can you clear up again if the initial kit is for 330i/325i only? if so 60hp/80hp+ on top of 255hp is actually very nice, should have no complain about that.

also whats the progress on 328i N51/N52?

Note, I don't know that much about cars except what I read on the internet. I've never cracked open an engine before. That said, I do read a lot, so here goes some idle speculation:

Why would HP from headers be "different" from HP from boost, in terms of its effect on engine reliability? From what I understand, modifications to headers and intake manifolds increase the intake air charge through harmonic resonance. Forced induction is self-explanatory. At the end of the day, more air is more air, to which fuel is injected and the combination is burned to produce power. HP for HP, wouldn't the resultant forces on engine components be the same?

My guess is that the N52 as a whole system just isn't over-engineered with much further power potential available. It was built to be light and efficient (for its time), e.g. the all-aluminium block with no cylinder liners (only AluSil coatings). Once the design limits are known to the engineers, everything else can be downsized to save weight and improve efficiency even further. Challenge the limits with after-market tuning and things will break.

It's similar to N54 vs N55 -- the older engine was slightly more over-built and thus had more untapped potential that could be exploited by the tuning crowd.

From a big picture perspective, this is likely the consequence of modern Finite Element Analysis (FEA) design techniques, strategic product management and the never-ending pursuit of higher efficiency. These allow engineers to easily build machinery that has "just enough" strength (i.e. material) in the right places to meet their durability vs specific consumption & power goals. In the old days, you would go through multiple expensive cycles of build/test/strengthen that were more art than science, and end up with "unnecessarily" strong parts with "excessive" safety/durability margins (from a product management perspective). No longer.

Gains are on top of what the car makes stock. 25/28/30 are all being released at once.
