What coolant temp are you guys running at?

Would a blown motor suggest higher coolant temps?

When not uder boost temps should be be same as usual. Under boost they tend to go up Like durring a hard run it is not uncommon for temps to rise fast

My car runs at 170-175 with the 160* T-stat when I'm moving. What radiator are you running ?

I have a 180 thermostat but the car operates at about 205 on the freeway and about 215 in stop and go. I assume the 180 thermo makes do riffernace - (versus a 160) if I'm operating at that temp.

I have had to wire the fans for manual operation for the moment and they are both wired to come on at high speed. CAN'T get the temps below 200 though. Not sure if it represents a "problem" though.

depending upon the car, the additional heat load generated from the forced induction may or may not increase the temps beyond the capacity of your cooling system. You may want to check over in the forced induction section, but there are many blown cars living in much hotter climes than these and their stock radiator and fans are keeping up while into boost. If you simply run a naturally aspirated motor hard you will get the temps to rise, but they should never go over 230°F.

If you have a 180* t-stat, and there's nothing wrong with it, and your gauge is accurate, then your radiator is not up to the job. 205 on the freeway with a 180* t-stat is a big 'ole red flag IMO. Are you running a front mount fan setup, or OEM ?

Just a stock set up for rad and fans but even though I have had the set up on the road for about 3 years, I never noticed the temp. Never bothered to look. Now that I have the FAST computer my (most recent) engine builder says I'm running hotter then I should be but hes a Mustang guy and asked me to check. MOST guys with my combo are running with stock cooloing systems.

My dash gauge is a little over the 1/4 mark ie. about 90 - 92 degrees C for the most part (about 200 F) and the FAST.

Is it a "problem" to be running that hot?

I don't think it's a problem as far as longevity, but in a forced induction setup running hotter just puts you that much closer to detonation. I would worry a little bit if my temps were already at 215* and at that moment had a run in with a worthy opponent. 215* is a pretty warm starting point for a race ? Do you ever get any knock retard under hard acceleration at those temps ? I'd feel better about 180-190* myself.
