The day has commeth - the old girl has finally hit the dyno!!

Today Mr Goode and Mr Rowe took my car over to Scoobyclinic for a play.



Before their visit I was pretty comfortable with my build and the spec but I had a few concerns - areas which I felt might hold back the builds potential:

1) Ignition - The car is running OEM :mitsi: Coil packs with uprated Magnecor leads (not sure on the plugs - Mat?). I was worried I would suffer spark blow out or simply a weak spark.

2) Fuelling - The car is running OEM :mitsi: lines, Aeromotive 340L/H Stealth pump, AEM FPR, Aeromotive billet fuel rail, Injector Dynamics ID 1000's. I was concerned the pump and injectors would struggle feeding a high revving long rod motor and a FP Black running decent boost.

So anyway - Mat and Dave did hit issues today. The problem - 2) Fuelling
My fuel system simply couldn't deliver the fuel required. Dave took it as far as he wanted to but there was no point pushing it. Mat suspects there is a problem with fuel flow. The Injectors were running at 105% duty cycle at a fuel pressure of 3.5 bar.

Here are the initial results:
1.7bar on Scoobyclinics Dynodynamics = 395.8whp



Flywheel horse power run at 1.7 bar = 512.1 (22.71% trans loss or 520.1 MLR 24% fudge factor )


Part of me feels a little disappointed but deep down I knew it wasn't going to be perfect straight out the box as I've made compromises. I would be naive to expect a new build to jump on the dyno and perform flawlessly without any issues what so ever....

However.... and it's a big however -I am very pleased with the results because they clearly show the car has heaps of potential. The shape of the curves look mighty impressive already at low boost! Look at the frickin spool for a non mivec 2.0L 4G63 fitted with a turbo that flows more than a regular GT35r!!!

By studying past development work from the likes of Conrad - we can see the old style black was very happy being pushing to 34psi.... I've talked to Robert@ForcedPerformance and he reckons the turbo would be fine at 37psi - over 2.5 bar (providing shaft speed and EGT's are acceptable)!!!
Lots more boost to be run as I'm currently running under 25psi (1.7 bar).

Dave Rowe ran zero ignition - so there's gains to be had there too.

So yes - there are issues to overcome (the fuelling a known one). It does look like I need to throw even more cash at the builds fuel system to do it justice - but I remain hopeful - there is a lot more to come.

I would like to say a big thank you to the lads from MG Autos for doing a fine job. I would also like to say a special thank you to Mr Motec himself -<<Dave Rowe @ Electronic Performance Systems Clicky>>. Top job lads - I can't wait to get the car sorted and spin the rollers again asap!

Watch this space for Dyno Day #2!
