welded engine mounts... still need a flex section?
 

so, Im going to weld the mounts on my engine and tranny on my 96 escort when I boost it, do I still need a flex section in the exhaust? Im guessing no... dont really see why I would.

Re: welded engine mounts... still need a fex section?
 

Welding any two points together which were formally connected by a flex point/link doesn't sound like a good idea at all.

Re: welded engine mounts... still need a fex section?
 

i would add a flex section just to be on the safe side.

Re: welded engine mounts... still need a fex section?
 

what the hell?! you welded your engine mounts?????

Re: welded engine mounts... still need a fex section?
 

Weld the mounts solid?

Vibration is annoying, but the engine becomes part of the frame, adds stiffness. You see it a bit with domestics.

Re: welded engine mounts... still need a fex section?
 

i see those welds cracking in less than a month~

a v8 has more points to weld... well, not really... but they're torque isn't adjacent like the tq on fwd transversly mounted motors....

i mean:
our engine mounts if welded are trying to stop the twisting...

V8 engine mounts are trying to stop lifting.. its not like they're mounts are inline w/ the crank (only the tranny mount would be)

but hey, let us know how that works out.

Re: welded engine mounts... still need a fex section?
 

Uh, no. RWD engines twist pretty hard... they turn the driveshaft one way, and the engine tries to move as Isaac Newton tells it to.

Re: welded engine mounts... still need a fex section?
 

lol. to try to stop lifting? ha. v8's lift? and why would they do that.

Re: welded engine mounts... still need a fex section?
 

i kept breaking/shredding motor mounts in the accord and got soo pissed off i just welded my front motor mount solid, and all the other ones were filled/braced back together, im gonna weld prolly the rear tranny mount solid too. Its not that bad, it just makes the dashboard vibrate to kingdom come.

Re: welded engine mounts... still need a fex section?
 

I havent welded them, yet. The escort is terrible for wheel hop and welding the mounts nearly eliminates it. Im also planning on whipping up some kind of traction bars this summer, if the funds allow for it. Ive decided not to be a cheap bastard and buy a flex section. Ive spent money on every other ------- thing, so why stop now! :P Id also hate for the exhaust to crack my imported escort RS turbo manifold from the UK, that took 2 1/2 months to get here and still cost me $100 to ship.

Re: welded engine mounts... still need a fex section?
 

im just thinking that if the engine even twists the mounts a little bit on a hard launch, that little bit of movement can put alot of leverage on the exaust manifold if the entire exaust doesnt move with it, youre better off so it wont crack or anything in the long run

Re: welded engine mounts... still need a fex section?
 

yeah, it would really piss me off to crack my manifold, those bitches are hard to find in the states. I had to import one.

Re: welded engine mounts... still need a fex section?
 

1- im not a noob~
2- in a FWD car, the forces of engine torque are leveraged on the motor mounts in a twisting fashion, where as in a RWD car, they would be pressure and lifting force... Heres a quick drawing..

Personnally, i wouldnt weld my motor mounts IMO. (fwd honda)

but if you are, deffinately get a flex section. Remember your hangers will give a little bit too.

Re: welded engine mounts... still need a fex section?
 

Im still going to weld them, because when I start feeding 200+ HP through a tranny designed to hold 88, Its going to need all the help it can get to survive... The escort tranny sucks to begin with, let along when you start hammering the ---- out of it. Im also going to get a flex section as well.

Re: welded engine mounts... still need a fex section?
 

yeah exactly.. v8's dont lift ::) they twist just like you drew.

Re: welded engine mounts... still need a fex section?
 

who would have thought that pressure upwards on one side of something and downwords on the other side would create lift??!! :1

Re: welded engine mounts... still need a fex section?
 

I've seen a lot of Pro FWD cars that use solid mounts. They don't break. If this is for a daily driver, I would refrain from having solid mounts. The vibration would get annoying after awhile. You should just fill them with urethane.

Re: welded engine mounts... still need a fex section?
 

Im still going to weld them if the vibs are too much of a PITA, I've got a spare set of mounts laying around.

Re: welded engine mounts... still need a fex section?
 

Smart guy~ one side is bolted... and is holding that mount from lifting... and the other side is bolted down... holding the other side of the engine... niether of these mounts succumb to any Twisting force at all. The i4 motor mounts are preventing twisting, because they are located in the center of that tourque~

BUt ya man, go ahead. vibratin is fun, have ur girl hold ur shifter... an watch her bite her lip an close her eyes~ j/k man :4

Re: welded engine mounts... still need a fex section?
 

unibody cars made from sheet metal and solid engine mounts dont last,most V8 cars have real frames or at least subframes. Get a welder so you can mig up the cracks, I love people that look at race cars for there street car ideas ::)

Re: welded engine mounts... still need a fex section?
 

Mabye on your honda, but I know of 3 people that run welded mounts on escorts on a daily basis for 3-4 years with no problems.

Anyways, its my car, why should I have to justify what I do to anyone.

Re: welded engine mounts... still need a fex section?
 

i say ---- it, weld them up. Id rather go fast and have vibration then suck, welding them helped with traction and shifting consistancy too, since there is virtually no torque/shift rod movement all around, you can nail shifts easier. Havent you guys ever seen big v8 cars twist their chassis? Most of them are pretty weak, and dont have a full frame either, so they use subframe connectors and roll cages and other reinforcing measures. Most serious drag cars have one hell of a built/reinforced rearend/axle/suspension.

Re: welded engine mounts... still need a fex section?
 

thank you! I have 550 lb springs in my car... if anything is gonna crack the chassis, those bastards will, god damn does it corner good :1

wow, I jusat realized Im adouche and misspelled "flex" in the title. ::)

Re: welded engine mounts... still need a fex section?
 

ok im going to answer some questions for you guys here.....

welding up a set of engine mounts like this picture will decrease wheel hop and eliminate motor torque.

i ran my mounts like this for over a year. not one issue ever came of it. the car didn't vibrate to hell liek you all are willing to claim it will. it shacks a bit more on start up but the idle and driving was no different then stock. this was due inpart to a couple reasons.

1. i have 4 motor mounts.
2. i only did my front and rear not my passenger or driver side mounts.
3. not doing the side moutns helps the vibration be defeated.

i ran no flex pipe. my stock style rubber donut hangers where enuf of a flex in the system to combat any vibration or wobble caused by the motor and its acceleration torque. <-- there was almost 0%. if i shook my motor the car would just roll back and forth.

i saw cleaner shifts and less whel hop. even with my car lowered it still liked to hop before i did the mounts. tho its less with the lower. the combination of all these things made the car hook up better and keep teh tranny in one peice longer.

but hey what do i know i drive and escort! <-- ---- you if you think like that!

Re: welded engine mounts... still need a flex section?
 

i know, i like my welded mount. Having big movement in your mounts is inviting somthing bad to happen (broken axles etc) my car vibrates noticeably more but welding mounts worked wonders.

Re: welded engine mounts... still need a fex section?
 

the mounts you drew in your photo arnt even the ones that keep the engine still. they just hold it up. are you forgetting about the lower mounts?

Re: welded engine mounts... still need a fex section?
 

Neuman for the win!! LOL, thanks for the backup Neuman. :P I didnt know you only welded fronts and rears, I thought you did all 4. Thats good to know before I whip out the mig.

Re: welded engine mounts... still need a flex section?
 

they sell them for my stang
