Disappointing dyno
I just dynoed my car and my numbers are a little low for my turbo. My whp was 152 and tourque 155 at 4500rpm. Shouldn't i be in the 180whp range with this size of turbo? I think it's that spring i used to hold the wastegate flapper down becasue it spikes to 10psi and then levels out at 6 psi. I think if i fix the wastegate and upgrade intercooler and charge pipes, it'll do the trick... what do you guys think.
Setup:
-D16z6
-T3(.60/.63)
-fmic (about the size of a dsm smic)
-2 1/4 inch charge pipes
-leaking log mani
-460 cc injectors
-base map (not really tuned... gets me 30 miles a gallon daily driving and boosting)

Re: Disappointing dyno
Even on 6 psi with a turbo that big you should be making more power. If you were at the dyno why are you still running a basemap? Tune that ----, son
You also said your log mani leaks, that is not helping you one bit. Fix that ---- too, son

I'd have it tuned alrdy but tuner won't be able to tune till next week or so. I dynoed it b/c it was free dyno day so couldn't resist a free dyno even on a base map. But that leak shouldn't affect whp as much. My first dyno that day, my gasket (part where turbo mounts onto the mani) blew so it was hella loud. I dynoed it without knowing that it blew until after the dyno and i hit 148.2 whp but lost hella tourque (140 tourque). I really think it's the charge pipes and intercooler. Should i go 3 inch or 2 1/2 inches on the charge pipes w/ starion intercooler?

Re: Disappointing dyno
I guess it is that exhuast leak robbing my power. Maybe even leaks from the charge pipes that i'm unaware of but all that's going out. I'm upgrading charge pipes and getting hf mani. Hopefully after these upgrades and a proper tune I'll get the hp this turbo is suppose to make.
