i need more POWERRRRRRRRRRRRRR!!, Lagos was right...it becomes addictive. Options

[easternpiro1]

i just wanted to say that the consensus on boost being addictive is right... i thought i could fight it, but i just need "a little bit more"

most of you have seen the dyno sheet, and i was wondering what should i do from here? I will be getting a 3" custom downpipe and exhaust hopefully before the 17th (going to the track) but what should be next?

maybe some engine management?

mod to the turbo and IC? (or new ones?)

my goal is to get at least 40 or 60 more whp and I KNOW i will be satisfied then.

im open too suggestions! what have you guys done? or would do?

yeah it has 550s but doesnt it need them just because of the air flow capacity of the ct20b, aggressive cam and tuning?
if Toyota could of gotten away with a smaller injector they probably would have used it, right? thats what i thought at least.
I thought the 550s were used the same percentage as the 440s on a gen2,
that you could only add so much power before upping injector size, safc to add fuel or upping fuel pressure.
Im not to familiar with the gen4 characteristics though.
if you only want 40 or so thats only about 5 more pounds of boost if the turbo isnt already above its efficiency range.
what did you put down for numbers again eastern?

i put down according to the dynojet 266whp, looking for about 300-315whp

Its 540cc iirc, and they will support your power goal, and then some. Intercooler, exhaust, intake, boost controller @ 17-18 psi, MAP clamp, and you should be reaching your goal. One thing to keep in mind - your system is map based therefore it will run leaner and leaner the more VE mods you do (exhaust, intercooler etc. ) and if you want peace of mind - then dyno it after each upgrade and see how you stand in terms of A/F ratio. Then you look at the chart - if you see dips due to running too lean due to retarded timing due to knock then surely install water/meth injection dyno it again. While you strapped down and you see that your running safe with h2o injection you might want to try an extra psi or two and see if you get a worthwile gain.
I say you are easly capable of ~300whp with that setup.
