BC Racing Time Attack FRS at Ultimate Track Car Challenge Video
Ultimate Track Car Challenge 2015
From Le Mans spec prototypes to classic vintage racers the Ultimate Track Car challenge lets you compete head to head with some of the fastest cars in the USA. This year the Ultimate Track Car Challenge takes place at Virginia International Raceway where BC Racing NA sponsored driver Phil Grabow competes with some of the best in his Scion FRS. Great video by BC Racing and I wish I could have embedded it but the link is worth a watch! https://www.facebook.com/BCRacingNA/...01089733256551 |

Great job Phil. Do you think think there's a sub-2:00 time in the car if you resolve your oiling issue? Seems like you'd be really competitive in the TT2 class if I'm not mistaken.
BTW love watching you drive. Any more in-car video?

Thanks for that.
What sort of power are you at and any figures on downforce? What brake kit? Are there no dry sump kits anywhere for this yet as I noticed the comment about oiling issues still. Car looks very quick. Quote:

I actually have the NASA TT2 lap record at VIR with a 1:58 in this FRS. We had the car way detuned to get through the event in one piece. Transmission and oil pressure are still a problem at higher power levels under racing conditions. Last edited by Element Tuning; 08-14-2015 at 10:54 AM. |

A dry sump will be fitted to this car before it returns to the track so we had the car very detuned for this event (maybe 340 whp in gears 1-4 and a little more in 5th and 6th). The current wing angle delivers about 600 lbs of DF at 100 mph but can exceed 1200 lbs at higher speeds. |

How much have you increased the brake split by?
So do you have a DS kit for sale or is there somewhere it can be bought from? Thanks. Quote:

Tim, the actual split is not likely something we'll publish but I was critical in getting the oem ABS system to be raceable on a car like this. Depending on the kit you buy the split varies but the full front and rear racing kit has the biggest bias change so it's really needed for track setup suspension on slicks and with downforce.
We haven't finished the dry sump yet since most have enough oil pressure with our motor build as is since many of the high power guys don't road race. We've pushed 500 whp at only 19 psi on the dyno to 9k rpm and still had 80 psi of oil pressure. |

Ok yes i understand entirely.
Same here, i log oil pressure and rev over 8k on the road and see absolutely no issue even when launching either. But i'm getting ready to turn it into a track car now so just want a proper sump solution from day one. Was looking at making my own kit but rumours are there will be some on the market soon. Quote:

May I ask, why are you determined to keep the ABS? See my posts on here in the chassis/ braking section regarding ABS modification vs removal. Perhaps you could have some valid input??
I could well be in the market for a dry sump kit for my project. Are the oiling issues here just surge or are they pump related?

Sorry for the late replies as I was out of the country getting a little R&R. Grass Roots Motorsports Magazine released the full lap video of the BC Racing Element Tuning FRS at UTCC VIR.
https://www.facebook.com/grassrootsm...type=2&theater No but it's all custom. A heads up however is that whole wing assembly and mounts would approach $4k. It's a rea1 motorsports dry carbon wing so it's pricey. I'm sure you could make something for about $1k less. Quote:
If I'm going to forgo ABS I'll do it with a pedal box and two brake master cylinders. I'm starting to feel the ABS problem isn't completely brake related and more the entire "Stability Control" system freaking out and turning off the ABS. The system will fault on my car even when no excessive brake force is used but I'm jumping curbs aggressively. I have a OBD module one of the racers from FT86 Factory gave to force "Pedal Dance" and it does that where I could never get pedal dance to work but I'm still able to drive in a way to defeat the pedal dance. The main oiling issue is just pressure/volume related and not oil starvation. Thanks, Phil Grabow Last edited by Element Tuning; 08-21-2015 at 07:22 PM. Reason: my phone spells worse than I do |

Thanks for your great reply there Phil.
I have bought a Tilton bias pedal box with reverse mount under foot master cylinders. Tilton 72-616 is the p/n. I still don't know if I'll keep the ABS, especially after reading what you have written above about it bombing out on track!!
