It's all about preventative maintenance for me as this car cops a flogging. Work done by John at Precision, and I recommend him.We went with a 11 blade Billet wheel upgrade, machined housing, porting and flapper mod.Car was tuned by Dale at Castle Hill Exhaust on Eflex E70.Did valve springs just prior.The car arrived with a leaking exhaust manifold as usual and this time was machined to fit and also fitted some gaskets to hold boost. Power was way down.I wanted 2 new tunes.1 drag tune at 21psi on Eflex which went nearly 390rwkw, and a very safe, rich tune to handle many circuit laps at 16psi which went a bit over 360rwkw.With the same exact same set up (apart from Valve springs) the car previously made 346rwkw on Eflex at 18psi (a tune that I never used, and actually reduced to 17psi a bit later for about 320rwkw). On 98 it made a bit over 300rwkw at 18psi. Dyno was recalibrated in between so the numbers probably aren't that important.Though, after the recent turbo mod.....All I can say is.........WOW!!!! This feels a lot more than a 40rwkw gain.The car pulls like a turbo diesel truck off idle, with a PHAT, obscene midrange and finally the top end I have been lacking for years.I used the 390rwkw tune recently at the Nulon Nationals round 3 at Cootamundra airport too and the results on fb speak for themselves. "Usable" power on the airport strip, all the way from idle to redline. Progressive and one of the best bang for buck mods I have done.Can't wait to try the new 360rwkw tune at Wakefield in October.Been wanting that 7 for a while now!

Just means you have to pedal it around the corners a bit. 1 Link to comment Share on other sites More sharing options...
Bellato Donating Members 2,713 Member For: 14y 4m 12d Posted 26/09/14 05:19 AM Share Posted 26/09/14 05:19 AM Any plans for a 98 tune on this setup? I was going to do this and go prices from John but was only going to be an extra few hundred for a new gtx3576 and its a new turbo as opposed to my old one so decided to hold off until I can afford itIf anyone likes this set up I have a 60,000kms fg turbo with stuffed compressor wheel and rear housing that you can do these mods too Link to comment Share on other sites More sharing options...
