Want to drive a fuel pump off your BOP belt drive? Step in here.
 

For blown or unblown BOP belt drive users looking to cam drive a MFI fuel pump you NOW can!

The prototype on my current blown alcohol IA2 engine. Two more are under construction for a PY member. I would like to see if anyone else would be interested in one while we are building the other two. The includes the bracket (blown or unblown, stands, and drive hub for the BOP sprocket) You use a pump mount extension, all standard. This is slick, simple and professional way to accommodate the fuel pump drive.


Any questions please ask. I can email pictures, I probably won't post any until we see if this is something I am going to have to get protection on.

Moderator: I thought it was best to start this thread under the race section rather than the "for sale" section since this is more application specific and would be seen sooner than in another section.

We are also asking for other ideas that might prove helpful in the accessory drive department. Please contact me with any other ideas/items for consideration.

Do you have a picture? I assume its designed to fit the standard hex drive?

Are you using the 4 small holes on the cam pulley or do you use something else? Just curious how tough it is to remove and if my pulley needs to be sent out to be modified?

How much, and when will one be ready? Im not sure Im set on buying one but I looked at building a cam drive before I bought my waterman drive kit. I like the fact that I can remove the belt to prime the fuel system without running the engine. I dont think I'll need to do that very often but I can see where running the pump without the engine to check for leaks would be nice.

It is designed to fit a standard 3/8" hex drive, so everything is standard. I am using the adjustible pump extension from RCD Engineering. Its really slick. You can adjust it from 6" all the way down to 2" I believe. I also use a quick release on the pump.

We do not alter the BOP bolt pattern. We do need the sprocket for the process. The idea was that if you decided to stay with the BOP belt drive, but no longer needed a drive for the fuel pump, that you could still bolt a the pulley on for a front mount distributor. We have also looked at building a drive hub that would serve as a pulley for a front mount distributor, if someone wanted that.

I had some other pics I sent another member (who we are currently building two for now) that showed it installed on my engine, but I can't find the pics.

If we had some more interested in these we could save everyone a little more money :)

FYI: this pic only shows the plate, not the rest of the assembly.

Very cool stuff, Ken! :hail:

With some further interest in this product I am trying to get some better photos uploaded.

I also want to mention that we are offering this for blown applications and another one for unblown (injected/other) applications. The price is less for the unblown version.

I am also trying to have one of each completed and available to Wade from BOP Engineering to be on display at his booth at Norwalk.

A member and customer, Bill Takanbe, will have his race car on display in Portland at the GTOAA event this weekend sporting the new blown version. Check it out if you can!

Thanks Vin :)

Can you make some that will drive a vacuum pump off a serpentine kit? Eric

Can you direct me to the serpentine kit you were thinking of using?

Yes, it will be a Billet Specialties kit for a Pontiac with A/C, and power steering....it will also have an 8-71 BDS Supercharger ...probably just wishful thinking. I have no room on the crank for a mandrel drive....getting too close to the radiator/fans. something to think about. Eric

OK, I will look into it

Thanks

So do you have a BOP belt drive on this engine?

Actually the engine is still apart. It will have a Billet Specialties pontiac serp. system with A/C and P/S....and the BDS blower drive system....I don't have any pics cause the motor isn't built yet....just trying to "think ahead"....Eric

cam driven fuel pump
 

yea I like the idea. I may have to when i get my Supercharger since i really want to go with a crank mounted style. Still would like to see pics of it assembled. and Like we talked about going to remote water pump is not a problem. BOP has the adapters if needed. :D

Sorry, I misunderstood your question....no BOP drive...Oh well, back to the drawing board! THANKS, Eric

HEre is one of the blown kits..

BryansMtn...Should have a pic of the unblown kit soon!

Some pics of the plate for unblown applications such as MFI injected, turbor centrifugal supercharged engines.

From now until 1/1/12 we are going to take $100 off the price of the kits!

$650 for blown kits!

$550 for unblown kits!

I know this thread is pretty old but wondering if these plates are still available for both blown and unblown setups? I would be interested in one of each.

Hi Jim,

This is an old one!

We had sold all the other kits, well I have one I've hung on to for myself. I could reach out the the machinist and see if he would like to make another run of these, but would probably need a few other interested parties for it to make sense.

I wondered how many set-ups were sold in that 11+ years?????

Tom V.

Agreed, maybe someone has one they never used.

I have the Front Plate and a BOP set-up someplace.
Probably covered up by Holley & Rochester carburetors, LOL!

Tom V.

Tom

If you are not planning to use that stuff and willing to dig it out and sell it let me know and I will send you a PM with my phone number.

I will look tomorrow. The engine plate is easy. The rest of the belt drive stuff will take some looking.

Tom V.

Good News. I have all of the parts.

Tom V.

Not so good news. He wanted a fuel pump drive system for a Pontiac and I had a
Belt Driven Camshaft Drive system from BOP Engineering.

Tom V.

Tom, as you know, sometimes you need a part designed and it's justified by selling a few more. As is the case here. I wound up selling several then pulled the plug on my racing program at the time, so I never pursued making any more. It only makes sense for someone if they are running the BOP belt drive, and need a way to drive a large volume mechanical pump. I think we only made around 10 kits.

The machinist I used was hit pretty hard by covid, I spoke to him today and it sounds like he may have some remaining pieces. If there were to be more interest, it's likely we could produce more.

I bought this kit years ago as I added a 10-71 Roots blower to my engine and it works great. I highly recommend it. When I documented my blower conversion in a thread up here in this section years ago, I thanked KGTO and a few others here who made parts for fellow Pontiackers and sold them at a reasonable price. Couldn't have done it without them.


Jim

That is very good news for people who want to go down that path.

Hopefully you can make it happen again.

Tom V.

Thanks Tom and thanks Jim, I value the input of both of you!

We shall see what happens moving forward, happy to be a part of the success of others.

I would be interested in an unblown setup as I’m running turbos. Please let me know if you make another run of them. Thx!

Quick update as there has been a little more interest. Looks like we have at least one of the turbo plates and a couple of the drive hubs. The machinist I used back then confirmed, but thinks he might have another plate. He was hit pretty hard with covid and doesn't go to the shop much anymore, he also lives 2.5hrs from me. I'll be following up with him again later this week and see, he was going to the shop and look to see what else he has.
