As some of you might know, our Z Car Garage and CityTech Auto Body Sponsored 350z has been through a lot of struggling with overheating problems after we installed the a Vortech Supercharged Kit. We have spent tons of time and testing to make it cool down. Our goal is to make it last through the whole 20mins session without worrying about overheating with full power.
07/20/2013 Saturday: The first practice day of the Redline Time Attack event was at 102F, a perfect day to put a ultimate heat test to our new setup. Compared to our last event which the Z lasted only 2 laps before overheating, we installed a 2nd oil cooler, running 50/50 Methanol water injection and de-tuned. Also, Rob suggested that to remove the aftermarket electric fans and put back the stock fan with shrouds. With all the help from our crew and Z Car Garage, we double checked all the fluid levels are full, adjusted tire pressure and started our first 20mins session. The Z felt great with the supercharged power on the first lap, pulling on every gears to the redline. But will it last full 20 mins without a drop of power? 4th lap passed by, our Nitto NT-01 tires started to get greasy due to the heat, but Oil temperature still stayed at 230F, intake and water temp stay cool without a sign of overheating, no power dropped. We are so amazed because our last event only last 1 ½ lap before oil temp reached 290F. We managed finished with the best lap time of 1’58.8 running CW13 configuration.
Special shout out to Z Car garage crews for their awesome work keeping the Z at operating temperature while making great power in this extreme operating environment.
The next event will be at AutoClub Speedway, Fontana on Sep 15, 2013. We will be doing some more modifications and possibly installing a full roll cage on the Z. We will keep you guys updated.
