My Endele 80 a 1 appears to have laid down on me. 2 questions.
1- Can these pumps be satisfactorly rebuilt?
2- I have an Enderle DSR 1 billet pump that is suppopsed to be in good shape
can I swap it in place of the 80?

1) Yes.. Enderle will rebuild, replace parts as needed, recoat, flow, etc.
2) Yes, an 80DSR is only about 1 to 1.5 gpm more than an 80A-1.
I'd have to look up the specs to be sure, but it is pretty darn close.

Hey, I thought that boat was coming to KY Lake this year.

Hi Steve,
Yes the boat was supposed to be ready lots earlier in the year, but as our buddy Leland says, I had a bad case of the "sorry asses". If I can get it figured out by next Spring I will try to see you guys. I know the KDBA had a great year. Changing ignition and pump trying to chase down a mid to high rpm miss/pop. Thanks for your input.

Enderle 80a rebuild $140.00 at Enderle.

Wags, would the other pump need to flowed to the existing sustem or just tune downstream from the pump?

After checking out some things I discovered that I had a high speed lean out in the fuel return. I'm hoping that my miss was too much fuel in the hat. Gonna try it before I change pumps out. Must have been drowning it in fuel. My driver said when he would nail it higher in the rpm range it was blubbering and when he would back off the throttle it was trying to pick back up.

Is this an alcohol or gas deal? If it's alky, almost impossible to to have to much fuel. On our boat, we run alky, everything through the hat, no high speed, 80A-1 pump and it works great. It's a 565 and runs 7.70's at 140 with a 8-71 at 4% under in our flat. Super simple and very responsive to tuning. Good luck!

I am a tune and go guy. Some guys won't put together a fuel system without having it "flowed" by someone.
If I put on a known good 80A-1 in place of a suspected 80A-1 I'd run the same pill (or adjust per air) and see what happens.
With that being said... I'm a fair tuner in the bracket stuff. Not bragging, just a ton of passes under my belt. Some others with less experience may not be as comfortable with my ways.

Steve, congrats on your SITC win. Very impressive.

Fiat, I'm running the tune up you advised me on and once I got the right check in place it 's great. Only problem I'm having now is getting used to that first big hop before it takes a set. I'm an old hydro guy and flying the nose scares me. Used to the nose going down and the tail going up. I'm sneaking up on it though. Kind of hard to cut your teeth on a light weight TR2 with a blown alc inj BBC, first flat bottom ever in. Been in both seats, out over the side, on the deck and in the floor so far, but not wet, (knock on wood).

Back the blower down. Nothing wrong with underdrive. Fuel curve with that system does not have to be changed much. That is the beauty of it.
Smaller gear is easier to drive also but you can only go so far.
Consider a smaller prop that will burn more....which gives you more time to set the boat.
Make sure you have enough plate travel. Every boat is different. Sometimes the through hull interferes so you need a different one or make one. You need 2 inches of travel at the plate at least. I prefer 2 1/2".

You have to leg these things big time at the hit and back out some and all that just depends on each individual boat/prop/gear/hp setup.
I know where you are coming from. Takes a while.

I forgot to add something. With as much as you have to leg one of these deals....it is REALLY important that you get the seat right. You need to be over top of that down peddle for best control. It makes a huge difference in controlling the boat out of the gate.

More like 30 years of valuable experience. ;)

Remember I sent you a PM a few years ago when I was just starting into my first Vdrive and I said, "I only know just enough to get in trouble"

You responded, "That's all any of us know"

I never forgot that one. :D

And I very much appreciate taking advantage of them ;)

First off, congrads on the SITC win Wags. That's cooler than hell!! As far as fuel systems and stuff, after you've done it a while, it's pretty easy. I'm still getting comfortable with the deal.
I will say, as a newbie, you gotta start with somebody's tune up and hopefully they know what the hell they're doing. I started with a tune up from Enderle, but thought I'd need a lot more blower than I did. So they gave me what I asked for, which was a good starting place for for 1500-1600 HP. When I finally figured out that was 500 HP to much, we started backing it down. We had too much pump and the tune up got really soggy because I couldn't return enough fuel. Fortunately, Bob (Fiat 48) took pity on me and basically gave me a tune up that works perfect for a bracket boat. Very safe, simple, tune-able, starts easy and don't crap up the oil every pass. And damn if it don't make some power!!! :)devil
