Supercharger fed by twin turbos

My tuner Torrie dialing in his GT. He is still playing with the tune so no final numbers yet. http://video.google.com/videoplay?docid=-1368991247906849349

Wow! That is just about the coolest thing I have ever seen. What kind of numbers are anticipated?

Numbers,numbers please!!
Air to air and air/water intercoolers???:dontknow:

 

[Silverback]

That's impressive.

 

[SchuettS]

Thats awesome, be sure to post some numbers!!

 

[Texas Yellow Fever]

That's impressive.

Ussually a 2-stroke diesel will have a blower to start and get the egt's up then use the turbos for the major horse power.

Alot of times it been shown that a blower restricts the air flow of the turbos, hindering performance.

not here though!

Just out of curiosity why didn't he remove the supercharger. Would it act as a bottle neck. Turbos give you way more psi than a supercharger, and wouldn't it restrict the turbos boost from its maximum capacity?. Example turbos boost to 25 psi, but supercharger can only boost lets say for arguement sake 15 psi. Wouldn't the engine only see 15 psi?

All of the fastest GT's I've seen dump the supercharger and the turbos. Go to Heffner's Performance :dontknow:

Well this car made 1089rwhp and 954rwtq before he started this.
This whole deal is not about horsepower. It is about driveability. Read the whole thread and it will give you more of an idea of what he is doing. In it's early stages it is 955rwhp and 915rwtq. As you can see the tq is awesome. Read all about it here. http://www.fordgtforum.com/forums/showthread.php?t=8988

Justin is probably thinking something up right now. It won't be long before someone attemps something like this with either a single or twin turbo setup on one of our trucks. Awesome post Fepony.

Think of it as a two stage air compressor. The blower will compress the air beyond the pressure of the turbos. It's a roots style blower so it's a positive displacement type of blower.

This is correct.

Hmmmm...i wonder what a small turbo would add to my Whipple? These are super efficient. Just think...no lag with s/c lowend torque coupled with turbo highend hp and Whipples constant charge rate. too freaking scary to even think about.

 

[blackviper]

I would be in for something like that. Especially after my motor build sometime this month.

Man that would be off the hook...they need to figure out a way to put a 3.4 Whipple on a Viper motor...wow..then add a turbo and a 250 shot...can we say 9's?

 

[belgiumbarry]

sorry for my stupid question but if it's only a matter of pushing more air in the engine ... can't this be done with SC or turbo alone :dontknow:

the limit is the amount PSI the engine will survive , no ? no matter from were it comes :dontknow:

Yeah there is a limit...but it's a long way away. Forged internals and arp studs are a must. Not really as much shock on an engine as you'd think. Tuning is the key here. Run too much boost/timing and you can't use pump gas. The trick is to make all the hp/tq fast and keep it there throughout the rpm's with solid constant boost.

Actually this isn't even close. That was with a stock Eaton 1.4L s/c. Mine is a 2.3L and the 3.4L is even more massive and efficient. The MINIMUM boost with a stock upper 4" pulley and a stock lower pulley makes and incredible 18# boost. This equates to about 300+rwhp alone. They are killer.
