: Is it possible to use both the Magnacharger MP1900 Supercharger and APS Twin Turbo?

I am just really curious if it is possible. If so it would be an insane ride. Would cost a lot but it would be insane..

-Probably going to get flamed for this..

I don't see why it wouldn't be possible, aside from having to fabricate a few special parts. I don't know why you'd want to do it, considering you can just up the boost with the MP1900 or the APS setup beyond their stock settings.

it's possible, there are currently many mustangs running turbo's and superchargers simultaneously

Wow, just wow.

That would be a fantastic test of the trans.

Hellion Cobra is one of them. Makes over 1000hp.

yes... do a search for dual charge on google.
The advantges is that you get the low end grunt of the supercharger and the top end of the turbos..

You would need to detune both systems to where they only put out a combined of I dunno 10-12 PSI. You will need a hell of a tuner and it will cost an ton.

But it will work and if you can get it to operate smoothly it will be sick.

An thing is possible , but what would be the point?

A roots has loads of low-end grunt (max torque at 1500-2000 RPM) but runs out of steam on the high-end of the RPM band. Larger turbos don't come on until 3500-4000 RPM, but pull like a freight train, increasing all the way to redline. A combination of the two would be interesting.

To really do this right you would need a bullet-proof, forged-everything engine, perhaps in an LSX block (http://images.gmhightechperformance.com/tech/0702gm_03_z+lsx+.jpg). Otherwise you would be scattering engine pieces very quickly. Then of course you would have to contend with the rest of the drivetrain like transmission, driveshaft, differential, axles, etc.

It would be great if someone had an extra $50K or so hanging around to do this and report back the results.

Do you want a reliable street car ,or a drag car ? That is what you are looking at . This car will run 11s reliably!

I know. I have a Hellion Turbosytem on my Cobra.

haha you have to say that with your best Kevin Garnet voice:D
Any thing is possibleeeeeeee!!!!!! haha sorry my bad



but really back to the topic, there has to be an easier way to get silly amounts of horse power in a more sane way right

Sorry, this would be a complete waste of money. The only proper application for twin-charging would be on small displacement engine, and even then it's almost never done. And no, the results would not be especially impressive either. A proper sized twin turbo OR twin screw system alone with the proper supporting mods can easily make 1000whp+ on a 6L V8.

The new powerstroke is esetially twin charged, though it is two different turbos...

I don't think money was a criterion put forth by the OP. And 'proper' sounds like an individual judgment on the idea, which doesn't negate the possibility that it could work, and work well if engineered properly.

While 1000+HP applications are certainly available on a turbo setup, those applications have extremely narrow powerbands that start (optimistically) at 4500 RPM and go to maybe 7000 RPM, which make it useless on the street.

Likewise, to get a roots to put out 1KHP you would end up having to look out your window to see around the blower.

1000+hp on the street is useless regardless of where the power band exists. You can also get a proper turbo setup that'll make 1000+hp on a decently sized V8, that'll spool MUCH faster then 4500rpm. Either way, your point is valid. That power is useless :)

That's a good point, but I would argue that this setup is really less than ideal. The reason Ford did this was because of the huge problem they had with the VVT turbos. Also, because of the diesel's low redline and huge air consumption, a parallel-turbo setup like this maintains peak power output while maintaining good driveability characteristics, something that is less of an issue with a large dispacement gas engine.

I respect your opinion. However, coming from the Subaru world (2.5L MAX), a 4500-7000 rpm powerband would be wonderful on an engine making 1000whp! People modding those engines would be thrilled with a powerband like that even if peak output was only 600whp! So I would say that this powerband would be far from useless on the street, not to mention you'd still have a good amount of NA torque available under the curve, torque that is totally non existent in that range on a smaller, low comp 4 cylinder.

Also, while a roots blower may have a problem with those power levels, a more efficient Lysholm compressor should be able to support 1000 whp without being THAT huge, though packaging would be an issue.

But realistically, how much power can we put to the ground with the G8 without tubbing? I'm sure it's far less than 1000 hp.

You are right, it could work and work well (others have done it), and I guess the concept is not entirely worthless, but how many supercars, even $1,000,000+ cars (where money is no issue) do you see twin-charged? There are many objective reasons that make it a poor choice. I guess that's my point :).

Modding cars IS useless and wasteful, but I'm sure torching the tires with only a touch of throttle would be a a lot of fun. :driving:

Three friends of mine have 1000rwhp cars (well, high 900's). Two of them are turbocharged, one supercharged. The two turbocharged cars have the boost turned WAY down on the street, because the cars are undrivable. You come into boost and the rear end is "Disney on Ice". The supercharged car, well... He just has a death wish.

Its cool as all hell, but anything beyond 600rwhp is just unusable (meaning, you can't drive the damn thing).

Unless of course you're just building a car that smolders tires in 10 seconds. Very effective and expensive.

Well, that was a waste of 5 min. out of my already limited life span. Why go to the trouble with those conditions in a 30 mph zone???

must be.

1400+ whp TT car. and its driveable. and comfortable to drvie to boot. watch any of the videos and see what that much hp is used for on the street!!!!!! lol
