Those that think I hate or hate on Forced Performance can suck it! I just helped a buddy install his FP Black this weekend; it is a beautiful turbo that really performs! The nipple on the FP 25psi WGA broke off as we were putting together the turbo assembly, so we adapted the stock turbo's WGA to fit for now. A new WGA is on the way from FP, but this car needs a double-pump setup before we will be able to truely turn up the boost and get this thing tuned.

This is a DIRECT before/after comparison, we did some pulls, pulled the car into the garage, swapped the parts, then went back out, adjusted boost and these are teh results. No timing/tuning changes other than those that come along with a MAF-based car. Boost on the stock turbo was about 27-28psi peak, and only about 24-25psi on the black. Peak timing is only about 15-16@7000rpm on the black, so there is a lot of room to grow once there is more fuel in the car IDC=98%@7000rpm.

The tune is originally done by Shane@DB Performance, where it will go back to once all of the parts are in. All I've done is help with the install and verify the tune is safe!

Stay tuned for actual dyno numbers on DB Performance's Dyno Dynamics once we get everything sorted out!

 

That stock turbo isn't making much power for 27-28 psi on e85... I guess if its not running much timing then it would explain it.

Stock IC still?

 

Ebay FMIC. Ya car had bad phantom knock so car never saw full potential on E85. Thus being the reason stock turbo only made 338 whp on E85. To explain it better car was running E85 but was more on pump gas tune. As in timing was not much.

 

looks good scheides. thanks for the comparo! Looks like the black is "legit". Nice #'s on low boost. Lookin forward to the finished results... Seems to be holding boost fine w/ the stock wastegate. Nice flat tq curve, or line if u will. lol Im sure it'll do a bit better w/ the upgrade!

 

wow loss less than 1k rpm on spool? That is very interesting...

 

Yea, this turbo is legit. The hta82 wheel is beefy!

Trevor did me the honor of letting me drive his car after we were done with the tests above, and compared to my car w/ the BBK, this car w/ the Black seems quite a bit more doggy in the 2500-3800rpm range when cruising around, gentle to medium acceleration. When trying to get on it in these areas, I feel the BBK provides the car with more beef...the black really doesn't wanna do much until it is firmly over 4000rpm, closer to 4500. Up top, this car feels about as powerful as my car does with the BBK, and the graphs above support this feeling. However, this car has more in it, so hopefully once its fully tuned I can have another go with it for a better a-b review...maybe we can get a video comparo at some point to

 

good job! looking forward to the dyno.

 

Nice results.

I don't understand what you mean when saying that the peak timing is only 15-16* so there is a room to grow when you have more fuel... why don't you reach for mbt at the current boost? and how does the 15-16* tell you that there is more room?


Tks

 

depending on your afr, you can add fuel to cool the intake charge and therefore increase your knock threshold a little...

 

Very nice graph

 

Logging boost at all? That would be a nice overlay

the black is quite a turbo...looking forward to the "new results" once you turn up the wick

 

I have a A/B comparo on the BBK full and the FP Black both on Mike AWD's car. Both unit's currently have their ET and MPH record held on this car, so it seems like a pretty good comparison to make. Neither turbo has ever run better than it has on this particular car. These pulls were made a few days apart, both set on "KILL" obviously, as the record setting performance would indicate. Scheides is right, there is a measurable difference in the spool up of the BBK Full and the FP Black turbo. Look carefully at the 3000rpm to 3700rpm section of the graph. It isnt realistic to say that either turbocharger can perform any better than it is shown to perform in this graph, this is the bottom of the well for either unit in my opinion, perhaps a little over the edge honestly.

 

Scheides, Sweet work on that car! Your results look great, really sorry about the shipping damage on the nipple on that other job the other day Wish I could hand deliver each and everyone of these little babies!

 

Shane@DB Performance did the tune on the stock turbo; this car had an aweful rattle in the stock TOB and a ton of false knock, so it is a pretty conservative tune, especially for E85. I was merely logging the car and making sure it was safe to boost, I literally did *zero* tuning, this is a direct before/after bolt-in comparo, simple as that. No not all is equal, but it is what it is, and all the facts are there.

Stock MAP sensor on this car, and like I said above, I did zero tuning except dial in the MBC to about 25.

Two things. One, that is on a 2.4L car, so I think some of the differences in the 3000-3700rpm range are kind of masked/helped by that. I'm really not talking about WOT performance when I talk about driveability in that range, I'm talking about on/off the gas, part throttle acceleration, cruising on the freeway, merging (gently) with traffic, and putting around on surface streets. The black absolutely felt a bit doggy compared to my BBK. Maybe some tuning will help that? I'll get back to you and post secondary comments, I promise!

I was just helping a buddy, car modding is a hobby for me, I'm in IT by trade. There were 3-4 others helping that day, including my buddy Rosey who took my wife and his fiance out to lunch (to get them out of our hair/keep whineyness down)
