yes you can

 

rb25des has been done...i have seen pics....

Thanks man, Ive gotso much choice RE what option I take..

R33GTS-T

R34GTS

R33GTS-Supercharged

R32GTST - a bit old..

R32 GTR- If I can get it imported for around $20k I doubt it and they are a bit old..

If you find any Supercharged Skylines post some info and or pictures people.. its a path that isnt looked at often.

it has been discussed many times on the forums, but is rarely done because there was a factory turbocharged option. most people just buy the turbocharged car saving time, money, hassle, and tuning issues

BUT... a supercharged skyline would be a very nice machine and is definately possible to do

Can you.. Supercharge a skyline?

It might sound stupid but ive just gotta know..

I've seen photos of an RB26DETT with a supercharger. The supercharger took care of the lag issue (as you know these puppies don't suffer from lag) in the low end of the RPM range, but cut out when boost came on with the turbos.

Don't ask me what the power figures were as I never found that info out, but it looks and sounds like a nice concept.

apparently the real issue is the fact that a S/C will run out of puff at high RPM

hence the reason they are mainly used on V8s (they dont rev very high)

on a skyline it would be great off the line

but once the revs get up there it will be out of its effiency range.

dude, V8 REV HARD if they are built and balance right, my old 302 windsor reved to 9000rpm!!! swwweeeeetttt sound......

As for superchargers runnign out of puff, what about the drag cars? I know these are 6/71's+ but they work a treat! The biggest dilemma in 'twin charging' is the crossover point f supercharger and turbo charger... the best example is the nissan superturbo march.

the 25/30 shown in the pic above is NOT going to be twincharged, it is simply an SC-14 mounted on a 25/30 combo. i have my doubts about it, but nizmodore is going to find the limits of the little SC-14 on that engine i have no doubt.

i am currently gathering parts to build a twincharge system on my RB30 with an SC-14 and a giant turbo. don't worry about switching between the two compressors or anything, just set it up as a simple blow-through system. here the turbocharger feeds straight into the blower, which is primarily there to increase "off-boost" response (not that there is such a thing with this setup) and spool the turbo up very early. this means you can run a BIG exhuast housing and have a huge stonking top end power figure with solid midrange and low-end torque.

say the blower makes 4psi (as it does at the moment for me) right off idle, you will get massive exhaust gas flow at very low rpm. turbo spools early, and you then simply add the two pressures to get your final boost level. 4psi +10psi = 15psi (the blower gets more efficient as it's intake pressure gets above atmospheric) into the manifold and viola, easy twincharge setup.

fitting it all in and stopping belt slips are the two main challenges. charge cooling is another, but i'm just going to run an intercooler and an aftercooler. water/air and air/air respectively.

      How dare you sell your unreliable Skyline and buy a reliable, Toyota/Yamaha car with a strong gearbox, torsen LSD and Toyota reliability. At least you won't need to worry about oil pumps, big catch can, oil restrictors, blowing off power steering belts, sheering off 3rd gear, failing ABS relays/pumps, etc.

      Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

      Leak from Tokico BM50 Brake Master Cylinder

      The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/

      Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.
