After a good learning curve in 2015 the team's knowledge of tuning the GT86 continues to grow and the winter of 15/16 was spent designing new product to make the car much quicker in 2016.
The first problem was fuel supply and we wanted to keep the original fuel tank so our "road" customers could follow us and get their cars up to similar power levels.
We replaced the standard fuel bucket assembly with Avo's high capacity unit which allows much more fuel volume around the 265 litre per hour uprated fuel pump. From the pump we are now using -8AN stainless braided fuel lines, splitting symmetrically under the intake manifold to -6AN and then feeding the standard fuel rails which have been modified with -6AN fittings. Also the direct injection feed has been 'T'd off the -8 line.
Back in 2015 we had reached the limits of theAvo stage 4 turbochargerand with our new fuel system we could safely push the limits further. Working closely with Avo Turboworld certainly has its perks and we were the 1st to use the newAvo Stage 5ball bearing turbo! Based on a garret GT30 and with a larger exhaust housing it has improved exhaust gas flow needed for higher flow. Now the engine is running at 1.5 bar to the 7,800 rpm limit.
As the turbo is much larger the pipework has been custom made to suit and is of larger diameter to increase air flow.
Also new for 2016 is the Toyo 888R tyres which will certainly be well tested!
And what a year 2016 turned out to be, with 6 races and 6 overall wins and 1st overall in the Toyota Sprint Series :)
The end of the season is a perfect chance to get the GT86R on the dyno and we recorded 514bhp :)
