Added Pure900 and Pure650 to the first post list.

I was told by someone who works at Pure that the 900 is a 65/62.

Updated TTE turbo info with turbine wheel size.

You are correct. It is the same as the 850, just with larger housings.

Thanks guys, updated the list!

Turbo: Drift Motion stage 3.

other mods: catted dp, charge pipe, intake, pi with Wagner mani and 980cc injectors, pfs lpfp, meth injection, e45, and Reflex +.

Currently remote tuning with Fabian at Pureboost. I will Dyno when complete.

For shits and giggles I uploaded logs into ChatGPT and asked it to provide a graph for tq and hp, results were 622hp and 559tq.

Try using openai o1. This model has multi-step math reasoning.

If ChatGPT is referencing torque in the datalog to create the chart, it will be most likely be off as the torque Nm in the log is usually skewed by the model in the DME as you tune. It also doesn't take into account weight, tire diameter and drag.

For reference I put a log through ChatGPT and also through vdyno software which creates power charts from speed data instead and use tire diameter, weight and drag inputs. From my experience using vdyno and a real dyno, vdyno can be very accurate as long as you use a flat road and set it up correctly.

You can see here that the ChatGPT chart is wildly optimistic because it is using the Torque Nm in the log to create the plot.

What tuning software are you using?

What tuning software are you using?

I’m using MHD.

That’s the one issue I had in the back of my mind with it using the torque reported in MHD. It is smart enough, after I told it, to convert the NM to Lb-Ft. I fun messing with the ai and trying to get it to understand my questions and reforming my questions so it can understand what I want. I will ask it to take into account vehicle weight and tire diameter.

I’ll see what Bruno has to say too.

I saw that the Turbosystems turbo is not on the list yet.
https://www.turbosystems.info/produ...for-supra-mk5-bmw-z4-g29-upgrade-turbocharger

I have confirmedthe compressor and turbine sizes for both inducer and exducer on stage 1 and stage2


Stage 1. 550+ hp rated. CW 57/71mm TW 53/60mm

Stage 2. 700+ hp rated. CW 62/77mm TW 55/60mm

53/60 and 55/60? Sounds like a huge recipe for lag.

or are you saying it’s 57/60 and 62/60? Inducer/exducer

It's
Stage 1. 550+ hp rated. Compressor 57mm induce, 71mm exducer. Turbine 53mm exducer, 60mm inducer

Stage 2. 700+ hp rated. Compressor 62mm inducer, 77mm exducer. Turbine 55mm exducer, 60mm inducer.
Both are 9 blade compressor and 9 blade turbines.
Stage 2 is about the same as TTE6xx
