My BRZ: White Lighten-ing, and a formal Introduction

Recommended Posts

Joe; a note about bare stainless steel lines. Don't let them touch anything but thick rubber.  I like your grommet hole. But also I recommend putting a little rubber in between the lines as they pass through that hole. I've seen over time some really unfortunate leaks from time and rubbing. These are worse since it has fuel.  When I'm doing jobs I'll always keep one or two old radiator hoses in tool storage so I can cut them up for custom rubber "spacers".

Thanks for the tip! Inwas wondering about that already actually. I'll make some rubber sleeves tonight. I have a couple of sheets of rubber I can cut up and use that will suffice until i can find a permanent solution!

When I do this on oil lines I just put a cut coolant hose halfway on one line and zip tie the two lines together making a rubber "jelly" sandwich between stainless steel lines. You'll be a little more creative with 3 hoses in mix; but it doesn't have to be a lot of rubber in between them if you control where they touch with zip ties.

Surge tank FOR THE WIN! ALLZ THE WINS!! Was able to run the car at pace, all the way down to nothing. I intentionally went full tilt boogie for 2 laps after the gas light came on. Not a burble. Not a hiccup. No loss of power coming out of carousel (left hand continuous turns are what would cause the starvation below a half tank).

Also- I lost one of my super sweet Texas flag endplates...not sure where, but after coming in from a session Saturday, someone noted that my car looked funny with only one of them ;) My "bargain deal" used carbon wing came to me with loose endplate threaded inserts which I had tried (in vain apparently) to re-epoxy down twice. Turns out, they could no longer contain the majesty of the lone star banner as it broke it's epoxy chains once again - flying free into the wild. My guess is carousel or coming into diamond's edge.

It will be replaced with a Nine Lives aluminum job. The broken carbon wing had already been traded away to @clifton23 and his Champ car team for the promise of multiple future beers and a cheezy-burger. May it live again to help keep their MR2 planted !

Coolshirt also worked flawlessly. The decrease in fatigure is what amazed me - I don't think it was placebo effect. I am unsure how I did this through 2 Texas summers without one. Never again!

x2, and the trifecta is after they're rubber wrapped, to zip tie them together so there's no movement.

Yeah, I went through and hose-wrap-sandwiched them at all contact points, with zipties at each point for motion restraint. I am now wondering if rubber pushlock type hose with Pushlock to -AN fittings would have been a better choice. Put some abrasion resistant sleeving on it, then rubber sandwich them?

This might be a good braided stainless line vs rubber pushlock type line discussion in tech talk. We're talking all low pressure here, the highest anything is seeing is 45 psi. I may need some schoolin' here...

Coolshirt

I was kinda "meh" about one until I tried it. I figured I'm only driving 20 minutes at a time, so no need. But they really are magical. I have a proper fire suit now as well, so it will be even more important. I need to finish rewiring mine to get it back in service before the June TDE at Cresson.

Stainless I believe has more protection than the other type. They do actually make stainless with a Teflon outer coat; but I've only seen them on small brake lines and there is a price hike.

Made some progress. Since I'm abandoning the chassis mount for the wing, I have room for the cool shirt cooler to live permanently, so I made that setup, painting the spars red. Why not a splash of color...and I was out of black Krylon 😉

I also grabbed an intact trunk lid, which got the Krylon touch, and some racing required decoration...

Wiring harnesses made for the coolshirt setup and transponder. Cool looking top-gun-esque switches used because I had them laying around, and honestly I'm too lazy to dig around the wiring digram right now to find the ignition signal wire to use to trigger a relay lol...

As soon as the new wing setup arrives, we're in business again! Oh, and I build a bulkhead to separate the surge tank from the cabin...and change up how I am running the lines. And make a fuel pump basket cover. And replace my front lower control arm spherical bearings. And....and....and....Haley says If i say "the racecar is almost done though" one more time shes going to stab me lol

Poignant failure experienced by a buddy @CodeMonkey  at Road Atlanta last weekend drives your point home! An unshielded oil cooler line that rubbed through is pictured here... found post mortem 😞Doused the track with 5W-30, and killed his motor in the span of seconds. 

Definitely going to rethink / perfect my fuel line setup now.

I know how bad that must suck. Man engine lost ☹️  .  I found out about this when someone had a brake line saw a control arm in half and crashed from lose of control.

Yikes- Sad to hear a motor bites the dust. 

My car is at the shop.  Thus; while up on the lift tomorrow oil cooler lines (and others) will be on inspection/preventative tasks.  Thanks for sharing the information and making me go p (Preventative).  ;0
