FP Black 1/4 mile update.
Does this car have the same gearing and weight as Project White? I'm just wondering whether the drag results are comparable. I don't feel so bad about having an old tech Red when I see that 138 mph in your signature on the stock ECU, even though my car will probably never hit the strip in any serious way.
By the way, in honor of BLKCarbonEvo making half the posts in every FP Black thread, I think this turbo should be renamed the FP BLKCarbon turbo.

Counter intuitive.......you are entitled to your opinion but seeing as how the car gained nearly 10 whp for each psi of boost I kept feeding it up to 40 psi I'd say your opinion isn't going to get much support. Add to that the fact this turbo makes 20 psi at 3800 rpm and looks like it is still capable of running 9's in a fairly heavy street car and it seems like an ideal turbo to make a LOT of people very happy.
Believe me, I'd rather sell someone at $5400 HTA86 header kit than a $2000 bolt on turbo, fact is this turbo, like the Red and Green have place in the market.
Will this turbo blow up? I doubt it, the Red that was on the car before this was run at 40 psi of boost to, never had a problem. If it does blow up, oh well, it's the price you pay to go fast.
Run it at 22 psi on pump gas if it makes you smile.
BTW, 40+++PSI FTMFW.

I couldn't agree more with this post. A year or so ago 30psi on 93oct was nearly unheard of and thought to be unconventional...inefficient. But now it's proven to be a common and successful thing given the setup is efficient enough to run that way. I've ran my Red @40psi at multiple track outings/dyno tuning sessions and 37psi all day long every day on the street. These turbos are meant to run high boost for high power in a reliable manner. If you don't move ahead with the times and what works be prepared to get left behind. 
if you read anything about turbocharging theory, it's about fitting the turbo to your application; yes this is responsive; but what's the point of this response at the drag strip? there is none, for other types of racing yes this could be ok..but it still brings to mind the fact that to achieve 500whp on this turbo; it needed 40psi. IMHO that is a horrible statistic, especially on pretty much race gas(e85).
This turbo is really not even a jack of all trades, no time attack guy that wants to get 500whp will want to run 40psi, that's just out of the realm of possibility for most. On the street what will this turbo make at even 30psi, from what mr buschur said; probably 400whp? So what is the difference betweeen what the red can do vs this turbo; so far I really see nothing that would say this turbo is a better value for any rhyme or reason. I don't really like the red either though; again..35r or a 30r would be less boost and we know that less boost and less timing=a less knock prone motor and that = a happy motor
40psi is a lot of boost, even to the supra 2jz and nissan rb30 guys; and yes this is probably making the turbo go past supersonic; know way to truly know since FP doesn't release it's numbers, but 40psi has gotta be off the map. One things is for sure, dave buschur builds some great motors; my future buschur motor will never need to see 40psi, I would have a 35r if I needed 500whp; simple. Probably never need more than high 20's psi.
excellent times... you're probably making 600+ on a DJ.
ALL SMILES
Mikey is just jealous because he's got a red. He'll have a Black soon enough. I give him until February.
MOREPSITHEBETTER,
Do you understand the difference between cylinder pressure and boost pressure? Can you tell me what kind of cylinder pressure it takes to make 500whp? Let me know how many bar that is... The amount of boost pressure the car runs is VERY insignificant compared to the amount of cylinder pressure generated. Go ask the guys from GST... they'll agree.

And I too ran my RED at 40 plus psi with zero issues
I'm not going to get into a dyno debate but you keep mentioning 500 at 40 psi like its a bad thing. This is 500? at DB's. I know I made 631(backed up with a 9.50 pass at 145) on a DJ with my red and if the numbers hold true(red-black) thats close to 700 for the black on my car. Not a bad number for a bolt on turbo. You wanna run 20 psi, be my guest. I'll have fun at 40psi...
well for this same reason, your motor could probably easily suffer a very nasty failure at high rpm and high boost(no offense)

This turbo has a 35r size compressor wheel in it, 40 psi is not out of the efficiency of the turbo. Quit blowing smoke out your *** and get with the program, this isn't a Td04.
someone correct me me if i'm wrong but having the turbo set to 40psi for DD shouldnt matter a thing unless your pushing the car on the streets to 40 psi all the time! i mean just taking what i see on a daily basis with my car it spends more time in vac, and doesnt really pass 15psi unless i want her to. so running 40psi on a turbo for the street shouldnt be a problem. your more and likely not going to see the full psi unless you want to.
correct me if i'm wrong.

The point of responsiveness is to make this a great all around turbo for the average guy. A turbo that is still very useable and fun on the street but will still be able to perform at the drag strip from time to time. I'd say they hit the nail on the head.This turbo is really not even a jack of all trades, no time attack guy that wants to get 500whp will want to run 40psi, that's just out of the realm of possibility for most.
