Anyone run a weiand 8-71 on their boats?

[BOOGEYMAN]

I have a 502 that will be a 540 here shortly and was going to buy the weiand 8-71 kit from jegs or summit and noticed they make a marine application. The difference they say is that the marine blower has thick walled casting rotors that are made of a single solid piece of 4340 to prevent "rotor growth". Anyone have any experience with this or any input?
I was guessing the rotors may be different because of the heat on long pulls but wasnt sure wich kit to purchase, just wondering if it is really worth the extra money for the marine kit or if they are just trying to make it sound better than it really is?
here is a link to it. http://store.summitracing.com/partdetail.asp?autofilter=1&part=WND%2D7189P&N=700+115&autoview=sku
Thanks for any input someone may have!

remember one thing. weind is the company that invented the three bolt crank pulley adaptor and the 14-71 mounted BACKWARDS so that there is no distributer clearance proplems. Both of which are total crap. go with blower guys. blower shop littlefield, mooneyham. let weiand make valve covers

Why yes, I'm running one.
The polishing is chitty, the casting on manifold and blower has lots o nice pits, and the three bolt pully deal SUCKS. A reputable shop will have closer tolerances too.
Other than that well it's just fine.

Thanks for the link sangster. I looked at their site and see an 8-71 bbc kit and then an 8-71 bbc cheny marine kit as well. Lokks like they teflon stip the rotors in the marine kit but not the other?? Anyone know why?

Thanks for the info!! A few buddies run them on ther bbc street cars but I wasnt sure on boat engines. Do you run the street kit or the marine kit? What boost level with what set up? Thanks for the info again!

Street kit bought it a few years ago, it makes about 12#'s at 13% over.

I have a 502 with a 871 weiand running around 5 pounds of boost. 140 hours with no problems on the blower, broken outdrives are a differant issue. My rotors do not have the teflon strips.

i ran a weiand 8-71 street blower on my 502. no problems with it at all except for the three bolt crank pulley shearing the bolts off. bought a new 6 bolt lower pulley from BDS and never had a problem after that. in low boost applications the weiand blower works fine. no need for the teflon strips.

[BOOGEYMAN]

Thanks guys!!!! I saw some pics and spec's of Schiada76's set up and it is killer with 6 years on the weiand street kit and no problems eithor. I think I will go this route and keep everyone posted, thanks again!

Travis,
I've been running one for about 6yrs. now..only failures I have seen are the rear bearings going out..I drilled the rear bearing cover plate and installed 2 grease zerks...to allow me to give them a dab of grease before I run ...still change out the bearings every 2 yrs. though just to be safe;)

[BOOGEYMAN]

thanks for the info, thats a slick set up you did with the zerks!!! Have any engine pics you care to share??

Gotta watch out for those flying towels. :crossx:

[cyclone]

Gotta watch out for those flying towels. :crossx:
the towel only stopped the belt, not the blower. he didnt ask if the belts were any good. lol:D

[BOOGEYMAN]

If the belt stops how does the blower keep spinning........:) LOL.

Mike can tell you all about that.......he's had plenty of experience in that department.:devil:

[cyclone]

If the rotors aren't stripped with teflon and the clearances are loose, the blower will keep spinning slowly because the engine is still running, still trying to draw air into the cylinders. The motor will keep running without the belt but it'll run fat as hell and you'll be fowling plugs. its kinda fun to watch. I broke my belt on a friday at the river, had no spare and drove it the rest of the weekend. just had to change the plugs at the end of every day. lol
