No RNS11Z its from a white series 2 with internals,tomei cams, greddy plenum and a td06 25g

I made just over 400rwhp at a touch over 15psi and have now had the car tuned with a power fc, why do you need so much boost to make less power, maybe the td06 is worth the extra $$ hahaha

Well considering i dont have cams and cam gears, once i get the bigger injectors and bigger fuel pump 440rwhp will be easyly made. The reason why i had to use such high boost to get the power levels its at now is because of my fuel problem. If i were a mechanic.. hey id solve the problem myself and tell you the reason why its not making so much power.. but im not so thats just the way the cookies crumbles.

As I said in another post, the type of dyno used does matter. I read in a Fast Fours that the JUN s15 in Perth pumped out around 700hp (???) at the wheels on one dyno, only to produce a comparitively measly 550hp (or thereabouts) on another dyno. Well, actually it's still damn impressive but not so much when compared to the 700hp figure :O Best is to have a dyno day shootout for comparisons sake.

Generally dyno's do not vary that much.

Most of the time they are within 20rwkw of each other.

Well in Adelaide they are. All depends if they were both running the same mode etc. I think it is shootout mode that takes in to account temperature etc is it? If so that is the one that should be used.

RNS-11Z,

i'd like to know what exhaust housing you have with your GT35 as this in itself would restrict the amount of power that you'll get from your engine.

for eg,

the GT35 with an A/R .63 exhaust housing (714568-0003) is rated at 550hp whereas the core itself is actually rated at 600hp.

btw, does the turbo boost/power come in pretty quick or is it reasonably laggy?

Tune can make a HUGE difference. I was getting 230rwkw at one dyno - four hour tune, 257 at another days later - this was just a basic 'interim' tune (until gaget and cams) and it took less than an hour.

martin donnon explained that the only way to accurately compare dynos is to use shootout mode, and punch in the figures measured in the dyno bay at the time of tune - otherwise its not really an even playing field.

Out of interest, the correction on the day I got the 257kw tune, was only 1.029 so bugger all anyway:p

True, Steve does about 50% of SAUWA cause he does a great job, and doesn't bullshit us.

It seems that all of our turbo's are making similar levels of power, but making the power quite differently. It will be interesting to see what happens when we all push the turbo's harder.

Thanks for that site RS500. Much appreciated. Yes it is laggy but its just the way i like it. The part no: on my turbo is FC 6027J then its 706451-5. With a .7 A/R rating front housing (if i am correct but it has .7 stamped on the front housing). Not sure the size of tge rear if its .83 or 1.06 or .63

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
