but the potential is there none the less. this is just the answer the question about draggin with the BBK. true there is no real comparasion with both turbos yet but i think the BBK can hold its own.
we really do not know about the E.T.s because no one has posted them yet. how many HTA green cars hit the 130's?
think about it though. i would venture to say that the FP line of turbos are meant for more top end and of course since they are stock turbo based you see midrange gains as well. the BBK was designed for the broader powerband in mind. two totally different mindsets went into creating each turbo. its been said that the BBK was meant for under 30psi applications while the FP green, red and Black all shine very well with high boost levels. just like not all 272 cams are the same. some will net you more top end and some will net you a broader power band.

FP turnaround time sucks. But I would wait 4 hours on pancakes if they were best in the world. If you guys want to be impatient and choose an inferior performing turbo that is certainly your choice. I am still laughing though. Here is what the current data suggests for these turbos:
The Tomie is extremely close to BBK. Here is flow of current turbos. and wheel size.
69mm Tomie, original green.
70mm BBK
73mm HTA Green
Green 47lb/min
Tomie 49lb/min
BBK 50lb/min
HTA Green 54lb/min
Turbos dont make great HP. Good setups do.

Actually I'm having a hard time working out which TD06 RR 11 bladed turbine is which .
From looking at pics it seems the CBRD BBK Full is using the standard TD06 11 bladed turbine but not sure about the HTA Green . If you look closely at turbine pics the one FP uses looks larger and uses thinner section blades .
If I had to guess I'd say the BBK Fulls turbine is smaller possibly lighter and has the rotating assembly zipping up a bit sooner and bringing the torque rise with it .
Its always critical to match wheel speeds with turbines and compressors , it shows up in turbine response .
Also boring out turbine housings , IMO less is best because it changes the housings nozzle shape and that affects turbine efficiency .
What a pity there is no TD06 twin scroll turbine housings in Evo format .
Don't forget to keep an eye out for results with the HKS BB Evo turbo . I have a feeling they are going to be good .

I still dont know why a back to back hasnt been done on these turbos. they have been out for long enough. its as if people are being asked to hide the results or something. makes no sense to me. we even have vendors here saying they will have results in a WEEK. its been MONTHS, yet no back to back.
im still debating on what turbo to buy, and was hoping for those results.

So can we take this to read that the BBK Full comes on a little earlier and tapers off a little before the FP Green ?
Must get onto that linked site , cheers A .

I'll be posting a review of the BBK vs. HTA Green soon (same car, same conditions, etc.). Just looking at the reported flow ratings the turbos I suspect I will see 40 - 50 whp more with the HTA Green. What will be interesting is reporting on the 'transient response' as that is something a dyno cannot answer. From the people I have spoken to that run the HTA Green, response is awesome, so again I suspect I'll be happy .
More to come ....

Cij: Sorry to hear about your BBK's untimely exit. Will you be using the FP oil feedline upgrade on your new Green? Also, which compressor housing configuration will you be going with? Good luck
