2013 Boss 302R build thread(PIC HEAVY)

The time has come! April 11th is the shake down for the car at Homestead Miami Speedway. Picked it up, had to redo the exhaust due to regulations for NASA giving a penalty if it’s dumps. Had a 3 inch exhaust installed all the way back and having some Toyo RRs slapped on. Will post pics/go pro footage after the event

What a journey! Looks amazing and I can't wait to see the on track footage!

After 5 years, 2 months, and 17 days.......the time came. First track day was last weekend at Homestead Miami Speedway!

First session was great, was starting out slow to get a feel for the car and see how it reacted. Fuel pressure stayed at 55 PSI thanks to all 4 bosch pumps firing away in the ATL fuel system, oil pressure nominal, and most importantly...car runs like a bat out of hell. Was pulling some serious G's in the corners and braking zones once the pads warmed up with 0 brake fade thanks to some Motul 660 RBF and Gloc R18/R12 combo.

Second session was a bust. coming out of the pits i encountered some serious chugging and could not go above 3k RPM. limped it back to pits and encountered fuel contamination from aging foam inside the fuel cell. Made an emergency tear down, siphoning out the old fuel and cycling the pumps to empty the reservoirs. Emptied the foam out, cleaned the bladder and resealed with new fuel. Purged fuel lines up to the rails and voila!

Third session went excellent, kept pushing the car now further and further. no oversteer, very very minimal understeer and the car feels planted down to the ground thanks to a couple of adjustments with the splitter. Going into turn 8 had a lockout from a 4-3 downshift, attempted to put back into any gear and i was completely dead in the water. waited in a run off 30 seconds or so, put the car finally back into gear and limped it off to the pits to inspect. Shifter had significant slop but it seemed that the car was shifting as it should of. Our guess is that the fluid going to the slave cylinder boiled and prevented the clutch from fully disengaging. Was remedied with bleeding the slave and wrapping the clutch line in gold foil heat shielding to prevent further instances.

Fourth session was beautiful. After over 5 years, the car finally was not only on track but singing its 7500 RPM songs without interruption or flaw. Once i got into my rhythm i was cutting 1:45's consistently and i still feel the car has ALOT left in it once it is properly tuned and a fresh set of tires are put on (Toyo scrubs were being used).

Amazing journey!!

Update, going to homestead Miami speedway again September 5th to finish dialing the car in.

Cleaning up a lot of wiring, installed the Peterson catch can, gold foil around the intake, relocated battery, fixed GoPro, rerouting brake ducts, and switched to a Barton shifter. Will post more pics but here’s the gist of it

That gold tape doesn't do squat

That's actually not true. It dropped my IATs 18-22 degrees on my Gen IV ACR. I had a heat shield around the intake, and I wrapped the outside of it.

When we install the box it will. Also, we are wrapping the bottom of the manifold with it. We tested it on another car with a similar configuration and it worked miracles with IATs

Can't believe I missed this thread for five years. This is the best build thread I think I've seen! Congrats on sticking it through to the end and reaping the rewards of your hard work! Awesome job!

I wrapped my aftermarket TMIC on my WRX which is mounted right above my turbo with DEI reflect-a-gold and even during 90 degree hot and humid days you could always touch the intercooler with your hand. I'm saying it was cold, but you could always touch it and never once did I ever burn my hand or have to quickly pull away because it felt way too hot. The stuff is pricey, but it definitely works as advertised.

While preparing for this weekends race, we decided to do brake ducts...but it seemed that the present options were either too small (2-2.5") or too expensive for a 3"+ setup. So after some google engineering, we purchased a 4 to 3 inch PVC reducer, made some modifications, got some raw hose from Hoerr Racing Products, and found a set of backing plates on craigslist off a super snake for around $45. The reducers, plates, and hose in total came to approximately $135 shipped for a full 3" duct setup with minimal effort needed to make it work.



Took it back out to Homestead Miami Speedway this weekend to run it through its paces. the Toyo RR's while great are shot at this point and the shift linkage seems to be giving us some issues which we will need to work out, but overall we had a great weekend and even after dive bombing the corners there were no signs of brake fade.

What pads are you running?

 

[13COBRA]

Those Corvettes at 3:25 were wanting to pass a race Mustang haha

 

[GCubersoldat]

What pads are you running?

Gloc R18 race pads for the front and R12s for the rear. Very aggressive pad but once you warm them up they’re one of the best out there. Just need to make sure you clean the wheels after each weekend because the brake dust is corrosive.

You might consider ST47s when you are done with those. Seems like everyone has moved to them. I just did and so far they are great. They last a full race season.

A whole year?!
