Fair enough, if you want to keep the original HPFP it's 1500$ + the cost of a second HPFP which you obviously need to buy, which comes to just under 2300$ on your own website. Regardless, it's kind of a moot point to argue about prices until these products are actually released. Carry on.

This is the BMW community and I can totally see people doing this. :(

So it's going to basically follow the footsteps of the S55 sharing parts with the N55. If thats the case, whats the point of BMW continuing to water down the "M-Factory" parts into regular 3-series. Every M car past the E92 after the F10 M5, including the F80 M3 has officially lost the way if this is the case. F80s and F10s are no longer considerably valuable in terms of future-classic potential and will just deprecate into the hands of kid-racer tuners tbh

Why would you put on an old one? Um, because there is nothing wrong with it? I have not swapped a HPFP on any of our shop cars for the better part of 4 years. So to follow the logic here. You buy new rims, your current tires are in great shape, a perfect fit, and are inline with your current tire needs. But you throw them away, and buy new tires (because why would you put on old ones). Replacing parts that are in good working order makes zero sense. So yes the Shotgun is $1500 with a contoller, not to mention nothing on the market will compare to a double barrel flow wise thats even in the same league price wise. We wont even talk about nothing is tested, or proven in the slighest except the shotgun. Carry on

S65 stock motor's curve pulls to redline but the top-end seems to lack efficient pull/power compared to a modded TT N54. The torque from a modded turbo N54 seems to give it the advantage in top end racing so would a Twin turbo setup on a V8 S65 motor give it insanely more top-end power? 650 wheel torque from a S65 really is fucking impressive and almost shits on their own Gintani superchargers/ESS kits. The questions is the cost of it and whether its worth it but god fucking damn this is good

So is N55 officially coming out the trenches of tuners?

LSD surely helps with "inside wheelspin" flooring it out of a bit of corner, think that's what he means... I have an OS Giken Superlock, it's a massive difference compared to an open diff.

Lets also not forget that the Shotgun will not work on xdrive cars. So there are other limitations. On top of the fact that if you live in California you want your car to look as stock as possible. I am sure the shotgun would probably not be noticed as a modification. however, i like the stock look of this set up and the Porsche pump has prices all over the place. I have seen 350-2100. i am sure there are junk Chinese rebuilt units.. Be interesting to know how much a reliable one will cost.

I would'nt call ditching magnesium cost cutting necessarily. Whenever bmw uses magnesium it almost never holds up. Look at the M60/m62 valve covers, they disintegrate before your eyes. The S55 requires the use of rubber screws to help prevent the pan from corroding from being bolted by aluminum. Its not worth the ~2lb weight savings bmw claims. The s58 does look promising though, it seems like they're not taking too many chances with mechanical design just wish the main bearing caps had more than two bolts but im sure it'll be fine.
