Re: busted inner cooler insert

Melinda,

You might want to check with Whipple Industries. I believe they make a replacement core that will fit the Lee cooler.

Re: Need help finding Parts for 2001 575 Weiand SuperCharger

Geronimo,

Steve is right that the Holley 256 blower is basically the same as the merc 575 blower. The only difference is the case and end plates are not hard anodized and on the merc blower, one...

Re: intercooler cores for blower shop intercoolers

Ratman,

We only make an aluminum core for our intercooler. However, K.E. / Hardin marine makes a cooper-nickle replacement core that fits our housing. We have found the same thing that the...

Re: B&M 172 Blower?

Dion,

Just looked at your blower and you have a B&M 174, so the Weiand blower will not work for you. Unfortunately that style of blower has been discontinued by Holley and there are no...

Re: 525SC / Weiand Blower failure question

This is actually a common problem on the Weiand and B&M blowers. Here are a couple of reasons why it happens.

1- Non-heat treated shaft and coupler

2- Low on oil. Most blowers we see have...

Re: B&M 172 Blower?

The B&M was a 174 blower and the Weiand is a 177 blower. Weiand made the 177 blower that was used on the merc 525 package that is painted black. The polished Weiand 177 blower is the same blower...

Re: Blower problems

Your best bet is to try and find a complete used blower. We have gone through about all our used parts for the B&M 250 blowers. I believe we have a blower housing, but only one or two mis matched...

Re: 575 Blower Bearing Problems

All of the 575 blowers use the Weiand 256 case. If the front gear cover has a W on the front then it is the original Weiand Style. The new style uses the same case but the B&M style bearing plates...

Re: 575 Blower Bearing Problems

The 575 blowers went from the Weiand style to the new Holley style. They still use the same single row bearing in the front but went to a sealed single row bearing in the rear. The sealed rear...

Re: 575 Blower Bearing Problems

zahndok,

The rotor diameter and lenght are the same in all three blowers. Well acually the weiand rotor is around .025" smaller then the B&M. The 256 is just the name/number that Weiand gave...

Re: 575 Blower Bearing Problems

Steve,

The Weiand mounting flang (8 bolts on the side of the case) vs. the B&M bolting through the bearing plates is much stronger and does not allow the blower to flex as much. This was the good...

Re: 575 Blower Bearing Problems

Plums,

Our blower is not really going to make much of a power difference over the stock Merc 575. We have had some of our customers report about .5 to 1 pound of boost increase at the same drive...

Re: 575 Blower Bearing Problems

Weiand used a standard 80-90 wt gear oil.

Any good quality gear oil with a gl-5 rating will work.

We however now only use Red Line Heavy Shock Proof oil in the Merc 525 and 575 blowers.

Re: 575 Blower Bearing Problems

Dano,

Which blower are you refering to?

If it is a 420 blower we move them into an 8-71 blower. This does require a manifold and drive kit as well. If it was an 8mm drive you can use your...

Re: 575 Blower Bearing Problems

An oil drain plug would be helpful especially if you want to change the oil while the supercharger is on the motor. You probably wont get all the oil out, but you can get the majority...

Re: 575 Blower Bearing Problems

Tim,

There really is not a good answer on how offen a blower needs to be rebuilt. We rebuild a lot of B&M blowers every year. Most of them have between 200-500 hrs. Usually with this aomount of...

Re: 575 Blower Bearing Problems

Tim,

The up-grade that we do on the B&M blowers is the billet bearing retainers. The stock retainer was a stamped steel retainer that was weak and tends to crack around the bolt hole. They also...

Re: 575 Blower Bearing Problems

It is hard to put the rear plate back on because it does try to hydraulic the seal. We are now drilling the rear bearing plate and installing 1/8" pipe plugs to allow the air out after the...

Re: BOOST,VOLUME and BROKEN ENGINES

What Mcollinstn said is correct, at equal boost the 8-71 will have a cooler more dense air charge that will make more HP. What you have to remember is that the 177 blower has to spin over twice as...

Like I said earlier, the 113% ratio will give you 10-11 psi according to the Weiand chart. You have to remember that this is a generic chart based on a stock engine config. The better the heads and...
