MER mark did a similar build. I mentioned it earlier in this thread. 555ci, afr 335s, solid roller of similar duration from MK, big dominator on a victor intake, made 720ish at 6000. That was the one that was suppsed to make 750hp. Ultimately, it made 760ish, after the MK cam was removed.
800hp, seems a bit optimistic for that combo to myself as well. |

I didnt want to comment on his ad. Whats approx 800hp with proper intake mean? Was it dynoed and made 800hp with a different intake? Looks like a nice build.
Do some digging and you'll find it went 90 or so in his Nordic Rage. |
Fast hull and light

Omg.

Just saying can't compare hp and speeds in that to mine, I'm just saying I seen claims of close to 800 hp and results show different.
I should just add boost and call it a day haha

SB, what is your power and speeds? What boat? Is it comparable to mine? Or that?

I thought that MT was a gravel hauler? Does he haul rocks or not, because this is pertinent to whether I follow his advice or. It.

61 pages!
Will we see 100? :circle::circle: |

I feel same way, 93 in a flat fountain with 468's not bad...

I'm following his advice and will post results. His boat is proven that he has some sort of idea what to do. 468s making 800+ that have been together for a while and 90+ straight bottom. Where's yours?

People call him a googler, gravel hauler, etc., yet he was the only one actually in the Dyno room helping Tim. I've only found his advice to be sober and substantial and the ad hominems here can get pretty retarded. And I'm just trying to get this to 70 pages by the days end. |

That's why I pointed it out along with being a next step up so to speak from your engine, some more cubes,more cam, more head,more compression,and more induction. Anyway, that RAge went 90mph + at 4500 ft elevation. ============================================== I was not comparing speeds with your boat, I mentioned that because the 800hp may not be believable. So...........forget the hp # quoted.......if you take a 25ft Rage, run it t 4500ft elevation, and it goes over 90mph, it is no doubt making some steam. What hp does it take to do that ? I dunno.....I'm not figuring it out now.....I was thinking you'd look into this. Some more cubes, more cam, some more compression, and more induction. |

I don't haul gravel anymore, but I do still "google". :drink:

Truth be told, this stuff simply interests me, like many others here obviously. 10 years ago, it was simply about getting on the water, and boating. Last few years, its been more about tinkering, and getting on the water, to see the results of my tinkering .
I like learning stuff from others, reading books, experimenting, and so on. For myself, it would be no fun, to have someone spec out a package for me, and call it a day. I'd rather fail myself, then have someone fail me. My boat is far from a show piece, and the speeds it runs, are far from impressive by todays standards. Their is however , a certain satisfaction that has come from gaining 17mph or so in a 38ft boat, without changing shortblock combo, changing x dimension, doing any hull mods. Basically, just changing induction packages over the years. One of the main factors I bought those engine quest heads, was one, my research showed they are a very capable cylinder head. Two, nobody really was using them here in our community. Three, the price was very reasonable for a bare casting. I had no interest in an off the shelf assembled cylinder head. I bought them, flowed them, had some work done to them, flowed them again, installed on the engines and ran the boat. Overall, the data shows they were a good move for me. That made me a happy guy. The problem I have sometimes, is often we write things off, without actually testing, or trying it. Computer programs, simulators, math calculations, and all that only goes so far. Its awesome when you have guys here testing and trying things, and reporting the results. https://www.youtube.com/watch?v=zrbGDNR5Bxk&feature=youtu.be |
Okay, how about Jwurl's from MER ?

Here we are now with the Holley HP set-up. Edelbrock intake, 2000 cfm TB, same cam. 690 PK Torque, 714 Hp. Custom, ECU and electrical bracket, center plate adapter to replace Holley's, that includes regulator mount. Harness was a non-terminated, with a new non-terminated 6' 12volt engine harness

And,only 7cid more than the 565, is a MER 9.5:1 572 that made 823hp corrected, 808hp observed :

This was the first of 3 Holley EFI Systems, I have done so far. This system has made a believer out of me of it's simplicity of use, navigation of program and the operating speed of the ecu. The closed-loop learning is instantaneous, during the test pulls. Comparing the learn A/F with the A/F of my dyno acquisition data, is so close. Synchronizing the spark/ fuel tables with the ecu and from the ecu back to program is made simple. All spark/fuel changes made while online, with no shutdown or delays, makes back to back test a simple task. Once you have the final test; the file is saved and then transferred to the matched engine. This system has a dashboard which you can change the gauges and values to what you need to observe. It has data logging, with a overlay for transfer to your spark/fuel tables. I am a strong believer in this Holley EFI. I have stayed away from EFI tuning for the fear of lack of tuning knowledge for EFI systems and have had to rely on someone else calibrating the ecu in the past. Always having to wait for someone else, time involved, travel and being locked out of the ecu just wasn't my idea of building power and tuning my package. I have to thank Alex Haxby, for his start-up program and help through out. Once I was ready; Alex, took over my laptop from Vancouver BC here @ my business in SC while he demonstrated and explained the process and navigation. I really thought; it was going to be some big complicated task, it turned out to be pretty simple. I just finished up a 383 using the Stealth Tunnel Ram EFI, which I was able to pick a base calibration from the Global Folder then make some minor changes. Start-up was fast and smooth from the firing of the engine, I will post it up once we get the video finished. I don't want to highjack this thread with the 572 build, so I will start a seperate thread on it with pictures and details of the project. https://www.youtube.com/watch?v=THTwkuWLpCE |

I am like joe also, do things myself some issues and some guys hate me bacuse I speak my mind, claim in stupid and don't listen, well I do listen, my engine build came out ok in the end besides the part out of my control, I took heat for issues and nob bashing, I don't regret it at all... I learned a ton though so that worth it to me.. Still learning and boated all summer doing it!!

Intakes need to go or at the very least opened up and flowed. They've bothered me from day one threads. Not to be or sound like an azz but it's kinda like putting perfume on a pig so to speak. 4500 carb would undoubtedly help however I've seen identacle carbs as yours on same cubes running higher rpm with another 100hp. Street and strip engines though. Get those janky azz intakes off. Other good 4150 intakes to choose from if you have to.
Not good to go 4500 intake with 4150 carb from my experience however other way around seems to work well. |
I have a 4150 carb on a 4150 intake not a 4500...

I'm a simpleton but I can read. It likely had the MK cam swapped out and made more power. Just a guess.

I'm pretty confident mine is not right for my application

You can swap out a cam on any build and get more power. Don't mean it is the right cam for the application .

Seems to be a theme around these parts of the MK cams underperforming or causing valvetrain damage. It every one of em but more than enough. That my personal observation.

Compression tests 175 low to 178 high...

Hey SB. I know you and I have stressed this topic a bunch, but anyhow, I been playing with the pipemax program tonight.
Holy chitballs. It's amazing, what a 5200RPM 454 likes for exhaust header design, vs a 6000RPM 700HP 540. Sorry, but until I see otherwise with some solid dyno data, I'm going with the theory, that Tims Stainless marine basic manifolds, are choking the hell out of that 540. If I had my choice, and that was to buy new intakes and dominators, vs buying a good set of headers/tails, I'd be doing the exhaust before anything. |
Speaking of exhaust
At the Sprint Cup race this week-end, on Saturday I noticed alot (maybe all ?) of the Modifieds using 4-2-1 headers. Sunday for the Cup race we arrived late, blew thru the garage area, then pit stop row to see all the driver's getting up on the stage, and then going up to the suite it don'd on me...fuk ! I forgot to look at their exhaust. Oh well, will try to remember next year races. So, talking with a few guys with the modifieds, they said the primaries are sized by the exhaust port, ie same size as port but if tubing not available that size they use size as close to exh port size as possible, then primary about 10 inches or so, stepped up to next diameter. They too, said the collector was really where they found the power. Of course, they all have merge collectors too. |

Talking to wags 382, he built some big blower motors, made 1200 or 1300 hp, put them in his boat, had efi, transom black, gassed up oil, screwy afr readings, 02 sensors kept telling him it was rich, cmi 1 7/8 headers, he knew they were too small but figured he would just be down 30 or 40 hp. His lbs of fuel per hour at .5 bsfc was telling him he was only using about 1000hp worth of fuel and boat was a pig and slow. He built a pair of almost identical motors for a friend, guy had stellings big tubes, boat ran fast and flawless. Last i talked to him he was upgrading the exhaust, it was screwing up his ability for motor to breathe so bad it was killing power. Im sure hes not the only one suffering from mismatched exhaust, his 02 teadings kept telling him it was still too rich and boat was down on power, fwiw, smitty |
You can run 4000$ heads and a big daddy cam but air still has to get out!!
