I think before the cams Steve's R33 made ~250rwkw on 1bar with the .69 exhaust a/r.

Twin 3037S on a GTR has made 700rwkw. Obviously big cams etc.

But still quite respectable power.

The you consider the HKS 2835's that make up to 280rwkw on the RB25's.

correct, obvious that a car has bolt ons if its making over 300rwkw. But it didnt have larger capacity engine (RB26 internals) or port work - just bolt ons.

oh, and Joel, it made just shy of 260rwkw with a restrictive exhaust at 1 bar with a 0.63AR turbine housing, before the cams - that was with a 20 odd minute Martin Donnin tune, he just did a rough tune to keep it going until it was sorted (other mods added)

Interestingly, it only made 270 odd at 1 bar with the cams, but the CR was lowered to 8.6 to 1

LOL...but the the 2835 owner will wind 1.4bar into the strd RB25 to see what it will do...and many of the gT30 owners seem to pull the pin when they get to 1bar and 250-260rwkws

Soft my ass!!! I wound in 1.4 bar from my GT30 when i ran the 320rwkw at the selectamz dyno day and last years autosalon dyno comp

remeber this is an Autosalon dyno result too...

Ash we need more info.. Was it also a DD dyno or another type?

I just find it a little hard to believe an RB25 with GT30 achieving 369rwkw :P

more will come when i can scan the graph, it was a mainline dyno.

i suspect around... 20rwkw higher at a rough stab as i have 330rwkw a day before in the all hailed shootout mode on a DD dyno

was that 330 on ben dyno? What psi were you running and what fuel?

Did you have head/valve/valve spring work done when the engine was getting rebuilt?

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
