Injection while cruising and general setup questions

[Richard L]

Th temperature is quite high but it is quite normal for a non-intercooled and small turbo.

The placement of the jet for general cooling should be as far away from the throttle plate as possible. Cooling all the metal in the inlet tract along the way is a good thing especially you injection at vacuum.

Since you have a programmable system, you can set the spray at a very small duty cycle during vacuum- possibly at 5-10% opening, it will have the same effect as a cool day. As soon as you are on boost, you can ramp up the duty cycle immediate (compensate for the delay on fast spool up turbos). As soon as you arrive at medium boost, make a steady increase from then onwards high boost.

It is just an idea. If you go for the aquamist 2c system, you should be using a 0.7mm, approcikte allow you to spray between 10-20% w/f ratio (rough estimate).
