boost presure

[Task125]

what is the stock boost pres. for HO. I am at 22 wot.

 

[MMeier]

Task, when mine was stock, it would hit 24- 24. 5 then back off to 23 and stay there, that was with a pretty dirty stock filter. Now that it is not stock any more,:-laf :-laf, I wonder if I should've got the 60# gauge!!

 

[kaptn]

Go with the 100# boost gauge You might need it. I do

22-24 PSI Boost pressure is about all you will get on the stock 03' CTD. However if you install an EZ with the boost elbow, it will build considerably more boost pressure... ... ... ... ... . like 32-34 PSI.

Thanks guys,

I was getting 22, 23 ,today I will hook up pyro,not looking forward to drilling exhaust manifold.

 

[Kurt Henzler]

speaking of drilling the exhaust manifold. what is the best way of doing that. that the only thing stopping me from installing gages

 

[Prairie Dog]

I've heard a lot of guys drill the manifold w/o removing the turbo. How do you keep the shavings out of it?

 

[jjdiesel]

patience

Go real s l o w. Use grease on the tip of the bit to catch/hold the shavings. After your done, use a small magnet to fish any chips out that may have fallen.

 

[Task125]

well I chickened out. were do you drill? or does it really matter. looked at other posts and still confused. and it looks tough to get a drill in there with a regular bit.

 

[jjdiesel]

Where you drill is important. Don't know on an '03, have only done 2nd gen's. The one's that sold you the pyro ought to have a diagram as to where to drill... or perhaps someone here can chime in with a diagram.

 

[Task125]

I think I know where it has to go,the 03 flange where it connects to the turbo goes down,unlike 2nd gen that goes to the side,the problem now is to get the drill and tap in there.

Task 125

I drilled in the flange 2" above and 5/8" to the front of center above where the manifold is joined to the turbo housing. I used a 90 degree bit holder for the drill which worked out fine and in addition to going slow and using greese, just as the drill started to go through I started the truck which creates pressure in the manifold and blows any small particles out as you go through. I also worked with a friend on his truck and he wanted to install his sender in the manifold on top near the third runner which worked out fine also. Happy drilling. Larry

Boost numbers with the Bullydog Torque Dog are close to 40 psi. That is with a boost elbow rated to 35 psi. I wonder what I would see if I blocked it off?

 

[Prairie Dog]

When I tapped my 93 (I removed the turbo), I bought a new drill bit and tap as a set. Using these brand new tools made the job much easier and cleaner.

Diesel Power Products has instructions on their web site (with pictures) They drilled into the top of the exhaust manifold to install the pyro thermocouple. I don't know if this is supposed to be a better location, or more accessable. They recomended taping up the exhaust to create back pressure when drilling to blow the chips out. I bet activating the exhaust brake would do the same thing.

Our truck made 25-26psi stock.

Drilling Manifold

Best way I've found to keep the shavings out was to get a chunk of magnet from a craft store or like I did at sears and stick it on the manifold right by your bit. It catches all the shavings and if its close enough will magnetize the bit. Worked great for me both times. Make sure to use cutting oil on the bit, though. I know a guy who didn't and his bit heated up and he wound up cracking the manifold. Good luck



With the turbos, does anyone make a bigger housing??

 

[Ladders]

I just went thru at an angle in the forward down shaft of the manifold due to problem with getting the drill in there. . Seems to be working OK and no problems so far. Went thru at the inside bend of the e-brake (underside) for the after probe. Yes, I use both, and switch between the 2 for running loaded and shutdown temp. Try to hit 350* before shutdown but usually around 375* due to temps lately.



SOTSU!!
