Hi guys-I had the crown at Jazmac on saturday-Sean is my name. I'd have to agree that there seemed to be a lack of powerful cars there. Perfect weather for it though. I was certainly feeling my age there too......

Where were all the skylines/supras/turbo rotors? Mind you I did enjoy the R32's as always-one on the best looking cars to have ever come out of japan methinks. It was the first time I've had a car in such a day and it was most enjoyable.

As for the crown, yep, it pulled 257. It's only a baby in terms of finetuning, as I've only had it on the rollers once before in current trim. The main problem it suffers on the rollers is masses of wheelspin. When it was dynoed a month ago it made 281 rwkw (shootout mode at blackwood dyno tune) on 13.5 psi and premium-although we needed to strap it down ultra hard and had 2 big guys in the boot for ballast-and even then it was breaking as the boost was coming on (at one point we filled the dyno with so much tyre smoke we had to leave and let it clear for 5 mins). It's not that the car is a mega HP animal, it's that the boost hits really quick and it generates masses of torque instantly-overwhelming the tyres (2500 stall converter doesn't help either). For saturday I put 1.5 degrees extra timing the hope of cracking 300, but without ballast and serious strapping it was a lost cause. Looking at the roadspeed on the printout, that 257rwkw peak was somewhere around 3900 rpm before it let go, and it doesn't make peak until 4800rpm. Next time I'll bring a couple hundred kilos worth of sand bags for ballast. As it was driven off the rollers you could see how hot the tyres were as they had gone all shiny-they even picked up a full coating of the fine gravel out the front of the workshop (took 200m of driving before it all came off). The problem was that at a day like saturday there isn't time to strap every car down and you can't have 3 dudes in the back for ballast!

I had to leave early, but was told that someone in an R33 knocked me off the 6cyl spot late in the day by 6-10 kw (bloody datsuns =-)? I'll bring ballast next time!

The Falcon put on a lovely display of quiet, reliable yet monstrous power. Martin-is that a CAPA promo vehicle or is it yours? That VK ended up getting defected in MtBarker too. I took the long way back to the freeway just in case..........

A well carried out day by Jazmac I thought. (A whiteboard for results and a PA system would top it off-but certainly no complaints here)

Martin-my email is [email protected] and that's probably an easier way to catch me.

Cheers guys

Sean

Thanks mate. Its CAPAs car, Ive just been doing some tuning stuff on it. The poor thing as 3000km on the clock, all of which have been generated going to and from V8 Supercar rounds as a dedicated burnout car. It was born at the start of March, went to Clipsal, Puke in NZ, missed Darwin, and is now on the way to QLD for the 400 (?) on this weekend. All stock save for the blower and a clutch. Been through masses of rear tyres, and is very liberally coated in rubber. Not bad for an inferior quality, poorly built, badly engineered pile of poop eh? With 120rwkw it would probably last 25 years. Food for thought.

Wiplash, am I correct in assuming you were the fellow I would have grabbed my entry from and handed cash to? Given the fact you would have known a few dudes there, do you know of anyone who got any video footage of my crown on the rollers? I'm dead keen for it.

It was a well organised day mate-cheers.

Sean

    • Hi guys . Can someone help me  I bought an Android screen for my Nissan fuga but it won't turn on   
    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
