Supercharging?

[sidewayssam]

just had a quick look through this forum and cant really see anything on supercharging, has anyone here have or have seen a supercharged rb25 and what brands do the, cheers

[paulr33]

its been done before - try searching on it

from memory stockymcstock has a supercharged rb30det

[PM-R33]

I've seen it done on a RB a couple of years ago, personally i dont know why you would bother with a RB, for the money it would cost, you can get greater gains for less money with a good turbocharger setup. It is different however and pretty cool to see people doing something a little bit different.

yehi was thinking maybe turbo and supercharged, like some rallycars, my engine is already turboed and rebuilt but yeh i was thinkn to do something a little bit diffrent

[paulr33]

i think when i look up supercharging on a skyline and read into it - it comes out expensive and lots of custom work

if you are a fabricator / mechanic then i think its fine - but for your average dude who just wants a bolt on kit turbo is easier and better $ for kw etc

Ah ok. Yeah a twin charged setup would be a good setup however extremely expensive to do and set up correctly. Would be interesting to find out how much something like that would cost. Has anyone in Aus ever twin charged a RB25?

[paulr33]

yeah stockymcstock has done it he has a superchaged rb30det with a gt40

it looks like a complicated, lengthy and expensive process

do a search on some of his posts in the rb30 thread to find out what he has done etc

[TTT]

yeh and find his vids he's posted.

absolute monster.

Fake.

This is one hell of a set up

and the site with the build

not a 25 but a 26, I have seen it in person and what a monster. Now this motor is in a R32 GTR cant wait to see a run on the track with that.

[johnbarry88]

KISIN is it really fake?

[Guilt-Toy]

i was thinking about putting a toyota supercharger on my rb30det, make it come alive much earlier.

I was looking at it last night, and there is lots of room to put one there.

I dont think its fake it is in the same spot as the one in town and just has dual turbos. They created less lag but rob your top end

[sidewayssam]

okie dokie then, i might just spend my money on something else,

Not true...kind off. If those superchargers are twin screw, then they will not limit the top end power at all.

As for the pic, its been discussed before, and that particular thread came to a conclusion that it IS fake. Fake or not, its crap coz there is not way you can fit all that in a skyline engine bay .

ask stocky, from memory he said it wasnt worth it. its alot of time and effort for not much results, just get a correctly sized turbo, and with the leftover cash go RB30DET

that pic of the twin charge kit isnt fake either, i thought it was at first too because the pipin looks dodge, but i've got a pic of it from another angle, and from what i can tell its real

the only thing with that is with the way the piping is (from what i can see) the system wouldnt work, as they are booth running in parallel not series, and there doesnt seem to be any sort of valving in line either, think they just threw it together to try and look good lol

i love suprechargers, they are a great upgrade on an NA engine.. hell i would love to put one on my V35. a guy on WA had one on his V35 before he sold it..

but for an engine that already comes out turbocharged, like the rb, it just seems silly to bother going with the R&D of a supercharger when you can just bolt up a different turbo if you're not happy with power. that alone is reason enough not to bother in my eyes

Very well said. Pretty much sums it off perfectly.
