WI on RSQ3..?
Posted: Fri Jul 08, 2016 9:22 am
So I've had the car mapped by my mates at MRC and I love the map (as usual) but they confirmed that the standard IC are crap and the intake temps rise too much to get the best from the engine.
I have kept the pre-cats but gutted the main cats (with better high rev performance and a little extra noise) and I plan on installing water/meth injection INSTEAD of changing the IC's. The reason for going down this road (rather than larger IC's) is to minimise the pressure drop that comes with larger IC's and as I cannot face stripping a 6 month old car to access the IC's...
I plan on using the very smallest nozzle (0.75) pre IC and then a slightly larger nozzle immediately post the IC. The reason for doing a small nozzle pre IC is to assist in heat transfer of the IC.
My question to those in the know is: What benefits have people seen by doing WI on the 5cyl unit?
I have done WI to great effect on the C5 RS6 and the B7 RS4.
Thoughts?
