FP Green vs Dom 2
I have messed with both before 
probably one of the very few owners to have done it .. this is done on MR .. so daily driving is subjective because the gearbox likes te bigger turbos
Lag WAS my biggest worry .. surprisingly .. both had very little in terms of daily driving .. I am back to the older 7/8/9 evos with the TD05H !!
Both turbos spool about the same time and both hits full boost around the same rpms .. 3100~3300rpms @27-28psi in 4th gear (3rd was around 35-3800rps) .. and 5th and 6th was around 3000rpms
midrange for both are about the same obviously ..
The green can hold slightly higher boost between 28-30psi and tapering to 25psi at 7500rpms ..
The Dom holds around 28psi and drops to around 26psi at 7000rpms
airflow wise .. Green flows around 410-420g/s at 25psi 7000rpms versus Dom2 26psi 370-380g/s
Just a yardstick for comparison .. stock turbo flows 320-330g/s at 21-22psi 7000rpms
Drivability wise .. the Dom2 is a better street car .. though this is very subjective because the ingear response at part throttle is slightly better..
Overall quite similiar for these 2 turbos ..
I'll be trying out BB-X later .. maybe .. if HB speed is nice
Or another prototype ..

Thanks Gunzo!
Why does the MR "like" the bigger turbos?
Would love to hear your comparisons on the BB-X as well, if you could try to remember to update this thread 
It likes the bigger turbos because of lag...more lag = less torque on a turbo car (almost always). the sooner we make boost the more potential torque we have.
The MR hates torque...so it likes bigger turbos.

Ahh thanks! Hopefully we will soon know the upper torque threshold of the MR trans with greater accuracy/certainty.
Ah .. thats not what I meant .. the car made 350-380ftlbs torque midrange .. enough to kill stock manual clutches too
the shifting logic of the SST kept the engine running at the sweet spot when you need it .. like when you're in 6th at low rpms 50mph or so and you need to overtake ? On the SST, just jab the throttle and the engine blips to 4th .. bam 4000+rpms and you're away ..
wonder why FP claims 54lb flow capable .. flow is closer to to 48-49lbs .. and dom is closer to 47lb .. maybe E85 hehe ..
For some strange reasons .. I only get occasional updates on some threads .. and sometimes I don't get updates at all ..
