My new Ride....

If you "tune" for WI you always do run the risk of it failing eg water clogging etc etc therefore you risk the engine, If dont tune for WI but use if as a safe guard then its brilliant if you run out of water of get a blockage then you are ok as your tune was without WI.
I would say tune the car to 1.2 BAR as loads of guys have mapped to this boost level on T51 on pump fuel 99 vpower not tescos rubbish, add WI for safety but you will lose a few horses.
If want to push the limit then run 50:50 mix and get it tuned up to 1.4 BAR but agree to take the risk.
Safest would be to run race fuel on track at 1.4 BAR but as we know race fuel is very expensive.
Believe me I run 10psi on the road and thats scary fast, will be going to 1 BAR on pump fuel very soon and on my porting/setup will see me at 550 at the fly, then will being doing a race fuel setting at 1.3 BAR and hopefully nudge the 600fly barrier, which will kill most 800bhp skylines and Supras on the strip

Thanks for the advice mate.... Im going to see your tuner in the a few weeks.

99ron sounds fine. The highest octane we have here is Gull F10. Its 98Ron with 10% Ethanol in it. This is what I use.
 
My FD is tuned to 1.4 bar & 1bar for the street. I added WI to drop air temp and belive me you notice it when you dont have it. The difference between WOT at 25c plus and WOT at 13c and lower is totaly insane. Its like driving your car on a 5c morning during a 28c summer day. Im sure if any of you have notice that your cars seem to pull much harder on a nice cold morning than they do during a warm day.
 
I have not tuned my FD to the WI. I just use it as an aid in keeping the power consistant. If the air temp stays cold the power stays up.
 
I can hook you all up with the kit I use. Its made here in NZ by PINZ. Has a pump that is designed to run dry & the base system costs $1000 NZ or 380GBP plus shipping costs.
