Did some testing today on a 135i, with stage 2 mapping it runs 400bhp/400ftlb. With meth it makes 500ftlb and an extra 40bhp, with a less restrictive inlet (coming soon) we expect peak figures of 500ftlb and 470bhp.
Intake temps down by 30 degrees and EGT's 140 degrees lower.
Not bad for a £200 mod :laugh:

any downsides/risks Dave in your opinion?
PDT:
I have waited and watched loads of kits being fitted to the same engines in the USA, so far no major component or engine failures reported. As long as you have a flow meter to monitor things and pull out boost and timing if meth stops flowing, all seems fine.
h4rdy:
Its hardly a £200 mod is it?
£300 for a decent kit and quite a bit on fitting costs as a lot of trim has to be removed to get the controller in and setup time, say £250.
Oh an you'll need a spacer from INA at £75 to protect the plastic on the TB.
But what a mod, I'm going for it next year.
With V Power your looking at an octane rating of 109?
Like you say cooler intake temps, like driving on a cold winters morning every day.
PDT:
buy the kit from the USA, then its a £200 mod. Its nothing more complex than a high pressure water pump, pulse solenoid and a simple boost vs flow controller.
