It's a 12psi outer spring, so that gives me a 7psi inner, 10psi middle and 12psi outer, for a total of 29psi. Will I try and run double the spring pressure for 58psi worth of boosty goodness? Probably not. Will I eventually run it at 100% wgdc just cos? Probably yes. What does that mean? All of the boost, all of the time and at least 23 in the mid. I'm getting it couriered to work so should have the farken farker sooner rather than later. 2 2 Link to comment Share on other sites More sharing options...

Maby it’s a better option , please send yours to 40 psi for me 😂 😂😂 my wish list is NOS , 218c and cnc ported head , I just worry about the bullet pistons 😂 Link to comment Share on other sites More sharing options...

The intake cam ended up advancing about 5 degrees and the exhaust ended up about 7 advanced from what they were. I left them both 2 degrees advanced from the cam card cos the lifter bleeds down as you open the valve 1mm, so it'll be pretty close to the specs. Boring info here, it takes about 35 degrees of crank rotation to go from the valve starting to open, to the valve being open 1mm. The car is a lot quieter now which is good and seems to come on boost quicker and smoother. Oh and it turns out the wideband sensor wasn't stuffed, the wideband is still having a fit so fark knows what it wants. Mebbe a recalibration is in order? Anyhow there is that and I suppose next weekend I'll have some more WG spring in it and see what it can make then.

I'm pretty sure the venom cat is the restriction so I'll make up a decat pipe for testing purposes. 1 Link to comment Share on other sites More sharing options...

Went for a quick drive and whether it's the changed cam timing or different sensor, it seems to have leaned out a touch. Will have to get it back on the dyno and get the fuel sorted again.

Tom Tucker Donating Members 669 Member For: 5y 5m 25d Posted 24/05/21 09:36 PM Share Posted 24/05/21 09:36 PM Is the wideband able to feed a trim adjustment? that's what I love about the Haltech, long term learning function. Link to comment Share on other sites More sharing options...
