MSD Launch Master WOW

[1000 Bound]

Just installed the launch master stutter box. Sled is an Apex with the MCX rear mount at 12 psi. Complete trail sled set up for the asphalt. Sled is to have 260 claimed HP. Sled was terrible launching with turbo lag.

I now have the stutter set at 4900rpm and it builds 4-5 PSI boost.
Can anyone tell me an approx hp the sled would have had at 5000rpm with zero boost and now with 4-5 psi boost at 5000?
The flames coming out of the exhaust pipe are incredible.

Also need to know th adownfall to the stutter and the dangers to the motor.
Thanks

well had the msd out to test this weekend and it is absolutley the best mod for the buck for drag racing. An honest 3.5 tenths reduction on the asphalt

Is it that would work great on hard pack snow ?

Sled was running with me on it at 250lbs with gear at 6.5s 1/8 and now 6.22. All in hte 60ft. went from 1.62s to 1.23 60fts. With a driver 50lbs lighter the sled was running 6.3 prior so we hope to see it in the 5s in the 1/8. With the lighter driver it ran 9.91 at 143 mph in the 1/4 prior to the msd

How was the install?
I'd like that for the ice. Rear Bender w/ 2560r
Unbelieveable how hard it hits on ice!

it's simply just plug and play. there's room by the hi/lo light switch for the button. get one from radio shack. I have mine set to 5300 rpm stutter. to much for snow. I use mine for grass drags with a speed track running chisels. Just trying to keep the front end down now. Wish i would of extended the rails. Just going to run the illinois races this year, moneys tight.

On an RX1 I would be surprised if it took any more than 5 minutes.

The Apex takes longer cause you need your 5 year son to reach in with his hands to connect the harness.

I don't think it works on RX1, RX1 have CDI ignition, Apex have ?

The launch mater will not work with 03 RX-1 CDI ignition.
This was confirmmed with msd tech support.

It will only work with coil on plug applications. yes the apex is harder, even more when you have a mid-mount turbo (cpr).

The RX-1 has coil on plugs! Can it be used on the RXs? If not, why not?

How does the msd know when to actually launch and stop the studder? Is it with the break?
