RE: G Power launches 440hp M140i upgrade
Discussion
I have an M135i Lci and it’s pretty much what everyone else says. Stock power is enough to overwhelm the standard diff/suspension. It severely lacks feel as well. But as a point and shoot weapon there is no denying it is fantastic.
I had a Porsche Cayman S 987.1 before the m135i and in terms of feel and suspension composure it’s no where near but in terms of point and shoot the turbo in the m135i would edge the 987.1, just my opinion.
The engine (touch wood) has been mega reliable in the m135i. The Porsche, well they have a reputation for a reason and I fell victim to the bore scoring. Such a shame as the Porsche was beautiful to drive.

As standard 370 lb/ft of torque from 1400 rpm, 70 plus more than a V8 M3, easier to be out of the power band in the M3 than having any lag on the 140i, especially with an 8 speed auto, remember its still a three litre straight six, its a well sorted installation and the boost pressure isnt that high as standard.
Not saying its better than a V8 M3 but it isnt laggy and its as fast most of the time, faster in a lot of circumstances.

Cheap leather.
Cheap crap manual seats unless leccy.
Laggy. It’s turbo and it’s laggy. Not bad but it lags.
8spd is boring. It’s ok in a diesel or a normal car, but it’s not a sporty box. Works fine with a turbo engine though.
Cheap thin carpets.
Fairly bland noise. I gather most is via speakers.
The V8 M3 will be on another planet for having fun with the performance on hand.
Plus the E9x generally are much nicer quality, with the M leather even nicer again.

I do trackdays in it, I have done 2 and a half (one evening session) so far...
Gearbox is 99% as good as any DCT on track, but probably 120% as good on the road, so that's a win.
It generates peak torque at around 1700rpm (over 300ftlb can't remember exact figure) so no idea how you can call it laggy.
If you want laggy try driving my old Scirocco tdi which at 2000rpm produced 90hp with my huge turbo on it
Leather seems perfectly good to me? comparing it to various Audi's and Jaguars that friends/family own.
Sound is nice with m performance exhaust and coding changes to remove the fakery from inside.
The difference between E9X interior and F2x is actually very little and in many ways I actually prefer the F2X interior in terms of appearance and feel especially the idrive
M3 sounds nicer and is a little nicer in terms of "out right hooliganism" and of course is an "m3" which for some people is great - that being said on the track the standard brakes are naff and there's not really much between them on track unless it's a very high speed circuit IE silverstone national .
Also the reliability of them is pants I personally know of 3 people who own E9X m3s and all 3 have had the shells fail and they are all under 70k.........

I'd swap the fronts for M4 seats which are great, but the red/orange M3/4 interior is a very slightly different shade to Coral in the 1/2 series.

I think seats are a personnel thing though - I found the standard seats (mine had electric memory seats) the most comfortable I'd ever used on longer journeys, and held you in respectably. Plus I think M-sport seats (not sure which variant, but probably shared with an M-car) were an option IIRC, although no doubt a ludicrously expensive one..

Its not the most exciting thing in the world but it goes like the clappers and I wanted a newish car that wasnt going to be hard work and expensive to own.
"Most" of the noise isnt via the speakers, some is apparently, 20 percent I read.
Gearbox is very impressive, would have preferred a manual for those occasions when I can use and enjoy it, but for the rest of the time the auto is fantastic, I have a problem with my left foot at the moment so the auto suits.
Am sure an M3 is more fun, which is sort of what I said, could have got one but decided to be a bit more sensible, ageing M cars can get very spendy whereas this should just work and need normal maintenance until I change.
They have their shortcomings and arent the answer to everything but for the money its a pretty good package.
The cost to run an M3 is in a different league, they are heavy cars and tbh not that much fun unless pressing on. For the real world IME a tweaked 130i is a better car. A tweaked 135/40 maybe an improvement but I think they’re probably too much and lack the basic feel of the older car. Either way you need an LSD and suspension change to get the best from even the standard outputs.
I own a standard M140i, and making it faster would be pretty low on my list of priorities.
I'm happy with the car as standard, as it does everything I need it to, but if I were to start spending money on it, I'd go:
LSD
Dampers
M4 lower control arms
M-Performance exhaust system
Remap
In that strict order. The first three would make it a faster real world (and nicer driving) road car than a remap, in my view simply because the engine isn't the limiting factor in many conditions. Traction, license preservation and very occasionally, damping most certainly are.

440hp has been done on the m140 engines quite a lot recently since the b58 ecu got uncracked.

I would get an LSD and the other bits but its quite a shopping list, probably five grand plus worth ? and as I said earlier, probably better spending a bit more on a full M car.
I found it woke the engine up nicely but now it really doesnt need any more power, probably just put it on a par, or just slightly ahead of a standard M140i power wise, with the M140i it probably doesnt really need any more, quite a bit more torque and nearer to the chassis limits anyway.

A 245 profile rear tyre seems very small for 340bhp and 379lb ft. E46 M3 was 255 or 260 with over 100lb ft less and a proper diff.

The M4 TS do not fit, you need some spacers made up.
The M4 control arms fit but move the wheels slightly forward in the arches.
For the money you can buy Dinan or Millway camber plates (this is what I will be doing).
I use Pagid RS29 pads over any of the OEM stuff which is still a bit naff for proper track use.

I'd still have the E92 M3 with the 4.0V8 with 8 ITBs and 8400rpm redline S65 though.

Apex reckoned their ET58 EC-7 and ARC-8 would allow 265/35s but possibly need a spacer. I'd been looking at the EC-7s in 8.5 and 9.5 F20 offsets as a possible replacement for the OEM wheels, albeit likely with 235 and 255 rather than 245 and 265.

Can the standard out the box suspension give the driver confidence with this sort of power?
I have a E82 125i which has been tuned and yes its older and less powerful. But the suspension is dogs
t to say the least.
I used to have an E82 135i, twin turbo N54. I started tinkering and the engine overtook the chassis way too much. A remap on its own had it at 370hp, and an intercooler and downpipes had it at 435hp soon after with another remap. The thing was rather radical with huge torque (500lb-ft) which was a challenge sometimes with a short-ish wheelbase.I have a E82 125i which has been tuned and yes its older and less powerful. But the suspension is dogs
t to say the least. To compensate the power and get it to perhaps one of the best handling and confident cars I have driven, I did the following:
- Wavetrac LSD
- E92 M3 front ARB and mounts
- E92 M3 front tension rods
- E92 M3 front control arms and bushings
- E92 M3 rear control arms and bushings
- Bilstein B8 shock absorbers and Eibach springs (otherwise known as Bilstein B12 kit)
- 8.5/9.5j wheels allowing wider tyres, Michelin PS2's at the time.
That essentially put it at 1M chassis spec. Maybe this generation of 1-Series has a more robust chassis to start with, but in general I really don't like the way they look and they have that horrid chav image that most entry level "prestige" cars have, and a driving style to go with it that we've all come to know and hate.
140i is nice enough.
The point is the last thing it needs is barrying up and making ‘better’ where it’s already overly effective at the cost of all else... point/shoot into pointlessly high and unrewarding speeds.
And yes it lags. Put it in 5th (in the 8spd auto) at 50mph, go WOT.
Does your head snap back? No. That’s lag.
It lags all over. No it’s not the end of the world, but with 400bhp tunes it’ll be worse... and it’s the last thing you want in a ‘drivers’ car.

You clearly have no idea what "lag" is.
What you're describing, albeit hilariously badly, is boost threshold.
And what makes you think a 400bhp tune will make that worse? Even if it only made extra power on-boost, it wouldn't magically start boosting later or producing less power off boost.
