twincharging a b16b

[thompy.mark]

Just wondering about the possibilities of twincharging a b16b, i.e. a Jackson Racing Supercharger with a turbo as well. Would it be possible/is it worth doing/what sort of numbers would I see?? I really have no idea when it comes to turbos, so recommendations of sizing etc. would be much appreciated

[b16a2]

why woiuld you want to do it?? i dont understand

[Hayce]

Possible, yes.
Worth doing, no.
Numbers, who knows depends on lots of things certainly over 200wkw or throw it away.

[Fabolous]

how about triplecharge? twin turbos and a super charger?

the supercharger gives you mid-range torque, and the turbo kicks in later for top end power

there are a few ways to do it, and most include a bypass of some sort to get around the supercharger when the turbo kicks in. you'll also need a clutched SC so you don't over-spin it at high revs

there's heaps of info on the net... google "twincharged Golf" to get you started

a mate of mine was thinking of doing this to his skyline... did quite a bit of research on it, working out different configurations etc, but surprise surprise, never went through with it

Get the right size turbo from the start and you won't have to worry about that sorta carry on?!

thanks for the info, looks like it's more trouble than its worth! would be cool to get it working, but the time to get a proper manifold made, and all the tuning etc would make it far too expensive i think

[grandell]

some more basic info here: http://en.wikipedia.org/wiki/Twincharger

i'd love to see one done... but yeah, if you don't really know what you're doing you're probably better off just going for a more mild turbo setup instead

Could work quite nicely with a huge turbo, and a sc12 toyota charger. I have seen this done succesfully on a rb20det, and man was it wild.


Basically run the charger off a 12volt switch off the TPS, and turbo runs as per normal. Charger and turbo both merged to 1 pipe then off to intercooler as per normal.

mmm, thought about something along those lines this afternoon. i've got contacts in the states for a lot of the hardware required for the jackson racing s/charger kit with an eaton m45 blower, which i don't believe has a clutch in it (someone correct me if im wrong). would it be possible to punch a hole in the manifold and hook the turbo up to there, bypassing the supercharger?would mean i wouldn't be pushing already compressed air through the supercharger, something that it doesn't like too much.i'd put an intercooler inbetween the turbo and mani too of course. thoughts??

[thompy.mark]

and i'd have to run a shaft or something similar off the crank, and then another belt between the other end of the shaft and the blower right? to compensate for the fact that the b16 turns the opposite way from the toyota

turbo enough said

[miketurb0honda]

yeah i was thinkning of doing this just for cool project something to do ,
it'd be quite fun was gonna use my boost pressure switch on clutched SC so when i hit 1psi boost on turbo my boost pressure switch would cut power to SC so turbo would take over

but really how long does it take for a turbo to spool up if sized correctly and/or a ball bearing turbo?

so really not worth the hassle , but if your got fab skills and lots of time go for it =)

Search around and I think there's a few examples of twin charged Trueno/Levin GT-Z's. Might even be able to find some build thread or tech articles.

I have been doing a bit of hunting around, here's a few things I came across...

The HT link is almost exactly what I had in mind, most of the pictures on the first several pages are no longer hosted, but the author describes how he accomplished it in quite good detail. Am very very tempted to give it a go now

My half brother is almost finished his build on a sr20de Supercharged and turbod in a S15. Its got to be finished for the Silvia club track day on 19th of May i think. Once i have some photos ill post em up for you to have a look. If i get time today ill try find out if he has a build thread somewhere.

[thompy.mark]

that'd be great, thanks

[Trench_Rat]

just google lancia rally cars and see why its worth doing , those things were crazy fast

[WARTYM]

waste of money i say, for the gains & money spent, a properly tuned turbo charged system with tuned headers & all is great but if you got money to burn go for

[Colza]

People never understand these projects.

The main purpose is not because its easy, cheap, or sensible. Yes we all know that a sensibly sized turbo can get you pretty good power with fairly good low end. Yes thats the cheapest way.

But.

Its not cool any more. Useful, but not cool.

The reasons I see for doing this project would be

a) more awesome points than i can possibly comprehend

b) a car that makes huge torque right from the start and then screams and pulls like a turbo Honda from 5000 to redline

c) noone else has one

d) for me I would see this as a challenging engineering problem that would be my motivation if I was considering it (and I have in the past too )

Yes its doable. Yes there are reasons for doing it. No its not going to be cheap.

Dont let these unimaginative people talk you out if it, but for love of god makes sure you know everything on the subject before you buy anything.

Read everything you can about Turbo Hondas till you know them inside out. Find someone to take you for a drive, there are heaps of people on here who would be keen I'm sure.

Read everything you can about Supercharged Hondas till you know then inside out. I think there is someone on here with a spercharger? Maybe hit them up for info.

Now read everything you can find about twincharged cars. Probably no Hondas kicking about but has has been mentioned, they do exist.

It will be an epic project. But if you only get half way and deicde to drop it, you will end up throwing a heap of money down the drain, so if you do decide to start, make sure you have the knowledge, the funds and the skills or the contacts to get it built.

If you are going to go ahead, dont even bother with the expensive jackson racing shiz, just make up a bracket to bolt the sc12 onto the engine. Its actually a peice of piss to do, but the key thing is to run a huge turbo to allow the engine to flow well and make the power/torque you would expect. In all honesty, its not worth it on a fwd, but if your doing it because you can, then go nuts.

[Hayce]

Why is it so epic? It been done before years ago, couple of levin's and there was a Honda (EG?) kicking around once upon a time too...

Still stand by 1st most, doable yes, worth it no.

[Colza]

While his may not look like this. This is pretty epic

EDIT:
I lie, thats not actually twin charged, just a manifold intercooler. But it could be...

[tarmac-]

That is pritty fuking epic.

[Hayce]

It's nice, very nice but its not epic is it? It's not that far removed from something we've all seen time and time again.

Theres been more epic things at autosalon...
