Hey Phil.
some tire/wheel questions for ya. You went with an 18, can you help me understand this decision? I'm not sure if I want to go 17 or 18. I thought there was performance ramifications if you went 18 instead of 17? Some people say that 18s are for show 17s are for go, but I'm not sure about the real data behind that. Also does tire selection play a big role in that decision? Especially for a street car I guess.

Now that I own it and I've looked over the BRZ enough I think the FRS front end is the winner for sure. Quote:

If you are going to keep it NA I would say keep the car as light as possible. This means the lightest wheels and the lightest tires. You will be better off with a narrower tire and rim that will allow maximum negative camber. Since the car is pretty light I would even say keep the OEM brakes, just do cooling and brake pads. Now if you are going to build a turbo setup like us, then follow our lead. 18" wheels will give you more room for a huge brake kit and a larger diameter tire increases your contact patch. We also run a radial slick in Porsche Cup sizes which are 18". Most of what I've done was because I had the stuff laying around from the STi race car not really because I thought it was best for an NA BRZ/FRS. |

epic. Thanks for the wonderful advice
I'm just doing bolt ons right now. Headers were just designed on the car this week... hoping to get near 200whp with just bolt ons and a tune. I'm thinking something like 17x8 with 225s, maybe as high as 245s. I really want some enkei nt03m+s in hyper black (fell in love with them when they were on the wall at world one), but the only ones I can seem to find in stock anywhere are 17x7.5 +38. no idea of that would fit or be a compromise, since everyone else seems to be going +45 or so. |

I think +45 is just more common for 17x8. |

Unless you're going to wait for bolt-on supercharger/turbocharger. There's no way this motor will make 250hp with just an intake/exhaust/tune combo. |

I suppose we'll see.
My car is already at 170whp, from 159 starting, with just a downpipe and axleback. I expect intake to add 3-5, and headers to add 10. 183-185 whp... (the car is on the dyno right now). After a tune, who knows, maybe 190-195. From there, some simple things like pulleys, lighter suspension components, etc, and it'll be at around that level. |

Calamity, has anyone ever told you how awesome you are?
here's the dyno results thread: http://www.ft86club.com/forums/showthread.php?t=8755 Sorry for de-railing your thread ET! To get it back on topic: Any potential solutions for the power steering? Remove it all together? |

headers, intake, exhaust, tune, expecting around 23-25whp. hoping for 30.
I'll be updating my thread with the header dyno information as soon as I have it. it's on the dyno right now. (also getting individual power figures for several other parts) ET: I saw you mention in the other thread, that all race cars these days have power steering, so I guess you can't really go without. Hmm. So I guess some sort of aftermarket power steering setup will haveto be used? Sounds complicated. |

You can drive around the power steering issue but you'll give up some lap time. When we get more serious with the car we may have to look into making some sort of cooler.

How does electric power steering even work? Is it still a pump and fluid?

There is no pump and fluid, it's an electric motor in the steering column. Instead of cooling it it might be better to piggyback the steering control unit and reduce the voltage going to the motor. This would increase steering effort but in theory would reduce the amount of heat generated.

In theory it shouldn't require much effort to overcome turning the electric motor unlike a fluid pump on a normal ps rack. So why would I be getting that sensation? I'm guessing to have a quick rack there is very little gear reduction and I'm just fighting the natural tendency for the car to want to go straight while braking with such massively sticky race tires.

Maybe.....just mayyybe they shouldn't have used this electric motor system for the power steering on a car they know people are going to be racing on tracks with. Just sayin!

Besides this particular issue on big race rubber the steering feels spectacular. I'm hoping a simple blower motor directed at the PS motor will do the trick or maybe even an ice pack.

Hey Phil. It's Billy from Freed Engineering. Met you at Hyperfest. Car was looking good sunday on the track.
I dunno if you guys do much welding/fab work but we will have a great exhaust system for turbo/race applications. |

The Gurus at Hydra EMS sniffing CAN data for Hydra EMS implementation. The CAN system is very extensive on the FRS/BRZ but they've cracked everything they need for the CAN integration into the Hydra EMS
Let the wiring begin! Stand-alone EMS integration these days if very involved for plug and play systems. Full CAN integration is the only way to go. We've already found mistakes in a few of the wiring schematics (not uncommon in the early stages). And you thought your stereo wiring was tough. Luckily Hydra EMS is plug and play. Here is a baseline dyno (OEM ECU) we did while dumping CAN data. This was done with 18x9.5 wheels. Dyno operator at ISP mentioned his dyno reads low. Not concerned at the point as I will most likely be doing my work on a Mustang dyno and will baseline again. The Element Hydra EMS is in our FRS so stay tuned! |

I've been running the Hydra EMS in full stand-alone over the last couple days and have spent many hours feeling out this engine. As I suspected the torque dip is primarily due to the intake and exhaust cam timing. You can smooth this out but its hard to say what I'm giving up or gaining until i get it on the dyno. Since i am tuning from zero and not from stock I have still have a long way to go but I'm getting the impression the more I boost low rpm power the more you feel that dip.
Maximizing the power curve on pump gas will be tough but with E85 or race fuel there is lots to be gained but she's knock prone on pump. This is why the oem maps goes really rich at high rpm. We are going to make a push to extract some decent NA power out of this for Ultimate Track Car Challenge. |

really glad to see someone using their BRZ/FRS as a track car. good luck with it and nice talking with you and the crew at njmp.
my local Subaru dealer contacted me Saturday to let me know they received their BRZ it's been running through my mind all weekend but I'm just not sure what I really want to do. when I bought my STi it wasn't like that I knew I wanted it and that was it. once again good luck hope to see you at the track soon. |
