Default tC engine capability for hauling heavy loads

I noticed the tc has an aftermarket towing part capable of towing a ton of weight... i'm doin somethin different and want to make sure this will work.

I compete with this vehicle stereo soundoffs.

The last install i had weighed in at 560lbs and the car was fine with the install for about 8 months before i tore it out and ready to rebuild.

The new design is gonna weigh in at around 1,300lbs.

I am workin with a distributor to get a custom quote on an easystreet air ride kit installed on just the rear of the car.

I've already got high payload tires (over 1,400lbs per tire) and upgraded brakes.

I've been told that is may be "possible" that the added weight may create havoc on the transmission...

Now, as long as I drive it normally and not race the engine.. i'm assuming that's fine.

I am having a custom alternator built for the vehicle that is gonna set a record for the largest alternator for 4cylinder cars ever... It's strong enough to literally break the crank so they are workin on attenuating the horsepower drag so it can still run stable on the car.

Due to the added demand off the alternator, it's obvious i can't put a load on the engine from the alt with this much weight in the vehicle.

I'm postin this to ensure that everything is laid out and planned to support the weight and the drivestyle of the vehicle to ensure that their won't be near immediate problems that may occur...

I've had 900lbs of weight in the vehicle for a couple weeks at a time before and i can tell the transmission doesn't like being raced as it has a drag on shifting gears. that's fine with me as i don't race the engine anyways, just cruise. (makes me wonder how u can tow a ton of weight as advertised from the company that manufacturers the hitch for it)

I don't get why people buy a scion with the intention to tow ____. Get a truck or something

Those bolt-on hitches are usually just for hitch-mounted bike racks, even though they claim towing capabilities.

I wouldn't even bother to try towing anything on a scion. You'll regret it.

from my understanding he is comparing towing to weight he can add to the trunk of his car with some massive system.
i dont think he's trying to actually tow anything.
a 1300lb system in your trunk is crazy sounds like you need a suv to fit alll that junk in yo trunk son!
what r you going to run btw?

OK, well lets throw that anology out then. The equipment isn't being towed, it's in the vehicle itself.

From what i gather, air ride suspension allows all the added weight to be stressed on the air struts itself rather than the axle, tires, etc..

So, in regards to that, i'm assuming the engine shouldnt have a problem with moving this much weight?

I know this isn't a direct comparison but a buddy of mine has a jeep cherokee, 4.0L v6 and he has his vehicle weighed in as moving an extra 1,567lbs of weight for about 4 yrs now for competition and has never had a problem nor does his engine drag... He actually posted a 10.6 in an 1\8th mile run with that weight.

I am the first person in the world to ever walled a scion tc before.

I am also trying to be the first person ever with this car to break a world record in my class...

The car has 4-6 16v batteries, over 32,000w of power and a 900lb enclosure made out of concrete

Stick or Auto tranny? Auto sucks. Put in tranny cooler if you are auto. If a stick, then get a better clutch (Exedy Stg 1). The RAV-4 is capable of towing and it has the same motor in some years...

It sounds like you already know more than we would about it anyhow. Just do a little trial and error but more specifics on what EXACTLY you are trying to accomplish will help us help you.

basically, i was told that some people are worried the transmission is gonna fail due to all the weight in the vehicle. I drive an auto, never heard or thought about it, but don't really see that happening.

I figure i would do what i always do and trial and error as i go anyhow.

If i feel the tranny continuously dragging, shifting harder than normal, slipping, etc.. then i'll look further into it.

well towing a 1000 pounds of weight is different then putting a 1000 pounds into a tc.
Trucks have two ratings, towing and payload weight. What your trying to do falls into payload weight which is alway less the towing capabilities.

well, this distributor that's workin with me on gettin a custom quote for rear air ride suspension said that's what i need is air ride. It's the only thing out there that exists for this car and would alleviate any suspension problem that could occur without it.

yea i know, hehe. when i had 550lbs in there... the stock brakes were terrible!

I got Hawks brake pads on right now. I'm probably eventually gonna need to upgrade to SS brake lines.

The auto tranny doesn't hold the load of turbo past 250 hp so adding a lot of weight to it and going uphill may simulate the same load condition. I still advise putting on a tranny cooler. They do make a brake relocation kit that moves the OEM calipers out further and gives you a bigger rotor so it's half the price of a big brake kit but provides much more stopping power than upgraded pads and rotors. Just a few things to think about.
