1.4 BAR on ceramics
 

Hi,

I have a GTR R32 rb26dett. one of the turbos with steel internals (we had to change it to steel after a failure fitting custom down pipes). I wasn?t worried about having the car running 1.2 BAR here (12,000 feet /3800 meters above sea level ), but now I?m going to sea level to race it, and was wondering if it is a good idea to place an M7 nozzle (7gallons/hour) instead of an M5 nozzle (5gallons/hour) since I?m going to put 1.4 BAR and 97 octane gas. I?m planning to run 50/50 water/alcohol mix. What do you think?
Would this pressure cause any troubles?

I have a AFC neo to cheat the ECU a little bit in case I?m runing out of gas with that pressure.
Any help will be highly appreciated.

Cheers,

Cid

main problem will be secon ceramic turbo itself, as its ceramic turbine blades are know to broke prematutrely at this boost level.

rest is like usual, tune fueling to as close as possible to ideal values at 1.4bar together with knock-free timing.

Thanks for the reply Raddy.. As far as I know, in effect water alcohol would decrease the temperatures on the cylinder... and as a consequence would decrease the exhaust gas temperatures? and well I was wondering if on the rb26dett would be better to have the M7 nozzle... the problem may be too much water alcohol injection..
What do you think?
