Boosted Performance single turbo results

Boosted Performance · 06-24-2012, 08:05 PM

Well, today was the day we finally got the Boosted Performance twin scroll kit strapped to the dyno for a proper tune. I am sure most of you have seen the build thread and what this kit is all about, so I won’t get in to details about that.

To start with we installed the 8.7psi spring in to the two Tial waste gates, and those yielded some good number with boost falling down to about 7psi by the time we hit 7000rpm. With the waste gates in there, and the drop in boost the car made 456whp. Not too bad at all. Once the springs get hot they loose they soften up a bit, hence the drop in boost.

Luckly (thank to Lee) we had a manual boost controller handy. Plumbed it in (only took about 10 minutes to do since everything is easy to get to) and proceeded to tune for more.

The results speak for themselves, and the tune is nowhere near aggressive. In the graph you can see the boost fall to 8.1psi, so a manual boost controller would be the best way to go. This did the job for now. So we managed to get the 513whp at 9psi, according to the MAP log in the dyno chart.

This was on pump gas, no meth, or any other fancy tricks (race gas) that some use to make a kit look better than it actually is.

The turbo is a Precision 6266 T4, twin scroll, 1.0 a/r turbine, 340lph fuel pump and 750cc Bosch injectors. These are the items that the Stage I kit will come with. So this is what you can expect as far as numbers go.

Those with videos can post them in here as well, but I see that they are already out in the other thread.

I would like to thank Greg and Sebastian from Specialty Z. These guys were great, and very professional. If you are in the L.A area these guys are great and should be considered for all your tuning needs.

My customer decided to go back for some more tuning with an EBC, hoping to keep the boost level even at 9psi. The results are below along with the review of the AEM tru boost controler. Impressive peak hp at 9psi of boost.

Before talking about the results, i would like to point out just how linear the hp/tq curves are as this will be somewhat important.

The hp curve was so linear that peak hp was always towards the top of RPM. So to simulate running 9psi at the top, Greg and Sebz felt it was safe to raise the boost to 12psi in the low/mid range so when the boost tapered off at the higher RPM it would be right where we wanted. Keep in mind that the results simulated were with a drop in boost pressure, not a spike ect...

With that being said after talking to Sebz and Greg, they both felt that with a working boost controller holding steady at 9psi that the car would produce the same results. We will be putting this to the test once I get the EBC situation resolved and get more dyno time. Don't know how fast this will go as I am gone for half of July, but I will work as quickly as I can.

I would like to point out that I am not saying my car is running 9psi, clearly it's up to 12, just simply stating that peak hp was at 9psi and that hopefully in the near future we will not need to crank it to 12 for those results

Again, I would like to thank Gerg and Sebz for their awesome work! I learned a ton while you guys were here and I look forward to next year (if you guys can put up with the late nights

)

Thanks, and what 2.5" exhaust? The down pipe is 3" and not that long, then it goes in to the dual 2.5"...dual The dual 2.5" has 40% more cross sectional area than a 3.0" exhaust.

This thread just might have convinced me to keep the Z for good

Pump gas? Very impressive numbers! Have the IC hidden away and that would make for one bad *** sleeper! Congrats!

Exc results, nice and smooth. But I wouldn't call that 9psi. It's more like 10... It does drop in the top end and that's where our cares make the most power, so if it would have held the 10psi up top this would have yielded close to 525 IMO. Good Job Sasha!

We have an auto that will give a run for your money on 91 OCT LOL .

Good results, Congrats

So, I'm interested but now I have a Question.

You had to install a manual boost controller.

Will the kit come with that part?

If not, what power should we expect from the kit that will be shipped?
