Powerplay@Willowbank 21may2011 Cruize in XR6 Turbo
XR6 turbo cruises around Willowbank . Came off the Dyno the day before but on the day we were down a heap of power when the vacuum hose came off the blow off valve. Would have eaten the cobra and would have been a good race with the Evo at the end. NEXT TIME!
XR6 Turbo @ Powercruise 2010
Taipan Motorsport is very proud of both our pit girls (Marta and Camilla) for there outstanding efforts over the weekend at Powercruise Syd 2010. Hope you enjoyed the ride Marta. From all the team at Taipan, thanks girls XXX
For those wondering, I did crank the Boost above our Dyno shootout effort just for Marta, wouldn't you?
Massive shout out to the Team at MR HDT, you guys are the Big Guns of the event not the cars.
Special thanks to Troy and Michael from turbo Smart, your products are the reason Marta had such a good time.
Special thanks to CV Performance, your the man Con.
To all the Team at Taipan, Michael, Damian and Scott, funs over, back to work :)
Atomic Performance Products - XR6T High Performance Valve Springs
Atomic Performance Products have available a range of heavy duty valvetrain weapons for the Ford SOHC and DOHC 6 cylinder engines. Our range includes H/Duty and Race Springs, chrome moly retainers, machined chrome moly valve locks, stainless steel valves and anti pump-up lifters.
Valve Springs
Standard valve springs suffer from varying seat pressures from new and once subjected to cyclic operation (even for a short time) can lose tension rapidly. This loss of tension can lead to "valve float", a condition whereby the valve is not returned cleanly to the valve seat, allowing it to bounce off the seat and releasing vital cylinder pressure. The resultant loss of pressure creates a misfire, followed by either erratic idling and/or stalling.
All valve springs lose tension after being installed - and because the original Ford valve springs are quite weak, even a small loss of tension can bring about this condition. turboBoost pressure also works against valve spring tension on the inlet valves - the DOHC Ford 6 cyl inlet valve has an area of 3.5 sq inches approx, so for every pound of Boost, roughly 3.5 lbs of valve spring tension is deducted from the spring pressure. For example, if the spring has 50lbs of seat pressure and the engine has 7 pounds of Boost, the net effect is that valve spring tension is reduced by 24.5 lbs to only 25.5 lbs of seat pressure, which is inadequate for almost all applications.
Atomic H/D or Race springs are definitely not repackaged Ford V8 or Typhoon/Tornado springs (which fatigue just as quickly as the originals) but are custom wound from premium quality USA made nickel chrome vanadium spring steel, heat treated, shot peened, scragged and packed in matching sets of either 12 or 24 for use in all 4.0L SOHC and DOHC 6 cyl engines. Suitable for use with either standard or Atomic camshafts, no expensive cylinder head machining is required and the standard valve spring retainers, seals and locks are retained.
Changing valve springs on the Ford DOHC engine has become quite a bit easier with the release of the Atomic on-car valve spring removal tool - part #100704. Rather than having to remove the cylinder head to gain access to the valve springs or using levers and collars to change the springs on the car, our patented tool allows all 4 springs per cylinder to be changed simultaneously - the entire job can be undertaken in only a matter of hours. No special skills are required and the possibility of dropping a valve collet into the engine is substantially reduced. Please refer to our Tools and Tricky bits section for further information.
