Boy it has been quite a long time since my last post. Been quite busy with work and travels and also with my family. Not easy finding time nowadays!
Well first up would be my dyno chart, should have posted it up a long time ago but havent got the chance. This was done after I have changed to a full 2.5in exhaust setup with straight pipe and rear muffler from Tonnka. All of the work was carried out by the main man of Tonnka himself and I must give my hats off to their work and quality of stuff they manufacture!! Also running water/methanol injection during this run.
As you can see from the chart above, I am very very pleased with the results. My only gripe is to smoothen the mid range to remove the 'W' in the mid range. To date I have also experimented with a different header configuration (4-2-1), very long primary, tri-y design which was custom made by Tonnka. Although this improved the mid range by a whopping +16whp, I lost quite a bit on the top end about -10whp. So I went back to the previous header which is a 4-1 style from Formworks. I have a new header from Tonnka which I have yet to try, let see how much it helps.
Tonnka Special for 4G93
Close up of the header.
Looks more like turbo header
Taken out after dyno- note color change after just 1 hour on the dyno
I have also got SP in the track at last and least to say I am still learning its new power delivery and also mastering all the gadgets on SP. Whats coming up, a revised brake setup and a new look! Watch this space!

That extractor is wicked and drooling :)
it is!! unfortunately it was not performing as well as it looks. the header comes up almost to cam cover level and requires the air cond fan to be relocated. also the ground clearance is massively reduced as the primaries are huge. a lot of heat management is required for this header!
wah bro larry is gonna love you man for promoting his products haha.....
Roger roger... indicators on... moving aside!!
Bro,
Respect! You are really pushing the 4G93 NA Bagus performance barrier!

andrew,
good things come to ppl who wait!
akatsuki,
the header in that picture is waiting for me to get back and try it on SP. Hoping it will provide a better performance than the Formworks unit I am currently on.
Hi Mr Akatsuki,
Bro Mugil is effectively Tonnka Skunkworks! :)
wow would love to see a picture of your current formworks vs the soon to be installed tonnka!
hmph,
