Works for me. That looks like my RB25 dyno when it was stock. My A/F's were a bit richer but I had that same dip in power....But if it's your dyno you have an RB20 so hmmm.

yep

is that dip normal ?

the motor is no where close to a stock rb20

mod list goes like that : 550cc gt-r injectors 20G turbo hks cams ( no clue which ones they came on the motor ) some kind of cam gears ( came on the motor as well ) stock side mount leaking pressure and could not hold more than 7-8 psi

it did 186hp the first couple of runs then we advanced the timing .5 degree and it came out to that run u see

It shouldn't have a dip like that. You might need to tune the cam gears because the power is falling off worse than a stock cams.

i hate to say it but for the mods thats a sad dyno run.my hella stock rb20 put down 227 on a dynojet with an excelent power curve and a nice torque plateau.i would remedy the leaking intercooler and get some sort of ems (pfc or aem) and sort the fuel and ignition tables.with the mods you have the engine should make obcene power in the high end, due to cams and a large turbo.

well i know it shouldnt be doing that little powa and thats why i asked for opinions on wut the dyno look like to every one around

i will be advancing the timing on the next dyno tune and i either will blow it or gain all the power it should be making

got the intake mani on and the front mount on its back to life after it was sitting for over 6 month
