Spun the 4dr EF on the dyno, results inside.
Had a chance to take my turbo LS-vtec 4dr out to the dyno on saturday and got some baseline numbers.
Motor is a LS-vtec with 90 B18a bottom end with mahle 9.1:1 forged pistons, scat rods, etc... head is a 99 B16a2 head, left it stock for now, i have a ferrea valvetrain and crane cams new turbo vtec cams lined up, just need some cash
management consisits of a PM6 running turbo edit and AEM FPR set to 37psi.
dyno run was done on a dyno dynamics with no correction factor, unlike the dynojets out there.
first pull: 120.7whp with major lean out in the top end, vtec activation at 4900 rpm.
second pull: 140.9whp, upped the fuel pressure to 52psi, moved vtec up the 5200rpm
third pull: 135.6whp, upped fuel pressure to 60psi, left vtec at 5200rpm, definate loss in power.
boost was at 3psi, with 440dsm injectors.
the tuning was primarily just a basemap i created with xenocron's basemapper program. We went back and played with the values for about an hour, but i didnt have time to get it back on the dyno. I will be going back this weekend now that i have 1000km on the motor, i will put the 10psi spring back in and give her ----.
Overall goal is 15psi, but my 440's max out at 11psi, so itll be on to 600cc injectors and a new fuel pump before it gets the 1bar spring.
ill post up the dyno sheet when i grab my willem burner and spares chips from the dyno shop.

Just out of curiousity how much do you have in just the LS/VTEC setup less the turbo stuff?

dude, those numbers are hideous! 440's max out just a hair over 300whp, so you have a lot of work to do before you even think about maxing those injectors out. i'd be worried about a lot more things other than getting new injectors :P what kind of goal is '15 psi' you just want to be able to say "hey, i'm running 15 psi!" or would your rather say "hey, i put down 400whp" ?. what turbo was this with?

Re: Spun the 4dr EF on the dyno, results inside.
believe me, im not too happyy with the results. Im diagnosing the problems as i can find them.
projecteg: its about making power and being able to say i pushing 15psi. 15psi is useless if im not putting the power to the ground the way i want it.
turbo im using is a T3 48 trim turbine, 60trim compressor
im into the complete setup foir about 1500us, if that. It helps to work at a speed shop.
Ill keep everyone updated.
I found an exhaust leak at the manifold flange, gonna fix that and see how see runs.
