First Dyno Complete Take 3
 

:poopoo:
Hey everyone,
I will try and end this the best I can. I am making NO changes to my engines. It's not a "finger" at anybody. That was never my intent....ever. I know there is a wealth of knowledge here and I have learned a lot and even made some purchases based on my time here. (Yes, I realize the irony in acknowledging the "wealth of info" and then not taking it.) I've given advice (not on this site) to people before and never did it occur to me to be "offended" if they didn't follow it. We all have our reasons for the direction we take. You shouldn't have taken it personally and definitely shouldn't have gotten so pissed off. In the end you guys are not responsible for what happens or the expense should something happen. I'm as surprised as some of you are at how "personal" this got. I did have the 2 hour talk with my builder and I'm going with his word that I'm good. I know this will go as "fish food" too but I also called AFR and spoke in depth with a guy and he also said I was good. I just wanted to show my dyno results and talk about them. I also didn't know on this site 1,000 hp is the new 500. I thought I was doing pretty good. :D Live and learn. It was pointed out that 500hp is no big deal and I believe that that may be the reason my engines will be fine. Maybe at 750 and up things get way more important? I'm not a builder so I don't know for sure however I'm pretty sure that this is or could be true. Some of you guys are probably very, very good at building so much so that maybe an average guy can't even afford to go to you. I think that's great however, everyone on this site, to me, is a stranger. I didn't and still don't think it's in my best interest to blindly follow the opinions given here on every subject. I mentioned before that I'm sure regardless of your business, you don't welcome a customer that points out that you did something wrong based what they saw on the internet.
Now, by a show of "LIKES" to the first response to this post, who is now more pissed (if that's even possible) than before? Again, I just wanted this to go away.
I was hoping you guys would just wish me luck and be done with it. Some of you did exactly that, and I thank you. I thought that was the best way to go because at least that way, you didn't know if I followed some, all, or none of the advice. We should have been good but damn, you guys are really swinging hard for the fence for really no reason. I didn't do anything to you. I thought it was free advice. I didn't realize once given I was obligated to follow it. Again, live and learn.
Someone asked why I didn't buy something ready to go and that's a great question. When I was looking, NOTHING was in stock and no idea when they were getting anything. I take that back, one place was selling 572's but I didn't want to tear my boat in half so I passed. I did not check the referenced engine number in the post but where I looked there was nothing.
I did befriend a member or 2 from this site. I will not mention their names however I will stay in contact via email. Lucky for me seeing how I have been "blackballed" on this site. I still need someone or somewhere to go to ask my questions.
Not much more to say. I am disappointed that this happened.
This just added to my ****show and some of you will get yet another laugh from this. I emailed Holley a week ago or so because I wanted to know where to connect on the QFT M-800 the clear hose from my stock belt driven fuel pump. I think its there in case the pump diaphragm fails? This was there reply: Thank you for contacting Holley Performance. This Carburetor is not equipped with the Vent for the Fuel Pump. While this is a Carburetor made for Marine applications, it is not Coast Guard Approved.
Not approved. I'm sure it was in the fine print and I just missed it. Just when I thought I was good to go. I do not require any responses for this even though it's posted as a question. Maybe this is good info for someone else.
Watch out for new members. I'm going to come back for a fresh start with a new name. Same dumb ass questions so you may figure me out. I will NOT be posting any graphs though.
If you are MORE PISSED remember, don't like this post, that might make me the most popular guy on the site and we all know that's not true. Like the first response.
Really this is just to prove that now that you know for sure that I didn't take any advice about the engines, is NOT BETTER than what you thought you knew.
My first response was never intended to piss anybody off. I had hopes that it would just fade away.
You guys have a great site but the learning curve is a *****!
Bummer for the PQ family as I think there's only 3 or 4 left now and when I come back I think it will be as the only Bayliner member on this site.:champs:
Thanks for all the comments on my other posts, even you Dan.
This has the feel of "Deja vu" You too BAJAMAN or F-2?

It's all good man, we are all here because we all have one thing in common , we are addicted to boating , good luck with your build, first time out on your boat will make all this worth while

You can get flame arrestors with the fitting for the mech fuel pump vent/overflow.

You can drill hole and thread in a nipple with pipe thread to some arrestors. Show a pic of the arrestor you have.

Fine, I'll say it...... POST WHORE :angry-smiley-038: :cartman::party-smiley-004:

Good luck. Make sure you have sea tow or similar.

I can see a pool starting.

I truly wish you the best on your endeavors. Don't be afraid to reach out with questions to our shop. We're pros, it's what we're here for.
I think you'll find nobody is really "pissed" at you. And nobody thinks your 500hps are lame. BUT. You asked. We all answered. Some of us are pros, some of us arent. I get that. But we still answered. Your engine builder (and you) are now telling all of us we're wrong.
Not the best way to keep the advice flowing.
In your engine builder's defense- if one of my customers came to me after dyno day saying "yeah but the internet said this....", the look on my face would be the whole answer. BUT. I own my own dyno. Our engines win championships. And the only engine Id build with those pistons is a 350cid for a 32 ford.
Carry on and good luck.

That right there just gave me a chuckle:grinser010:

Your money, your time, your summer , you`re free to do what you think is best and you should.
I mean the guy with the first name bob and last name that start with an M that I can`t mention sold probably thousands of Stock AFR heads to unsuspecting customers telling them they were Marine ready to his specs (lol) and they were just stock ARF heads.
Pretty sure not all of his builds blew up so you got that going for you I guess.
Don`t ever wish bad luck on a another boater, so I`m sincere when I say I hope you have a good summer.. maybe take a really long time to break em in so they loosen up bit ?
:drink:

I'm sorry, but I hate it when I see a 350 in a Ford. Unfortunately it happens a lot.

Id like to ad to my post that my explanations for specing certain parts certain ways would not be a secret. Please feel free to go and tell the internet why we say they're wrong. In fact, if that were the case I would encourage you to do so.

I’m withholding my added comments until First Dyno Complete Take 5.

Saris,

I still hold that the builder is not so deluded as to think he's safeguarding any engine building secrets, but that he's attempting to control the damage of either deliberately or unintentionally building a couple of potential timebombs.

Thanks. Brad.

PQ290,

With that said....

Maybe you could convince your builder to sign on here and reply, defending his decisions and actions. It would be a curiosity, for sure. He doesn't have to divulge is true identity. Just convince us he honestly acted in your best interests,

Thanks. Brad.

At least there has been something to read the past couple weeks 😬

should we start a poll?

they run fine with no problems
valve sticks in a guide
rings butt and bust a ring land
spins a rod bearing
spins a main bearing

feel free to add to the list what will be the outcome

Boat wins class at LOTO Shootout in August. Deemed the new Cat Killer. "Here Kitty, Kitty!" Fountain owners sell en masse! :drink:

Saris secretly replaces their own mills with super secret builder mills in race boat. Chant "Tighter is Better!" on podium after each victory. :evilb:

Uummm.......On some things, tighter is better!

With the loss of valve control at higher rpm, and tight guide clearances I’m going with stuck valve takes them out.
If he runs them with 5-30 and 180* thermostats the pistons and bearings have a slight chance at making through a season. But more likely it will scuff a skirt first hard run.

Hey now I called it first! (post 6), LOL

yea but you didnt make a list

I am going with rings butt and pop the top land

These na 615’s were built with parts and spec’s gleaned from OSO, mostly without even posting. You can beat on them all day and they like it. You can also bet that if kooky info gets posted here it gets challenged pretty quickly.😄

I'm adding :
Never got them reved up enough due to chine walk.

Second screen names are not allowed on OSO and will be banned.

I forgot about the tight ring end gaps. Hmm tough call. Chicken or egg situation there lol

I'm going with... they run fine with no problems
A lot of tolerances on the tight side that I would not build to, but nothing saying that the pin has been pulled.

Honestly man, if you've discussed with your builder, digested what you've learned here and are comfortable with the path forward than I wish you well.

I can promise you, no one on this website is hoping you have issues. Everyone on here has been towed home, destroyed a drive, cracked a rocker, spun a bearing, lost oil pressure, had a head rot out, leaking header issues, etc.... It blows, we've all experienced it, and no one wants to see it happen to you just so they can say "I told you so".

Owning one of these boats comes with a complimentary PhD from the school of hard knocks. I'm hoping you don't earn yours this summer!!!

Well said.

One of the best sentences ever posted on here. It should become a sticky

not sure it is really 'complimentary' as you do pay for it one way or the other, it's just that some of us pay more than others

Very true. I know I've got a number of dumbass moments under my belt and none of them were cheap....

I am a firm believer that education never comes cheap or easy

Great point!

Knowledge gained is in direct proportion to parts ruined.
