Due to my very poor results in the 1/4 mile when doing testing for SCC (12.8@ 118 mph) I have gone back to the drawing board to try to figure out whats wrong with project Z. I was figuring that the more open nose of the JDM front end was causing air to blow sideways accross the filters of my JWT Twin POP disrupting the MAF reading at high speeds causing the car to nose over and run dead rich. I could feel the power sag at over 90 mph. So I had my friend Leonard Carson of LDI Carbon build a carbon fiber airbox that shields the Twin POP from errant breezes and water. This airbox also stops the stalling you get when you push in the clutch of a POP equipped car while moving. With my airbox, you can remove the plastic shield that blocks the radiator air entirely for better cooling as well. I also reduced my water jet size down to 0.7mm jets and advanced my timing from my previous conservative 13 degrees to 16 degrees. The results, 574.2 hp and 549.1 ft/lbs of torque to the wheels at 24 psi, up from my preivous best of 560 hp and 547 ft/lbs of torque. I am getting pretty close to Zoe for peak hp with a lot more torque and a broader powerband. I am pretty happy with the 14 hp gain just from some simple tweaks! The funny thing is I had to dyno because its so hard to tell seat of the pants if your tuning is actualy helping because a little more of oh god fast is hard to tell from just oh god fast! Next step, more efficent ball bearing turbos, more boost and new cams. 600 wheel hp here I come! I am confident that the Airbox will stop the top end layover that the car was experiancing and my mph will now be in the high 120 mph range like it should be. If someone wants to scan and post my dyno sheet, send me the fax number and I'll fax it tomarrow. Mike
