the second one could be an oil cooler. I've heard of these, they help maintain your engines running cooler, and give the a longer life.

I might be wrong but it makes sense to me, if you run both s/c and turbo, im guessing engine temps are gonna be higher than average.

 

I don't think (besides for looks) that having both would produce anymore power than just having one (unless you had an unbelievable re-mapped ecu). Wouldn't they just cancel each other out? I mean both are sending pressurized air. If the turbo was sending more boost than the s/c, than the s/c wouldnt be compressing the air and if the turbo was sending less than the s/c, than the turbo wouldnt be compressing air.

 

I think it would be a multiplying affect (or I read so in SCC). Such as if you had both turbo and super running 8 psi each (.5 bar, that is about right I think). So outside the everythign at sealevel normal day etc air press is 1 bar then the turbo makes it 1.5 bar (8 psi above or 24 psi) then the supercharger would make it 24 psi to 36 psi. Then thats 20 psi above atmosphere. Sorry if its not 8 psi=.5 bar my internet wont let me search it for some reason.

Thats what I read in SCC.

 

^^^ I see what you are getting at and it made me start to think:

I think it depends on how the boost controller operates. For instance: a wastegate opens when the air going to the turbo is at its set psi. So if the s/c was set at 8 psi and the turbo wastegate was set at 6 then the wastegate would be open whenever the s/c is producing boost so therefore the turbo would only spin to make 6 psi (therefore doing nothing to produce anymore boost).

On the other hand, there may be boost controllers that read the air coming in as "stock (for lack of a better word)" and they would put (lets say 8psi) on top of the current boosted air. For example you have the s/c at 8 psi and then the air gets to the turbo boost controller and it would add an extra 6 psi ontop of the 8. So really it would be like 14psi from the turbo.

Does anybody know if there are boost controllers that operate like this?

 

i just didnt see the point of something like this...why not just have a larger turbo? I think superchargers dont have lag though, thats the only reason why i would see someone doing this....more power off the line then the turbo takes over and you get more power down the strip

 

I recently read an article on the twin charged engine that VW produces in Automotive Engineering. It appears that the Supercharger gives you off the line power where with a turbo setup you would normally have lag of some sort, and once the engine gets spinning to the point where a turbo would be more effective than a supercharger, you get the benefits of a turbo so it seems to offer the best of both worlds, for an increased price of course

 

usually the bigger the turbo, the more useless the car becomes as just a driver, low end is lacking more then a auto accent.......

and superchargers do have a slight lag, its total BS when people claim there is none at all. its just not as bad as a large turbo.

a properly sized turbo for its application will have no noticeable lag, for instance, the 1st gen ford probes hit there full boost, and full 190TQ at 2300-2500 rpm.

 

Our supercharged drag car and hot rods have no lag. They run mostly 4-71and 6-71 BDS superchargers and produce almost maximum torque just off idle.

 

i know its not a hyundai but this has been around a long ass time
