You should call the new one....

In case it didn't reach down unda here's the reference:

I say go for what you are tuned for now. If you change you'll likely need to spend some time dialing it in. I have found it's not just scale the injectors and go but there is a bit to be gained playing with leaner AFR and timing...

Swapped the pressure guage over to front scroll today .................
Original exhaust @12.5psi
.................Front scroll ..........rear scroll..........
3000..................5........................4.. ...........
4000.................11.......................9... ............
5000.................14......................13... ...........
6000.................18......................17... ..........
7000.................24......................22... ..........
8000.................30......................27... ................
New exhaust @16psi
3000.................4.........................4
4000.................11.......................9
5000.................16......................15
6000.................19......................18.5
7000.................24......................23.5
8000.................29......................27.5
Looks like the difference between scrolls is less at higher flows as i had hoped.

Must say I'm surprised by how high back pressure are. I dont know why, but I had guessed it would have been lower. Kind of makes sense with quite a lot pressure when 40-60Hp is required to drive the compressor.

Corky Bell has this to say about it :
It is this writer's opinion that a good street turbo system will show the ratio of TIP to IMP t.o be approximntely 2. If a ratio of greater than 2 exists, the turbo is too small and is choking the system down and not permitting much power gain. If the ratio is less than 2, often the boost theshold will be higher than desireable for commuter Car use. This situation is offset by t.he fact that as the ratio comes down power goes up.

IMP= Intake manifold pressure
TIP is not just telling if turbo is right size but also if your entire system is ok .This is why I've been comparing mine against the matchbot numbers . Even though mine is not a BW turbine , I've been able to match it up with one on their chaarts and see where the other weaknesses are on my setup. Would be great if you could look at yours for comparison
