Outer Limits 4x4 Board

Hi all , has any one here ever braced the top of a 2H in a HJ75 as they seam to loose quite a lot of there torque through the low standard mounts flexing .
Of coarse if i have to fabricate something i will soft mount it to save fracturing anything , just wondering if anyone has already done it and how much better or worse it became.
Please keep in mind my 2h is fitted with a Turbo and has 2 cross over pipes .

Thanks Andrew

who told u that?

No one needs to tell me, i can see it in the fact of when under load etc it will torque the gearstick towards me etc .
So i believe that if the top end of the engine was braced it would be able to transfer all power to the wheels , not looseing it in the flexible mounts.

I recon you'd be better off making more rigid/stronger mounts to replace the factory mounts.

try and find a way to put a Engine Tourqe Damper on it

Ok , where do you get e'mm

try ebay or most performance shops will sell them

Are your engine/box mounts in goood order and tight?

Mine are, not sure about Andrew's!

I really don't think it's necessary - i imagine the amount of torque loss would be comparatively minuscule

there would be no torque loss, just a miniscule delay in the torque.

For there to be torque loss you would need the engine to be spinning.

Well yes the energy is 'regained' when the motor rotates slightly back into it's idle position - but this would kinda be wasted (as the intention of the driver would be to decrease rate of acceleration).

Still - negligible especially in this application! I think torque dampeners are more to protect the engine mounts from high torque impulses (or sumshit )

i dont mean regaining energy

sure, it will sap the torque briefly to rotate the engine against the force of the engine mounts, but once the mounts are streched/compressed, the torque the motor is producing is ALL going through to the driveline.

So for the 1/2 of a second it takes to load up the engine mounts, your torque probably is reduced (by how much??? insignificant IMO), but once the engine has rotated slightly and loaded up the engine mounts, all torque goes through the driveline.

The only way to fix this, is to solid mount the engine, and that will destroy your car. A 2H at idle is not a smooth thing!

I was agreeing with you - but it's too late to be thinking too much about this shit

The engine rotating back into it's original position is also producing torque - which can't really be harnessed

Holy crap dudes you 2 are really bored arn't you , mabey i'll ask a question about the space shuttle next time .

well you did ask a slightly ridiculous question. Almost every car i've ever driven in will flex the engine slightly under acceleration. Even pissy little four bangers. They are designed to do that as it limits vibrations and the encumbant fatigue to the chassis.

The only time i have ever seen an engine braced or hard mounted is in race cars that have so much torque the engine wants to rip itself clean out of the engine bay. If you can get a 2h to do that then give me a call and i'll finance your new performance business

PLEASE do the the world a favour, if you have that much money to waste on a pointless exercise...find out how much it will cost you to do the job and instead of doing it ,write a cheque to some worthy charity where your money will be much better spent
