That's actually less fuel than using 1200cc secondaries....probably about 360-390 rwhp, depending on duty cycle and fuel pressure.

i know its less fuel but i was going to run this setup for a while before i find a set of 1200s or 1300s or have another set of 850s sent off to be bored out. and when i get the 1200s or 1300s ill be putting the 850s in the primary spot anyway...

why would you want to run your injectors past the safty zone of 80-85%...at 85% with 4 850's would be something like 420ish flywheel....

just wait until you can get the 1300's if your planning on making more than 420 at the motor or roughly 360 rwhp
