11/9/05 - Final Tune - Fuel pressure was perfect at 56psi. The car made best power at 24 degrees of timing. HP is now at 398 and 410 TQ:
2/18/06 - Switched to 3.90 gears from 4.10's, and adjusted kaaz differential from 100% lockup to 33%. Diagram showing how to set up the Kaaz
1/28/07 - Johann installed custom power steering system and a new exhaust turndown/tip.
4/7/07 - Installed stock gas tank, Hyperion's Surge Bucket Cover, fuel pressure gauge. Click here.
7/1/07 The HINSON power steering kit comes with rubber high pressure hose but HINSON sent me one made of braided stainless steel, which I wrapped with a ceramic heat shielding (Thermo-Tec Thermo-Sleeve Insulation) because how close it is to the headers:
10/30/07 Evans high flow water pump & 5.25" pulley (smallest pulley = highest flow):
Water pump installed:
Hinson radiator and fan (on right). The taurus fan (on left) will not fit with the bigger Evans water pump.

Stock crank pulley is 7.5"
10% UD is 6.75

I think my water pump pulley is 5.4 inches diameter (17 " circumference).
