Clint (profile autosports)... Yeah pushing the boundaries for sure but yes I will be buyin a n/a motor this week to start the build

Hi,

Name: theone

Car: BA 2003 XR6 Turbo

Trans: 4 speed auto with trans cooler

Power: 308.1rwkw

Boost: 10psi

Induction: K&N Filter, Hybrid 600x300 intercooler, Process West crossover

Turbo: Stock

Valve Springs: Performance springs

Exhaust: Standard, centre muffler removed

Fuel system: Fake 968 injectors (replacing with ID 1000s soon due to slightly rough idle), Aeromotive fuel pump

Power adder: XCal 3, custom tune

Comment: Very happy with the car as it is right now, very hard to hold it on the road straight, it had a lot more left in it but for the safety of the gearbox kept the boost at 10psi. I'm very happy with this power at 10psi. Only thing left to do is replace the injectors and if need be in the future put a built BTR gearbox in. Obviously going to have to replace the rear tyres fairly regularly lol...taking it to Eastern Creek when I get some time, hoping for a high 11.

Cheers

Have you ever run your car down the 1/4?

That's a lot of power for 10psi and a standard exhaust.

Hi rbjet,

My tuner was even surprised with that power gain with the standard exhaust (the kitty cat's been dropped off the bridge if you know what I mean, but still standard exhaust with centre muffler removed)...haven't run this car down the quarter yet but hoping to get it there in the next fortnight, need to get some new rear tyres first...hoping for 11s because I've seen cars with similar power figures to mine running high 11s. And yeah I know the boost setting is very low on my car, I was very impressed with the power it made on such low boost.

Hmmm dead cat might help I guess. If your power is right and you can peddle it then you should crack a high 11.

Going to take more power than that from a std 4spd to run an 11 me thinks.

Maybe but will just have to see, be very happy with 12,s to, I'll put up a dyno sheet soon.

My 4spd isn't standard but my stall converter is and I ran 118mph. I'm guessing I could crack an 11.9 with that.

so now that everyone knows my mods would I be crazy to upgrade the valve springs, get a plenum and try for 360?? im just hungry for a bit more power but I dont want to be in extreme territory for popping motors... thoughts??

Go for it

I was talking to a ford mechanic couple of months back and he claimed that the ba II had the better valve springs in them, he said he was 100% sure. But everyone on here thinks its only falcons made after 06/06 so who knows, mayb he had a bit of brain fade and was thinkin of the bf II
