Race Tracking Your Supra - Information exchange

I think I got my use out of these.

Also did an oil change, added magnetic drain plug, put 2 piece rotors on, changed pads, nut and bolt check, fresh brake fluid….. Just about ready for Laguna seca in 2 weeks.

I'll be there! I'm in intermediate group -- it'll be my first time running the track.

The drivability of OTS tunes leaves a lot to be desired. It’s still perfectly serviceable but I was slipping on low pedal positions. Custom will give safer and smoother power in general with a good tuner. If you’re adding an hpfp and injectors then that’s territory where you definitely would want a tuner.

Don't the new MHD tunes have an option for linear throttle? Looking at doing this and then digging into Razors self tuning guides to clean it up if needed.

Come pit with us. Will be with another Supra with me already. Bringing the RV so we will have plenty of space for you. You are going to love the track. This will be my 3rd time going. I will be there Friday night to Sunday if you want to link up.

The OTS tune is locked down so you can't take an OTS tune and modify it. Yes a custom tune can have the pedal torque request table adjusted. My custom tune has a pedal that drives like OEM non-sport mode and I love it. Super easy first 1/3 of the pedal. I find that I can modulate the pedal better once I'm already in it. I don't want it requesting max torque in the first bit of throttle position.

I believe on other platforms, the MHD OTS maps have different pedal curves to choose from. But not the case with b58.

Yep this is what I was referencing. Thanks for clarifying.

What's the hot tire this year? B-stone? Nakang? Yokohama?

Bridgestone IMO.

I've ran the new RZ against the A052 and generally prefer the RZ. The Yok is fine in cooler temps, or for a single flying lap. For most other scenarios the RZ is better, and now comes in a lot more sizes than the RS. The wear on the RZ is also pretty awesome with several people I know running them to the cords with very little drop off in grip.

Guys, I'm thinking about upgrading power to ~530-550whp (630-650hp crank) range, running custom turbo simmilar in size and capability to pure800.

Would E30-E32 on flex be enough E for track? I'm mainly concerned about stability, safety, logs, coz for the power goal should be enough. Wondering if e30 is good enough or it should be bumped to e40 or no reason at this power level. Dont want to stress it/blow it coz of the fueling.
Any advices?

Livery update (still all my own design), official Yokohama Poland car now, running A052

Given the stock turbo on E40-E50 can hit 500 whp, a much improved turbo like Pure800 sized "should" hit those power figures without E blends. I'm not as familiar with what the stock fuel system can handle on regular pump gas after turbo swaps though.

Reading your post it sounds like you're more concerned about temps or otherwise vs injector duty cycle. I would say as long as you're monitoring IAT and other general temps running E is not much different than regular gas. There is a cooling effect, and higher octane rating, but if you're not pushing the car hard power wise they don't come into play as much. I would only switch to an ethanol blend if I were chasing more power on a given turbo setup vs just for reliability.
