Hi all

This is following on from a post I made here http://www.skylinesaustralia.com/forums/in...howtopic=184222

Car is a R34 GTT with the following power mods - split dump, hiflow cat, and fujitsubo catback, apexi pod, stock SMIC

The EVC was tuned very nicely on the dyno and so I thought I was all set. 9.5psi on the low setting 11psi on the high setting. I dont want to go any higher.

Problem is I am getting a peak reading of about 11.7psi on very cold nights when I floor 1st or 2nd gear. (on LOW setting)

In 3rd gear, Ill get about 10.9psi max.

I didnt try 4th gear on the street.

Has anyone who has mildly modded their R34 experienced similar issues with boost peaking a bit higher than what was set?

And do you find ha the boost tapers off because of perhaps a spark, fuel, intercooler, or stock ECU issue when running 11psi?

See attached dyno sheet (red line is low setting, blue line is high setting)

    • Oh man what a deal.... Funny enough (well not really) I sold a car to some old dude (buying for his Daughter) on a Saturday, He asked if she could take the car now and pay me the money on Monday as the bank wasn't open. Needless to say I told them to come back with the cash or get f**ked! Luckily the money seemed to magically appear in his pocket a few minutes later, so it all ended well (for me).
    • Gucci bags tend to hold their value well, so someone’s definitely going to get a nice find here.
    • @Ozdavroz Not going to get a better deal than that. Cash up front and ongoing payments. 🤑
    • I wouldn't even move it like gTSBoy is saying. I'd seriously do what Duncan is saying. Unplug the injectors, and unplug the fuel pump.  Pull the spark plugs out. Have a look in quickly with a bore scope if you want. At most, you can't spray a bit of oil into the bores so there is lubricant in there while you crank it. (Don't fill it, as it's only going to enter the exhaust, or spit at you out the spark plugs holes. Before cranking the engine on the starter, after a 5 year sit I'd probably prime the oil system manually. Easiest way to do so is to look at buying an oil filter relocation block, fit it to the engine. The pressure line going into the engine on this block you can then shove into some sort of oil pump, or put it into a bottle, with that hose going to the bottom. Fill bottle up with oil. Now seal the bottle and add a compressed air line to the top of the bottle. Feed compressed air in, about 20psi will be PLENTY. This will pump oil through the motor. Be aware, it also means it will drain back to the sump, so make sure you don't end up over filling the motor Now bolt the old oil setup back on (or fully install the remote filter system).   This way you've at least pushed fresh oil everywhere, then you're letting the motor crank to then do its own oiling. Then I'd tap the key to make sure it can start to crank, if the motor free bumps, then I'd just hit the key and let it crank. After letting it crank and seeing you can get real engine oil pressure, put new spark plugs in, reconnect the fuel system electrics, and send it.   Additionally, you can look to remove the fuel feed line to the rail, and divert it to a tank so you can get the bottom of the tank shit out, and just incase there's some crud sitting anywhere that gets passed the fuel filter (or is already ahead of it).   If fuel injection at the injectors ends up appearing to be a problem, you can dump the injectors into an ultrasonic cleaner for a quick flush clean out. Note this isn't as good as new injectors, or getting them pro cleaned and flowed    
    • All I can say is, that's still bloody awesome! No plans on caging it I'm guessing?
