that would be nice, but wont that lag like a bitch?

 

Who cares? From 4900rpm-6800rpm it will be worth it! Thats enough to make anyone forget about the lag

 

but wouldnt you get pissed off having to wait until 4000 rpm for power driving around town?

 

But still more power down low , just gotta wait longer for the maxx. Correct?

 

just be in the right gear. six different gears shouldn't be hard to find one!

 

They were doing some pulls today with it when i was there. dont know what it made but the turbo was loud as hell

 

the sr55 will spool 18psi in about 3800rpm....


its true "sweetspot" is 20-21 psi;

that is where it becomes truely lethal.


the issues of the stock solenoid being capable of holding boost and acheiving decent spool is a pertinent one.

there are solutions for that, too...

with th sr55 on the ej257, (and the correct intercoolie, intake, ebc solenoid, and exhaust) you will still have VERY good spool, and the ability to advance ignition timing down low to offset any perceived lag.... (keeping in mind that this motor is a time sensitive beast).

my guess...... 380hp/370tq SAE corrected

i expect it, actually............ (with the 3" stro exhaust even)
