I would suggest you run an intercooler regardless of the meth. It would be much safer at those boost levels, especially towing. I wouldnt run over 6lbs towing without one.

 

I agree here. Intercooler will help a lot with towing. Also coating and wrapping the hot side should keep the temps down to a safe level. Having a bit of a lift might also help with getting air flowing under the truck a little more and help temps out. Sounds like a good setup overall though

 

I already planned on having the cast iron manifolds and the turbine exhaust housing ceramic coated in/out. I am also planning on wrapping the hotpipes and the section of the downpipe that is inside the engine compartment to reduce underhood temps as much as possible.


I am not buying bigger injectors, so if I start breaching 85% duty cycle, then I'll just back the boost off until needed. I still doubt I am going to bother with an intercooler with something as mild as this. I guess time will tell and I can always add an intercooler later if need be.

 

Who will be tuning for you? I would make sure you have a really safe spark IAT table, because you are going to heat soak the **** out of everything from your turbo to the TB when towing without an IC and that can get dangerous.

 

I'm pretty sure Kurt Urban tows with his turbo truck a LOT (something like half of its 138,000 miles) with a car trailer.

 

As others are telling you, no intercooler is a really really really really bad idea. No intercooler will take away any power that you gain.
You have to pay to play. I think that if you can not afford to do it right you are wasting time and money and will end up disappointed.

I fail to see the issue with using a meth/water injection to chemically 'intercool' the intake charge....

I understand you guys are trying to help and its not a bad thing, but I'd rather find out if its REQUIRED before going through the whole 'song and dance' only to find out it really wasn't needed.

Again, thanks, but my primary question was about the turbo size, not intercoolers/injectors/etc.

 

For the pure fact that you will have to keep buying meth over and over again, why wouldnt you put an intercooler in? You only pay for that once and will do what you need it to do all the time, without worry of failure! I dont plan on running meth on my truck untill it sees 12psi or more and that will only be setup for track days.

 

The same goes for gasoline, gotta keep buying it over and over again... :-D
