AZRR CYM FD Build Coming Together

I agree with Cosmo. I cut a bunch of small squares into my stock undertray and noticed a difference in temps both on track but particularly in stop/go traffic.

In stop/go traffic, the vents in the undertray it resulted in a small difference in cooling temps (~1 degree C) but a slightly bigger difference in air temps and related to heat soak.

Also, I recommend using some of these hose clamps on the silicon coolant hoses:

I had tried using some expensive, high quality, worm type hose clamps and they would loosen over a few heat cycles. These Breeze constant torque clamps work incredibly well and never loosen up.

Thanks for the real-world feedback both on the undertray and clamps. I may switch to something like the clamps you're specifying. Had my first real-world driving experience yesterday when I took the car on her maiden voyage to our club picnic (30 miles round trip). All went well and temps were extremely cool, especially given the fact that I was running without the undertray. Temps can only get better once I get that completed and installed.

Just added a new fuel pump last night (Bosch 044) in place of my Walbro. The Walbro was working OK, albiet my fuel pressure regulator needle would oscillate 2-3 psi while the car was running.

Fuel pressure is now ROCK solid. Wow, that Bosch unit looks like your stuffing a little beer can in your fuel tank, but man, can that sucker pump! Now, once we get her broken in we shouldn't have any fuel starvation issues

Just wish I would have taken a pic of the pump before install so you guys could see the size difference!

Thanks Cosmo. Yup, that's it. Dwarfs the Walbro.
