Enhancing a 650s
Discussion
Hey,
I'm new here or should I say I'm back?! Not been on forums for years, but it feels good to be back!
On the subject of 650s, I always Antify my cars as the wife calls it and it means not what the car is, I allways tweak the hell out of what I have, of turbo my microwave if I could!
So with the 650s, I'm def going to Decat it as I'm a child at heart that loves flames and drifting. For this I think Larini are prob the most cost effective option off the shelf that I've found yet, I could fabricate my own as I have been in the automotive business for years and have built racecars too, so at £3k I would, but circa £1000 I'd just order the Larini test pipes as they call them, they worked a treat on other cars.
Regards exhaust/cat back on the 650s as it is, I'm thinking Akrapovic, I want titanium as I don't think you can beat the quality that goes with it, anyone have any other options?
Finally would be a tuning option. I've remapped ECU's in the past and have used plug and play tuning options, both have pro's and cons, what is your view on a McLaren? I know the 650s runs rich like most other cars and I only use 99 Octane fuel and well service/look after my cars maintenance wise, may not drive them like that, but ive not had a component failure yet across most marques, so does anyone have any input? I think from my research I've come down to Fabspeed for this to realise over 700hp, but again, can any of you give me a few words of advice?
Thanks in advance guys and good to be back!

ah cool, i might see you around then!
Had an interesting chat with Throney today and he basically said don't do anything to it except cat back rear exhaust section...
He had major issues with remapping the 650s as you can't dyno it apparently, so out right said that he doesn't map them anymore as he's had some problems with engines blowing up as other than a dyno you can't run wide open throttle for long enough and under enough load to be able to see exactly whats going on.
He then slated the idea of decatting the 650s as it ruins the secondary lambda signal/scale to monitor the air fuel ratio, so this can cause a lean situation as well, he offered me a bespoke rear exhaust system tho, so its back to the drawing board really.
Has anyone else heard of any issues with MP4's or 650s after tuning???? Its the opposite of what I've heard to be fair and I've got enough tuners offering to do work without any hesitation or bad rep...

Thanks for all your replies guys!
I've been doing some more homework on it and from what I've found out, it is actually possible to dyno a 650s! I haven't tried it myself yet, but that is exactly the first thing I'm going to do! I'd like to see what power it actually has and have a proverbial bench mark shall we say, so I'll run it through my local company and see if the process I've been given works to put them into a dyno mode... We'll see. I'll try and export back.

Thanks for the responses guys, all very valued and understood.
However, as well rounded a package as the 650s is, I do now after just over a weeks ownership find it lacking in power at top end, you can feel it drop off and there is absolutely no need to rev it past 7000 as nothing happens. To change early in the rev band to keep a car in the power band takes some of the fun out of it. I'm very well accustomed to driving around problems having raced for many years, owned race teams, my last race car was a 2012 championship winning a Porsche 997 GT3 Cup car... but it's from this, that I can feel the car has more to give. I can feel it being held back, for whatever reasons and it's from this, that I know the car is a package as is has more to give that is going to unlock it. The software remap simply gives you what the hardware is capable of and the tuning is a way to make it all sing together so to speak, so we'll see and I will of course feed all info back guys!
I'm not a company anymore pal, just single me that loves to tinker and perfect things.

Having now seen you on the road , I can vouch the last thing you need is more power 
I was the silver 650s going northbound on the A34
PS - Black on a 650s looked bloody good !!!
Haha I wondered if it was you! I sent you a pm on 'that other forum' before, to say hi!! 😁I was the silver 650s going northbound on the A34
PS - Black on a 650s looked bloody good !!!
Your car was seriously clean today, looked very nice indeed pal!

Are you seriously expecting a relatively small capacity, highly boosted turbo engine to have the same powerband characteristics of as a high revving normally aspirated engine? 
Mclaren have tried to keep people happy by allowing the engine to rev up to 8500 which is quite unusual for a turbo already. Expecting it to continue producing power like a NA engine high up the rev range especially as it very definitely hits you with a huge amount of torque from 4+k is a bit unrealistic surely?
Erm No, that's not my viewpoint whatsoever, but as much as I can understand that it is plenty for 90% of drivers, you must be able to allow that some drivers that have experience with a vast plethora of cars, with all the variable characteristics of petrol, diesel, NA and forced induction, may be able to sense and feel an engine that is being held back through software or where compromises have been made to cater for the masses. As a purist and perfectionist, those things really get to me, so as I have the desire and ability to do something about it with my car, then why not?? If it gives me a car that I know is underneath, just waiting to be released then why not? If you're happy, then.im perfectly ok with that.

New software will allow it to rev, keep Boost and pull harder to redline, I'm not asking for Cup car rev'ability, but it's proper crap when you can sense it's being limited and isn't natural...

Just seen on FB that ES are starting to tune mclarens... just done a custom tune on a MP4-12c and tested the 100-200kmh run
Stock 6.1
Tune. 4.8
So on par with the 720s with the tune ...
Sounds fair, what is their website pal, I e just found an ES Tuning, but they're in Turkey... Stock 6.1
Tune. 4.8
So on par with the 720s with the tune ...
