  1. Slimline black 'VSPEC' plates for sale. Offers above $2000.oo Phone Ed 0411392676
  2. Yep, until you run out of dyno allowable road speed
  3. In my opinion, exactly. Dyno's are set up to give a fixed road speed increase with time, e.g. 12 kph/sec. If you use a taller gear the dyno stills holds the wheel speed to 12 kph/sec, giving the dyno sweep longer time from start to red line. This then gives the turbo's more time to spool. Should give a quicker spool up , not by time but by road speed, which is what the reads. I prefer dyno runs in rpm not road speed. This shows what the motor is doing more acurately than the unknown gearing of the car. People on this thread do not even knowin what gear Ben's run was done.To me it seems 5th with a 4.1:1 diff. Only way to get 230 kph at 8000rpm. He does use 4th sometimes,and 5th soetimes. He tuned my R32 GTR many years ago, great job too.
  4. Ben's dyno using 5th, mines 4th gear. Ben's getting 28.7 km/1000rpm. Std is 33.5 5th and 25.5 4th. Half way between. Ben tends to use 5th gear as it give less gear box loss, 5th is 1:1 ratio. Unusual he starts the dyno at 3000 rpm
  5. Please read the thread in 400 kW. I posted the link to get a reaction. Was not expecting a bad one. I have no axe to grind, just want to share my experience on the best GTR forum in the world. I guess the comparison I can make is I spent about $14,500, all work done by others. I now have close to a brand new motor, new turbos. Surely this is valuable to others.
  6. Check out post number 1515 under 'got over 400 kw atw" 3.0L with -5's 404KWAW
  7. GTR R34 RB30 conversion RB30 block rebuild by Pro engines, inc forged pistons, rods. Nitto oil pump Garret -5 new turbos Aftermarket injtrs,manifolds, cams, detail not known Reconditioned GTR head Drives like a V8 On boost above 2500 rpm, smooth as, with progressive boost increase. Torque tapers off above 5500 rpm, but still 77% max torque at 7000rpm Interesting to compare this with Racepace Ben's WOW 2.9 Low rpm torque better than Ben's up to 5000 rpm, then Ben's better revability takes over. Worth mentioning this dyno done on 4WD. Ben's on 2WD. 4% difference maybe? Also note, Ben's diff is very short, 230 kph at 8000rpm With RB30 bottom end, rpm limited to 7200. Max torque at 3500rpm and comes up nicely from 2500 rpm. Estimated air flow 32 lb/min at 21 psi each turbo. Equates to about 10.5 FWHP per lb/min air.
  8. GTR R34 RB30 conversion. Pro engines full rebuild botton end Recoed Gtr 34 head Garret -5 turbos new cams, injectors, manifolds, aftermarket, but detail unknown. 3.5" exhaust, 100 cell cat Tuned for max low rpm torque. 1 bar boost at 3000rpm
  9. What's the latest on engine number change without an engineer's cert for RB26 to 30 in a R34 GTR?
  10. still cannot download pdf file from item 1. Can anyone help?
