Damn I thought there where four wheels in a turbo. One for each cylinder. :P

 

No no, its TWIN-scroll so you need 8 wheels.

 

An Evo is really 6 wheel drive you could say. Lulz

 

Glad to see the OP trying out the EF4 it should provide great results for what you are doing its definatly aimed at drag racing and high HP numbers and should provide you with just that.
In a direct comparison to a JB black it should be the best option for you, Look at Svens example he switched from a black to EF4 and has been much happier.

94AWD every time i see you post about an EF4 you rip it apart because its not an FP green, get a clue dude.

 

 

Sorry to bring back, but does anyone have anymore results between the 2?

Im trying to decide between the bb black and the ef4. Im shooting for around 650-700whp. it will be on a 2.3 stroker with kelford 280's

 

I have not seen any back-to-back tests with these turbos. They are both able to make 650whp. The EF4 is a tad larger. I believe about 35-40+ PSI will get you there, my friend. But to make that power easier, you might want to look for a nice T3 set up. If you take a look at the EF TURBO RESULTS thread, you can see what the EF4 has done. I am not sure if there is a similar thread for the FP Black.

By the way, I am actually thinking about selling my EF4 for a smaller turbo if you are interested.

 

FP Black FTW!

 

Ill keep that in mind, if i stay with a stock frame turbo. I was also looking at the ets twin scroll kit with the pte 6466 turbo

 

Why not have the best of both worlds

 

Has the op ever gotten a turbo and posted results? What is the most powerful an EF4 has made? What's the best ET with one? Everyone says it's bigger than a Black but I have yet to see that. Am I missing something?

 

From what i have gathered the EF4 has a better compressor wheel design and its blades are taller making it bigger.. if i remember Correctly the TGP Evo made 612hp on a mustang dyno and ran a 9.92 sec 1/4 Mile. IMPO the only down fall to the EF4 is its a JB turbo

 

Just curious is this still a downfall considering the FP Black has been reported oil slinging all over the place? Trying to decide on a new turbo, so been reading thru some threads. Seems FP Black BB is being reported as unreliable.

 

The FP black is a very well designed turbo. The amount of people giving negative feedback on the FP Black is by far less than the positive feedback.

There must be well over 20 cars I can think of that are running 550+whp on FP Blacks without any issues.

But anyway, the FP stock frame turbos (BB) are currently unavailable, so the only option at the moment would be a journal bearing design, unless obviously if you purchase a used BB FP Black.

 

I would like to see results from Svendiesel or BigDaddyCain. I am also confused about everyone saying the EF4 makes more power. I haven't seen a 700+whp Dyno of an EF4. Is there one?
