I'm not sure if your correct above the late model mk2 having typhoon springs,and did you measure how much spring clearance you had left  before coil bind using the 290 spring I hear its dangerously close.

<{POST_SNAPBACK}>

I'm going on what I've been told by to parts guys at two different Ford dealers.

I didn't measure coil bind - I was assured that it would work by Ford. They did the job for me and have warranteed the work.

I think they are very close about .015 thou most people reckon .050 to .060 thou.I guess if they miss they miss but it does'nt leave much room for error

Either way, if I have an issue with it I will take the car back to Ford for warranty. Their work including parts is covered by Ford warranty :nono:

Installed a new in-tank fuel pump capable of supporting over 550hp to alleviate fuelling issues. The difference is very noticable, which is good. However, due to the lack of any baffling in the fuel tank fuel pickup is an issue with less than half a tank of fuel showing on the gauge.

I'm having a small baffle made to fit around the in-tank pump, and now will also install a surge tank. The in-tank pump will feed the surge tank, which in turn will supply fuel to a new external fuel pump.

The stock fuel pump is definately not capable of supporting over 300 - 320rwkw, even with the relief mod, neither is the stock fuel pump cradle sufficient to keep the fuel pump supplied with fuel in high load applications.

Power is now capped at 330rwkw, although it has seen more. I don't see the necessity of running the car with 350-360rwkw in it's current trim as I'm sure the bottom end will fail.

I guess it's about time to start planning for new rods and pistons :spoton:

Awesome project you got going there Jas...

Any chance of seeing you run some times at the plex?

<{POST_SNAPBACK}>

Thanks Steve.

Before I head to the drags again I need to replace the clutch centre, which should hopefully be done by the end of this week.

Might get there in the next few weeks.

Nice results Jason. I like your max psi too..

When the actuator was modified, was the port enlarged with a bigger flapper fitted, or just a heavier spring used??

How much did changing the rear exhaust section pick up? was there boost spiking as a result?

What injectors are you using?

Cheers.

Jeez, now you're asking me to divulge all my secrets..... :laughing:

Stock swing valve and port size.....

Rear section removed the restriction of the stock exhaust setup...minimum power gain 25rwkw.

Boost spike was not caused by the installation of the new rear section, rather the temporary catalytic converter 'fix' due to the bloody thing failing, but that's another story and am following that up with SMB. In the mean time a 3.5" metallic substrate unit has been installed and boost does not spike. Infact, boost is more controllable now with the new exhaust and actuator assembly than it ever has been :laughing:

Bigger than stock injectors are used, but not Bosch 968's, yet. Am working on sourcing a heap of them at a realistic price through a contact I have.

Might have to get the car to that 'other' dyno and see how much power it makes there :laughing:
