any motor moves like a mother if the mounts are shitty
don’t think even Hans Stuck would know every shift point in an 09 Viper ACR on the ring…
Big engine with crappy balance or smaller engine with good balance, whatever, the driveline shouldnt shake around like that. Improve the design.
Hans Stuck could manhandle that thing around the Ring. Dude’s the man.
bite your tongue.
I dont really think it has anything to do with balance. I think its just the V engine design that makes it "rock or “torque” back and forth like the way it does…even my V6 under boost would torque almost 3/4 of an inch side to side.
between a V designed engine, and a straight line engine…its common since in which one would/should rock/torque more.
It has a lot to do with balance. Engine balance determines how much an engine wants to move under load. V6s have horrible balance (dont many V6s still require balance bars?). V8s are better due to being longer. V10s even better and V12s are excellent.
Most inline motors that arent transverse mounted need fewer mounting points than a V motor.
It’s not a knock on V motors; there’s a reason they are still widely used. They just need to be held in place better than that Viper’s is. I’d bet money thats just lazy, shitty Dodge quality and engineering.
it seems like that viper just has a very rough limiter. im sure with a solid, or urethane mount set it would be better, since the car is street legal, although “race prepped” i dont think everyone one who buys one wants their teeth to rattle out from the rigidity of the mounts it SHOULD have
It shouldnt have solid mounts or poly. It should be designed properly so it wont want to jump out of the car with standard rubber mounts.
600lb/ft of torque is alot of twist when youre banging off a revlimiter
How come Mercedes, Ferrari, Lambo, BMW, etc can all harness a powerful V motor? Proper engineering. Even Chevy did a decent job on the C6.
im not defending dodge, tons of companies make smooth engines, its really not a big deal, if it bothers you, you shouldnt be driving the car… but you must also remember that alot of those car companies use electronic gear boxes, and most were transaxles as well so the shifter may or may not have been attatched directly to the transmission rather through a series of rods or cables, which would absorb some of the shock
Didn’t say he wouldn’t kick ass around the ring, just said he wouldn’t be able to remember EVERY shift point on 100+ corners, he wouldn’t need to, just arguing that point specifically.
hans stuck remembers what you at for breakfast last week, without even knowing you.
point taken
Nothing bothers me, we’re just discussing engine balance.
A lot of those companies do use electronic gear boxes now but their engines are still mounted properly in the car. When you hit fuel cut in a BMW M6 with the SMG trans, it’s smooth as silk. Ferrari’s V8 motors regardless of transmission dont move a fraction of an inch when bouncing them off redline. Seriously, we got a guy to bang it off redline in the garage at Watkins last year, there is NO vibration. It can be done, a lot of companies are too lazy to do it correctly.
alot depends on the rev limiters as well, my old VR6 has a very abrupt rev limiter, where as my stock limiter on my GTI was very smooth and un noticable, which i dont like at all, with my new software the limiter is much more pronounced. im sure dodge could have stepped its game up on it, but why bother, it does the job its intended to do, its a road legal race car. and im sure 99% of the people who buy it wont be bouncing off the limiter for seconds at a time
Yeah we refined europeans are spoiled by our soft limiters, but nothing sounds cooler than a badass fuel cut hard limiter :nod
:nod
yes, Yes and a thousand more times YES! It’s the single most important step of building a proper vehicle that american manufactureres skimp out on.
ever watch a carrera gt2 hit rev limit? nothing shakes, NOTHING. it just screams louder. them shits are rock solid. the motor may have great power, sure, but it shouldnt shake the hell outta everything like that. I agree with Jesse, they gotta re-engineer that mess.
The Viper is a brute, always has been, nothing is going to change that or it’s moving away from the essence of the car…thing’s a beast.
shrug it just needs to be refined.
