Hey Impellor,

Did you do the crossover and plenum mods yourself? Is the crossover a restriction in the standard system?

Yes, I did the porting and polishing myself. My feelings are that as the air moves through the piping (factory, but have wrapped to reduce heat and pipe expansion) to the crossover it will be affected by the hot environment created by exhaust and turbo. So by increasing the crossover entry and exit, it allows for improved velocity. Also by smoothing the internals of the crossover the flow will become less turbulent, therefore an efficiency gain will be achieved. Less turbulence equals less friction, less friction equals less heat. Less heat equals more power. How much more, well the the $69 question.

If I was purely after numbers I would have tuned the car in the middle of winter. But as heat (intake temps) is the main destroyer of engines. I decided that to tune in the middle of summer was a safer opinion. This thinking could well be flawed, but I haven't seen any evidence to the contrary.

My goal at this point in time is to have a nice smooth GT style car, something that comes on progressively and linear. This car will never see a drag strip, and hopefully will provide many years of reliable cruising. If I do get bored with it, I will add a good cooler and piping, and a turbo back exhaust which should see it up to 350RWKW's.

But realistically I'm not interested in throwing a heap of boost at it to make a number, its about tuning it to make efficient power. If it only makes 267 RWKW's as Jet has alluded, so be it.

Hi all, as the title suggests the results are in. The instructions from the begining were very clear. SAFE, SAFE, SAFE. Don't care about the numbers, just has to be SAFE.

After 6 hours of dicken around, replacing coils, and going back to the original thermostat. The car pulled 396.1 rwhp at 13 psi tapering down to 12.5 psi. Heat was a bit of an issue as the intake temp was at 40 *C. Not once during the tuning did we see a knock light, so I was very happy with that also.

The AFR's and psi sheet will be posted, along with the power figures shortly.

I would like to thank everyone who has provided sound advice, for a wonderful experience. I was lucky enough to be in the car the whole time it was tuned. Peter from Real Dyno Performance (who has been tuning for over 30 years) was absolutely fantastic in explaining the whole process. An absolute professional in every sense of the word, and a true gentleman.

I would also like to highlight how Real Dyno Performance were so helpful, and went way beyond my expectations. The guys there are so down to earth, and I appreciated their no bullsh*t approach. In fact I'm so impressed I have put one of their big ORANGE stickers on the back of my car (which I have never dreamed of doing previously), as a show of genuine appreciation for their fantastic efforts. Further, there workshop was spotless, which to me shows that they take pride in their work, and their commitment to the customer is unquestionable.

After the test drive I had goose pimples. The difference in performance was just incredable. The tune has a good dose of torque down low, and amazing pull once your up and going.

Cheers
