:lmfao: thats a kick ass gauge!

 

20" et drags and a 6000 rpm vtec launch on an ACT HDSS clutch. I also pulled 2.1 60 foots on the 175/65/14 stock firestones/steelies deflated to about 20 psi with very careful clutch/gas feathering, i can drive.

 

:shocked: wow......you CAN drive.

 

vtec launch? how is that done?

 

launches while vtec is engaged im guessing?????

 

Vtec does not engage while you're speed is under something like 20 mph, so unless he modded his ECU that wouldn't be possible.

 

Well you just hold your launch rpm higher, when i launch on slicks i launch around 6500 rpms cause the tires are so sticky if you launch lower you'll bog. The feeling of pulling a 1.8 out of the hole in a fwd non LSD civic is amazing, it just shoots you forward and before you realize what's going on you look up and you're going 35mph at the end of 1st gear ready to hit 2nd.

For street tires i generally launch around 4500 rpms and slip the clutch out. I've posted a ton of times on my street tire launch technique but basically hold the gas steady at whatever rpm you need when the 2nd yellow light turns you start to let the clutch up about 30%.

At this point you give it about half gas and feel the clutch engage the car, when you feel the tires start to spin up a little and the car gets traction give it more gas and let up on the clutch a bit more. It's just a delicate balance between clutch/gas until your car hooks up then you basically just mash the gas WOT. It's kind of hard to teach you just have to go and get a feel for it. Also for you guys launching on street tires it's important to deflate your tires to around 20-23 psi to give you a wider contact patch at the drag strip just don't forget to reinflate them when you leave. It is NOT NECESSARY to do a long smokey burnout on street tires or to drive through the water box. I always go around the waterbox on street tires then do a very short 3-5 second burnout just to clean the tires off from the gravel etc.

 

As far as i know VTEC isn't based on speed it's based on RPM of the engine although you could be right. My main point was just that on slicks or drag radials you'll have to launch the car harder cause you have a lot more grip off the line so i launch around 6000 rpms (where vtec would engage).

For all you guys that need a little extra help get yourself some good drag radials or small slicks it makes a world of difference. On average i pulled 2.1-2.2 on 15" street tires in the civic although my M3 is capable of 1.9's on street tires

 

I'm almost positive VTEC is based on speed. One of the features of uberdata is allowing you to remove this limitation. Heck, 20 mph is gone in no time when you're running huge slicks like that.

 

You could be right, i haven't done much research on vtec/altering it because honda did a very good job out of the box tuning vtec crossover etc so i didn't feel like i wanted to screw with it for my application. Also 20" slicks are VERY small, they look like a very bald street tire with a very high tire profile maybe like a 205/65/13. Hardly anyone at the track noticed i was on slicks but they were all like when they saw me rip a WRX out of the hole that was running consistent 2.0's on street tires.
