Towing with a 2.3t

[Davis]

wait till you split a manifold seam or lose manifold pressure due to your intercooler leaking, or blow the turbo because of excessive EGT. then it becomes like a potato in an exhaust pipe.

uhh, little correction. it's not because the turbo is a restriction. it's because the power difference between on and off boost is so huge that it seems like a restriction. also, turbo motors, both diesel and gas, are lower compression than a comparable NA motor.

exactly how often do you think that happens? LOL

thats like me saying that NA motors suck because they throw rods or spin bearings. the turbo becomes part of the engine system, if its built and tuned right its perfectly reliable... plus if you keep driving it with a blown turbo or leaking piping you're retarded

I think Big Dumb And Blue was speaking from his experience with diesel big rigs. He owns a trucking company you know.

Turbo gasoline passenger vehicles are a bit different than big rigs. Mostly in how many more miles the big rigs see.

lol...

It's like what therieldeal said if you drive with the same common sense you would in a non turbo vehicle that's not a problem. I wouldn't keep driving my non turbo truck if it was knocking, I'd fix it and drive my reliable turbo car while it's being fixed.

BTW Jon welcome to the scene.

With a big enough load the 2.9 will prevail at the dragstrip.

The 2.9 will lose less with more weight.

Say you throw on 20%, and the 2.9 loses 5% power, instead of the Turbos 30%....just showing what im trying to say here.

Its like a 302 Vs a 300....

Empty and empty, a 302 will cook a 300 in a 1/4 mile with 2 simialer trucks.

Hook 5000LBS and the 300 will be close, if not dead nuts even.

Hook 10000lbs and the 300 will chug a long and the 302 will be yanking its guts out.

Horsepower means NOTHING if you aint got the torque to get it rolling.

You have to turn RPMs to make Horsepower, how can you turn RPM's when your engine is stalling out because it aint got the TORQUE to twist the tires to get it rolling?

Even with a stick shift, you can rev it to 5 grand but by the time you have it rolling enough to full engage the clutch you wont have a clutch left, and if you relese it fast you just put a hellacious load on the engine and the engine cant TURN because it doesnt have the TORQUE.

the only time i see it being a problem is trying to get a HUGE load moving from a DEAD stop. once you're rolling fast enough to spool the turbo in 1st (pretty slow with a heavy load... the heavier the load the sooner your turbo will spool) you're golden.

turbo motors make plenty of torque, even at low rpm. did you miss that part (again)?

once/if i get this project done i'll take it to the dyno and i'll have them start the pull from idle.

i would tow with a 2.3T i had my old turbo coupe getting boost around 2900rpm and going sideways all the way till 4000 rpm plenty of TQ if it can move the T-bird around like a rag doll i would say you can tow with it... as far as the 2.9L out towing a 2.3T dont think so....

 

[inferno94]

It's all about the sizing of the turbo and how the motor is built. If you put a huge turbo for the size of a motor it takes longer to spool and make boost, ball bearing turbos help this but don't fix it.

With a big enough load the 2.9 will prevail at the dragstrip.

About 4 years ago a man named Dave R (the vets here will remember him) ran a 2.3t at a dragstrip. With a t-bird in tow. Something like 9600 GVW. He ran a about 19.50 in the 1/4.


I doubt a healthy 2.9 could do it in 16.99 with no load.
You think it could do it in 19.50 with another 6000lbs tacked on?

Where are these numbers coming from? They don't make sense. It's like every time you think you're about to lose an argument, you just make something up and try to justify it.

What is this nonsense about losing 5%, losing 30%, etc? This whole concept is SIMPLE. Look at the engine output. 2.9 makes a certain torque curve across the RPM range, 2.3t makes a different one (adjustable based on configuration). It's not that complicated. And they don't CHANGE based on what is attached to the back of the truck, whether you want them to or not.

 

[therieldeal]

well in a way they kind of do change but not in his favor... as we said above - the heavier the load the sooner the turbo will spool, giving you even more bottom end torque than you'd have without a trailer.

 

[rusty ol ranger]

Those wernt actual numbers, just numbers i used to make a point.

Bigger engines tow better, rotateing mass is rotateing mass.

I realize that the torque curves dont change with a load, but the 2.9 has a better torque curve for towing then a 2.3T.

You'll never convince me otherwise.

So what he really needs is a super heavy flywheel and his 4cyl could tow a semi?

BTW those 2 points above don't have much to do with each other.

 

[Captain Ledd]

So if I may jump in here. I've kept up with most of the thread and I don't think this is necessarily hijacking it.

So if you were to tow a pretty heavy load a long distance with a 2.3T, there would be a heat buildup in the engine, and getting a slightly larger radiator would help alleviate the problem. Would it also be a good investment to try to track something down like a high volume water pump as well?

Yeah I'd love to know where those numbers came from too. You tried to make a point, but those numbers were so damn random no one understood it.

I think it's safe to say that your lack of knowledge in turbo basics severely limits your understanding of just how MUCH more capable a 2.3T is than a 2.9.

If you took the time to even learn a little bit of turbo basics, no one would have to convince you of anything. You'd convince yourself.
