Im talking about off the line acceleration. A vehicle with a clutch will allow you to feather the RPM much higher to build boost quicker.
Actually, you hold the brake, rev the engine against the brake, and you launch on boost. Pretty simple. And then you maintain boost through each shift.
Sounds like you have very little experience with cars in general.
I think he meant to keep the engine RPM high for the BOOST at a launch.
Locking/holding the brake can work in some vehicles but not in all applications.
Knew one VW dragster that had 20lbs of BOOST on the line. He had an Auto trans that would screech the tires when it hit 2nd gear. We were competitors but my engine had Carbs with NOS and a 4 speed trans.
YOu can still do that trick on a modern car, you just have to hold teh brake, quickly bring up the revs in 1st and let off the brake when you get up to boost. Should take less time than the computer contolled nanny lets you have.
Too broad a question. Depends on how heavy the car is, how it is geared, how the computer handles boost and timing.
The car with the better power to weight ratio that delivers more torque to the ground faster is going to win no matter what engine it has.
^ I had an MG Midget with a Toyota 4AG 20v swap. 160hp inline 4 with a peak torque of 119 ft/lb... not exactly amazing... but the car only weighed maybe 1500lbs. That thing launched like something you'd normally see on an aircraft carrier
As far as 2.0T's go, when I test drove a VW GTI 2.0T with DSG, there was almost no perceptible turbo lag, and it was still quite good with a manual... a vast improvement over the older 1.8T's or my '86 Saab 900's 2.0T.
Yeh, Saabs with manuals seem especially laggy. Pulling away from a standstill, I could read a book waiting for the turbo in my 900 to kick in. But out on the highway it would respond almost instantly to requests for passing power, and without needing to downshift. Held full boost to redline too. That car was obviously made for bombing down highways -- not a particularly good city runabout.

Yeah, as long as you kept it in the right spot in the power band, you had a good amount of power on tap. It worked well for winding New England backroads, too, as long as you knew your shift points I miss that car, for all its maddening - and expensive - quirks.
