Will the 180MM Crank Pulley generate too much heat

I think as long as you keep an eye on the cooling side and upgrade, who cares if the pulley is at 60% efficiency and you are dyno'ing 30 more hp as long as you have no heating issues?
Would the concern be longevity?
That is my goal.. I was un-able to note any measurable heat increase by going from the 178mm ASP to the 180mm ASP , based on my data log runs.. My track time did increase though..

The headers I'm looking at are about $2500 for long tubes and with install and follow up tune probably total $3500 or so for about 40-50hp? 180mm and tune would be about $1600 with Xhp? :thinking:
I recall evo saying theri 180 bleed boost and was a no go...
Also how many runs can you do in the summer with that thing?
That power gain is beyond impressive if it’s true, but is this the result of 1 hour cooling car before dyno, then an other hour cooling for that one great run you just cannot replicate every time?
IT has to make the power and it has to hold it
Now is this the case here?
If so have you raced other similar modded cars to see the difference best of 3 just to see if the heating issue comes into play
Thanks!

Also this car i talk about above(04e55) had the ASP 175mm Pulley previously and Active Autowerkes tune and went to the ASP180 and LET tune but we didnt dyno the car with the old 175mm just with the new 180mm. Just between the tunes we gained right at 40rwhp and the top end is AMAZING now.

I meant ET times reduced and MPH increased! Got me on that one
I am not having any heating issues and run in the Texas heat.. The aux. cooler is perfect for this set up.. You can run lap aftter lap and recover in less than 20 seconds.. I ran without the aux cooler for 3 mponths and did not have heating issues but recovery was real slow. Still ran in the 11`s with pulley and 80mm TB only mods.. Aux. cooler really helps,, I would recommend it even on a stock car..
From what I have seen,,, the LET tune is conservative.. They are able to get a very consistent Air fuel ratio over the full hp range and keep it well in the safe range.. It is real power you can feel in the seat of pants, at the track and on the dyno..
