I have made some changes to my set up
I have removed the buddy club rear muffler and installed a 2.5 inch muffler
installed new superchargewr pulley
increased the water meth injection with .7 sized nozzel
these changes have netted this increase
My graph is very smoth compared to many other graphs i have seen on oz honda. someone may know why other graphes are so lumpy
Have you got any graphs with and without watermeth?

any updates ?
have you ported the SC yet as it will make a huge diffrence to power and heat
Im on a poor tune @151kw atm
there are lots of mods you still havent mentioned if done or not
I have had the dags cleaned up on the supercharger outlet when it was serviced and had an oil change.
What mods are u thinking about I haven't done
No I dont . It does not make more power with water meth.
Im not sure how you have gone about it - but you cannot simply inject water meth and expect your car to make more power. Contrary if you inject water-meth ontop of your normal fuel mapping, you will over richen you fuel mixture. This will cause the combustion process to drown (yes you will loose power ) and even possibly cause misfiring (depending on how much your injecting).
The whole purpose to water meth is to have you car tuned with this equasion involved in the fuel mixture - This means your fuel mapped units will be lower as the water meth is actually a source of fuel. The benefits of water-meth injection are A - cools your intake and combustion charge, B - Reduces the tendency of your fuel to detonate (this is like running a high octane fuel) - It is because of this you are able to run more ignition timing in your tune and hence make more power.
There are some risks to this depending on your setup. Firstly if you are only running a single injector before your throttle body (i assume you are) - you do not have a controlled amount going into each cylinder. Some cylinders could be richer or leaner and the tuner really would have no way in knowing as they only use a single o2 sensor at the back of your exhaust (averaged out o2 reading of all 4 cylinders).
If you are using water meth to extra more power i would strongly recommend useing a low level switch in your water/meth tank, and using that to trigger a input on your ecu to bring on a different table or even a generic output to add fuel, reduce timing etc.
AND - buy a wide band and have the 0-5v signal datalogging into your ecu and setup lean-out protection with a conservative value. e.g. Over 10psi, a/f under 12.5 etc
If you are running injection and you dont want to play around with the fuel mapping all that much, ditch the methanol and just run Demin water. The methanol will do you more harm then good if you dont use it properly..
hope this helps

any updates on yours yet
Ive had myn retuned and now have lots more KW's :P
I have not had time to do any more changes. When I do I will be adjusting the overlap of the cams. This is where the improvement will be. The cars drive great more power will just be more wheel spin ripp n up the semi slicks. = more fun

This is too true. Just run water if you are just looking for cooler intake temps.
Exactly right Grifty. I started to think about intercooled supercharger setups for this fine gentleman but realised noone else put that idea up there so I thought maybe it may be too much money / work for him to incorporate that one in now.
