a very powerful noble !!

[gadgeroonie]

I called in to see west tuning today and chatted over his Noble power conversions

he took me out for a spin in a m12 gto 3.0 with a 5 speed box

it was rather quick to say the least

on a dusty road in second he planted the throttle - the overboost kicked in and it scrabbled for grip trying its hardest to pull sideways - Ray flicked it back in to shape and off we went - I was mightly impressed the car rev very sweetly and made strong power all the way to the red line - i can only imagine it would be a real performer on track.

the power delivery was so smooth the car felt very prediactable and maintained the feel of a standard car.

the mods to this car were very very minimal

one of Rays ecu remaps and an intercooler !!

yes it was on the standard turbo's and made great power - ive never seen 390 bhp from a virtually standard car - My guess is it puts out more power than an m400

a real tribute to Rays mapping capabilities

[gizard]

It was a six speed box and there was no ecu work done at all - it's all been done with actuator work and waste gate / dumpvalve modification.
The ecu's are locked down at the factory

[gadgeroonie]

no this was a 5 speed - Ray can remap them

[m12_nathan]

What difference does the gearbox have to his ability to map it?

If it really was a 5 speed at that power and torque it won't be long before it is back having a 6 speed fitted

[gadgeroonie]

let me re-phrase

this partiular car was a 3.0 5 speed

Ray can remap the stock ecu

Hi,

Can ray re-map the 2.5 Original ECU.

Bondy

[gadgeroonie]

yes he does the 2.5 too

Ray actualy developed some of the boost control for Noble if I remember correctly

whats he done to stop the standerd valve springs not closing proerly causing the the valves to hammer the valve seats oval at the higher boost?

[gadgeroonie]

it doesn't valve float because it doesn't run much boost
only 4 psi more than standard if i'm correct

[adrian w]

whats the standard boost? and whats the m400 boost?

[gadgeroonie]

no idea - someone on here must know

[adrian w]

just remembered that the M400 is 0.85 bar thats about 12.3 psi.

A std 2.5 had 0.77Bar. Matt Faulks says with out going outside the cal of the std ECU it can be set to 0.8Bar, which mine will be when I get it back after 1st the diff going and now the head Gasket (2nd only Noble to have this go apparently).

FWIW, the US 3Rs have a 400hp option (1Bar boost). I can't tell from that graph as it is too small. Is it 390 do the wheels or estimated crank power? My car makes 358 to the wheel, which is 420hp with 15% drivetrain correction. All I have done is shorten the intakes and new intercooler. I'd like to know, as well as everyone else, how much boost he is running. Probably just the factory upgrade

?

What has the boost pressure got to do with how the valves operate?

[gadgeroonie]

its a fly figure

i can't remember the boost vlue but its 4psi over standard

the Dyno this car is tested on is renowned for its accuracy and is not considered optimistic - often named "the ego crusher"

which make of dyno was your noble tested on ?

DynoJet. Which was yours?

[gadgeroonie]

lots of boost and weak valve springs means the valves can effectivley blow open - or float

i have no idea if this is common on boosted nobles

[gadgeroonie]

The Dynojet is well know for its optimistic properties approx 15% - 20%

the Dyno this car was tested on is a Dyno Dynamics

When my engine blew, it was overboosting to 1.5 bar and beyond. Thought the valves were toast, but turned out to be a cracked piston. valves were fine. pressure and flow tested, flawless. They are pretty tough. Dont call me when yours melt tho
