Late last year, I had some pretty severe issues which resulted in a new engine, and many thanks to Noble London, Giles, and Lee. Details on this thread:
www.pistonheads.com/gassing/topic.asp?t=337059&f=26&h=0&hw=lee+giles

Anyway, the good news is that the new engine has been run in, and is running well with the new Roush exhaust and fuel pump upgrade.

BUT - the really good news is that I was concerned to make sure that the engine was properly mapped, and fuelling was OK, so I talked to Trevor at Roush and he agreed to check everything over and map the car to ensure that all was running properly (and more importantly for me - safely). The main aim was to ensure that there would not be a repeat of the piston melting phenomenon previously experienced.

The engine is basically standard apart from the exhaust and fuel pump/wiring loom upgrade, but does have the FP Intercooler and a BOV of somewhat uncertain origin (I/C and BOV already fitted when I bought the car).

Bottom line is that after several hours, and much time spent on the dyno and attention to detail (alot of which I freely admit I don't really understand), Trevor was finally happy that the engine was running very safely, fuelling properly, and was basically set up correctly.

Oh, yes - apart from running safely, there was the bonus of the performance

Max Power - 442 BHP at 6200 rpm (390 atw)
Max Torque - 416 lbft at 4800 rpm

All I can say is that it pulls like a train!

I know there have been many threads extolling the virtues of the Roush exhaust, but I'm afraid I have to add my voice to the others. The exhaust/fuel pump package, but above all the mapping by Trevor to ensure a smooth and safe power delivery totally has transformed the car. I cannot recommend it highly enough. (Goodness knows what it's like driving some of the cars that they've done more extensive work on!)

I'll shut up now - think I've gone on long enough...

(a very happy) Conrad.

What boost is it running at now?


Boost is a maz of 14.07 psi (just under 1 bar) at 4300 rpm
He then adjusted it to drop off towards 0.75 bar at higher revs. So it's not running excessive boost.
Here's the plot:
