Dragy va vbox


Recommended Posts

All,

 

just bought a dragy and i have to say it is brilliant .

it connects to phone and does gps refresh every .100 sec and quite accurate

 

running on low boost with falken tyre i get a 0-60 of 4.6 sec but if I practice more I think i can get it down to 4 as it doesn’tgrip

 

do you guys shift into 2nd as soon as it is rolling to get fast 0-60 ? If i leave in first then 0-60 is around 5.5 

 

i stick it to 2nd as soon as I have wheel spin and it bounces from red line and then get mid 4

 

on high boost which I haven’t tried (500bhp) i reckon it will be 3.8 if i can get power down

 

on low boost it is 430 bhp

"G4" doesn't give us enough info, there are G4 Fury, G4 Xtreme, G4 Thunder... etc

I'm trying to work out what is your base spring pressure and max boost pressure and if your ECU has traction control functionality. 

If you turn boost control off, how much boost does your turbo make?

How do you guys get grip when accelerating?

 

shift to gear up at expense of less power initially but grip?

Your computer can set lower boost levels in the lower gears.

Different suspension set ups.

Drag friendly tyres.

You could lower your base spring pressure to say, 0.5 bar and then use a 4 port mac valve and run a very progressive boost by gear. 

You could setup your traction control. You haven't said why it doesn't work, I'm guessing you need a non-powered wheel speed sensor. 

Stickier tyres as mentioned above. 

Actually I think this has all been said before, this thread and your recent tyre thread.

You do know that you don't have to mat the throttle, right?

Yep and that is not with flooring it

 

0-60 is around 5 sec at best 

got pair of michellen sport 4s so will report back if it got any lower

Different alloys at front that is all

Just larger diameter rear rims that’s all, like that’s normal.......

So tyre made a massive difference 

 

pilot 4s rear 275

 

front is pilot 4 which doesn’t really matter for acceleration. 0-60 went from 5.3 to 4.8 a wopping 0.5 sec !!!!

 

it sticks like a glue, i can’t even spin wheel on first or hardly it does. It used to spin like hell on first and second on shitty falken

Dragy is awesome! We use one in my car at roll racing to see if the changes are working. Fastest 100-200 is currently 4.11s, with the old turbo. New one I've done a 4.25 on 30psi in the middle of summer. Should go mid 3s now we've got it turned up if we can get it to hook up.
