Hey Guys
I have a build thread or ride thread here about my car. just got it pretty much back and run in the engine and tuned now. Just thought i would show it around and get peoples opinions, honestly i was expecting more power out of it, whether or not the dyno is reading a little low which is what i hear around down here.
But i know people on the US threads are more pro 7M so wouldnt mind getting some more perspective on it. cheers guys

Re: OZ Turbo-A Dyno
Hi mate, good to see another turbo-a! I notice your running a 7mge intake camshaft, well your mid range is strong to be expected but i believe if you run somthing a little more suitable for your mods you may yield a much stronger top end. The 7mge camshafts are great for low to mid range then just drop off once the revs pick up, it's been discussed a few times on here if you search.
Great work so far and look forward to more updates and details on your beast.

Re: OZ Turbo-A Dyno
Yikes, i just noticed 20lbs boost with a t04z ....Just as a rough comparison my turbo-a stock internally made 350rwhp with just a map ecu and 550 injectors and a 60-1 at only 14psi boost. My opinion is your figures are low for your mods but every dyno is different so don't stress.!
What was your afr's like?

Re: OZ Turbo-A Dyno
what kinda torque #? how much timming and what fuel?
have you done a compression test to this engine?
if compression checks out ok then, some different cams and cam gears should hep out a good deal.

Re: OZ Turbo-A Dyno
not a compression test yet no, its a newly built motor so havnt really thought of doing it yet.
not sure on torque, didnt get a printout of that will prob have another chat to the tuner when i get a chance.
was on premium pump fuel.
am thinking of trying a mix of premium and race fuel (recommended by Dan - HKS TRD)
and maybe a power run on different dyno to make sure its not just me being paranoid.
i do want to do head work to it, just didnt have the money at the time of the build to do it and if i was gonna put cams in it i would want to do everything while im there. All in due time, but i just know of people making big numbers with less mods then me 
cheers guys

Re: OZ Turbo-A Dyno
I have a pair out of a turbo-a if you want them for $50.00.The cam lobes are the same profile as a normal 7mgte but unsure as to whether there is any difference in duration (should be just the same as stock).
