Boosted Performance single turbo results
 

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.

great numbers:tup:

awsome just awsome :tup: . i was scared the 2.5 inch exhaust would hold back the flow, compared to a 3 inch. now all i need is this kit. ...... soon ........ est availability date ?


ps: and once agin. awsome :happydance:

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.

Huskey 94

great numbers!

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

Got to see this thing dyno in person today, was amazing! Looks like I'm not quite done modding yet...:yum:

ment dual sorry

any acceleration vids coming soon from inside and outside of car?

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

Sam

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?

Thanks! I was looking at peak power and what boost pressure I land at if I was to draw a line straight down. Either way, it is solid power, and the car drives just like stock. The tuner said that if we were to maintan 10psi we would get to 530+..but that is just a guess.



Thanks Sam. I am sure there are a lot of faster cars out there than this. This however is just the tip of the iceberg, and the turbo in reality is still sleeping. I am sure you would agree that the billet wheels don't even wake up till 20+ psi.This car is also a DD during the summer, so things were kept conservative, to a degree. The 67mm turbo would have yielded even more power at the same boost level as well. In time I guess, once people start building these engines we will really see this thing shine with the larger turbo and a 1.32a/r housing.





The kit will come with all springs for the wastegates. So, the end user can select whatever combination they wish, to run whatever boost level they desire. The boost controller will ensure that the boost does not fall off a bit at the upper rpm range.






:bowrofl: ....really, so people can't make a joke anymore? If one finds that offensive then I feel sorry for you.

Instead of feeling sorry for insulting half of the potential 370Z community, just understand that there are 7AT's boosted as well with similar numbers, and not promoting a perception of inferiority would be a good idea. :ugh2:

one thing is for sure, that with this kit youll be baking plenty of tires :eekdance:

As the exhaust back pressure increases (with RPM's) the plunger at the bottom of the waste gate is exposed to it. This works with the spring and opens the plunger/waste gate more as RPM's rise. The spring in the waste gate also gets hotter as exhaust temperatures rise, increasing spring elasticity, making it easier to compress.

This is why we have the boost controllers. As the timing was increased the drop in boost increased a bit as well. This is just the nature of a turbo system. The boost controller also helps in spooling the turbo a bit faster. You will find that most cars out there with a turbo system do have a boost controller of some sort.

Thanks for the info. :tiphat:

It was a joke man, not an insult. Are people that uptight these days? At no point did I say that this is an inferior kit either..I just stated the advantages over some other systems. Let's not get crazy here.

:bowrofl:

I appreciate it..:tup:

Back on topic. These numbers are GREAT. Congrats.

It's not that people are uptight, it's just why even mention the 'type of people' who buy one option vs the other when it doesn't bear any influence on your kit, or it's potential numbers. (Which were very good)

It's not that you were saying one kit was inferior, it was the statement about AT drivers being more interested in baking rather than turbo's... Whether or not you meant to insult them, like it was said, it's the internet, perception is reality. If someone perceives you insulted them, the damage is already done..

Wow, a lot of sensitive people out there...

I saw this build in action at different points and then again at the dyno. The smooth spool, solid power and a real good tune made this the kit for a lot of garage mechanics to self install and reliably create gobs of power that won't blow your bankroll, or engine.

Awesome work to all the innovators out there and special "hats off" to James and Sasha for enduring all the trials and tribulations of bringing something totally unique to our community!

I highly recommend this kit to any DIY'er with a basic toolbox and a free weekend...

just my :twocents:

Great numbers from the kit! :tup:

I do think people are overreacting a bit. I drive a 7AT and I actually thought it was pretty funny :icon17:

I am glad that at at least one person can see it as a joke, and build on it..:tup:


Well, I don't think it is fair to compare it to the supercharger kits, so that is off the list right off the bat. The torque with the supercharger kits usually stays lower, and the area under the curve is also lower on average.

The "other" single turbo kit is just too far from the engine, spool is also slower as a result, and as a result power is limited.

TT kits are great, and do provide ample of potential for a stock or built block. This has been proven and there is no arguing that. The advantage of this kit over that is that it is very easy to install and take half the time (cost). It is also easy to maintain because all parts are easily accessible.

I changed the turbine housing on this kit couple of days ago to a larger one (to allow for better flow) and even with the hot exhaust it took only about an hour. With things cold, it would be about half that. This for example is the only thing one would have to upgrade if one is to build the engine and go for more power. Wastegates are also easy to get to and the springs can be changed without ever removing them from the car.

The kit also comes with an oil cooler, larger than competition standard injectors (750cc vs 600cc), and larger than competition fuel pump (340lph vs. 255lph)

Disadvantages....at this point a customer can only use the F.I exhaust because this is what the down pipe was built to work with. In time others will come available. The kit does not fit the a/t transmission car. Other than that, I can't think of anything else. Some may consider the removal of the crash bar a disadvantage as well. The FMIC weighs more than the crash bar, so it is a substantial amount of aluminium there.


I should also mention that you don't have to remove the washer fluid reservoir, there is nothing to drill, nothing to tap. It really is a true bolt on kit.


Can you please move on. Everybody has gotten over it except you. I am not sure if you are going to be at a disadvantage if I lose a couple of customers....last time I checked there is only one person on the payrol here...and that is me. If it brings my business down...I guess I will just have to live with it.

:tup:


To the rest...thank you for the support. I am looking forward to working with a lot of you on a kit taliored to your needs. Should have a lot of happy customers once these start moving out the door.

Sasha, thank you for bringing a well put together, somewhat of an easy install, single turbo option to the 370Z community. Had your kit been around a year ago, I would still own my 370Z.

I also want to point out that people should not be scared of purchasing this kit without owning an FI exhaust. Any exhaust shop can fab something from any exhaust to the kit's 3" downpipe for $50-200.

Great guys and great kit , unreal power. Sasha was great meeting you as well , I owe you a case of beer.

Very true, and this is why I made the down pipe as long as possible before spliting in to a reverse Y-pipe. So yes, an exhasut shop would be able to mate this up to any exhaust in no time.


Good to meet you as well...don't worry about the beer....not much of a drinker here.

The is Jmac88 posting under Ed's account.

Firstly to Sasha's defense he has stated in the other progress post that he will work on an auto design if he can get his hands on one. Anyone who was seriously considering the kit would know this. It was a joke and while I agree he should not have said not because it wasn't funny but because people get but hurt over the dumbest things. To people with other kits, I am glad you are happy with your kits as am I. I would kindly ask that you refrain from more negative posts in the threads. It's just as unclassy as a bad joke.

Now for the interesting news. I am trying to get back on the dyno tonight if all goes well. I bought an ebc this morning to try and level the boost off. We are shooting for 9psi across the board. I am sure the car will make the same power on the "9" psi as it did before if not more. Keeping my fingers crossed that they get time!

oooooo..... I need to get across town ASAP!

Hmmm to far of a commute for me haha

So half price of other kits, what are we talking about here 5k?

I think it's 7300 oil cooler included

All off topic posts have been removed!!

Just a reminder to keep it on topic

another visit to clean up off topic posts by staff

Will dealt with a warning of possible temp ban.

Please KEEP IT ON TOPIC.

Thank you & have a nice day :)

How are the oil temps now with its current oil cooler setup? Are there plans for bigger oil coolers in the future as options or is it sufficient enough? Would it also be enough for track use?

Still haven't hit high temps in Alberta. WIll have to update this thread once James gets some driving time on the system...

Larger oil cooler would be no problem at all, I doubt that it will be needed though.

Thanks for all the pm's and support as well everyone. Nice to see great support of a new product.

Can't wait to get these built and out the door.

I pm'd you about possible HR application!

Really like the placement of the turbo compared to an STS, or normal engine bay setups. I'm sure it doesn't get as hot, or get too laggy. Either way looking for more vids...flybys!
