Z, any chance you can test drive a SS to see how they compare?

Thanks for all the updates so far.

Yeah, got to calibrate the butt dyno..lol

Are you waiting for 100,000 mile power train warranty to run out before the turbo install?

Ha!

If he has a smartphone he could do rough runs with an app to compare.

Max, Just curious. What did the inside of the maf tube look like? Is it just a straight tube or is there something inside it?

Rod1, are you asking me or MaxKamai? This is a picture of my intake and if I recall, it's just straight through. What are you looking for? Somewhere to inject your N2O?

Couple questions. to verify the single turbo gives the V6 454 and twin turbo gives it 750???? Can this be done to a Automatic transmission?

Turbo kit is for either transmission. They are only selling the single for the V6 and the twin for the V8's. The single has the capability of much more boost, it's more limited by what the engine can safely handle.

This single turbo give you like 7 PSI isn't it? and you don't have to upgrade any transmission etc? Since i have LS I think i have to get Z rated tires

Thanks for the quick reply and great videos btw:happyanim:. I was just checking them out. What kind of HP are you getting out of the system?

350 rwhp.

Spoone- if you have an LS, you will be speed limited to 118. You will need Trifecta to turn it off if you plan to exceed that level. Wastegate came with a 7psi. Spring, but during the testing, max boost was just under 5 psi. This was designed for a completely stock motor.

Just remember guys, you wont be able to go much higher then what Z is already at. Start getting up at those boost ranges and thats when fuel management comes in to play and you'll need to do some upgrades to get it to work. The LLT being direct injection is why most companies havent even tried to give us FI yet. Anyways.. i wouldnt go any higher than 6psi unless we see some aftermarket fuel management modifications(injectors, pumps, etc).

Dyno Video
 

In case anyone is interested...

that thing sounds SOOOOOO SICK!!

sooo we are basically making stock l99 power with 5psi??? oh my

z, thanks for the dyno runs and videos.
So far so good; that power output is good considering the psi its running at (roughly 18-20hp per psi?!). Sounds like the key component is what kind of psi can the v6 boost to before running too lean. Is Trifecta making any comments on where boost could be upped to safely on the stock set up? And yes a boost controller is a must.

I would suggest a single stage manual - simple yet effective because it takes alot of variables out of the equation in the event something goes wrong. Also, if the wastegate is adjustable, then you can adjust the wastegate to its 'factory' setting, then adjust your boost controller to the desired psi. All of this will need to be done with an acurate boost gauge of course - thats too bad the autometer isnt working right - I wonder if maybe it just isnt hooked up right. But the gauge will be important to monitor while going through trials with the boost gauge on the street.

I guess I would just see what Trifecta thinks you can safely run boost up to, then get the boost controller and boost gauge working right, do some driving around to get it dialed in, and then maybe back to the dyno to see how everything is sync'ing up.

Lol, yeah I meant you. Not sure why I wrote Max. lol.

Just a note on your Dyno numbers. It is known that a Dynapack reads 8-10% lower than a Dynojet does.

If anyone is interested?:sm0:

Thanks Z!:thumbup:

Was going to mention this, but ROD beat me! lol

Z's and AAC's results match up with standard calcs.

Straight from STS. I suck at reading these things but it looks to be about 400RWHP? Looks like im about to be out 6k. :popcorn:

Thank you Z for getting your car on the dyno and sharing your video and report. I have just a few questions. Is this rough curve something that is typical with a turbo or is this an indicator of some remaining tuning issues?

The car sounds great by the way! :thumbup:

400 rwhp at 8psi on aac right? My memory sucks.
