Is this a serious question??

@@Chadwicky69 yeah

@@louied420chavez2 If you have a legit clutch & drivetrain setup...... slam the gas pedal to the appropriate rpm level needed to spin the tires starting in 2nd gear & side step the clutch.

I have another video where it spun it over 10,000 rpms, instead of 9100 rpms, and added some fuel for the hole shot. It sounded a little shitty at idle but picked up a couple tenths of a second to 800', which is almost two boat lengths in a drag race.

Well then.....this video is not for you brother.

I don't know what caption you are talking about.? I didn't type anything like that, as far as I can remember, unless I was drunk lol. It is a 200hp, not a 240hp. I don't know of any 2.5 Merc outboard that was rated @ 240 but let me know if they did. Btw, nice sig pic!

⁠​⁠@@Chadwicky69 I commented this on a KZbin short. KZbin glitched and put it on your video for some stupid reason. And the 240 horsepower 2.5 I was talking about was modified. It was a built racing engine that made 240 horsepower. It was on a Phantom 25.

@@UltraMagaFan2 Gotcha

10".....I just installed my 15" setup on it that adds right around another 2" of setback that is built into the clamp/swivel. Looking to see the difference between the two and if the extra setback helps in handling, trim angles, and speed.

@@Chadwicky69 Ok awesome. Nice Sportsmaster lower :) I have a Vista, similar to Voyager but smaller 18ft and its V-bottom instead. Changed from a Laser 220 EFI to an Optimax 250 DFI. She's heavier (510 lbs) so I'm wanting to replace my jackplate, used a 12" setback for the 220 but I'm finding its a bit too much setback for the weight of the Opti. Debating a 6" or 8" Bobs Machine as it's replacement. Thanks for your response, great video btw :)

@@86brown I would still go with an 8" plate minimum......My buddy has a Vegas with 300xs and I believe it has a 8" jackplate and it isn't enough. More setback is better if the boat goes on plane well, comes off plane well, and doesn't bury the motor while doing either. The less positive trim angle needed at speed, the better IMO.

Fremont WI....Sat the7th I believe is the date

@Chadwicky69 ah dang. Too far for me to make that one. I'm gonna be in wheatland MO next weekend for nationals diamond drag with KDBA, gonna be hard to convince the wife to go to another right after lol

I would have to look at the data, but I believe it was 9200ish. The other vid I uploaded after an intake swap and a proper tune ran up to almost 10,200. I raced it last weekend in better air and a better tune that netted just under 10,400 plus .03 sec faster ET to 800'

@@Chadwicky69 oh so sweet.

Thanx!

Life is too short and not having some fun & laughing our asses off is NOT an option for me! I have since added a sticker, on the front of the boat, that my buddy bought me which says "Loud but Not Fast" haha

Thank you!

A custom made clamp bracket with a horizontal trim ram.... That with a Merc trim pump, that I customize for different pressure limits, and then run it on a 24 volt UP and 12 volt DOWN wiring setup.

Around 90 mph....This was a test for the drag race class that I was setting the boat up for. It would go a lot faster but I am trying to get as much acceleration out of the rig for the 800 foot course. Motor spun 10,190 rpms with a different prop in my other video, while still too rich above 9500. Still have a bit of tuning to do haha

@@Chadwicky69 Make sure you are not running it to lean. Nice sounding engine.

It doesn't actually......it isn't responding to more fuel on the hit as well as I thought it would and taking fuel away doesn't work either. I ran a median amount on the hit and that didn't work for shit as well...starting to think that I will never be able to tune the launch as well as I thought I could with these pipes. Still a blast to drive and it PISSES EVERYONE off, so that's a bonus!

@@Chadwicky69 it may be better with running through the exhaust tuner , nice boat !

Definitely loud though !

@@TroyPrewitt-fm7ic I know it would be better through the mid but this was a fun experiment with these pipes and I am trying to make them work with my custom fuel curves as best as possible. I changed my intake on this video from the previous video I posted and it picked up power "basically" throughout the rev range but haven't had the time to clean up the launch acceleration......I will get it to the best it can be, although that may still suck haha!

@@Chadwicky69 definitely a cool experiment for sure , I remember some of the old Chryslers & inline mercs used to run those, STACKERS , really cool ! I hope it works out well for you .

I have another video where it spun it over 10,000 rpms and added some fuel for the hole shot. It sounded a little shitty at idle but picked up a couple tenths of a second to 800', which is almost two boat lengths in a drag race.

STV ModVP

@@Chadwicky69Is it a Roark Summerford, Wally Lamkin Triad, or Full Throttle build?

@@AUClay The last ModVP that Wally built

@@Chadwicky69 Wally was an artist!

@@AUClay Yes he was!

This was a fun experiment and no power gains were expected. Running two pipes took away some bottom end torque and high end hp but work fairly well in the mid-range. I wanted to run 6 separate pipes but they would produce even less power as each side uses the tuned exhaust from the 3 cyls work with each other. That's why "stacker" pipes are commonly put in pairs or triples......not to mention the logistics were pretty much an impossibility anyway.

24 volt up with a custom pump I built

@@Chadwicky69 show me the way

@@mattnetko2282 To???

Should do a video on the 24v trim pump set up

It's quick that's for sure!

If you are not moving and a bunch of water splashes into the pipes, it could easily get into the bottom 4 cyls and cause it to hydrolock but that would most likely happen if you were backing up or sitting still. It can be taken apart so the water could be drained and cleaned out if it wasn't running hard when it happened. Put it back together and run it for a while to make sure nothing inside the motor is left to make it rust. They actually have plenty of clearance if you leave it trimmed up all the way.....steep boat ramps is what I worry about!

That is a 1990 Merc 200 F block and the pipes were designed to be totally reversable. They actually make less power as they were designed to be a bolt on and after all the work it took to get the pipes to function as a bolt on, they still can't collect all of the exhaust coming from the ports, unless we wanted to make them permanent.

Either way, the pipes would probably cost horsepower over the standard exhaust chest and 12" mid setup I have. If you could collect 100% you may have a chance to play around with tuning to get closer, but I still doubt it. There wasn't enough time to test the motor on the boat before the pipes were installed. May have to try them after they are taken off and see........

@@Chadwicky69 I still think it's bad ass. One upping a Merc. Engineer isn't easy. Six big cones with on the fly adjustable length will gain something but the cost for a few HP up top is always high. The motor sounds perfect to me as is.

@@Chadwicky69 less backpressure maybe? its like those swedes that put that V8 Evinrude in a car and where very dissapointed to find it had no balls down low. im guessing for a similar reason.

Need expansion chambers-tune pipes. But that would be a bunch of stuff hanging out the back!
