Having just returned from a road trip across europe (2000 miles) I was having to monitor inlet temps carefully due to my perception of possibly dangerous temps.

I have a PE turbo set up (+ aquamist) on my 2003 MR2 rioadster, with 9psi peak

with air temp readings available at both the filter (MAF) and also the last bend as the forced air enters the engine.

THe after market digital temp gauge I have fitted just before the engine has a preset temp warning buzzer set at 65 deg C. I found that at constant speeds of 80-85mph on a reasonably warm but not roasting day inlet temps were reguarly setting the buzzer off. Obviously at times of boost the aquamist would kick in and drop the temps efficiently however this of course doesnt help if cruising in the outside lane with hardly any acceleration to speak of.

If any of you guys have a similar set up (no intercooler) and have a temp gauge after the turbo I was wondering if you could post what temps your reading when 'cruising' ?

I found the ambient temp didnt make a great deal of difference until the evening when the temps dropped significantly, but even then I couldnt go over about 90-95 for ten minutes at a time without the alarm going off

A friend who was also on the trip has a GT4 turbo (CS) which of course being toyotas old rally car is fully cooled via a watercooled charge cooler etc, his temp readings in general only cause him concern when he reaches 40 degC after long periods stationary in traffic etc. So for my 'two' to be 65 deg when on the move causes me concern

any guidance on example temps or safety levels would obviously be much very much appreciated.

cheers
