Down On Power?

[dead32]

hey guys i reccently had my rb25 tuned, the problem is the car only made 192rwkw on 12psi, even though when i load it up it stays at 10psi, ive seen many std rb25's make this with std ecu etc and now im questioning the tune,the car had some high knock readings under light throttle uphill say 3000rpm not giving it a hard time. to the point where they had to pull timming out from below std settings. this also didnt make much sense.. mods are:

rb25det

std turbo,injectors,afm

greedy plenum

front mount

3inch exhaust

600x300 cooler

fuel pump

powerfc

boost controller is profec B 2...

i wouldve assumed an easy 200rwkw should be in order, the motor is very healthy with good compresion and lil to no leak down...am i expecting to much from these mods? whats your thoughts?

dyno sheet

thats all the stock turbo is really good for mate. i say youve done pretty well for 12 psi.

All the other people making 210rwkw on stock turbos are getting LOS results (load of shit)

So dont worry about it.

If the car feels fine, 10rwkw on a dyno sheet means jack all.

They are all different

yea thats what i was thinking, realistic dyno. only problem is it doesnt feel all that well on the street. unless i was just expecting to much,i just cant understand why they had to pull the timming out "less then std" in some load points around 3000rpm. it makes for a very "doughy" pick up if you catch my drift.

Ryan,

My RB25 was 195rwkw with same mods minus the plenum.

Maybe go to another dyno tuner for a comparison run?

Or, with my tuner, he says if Im not happy, bring it back and they'll fix it!

Give the person who tuned your car a call and have a chat and tell them your thoughts etc!

Cheers,

Chris

i wont be returning to this particular tuner for reason's i wont go into publicaly. ill just leave it as is. its not like its a dud.

ill just get some more parts together and then take it somewhere else.

Ryan, feel free to pm me if you like

I know the ceffie was quick without those mods (Ando beat me by .6 of a second!!! ) so take it to the track and open her up, see how she feels!

The only way your going to improve this figure is with an adj. exhaust cam pulley so you can get some timing into it [then you can pull it back/trim it to suit]. Then I'm only thinking around 200 -210, so you might make a slight diff, but if you have plans to go bigger turbo and cams etc I wouldn't waste my $$$ on a cam wheel.
