Snow Performance Boost Cooler, rear disc questions

[paddler]

Does anyone have any experience with the Snow Performance Boost Cooler water / methanol injection system? I'm considering this system: http://www.snowperformance.net/product.php?pk=65 to keep EGTs down. I've got plenty of power for me from my Banks system, but I'm real close to the listed EGT limits on slow curvy climbs at moderate throttle and no to low boost. Downshifting usually help EGTs a bit, even though I've got plenty of torque and adequate RPMs in a higher gear. EGTs are much better on main highways, likely because I can keep speed, boost, and thus airflow up. On rear disc conversion, it looks like most of the folks who rave about their brakes are using non-e-brake front calipers, which should provide more stopping power than rear e-brake calipers. I'm interested in folks experience with braking improvements using rear e-brake calipers. Thanks for any insight.

I didn't know the non-e-brake calipers provided more stopping power? I have the e-brake calipers and like them a lot. With my heavy loads on a hill I need the e-brakes but I also would like more stopping power. Considered snow but never went through with it.

Thanks for any insight.

Those two calipers should provide the same stopping power as dimensionally they are the same. Just the rear calipers have parking brakes design as well.

Most of the testimonials for rear disc conversion seem to be about great stopping power using front calipers (from a Chevy 1/2 ton?) From what I've seen, the front calipers have larger total piston area than either variety of rear calipers, and larger piston area should translate to more braking force.

For braking improvement, I think the question is does using rear calipers with a disc conversion provide a notable stopping power improvement over stock drums. Since I need a parking brake and don't want to mess with driveshaft brakes or auxiliary calipers, my options are rear calipers with parking brake or staying stock.

After some more thinking, I'm leaning towards not doing anything until my rear drums need servicing, then doing a disc conversion.

theres guys over at PSN that swear by the water meth kit, 30% meth and 70 water seems to be key over there, they have reported amazing results with the kit and its very easy to install, i will eventually be doing that kit later on down the road.

this is pretty good evidence that it works

When doing the rear disc brake conversion do the disc brake cylinders have a larger fluid capacity than that of the shoe style cylinders?

In other words does the stock OBS master cylinder have enough capacity to adequately supply all of the wheel cylinders with pressure/fluid?

I run the Snow Performance Boost Cooler and love it. I was pretty skeptical at first but the huge drop in EGT's won me over. I would suggest just running 100% water if you are just looking for EGT numbers. There is mixed feelings on the meth usage. IMO, small percentages are ok, but I would rather go with what Jody at DP told me. He advises just running straight water so that the meth doesn't affect the timing.

Yes, the master cylinder in our trucks does work fine. If you wanted to go bigger, our year of Super Duty does have bigger pistons. I also have a 88' F350 DRW with rear disc on it also and put the Super Duty master cylinder on it, with a hydroboost. My 97' F350 SRW with rear disc, with vacuum booster and stock master cylinder works just as well.

I've considered snow's performance for a few years now but I can never get a honest answer of how much water you have to carry. Would a 55 gallon drum be enough?

[rideracelivemx7]

holy crap lol, the kit only comes with a small 3 gallon or so, 55 gallon drum, your in the game to drop egts, not look like a hick haha

Unless your running a 80,000 over the road truck you won't need that much. I run the Snow MPG MAXX Stage 3 and it comes with a 7 gallon. Even running it constantly it doesn't run out in between fill ups when towing. Great thing about water is its free

[oldbird1965]

Clay, I'll have to go back to snow's website but what is the mpg maxx and how does it compare to just the stage 3? The way we waste water, hopefully it will stay free!

Basically the MPG MAX comes with a 7 gallon reservior and the controller is programmed for 2 modes, MPG for when you empty and TOW when you hauling. This way you get better mileage and lower egts.
