New ZZP “Big Wheel” Turbo going in this weekend!!!!!

[SUPERDAD3114]

That is a good thought NDarkling although I am not convinced based on how complicated of a piece that is. There is one way to check, if superdad measures up what areas he thinks are bigger we can compare to a stock.

I’ll see what I can come up with this weekend. All I know is I am still astounded at the considerable change in my car. A little longer than normal to hit boost but that’s to be expected with a bigger wheel.

Will have a video up after this weekend. After a week with it on, I have had a ton of fun in it. Great mid to high range power. I would say my next thing coming after clutch and flywheel, e85, and rims and tires will be valve springs. definitely feels like that would help my power above 5500 rpms. After talking with zzp I told them I wanted to port the intake and they just got done doing a dyno showing a before and after the porting and they showed 15 whp gain. I will be doing that this weekend then sending them a log so they can retune afterwards. They said when they tested it they had to up the fuel just a bit. I will get you all a video before I do that so you can see what I am experiencing with what I did after the turbo and then I’ll send another after the intake so that you can see that as well. I’m sure every car is different on the gains shown from porting the intake but hell I will take 5 whp if we’re taking free. Send you all the vids this weekend. I appreciate all of the feedback on this so far

Here is the 1st of 2 videos I promised. This is pre-intake port. Don’t laugh at my excitement okay.... I was happy that I hit under 7... my best about 2 weeks ago was a 6.78 0-60 and my clutch was just starting to go. Now, it’s really hard to take off in the state that it’s in and this run was the best since that time initially after the turbo install which this run clocked in at a 6.82. I feel that after the intake port and a retune after this weekend and a new clutch coming in the next month I feel that sub 6.5 isn’t out of the question. I will continue to keep you all updated as I continue. Again don’t make fun of my excitement. It was just nice to see something under 7 since my clutch issue started 10 days ago. It’s like the minute the turbo went on the clutch lost everything. But I haven’t exactly babied this thing in its young life lol. I have been pretty hard on it pre mods so I feel it’s done good. The link to the video on YouTube is directly below this paragraph.

I didn’t realize how bad the sound was. I am going to try and use my wife’s camera next

Here is a video from last night post porting the intake. It made a noticeable difference.

What are you shifting at? Does it still run out of breath pretty quick on the upper end?

So with 0-60’s my best times come when I am shifting right at 6,000. Post porting of the intake, yes it does help. I wouldn’t go as far to say it helps above 6,000 but it definitely helped me above 5,500. I noticed some definite gains there

I never trust those add-on gauges to tell me the time.
Can’t tell from the 1st video since the speedometer is hiding, but from the 2nd video I timed it at 7.3s (I’m using a video editing program) Do you have a video that shows what you were doing before the turbo install?
Also how much power you’re making before and after the turbo? Have you taken it to a dyno?

 

[Gimpster]

Even better, if you are an HP Tuners owner, post a log of some pulls. I would love to see the airflow data.

Oh I love the age old 0-60 talking points where no one is right and everyone is right all at the same time lol.

I don’t know that I have a video of prior which the speedometer wasn’t hiding lol I just had it at a bad angle which you can tell this time I fixed (which for your knowledge I shift out of 3rd shortly after hitting 60 so it will be somewhere around there) what I can tell you about previous 0-60 times, prior to turbo, is that it was saying 7.1-7.3 depending on the runs.

Also I don’t know I can agree with you as I’m timing it as well and I’m getting anywhere from 6.7-6.9 which even if it’s that I’m still good. And actually you said you can never trust the add on gauges to tell the time. But It’s the same as plugging in your computer to run a log (which I will have for you all considering the next person was asking for one) It is information that is running directly from the cars obd2 to the gauge) just like a log (this is a scanning tool that is in gauge form and for $600 for both gauges and the a pillar, it better be at least close to accurate). I have read here on this forum that you can never be positive of our actual speedometer gauge on our cars because of the delay from what the speed actually is to processing to display on our gauges of the speedometer.

Also as previously stated I am working on getting to a dyno. Kind of hard when you have the work schedule I do lol.

At least I am doing my best to being transparent with you all and show you my progress since the turbo install and then after porting the intake.

I will say this. I’m right under 21 lbs/min on the maf readings 20.5 to 20.7 (close to that) which if big turbo sonic is reading, maybe he can confirm. But it’s something like for every 1lbs of Air, it’s 10hp. So we should figure 200-210whp? Please tell me if I am not right on that because last thing I want is to say something that’s incorrect and get blistered for it.

But I am working on dyno to confirm for everyone’s sake.

Now I take the time back. I’m sitting here timing it on my watch at 6.9 to 7 flat. Do we really think it’s that off? Whether we’re talking about the speedometer or the guages. Could it be that the gauges are doing the car and driver 0-60 times where they aren’t counting the first foot? It’s been 2 tenths difference between posted time and real time. This is what I meant at the start of the last response. 0-60 discussions never end

Theoretically you can make 10hp per 1 lb of air but there are a lot of factors. So when company's say this turbo is good for 330hp. Look at the map and you'll see that max flow is 33lbs.

So one of the things I get annoyed about with BNR is they dont post dyno graphs on their gtx kit on their web page and I havent seen any on this forum. Besides that, their signature says "201whp gtx" and from what others have posted they are at 21.5lbs/min of flow. Not too far off of what is expected.

With my setup I maxed out the maf when I went down to MPFabs a few weeks back. It will only meter to 26.5lbs/min and I hit that at 5,800rpm. I still had 700rpm to go. Lets say I hit 27.5 lbs of flow. The car made 249whp. There are things I am speculating why I didnt make more power.

Prior to all the tuning MPFAB did, I was flowing 25.5lbs/min and with some street tuning by mpfab the first dyno made 230whp. So yeah, I was far off of what was expected. I was probably making 210whp and I was flowing 25.5 lbs. AKA a horrible tune.

Point is, flow its theoretical.

Accelerometer computer timing is bull****

We have never found any computer to be accurate as far as 0-60 or 1/4 mile time. Back when our car was only running low 15s our computers were telling us the 1/4 mile time was mid 12s lol. And as far as im concerned dynos dont give you a true hp either, first off you are doing a pull in 1 gear, with no real life effects or shifting trauma, and if you are changing tune while doing it you are really lost. We have found when changing multiple tune settings it takes quite a while for the ecm to adjust and settle, usually about 4 start and run cycles, or about 20 miles of driving. We do all of our power figuring at the track. We have raced this car every weekend for 3 years, it has 418 passes on it with recorded temp, humidity, baro, desity alt, water grains, elevation, car weight, and fuel type for every single pass. And as far as maf, like big turbo said its a theoretical value, we have maf readings of up to 25.0 with the gtx depending on air filter type but that dont mean ****. We know this car is making at least 235 whp from 1/4 mile time and mph at the weight it is.

I don't have a problem posting GTX numbers.

Here's a customer's dyno sheet before and after the GTX. Both at 21psi, both on 91 octane.

The MAF is an accurate measure of HP AS LONG AS IT HASNT BEEN EDITED. Once you edit the MAF table, it's no longer accurate and you will see higher or lower flow vs. HP.

Nice to see a dyno and I never said you had a problem sharing. Many people have been mislead on how much power your product makes because of your product description and no dyno graph on your website. Thanks for the informative insight on the MAF.

I keep hearing this, but I don’t understand how people are being mislead. How can I make it any clearer?

“BNR's GTX14 is the ultimate in stock-body turbo upgrades. Starting with a BRAND NEW GM 1.4T Turbocharger, and using our proprietary compressor wheel upgrade we are able to achieve much higher power while maintaining driveability and fuel economy. This turbocharger, along with the required injectors and tuning, will take your 1.4T beyond the 200HP mark. While we are able to achieve 175HP on the stock turbo, by 5000RPM it has run out of breath and is down to 150-160HP. With this turbo you will be able to hold 200HP all the way to 6000RPM and beyond, meaning that this turbo produces gains of 50HP AT THE WHEELS over 5000RPM. Compared to stock that is over 75HP and 120TQ gained AT THE WHEELS.

A direct swap with your factory unit, this turbocharger can be installed quickly and without expensive custom piping.”

BNR I just want to say I credit you guys for bringing something more to the sonic market. Most people cant afford a full swap and this is like the final puzzle piece for most people.

Perhaps its the "beyond" part. Like, to infinity and beyond! I have heard from people I wouldn't consider a beginner to modifying cars, that they are making 240whp on 93 w/gtx. Simply post up your graph.

Whoever is claiming to make 240whp on a gtx without some other power adder is full of it. We’ve seen 220whp with meth, and whitesmoke ran the low 13 pass with nitrous and a gtx.

Understood but the point is, your customers are mislead. No hard feelings. Just have never seen a dyno graph from yall. Thanks for sharing.
