IIRC (it was bloody early and im VERY glad the roads were empty last night, apart from the lorry drivers parked up at the side of the road ) it did a 3.1 FATS time consistently without WMI.
With WMI the most we did was 2.6 bar between 4 and 6krpm which resulted in a 2.7 FATS. It pulled 2.4bar consistently for 2.8 FATS which was a little peaky at 5krpm so we went with a linear 2.2bar with WMI between about 3.9krpm and 6.4krpm i think, giving us consistent 2.9s FATS.
You have to bear in mind we were mapping this in the early hours with 13-15c IAT anyway. The .3s difference would be far more pronounced under "normal" IAT during the day, with the WMI being entirely consistent regardless.
It became clear over the weekend the Milltek cat-back system was a major restriction on the previous setup and likely one of the biggest factors in it only running 431bhp. The Milltek system which AFAIC was 2.75" and on-the-limit was infact a 63mm or 2.48" diameter which experience for Will, JP and Dmitri says was probably very very lucky to do 431 last time. It also explains some of the boost characteristics.
As a result i turned up with Dmitri to map the car last night to find Chris and Will finishing the install of the 3" side-exit pipe
I've no idea what bhp it is running but my god, it is phenomenally fast!
Some other interesting events from last night - one of the first things Dmitri noticed was the original MAF fitted was clearly not running right, so the original map needed some tweaking, or rather a brand-new profile to stop the car running very lean. It really does pay to make sure these sensors are all working right!
We had a major boost leak occur when testing which we traced down to the ISV area. No idea how (he did try to explain) but Dmitri knew pretty much to the exact area where the leak was occurring just from the logs which was very useful at 11:30pm with nothing but a flat-head screwdriver at the side of the road
We stripped down and checked all the vac pipes and then ISV pipes and clips and could not find the issue, but with the car running it was clear there was a massive leak near the ISV. Turned out to be the bolt missing from the reverse inlet manifold which holds the ISV pipe and oil dip-stick that clearly made a bid for freedom after working loose with the solid engine mounts, lightweight billeted flywheel and new exhaust system vibrations, further aided with 2.6 bar of pressure and some 1k to 4.5krpm 6th gear WOT runs :laugh:
Even given the hour Will was on support and came to our rescue with his facilities, tools, a spare bolt and some loctite!
Other than that it was all good and a relatively hassle-free night
Again, i'm not sure i can state this enough... an absolutely massive THANK YOU and loads of love to:
Will from VRS for going to unheard of lengths, getting the car to the stage it's in and providing mechanical support well beyond the call of duty. There is no way this car would be where it is without you.
Chris from VRS for having multiple early mornings and late nights working on the car with Will including the 5am Sunday morning start to finish the WMI install and the 9pm working your magic to finish last night with the exhaust - and those are just the ones i know about. Again, way beyond the call of duty and highly appreciated sir.
Dmitri (Prj) for not only providing quality custom mapping service but doing it in throughout the night until the sun rises whilst being medically incapacitated ( mapping the car with a trapped back/neck nerve and dosed up on painkillers was seriously hardcore and not for the faint hearted!!) but for battling technical problems, cancelling your return flight home and staying around making time available to complete the map. But please, get a new ****ing laptop for next time
Simply, i can't thank you all enough
Right now im trying to keep my head down in the office after barely a couple of hours sleep, so time for some pictures -
Futher brake and exhaust porn:
I'll do a proper video at some time soon as well to show the acceleration of the car but this was to try and capture the exhaust. I can't quite describe how you feel it in the chest when it hits the launch control limiter (and for the eagle-eyed amongst you you'll notice this was before it was mapped and as such not running optimal fueling)
Getting started at around 10pm...
And finishing off at 3.30am...
I think there are a few videos around as well
Oh, and just to add, in keeping with the theme of the car Chris noticed the after-run pump was sounding very rattly and noisy as we rolled the car out of the garage
Great news in the end, makes up for the trouble I guess?
Is the side exit a temporary solution because of little time?
Yes to both, although the side-exit pipe is rather awesome i have to say, it does leave something lacking at the rear and i feel a twin-exit pipe is fundamentally characteristic of the car.
