Well i got my car dynoed yesterday in brisbane!

turbo-a supra, 7mgte
all the usual mods, map-ecu, pressure reg, pump, spearco cooler, etc etc, 60-1 garrett ct-26.

it made 360hp at 14psi with 493nm!
will scan in the dyno sheet, but gets a small knock in it at about 10psi, and gets really bad above 14psi!

engine was detonating eariler! cant seem to find any more info on "turbo-a" ecu's.. dont think it likes to be messed with. it spewed out a couple of error codes, but fixed them.. so rather spend money on a ignition controller im better of going full stand alone i think!!

Then my car wont be original much then :(

I'm NOT calling BS Dan it's just intersting to see the difference the smaller Hotside makes.

It took me 17psi to make 264 a couple of days ago so something is different here.

All good I knew you werent, anyone who knows me knows one of my pet hate is BS exaggerated dyno figures.

Wow thats interesting on the power figures, perhaps you being auto makes a big difference? Though my Brothers car with a stock 35R makes 290 odd rwkw at 1.2bar and he runs an MV built auto with high stall and no lock up clutch.

My comp cover would be smaller than yours even though we have the same wheel right?

By seat of the pants it feels right as while it doesnt have the electrifying midrange at 10psi like the CT-26 had at 20 it definately goes harder from 4000rpm up and doesnt drop off at high rpm like the CT-26 does

Dan: Pretty sure the Comp covers are the same.

I still have some fiddling left to do as I was getting spark blowout on the 17 psi run around torque peak :(

Mine was done on 95 PULP (93 octane)

It really started pumping hard above 18 psi but due to the spark blowout we couldn't run it like that and the usual fix for this condition is to add some timing but that of course rattled the engine so we dropped it back to a safe tune.

Bugger. I'll find out on the comp covers but I was always under the impression that the Z one was larger, which is why I canned any thoughts of going to one and hi-flowed my turbo instead. I only have 5mm clearance between my intercooler top pipe and the comp cover as is and no room to move unless I do custom manifold.

I was using premium unleaded, and octane booster, though, just like on the street, in summer I can run full boost with no booster but in winter it rattles anything above 1 bar, I have been told fuel is seasonal? Its been like this on the standard ecu too. When the Motec first got installed we could run 1.2 bar with straight pump fuel, its all in the luck of the draw when you fill up I find.

For ignition all I have is the original coils, new TRD leads and a bosch 3 channel igniter and thats it. Works a treat so far
I'm confused now, I thought you ran LPG?

The LPG while it made great power (410 rwkw on the 3540r) was problematic so I went back to petrol as it's "easier" .

Winter will have denser air so you may have to crank the air temp compensations a little to allow for this?

Yep Octane can vary a LOT from tank to tank.

No probs at all I'd like to catch up for a chat!

If you know the duty cycle and injector size I can calculate the HP you made
(mine comes out damn close when you factor in the auto trans)
