The annoying thing is they’re the exact same but ours is detuned for EU emissions that’s why it’s down on power. I don’t feel I’m missing there really either but it’s always good to have moreYorkshire_Z4M40i wrote: ↑Thu Jul 29, 2021 3:26 pmYes you make some solid points here... Especially regarding true output seen on a rolling road. I do sometimes get the feeling it's got a little more horsepower then then BMW state, but then cant get that nagging feeling to stop, that I could have more haha. Especially because of the stated differences between the US and UK versions, even though it's the same B58 engine, etc.Argyll Andy wrote: ↑Thu Jul 29, 2021 2:04 pmThe whole chip thing seems like a bit of a con. When I looked into it the explanation I was given is it’s so expensive because they switch the whole ecu out, which also gives you a resale item but not anywhere near recovering your costs I’d imagine.Yorkshire_Z4M40i wrote: ↑Thu Jul 29, 2021 1:17 pm
Aww I was starting to think the same... Looks like AC Schnitzer are the only option then, if you don't want to risk invalidating your BMW warranty. I've been eyeing up all the AC bits to be honest yeah , but getting thier full kit is around 16k The chip, suspension and exhaust bits are a pretty healthy amount in thier own rights too though. I don't mind the stock sound really, but I do like the idea of around 400bhp instead of the 335/40/50bhp (read different accounts) we get in the UK
I have to say personally I’m quite happy with the suspension. I gave it some proper stick on a very twisty part of the Oban road on Sunday and not once felt it wanting. The only issue I had was my green faced passenger who also commented about how well it handled given the rate we were moving at
The whole package is expensive but if you want upgrades and to stay in warranty it looks like this is the only way to go.
I would be interested for someone to get theirs on a rolling road, none close to me unfortunately, to find out what the actual power output is because coming straight from a 35iS to the M40i it states on paper they’re practically identical, from the drivers seat I’m not feeling that to be true. Even after a days test drive I said I thought the power had been understated for some reason. Caught a couple of articles, which I can’t find again where a few these were rolling roaded as stock and the figures for the 3 cars were between 368-382. If these are correct the AC mod is even more expensive for the small increase to 400
Also I recently saw a video by a well known online car reviewer (it has "Car" in the name followed by a word that rhymes with "How"), where they drag raced one of ours against a Supra, and ours got absolutely spanked! They say they have the same power, but the reviewer said the Supra definitely had more than the 340 declared. Needless to say, that didn't help with the nagging feeling one bit either! haha
As for suspension, I reckon you're right to be fair... Its not bad at all really... I've only had one or two moments in a bend with slightly bumpy tarmac, where it's not felt as locked down as I'd like, enough to push through and power out of it... But then again, a lot of cars in this price bracket and power band probably wouldn't do any better either. And I'm pretty sure the Z4 M40i beat the M2's time around the Nurburgring too, so that's saying something performance and handling wise I guess.
Soooooo what I think we both need here, is for you to get the upgrades installed and then if they are any good, I'll get them too... Hos that sound? Haha
As the three of us are discussing maybe a change of exhaust would suffice. So either you or John get yours on a dyno then he’ll buy an exhaust because he has a habit of collecting them and we’ll have a choice of 3 2nd hand ones within 6 months
