Default Manual brake boosting

I have a stupid stupid question, but would it be a good idea to brake boost in a manual? I'm just afraid that the clutch would slip and burn up. Thanks

If you're rolling it's very possible, and if your clutch isn't junk it should work great. If your clutch is junk you will know in a hurry.
If you mean off the line you're probably going to need 3 legs

Is your setup really that laggy in the first place ?

op nothing wrong with brake boost(as long as your clutch is good), I do that all the time on roll. I learned this from my supra days and is actually really usefull against s/c cars.

ever look at a dyno? depending on how much boost/hp his running he could easily double his n/a power on boost.

even with a match setup leaving a roll on boost will leave faster. meaning you go when you let go.

would you rather take off trying to build boost or on boost?

no you dont(not like you can anyways). auto is easy of course but even manual can do a bit of brake boost off a line. its called ebrake.
takes a bit of practice but youll leave faster for sure.
just be carefull not to slip the clutch too much and burn it lol

You want to brake boost on a dyno ? how random.

And that depends how bad your gearing is to leave you off boost, depends on the setup, depends how much traction you have, etc etc.

And of course more pertinent to the OP...whether his clutch can handle it, or whether he even has enough power to overcome the clutch...

Details in general are very sparse.

I don't think his clutch is going to be the problem. For me, it has always been the rear brakes. I could never brake boost on stock rear 4th gen brakes, but on the other hand, in a C6 vette, I could brake boost. Those brakes are awesome.

no not at dyno i was just saying the power difference between the time it builds boost vs on boost can be huge(which a turbo dyno shows pretty clear) im sure you know that already i was just saying that to make a point.


i completely agree that its setup dependent. but you cant ignore that fact that leaving with boost is going to be way faster than not brake boosting.

not to mention it seems like most setup arent exactly optimum.

Not really, as long as you are 3,000+ it lights off pretty quick, but still nitrous/supercharged cars have the advantage off the start during rolls, and I just need to know if it is safe to do with a stick
