Running without a mbc

[tpunx99GSX]

Ok correct me if im totally wrong, but if i take out the mbc and just connect the lines that go to the mbc, will that just use the boost that is set by the tial spring (7 psi)?

[1ViciousGSX]

Yes, as long as you don't have boost pressure applied to the top of the Tial.

[tpunx99GSX]

yeah there is no screw in the top of the tial, so i should just be able to do that without any problems. The reason is i think my elite mbc is messed up. I think i was told the initial setting on the mbc. should be when the little ball stops rattleing. which should be the lowest setting, well that setting is like 15 psi, which is more then i want to run. so i think the 7psi should be fine for now.
and i havnt even heard that tial open up so im hopeing that this will in effect test whether it is working or not. lol

Why run less than 15 psi? If I remember correctly, 14 psi was stock.

[tpunx99GSX]

because i really want to hear if the wastegate is doing is job. and the bigger turbo also flows a lot more then the t28 right.

[1ViciousGSX]

If you are not "overboosting", the wastegate is doing it's job.

The bigger turbo will work more efficiently, but the airflow will probably stay the same or go up slightly, but nothing to worry about. Adding more boost will make the airflow go up, but that's what you want, isn't it?

Vicious, he has stock injectors.

[1ViciousGSX]

Stock injectors should work with 15 psi.

[tpunx99GSX]

see thats the thing the stock injectors arent working with the 15psi because its allowing too much air in, hence why i want to wait until i get the 680s on so i can turn it up with out knocking like a sonofabitch. So i figure 7 psi should be fine until i get it on the dyno and get my injectors.

Better safe than sorry.
