Stock vs MHD V10 vs Hybrid turbos

[B21]

I’ve now completed my odyssey of stock 35is through MHD V10 to hybrid turbos with German TTE500 turbos.

I overlaid the best off for stock..MHD V10 stage 2+ and the TTE500s on the same graphs do it’s easier to assimilate the differences…

The stock figure at 347 is better than the book figure of 335 for a 50k mile car with walnut decoke and fresh plugs n filter..so a good basis

The MHD V10 reflects the tuners work on a 12 year old conservative tune by BMW

Our tune with TTE500s shows the results of the best off in terms of products and a steady set of tuning developments over several runs.

The graphs reflect how it feels..

Smooth and slightly better off the line..powerful low range shove, turbine feel through the mid range and a rocket like unceasing charge to the red line..

So apart from cost no downsides…smoother, more powerful, better high end performance….good result — feeling delighted.
