Those seem to be about 0.41mm and 0.46mm. Which sounds pretty much correct. I have been using 0.40/0.45mm for 80mm pistons.
Cool. Thanks @Arttu.

Thanks @Gixer1460. Read it again slowly
Can you confirm I have my calculation right please. 3.2" bore x 0.0050" = 0.0016" top ring. 3.2" bore x 0.0055" = 0.0018" second ring. Maths not my strong point. No maximum gap mentioned.

Fitting an MTC kit for a turbo on a Blandit. Can't seem to find a definite answer for ring gaps. Can anyone help who has experience with them maybe.

Finally got a dry sunny day. Took the Blandit for my first spin. He he he
Shoulda done it years ago when I was still a headbanger. Farkin awesome.

Decided to fit a boost guage with a recall feature. Will give it a good spank on the dual carriageway and see what it's making. If it's close to 10psi I think that's about right. Not a race bike, just something I've always wanted to build.
Gotta build my kid brother one now coz its more powerful than his H2.

the pressure at the gate is not necessary actual boost pressure ...
hence you need a reference PSI signal from the plenum ..
and be very wary off a EG a 6 psi spring being a 6 psi spring ...its best to actual check the spring does lift at the stated PSI..
your gate may well be opening under boost "but the PSI" thats making it open may well be a lot higher than the spring,s rating....
Gets coat and goes back to the wake i,m at
Aha. Now I get it. Doh! Thanks for clearing that up @Duckndive
Enjoy the wake.

I have a "Turbosmart style" external wastegate, and it has 2 ports above diaphragm and 2 below diaphragm and also have 2 plugs and 2 nipples.
What those are, are different positions to actuate the diaphragm, ie. if one port has an obstruction in front the port and you cannot put a hose to it, so you can plug it and instead use the other port.
The one below is where you should put the boost reference and the above nipple is vented to atmosphere to allow the diaphragm to move.
If you have ie. an electronic 3-port boost controller (and efi), the you would put a hose also to the nipple above the diaphragm as is instructed on the 3-port valve diagram.
Can't understand why I don't have a boost reference. I assumed the spring controlled the boost as you can get different rated springs.

A Boost reference signal does .... normally from the plenum via a 6mm pipe to underside of the diaphragm
I don't have any boost reference pipes connected. I did have with old internal gate flap set up. I need to look into this further. It definitely lifts off at max boost. Thanks chaps.

So boost doesn't lift the diaphragm against the spring in the waste gate?
See reply to @Duckndiveabove.

Have you got any of the ports connected to anything?
No bud. As it came fitted. Just wanted to be sure it was right.

How’s the clutch enjoying those dyno figures?
No problems, up to now at least. I'm sure it'll rear it's ugly head.

I have a Turbosmart wastegate on the Blandit. It came with some plugs in a bag but no instructions. Can anyone confirm which are the water cooling ports I can blank off?
Also should I run a vent pipe from it or leave as it is?

Dialled in and ready to rock.

Went for an upgrade. Looks like a proper turbo now.

I can bring the Blandit turdo or the CB1157 or both.

That's pretty good, what's the power curve like ? what was the fuel starvation symptom ?
That was a quick run up for my benefit. I'll get a better idea when I collect it. Turns out it was "mega rich".

Also finding room for an unrestrictive fuel filter is a challenge.
Lock up fitted.
