If that was a jab --then you're pretty thin skinned! If you would have read all my post before you got defensive, you would have saw that i said to' tell your buddy to break out a couple more thousand' because he won't get any help from that guy- (not that i would want it).
I feel sorry for your buddy -- i know what it feels like to pay big money for things and then have to pay again-as do a lot of other people on here--- that's all i said there -- maybe i wrote it wrong ...or you read it wrong. I'm not putting you in the middle of anything.

You mentioned about Wolfies-- I not sure what you people call 'fresh' because he said the same thing when i called and told him the brutal leakdown test results and cylinder scores, before i even started the motors---- he won't build a briggs for me! end of story.

PS. the other shop was great to deal with -- no problems at all

Tell you're buddy good luck with his engine, I hope he rectifies his problems, the people on here are a wealth of knowledge.
Now go take a deep breath and relax.

Your right I read your post wrong, I was in a hurry and On
my way out and interperated a few things wrong.

You have my apologie's and I edited the post above.

I'm sorry for what ever i'll feelings you have, just asking
that you leave me out of it. Call him or Wolfie it you would
like to pursue other avenue's.

As far as the cylinder scores didn't you run an entire
season before, you found the problems? I'm not looking
to argue, just seems I remember they were making
great power for you, but one was using oil. And then you
where going to have head work done and found the piston/pin
problem upon tear down.

Wolfie has alot of BIG Client's, it just puzzels me.
And happy one's for that matter.

Also I don't feel Rich mislead you by the hours. They were left in the boat until a final sale was made so who ever bought
them could hear them run and or perform. You were
satisfied and asked that they be pulled.

Rich sold them to move up to 588ci, not because
of any other reason. He would have eventually had
the same delima you had after a full season.

They made 500hp on the dyno and you got the pair for $12,000
total for a fully accesorized engine if memory serves me.
Seems like a very fair price these days.

This guy paid $5,000 for a used blower, carb and install
for 4 wonderful hours of use.

Once again good luck, sucks to see anybody having
engine problems!

Well it was torn down, dropped one valve.

Wrecked the heads and they are ( Iron / merlins )
Looks Like he might be switching to Aluminum.

Checking the compression out for sure to find out what it is.
They are domed, and was told they may be anywhere
from a 9:1, 9.5:1, 10:1.

Block seems to be fine after a magnaflux, but will have
to be bored.

Strange part is the valve springs are broke on
6 out of 8 pistons? What would cause this?


Thanks

It could be weak springs to putting a bigger cam on old springs to detonation that did it ,,he needs to know comp,, 8.75 to 9 to 1 is good and good cam ,,,blown 1500 has a great set of brodix heads 704-574-4020--get a good cam you'll gain the 12 mph just be sure fresh 91 octane gas and 6 to 8 lbs boost ///no thermo,,,
it will fly

SSComp

Sorry to hear the bad news. New heads, new pistons, new cam...she'll be screaming.

cougarman

The cam was never changed by the first individual that
did this install.


Wouldn't 8:1 compression be safer for everday
boating?

What kind of power would you expect to make
with 8:1 with 6 lbs of boost?

Or with 8:1 with 5 lbs of boost?


Thanks cougarman

SSComp

I've had 65 reliable hours.

I'm at 8:1, 4-5 lbs generating 550 HP on 468. Same compression and set up on your 540 would be about 650.

If you are taking the time to do it right Dyno it.

bobby daniels

AH ,but that low of compression makes the blower on a heavyeir boat stay in boost more and when I run 8:75 or 9:to 1,,,the motor does more work and uses less fuel and less heat ,and leaves harder ,its just my personal favorite way and works great for me and my friends ,,I really need the whole package to give good advise like weight of boat,cam,heads,piston type ,ect.

you could be safe like merc and their 575 and run 7.5 to 1 and no boost and only 575hp just so you can have a warranty and say you have a supercharged boat ,

12 mph min improvment is normal and the min. any less and you wasted your money on a blower

cougarman

Can you better explain the reason for running

2 Carbs VS. 1 Big dominator.

Thanks
Cougarman

bobby daniels

The main reason is more even fuel distribution . mianly on the larger blowers the little 250 its not that critical and I often run a 1050 or 950 of corse with indexed power valves and it works great ,,,also the linkage is much better with one carb

we run total air flow and are sure the single carb fits the application ,also
