Pics of modified stock cooling fans, Optimized for higher RPM use and optimum power Options

All of these units are balanced to Kevin Groots E Production 2.0L SCCA engine. We havewent a little above and beyond to do this so he will have a variety of cooling fans that can be used at various tracks due to the track conditions and configuration.

Each of these will be tested on his engine while it's proving it's self in my new lab in just a couple of weeks in preparation of the 2007 SCCA season, his first with MassIVe power.
During testing we'll be comparing the effectiveness of the cooling fan in both temperature ranges and power potential so kevin will have baselines that he can use to choose the best fan for the particular track event be it qualifying or the mac daddy at the Run Offs....

Each of these will be tested both with and without our newest cooling system addition for the 914 engine, the cooling fan velocity enhancement ring. This ring works with any stock fan on any Type 4 fan housing as a bolt on component. It protrudes into the fan inlet and helps to boost the speed of the air entering the fan as well as helping to direct that air into the fan more effectively. The unit pictured is an R&D unit made for me by good ole "spunone" who has become our go to guy for trick test components like this! Thanks man!

I'll be posting data logs from the testing over on my forums in the "Dyno room" section in a couple of weeks..

BTW- I invested in 4 more pressure transducers for the new dyno lab today. With these we'll be able to log the pressure inside the plenums of the cooling system with each fan running the same pre-programmed sweeps and track simulation tests for exactly the same amount of time..

These can be plotted on the trace chart and analyzed Vs HP, RPM and head temps.... With this data there is nothing that we can't figure out about how fans and temps behave... We also have two fan housings to test as well, a modified vanagon shroud and a stock 914 shroud...

The nice part is the fact that we can use two of the transducers to measure plenum pressure and the other two to measure the pulse rate of the air (if any) with some fans... There is a reason why I spent 3,500 hours creating this lab.
