Thanks Bill and Alex - beat me to it!
Latest update...
On Saturday I ran over to Merlin to pick up a Revotec 76-63-51mm reducer which I then dropped off at Bill's who mated this onto the bottom part of a Forge TIP he had lying around, reducing the bottom of the TIP from 51 to 44mm giving a perfectly snug fit over the turbo. Since modifying this TIP and moving the MAF 3" further away from the DV return Bill hasn't seen any further stalling on his test runs
As this Forge section of the TIP is blue I may get onto SFS about making up a black version if possible so it matches the rest of my pipework, or I could even probably get away with a Samco 51-45mm reducer if needs be.
Bill then finished off his mapping by dialling in 8.25 degrees of ignition advance running a 50:50 mix of water/methanol. Previous results on other 1.8T's indicate that every 3-4 degrees accounts for 10 BHP so this is a nice little increase on top of what the turbo is already producing. Yesterday's intake temps were showing 16 degrees which I'm more than happy with so the intercooler and WMI look to be doing their job nicely.
The car is logging just over 220g/s through the MAF which using a scaling factor of 1.3 equates to 286 BHP so with the WMI I would hope to be pushing, if not breaking the 300 BHP margin
Peak boost is 1.8 bar (1.6 requested IIRC), holding ~20 PSI/1.4 BAR at the redline. As I wanted an aggressive map that felt similar to the power delivery of my previous Revo Stg 1 setup Bill's mapped it in such a way so as to give a nice punch after every gear change which then levels out to hold the power nicely all the way through the revs.
On Sunday afternoon I went over to pick the car up and was looking forward to reporting back on how the car feels, only to find the clutch absolutely sh*t itself on the way home, slipping through every gear even on partial throttle and skydiving the revs to the redline - typical!
I didn't manage to get on a long enough clear stretch of road to properly give it some before the clutch started slipping (Sunday drivers...) so I've still not felt just how much power the car is now capable of putting down, but I do still notice a massive
massive difference than before from the short bursts I was able to give it before the clutch crapped itself. When I pulled up at home there was a nasty smell of it burning outside and with such aggressive power delivery its just too much torque for the standard clutch to take, as was always pretty obvious. I had just hoped it would hold out long enough for the journey home!
So, next up I'll be sending the car over to Alex at Backdraft for a new uprated clutch, lighter flywheel and Peloquin diff which should handle the abuse much better
After that, I need to get my intercooler pipework beaded ASAP to prevent any unfortunate incidents on the side of the road when a hose pops off and then look at getting the rods uprated for peace of mind. So close and yet so far!
As has been said countless times before on this forum, huge thanks to Bill for all his hard work and patience with the car over the past couple of weeks, I couldn't have left the car in more capable and helpful hands and for that I'm extremely grateful - top job
