What did you do to your Supra today?

[Thraxbert]

I need details! Looks awesome, can you explain what all it does and who installed?

This is the Precision Raceworks AFS.800. The system has two Walbro 535 pumps in the tank, plus the OEM pump. The OEM pump only feeds the DI system, and the two Walbros only feed the PI system. It's a "regulated" system, meaning the fuel pressure is adjustable to hold a very specific value, then increase as more boost pressure is applied. In other words: the PI system turns on when I start the car, and any unused fuel just goes back to the gas tank.

Advantage to this setup, versus something like PFS or Vader, is that that this system does not fight with the OEM fuel controller to set the right fuel pressure. This is especially valuable under WOT, where the PI and DI system (often) need constant correction because the OEM pump is trying to pull back pressure, but the aux pump(s) are trying to add pressure. Any system with a dedicated feed to the PI system should work this way, but I chose the PRW kit for this reason. It makes tuning easier, fueling easier, AFRs safer. All things I wanted. W

The craftsmanship is excellent, the wiring harness is excellent. Personally, I think this should be the go-to solution for most people considering PI. There's also a AFS.460 model with a single extra pump, which would be sufficient for most people. Overall, I'm really impressed, and with three pumps this is my "lifetime setup", which I was also interested in. Buy once, cry once.

Personally, I think this product is also a good deal. I don't mean "inexpensive," just a good deal. Considering extra fuel pumps are already $600+ for DIY kits, or $1000+ for true PnP options, a little extra to get the "best" made sense to me. Custom-made electrical connectors, billet components, no half-assed shit, clean wiring.

Edit: for any tuner who stops by this, we had the best results setting the FPR to 43.5 PSI. It's 1:1 boost referenced. We used solid state relays. We disabled the relay trigger in MHD+, kept the <40 PSI soft limp mode as protection, and then just set PI to trigger @ startup with no throttle input. PI pump is at 30% DC.

I love reading your stories. ???

agree. DO NOT WRAP A CF BODY!
Where do we sign the petition????

i guess renting an entire track is what rich rich people do????

Back to topic:

I will get the license and the laptop. If I succeed on shutting down the Christmas tree and you meet us there we can code them out then.

CF, 21st century chrome in a lot of cases. Quietly knowing it's there and being low key about it is the way for me, not making it an in your face feature.

Replaced my pads and rotors. My hawk DTC60s were overheating and I kept losing brake feel. When I removed the pads they had very little life left and were cracking.

Replaced the pads with Carbotech XP12s hoping that they will work better for the long hot sessions I will do in summer

Also found GiroDiscs at FCP so jumped on them.

Lifetime replacement, nice! Probably lighter than my cheapo RockAuto.com ones too. Hope they do the trick for ya. Do they make them non slotted?

I found after using slotted and/or drilled rotors I‘d go thru pads much quicker and didn’t stop any better. So I up’ed the pad compound to project mu 999 and/or CSG (CE2 or C21) and added brake ducts.

This last weekend the CSGs were doing really well but I ran out of track time to really comparatively test them against the P mu999s.

I'm still newish to tracking, less than 1 year though I have 17 track days already. Did spend several 110+ track days at thunderhill so I think I'll need cooling to make sure I do stop while I still learn to not overbrake.

The girodiscs I don't believe are made non-slotted. FCP also has regular rotors, the rears I got were these https://www.fcpeuro.com/products/bmw-brake-disc-zimmermann-34216860925

Realized I didn't share the link for those who would also want to jump in on this "deal" https://www.fcpeuro.com/products/bmw-disc-brake-rotor-set-girodisc-a1-307

I'm making it a point to try to get as much as I can from FCP for the lifetime replacement aspect. Although, it's only worth it if you have access to very cheap shipping.

grocery store run

Finally got new front rotors. Decided to go the affordable way because… well, is affordable and have been advised against bad quality big, drilled, or slotted rotors.

(Two brake shop guys tested my car and told me that my OEM rotors were warped. Not sure how I did that)

Got them Bedded in, will bed in some more tonight when both other cars and cops are not around watching me doing what otherwise looks like crazy stuff.

got it tinted today

“Mom, I think this guy in the Supra is trying to race our mini van. He keeps on getting on and off the gas like a maniac trying to intimidate us”.

Finally got my wheels powder coated and mounted. Installing MSS Springs probably next weekend. Barrel/Lip is Brushed Bronze, face is Matte Golden Bronze.

Going with a 90's Black Panther comic book theme lol.

~ looking great ... the lowering springs will pull it all together for the complete transformation!

I got my DME back from Femto today and after I plugged her back in and started the car, she coughed and spluttered before flat out refusing to start! After a brief moment of panic, I decided to unplug the battery and carefully re-seat the DME connectors. She then started up with a roar. I took her for a quick test drive and was all good. #thankfuck.

I didn't have any issues, but I have heard of some folks doing just this. Didn't seat the connectors all the way. I know I would have shit my pants, if this happened to me. Right there in the driveway. With the neighbors watering their grass. In broad daylight.

Those DME connectors are a pain in the dick. Who designs a connector with a positive lock that can click when it's not locked? Oi.
