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 ?

    • Yeahhhh, the costs have killed me. Spent more than the cost of an engine rebuild and it most mostly servicing and a tune lol.
    • I'm not 100% how the BMW racers do it, but I know from other brands like Merc, moving, and changing the coolers is one of the things. Like getting a transcooler out from infront of the radiator to out near a wheel arch. So some of the stuff you've got crammed in the middle front, spread it out and open up where you can in the bar to get more air in to the sides.
    • Small update for the day... Turns out the intercooler and engine coolant hose kits are anything but complete....I probably should have counted better but it only really covers about half the coolant hoses in the car, it really just covers the visible stuff and pretends everything else doesn't exist (turbo water feed and returns and also heat exchanger lines through the 2 pumps and cooler) .In any case, I'm happier to have half reliable hoses than none, but a bit of a disappointment. Anyway...finger click (and 5 hours).....hoses in place, lots of spring clamps replaced with screw clamps, and engine coolant is on the pressure tester for the night.   Incidentally, upsized header tank is an Inifiniti factory option....not sure I'll ever do prod car racing in this but at least it is legal.
    • Just weld it onto the hot pipe. If you want it right after the turbo, put it right after the turbo. Or rip the comp cover off and drill and tap a hole into it.
    • hahaha glad I can rely on you two to go on a spiral at the drop of a problem! Some quick answers....the ducting is excellent top bottom and sides....everything that gets in goes through the coolers (noting the oil cooler redirects it out again, fair call if it is cooling 120o+) and the heat exchanger for the intercooler also has some scoops to pick up more than it's fair share too. I can't see going down the water spray track....no bueno for formal racing and a big risk for long rally days if you run out (plus I'm not clear if it is allowed there either yet).   Frankly, it must be possible to reliably put 400kw through a standard front end, the BMWs do it so I just need to work it out....I'm starting with reducing blockages in the way and adding some coolant capacity with a bigger header tank, flushing rad and making sure it was filled/bled properly (I didn't do the last coolant change); also taken measurements incase next step is a bigger/higher capacity custom radiator
