Howdy ya'll. It seems to me that there is a huge facination with turbochargers on a 300. I got this crazy idea as i was driving by a Semi Boneyard. Why can't you use a Turbocharger off of a Kenworth or Peterbuilt. I am no trucker but i thought one of you guys might know something about them. If more boost means more power, lets get something that makes more boost to get more power. I don't know how hard it would be to do but this is just an idea for you guys to tinker with. Enjoy.

 

well in most cases the ones off a semi are gunna be pretty darn huge and won't fit the 300 very well. It would have a tough time spooling it. Looking for turbos off of smaller trucks like diesel dump trucks and such would make sense though.

 

I've discussed this with the local turbo guy and he recommended the turbo from a mid 80's turbo Regal or Grand National. The unit from a Powerstroke or Cummins might be OK too, but slightly on the large side.

 

Ah come on we all know that bigger is better. It would be an interesting project to build. Who wouldn't want to see an I-6 smoke a Camero? (whoever answers no needs to move to the chevy site, oh wait there not smart enough to make one as good as the FTE!) Ok guys It was just a random idea that seems like a project for the Ford Truck teams.

 

hehe, well in the turbo's case bigger isn't always better. The larger turbos are better for high end power because they can get a larger compression, but they need more exhaust pressure due to their size. A smaller one can spool up a lot faster and at much lower rpm, but it can't yield as much boost, so its not as good for top end power.

The I6, i believe, would benefit the best from a mid to small range turbo. It's already got all the power it needs at low rpm, it just needs to be able to hold its torque once it gets revving high, which will yield horsies, which we all love.

On the other hand if you put on a small turbo built for bottom end... well you would have a beast.

 

whith big deiales the turbos would run WAY too much boost for a 300. Most of them are actually running in the mid to high 20psi range. That alone would wrek that motor and the fact that you would probly have to hit 5000rpm before there was enough presure to spool it.

 

So Rhetor your telling me if i stick a small turbo of a Buick or Other small car i could get a truck to do wheelstands? or maybe just get the front to get off the ground just a little. Now that beats anything a ricer puts up, a 6000# truck jumping in the air.

 

maybe im wrong but being that the 300 is most powerful at lower rpms would it not be better to super charge??

there is no spool up it starts creating boost the minuite the engine is started and continues to boost through the entire rpm range

just my opinion but wouldnt a turbo be better suited for a higher reving engine that can give more exhaust flow


just pondering the question at hand

A supercharger would be OK, but it is far less efficient than a turbo. A blower also doesn't necessarily make full boost off idle. A centrifugal blower has to have rpm to make boost just like the turbo does, the difference is that the centrifugal needs engine rpm to make boost and the turbo needs impeller rpm to do it.

A properly designed turbo will have no lag to speak of and make good boost throughout the rpm range.

 

and also, getting a blower on a 300 wouldn't be very easy.

Getting an 18ft pickup to do a wheel stand is no easy task. First you would need massive amounts of torque, probably upwards of 400-500ft.-lbs at a low rpm. Now, sending 400-500ft.lbs of torque to standard tires just won't do, so you're gunna need some 18" wide drags on the back there.

An also, if you were in a truck doing a wheel stand and you were not in a monster truck rally, you must be crazy.

 

dosent sound crazy to me sounds fun

 

so what would be an optimal setup a staged twin turbo system set up to kick in at like 1500 rpms and again at like 2200 and then a 250-300 shot of nitrous to keep things fun

 

actually my 300-6 is bored 40over and will almost pick the left front, if i put it in low gear it will pick it a good couple of inches, realy fun and scares pasengers. Oh and they are now making belt driven turbos which will give you more imediate power but this will also climb whith rpms and still uses exaust gas thus saves a bit of gas too. One of the Macks my dad works on has one and its perty cool.

 

Bolt this in, hehhehehe:

ah, just what I need for the Subaru I picked up- what is that, an EMD? Or is that a GE diesel? I am repeating myself, and probably will continue to do so- Two small turbos, with EFI. If you guys can just hang on for a little while, I can have one of these things built. If you need actual information sooner, I am accepting donations for my Turbo Fund.
