has anbody ran a twin charging system in here? like running a turbo into a supercharge of running one turbo into another?

Ooh, I'd like to hear if anyone has done this here. This was real big on the 5.0 scene for a while in the mid 90's, but it seemed to sort of die out, and I haven't heard much about it since then. FREE BUMP!

i seen an import at HIN like 3 years back that was both super and turbo charged...i dont remember what car it was

^^ its was a Subaru

and it could work. but the you cant force air more then the supercharger can take. from the turbo....

I always thought it would be neat to run a gt28RS in the front and a 30R or 35R in the rear. "rear mount" for that extra topend

but what about super and turbo charging?

the supercharger is always "boosting" right?
because it makes its power from the engine.

while the turbocharger takes a little bit to spool up so it makes power...

i mean im not a forced induction guru or nothing but i know that much lol.

Do it d00000000d.

why not just run a BB turbo and get faster spool. i fail to see the point.

ya me too.....

its been done and doesnt work to well

like i said, you cant force air through the charger faster, then its gonna produce...

and it makes shit for power....a chick used to own it.....not sure who does now.

It just looks cool, i guess.

well the guy was talking bout some 500 hp with no turbo lag at all and power all the way thru rpm

Rotorex/vortech SC + turbo
you just doubled your air flow at X pressure

Volkswagen has a SC/turbo setup on one of their models.

i'll still smoke you with a single turbo set up!!

hahahahahaha Burner wudnt doubt it ....yea i think this set up wud have lots of potential but i Dont think its really ideal to have both..and as for that v dub i think it was on released in europe

Mr.Burner
04-03-2008, 07:29 PM
ya its a gulf TSI or some shit....... thats for economy crap, not for makin power..

And any "custom" kit for anything just looks cool, sucks for power..

Focker out!

i read somewhere a while back that a rally car ran this setup years back i belive that it was only good for mild amounts of power through all rpm range but trying to get a lot of power out of it was not worth the time or money

the main benefit that i have seen from twin charging is better response. an example of this would be the subaru sti that was twin charged, the picture of its engine bay is above. from what i remember it made 548hp and it could make that same power without the supercharger, but with the supercharger plumbed in before the turbo it was able to condense and speed the air up as it entered the turbo for faster spool and better foot-to-the-floor response.

I think I remember the HKS integra was also compound inducted!!! Correct me if im wrong, its been a while.

i got the idea from one of my dads books that he bought back in the 70's. it had a section on deisels and they were running up top 100psi with a twin set up. thats back in the 70's. then i ran into an artical a couple of years ago about a mini cooper running a gt28rs into the supercharger and thought that was cool. i thought about doiung that with a jackson supercharger since i can get them cheap. but i couldnt figure if the map sensor went off boost or vacum for the fuel map. if it runs on vacum and then you run boost from a turbo it will screaw things up. unless you tap in a map sensor after the supercharger.
then i thought of a small T3/T4 with a rotrex supercharger running into the turbo. :drunk:

it can be done. no problem. if a honda can handle 30pound of boost you can do this

while it can be done, theres not a ton of point. I've seen twin turbo GSR's and they dont make shit for power, although they do look cool :) The limited amount of exhaust gas that comes out of a honda is best used with a single turbo setup.

Although a Roots style blower with a turbo.. well.. haven't seen that on a honda lol

there is the company that does it on subies....

they also designed a newer on than this just dunno where the pic is...

man did you look at that its running just under 45psi and its running a gt35. it should have massive lag.

VW HAS done this with a 1.4 liter engine for european consumption only. it makes 160 flywheel and is supposed to be the shit for the tiny car the euros love. supposedly a 190 hp version is in the works. i'm sure just more boost for the turbo since the sc won't do that.

it uses a clutch for the sc and a dual intake path. at lower rpms, the roots type sc is boosting the engine.

at about 3k, the clutch turns off the sc and the turbo is at full song (it's a tiny turbo, remember this is VW). the intake also switches so that the incoming air doesn't have to go through the sc. cool system, but a lot of work.

burt reynolds is right, a single turbo will smoke it, but if you're in europe, where there's a red light every 100 meters, it would be a monster. which is more important?

Look into first gen MR2's. They came supercharged and quite a few have twin charged them.

there was one in the SCO challenge that was twin charged and bottled. lmao.

im not a fan. just run an properly trimmed turbo and be done with it.

Diesels are doing this now to create retarded boost numbers.. I rode in a dodge 2 weekends ago that had 2 76mm's compounded with propane injection. The fucking trust made 83 psi almost instantly.. going sideways at 60 mph in a 9800lb truck is scary shit.. Cool idea, but it's incredibly hard to tune on gas engines.

Search "Hellion Hellraiser" Should bring up a kit for the 03-04 Cobra's. Uses two 60mm turbos feeding into the stock/aftermarket supercharger. the kit is good for about 1600hp. :clapper:

you guys are confusing twin charged with compound charged.
twin is s/c and turbo, vw does this in europe with a 1.4 that makes 160 flywheel and mega torque. great engine. s/c is on clutch system like a/c and shuts off when turbo has X amount of boost. keep your fingers crossed and we'll get this engine.

sequential is like old rx7 or last gen supra. all exhaust energy goes to one turbo then second. in case of rx7, they were different sized, in supra they were not. bmw's new 3.0 diesel does this too.

compound is where one turbo blows into another. the first is rather small for quick spool, but the second is much bigger. but since it is receiving boost, not atmospheric air, it will boost much quicker. however, you must be careful, this setup will do 80 psi easy, and for a diesel that's high performance. for even a sleeved honda engine, it might be death.

that is what the S/C is for. no lag
