there are a few R31's that are super charged, can pull about 130 kws with about 10 psi (correct me if im wrong)

Thats funny. :D

Drop a RB25 head on a RB30 with a set of rb25 pistons to bring the comp up to 10.5:1 and you see that kind of power. :)

twin turbo supercharged..

now thats nice.

there are massive advantages of a setup up like this.

you can use a spuercharger for all the downlow boost. and have either one or two massive snails to finish off the job, if i had the money and time i would try and do something similar..

here's a photo..

i havnt really found any info on this motor ever tho.. if anyone could help??

I know why they call supercharges parasites.

 

Checking out one of the whipple flow maps I noticed to flow 500-600cfm it sucks around 40hp.

Yes, but, with a turbo you are also losing a lot of power due to the extremely high exhaust backpressure (usually a little higher than the boost pressure).

Where's Warpspeed when you need him.

I went throught the supercharging thing on in line 6 cylinder engines back when the dinosaurs roamed the earth. Admitedly that was on Holden Red motors. I really carnt see why it carnt be done now even better with the multi valve twin cam engines of today.

Considering my motor was making 497hp and 523lbs/ft of torque on pump gas and even more on alcohol !

I know nissan made a car (cant remember which one - one of those small cc jap race cars) that had both a supercharger and a turbo on it. The supercharger would give it the botton end power then as the revs rose and the turbo came onto boost it would change over to the turbo.

A supercharger has all of the advantages that a Tubro has as disadvantages(ie good at the bottom, running out of puff at the top, no lag, turbo has no reall loss of power at the bottom end, but the supercharger takes power from the bottom end of the rev range)

    • 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?
