Straight cut gearbox on a road car? Good idea or bad?

About as good an idea as a rollcage and stripping the interior.

>explaining shit to plebs

Your a fucking tard. Gears are specifically made to be slanted to allow the gears to be quieter during travel. You'll hear nothing but a very pissed off transmission the entire time your driving. I just got my car a a few weeks ago and I already know this. The fuck is your problem

Why aren't herringbone-gear gearboxes a thing yet? Surely by now we have the manufacturing technology to produce them at a feasible cost?

Straight cut gears handle more power before grenading. The only reason to ever go straight cut is because you need them, and then they are a necessity

Less weight and stiffer bruh. I might do that to my sc400 and then it will have the chassis from a supra and weigh the same. With supra suspension and a supra gearbox connected to a lexus v8. Grorious.

>Surely by now we have the manufacturing technology to produce them at a feasible cost?
You obviously don't know how gears are made.

The sc400 is a glorified Sora, not Supra

Same chassis and suspension. It can be very supraesque with work. For instance w58 swap, supra brakes, supra coil overs. The sc is a soarer with different badges

Sure if you're deaf it is an awesome idea

The whole advantage of straight cut gears is they don't produce any axial loads. Which means they can take more power/torque reliably.

So unless your pushing lots power to necessitate them, they're pointless on a street car. Not to mention transmission jobs for those types of upgrades aren't cheap.

>Foxbody there with straight cut gears
>Gear whine is atrocious and each shift sounds like a gunshot

Would not dd/10

bromaro tripfaggot

would shot on sight/10

well some of them have straight cut stock, just on the reverse tho

the sound isn't really my cup of tea but if you're into that shit then go ahead if price and carefulan obscure shifting technique isn't a problem

Do you want your commute to sound like JAV?

>not having a straight cut transmission, straight cut differential, gear driven cams, squealing race brake pads, hard sidewall summer tires, solid motor and transmission mounts, stripped out interior and sound proofing and the quietest exhaust you can manage

Do you even race car/pussy deterrent? Just wear some hearing protection you idiots.

Oh my god kill me. It sounds like a supercharger but we all know it's not.

good if you want the meme whine

id want a sequential gear box if i was goong through all that work

Bad idea. TERRIBLE idea.
At least both of those have actual advantages.
>Straight cut gears handle more power before grenading.
No, they don't. In fact they both handle similar amounts of torque, but helical gears can do so at much higher speeds.

The only advantages of spur gears over helical gears are that they are cheaper and easier to fabricate, and are easier to assemble in reconfigurable gearboxes (both of which influences racing teams' decision to use them), and that they don't produce axial thrust.

>don't produce any axial loads.
If you've got unlimited money, there's double helical cut gears.

>that fucking gear noise

fugg, that'd get old pretty quick

WHAT!?!

good idea
stop being a pussy and do it

pussy

kek

>not having a straight piped straight six on that god machine

>don't produce axial thrust.
What's the benefit of this?
Also, I thought that the advantage was ability to change gears quicker.

>putting a full rollcage on a street car.

You know in case of accident your brain will splatter all around the interior right?

Almost all motorcycles use straight-cut gears because of this.
It mens you can use a much weaker and hence lighter transmission case.
Also, nobody cares about noise on a bike.

>Also, I thought that the advantage was ability to change gears quicker.
Considering the gears themselves are constantly meshed regardless of cut, it makes no difference what so ever.
>No, they don't. In fact they both handle similar amounts of torque
Have to pull you up on that one. Straight cut gears have more surface area engaged at any one time, and can transmit more torque reliably as a result.
>but helical gears can do so at much higher speeds
This is spot on. As helical gears engage gently in a swept motion across the tooth. At higher RPM this is more mechanically forgiving, but it's also this reason (less surface area contact) straight cuts handle more torque.
The rest of your statement is spot on.

Also worth noting, straight cut gears are prone to accelerated wear when compared to helicals, as the friction involved in meshing is much higher.

holy fuck, it's modified to be as whiny as possible right?

not if it's not near you're head.

You sound like an idiot. Stop typing like that.

The solution is right there in the picture, nigger.

If you manage to kill PPG helical cut gears, you're a shithouse driver.

>playing Gran Turismo 6
>upgrade first car
>now has too much power for the stock transmission
>dread upgrading the transmission due to the straight-cut gear sound
>upgrade anyway cuz muh power
>transmission is now louder than the engine

kill me

>doesn't know that the compounds best for racing also squeal like a motherfucker and are generally unsuitable for DDing for this reason
Spotted the 12yo bus rider

>straight piped straight six
>not straight piped straight five turbo

Does anybody make a transmission with helical top gear and straight cut lower gears? Seems like it would satisfy the small market that wants a track ready DD.

How do you shift that?

What are you talking about?

>>Not driving around in a straight piped turbodiesel called Ric Flair

Its a typical straight cut sound. Not an extra noise mod or anything like that

with strait cut loosing the tooth is a big deal the entire thing just pops off and can wreck everything
where as helical tooth most often has little bits fall of it first
and even when one tooth falls of its not a problem
the last few gears on that sound crazy

>wanting your shitbox to sound like a screaming autistic child on ritalin
no thanks

its great when you want your passenger to shut up
and makes their ears bleed

that's what the dogs and synchrony are for

Whatever, I'm a dead man in case of an accident anyway. May as well go out with a bang.
