twincharging a b16b

[tarmac-]

Yeh true, not epic i guess, but a very nice useful setup. If that intake has some sort of cooling in it, water or ice etc, its probly one of the best turbocharged designs that can be made.

VWvortex Forums: 4 Cylinders, 2 Turbos, 1 Supercharger....Insanity!!

Epic yet?

[tarmac-]

Fuk working on that thing :p

[MMJA]

Wow that's what I call unique, never seen a back to back turbo arrangement like that.

LOL... Find the vid of that thing from memory it was/is sensational sounding. Sure is impressive to get all that hardware in such a cock of a bay, tips hat.

Epic.. hmm find Troy trapeniers (sp!) purpose built salt flat mopar with the custom dart 4 pot block eeeeppppppppppiiicccccccc haha.

[Pommy]

dammit cant find the vid, wanna hear that thing!

[Colza]

Another interesting one.

This thing hit 700+ AWhp before it was eventually passed on.

Running 40psi+ with a custom supercharger and a Holset HX50 and making full boost at 4500rpm

He was aiming to get it into the 9's but only ever got low 10's i think. It had trouble with rod bearings.

Thread there, very long, and unfortunately most pictures broken.

Which is pretty common with FI, exacerbated with an SC. Kinda another reason to avoid it but to a point I'm sure you could build around it?

These are pretty cool setups though, could be a good thread to make perhaps...

Well...wheres the pics??

Sorry for digging up an old thread, but only just joined up in here recently and stumbled accross this one. As Troy said, I'm currently building a twincharged SR20de, which was supposed to be finished back in May, but starting from scratch with only two of us on the build, after work and on weekends, doing everything ourselves (except the custom pulleys), 4months just wasn't enough build time. So we pulled the plug the night before the meet and got the S14 setup in stead....haven't touched the 15 once since then due to the crappy weather, but hoping to get back into it soon. Using a T3/To4e, Ogura TX12 and EFi Hardware quad throttle bodies.
Heres a couple of pics.

Thats pretty insane! Never seen a setup like that before. Nice Fabrication too

[Horny_Devil]

so by the llooks of it theyre running in parallel? and the SC will be used to spool the turbo then cut off with a clutch of some sort?

more info on how it works would be awesome

[Dezigns]

A mate had a late 80s Nissan March-R - we mocked him when he first got it till we found out it was twin charged from factory.
Was also capable of running silly amounts of boost on factory internals and only weighed 675 kg!
Loads of fun smoking VR4s and RS legacys back in the day! hahaha

Yeah, basically the idea is that the supercharger will be on almost from go, giving us what we wont down low, while also getting the bigger turbo spooled up earlier, ready to take over the top end. The TX12 uses an electronic clutch to engage/disengage and the plan is that it will all be controlled by the ecu. We are using the T3/To4e for now, as we already had the turbo and manifold, (as was originally gonna go on the S14a), but on paper it's looking like we can afford to go a fair bit bigger and still get it spooled up at a decent rpm, due to the supercharger....but at this stage it's still all just on paper, as we got lazy and havent even pulled the cover off once in the last 3 and half months, but warmer weathers coming, so will get into it soon enough.
A couple of better pics.



haha, the good old Nissan March SuperTurbo!! I am so trying to track one of those original badges down, tochuck on the S15 when it's finished.

just wonder did you make your own pulley that drive the supercharger? or you get someone else to make it? I have a plan of supercharing my car so would like to know more info on pulley and pulley size.

Due to the time restraints we had at the time, we calculated & did the design drawings for the crank pulley (and also the power steering pulley, as was required in this build), but had someone else do the actual machining of it and cut out the keyway. The design and size of the pulley, will all depend on things like, how much boost you are wanting to run vs the size of the existing supercharger pulley, the placement of the supercharger itself, i.e...does it line up with current crank pulley, or sit out past/back behind it, etc....
Ideally, if you can find a supercharger on which you can change the pulley sizes, it will probably be cheaper, as it wont be as large or as detailed to have one custom made (from memory I think it cost $1600 for our crank and power steering pulleys), or even better if you can find one that is already the size you want and can be mounted inline with your factory crank pulley.

The build we are doing is probably a bit extreme in the amount of custom fab work we have done, but on the day we started, we said it had to be different and look the part, so once we starting cutting holes in the engine bay, ditching brake boosters, clutch masters etc...there really was no turning back

Hey Abnrml,

Thanks for the pics and reply! My setup will be similar to
http://www.automotivehelper.com/topic24983.htm

Got a SC14 from toyota which is going to sit in front of the alternator (prelude h22a)
so the crank pulley will run the supercharger with alternator pulley as tensioner.
The Sc14 got an electromagnetic clutch so i dont think i want to replace it with somethign else. Thanks for the sharing i will definitely keep my eye on this thread.

Cheers

Mike

[Abnrml]

No worries Mike, heres a link to the full write up on what we have done so far http://www.nissansilvia.co.nz/nuke/m...er=asc&start=0 but it's spread across about 20 odd pages

Dam!! I haven't really played with one of those models of prelude, but from those pics, it looks like a mish! Be sure to post up some pics fo r us to follow as you progress with the build.
Yeah, definately hold on to the electromagnetic clutch, then you have the luxury of turning it off when you want, haha. We also have one on the Ogura TX12, we need it with the twin-charge setup and so had to work around it. I have a Toyota bB for my daily/company car, which has a Blitz Supercharger kit bolted onto it, it also runs an electromagnetic clutch, but in the cabin I have a switch with off-low-med-high......and it works!!! Had it on the dyno and with the switch at off, it made 38kw's low was 55kw's and high 75kw's hahaha!

[Cannabis]

I wonder how that Blitz supercharger work lol!
I am saving for engine build at the moment. Almost there.
It just a matter of time and money lol!

would be mean to see a whole build thread from this build...

[Genkei]

seen twin charge EG with Nos

have to find it in one of the old magazine .... it was runnin like 6psi super charge and 8 or 10 psi with turbo and it combines to 16 at full boost....
