No its SORN at the moment, I am using my girlfriends 130 for fun at the moment (Cupster's old car). Mine didn't pass emissions with the old tune using the MAF and old injectors so drove it until the MOT expired. It started and ran the other weekend. Going to fit the BOV controller and start it and check the BOV is working as it is meant to be then I'll fit the larger injectors and MAP sensor. I need to read the ECU and send the file to Bob at BPC so he can send me a base tune. BPC have now tuned a handful of cars with the ESS supercharger and have their own N52 turbo on stock internals and ECU so reckon they can get the tune 90% there without any data logging.

It'll never be a torque monster but should have a lot more top end power. BPC reckon from their work on the turbo N52 that 9 to 10psi should get between 450hp and 500hp (American dyno). Their turbo car is on 550hp with stock internals and ECU and same custom injectors I am fitting to my car. I will see how she goes with the current pulley which should be running around 7psi and then maybe drop the pulley size down. I've made sure all the tweaks to the intercooler etc will allow me to run much higher boost if I want.

Has anyone also read about MILVs? Modified Intake Lift Valvetronic supports? There are guys in the US adding an extra 1mm lift to the intake valves and getting some good NA gains (20hp or so I think) with NA Alpha N tunes from BPC. I think BPC are also fitting the same MILVs to N55/S55's. Maybe I will consider doing this in the future as it should have even bigger gains on the N52 with some boost and the parts are cheap...its the time to fit that puts me off at the moment.

The photos make the wheels look darker than they are but potentially a little dark for my tastes. Here they are on the old owners silver car. I will probably only run them in summer so will see how I feel about them when the sun is out and the car is clean. Love the design though, as I said they are incredibly light and well made whee, I think they used to be Sootys wheels that he had on his M135i, then sold to another M135i owner and now bought by me.

They were working last week which surprised me! Which photo host sites are people using now? Is Photobucket a complete no no now? I wondered if they'd reversed the subscription changes from a few months ago....

As THETYRANT said, imgur or tinypic (with account).

If you could post the photos again would be really good! :D

Ha not much to report, although the Vectra has had its first mod...the rear seat belt points were corroded so to pass the MOT I have ripped out all the rear seats and it is now essentially a Vectra van :). I can confirm that this mod does not improve the 0 to 60 time with a 1.8l 16v engine :)
Read all through this today. Your car is unreal! What’s the latest?
I ought to upload some photos, its looking pretty cool. I've replaced the intercooler (with Forge item) and all the IC ducting with aluminium hardpipe. Changed the pre CAT O2 sensor locations in the exhaust manifold to OEM location. The intake manifold and all cold side pipes are covered in gold heat reflective tape. I am in the middle of fitting a Turbosmart BOV controller. Following that I need to wire in an N55 MAP sensor and fit the larger injectors and new spark plugs. Then it is time for mapping :). I've paid for a BPC (Bimmer Performance Centre) map which will be an Alpha N tune remotely done from the US.
If it’s an Alpha N tune why do you need the map sensor?
I was alway led to believe Alpha N works off of angle not vacuum like a map sensor?

How much was the kit originally? I was tempted by it but don’t fancy going through all the hassle that you have.

Bet you can’t wait to get it sorted now

I'm not sure how much the kit was originally, something like £3.5k, however it has cost me a chunk on top of that p*ssing about and I am using very little of the original kit! Just the supercharger, SC oil cooler, SC engine mount bracket and a couple of the charge pipes. I have learnt a lot though and enjoyed tinkering. If I was to do it now the only difficultly would be getting a bracket to hold the supercharger to the engine block. The main hardware is relatively simple, its having the BOV controller and then the R&D by people like BPC into the ECU and injectors that has only really materialised in the last year. I think using the Rotrex charger on a 1 series is also a bonus as it allows you to run an intercooler. I can't see how you'd manage that with the ESS kit and their Vortech unit as there is so little space in that part of the engine bay! I think the only alternative would be meth injection.

My understanding is that an Alpha N tune means you can run without the MAF but can utilise a MAP sensor? I think the M3 CSL uses a MAP sensor due to its carbon air box and an Alpha N tune? Anyway I'm no expert...as long as it works I'm happy :).

That’s interesting so knowing what you know now you could build this set up for less money?
It will be a great once all up and running.

M3 has a maf as standard, the likes of evolve tune via the alpha N route which can be poor if I’m honest but essentially will work and can be tunned

M3 csl uses a map sensor which works on vacuum and is a far superior system to the alpha N route

Alpha N works on angle which is basically a limp mode/fallback if one of the other systems fail,
It works off of the throttle position sensor and engine rpm but it can’t meter air flow like a maf or map sensor hence why it can be a bit lumpy and jumpy , it will still make power but it’s not as smooth as the other 2 systems also driving up say a long hill will be crap,
So I personally would want it running off the map sensor and would steer clear of any alpha N



Only reason I got involved with this is because my mate done a full csl airbox conversion with and alpha N map and it was horrible, so he went done the map sensor route and the difference was ridiculous so much better

Hope this helps after all the time and effort you have put in you want it right.

Thats good to know. The N55 MAP sensor and harness was provided by BPC along with the injectors and their tuning box so assume it will be utilised in the tune (whatever form that is :))
