    Re: Aftermarket Cooling system

    Naf is in Kuwait, so I'm sure he could use a bit of extra cooling.

    I seem to recall that one of the tuner V's had a Ron Davis radiator (http://www.rondavisradiators.com) They don't list the CTS(v) as a supported OEM replacement kit. It might be worth contacting them, to see if they've already done one. I bet it would be fairly pricy.

    Naf, If you do get one made, you should try and get one with an integrated Power steering cooler, and possibly oil or tranny cooler as well. Bonus points if it is about 2" lower than stock, to allow for an Over The radiator Cold Air Intake (OTR-CAI).

    Good luck,

    Chris

    Re: Aftermarket Cooling system

    There is a part number for a "High Capacity Radiator Kit". However my parts guy said he could not get ahold of it. The number is PN 25534465 High Capacity Radiator Kit. You might be able to call the same guy at GM that Feffman called and got the engine oil cooler kit from in this thread Feffman's engine oil cooler from GM Racing

    Re: Aftermarket Cooling system

    I checked with Ron Davis last year when my V was in the shop for a leaking factory radiator. The dealer could not get one at that time for 2 months!

    Anyhow, Ron Davis would build one for $1600, which was with no coolers for oil or trans.

    I'm sure the price would still be about the same.

    Re: Aftermarket Cooling system

    I had one made by BeCool. It’s a worth while investment. With the RPM's and boost levels I achieve on the track I had no choice. The stock RAD couldn't handle it.

    The cost was about $1500.00. They replicated the stock mounting points and upper and lower rad hose outlets so it just bolted in.

    Re: Aftermarket Cooling system

    in 90* weather my coolant temps were in the 220-240's which aint bad......oil temp was high around 260-280.....but stock rad seemed to handle the water just fine.

    Re: Aftermarket Cooling system

    Now that Nels has so kindly paid the "set up fee" I guess I could try calling Mitch at BeCool and see if he'll do a Group Buy for us.

    He did a long term buy for my Impala brothers a couple years ago and still honors it. Built in oil and tranny cooler. Real nice piece. Lowered my twin turbo 383 stroker operating temps by 15-20 dF.

    BeCool is the shiznits.

    I beg to differ. If you're really pushing the car to the limits (really) then you'll need all cooling systems like oil, tranny/diff, steering and a bigger/better rad.

    Most of us think we can push our cars to the limits but in reality we push them for "our limits"...

    Put a pro driver in your car and you'll have everything overheating within 4-5 laps.
