We are delighted you have found your way to the best Jet Boaters Forum on the internet! Please consider Signing Up so that you can enjoy all the features and offers on the forum. We have members with boats from all the major manufacturers including Yamaha, Seadoo, Scarab and Chaparral. We don't email you SPAM, and the site is totally non-commercial. So what's to lose? IT IS FREE!
Membership allows you to ask questions (no matter how mundane), meet up with other jet boaters, see full images (not just thumbnails), browse the member map and qualifies you for members only discounts offered by vendors who run specials for our members only! (It also gets rid of this banner!)
So if you are tired of stepping on really hot snaps/carpet, or tired of that musty carpet smell - Marine Mat is the best alternative out there! Get in on this now, or pay more later!
You only have until September 30th to get in on this.....So Hurry!

Funny! Not worried about power though, worried about the DOT! Does Amazon have somthing for them?BLACK 3" Electric Turbocharger/Supercharger Cold Air Intake Generator Amazon.com: BLACK 3" Electric Turbocharger/Supercharger Cold Air Intake Generator: Automotive
Why worry about weight when you can just get this?!?!

You should watch the video from Cleetus McFarland. As hilarious as those things are he recently got a high output version to throw on one of their beater car just to see if it made any power and as a joke and they picked up close to 20 whp IIRC . It made like 5 psi lol!!

I agree with others the haul device is a gimmick for most cases. You’re better off getting on of those hitches with the tongue weight gauge made into them. Of course you wouldn’t have bed payload but at least it would be an accurate measurement for tongue weight.
The product is an Interesting idea. Will not be very accurate/precise and in some cases may be far off. For that device even how the driver drives is an x factor. Now if the vehicle had a series of strain gauges a device like this could get readings from those that would be far closer to what they are claiming. I am not aware of too many vehicles will strain gauges at this point in time.
I agree completely. Calculations can be made. Tires, tire pressure, fuel octane, wheel alignment, suspension wear, and so forth will impact accuracy. Getting the g force map for a given pull is easy. Getting the pitch and roll mapping for a given pull is easy. Computing down to within 10% of actual weight in the bed, on the tongue or being pulled will not be consistent across vehicles given all of the variables.Using accelerometers and gyroscopes can be quite accurate if done properly. The methodologies were developed to help spacecraft navigate in 3 dimensional space.
Remember the old "G-Tech Pro" devices that suctioned cupped to your windshield and would give you 0-6, 1/8th and 1/4mi times. Back before all of our handheld devices had these included, they were high tech devices. I tested one of those over about 10 vehicles, and found the largest error was about 10%, with cars in the 13-15sec 1/4mi range the most accurate. A 10sec truck and an 18sec car gave the most erroneous readings. Using this same premise, calculating the additional weight in a "before and after" test using full steam acceleration would be somewhat trivial. Beyond that though, all the lookup tables involved, and "adjustment factors" to account for all the different parameters would lead to excessive error IMO.
Looks like it will work, but I would question it's accuracy. I definitely question it's value. Getting weighed on a set of CAT scales at the local truck stop only costs a few bucks and some time to get it done. Far more accurate for less money.
Using this to get tongue and trailer weight correct for trailer load distribution would however be a mistake IMO.
