why not just run a pyrometer and keep a close eye on temps and run a safe tune and then tow whatever you want?

 

Lol, exactly, but that would be to simple.....people like to complicate things for some reason. . Gives me good entertainment though....hehe

 

69Fire, we aren't trying to get a motor for nothing

 

BTW, the 2JZ is great but their is another inline 6 Toyota that I think will probably be the wave of the furture. The engine is big cubes...4.5 liter and its a DOHC engine as well. I will hopefully have one soon, as they are somewhat hard to come by as well. We have alot of customers overseas in different countries and these guys are already hitting the Toyota motor hard and making HUGE power. BTW, here is a some shots from a customer of mine. He owns future generation MS in the middle east. They build some wild rides....here are some phone camera shots....so they suck, but at least you can see what the engine looks like...





With girdle and partial block fill, you will probably see these engines reach 1800-2000hp.

is that motor going to be comming state side potentially? possibly next generation supra?

 

Ed give me a # to call you at .

 

I cna definatly understand them saying dont use it for towing. Cuase 99,9% if people that buy FI dont spend the 1k for a laptop and hptuners or ls1edit. So they will be running thier power tune all the time. And that woudl make from some bad news. Unless they are running a extremely safe tune. If you dont have forged pistons wouldnt the heat from a 2 mile hill put WAY too much heat in there?

That engine looks like its in a tacoma. Prolly a fast *** truck lol

John, if someone is not smart enough to tune it and blow it...then that is not a system and design flaw and hence no reason when properly tuned it can't be done. As for pistons heating...why sure, they absolutely will, but that is what the tune is for. Just watch the EGT's and you would be fine.

BTW, that engine is in a Landcruiser/Lexus.

 

if i was selling a front mount turbo kit i would tell everyone to tow at your own risk. many people will just bolt the kit on an give it hell, thats just how it is. many people do know know what knock sounds like.

the first concern would be the header, it is made of thin wall stainless, i dont think it will hold up to extended periods of high heat. if the kit used the stock mainifolds then maybe.

 

how bout 950 on pump with a trailblazer I6

 

I would just supercharge it. The turbo, while under load is going to be in excess of 1000 degree's I would think. I'm super keen on the idea of running 1000 degree motor oil through my engine for several miles/minutes at a stretch. Diesel's use a different oil than gasoline engines, maybe that's part of the reason?

 

what are the specs on that trail blazer?
that looks like an awsome setup would be interested in the particulars.

doesnt look like a street kind of build looks more raced out
would be interested

 

There is a simple and obvious reason for recommending that you do not tow with these kits. People won't take the time to load a "tow tune" in there every time they want to put the trailer on. No amount of heat wrap or pyrometer watching will matter on a grade when pulling 7-10K pounds on a 90F day, after being on the road for a few hundred miles. Something will melt or the 4L80E trans is going to spit chunks. Halfway up the hill with the load is the wrong time to be saying... "ooooppppssss".

All you have to do is look at every plug and play kit or PCM tuner for the diesel trucks. They all have a tow settings that are about 1/3 of the max power and way down the list on the relative EGTs. Even the guys with built Allison trannies don't run around towing more than one setting above the "tow setting" because the EGTs are still dangerous over the long haul and rough grades with a load.

Can you beef up the intercooler, the radiator, the fans, heat wrap risk areas and have separate tunes for racing and towing? Could someone do the tow testing to find the right power level for these trucks with a stock tranny and a 7-10K load? Sure... but that's not included in a standard gasser turbo truck kit at this time.

The current kits are built to be deadly sleeper fast fun and they do it well.

Aye, good point... you know they sell those kits to some Joe Schmoe's who just want a faster, more powerful truck and know nothing about the limits of their vehicle's engine.... and let's face it, it's going to be MUCH easier to cause turbo-induced damage to your engine and trans when you're towing than when you're empty. And do you think they want to load a more conservative tune for towing? Please! the only "tune" they know is the **** on their radios!!!

 

A friend of mine has a whipple on his Suburban. His only complaint is that it is in boost all the time when he is driving on the highway, and it is killing his gas mileage. I would think that towing would keep you in boost all the time. As soon as you go into PE mode, you are dumping a lot more fuel in.

What if you wired opened up the wastegate while towing? Would that make a difference?

I haven't checked this post since Friday and there seem to be a lot of different thoughts. Now I see a comment that a whipple seems to be in boost all the time in a Suburban. This would not be a good move for my dad because that would cost him the gas mileage that he needs to keep. I thought Whipples had bypass valves on them & were only in boost if you put your foot down on the go peddal to much?

Sounds like if I go with the turbo I would need a tow turbo tune and I would need to check what grade piping is used so that it would not get to hot as well. Also turbo wrap, pipe wrap, and egt gauges would be a must also. Thanks guys for all the info. If I had it done I would have it tuned at JD's Auto in PA here, I guess I would just tell them my needs and tell them I want a safe tune for towing.

 

I would hate to argue with the only person who knows turbos on here but the fact remains, these cars/trucks do not come with turbos, their engine bays are most of the time cramped and not designed to handle the excessive heat developed over 20 MINUTES or more of constant FULL THROTTLE. I obviously did not say the turbo itself would have an issue, my point was the turbo, relating systems, and the hood of the vehicle COULD melt or burn up from HARD towing, a blanket would sure help but I still don't think it would be as good as simply placing the turbo in a cooler area. The STS system works VERY well and I have personally seen many kits now making full boost at 2800 or less RPM especially on a larger 6.0l or the like. And yes the diesel engine does create lesser exhaust temps compared to a gasoline burning engine of the same torque capability....just for your personal knowledge.

Too Bad we can't put the entire Ocean/Lake into our radiators, then we would be able to tow with 1000RWHP and run cool all day long!

 

Yea, I was thinking that too... marine applications (ie powerboats) usually run A2W intercoolers and can easily achieve cooling efficiencies over 100%... especially with the temp of the lake/ocean water pretty much always being well below ambient air temp. I am sure that helps you keep it at WOT for extended periods of time!

Also, in a scenario like that a more conservative tune would be the norm, right?

 

Ok I am a little lost hear... I drove with a supercharge on my 93 pulling 7800 lbs, up down the road no issue, except in the heat would take a little more time to get up to speed but thats it.. Once there set the cruise and only went into boost if I hit a hill (not a small one either) somehting that force the truck to down shift... Now the 6.0L has a lot more pulling power then the old 5.7 did, and I think a better transmission.. I know there are a ton of coolers on this truck, engine oil, 2 trany coolers, and of coarse a radiator...
I would have to say if the vehicle is always in boost while pulling, you need a bigger truck, or you are over loaded...
I have not hooked a trailer to mine yet with the turbo so do not know what the heat is going to get to.
But you have to ask the question is this a tow rig or a race truck, two total different worlds.

STS I have "0" experience with but its in a cooler place, and if you can create the same power level back there @ the same rpm I would go with it if I was not so hard headed and built my own.
