I havent seen it on the EF3 yet , the best ive seen on my Stock block on pump was 470 something , Im sure if i would tried i coulda gotton closer at higher boost.
The EF4 would probably hit that easily.

Interesting. If I can make 425whp on pump/91 I would be pleased. Pump/91 would be my emergency fuel of choice as I have E85 all over southern Arizona and 500whp will be easy to achieve.

The less aggressive track day tune was around 430 440 and was able to run on 91\92 with no knock

Sounds like you picked exactly what you wanted !

Will this turbos ever get flow tested? According to the original turbo release thread it was supposed to be done a few months ago

Sweet turbos

I'll be honest its not on the top of our priority list at this time, we plan to let the dyno results speak for themselves until we find some free time to pursue it.

But its hard to know what is the actual flow of turbo using dyno sheets since every setup, dyno, conditions etc etc is different. Would you say that the EF2 is about a 52lb/min turbo?

I think most people just care what a turbo is capable of in the end. Flow numbers are nice, but for instance the FPblack is rated at 68lb/min but people go over that number all the time.

Once we get more results everyone will know what the turbo is capable of on different setups.

I think 51-52lbs/min would be an accurate estimate.

That would make it right inline with the BBX Lite. Which I believe is right what you where aiming for correct?

We were aiming for 400 on pump and 450 on E85 with some room to spare and I think we've accomplished just that

Is the BBX lite a comp wheel only upgrade or both wheels?

It's both wheels and I have logged 52-53lb/min at 26-27psi

I'm not starting a fight here. I was mearly asking the question. The curves make it look like the same market as the BBX Lite. More options are always good.

Don't get me wrong sir I didn't feel you were trying to start anything, I'm just not as informed on the CBRD offerings as I should be so I had to ask

How about EF3? What is the "guessed" flow on that? I would like to use that to compare to HTA Green and BBK-Full.......I'm currently torn in between these beasts

My best guess would be 60-61lbs/min on the EF3 and 71-72lbs/min on the EF4. The EF3 has a bit larger comp wheel than the HTA green and I'm afraid I once again don't have enough info on the CBRD turbo to compare
