just got a Vbox. any tips and suggestions on how to do 60-130s. never done these before.

i have k24 turbos, exhaust, tune, 5bar, 6speed manual.

gear (3-4 or just 4) ? when to start the run?

thx

 

Try from about 40-50mph and floor it in third. Repeat with second gear start and then try 4th gear and see what you come up with. Will all depend on when car hits full boost and how good your gearchanges are
Good luck.

 

I found that the least shifts, the better, but then again I am fairly mod'd and am near 7000' asl for what it's worth. Aslo be wary of altitude changes for getting the numbers published, what you think is a flat surface (<3% I believe) may not be.

 

What is your fuel shutoff on your ECU tune - this will dictate whether or not you will be able to do a single shift (3-4) run.

 

+1 on the shifts. You need to be pulling maximum boost before or while you hit 60. If you are just cruising at 59.9mph and stab the throttle your times will be poor.

There is many theories on doing these, I know my bro Tym has a bit of experience and tips, many of which he probably wouldn't let you in on, but that is just the name of the game.

 

For cars with similar mods to the OP, the best method in my experiance is to start at 2K rpm in third, floor it shift as quickly as possible, then ride fourth to the limiter. Depends on tire/wheel and ECU shutoff whether you can hit 130 in fourth. Many tunes raise shutoff to 7K in which you can easily hit 130 in fourth.
Some cars do better just running the whole thing in fourth (ie no shift). Others (mostly high hp cars with big turbos and raised redlines) do better with a two shift approach.
Just experiment some. Its interesting to see whats best for each car. Be sure to tell us how you do...

 

Subscribed....I also have a fresh PBox and cant find enough space to safely get to 130...also dont want to get arrested. I dont think I can make it to 130 in 4th....probably have to wait to get to Mid-Ohio

 

Just got my new Pbox too. Haven't had space to get to 130 yet, but a few 50-70's are logged. To the OP. Start in 3rd at 30-35mph, stomp on it, shift BEFORE redline (quickly) to 4th and stay in 4th until you hit the limiter. This is USUALLY the best method. However you do it, the idea is to be a full power (boost) when you crank past 60mph. Good Luck and keep us posted. If you can't get to 130 try some 0-60, 50-70, 70-90 just to get an idea and learn the software, if you don't know it already.

 

What's the big deal about offering a few tips to someone how best to run 60-130?

 

Maybe just the top secret brake boosting no one knows about? (that only gives me about a tenth or so)

 

I use this technique only at speeds over 100 mph

 

I guess the other thing that is obvious...program your VBOX correctly to read a 60-130. You don't want to be staring at your VBOX to make sure that you hit 130 when your eyes should be on the road, lol.

 

Most of the ones I have seen, including MY new one, seem to come pre-programmed for 60-130. I just had to stick my 50-70 in there.

 

agreed, hard to find those long - safe enough roads to run, at least everything here in South Florida is flat.

 

I know in the higher HP cars such as Sledge can do a 60-130 across about 750 feet, cars such as a stock TT take about twice that distance.

Still haven't found that 2.999% decline road yet either...
