spooling turb while reving in a 1G

[quick_shifter]

i was wondering if there was anyway to make my turbo spool up while reving, and whats keeping it from spooling?

juss rev the shit out of it, it shoudl spool.

obviously not a good idea, but you asked

If you get a stutterbox for your car a 16g will be able to build about 5psi. This can be done w/ an ignition system, a computer chip, or dsmlink. W/ DSM link and antilag you can build 15psi of boost on a large turbo

I asked this before and ppl told me you can build boost by revving it quikly up to like 6000rpm. I wanted to know so i could do stand-still blow-offs. Many ppl also told me this is bad for the engine because there is no load on the engine and it can break stuff. I didnt quite understand but lots of ppl told me it was bad.

try it if u want

Well, again.

Look at what "boost" is. It's more air being pumped into the engine than the cylinders can admit. What keeps them from letting it in is load: usually, the mass of the car as held up by the tires' contact patch. Until there's a catastrophe (large [driveline] or small [clutch slip]), you're pushing against that patch with the expanding gasses of the burning fuel/air charge until the tires break loose. The turbo will only put out so many psi until the molecules of air in the intake will pile up so close together, and the turbo can't push against them any harder. If you don't have the driveline connected to anything, the pistons can just run faster and faster under more and more power until something goes pop. Trying to wedge more air into the intake than the pistons can hold back (BOOST) on a free-revving motor is very hard on all the engine components, as well as being hard to do. All you have resisting it is the inertia of the flywheel and other revolving parts (crank, cams, drive belts, water pump, alternator, AC clutch, rods, piston mass and ring friction, oil pump) and those seventy pounds of load go away once they're up to speed.

If you want that glorious blow-off sound in neutral, it's better to get an electronic blow-off simulator. Blow-off isn't a goal, it's just a by-product. It has the approximate entertainment value as a baby derives from shitting its diaper.

It's not really that bad for your engine, it's more bad for engine components, including your t-belt, your harmonic balancer, and your belt-driven accessories that weren't built for that type of abuse. You're basically applying all of the engine's force to those components.

As an example, when in gear, the t-belt usually brings the cams up to speed smoothly as you go through the gear. When you rev in neutral, it has to get the cams up to 6K RPM in a split second. The cams' inertia makes them want to avoid this change in velocity, so you shock the t-belt. Same with the balance shafts and the balance shaft belt, to an even greater extent. Same for accessories like your P/S pump and your water pump, you're accelerating them to high RPM in a split second. The bearings in units have to absorb the shock.

You'll probably be OK if you just don't do it all the time. Otherwise, be ready to replace your accessory units.

As I post this, I look down and realize Defiant pretty much summed it up, but maybe this will help some.

Someone has stumbled upon what a ricer truely is.

Excellent work.

Check that out.

why don't 1G's do stand still blow offs and the 2Gs and just about every other turbo car does. for instance a buick grand national when they rev they blow off and you can hear the tubo fluttering.

why can this guy do it!?!

Hes only revving a little.

sorry to dig up an old thread, but i was messing with the throttle and then my 1gen bov went off. Is it not suppose to go off? I read this other thread that if a screw is loose then it would let out a sound but if it is tight then it shouldn't make any sounds. Is there a screw to tighten the 1gen bov or no? Also Is this Normal?

Its okay if it makes a sound.
there is no way to adjust it also.
Mine would make sound at 0 or even a little under 0 in the negative hg

At least get a good one if you are going grave digging.
