Great work Eric, looking forward to seeing how it performs at MTC.

Those clips - mere fleeting glimpses... anything longer?

I will be doing some more track events soon. Unfortunately as soon as the car starts to really develop boost, its either about to break traction or you would be over the speed limit

I've been driving the car for about a week now and I love it! Although, it is nearly a bit too much to handle. I guess I am just adjusting. 

Torque everywhere is a really great feeling. Just have an intermittent belt squeal issue to sort through and I will be going to a skidpan on saturday

you will be wanting more power in the not too distant future Eric!

Quick update. Had a rushed dyno run this morning. made 213kw with a slipping belt and pig rich. 

The car also made 440nm of torque, with most impressively the car making 350nm of torque at approximately 2500rpm. The blue line is my current setup, purple is NA
 
Hopefully will go back in the next few weeks to play with a few things.

Looking good Eric. No need for third gear again

Why have they used third gear for the run ?

I only noticed that this morning, it looks like they used the incorrect gear. Its getting another few runs in a fortnight to tune the fuel pressure and other settings, so i will instruct them to use 4th gear. They are also making a proper intake for me. 
 
My belt squeal issue was discovered yesterday. the tensioner is wobbling around a lot and not remaining tight. I have ordered a genuine Toyota one. Hopefully the installation will remove belt slip.

Good stuff Eric! 

Yes 4th gear is the most suitable gear to use on the dyno (not in all cars, but at least in an SW20) because it's the closest to a 1:1 gear ratio, but this is NOT as important as many people seem to think it is. 
Using a lower gear will increase the torque at the wheels, BUT it will also reduce the wheel speed proportionally, so the resulting power at the wheels is exactly the same. You may see a small power difference between gears due to changes in efficiency in the transmission, but that's all. 
One of the main reasons for using a higher gear on the dyno is so that the run takes longer and you get more data samples. Another reason is to help prevent tyre slip against the rollers.
