yes and jez had boost issues as well but that was because of his gate.

BSA had the same gate mod and he didnt have any spool issues and his was plumbed up the same way as well.

im gonna try with a bleed valve or borrow a profec b2 off Jez if he has time, so we can try it out.

mm. well its nothing to do with them that its dropping boost.. I just wanted to know.

I dont think the issue is in the turbo either, that rear wheel and housing combo has been proven plenty with the T67s and I doubt the 20g will throw it off that much that it caps out that early.

Try get the boost to stay on I guess. Did you try running a higher duty and lower gain? IE slow spool with high target?

My issue was opposite. I had boost creep due to a small 34mm gate.

Try plumbing the boost line into the top of the gate to help hold it shut. 5minute job, other wise come grab some springs and the profec b solenoid and control unit to try

Yeah, my tuner played with the gain, it doesn't make a difference.

thanks mate, getting it back tomorrow morning so will give it a try then. the MVR springs won't work with my gate :(

Have you considered the gate mod to the manifold might be holding it back? I wonder what would happen if it was plumbed off the rear housing instead with an intact manifold.

And that is some pretty rapid spool. Will be interesting to see the final result. Don't forget Jez has the same turbo and housing.

Yeah I would be looking at the manifold/gate arrangement

dont think this would be the case Simon, Blake (BSA) had the same manifold setup (but smaller gate) on his car and it wasn't an issue

what spring are you using in your gate at 1.5 bar ?

    • Some troubleshooting, connect up a timing light/gun with a proper ignition lead on coil 1. Hold the revs at 4~4500rpm and see if your timing is all over the shop, scattering off its tits. If so, there's a high chance your CAS is fked. But I read you have a Link ECU ready to go in, why not just skip all this and put that in - will make troubleshooting so much easier.  
    • Misfires when the car is fully warm are generally attributed to the coils (and/or the igniter, on cars with a separate igniter). They can stop working properly when they get hot for a number of reasons. Either electric/electronic, or from thermal expansion opening up gaps and allowing HV leakage. Seeing as you have replaced the coils, that could/should rule them out. But I wouldn't always assume so. Were the coils genuine? Or is there a chance you have bought some counterfeit Chinesium shit? Then we're back onto loom connections. They can fail when warm/hot for the same reasons. Inspections, cleaning of contact surfaces, ensuring that terminals are fully inserted, etc etc, are all justified. The same (heat effects) holds true for the other electrics and their connectors. AFM & CAS, primarily. If you try that Chinesium AFM, drive it around on low load until it is properly hot, but do'nt give it more load than you have to, except when you need to see if it will still miss. I'm dead serious about the untrustworthiness of the calibration of those copy AFMs. Injectors are unlikely to get hot unless the fuel is coming back around hot. You could try squirting them with compressed air or freeze spray to cool them back down to see if they are maybe the cause.
    • Alright, all the plugs looks good. Noticed that it starts to get bad when the car is up to temp, that's when things starts to misfire hard. next to do is Injector cleaning and such. Got in touch with a shop to do work on the injectors next Monday also help on diagnosis.

    • Hence why I've only modified my car into a pure daily. Everything has to remain reliable & roadworthy, while providing value and grin factor. It also must not be handcrafted to the extent that the car will be immovable if something breaks because you cannot get or make a replacement to at least limp around with.
