Default 3-stage 300 shot and MS4

I want to run my MS4 in my new motor setup, but I am going to run a 3 stage 300 shot. Its going to start out with a 75 shot out of the hole(I launch at 4000), then a 100 shot along with the 75 shot in second gear. the 75 shot will engage at 3700 then the 100 shot will come on at 4300 then the 125 shot will come on at 4700. I then will run the powerband to 6600 and hit 3rd and repeat the process. I know 300 is a large amount but, I've seen it done with these cams. If its multi-staged, and in higher rpm band when its engaged...Then wouldn't I be able to use my Magic stick 4?

Sounds complicated and expensive....A single stage with an RPM based progressive would be much cheaper.

Both the FJO and the new NOS Launcher will support RPM ramping and will let you program a curve that can add the power where you want it.

I think it would be more expensive than worth wild on a car only spraying 300 hp.

I would go single stage progressive and since you're having your motor built I would have a cam specified to your exact application.

Get something with at least a 114 and up lobe and I would try to get something with at least 8 or more degrees of duration on the exhaust side.

I dont want progressive. Plus with stages i can leave all but like one big one off. I dont plan to hit all 300 with out a tune ( two different tunes downloaded onto diablo programmer) and race gas in the tank.

I just love my MS4 on motor, and I had a 150 shot on it for about 2 months and spun a rod bearing. I was hoping I could get away with it but I guess not. I have found that the supercharger cams seem to be almost the same as dedicated nitrous cams. I was looking at the blower grinds at speed inc. http://www.ls1speed.com/catagory.cfm...in%20/%20Heads
They seem to be right around the specs im looking for. What do y'all think?

Just go with a direct port and be done

MS4 with 300 shot here. I use a fjo mini controller to bring it on smoother but either way its badass.

Good for you. I understand exactly what/why your doing what your doing. The progressive camp will never get it. But likely they will get it when one of their noids fail, lol. Progressives have been out for many, many years, and there is a reason the vast majority of serious racers don't use them.
Some of these guys use the progressive for traction, and that's a whole different ball game compared to going big and spreading the load out, and the easy option to chose what stages to use. Hell, for traction problems a digi timer works as good and is much cheaper.

exactly! Thats another reason i wanted it set up like this is so that I can catch all the traction in each gear before the big hits start engaging. I have spent alot of time figuring out how to do it right, and I think this is the most direct way of injecting 300 hp worth of spray without the damaging effects of controllers and other stuff. I am however going to use an msd window switch on this setup.

the classes I run in only allow 1 stage....so that is one of the reasons I am running a progressive.

In the other thread you stated you were running it for traction, but both are valid if ya like progressers.

yeah to each their own. Im not gonna dis anyone's setup, I just know in my mind what I want to do as far as my setup i was just wandering if an ms4 will work with up 300hp worth of spray. I know a few people doing it and ive talked to a few guys doing it. As long as i hit it above 3500 then i should be fine.

it is the same thing.

I am limited to a single stage, I want to run a 300 shot....I can't hit it all at one time so I use the progressive to maintain traction.

Put some bigger slicks on, lol. I guess that's why they limit you to one stage, but still it seems you could run as big of hit with a progressive as you could with a multi stge, so why the limit? You can do the exact same thing with either, spreading the hit out, makes no sense really?

The ms4 will work with any nitrous setup, now will you gain as much on the nitrous as running a specifically ground nitrous cam.. NO.

that being said. What would I really lose going with the MS4 over a dedicated nitrous cam?
