Damn looks like when i purchased my boat I should of by passed the 6.2 liter upgrade and went for the big boy hell would of only been a couple grand more well live and learn..Ok on that matter which would give me the most bang for the buck. Already spinning at about 5000 rpm so i guess i could go to a tad steaper prop motor wise which is the best process...

Prop and that is it. Save your money and dont get the headers.
If you dont already have thru transom, get it.
Once you start messing with the motor, your relability goes in to the toilet.... If you dont mind wrenching then mess with it...

Thanx for the reply Kilrtoy Yeah I dont wanna loose the realibility,guess prop is my only alternative.Like I said earlier I'm spinning now around 5000 and thats with being trimmed
so I quess a little steaper prop probaly knock it down to around 4800.So headers aren't worth the price in your opinion either I see.I was suppose to have thru transom exhaust but a little mix up and it didn't happen,Now it is just a matter of gettirn my boat back down to aftershock and have it taking care of.??Think I'll pick up any speed/rpm's with a thru trannsom exhaust...

Thru transom makes a difference.on the top end of about 3 to 5 depends on the boat......

Hell I'll take 3 to 5 miles a day for freee anyday Better get it hitched up and down to the shop a.s.a.p.
Thanx again Kilrtoy

NOT TRUE RD
I ran against an Identical boat as mine to the T
thats T
except thru hull exhuast .
WOW big difference...

Hell who am I kidding I will add the thru transom exhaust just for the damn noise gets get out of stealth mode and if it adds more top speed to boot all the better.exhaust thru transom and a tad steaper pitch and 70 mph here I com (hopefully)

When I bought my last boat I swore I would be happy with the (5.7)small block. Well I wasn't and I told myself my next boat will definitely have a big block. The new boat has the 496 Mag and I still would like to go faster. I swear it's like frickin addiction.:rolleyes:

AN
Extreme Addiction in my case :D , sorry that's the name on my boat. I changed from through hub to through transom w/ Imco powerflows on my old Galaxie and noticed very little difference, maybe 1 mph, I also changed the ignition, dicked around with the carburator, and basically did everything I could do to a 350 mag without going internal. Total result was maybe 1-2 mph, and a big loss of relability. The Galaxie wasn't a very efficient hull compared to Kilrtoy's ShockWave or my current DCB so on another boat those upgrades might be more usable. It has been my experience that the headers and through hull don't make a huge difference on the small blocks. In fact going from factory manifolds to polished Imcos on the 454 in my DCB made very little difference but it loods cool so it's totally worth it!!;) :D :p Lots of cool people on this board with props who might let you try something different without having to buy.

Your best bet IMO is to go the thru transom exhaust route. Then take the boat down to whipple to have the ECM recalibrated for 91 octane. You might see 3-4 mph with these mods.....:D

I might be able to help. At K&N, we are just about done designing a flame arrestor for the 6.2L and it looks very promising for enhancing performance. We ran the stock one on our flow bench and found it to be only reaching 60% volumetric efficiency for the 6.2L @ 5000 RPM. Our new one will take you to 100% volumetric efficiency and according to Merc, the computer has a fuel curve programed into it that will handle the increased air flow w/out causing a lean condition. We have no real world testing yet but have talked to a guy that ran with no flame arrestor just to see what would happen and it made a significant difference in his performance. Would you be willing to haul up to Riverside during regular business hours? If so, PM me.

I'm going to call bullshit on 3-5 mph just from exhaust. Maybe intake, exhaust, new ECM, and a tail wind. :D

I had two friends that upgraded from through hub to through transom. One had a 454 mag the other a 454 330hp.
Both only picked up about 100 rpm and about 1mph..... But a pretty cheap 100rpm none-the-less.

When I switched my old Essex (small block powered) from through hub to through transom; I didn't really notice any gains in top speed. I really did it just cuz I got tired of operating in stealth mode.:rolleyes:

You should consider the new noise laws soon to take effect. Hate to see someone pay hundreds of dollars for something that may be just more trouble

Call it bullshit, call it what you want.
Im sure the x dim is pretty damn close on two boats if not the same. Ok, maybe one prop had more of a bend than the other if that makes all happy.
It was two bone stock off the shelf motors. Were not talking about to super high preformance boats here.
That was the difference in speed 60 to 63. I STAND BY THAT BULLSHIT.:yuk:

Actually im referring to the person above you.......
The other parts you posted are just explaining maybe how the difference was attained. I understand that

Being the boat business for longer than probably most people on these boards and doing a lot of rigging, blueprinting, etc over the years, I wouldn't say a 3mph jump is impossible...though it is highly improbable without other modifications. We have done this on numerous boats with stern drives and outboards, and it gives you the sensation of going faster or a "seat of the pants" feeling of going faster. Gps is the only way to really know because speedo error comes into play also. I have a boat I can take out to my local lake and running north shows 2mph slower than running south, explain that one, but that is on my speedo, not GPS. So RD, you are right and Kilrtoy is also right, kind of...:D

Maybe the increased sound levels slow down the GPS signals?

Kilrtoy
12-30-2003, 07:18 PM
Here is how it goes.
We are at a dead stop
He hits the throttle first, then I do.
I catch him right away and pass him. After we are done I was running 63 and he said he was running 60 and continued to pull away from him(ALTHOUGH it was very slowly).....
All the other stuff, I have no idea about......

The other night I started pounding my old lady at 9pm, my best friend in Ft Worth started pounding his old lady at the exact same time. If we both stop at 9:30, which of us was pounding the hardest?
Clue...my old lady has bigger tits.:D

I'll call bullshit all day long on a 3 mph gain with just changing out exhaust, unless there was something wrong, like 3 or 4 of the passages in the exhaust manifold were blocked off. In that case, you might pick up 4 mph, again, with a tailwind. :p :D

Kilrtoy
12-30-2003, 07:43 PM
Well Im wrong
GOD HAS SPOKEN, I mean jordy same thing right.
We are talking about 3 mph.....
Now if I said doing 80 in my boat with a stock 454 I can hear the bullshit.
but we are talking about 3 mph on a slow boat(compared to most on her.
So tell us all about your boat jordy, I havent heard about it for a while.......

I bet it's been a year and a half since I've started a thread about my boat, so no you haven't heard about it for a while.
It's a jet and has over the transom exhaust so it's 1000 mph faster than one with through transom logs. Is that what you were looking for? :p
God. ;)

You're always right. You tell me... :rolleyes: :D
Aside from jokingly giving you the satisfaction by adding "God" at the end of my post, I've never claimed to be.
Why don't you look at all the other posts that don't buy those gains by just adding through transom exhaust? Maybe one of them thinks they're GOD too... :cool:

I don't think I'm cocky. But I am CONFIDENT that you won't see those gains without some other factors coming into play.

Once again you are right
That day I spoke of never happened. I just woke up and realized BOAT GOD(JORDY) has spoken the word of the lord, Amen brother.
Wow all over 3 miles an hour at 60.
I feel sorry for all those people out there that think there boat may go 125 when in fact according to JORDY it is impossible, it can only go 124.445 MPH

I suppose that all depends on what kind of exhaust they're running... :rolleyes:

Well we added through transom exhaust on our old boat. 99 Essex Sterling 350 mag. We picked up 2 - 3 mph & thats no bs. 60 to 62 - 63 mph.

She is not to areodynamic,
If I get rid of her and put over the transom like jordy with a velocity stack and gps fish finder it would have been 5 MAYBE 6 up HILL(OPPPSS I meant up river)

RD, the Y pipe war removed & the stock risers sent out the transom. I didn't run it through the lights w/ a back-up pass within the hour. j/k I only ran the boat one weekend after I did the exhaust. First pass out with 4 adults in the boat, we picked up 2-3 mph on the top. I don't know where the moon was at though. I sold the boat to Mtdewdrop, it runs very good & sounds better. Well worth the $ I spent. Wish I had installed it sooner.

You're suggesting a 5% gain in top-end speed! Not an insignifigant gain in the world of boating. I'd look first to fuel load/total weight to explain the differance, or at least the majority of the differance.
This is my last post on this subject. (I thought I had to say that).
