Some may not remember but parish used to pull his equipment trailer with his old truck which had a pt88on a 408

 

George one thing I kind of fail to understand is how a turbo could handle long boosted runs any better than a procharger? I would think if anything the turbo would be victim to heat far worse seeing as EGT increases will directly effect the temp of the turbo itself. Do you think a turbo would have been happier with the same level of heat? I just dont see how its possible... the cold side of a turbo is so similar.

 

Which heat! Iat or egt?

 

Easy to answer if turbo wasnt meant to tow then no diesels would use turbos

A procharger is self contained oil
..once hot how will it cool?

A turbo oil is supplied by motor and most work setups using a turbo have oil coolers..so youre constantly running a cooler oil thru it

My procharger showed signs of heat

As for EGTs diesel vs gas...setup correctly with right tune and egts shouldnt be a concern

Ill have data coming up how my snail holds up

 

I would love to see this. I have been lead to believe that EGT's from a gas engine are much harder to control than a diesel under extreme conditions.

 

Every diesel thats hopped up has egt issues even unloaded

This is why those boxes say dont tow past level 2....have you been around majority of the ford made power strokes? Explain how just about every ford needs rebuilt in stock form from towing?


Hook a egt gauge up to a turbo gas and watch how much you can swing egts with tune

Most gas jobs use too small of turbine for towing loads

 

Yeah you have a good point there. I burnt a motor down towing with a turbo but yeah it was a tiny turbo lol.

 

The oil cooling makes sense to me. Good point.

They are still fighting an up hill battle being exhaust driven. The hot side literally collects heat and transfers it to the compressor. Turbo's run hot, plain and simple. Some of the IAT's I've seen from you turbo boys who are stuck in traffic is almost horrifying.

 

I've been towing with my tvs for the last few years. Only regret is I didn't do it sooner.

 

IAT at idle in traffic is hot with a blower...iats from turbo cant be high from not spinning compressor

Now with a metal intake youll have heat soak...cocaine for example heat soaks with IAT in intake by firewall

Example project blue lightning....turbo output for IAT was 250* IAT2 which is in intake is 100* after a full 1320 pull

So motor isnt seeing high iat like a PD blower

Same truck would see 198-220* with ice on a 1320 pass


Yes a turbo gets hot but still best route for towing otherwise factory vehicles would have PD blowers to tow


Id love to see a PD blower tow for 6hrs and 9000lbs
Open it up and see how bad the tolerances of case became

Wait i did see a PD blower that was used for towing...blower was in desperate need of rebuild...this was from towing a camper
