Non turbo engine converted to whistler, safe egt and boost?

[Cummins_12v]

Hello, bought a new deuce today. The last owner converted it to a whistler turbo. It smokes nothing as it is now, and not much more power vs my old cranckedup(heavy blacksmoke) non turbo.
I dont have egt gauge yet. But i have a boost gauge in my garage that i propably can install tomorow.

Where to connect/drill to the boostpressure?

How much can i safely turn up the pump with only the boostgauge?

I want to drive safe, witout blown headgasket etc. It a non turbo block.

I would ask the previous owner if he reset the timing for the turbo.

That would lead to power problems if it were not set properly.

Anywhere post turbo is ok for the Boost gauge.

Timing is stock non turbo , but thats just fine. When turning up the cumminsengine i have, timing is also advanced. Where is the best place to drill? And do you drill whith engine not running, and use grease or what?

Boost is mearured on the intake side. Pull the big tube that runs to the intake from the turbo and drill and tap it and then clean it up and put it back on.

EGT is in the exhaust stream You can go in the manifold, or else after the turbo. I did a study on the differences in temperatures and there is a predictable drop accross the turbo. 100 F is average.

Or, use the pipe plug on the intake 90 degree elbow(where the ether start kit connects).

To be safe(with only a boost gauge) keep it under12-14 psi boost.

Thanks guys, so 12-14 psi is 100% safe to not get a meltdown, and not a blown headgasket?

The headgadket on non turbo are weaker the td blocks ?

If you want me to say your 100% safe, I'll tell to to stay below 10psi.

Remember, if you increase your load, everything will change.

Not sure what you're asking. Do you have a TD block? Do you have the "old style" head gaskets or the "new style" gaskets? Old ones have a visible "weep" tab , on the passenger side.

What is wheep tab? Its a m621 1968 model. Delivered to the Norwegian army, single wheels, lockers etc. Its not a td block, and the turbosetup is taken from a m35a2. thats why im wondering if this block have a weaker head gasket?

Old style head gaskets and weep channels are visible in post 2 pics 5 & 6 http://www.steelsoldiers.com/deuce/10460-head-gaskets.html

If you do an Advanced search, in the Deuce forum, for "head gasket", there are a bunch of good threads.

Just to let you know, some non-turbo trucks have TD blocks. That casting means they are thick deck blocks. Not sure what got more material, but something did.

The gaskets WERE all the same with fire rings not attached to the gasket untill the new style victor reinz came out. It has nothing to do with the turbo/non-turbo.
