So, a week has flown by since the turbo kit went on and I can honestly say this is THE single most awesome modification I have ever done. The R is running better and stronger than it has ever done and all the logging that Steve at Statller did when setting it up on the dyno shows that the car is running exactly as it should. Fuelling, timing and boost are all spot on and the car feels very smooth on the road.
Negatives?
The lag - It is there if you press your foot down in a high gear at low revs, but you'd be daft to do this. It takes a little adaptation and re-learning on
how to drive with this set-up over my K04 or Loba set-up although the benefits far outweigh the momentary lag.
Launch control - More difficult to get just right, but you don't really need it as it will still do 0-60 in under 4 seconds without it!
Positives?
The power delivery - Relentless and sooo seductive, where the K04 starts to slack off at 6krpm, this set up simply pushes you back hard into the seat all the way to the redline.
Fuel consumption - Appears to be better.....unless you press the fast pedal.
Driveability - the car just feels better to drive for not having the huge hump of torque low down in the rev range, smoother and more linear. Part throttle is excellent.
Speed - The obvious advantage really. This thing hauls ass. Make no mistake about it a stage 2+R wouldn't see which way this car went. Conservatively speaking, this will now do 0-100mph in under 8 seconds. The quarter mile time should drop significantly.
Safety - Not one I would usually put down here, but it has to be said that overtaking is a breeze and it seriously reduces the amount of time you are on the wrong side of the road and exposed.
Noise - Goddam it this thing makes a sound like a jet fighter at full WOT!
Flames - I have them and it looks mental!
Cost?
Well for my specific set-up it isn't cheap, but something like a CTS kit with a GTX3067R would yield similar results running off the GIAC BT map and wouldn't break the bank.
