Rough start after WI installation...

[Chuck-S4]

Small problem with motor start / car ignition.

An Aquamist 1s kit was installed on an Audi S4 (2.7 Twin-Turbo); system is working great under WOT, no doubt... Max Fuel flow is approx 2100CC/min and we use twin 0.5mm jets (total of 400CC/min), (ratio slightly below 20%), running 35% Methanol / 65% H2O (windshield washer fluid). The Aquamist system is set to 8PSI.

We went WOT for a few test runs, everything was fine... We let the car sit (immediately after WOT I must confess...) for 60 minutes. We went back, motor still mild-hot, and started the car. Tthere was the problem; it did hesitate approximately 2 seconds before the motor actually started (like a cold start on C-16 - Xylene / Fuel mixture). After that, the motor runned ok.

Is it a normal? If not, is it mixture related (methanol causing rough starts)? or is it because I have excessive flow (twin 0.5mm)?
