Take 2:Roll up, roll up, how much power/torque will it make?

Nice one Andy - great result I would say. Just take your time  s:wink: :wink: s:wink:

Thanks guys.

Yeah I'm really pleased with the result, the performance is just staggering, exactly like a turbo should be.  Its been a fair old drag to get to this, in time, trouble and expense but after this result I can honestly say the turbo route is worth pursuing.  I wasn't so sure prior to it.

Some interesting comments came out of 2nd mapping; Noble reckon the E-manage software isn't that precise, after I swapped the 310 injctors to the 440's and worked out the correction factor the car on boost was running an AFR of 14.9  s:scared: :scared: s:scared: .  So anybody swapping injectors out are wisely advised to re-map before running on boost.  At stage 1 the 310's were the bottleneck though, with the 440's more than enough fuel throughout, no pressure issues and now no wastegate creep, in fact the reverse.  The airflow adjustment has now been zero'd so its just timing and fueling as far as the E-manage is concerned.  Intake temps aren't known as the MAF is pre turbo, but the CC stayed stone cold throughout.  As creep is no longer an issue the wastegate actuator is set to 0.5 bar with the manual boost controller taking it up to 0.87 bar.  On the power runs it pulled to the limiter, 7029rpm curiously, with no problems. Took Noble just 2 hours to achieve this.

I have to say the set-up feels sweet, smooth off boost, starts pulling after 2500rpm with useful urge and at/after 3000rpm the harder you press the gas the more savage the delivery.  In this weather 1st, 2nd and even 3rd on occassion have limited use as the wheels just spin up if pressing the gas pedal past moderately.  I've been short shifting around 5000 as even that feels obscene.  Caution is certainly advised, I'm treading carefully.

the car on boost was running an AFR of 14.9  s:scared: :scared: s:scared: .  .

No problems there, 14.7 is the most efficient.

under boost, you want to be running much richer than 14.7 rog.  s:) s:)
