reed life

how many miles did you guys get from your reeds ,,mine are junk at 1100 miles 12-14psi and I see the cat guys are doubling up their reeds,,,, I wonder If we should try that or did you already????

might help, but i doubt it, the reason the cat reeds last so long is their reeds are lubed by an oil injection port at the reed cage where the polaris cage is completely dry. i usually get about 1000 to 1200 miles out of a set of reeds but have gotten as low as 600.

Symptoms of bad reeds

might help, but i doubt it, the reason the cat reeds last so long is their reeds are lubed by an oil injection port at the reed cage where the polaris cage is completely dry. i usually get about 1000 to 1200 miles out of a set of reeds but have gotten as low as 600.

So, how does one tell when the reeds are bad or going bad? Are there runability issues? Is there a way to inspect them without having to take things apart? What should one look for while inspecting? Just wanting to know what "symptoms" to look for, so i can replace them before the reeds come apart.

Also, i have heard of some guys using a little oil (100:1 or 1.3 oz to gal) in the tank..... in addition to the oil that the oil pump puts out, as a way to provide a bit of a cushion to the dry reeds. This also could be useful as a way to add a little more oil to the mix as the turbos use more fuel than a stock sled, with no added oil from the injector pump when on boost.

The reeds should last 600 - 1000 miles before you should replace as Preventive Maint.

Higher boost ... less miles.

Since the injectors on the Polaris are After the reeds (case and SDi cyl)... adding oil to the gas will not affect the reeds.

The reed tips split/chip and sometimes a whole petal can be lost (like in a "lean pop" situation).

Doubling up the reeds can help, but the more force required to open the reeds has a negative effect on low RPM throttle response when the turbo is not into boost or low boost.

1100 miles at 12- 14 lbs... I'd call that pretty darn good.

HOW the sled runs is pretty key in how long of life you get from your reeds.

High performance mods, especially boost like that, require a "race car" maintenance mentality.

Boysen makes a turbo reed, but I don't have enough time on a set to comment on them without speculation... The nice thing with the Boysen reeds is that the entire reed block/boot assy is aluminum (no more split boots).

as far as runability it will start acting funny, acting like it falls on its face but you can feather through it sometimes and not other times. i can personally comment on the boysen "turbo" reeds, we ran them on a 2010 TD8 last year for two rides, the boots kept blowing off and they would never stay seated, hopefully they made some changes for this year because it looks like a great concept but the fit and finish needs some work.

got 800 boosted miles on mine last winter. 8-13 lbs boost. Sled fell on its face. Severe bog and could not get any rpms. tough getting back to the truck

also here are the billet throttle body boots, any input on these?

Keep in mind charge temp plays a big roll in how long these reeds last without a intercooler they are subjected to high charge temps. On many M8's that were seeing broken reeds the mini intercooler played a big role in getting them to last twice as long without issues much better overall performance with the lower charge temps.

Jkinzer is right about the Boysen setup needs more time.

SOOOO back to the original question,, do you guys think doubling up on the stock reeds will help???? I think the stiffer reeds may yield better bottom end like the metal ones that were for sale awhile back befor they destroyed engines???
