I wouldnt go into numbers there, except if you know whatk ind of core you have in you hands. I have seen an Eclipse GS with a 16G turbo ( the same one as ZPI are using on their their and and turbo kits) running 5.5 PSI and having 260-280 whp. Even thou there are a lot of things that depend on each other. But back to the topic i would start talking about tiwn charged tc when i see some tc's ectualy turbo charged and super charged and we know what we are dealing with.

 

a centrifugal supercharger type(i.e. vortech) and a turbo would be a tight fit or it might not even fit at all. if you were to twin charge the motor, most people would do a eaton style supercharger(i.e. jackson racing, replaces the stock intake manifold) and a turbo.

here is a old pic of a RB26DETT

 

THAT is one gorgeously beautiful engine!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

Agreed!

 

The only point in sequentially mounting compressors is to use one to make up for the loss of compression from the other. i.e. On a big turbo, turbo spool takes longer to generate compression and thus turbo lag. You could use a supercharger to help out with the additional compression while the turbo is spooling, but when it finally generates it's compression then you have to compressors and only need one. (Two compressors eating HP when not needed) You would use a variable compression valve to release the extra compression and keep you from popping the motor. One little supercharger and a turbo would work but in the end parasitic loss is going to catch up and you are going to be producing alot of wasted compression. Very expensive to make up for a little turbo lag.

 

I was using the numbers because they were simple and proved a point. I wasnsn't actually saying that someone was going to shove 30 psi into a tc. That would be lunacy.

 

whoa...look at that thing

 

That engine is a piece of ART.

 

The main advantage IMO would come from using two turbos, one smaller and one larger, to provide more constant acceleration under higher boost. Using two turbos opens up a few more options in placement. The piping and hardware would be tough to pack in there... but it may not be impossible. But it would definitely be a large project!

 

Twin turbos on an inline 4 is ridiculous... They simply aren't as effective on inline engines as a single, properly sized turbo. Why is it that all the Supra guys making real power replace the factory twin turbo setup with a single turbo? Because a single, properly sized turbocharger will start spooling at low rpm's and continue making power to redline. A good example is the 14b on the 1st gen DSM's.

If anyone did this it would be for show and not practicality.

 

of course a single turbo on the I4 for the tC would be smarter, but this thread is about twin-charging, and thats why we are all talking about twin _____chargers

 

you're all wasting your time because it's retarded.

 

I never said it was practical, just speaking to the justification of running twin charging and whether or not it would fit under the hood of a tC.

 

Its just a simple discussion, and no one really said they wanted to try it. Stop trying to turn it into an "I know more about such and such than you" conversation. I know plenty about the subject, and would not even try it on a tC. I dont understand why some have to get all bent out of shape over someone elses conversation and start making childish quotes like the one above.

 

Nice

 

practicallity?

Neither a turbo OR supercharger are considered "practical" on their own.

 

well... if the guys who did the mini make a kit for the supercharger turbo set up. i would deff think abuot getting it. just because i can say i have a twin charged engein and i can go poop on an rsx.

 

Not only would it poop on most cars out there, but the setup would look F'n awesome, i would love to have it.

 

It's a great setup.

 

very well said, BUT it would look cool , lol. No actually it is a pretty good idea in theory, you use a LARGE turbo, so that you move ALOT of air at low boost levels, a turbo this large would normally be very "lazy" to spool, but with the SC "mechanically" cramming air into the engine lag wouldnt be an issue, and by using a big turbo, realize that a large turbo at say 10psi will be moving alot more air than a small turbo at the same boost level and only making a few lbs of boost, the turbo would be barely working and wouldnt be heating the charge hardly at all, and the turbo would all but make up for the parasitic loss of the SC, by putting say 10 psi and a couple hundred CFM of + pressure into the - side of the SC, would make it alot easier for the engine to turn, b ut then again you would have to buy 2 compressers, whenm one "properly sized on would work just fine, there I go blabing again lol
