The AN braided lines switch to aluminum tubing under the car, to protect them from fire / cutting / off road adventures. The feed line is a -8 and the return is -6.



Most of the fuel system is completed when I write this in January, with just a few items left to plumb this week.



One of the craziest parts of the fuel system is this Injector Dynamics F750 fuel filter with optional pressure and temperature sender. It has pressure differential meter on board, drain, integral mount, it is all made from 100% CNC machined aluminum. The point that really matters: it has a replaceable filter element.



This was something G-SPEED insisted on for use with the Motec and cost a staggering $550. For a fuel filter. But these sensors are what they wanted for pressure and temp signals, so on it went. When you see it fist hand, the fitted foam box and the jewel like fit and finish, you can see where the cost comes in.

HYDRAULIC PARKING BRAKE INSTALLED

The OEM rear disc brakes on most modern cars use an integral drum brake inside the "hat" of the 1-piece cast iron rotor. The drum is actuated by the parking brake lever and locks the wheel when parked.



Well the Powerbrake 350mm 4piston rear brake uses a 2-piece rotor with an aluminum hat. Like the Stoptech Trophy and almost all other Motorsports brake kits they do not have a provision for a parking brake. But for Optima use this car needs one. We did some research...



We found that obp Motorsport out of the UK makes a hydraulic, stand-alone parking brake handle, mostly used in the drifting world. These also have a lockable setting for use as a hydraulic parking brake. I ordered the one Ryan spec'd and ... they shipped the wrong style, above, which is made for drifting. So now I own that one.



I re-ordered the same part number and the second time they sent the right style, which can be configured to allow the handle to lie flat - like the stock unit. Stop the car, pull up the handle, engage the lock, and you have locked the rear brakes for parking.



Ryan built a bracket, mounted the E46 "console delete" center console, built a cover for the cup holders, and it covers the obp handle nicely. We will show the plumbing of this in a future post.

1-7/8" LONG TUBE HEADERS COMPLETED

These custom headers should have been done months earlier but we had a series of delays on parts, tools, and equipment that is too long to list.



After the ICE Engine Works 1-7/8" header modeling kit arrived in November and then the Argon flow meter regulator arrived in December the last few bends could be finished.
