Is it bad to run on wastegate pressures?

[Blu90GST]

I skipped my bcs when I did my vaccuum lines. I'm running all stock fuel system for a 5 speed with a 14b. I'm getting around 13-14 lbs of boost on the stock gauge (putting in a real gauge soon)

a lot of people delete the bcs especially when doing a mbc you're fine and as you obviously know stock boost gauge not accurate.

Yeah I was just wondering because I'm running stright from the j pipe to the wastegate

You're fine thats how my gsx is set up with a mbc in the middle

And another question that's not really related but it has me worried, I recently replaced my head and now my heater core hose coming from the back of the thermostat house was steaming. I plane on putting a new hose clamp on tomorrow but I was wondering if I should be worried about my headgasket not sealing and pushing compression into my coolant system. What are the odds of this?

 

[lasershark]

definitely replace the hose or clamp and don't let it over heat, aluminum heads don't like that,keep her full of fluid but a bad hose alone won't cause catastrophic head gasket failure

I mean my headgasket not sealing correctly in the first place and pushing air into the cooling system

Did you properly burp the cooling system? Do a compresion test and see what your numbers look like. You could also do a cooling system leak test and see if it holds proper pressure, if you have a tester. I would try to do both of those test and see what you come up with before anything else.

How do you burp it?

and conpression check tomorrow

Take thermostat cap off, turn car on, let car run for 5/10 mins while every now and then turning heat off and on. Squeeze top and bottom radiator hoses to push air out of them. You will notice bubbling from the cap. Once the bubbles stop, or slow down quite a bit, you are good to go.

ok thank you. I'm hoping I can solve this without it being anything major

The BCS or an MBC can only raise boost not lower it so running at wastegate pressure is the lowest it will go, so it is safe.

That is completely different than running it at wastegate pressure.

 

[Blu90GST]

I'm running without the bcs. So whatever that's called

the concept of skipping the bcs is the same though and thats what I was referring to, obviously it's not the same as running at wastegate pressure or nobody would own a MBC

sounds good

free post count?
Just so i'm not doing the same thing, only way this is bad is if you dont block off the other nipple that it was going to.

The one on the air can?
