here is a copmound turbo on a lnf https://www.cobaltss.net/forums/show...ight=lipsticks

 

Do Twin GT15's or GT20's lol

 

So "compound turbo" is the term I was looking for! lol. Twin turbo implies 2 the same.

 

the blower stops working after a certain rpm? right?, so the turbo outlet runs through the supercharger? if this is true wouldn't the sc gears limit the potential after a certain rpm?

 

sex.

 

That **** is wild, I would love to do a twin charge setup and keep the sc I love the sc lol

 

makes sense thanks boss

 

It's a whale *****

 

i would like to know how they bypass the sc? do they use a different actuator? so the sc allways is making boost till a certain rpm?

 

I know ZZP might have changed the setup to a metal pipe for the intake recently, idk, but my buddy was their first twincharge customer about 2 years ago and back then everyone made comments about the rubber tube intake, but ZZP said they tested a 3 inch metal intake on the dyno and the 4 inch flex rubber intake and picked up 15-18 whp with the 4" rubber intake if i remember correctly; they chose performance over looks

and im pretty sure my buddies was a full 3" from the turbo back...are you sure his is 2.5"?

there are 2 boost controllers, the one on the blower controls when the bypass valve opens at a certain boost level
that is how the setup was on my buddies so unless they changed it i would imagine its relatively the same

blower stops making boost at whatever setting you have the boost controller on the blower set at, then the bypass valve opens and its just free spinning and it is more restrictive than what an intake manifold for a straight turbo setup would be but its not that restrictive....

i mean you tell me if 406whp 372wtq is good enough or not...with no lag

so yes, its somewhat restrictive but not to the point where its ridiculous

Um yes...it does lol i drove one, instant power and making all 23 psi by around 3 grand all the way out to 7...pulled like a dream; amazing powerband

 

^Thanks for the info! Def worded it better then I LOL!

 

you like my name for it huh?

 

No problem, i have a good amount of experience with the twincharge and i saw its ups and downs when it was running great and when it had its problems, and driving it was a shitload of fun too lol

Keep tweeking with the tune and keep us posted because im curious to see how it will drive with your tune vs ZZPs...because, well, theres wasnt the best and thats all i will say lol

 

I just bought a S/C for my other car (03 Matrix-Turbo) so I can twincharge that car. I have a 60 trim turbo on the thing so the s/c on it will be perfect for my lag situation Ill post some pics of that thing when it's done too.

 

 

My buddies was a 57mm extended tip so it was similar in size for the twincharge setup...the blower will make that 60 trim spool like its a 30 trim

Should be a fun project keep us posted

 

you guys do realize that trim isn't the size of the turbo, but rather the relation of the size of the inducer to the exducer right?

 

Im not even going to act like im a turbo expert, cuz im not lol
I just use the trim and a/r as a reference to get a general idea of how big the turbo is

 

It's a T3/T4, .63 A/R, 60 Trim. To be specific lol.

 

Very Sweet.

 

The new kit only uses one boost controller.

How does ZZP control the SC boost in the tune? Do they 0 out the Boost Reduction/Launch control table so the SC bypass valves opens up after 4k?

 

oh i see...well idk how they have it set up now then, the 2 boost controllers seemed to work nicely

 

Exactly! 4k its still holding ok but right after it tapers to 0 by 5k. (tapers quickly)

 

So did you run into any boost spike when the SC was boosting and the turbo was boosting at the same time? IE compounded setup.

 

they stop using the supercharger boost controller becuase people would mess with it and have it bypass to late causing it to compond instead of bypass and cause issues with to much and blow things .
