  1. ***Money pit update*** All new alloy 3" v-banded intercooler piping, cost a fortune but no more intercooler piping blowing off being a ute, traction is non existent on the street even with radials on, trying to get used to the acceleration at the track is an awesome learning curve. Willowbank had the hot rod and nostalgia reunion on that weekend, so in the 5.5hrs I was there, only got 4 runs. 1st run - 132mph (red lit with a transbrake fault), 2nd run - 11.0@140mph (left off the foot brake without boost), 3rd run - 10.3@139mph (3000rpm launch, short shifting through the gears), 4th r
  2. I finally have the brakes all bolted on and bled, stopping on a dime. but unfortunately the Work Emotiion 18" rims didn't leave more than 0.25mm clearance, so they had to go. I fitted up 19x9's, and 19x9.5 mustang rims, offset is way off being +52.5mm for the rear and +45 on the front, so for the moment im running 35mm bolt on spacers on the rear, and 20mm's on the front till I have a more permanent fix.
  3. ok, transmission is back together, another full build, same specs as before but now with a 6pack forward clutch arangement, 36 element pro-mod sprag and drum, billet alloy intermediate shaft and a freshen up of the converter. good for 1800+rwhp and 1500ft lbs. I still havent turned it up, and still havent installed the 4bar map sensor. I figured I should try and put down the power I have without blazing the tyre before putting more into it. In other news I figure if im planning on running 150+mph it would be good idea to stop at the other end.. the 2 piston calipers and 322mm rotors
  4. we had the car back on the dyno a couple of weeks ago, turns out the internal 3bar map sensor was struggling with any boost over 28psi, so I have picked up a haltech 4bar sensor but yet to be installed. still at 27psi but inlet temps have dropped significantly and we are making solid power without too much timing. took the car to one of those torque time sunday morning events at qld raceway, bit of a nightmare morning. arrived, and bolted the radials on, pulled out onto the tracked and put a little heat into the tyres through first from about 40kph, selected 2nd and felt a little s

  6. it's all about weight transfer, there is nothing wrong with leaf springs, and there is a lot of development put into them. Gazzard Brothers in Toowoomba are the leaf spring kings, mono linear rate springs, with traction rods are the go, along with a bound and rebound adjustable rear shocks. A good set of 90/10 (fast extension, slow compression) bound and rebound adjustable front shocks will prevent the tyres from unloading too quickly (break out into wheel spin would be the result).. I wouldnt be too concerned about tyre width if you dont have any sidewall. I changed from a 285/30r
  7. it is my own fault really, I have experienced this in the past with a customers 600hp SR20 (huge power for an SR back in 2005). he also wasnt running a BOV, and the same thing happened to him (lost compressor nut). as the compressor wheel is spinning at 180,000rpm and comes to an almost dead stop, the inertia of the nut wants to continue on. My nut was sitting loose on the bottom of the compressor cover inlet. in other news, my 1500hp tailshaft has been installed, turbo has turned up and installed still representing for the low mounts fuel line fitting brok
  8. well, all good things come to an ends, and in this case, my 11yr old turbocharger spooled its last spool... fluttered its last flutter.. this was a result of my turbosmart blow off valve failing. the compressor flutter was getting louder and louder, and the nut off the compressor wheel tried to take a walk. happened 20mtrs from work which prevented catastrophic damage. so a new turbosmart raceport blow off valve is going on, and decided on a half decent sized turbo. the new gen2 7275 cea precision should get me over 900hp at the tyre, but more to the point, 800rwhp
  9. not a great deal has been happening, trying to enjoy the car a little. been on and off the dyno a handful of times. made 660rwhp on 19psi with E85 before we hit the wall with the fuel pumps and wastegate. Fitted a new turbosmart 45mm gate w/ 14psi spring and a Magnafuel pro tuner 750 pump, and back on the dyno making 716rwhp @ 22psi on E85, then the alternator sh*t itself.... with the new alternator fitted, we turned it up to 27psi and the conditions weren't ideal on the night, strapped it down harder and harder but we couldnt get it past 720rwhp without breaking into wheel spin. the turb
  10. 288° duration, 0.508" lift, 112-114 lsa peak torque 1350nm is at 3400rpm, and 7000rpm redline
  11. 10psi less, but not same power.. atleast 10% more power, made 606@26psi through a t56, now making 609@17psi through a th400 with 3500rpm stall it cost a sh*tload to do the head and cams, im not regretting it. basic head reco which blew out to ported and polished head, o/s valves, springs, ti retainers $4.5k, match port inlet and exhaust manifolds $400, then cams to make the most of the head $1200, adj cam gears $550, timing chain etc $600, factory ecu wont run it elite 2500 wired & tuned $8250, cams too big for brakes CVR vacuum pump $500............ errr...starting to regret i
  12. I have a brand new Mac solenoid being controlled by the Haltech, Ash (tuner) runs the same setup on his 7sec LSX RX7
  13. yep, it would be a $1000 to replace it
  14. 100%, the reason to upgrade wasnt due to the extra boost, the older Tial 44mm gates are becoming increasingly difficult to find springs. I have to pay $140AU to purchase the springs I need from the States
  15. 18psi is all we could get on E85, wastegate needs some attention. havent decided whether to throw in some new spring combination into the (older generation) Tial 44mm (17psi), or upgrade the gate. im a bit dissapointed with only 50hp gain with e85, drive much nicer, idles better, but with the excessive fuel consumption I dont think it is worth running e85 at this boost
