Boost stops at 1.4bar - N75?

[hunker7]

Just a thought, have you checked that the cam timing is correct?

I haven't no. But car is running like a dream now, even with about 0.2bar missing. I will tighten the waste gate you suggested yesterday.

Get out on the M25 do a few roll on from 50 to 100 in 6th see what that feels like

I'll see if I can do it today, then let you know how it goes.

3rd/4th gear from about 1500 rpm & floor it. Sounds like you're getting there though

I can finallt see a light at the end of the tunnel.

Adjusted the throttle, but still tops out at 0.8 bar. Will try to make up a boost tester and do a boost test again.

But in general car feels so much better. Fuel consumption is better, and car shifts like hell.

What gear is it best to test max boost? I've been doing it 4th @WOT.

Hope you won't kill me for my stupidity. I have to floor the throttle in the floor very very hard for it to boost to 0.8 bar. On throttle body side the cable looks ok, but I will try to adjust it.

After having loads if fun this aft with mine boosting nice thanks to VRS another jubilee clip snapped tonight on the throttle body😣 fun and games

Also (forgot to mention ) I did notice your WG screw was sitting level with the top of the WG. you could try screwing it down a few turns.

Important to check though. Run the car and check the max boost in say 3rd gear. Disconnect the WGFV (N75) and run it again, post the results. You should have approx 0.4 Bar with the N75 disconnected and approx 1.1 Bar with it connected.

What boost are you seeing now then?

4th gear got to 1.8 bar before i had to brake for traffic. I finish work at half 10 so will drive home and go on 50mph road to see what i can get.

A quick boost leak test bung can be made from an empty baked bean tin and a tubeless tyre valve, then you just to be creative and find some objects the correct diameter for the other holes you need to block.

Or something like this (as suggested in my boost leak testing posts):

Because now it's boosting properly, there might be more leaks popping up.

Yep.

Yes, he came here and we did it together. But he wants to do it again to check after having done the injector seals. You fix one leak it always shows another one up
