Hey. There was a person at the auto salons that Supercharged his Skyline. Its a waste of money. He spend soo much money putting in a supercharger and got the power of a stock Gts-t (140Kw). Might as well just buy a stock GTs-t, will be quicker and cheaper.

As a very general rule of thumb, supercharging is good for down low, but useless up high (and turbos are the reverse).

Basically there is no particularly good reason to supercharge a Skyline, in fact many would argue its an inferior technology (including the man who designed the supercharged-6 used in Holden's Commodore).

Look for warpspeed's posts, he has some opinions and (more importantly) experiences that are vastly different to those expressed above.

from what I have seen and read the older type of blowers on the old V8s and stuff, the roots and screw type are pretty inefficient. But the the more modern centrifigal type ( vortech ) are a lot lot better in design. Very similar to a turbo in fact. They drain a lot less from the crank to operate as well.

As an example my friend supercharged his 3.2l V6 rodeo. When stock it had 76rwkw. They strapped a vortech V1-s trim @ 10psi to it. It hit 200rwkw at 6500rpm and the curve was still climbing hard but they backed off because the engine would have let go if revved any harder. This gave him incentive to do a full engine rebuild. He upgraded to the T-Trim and its now making 385rwkw @ 25psi and they havent sorted out a few little gremlins that are keeping it from 400. The drivers and the cars maiden 400m pass yielded an 11.9 sec pass on slicks that had not been warmed up properley.

i went to a place near me to get a quote on supercharging my r33 gts, for a custom setup including front mount and all the shit they wanted $12,000 Hahahahahaha

he said it would have made 200 rwkw (currently 107rwkw)

but that isnt an option as selling my car plus that 12 grand (so all up about $24-26,000)

that would get me a besat of a gts-t.

before i went in there i thaught that it would cost like 5-6000 to do it.

Chris,

300rwkw isn't cheap.

Unless most or some of the mods are already there to support it.

To get 300rwkw in a GTST from dead stock you are looking at a minimum of $7000-8000.

Because I've built another motor its more in the vicinity of almost 15k. :rofl:

But ahh well its all for my enjoyment.

When My other half says 'Your not going to get your money back'

I say.. 'I'm not doing it to get my money back.'

----

I looked in to it for my VS 5ltr Commodore before I sold it.

It was going to cost around 7-8k to get only just over 200rwkw.

I was told that to get more power from there I was going to have to start opening up the engine + a different trim etc.

It is expensive to do it properly.

Also, considering supercharged skylines arn't exactly common, the workshop would pretty much need to do all R&D work as well.

There is a big difference in labour between fitting bolt on parts and having stuff custom built for an uncommon application.

Also, depending on what was included in the $12k it might not be that bad (think management & tuning, exhaust, IC, labour etc).

Given a choice of spending $3000 or more on the car, why not go for the tried end proven method. I know that for that muchmoney I can get a stock GTSt to 250ish rwkw, but when it comes to superchargers its a lot more of an unknown.

There is nothing wrong with walking the less troden path, but be prepared to pay the $

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      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

      V37 Radiator removal

      By Duncan · Posted

      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.

      V37 Radiator removal

      By Duncan · Posted

      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.
