Hello.

Which cooling-kit or package do you guys recommend these days? Does VRP offer cooling-kit? LET?

Any information is welcome!

Thanks.

 

Let h/e and cm30 pump you are good to go.

 

my floored fab kit has served me well!

 

I have got the EvoSport cooling kit and I am more than pleased. I also have one of Patrick Eves' 180 degree T-stats in my car - I think 'stock' is 190.

I didn't choose Evo necessarily 'over' any of the other tuner's kits. They just weren't quite available when I ordered mine. Since that time, Victor (VRP)has put together a turn-key kit with all installation hardware and directions as has RennTech. I am sure than any of the major tuner's kits are reliable and use high quality parts.

I will say, it looks to me like VRP uses a larger secondary heat exchanger than my Evo kit does which would carry more coolant in that circuit and displace more heat.

I will say that I can drive my car very 'enthusiastically' so to speak and when I pull into my garage, I can pop the hood and literally lay my hand on the surge tanks and the top of the SC with no discomfort. It's definitely warm, but not 'hot.' If i turn my car off and wait 15-20 minutes for the inevitable heatsoak to occur, then the top of the SC is off-limits hot, like as in 'don't touch it or it'll burn ya' hot.

In other words, the Evo kit does a great job as long as everything is circulating and wind is moving past the secondary heat exchanger. Turn everything off, and it heats up quick. So, maybe the real measure of 'effectiveness' of the various kits out there is to drive hard, park your car for 20 minutes, then fire it back up and see how long it takes for intake temps to drop into the "good hp" range.

One thought I have had and maybe some forum members can address it is the theory of splitting the engine / SC coolant circuits. Mine are of course separated due to my Evo kit. However, it doesn't look to me as though there is a whole lotta' coolant in that SC circuit as compared to the engine circuit and primary radiator. Provided you have added a larger heat exchanger for the SC, upgraded to a more reliable and higher flowing pump, and maybe even went with a cooler T-stat, does it make any sense NOT to split the circuits in order to work with a higher volume of coolant passing through the SC? Maybe the higher temp of the engine coolant to begin with is the answer to that question. Any anecdotal advice appreciated!

 

yes the one flaw is if you arent moving it gets hot. sucks for at the track.

 

I have the Code 3 with the Johnson CM30 and love it.

 

Code3, LET, VRP, evosport, etc...
90% of ppl choose Code3 and LET because of price...

 

Ding Ding. You bring up a great point. Larger reservoir would be a great addition (and why many are going to the remote mounted one) but separating the systems isolates heat better and gives lower IAT spikes. Our cars still spike even with the cooling mods, so lowering the baseline temp keeps the spikes lower too.

BTW, the EVOsport is a solid kit. I have seen a number of cars running very strong with their cooling kit.
