RYU, thanks for your input, I agree with on some of your arguments:
1. An aftercooler would help cooling compressed air down. More hp -> best solution and you do the engine a favor. We're looking into it next winter. It's up to $3000.
2. During my testdrives I measured the hottest areas of the compressor at the pulley and the bearings. The rest of the unit was considerably cooler. Yes, it's friction of the belt and bearings under load. My belt isn't slipping anymore, well during 100 miles yesterday, as I torqued it slightly more (and due to the lower engine compartment temps).
The belt is torqued at it's limit now. I once had it torqued to the amount that the supercharger bearing were making terrifiing noises. No thanks. :wink:
3. Even if I mount an aftercooler the belt, pulley and bearings get still hot (friction).
4. I'm not looking for more hp mainly and cooler intake temps. Only an aftercooler would help here. At the given hp-numbers I'm looking for consistent power and a slipping belt in spirited driving is annoying.
5. An intake scoop is $165 from Downforce. If they could do a similar thing for the right side at below $200, it would be very cost-effective compared to $3000 for an aftercooler, again to avoid a slipping belt and get more consistent power.
I'll do some pics of my temps reading as soon as it stopps raining. Thanks again, I like these (only found on prime) discussions where we look deeper into it.
