I just got off the on 3 thread and im pretty sure I'm leaking boost from the compressor housing bolt hole. Once your *** gets back from vagas we will go for a ride, as long as i get to ride in your 7

I fixed the hole today and its still doing the same exact thing. It will only get up to like 6lbs of boost at around 5500rpm in second gear since i don't have much of a first gear. If my waste gate was in a bad spot i would have creep issues. I think its in a good spot. It starts to spool around 3000rpm but takes so good damn long to actually build up pressure. I looked at my cold side yesterday and it all looked good. This is starting to drive me nuts. I am going to look at every little possible spot and even probably pressure test it.

get a pcv cap from home depot, thread in a air hose fitting and hook up an air line regulated to 20psi from the air compressor. You will find any leaks.

thats my plan for tomorrow. will the intake hold pressure or do i have to block that off?

and dave, heres how my gate is set up

Sarg

I would block off both sides with a pcv plug/cap. Just get one that fits snuggly into your silicone coupler.

Also, what spring do you have in your wastegate?

T76s10

iTrader: (6)

Its supposed to be a 9lb spring. I ordered a 13lb yesterday so we will see how it works

Sarg

Do you have an atmospheric dump?

T76s10

iTrader: (6)

It dumps into the exhaust stream. Look at the pic in my sig

Sarg

iTrader: (6)

Oh sorry, was on mobile and it does not show sig pictures. Was going to say if it was atmospheric you could here when it starts to open and tell if it is opening early. Much harder to tell when it is recirculated.

T76s10

iTrader: (6)

Yeah to bad i didn't levee it atmospheric cause now i can't hear any difference

I think i need to leak test the hotside piping. With the mbc cranked for full boost their is no way that wastegate is opening up at 5psi even after i modified the spring. The blow off valve is releasing tons of air so its hard to believe that i have a leak in the coldside. It even did the same with my old cold pipe so I'm thinking it has to do with the hotside. Even though the turbo is screaming at 6000rpm its hard to believe that compressor is only pushing out 5psi even with a exhaust leak.

Great spot for your camera, at least everybody will be able to see me pass you like your standing still! Lol Jk. We still have to line up. No chickening out or coPs.

Lol at this point you will i can only make 5lbs right now. I had a bad feeling about doing another pass with you that night too but of course you had to get me pulled over lol. We didn't get tickets though so its all good. We will have to race atleast once though before snow fall

It sucks that your truck isn't running right. You going to Automotion in the Dells in May?

rm1985z28

I can give you a head start if ya want? have you tried to bypass the intercooler? To see if that's restrictive? Or remove the vac line from waistegate

We should start a thread about automotion closer to may. I go every year. It would be cool to meet you guys. Met black 98s10, at C&S last week.
