I haven't even had my tires for 6 months and they are gone! What do I need to get so I can shoot in second instead of roasting them in first?

 

****, 1400 miles on my BFG drag radials and they are gone, stupid FWD.

 

Well you can either turn the system on in second, buy a bmn RPM activated nitrous switch w/ first gear lock out, Or place a Install a micro switch on the shifter to lock out first assuming you have a m6.

 

I'm gonna get a BMN box when I set up my NX kit. 4.10s = no traction in 1st I'm assuming. I'll be sending ~515/595 to the wheels with N2o, so I'm quite sure I will not hook in 1st, even with MT Radials.

 

Where can I get one?

 

most sponsers such as speed inc, FMS, daves nitrous outlet have rpm switches you can buy, just go to one of their websites or call them.
BTW, i thought those M/T radials were hookin really well in 1st and 2nd even on big shot cars?

 

Right now, I'm NA with heads/cam, and when I floor it in first, it hooks MOST of the time. But with a 100 shot on the way, I doubt that it will stick.

Maybe I'll try it before getting the BMN box.

 

PM'd you.

 

u ridin on the M/Ts now?
Mine dead hooked on motor w/ the TA but no nitrous attempts yet cuz its still got a surgin prob & my bands in the tranny burnt up for lack of putting on the trans cooler

 

Yup. I love the MT's. Right now with the weather warm and the roads hot, she sticks.

But in December, WOT in 1st got me a little squirrely until I let out more psi (28 to 22) from the tires.

 

361/412 on M/T drag radials with 18psi ad a good burnout = a dead hooking 1.63 60-ft here

 

Here's my first gear lock-out micro switch. It's a three way terminal type (open/closed your choice). I run it in conjuction with a WOT ms but wired opposite of wot sw. That way when full throttle the system won't engage until pulling out of first. You can set this up with existing WS. I am using it on my 2nd stage only, and running dual ws and single wot sw for both stages (wired a little diff than explained).

 

Oh, on the track, yes, MT's hook hard with 19 psi for me after a good roasting. But N2o on the street with 4.10 in 1st will produce a different scenario I'm sure...
