am useing AP 3.5 ICs , as you know i tried 2 ways to make better results for iats under full throttle , and here are my My experiences :
the co2 is good to take out the heatsoak from the ICs and make it cold again but will do nothing under full throttle.
the meth injection is very important to run , i think you saw my thread about data log , meth injection lowered my iats from 38c to 28c under full throttle and this is very good ..
the main problem am facing now, that i should run methanol all the times to support the boosted air inside the engine and lower the IATs to protect and avoide the knock .. am afraid to run the methanol injection with race fuel ( vp109 or c16 ) , if i want to boost 1.8bar as example .. it will be much octane inside the engine .. and this may harm the performance ..

you can always datalog it, turn boost up .1 up after each run. and re datalog, see how the car feels. start at 1.5 and go to say 1.8.

My supercharged 2006 Carrera S had TPC Racing's Air-to-Water heat exchanger...compact, solid, did it's job quite well...no leaks...no refilling...always cool to the touch.
My supercharged 2002 M3 had VF's Air-to-Water heat exchanger too...same as above.
Granted, both superchargers were producing only around 6 lbs of boost.

still thinking about it ..am just worry about the IATs , i do not want it to go high , once the weather here be cold like 5c or 10c i will run just race fuel ..

Milou is very knowledgeable and has a lot of hands on experience with meth unlike me so I'm sure 103+meth would work since his car has boosted to that level before. But from a theoretical standpoint, VP109+meth would provide greater knock resistance which presumably would allow you run higher boost more safely. Maybe a bigger CO2 sprayer would help??

correct me if am wrong , but running too much octane in the engine will harm the performance , this is what everybody said !! thats why am Hesitant and confused , i do not want to lose the methanol Advantage as cooling the iats , and in the same time i want to boost more than 1.7bar so i must run enough octane to protect the engine ..

I think losing performance with high octane fuel is an over generalization. It's so complicated. Stoichiometry of fuel, btu of fuel, octane rating, fuel composition, cooling effects, plus how you're tuned to a specific fuel all plays into it. I don't think you will lose any performance with MS109 vs a 103 octane fuel. If anything, you can probably run a little more agressive tune and gain a little in performance. The slight timing decrease you see might go away.
. I think Dave is right, it's all about tuning

scott softronic cares of me alot , we are talking alot via emails to fine tune my car .. will see what the car gone do ..
for now , any more ideas how to lower the iats ??
thanks
