DO IT!!! I want to see a legit twin turbo Evo. HTA3076 and HTA3586! Not even sure that would work.

It could be done that way, but they are too close in size IMO. The stock turbo wouldn't be a terrible match for a 3586 though. I'd still recomend bigger on the primary.

 

Norris designs is making that super charger / turbo. The supercharge is on the back side of the motor towards the bottom. he said that if it works out the kits should be about 10K.

they have three vids on their channel, but no engine shots....

 

madmac's evo running hillclimbs
runs a supercharger and turbo 6krpm rev limit (set as a test can rev higher) but there is so much torque he didn't need the revs

A guy on the forums tried this idea. He had a 1500 cc charger with an HX50 turbo. The car did amazingly well until that his tuner didn't have experience and AMS wasn't sure how to handle a setup they didn't build.

I have always thought twin charging would be a good idea. I hate seeing twin charger setups that use a centrifugal and a turbo would much rather see a roots charger.

On the topic of tt setups I say do compound instead sounds little easier and more efficient from what most diesel guys say.

 

Dont worry mac will be reving higher now. He had a bust supercharger that has now been fixed. thing he is dynoing the beast soon cant wait for numbers

 

All i can say is i want 1 no other way to put it or maybe this in front facing tt

 

Madmac's Evo 5 is pure sickness. No lag, massive torque and HP, low back pressure.

 

It will be even better next season. he is going to be rebuilding the motor this winter (3years old now) as well as making some mods to the setup. Should be very intresting once he has finshed.

Oh and he has designed and built tubular subframes front and rear.......

I think that's what he was reffering to to begin with since twin turbo is mostly used people just throw it out there but technically twin turbo is a turbo on each manifold and our cars has one so compound would be the only way to do this.

And ams was going to do it in their top shop challenge but according to modified they dropped the idea because of cost and went with a single turbo.

It can be done. Anything is possible u just need pockets deep enough.

Here's more food for thought how about a twin charged evo? Why have two small turbos like the original op said or a small turbo feeding a larger one. It would be sick to see a supercharger handling everything down low and a huge turbo taking over up top.

 

The AMS setup looks compound at first glance, but was actually sequential. People have compounded turbos and super chargers, but the problem I have with that is that the SCs most people would use for this are pretty inefficient, and compounding it will just compound the inefficiency. But it does work, and people have been happy with the result. One benefit is that since the SC is tied right to the crank shaft, spool up is predictable. In a case like mine with an auto trans, that would be beneficial. The spool up on my small turbo changes with the conditions, which can be somewhat aggravating, but once it spools, it spools the big turbo with no problem and ultiamtely that's the main goal.

 

Why does the posted dyno have hp/tq crossing above 6500rpm? Quite far from 5252....

 

HP and TQ are on different scales. There is also some wheel HP vs engine HP ****ery going on there.
