Well done guys, gone are the days when you had to absolutaly ring its neck for a 10.3, now it runs close to that on a back off. It is well deserved, all your patience and effort have payed off. up 4 another Queensland trip?

PS. Hope is all well with your new addition also.

Yeah Stuie, deep in my heart of hearts i knew the car wasnt capable of a 9 with the 2530's...not with a synchro box anyway...they simply cannot be shifted quick enough. The car needed more MPH and less weight to cope with the handicap of the box. Losing 100kg out of the car and the addition of more revs and more power from this new engine has made the world of difference. I am still running a "garden variety" Power FC so i have no "two step" ignition cut on launch, so to 60' a 1.44 without one is simply unbelieveable (its the second fastest GTR 60' in Aust) on radials. So Mark Jacobsens prediction of 9.7 seems on the money when the car is properly set up and a few more passes under my belt.

that 9 was run on my 23rd full pass of a drag strip.

this is the only RH9 car that has used low mount turbo's and has beaten kiwi Arthur Eyre's all time world mark of 10.17 for a "bolt on turbo" GTR.

Awesome effort well done. The amount of very fast GTR's in Oz is getting out of hand.

Have you turned the Nitrous on yet?

No NOS as yet

Sonoco Max NOS fuel (which surprisingly does not make much more power than pump fuel due to its slower burn rate and oxygen content...about 27kw more in the top end)

Shane high 107's to half track

Dave...the pulley drama being resolved over the weekend

and we now use HKS GT-RS turbo's...the 2530's were upgraded some 18 months ago.

Does anybody have the run on video??

    • Ok guys thank you very much. GCG highflow it is then 🙂 
    • forgot to mention that when it does this it does not kill the engine, but I have not kept the pedal down long enough to let it, as I see no reason to beat up on it as its got to be something simple, small and dumb causing this.  And as soon as I let off pedal, the engine returns to its normal super smooth operation and rpms re-stabilize quickly, once below 4k. 
    • neither stumble or cut really seem to be an appropriate term....hard to explain its like a rev limiter but at 4k, but it violently shakes engine and entire vehicle as the rpms will not rise over 4k, even with slow acceleration. as soon as it hits 4k, it sounds like entire spark is lost entirely. plugs were 1.1 which I used as such, but later put in new plugs gapped down to .8 changed back after issue arose when I replaced the coils, still does it with either plug gap...damn and it was all running so good.
    • Oh how times have changed! I actually lean it out relative to my water/methanol injector duty cycle. The methanol adds a lot of fueling and you can then lean it out even more due to reduced knock. 
    • Yeah my thoughts are the same, a well thought out WMI setup, would be slightly ahead of just straight E85 and you're also chemically intercooling the charged air, dropping it even further. This is why you need to add so much more fuel as soon as you spray. I remember someone taking me through their set up before (Dennis, has a R33, lives around Cabramatta - no idea if he's still around on this forum). He would target AFR 10:1 on 98, then as WMI ramped on, AFR would lean back up to 11:1. Amazingly, he did this all through his PowerFC, a relay to cut power to his EBC solenoid if there was not enough line pressure on his WMI kit. And of course, if there wasn't any boost made above gate pressure, you wouldn't be accessing the load cells with heaps of timing for WMI. One downside to that rudimentary setup, once the WMI came on, the EBC would unleash the dragon, and of course all the timing. Tyres would fry lol.
