2nd gear launch
 

Hey, Right now Im sitting at about 600whp
Im tuned with Haltech to run about 400whp in gears 1-2
I find that first gear is soooo short, its crazy.

I have DSS 5.9 Axels, Stock 3.5 Diff and VLSD.
A 6 puck Ceramic clutch.
Mickey Thompson ET Street II

I do my burnouts in 2nd gear.

Can I launch in 2nd? if so, if anything would "Give" what would it be first?
I ask because I have an extra Twin Disk Clutch, an Extra 3.3 LSD Diff sitting around. So if its one of those 2 things then Id be happy with risking that.

Im asking because Im sad Im running 13.5@118mph lol. with 2.7 60"

Did you let off the throttle on that run? The trap seems low for that kind of power.

No, but I am a VERY slow Shifter...

I blew up my Audi S4 3 years ago trying to speed shift.... lets just say that engine could rev to 20,000rpm haha went from 4th to 3rd.

Also the track I went to is the SHITTIEST track in existance. There is tonnes of bumps in the lanes, so when I went over a bump, and unweighted the wheels, they would spin out in 3-4-5

Ok.

Soooooo
2nd gear launches killed my 600wtq rated Clutch in 3 runs haha.
Now it Slips under boost.
Thankfully Bully Clutch is local and gives me great deals so they will rebuild my clutch for $100

But the twin disk is going in haha.

I find shifting fast from 1-2, and a little slower from 2-3 so the car doesn't bog and everything after that is a quick shift. And since you killed the clutch you found the weak spot :-)

haha Ill try that, But Im not a fast shifter haha.

What clutch are you running? and tell me how it is on street and track?

Trust me with turbos gt30xx and up just shift clean and led the boost take care of the rest.
I'm using an exedy twin disk setup. Might need a triple or quad but I won't know until later this week after I get retuned.

Here is a 6 puck with less then 8000km on it.
its rated for 600wtq, I was making 546wtq.

Thankfully, I can get it rebuilt locally same day, and have clamp load increased for less then $150.

2.7 60'?

Good golly that's awful. Most people are getting 2.0 stock.

So what's your issue? Spinning or bogging or lag?

If it's spinning, try launching at a lower rpm.

Bog, higher rpm

Lag, higher rpm

I'd think ET street would be MORE than enough. There are people running 9 second 1/4 miles at 140+ mph on those tires.

And yes, when you launch hard and get traction, something is going to break.

It was a suspension problem, I was running very stiff JIC Magic FLTA2's

Best time was 11.6@129 with a 2.5 60ft
