Turbo BS Thread

No but I've been talking to mc1337sauce he was having the same problem and so I'm gonna try some things and I'll get back

 

what things...?

 

Nice. I've started looking around at rear shock relocation brackets. I'm in the process of piecing together a lift for my truck and deciding what exactly I want to do with my rear suspension. Being a prerunner, I want to maximize flex/travel in the rear for keeping the drive wheels on the ground without going too crazy. Definitely don't want shocks poking into the bed, but I'm thinking a SUA swap would be nice for controlling wheel hop/axle wrap when I get around to adding more power.

 

You get rid of all the vacuum leaks? Could be a bad maf.

You can also try to run it without the BOV. Just unhook the vacuum hose and cap off the nipples and the BOV will stay closed. See if that fixes it.

 

This and that.

 

I'm going to check everything tomorrow

 

He said that he ended up using a lighter spring and that got rid of the stalling

 

@FlapJack935 when you get ready pick all our brains good. Depending on your budget we can make some good recommendations for you.

 

That doesn't make any sense...

 

That's what I thought too but here we go

 

Do yourself a favor and eliminate the BOV as a factor. Remove the vacuum tube from the BOV to your manifold and just cap those fittings off then try a full power run. If it still stalls, you can rest assured its not the BOV/spring. If it doesn't stall, I would say the spring is too light.

Try not to jump to conclusions and get married to one. Weigh all the possibilities and start with the easiest and cheapest troubleshooting.

 

I think he did this a few days ago and it still stalled

 

Yes I did

 

Ahh, must have missed that.

J did you ever fix that vacuum leak? You mentioned that the booger welds helped but didn't fix the vacuum. You also mentioned that cleaning the MAF helped for a while but the issues came back.

Sometimes if the trubo doesn't drain %100, oil will seep into the compressor housing (especially if its a cheap turbo) and you end up blowing oil through your intake and all over your MAF. I had to adjust mine to get it to drain better as it did just that.

Take your intake off and check inside your intake for oily residue.

Buying a new MAF can be $$$ but might be the next step but I would verify %100 you've fixed all your vacuum leaks before throwing down a $100.

 

Sooooo, those with a 2.7l. What size is the mad, treadstone has 2 maf pipes, denso and denso -2/bosch...?

Denso is 1.02

Denso -2 /bosch is 1.23

 

Check the MAF in your truck. Should have a PN on it.

Also check for oil in your intake to make sure its not just getting gumbed up.

 

Hmm I have a spare MAF...

 

Nevermind the oil theory; just remembered the MAF was on the other side of the turbo.

How's the vacuum leak testing going? Btw, if you can do a write up on that leak tester I would love to make one of my own.

 

I second this.
