Turbo a supercharger?

[kickertu]

I have been thinking alot about it (not that i am going to do it)
But do you think it would be possible to turbo a supercharged car? it would be a biotch to get tuned, but if you did, that would be MAD POWER!!!!!  


what do you think?

[Kreator]

possible, but a waste of money. It's gonna be an equivalent of a sequential turbo. And i don't think it's gonna give you mad power. It's just gonna give you power through all rpms.

Yep, some rally cars used this setup. &nbsp;Supercharger to give low end power, turbo charger to give top end. &nbsp;They are not used at the same time. &nbsp;I wish I still had a picture, it was really cool looking <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/thumbs-up.gif" border="0" valign="absmiddle" alt=':thumbsup:'>

HKS also made a version I believe. It was called a twincharger. Recently the setup was created in the Meguires acura integra, which was outline in a super street or an scc about a year ago, but the kit was originally built primarily for the MR2.

Thewholefnshow beat me to it-- I was going to say (and still will, dammit!!<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/sly.gif" border="0" valign="absmiddle" alt=':sly:'> ) that this twin-charged system was built mostly on MR2s, though I'm sure it's been put on a couple of other cars. It's really expensive, and will require a lot of fabrication.
It's basically a sequential twin turbo setup where the smaller turbo is replaced with a supercharger. &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/thumbs-up.gif" border="0" valign="absmiddle" alt=':thumbsup:'>

Hard to see exactly how, but this person's doing it with an SR20DET...

I'll try to find the picture I used to have of a supercharged rb26dett. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/crazy.gif" border="0" valign="absmiddle" alt=':crazy:'>

This what you're thinking of?

yeah thats it.

[wpayne]

Hey, yeah, I've seen it done on a 4AG-E engine on a Levin, also known as a Corolla GT-S over here. It was a sequential setup, and yes, as others have said above, it's called twin-charging.

How about turboing a turbo. &nbsp;One smaller turbo spooling a bigger turbo. &nbsp;Now here's a twin turbo setup for 4 cylinder motors. &nbsp;Hey, it works for pull tractors. &nbsp;

Umm... that is a sequential turbo setup.

On a different note, you could, in theory, extend the impeller shaft of a standard turbo charger, and attach a one-way bearing on the shaft. &nbsp;Somehow it would probable have to be custom, to withstand severe heat, and need it's own oil supply. &nbsp;
The theory behind this is that when the engine spins, it tuns the "locked" side of the bearing, since it would be attached to a pully. &nbsp;This should help out the spool-up time. &nbsp;Then, as the exhaust gasses spool the turbo, the bearing would turn in it's "unlocked" direction, and would spin freely.

If someone needed faster spool, this would be the cheapest way.
Anyway... Drag Racing on Modern Marvels are on... so I'm gonna watch it. &nbsp;And they said "Rice Rockets".

That Norwood Teg' &nbsp;with twin turbo is crazy. &nbsp;4.1 liter solid aluminum block 4 with Nos. &nbsp;He's saying 4000 horsepower but only 250 mph, Sh*t wouldnt 300 be more like it. &nbsp; &nbsp; Anyway &nbsp;Group B rally Lancia Delta S4 &nbsp;the most " infamous " twin charged car. &nbsp; &nbsp; <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/sad.gif" border="0" valign="absmiddle" alt=':('>

Just on a side note, isn't there a problem with supercharging a turbo engine?? &nbsp;b/c don't turbos like high revs, and superchargers don't like high revs?? &nbsp;Just wondering...

[Kreator]

That's exactly the point. You use the supercharger at low rpms and turbo at high rpms.

Haha... "Like" and "don't like" ... =D You have much reading to do, little one...
I learnt/read most of my turbo info on http://www.howstuffworks.com , and I suggest you do, too. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/thumbs-up.gif" border="0" valign="absmiddle" alt=':thumbsup:'>

It's not that all turbochargers LIKE high revs, I'll tell you now that the turbocharger on my VW GTi DOESN'T like high revs. It's fully spooled by ~2,000 rpm... it's called a small turbo.
Big turbos (that you'll read about in magazines), though, "like" high revs because that's the only time that there's enough exhaust gas to spin the (huge) turbo.

[flipboi13]

I KNOW HOW TURBOS WORK OK? &nbsp;I was just interested how they overcome the problem. &nbsp;If you have too small a turbo, then I don't know if it would be noticeable with the supercharger. &nbsp;Things change when you have both of them at the same time. &nbsp;I was just wondering geez

[flipboi13]

I'm not a fucking ricerboy or anything like that, I'm sorry if i'm not the god of knowledge on turbo engines like you. I've had plenty of experience with disassembling engines and tech work, but I guess i'm an idiot because I DONT KNOW SHIT ABOUT TURBOS

i don't think the driveshaft would get it spinning fast enough to be effective, it would still be a turbo outside of its efficiency range. &nbsp;Turbos spin so nice and fast because of the expansion of the exhaust gasses...

maybe with some decent pulley work you could set it up... be a bitch to fit in an engine bay tho i'd assume.

I meant well (notice the "thumbsup") in directing you to howstuffworks. It's a very good site with a lot of good information. Your choice of words didn't suggest confidence regarding the topic, and it seemed like you needed some clearing up on how they (turbo/super chargers) worked.
