Unbelievable guys you will be snatching the 8 second time slip soon. Hard work dedication and a passion for the twin screw coursing through your vanes. I would like to know what got you there. What was your timing, act temps air fuel ect. And my time slip is not even in the same ball park street car going sideways down the track, ill bet our power level area close though.
I want to share with you guys some success in reducing the temps of the kenne bell case. I had my liquid cooled KB setup like you guys using the engine coolant. I found that my blower got so hot and within minutes that I couldn't even touch it anywhere without burning my fingers and this always disturbed me because before non intercooled version 2.1L seemed it would take a lot to get it that hot like that. The engine coolant being 200 degrees really seems to super heat the blower then with the sc generating its own heat and couple with the exhaust header blasting heat to the side of the case , it's just to hot. I feel kenne bell lacks some direction here in that when they developed this front liquid cooled case they really had the air to water crowd in mind and with that I believe it works fine as long as your not using ice. As far as any application without an alternate source of cooling aside from engine coolant kenne bell kinda half ass says you can route it this way but in my opinion this is a big mistake and only worsens the issue, you would be better of without if plumbed this way.
What I did was use a small engine radiator a small Bosch electric coolant pump mounted in the lower left corner between my radiator and intercooler and then run the overflow line spliced into my current radiator overflow line.
I have it wired to a lighted switch in my dash to a relay to turn the pump on and off if needed. It works like magic and the difference is unbelievable I can run the car all day in the streets stop open the hood and I can lay my full hand on the compressor...yes it's still hot but won't cook your hand. The front cover is a little cooler than the case and when I touch the small radiator its always luke warm. I can only imagine this will translate to longevity of the bearings and seals. I've also noticed the gear oil no longer builds up in my catch can. Must be the lower temps keeps the oil from aerating.
You can see the small engine radiator with cap, it has black plastic honey comb air straightener in front of it. The electric fan from the radiator actually pull air through it.
