I have my setup sorted out at the moment.
Stock turbo's I have atm kick in at 3300
-5 will kick in at approx 3600-3800
Adding more low end punch with adjustable cam gears and getting it tuned for a bit more pick up in the lower end range.
Rest is good for what I want which is 300kw at the moment. But have the parts there if I want to chase more later.
My car setup is more for Tarmac rally than track I don't want punch from a stand still I want a powerful mid band to rev out to redline, the way I drive the spur with what I have I am sitting at 4000rpm through the spur keeping power up as the car only has 180kw currently and I can keep up with you guys as it is
As my driving style is to sit in the mid range having the -5 spooling or near ready as I come onto power out of corner increases corner exit speed and provides a lovely 4 wheel power slide/drift.
And yes all handling aspects and braking have already been done and bedded in before adding power to get the car setup right from day one.
The guys at RE haven't steered me wrong yet and the car has been getting better and better as we work through legacy age part replacement, and upgrades where required. My car will look like nothing has changed when they have finished.
