DSM Fail: Tranny Drops at 120mph

[Sweed]

Hope it embeds, but here's a video of a DSM that has the transmission drop out of the car and the clutch fly out the front at 120mph...

Colt+tranny+drops+at+120mph+!

Haha bunch of *******es.... better hope he has a parts car sitting back at the shop.

[XMDrifter]

saw this on streetfire. lol it was funny.
**** needs a built transmission.

[Bananabrain]

I thought that was funny when he was saying there might be a fire.......Get-out....get-out....get-out & the guy holding the camara is taking is sweet O'le time lol.

Sucks for them. lol

human error flywheel bolts where not torqued. But why did the tranny let go from the mount?

[texan_idiot25]

It's a 500hp Mitsubishi Cult, running some 40+ LBS of boost. **** will blow up! As to why the trans dropped, maybe the whole thing was mounted at the block, and not the trans?

But, to explain the failure, a DSM fan stepped in at Jalopnik to share some humor:

07/22/09

In order for a Colt to make that much power, it must have been 4G63T swapped.
To build a 4G63T to that much power, and to swap it into a Colt, he must be both a DSM freak (to build that motor) and a true Jalop (to stick it into a Colt).
DSM freaks like to build power, and not upgrade the drivetrain until something breaks. When you buy a DSM project, you can assume that eventually you will have to replace everything. Every single thing. Each thing in the car, you will have to replace. In the mind of a DSM freak, there is no point to upgrade the transmission until after it breaks, so you may as well have some fun pushing X amount of HP through it, where X is a number between 200 and 1000.
This grenaded tranny is considered a "forced upgrade."

the flywheel clutch and pressure plate all came loose and broke the bell housing. I'm guessing it was just some dumb newbs. I dout it was even had 36psi of boost. Plus at 120mph and the tranny coming apart I'mk sure that thing would have floated a valve, it seemed to still run.

[texan_idiot25]

It runs 40+ psi of boost, there's plenty of dyno run videos to show it. The car just doesn't make much until it's really revving, it's a quiet turbo in the videos.

I think it broke during his shift, when I watched it... Wouldn't be hard to find this kid on the net, just gotta hunt down a 500 hp Mitsu Colt, and how many of those are there? Blaze him with questions

[TheB1GDude]

40+ PSI boost just seems insane to me on a car like that but then I don't know whats under the hood but on that car with stock motor I wouldn't push it past 18...

Tex I'll bow to your greater knowledge on this as I'm sure its possible after all stock Mustang block is rated to 500HP.

As for why I'd say as the bolts hadn't been torqued he dropped the clutch, they sheared he bought the clutch back up and it came up sideways....

Block or bottom end (piston/rods)?

[TheB1GDude]

bottom end sorry.

I don't know anything about the stock motor, but this looks like a DSM motor (Eagle Talon, Mitsu Eclipse, Dodge-something-after-the-Laser), which tend to take a lot of chit I've seen. But, alas, their not my thing so I don't know much on their limits.

[jimmythekid1]

I just watched it again. Look closely at the the fly wheel and bell housing the only place flywheel and clutch are blue it were the wheel contacts the crank. The bell housing also has scrapes were the fly wheel machined into it. The bolts may have broke but it had nothing to do with the engine.

[TheXmodifyer]

When my brother bought his 64 galaxie it had a 390 in it. We built that 390 up, dropped a borg-warner super T-10 4 speed in. Split tranny and bell-housing. For this exact reason, we run a scatter shield.

I'm a DSM expert. I've owned one for 8 years now. I have a stock 4g63t (same motor they upgrade in those colts) in my Eagle Talon and I run 20psi Daily on an ENTIRELY stock motor. To run 25 psi all that is necessary is an upgraded headgasket because the stock one gives out around 22psi.

Keep in mind the DSM powertrain the 4g63t is essentially the same as the earlier evo motors from japan.

Though, While engine might be stock, you must keep in mind that its necessary to upgrade exhaust, bov, intercooler, fuel pump, turbo and injectors (hence with injectors, a tuning kit will be necessary) to run a lot of boost.

These cars boost 11 psi stock. A light colt with one of these 4g63 is maybe the most amazing sleeper on the streets. An engine known for easily making 400-500hp in a 2000 pound car? Its like a honda with a motor swap on steroids. Not to mention that the colt is a particularly crappy looking car lol.

22psi on what turbo?
Becuase 22psi on a stock 14b is not the same as 22psi on a t3/t4 or on a much bigger turbo.

Your right its not, but the answer remains the same for the most part. Detonation is the real destroyer of head gaskets, with a good tune I'd say either. 25psi is just a rule of thumb, some dudes bring their stock head gasket all the way to 30psi on big turbos like Mitsubishi TD06H 20gs.

I personally have an evo III 16g, its a 550cfm turbo. I tune with ECUplus which has an extensive logger and is very nice.

Anyway, here is a good thread regarding DSM and their headgaskets... http://www.dsmtuners.com/forums/bolt...ad-gasket.html
