TonyF had his car on the Dyno recently - he asked me to post up the results

it was not making the proper power you would expect from a M400 - a good one makes approx 380 bhp

he went from 343 to 375 (370 lb/ft of torque) with a fuel pump and a good set up at Gary's !!

Tony - how does the car feel now ?

didnt he notice how slow it was before? A 3R would have walked all over him.

Mike, car is still hesitant at the top end I presume it requires a mapping session at garys soon ?

Adrian, this is my 1st experience with a noble so nothing to compare it with really.

I presume that is at the wheel figures?

Given it's a dynodynamics in shootout mode I am pretty sure the answer is yes.

I know you can't directly compare different dynos, but given mine was 409bhp standard on a respected company's dyno, and 436 after a 'good' setup by Roush (admittedly with their exhaust system), could there could still be something rather wrong with that car?

At the wheel figure was 305.8 bhp, the car does feel a bit hesitant at the top end on acceleration though! Mike says that these figures are about bang on for a standard M400. Obviously my next visit to garys will be for a good mapping session.

Can I suggest you talk to Roush instead. That doesn't sound "normal" at all.

Remember mine made 355 at the wheel (dotted green line) after 10000 miles, normal servicing, no changes.



Being over 50bhp down on that cannot be normal, whatever anyone says.

The Roush exhaust (again, no mapping changes) changed that to 385 at the wheel.

Joust - being from the Dyno industry I can tell you that there are some rather optimisitc Dyno's out there

I suggest you get you car tested elsewhere to compare your figures

shootout mode means the results can not be interfered with by the operator and the car will make exactly the same power every time on every Dyno

380 bhp is about what an average m400 makes - maybe the factory have been sending them out on lower power for some reason ?

Mike the rolling road/dyno that Justin's car was tested on is reliable and proven accurate and reads about 3% behind Garys. As far as Tony's car is concerned i'd be doing a compression test.

I know this arguments been done to death but I reckon Gageroonie is spot on. My M400 was 370 'ish - optimistically!

Maybe Joust's car was a one off given his 'special' relationship with the factory!or maybe the later deliveries were 'detuned' for some reason!
