79.8 GPS both in dash speedo and GARMIN....also was a sustained time not a fluke out bouncer that tagged a 79.8 for a split second. Two people / half fuel / 1-2 foot chop / 70 degrees/ no wind. This was Saturday Oct 1, 2005. Now do these other boats have a set back box ? Like the ITS XR ? |

Open bow or closed bow ? Set back boxes ? Early HEATs were not stepped either but I am not certain what year they added steps to the hulls. I think it was around 1999 or 2000. Keep in mind that we were getting 76-77 at first 20 hour mark with a stock 28P Bravo. Now at 53 hours, cooler air temps, very low humidity and prop mods we are seeing 79.8. |
Re: Mhale00 & Raylar Kit
My heat is a 99 no steps. I think they added the step in 2000.

Re: Mhale00 & Raylar Kit
Dave,
When are you coming into Richmond? I remember us talking about getting together when you were in Baltimore. Your in my back yard. Call me and lets get together. I will take you for a boat ride if you can squeeze it in. Plan on an afternooon on the James River if you can. |
Re: Mhale00 & Raylar Kit
LIOPA...the boat was a stepped model with a stock 496HO and Bravo drive. I tested many props too. Congrats on your numbers, looks like Nordic has a real winner there!

Re: Mhale00 & Raylar Kit
I have a 2003 heat 525EFI XR drive, with 2 people 73 GPS on lake MIchigan in hot weather.

Sorry LIOPA, don’t mean to sound negative; Just friendly conversing :drink:
I know personally what hp it takes to run anywhere remotely near 90 at Havasu and it won’t be found in a naturally aspirated Ilmor. I also know Lonnie :rolleyes: Great run on the 496HO at sea level and on salt. Neither Steve (INDY) nor others have been able to duplicate it nor will a mere100 hp add 10 mph to that impressive number. We live at 4500 feet and boat between 4500-6200 feet. Your customers Heat would do good to approach 70 in these parts. It’s quite a humbling experience when boaters come here. Note though, all the test I have listed in this and other threads do not include any high altitude numbers for obvious reasons. Also, I’m not totally unfamiliar with saltwater…see below :evilb: |
Re: Mhale00 & Raylar Kit
Understood Dave,
All I can say and post is what these guys are getting on GPS. ....and yes have seen it on board myself. I am truly surprised others have seen such low numbers. The offer is always open for anyone to come out for a ride if you visit this area. We are trying a new prop on that 28/525 boat this weekend. I'll let you know what happens. Paul NICE 25 BTW....what was in it? |
Re: Mhale00 & Raylar Kit
Hey Dave,
The 525 BTW is very under rated by Mercury Racing. They DYNO higher out of the box than the stated 525 HP....more like 540-545. The 496 HO is on the money at 425 HP...so the gain is closer to 120 HP. On the Nordic, Ultra, and Velocity 28's 12-13 HP = 1 MPH in these parts. Which makes more sense on the speeds being seen here. |
Re: Mhale00 & Raylar Kit
I have heard about 1mph/17hp which is about 6mph for an additional 100hp.

NON step with 415pshp. Your are correct.

Re: Mhale00 & Raylar Kit
I'll have to ponder that offer :drool:
It would be much easier for Steve to jump on board for a quick spin beings he lives there and had run his stepped hull Heat there for three years. It's not only mathematical equations but the results of 25-30 other Heats and yours is in a league of it's own so to speak :eek: Maybe they should send that boat back to the factory and see what it is that makes it so different from every other Heat out there. If they could dupicate those numbers consistantly they would have themselves a Howard Bullet with ample room :drink: Now that would be a winner!! Not so much doubt; the bigger question is why? Dave :cool: (If Steve can't, maybe I will) |
Re: Mhale00 & Raylar Kit
AGREED.......Dave.......We were surprised at all the numbers the boats here are getting....I would love for the factory to explain the difference other than altitude and salt vs fresh water..... lol
We also just might get really really tight motors from Mercury purely by luck. I have heard that there are significant performance differences from different production runs of the same motor. The better ones coming off the line just after a fresh retooling at the factory. Who freakin' knows. |
Re: Mhale00 & Raylar Kit
I thought we were talking about my bad raylar experience. :eek: LMAO. The info is on the way.

Re: Mhale00 & Raylar Kit
At 80 MPH, I'm turning 5450 with a stock 30" Bravo 1, running an ITS and XR drive. This on glass smooth fresh water. My boat is an open bow, so I guess the slip could be higher because of this or maybe the salt water is a lot more dense?? I dunno....One thing I have discovered. I can turn about the same RPM whether the water is slick or choppy, but the speed can vary 4-5 MPH. So, it seems the HP is there but with really slick water the boat runs like the anchor is out. I've never experienced salt water with a nice chop in cool weather. My boat might run 100 under those conditions. Just more food for thought.

Re: Mhale00 & Raylar Kit
Ok. I had the boat out yesterday. The wind was blowing about 30 mph. but I had to get out and look for some flat water.
I took Rays advice and had a 1" spacer added. They also adjusted te fuel pressure. The Lowering the drive I think made the difference.Seems to be something heats would need to do. Very fast onto plane. Maybe 8 seconds. Oh yes, I had to fill the tanks as I was taking out 3 ladies and figured to be going quite aways up the lake. 4 people, 3/4 tanks, 1 cooler full. 30 mph wind. 3 ft chop in the basin, 6" chop in the narrows. 8 seconds to plane. fast out of the hole 69mph GPS @5100 rpms. Friday in havazoo, Arron took it out on glass, 1/4 tanks 2 people, it ran 70 GPS @ 5100 rpm I think I might see 72 in Just the right conditions. I have to wonder what would happen to a stock 496 ho if you just add the 1" spacer?If you could pick up 3-4 mph by just doing that, It would be a hell of a lot cheaper than adding a raylar kit. I wanted to get back out today with just one other person and check speeds and time the mid range as well but the wind was blowing all night and is expected to be 40 mph at the lake. I will get out next weekend if not after work one day this week. |
Re: Mhale00 & Raylar Kit
Now its time to detail it and sell, so I can order a 35 flame w/ 525's. Yes, it does seem like alot of work, just to turn around and sell it. But I wanted it for the summer, thats why I ordered it in April and expected it done by late may. So much for that plan!

Poker Runs America did an in depth study of salt vs. fresh water performace a year or so ago and the result was NO DIFFERENCE. You might get more bite out of salt water, but it's denser and will cause the prop to spin slower, and yes the boat sits higher (fractionally) but it take a little bit more to push it. The opposite is true in fresh. It was an interesting study and the bottom line was that temp, humidity, and elevation play much more into performance than fresh/salt. If anybody is interested, I'll try to find the issue that the study was done, good reading and it debunked a big myth. |
Re: Mhale00 & Raylar Kit
Hey Steve....let me know what issue. Does sound interesting.
In the list you posted add wave/chop conditions also play a big part with stepped bottoms as well. |
Re: Mhale00 & Raylar Kit
Never could figure out why the Heat does not run real fast. Nordic really hit the bulls eye on the Flame. That is the best acting boat I have seen with very good speed. I wish they would straighten out the Heat. There are a lot of people not wanting a twin but wanting a Fast single.

Re: Mhale00 & Raylar Kit
TRUE linster........it is the mosty requested setup lately .... a fast 28-30 with a single 525 or ILMOR 625

Just adding a 100HP to any boat is no guaranty of 8-14 mph unless the drive heights, prop type and pitch and blade thickness are sometimes optomized to realize the horsepower addition. I understand that in talking to a few Nordic owners with your hull that adding a 1" drive spacer to your hull with the right prop has gotten them to be able to use the extra power and increase their speeds about 8-10mph with more power. Make sure you have a specific conversation with Aarron at Absolute about this item. The drive spacers are easy to add and apparently it corrects some x-height issues that have been plaging some Nordic hulls like you have. Raylar has had to many tests and confirmations of big power and speeds increases to know that our kits make 525HP. The problem sometimes like this is a hull that needs drive and prop tweaks to utilize the extra power of the motor. After Aaron checks the boat and motor I will have him GPS test it on the lake and confirm his recorded speeds. Some hulls, drives and props take a little more corrective action and tweaking , but a 100HP increase should net you more than 4 mph, I agree! I feel your hull running the right prop , drive ratio and x-height at normal weight should see about 1 mph for every 12HP which equates to 8mph and I think thats where you should be. Sorry our earlier production could not keep up with more timely shipping, we just got behind back in April. I also know Aaron got behind on the installs because he was buried with kit orders and other committments. We now have kits instock in good quantities and we ship all orders within two or three days after the dealer or buyer pays for the equipment. My apologies, no excuses we did our best, sorry for the inconvience and the trouble it caused you. Best Regards, Ray @ Raylar Any similar spacer or other recommendations for the Rage to improve hp transfer? Thanks! |

They will run, but typically not the way the factory sends them out. They are using a very high X-dimension for such a large single engine boat. This setup lacks the hydrodynamic lift needed to free it up with moderate horsepower, and it is still weight sensitive (placement and load) with horsepower. That's why some people are having success with drive spacers. It (high XD) does work better as the horsepower and speed goes up. I've worked pretty hard to get mine to 85. I used the Imco case to load the prop, and the P5-X to get enough blade area to lift the boat. The factory should make everyone aware of the P5-X prop. It does help the high X dimension issues (slow holeshot/high propeller slip #s) tremendously. The older padvee Heats ('99 and back) used a much deeper X-dimension that gave better all round performance. On the other hand, it is a great looking, smooth riding boat with a spacious cabin, for it's size. I think the step is just too conservative to be of much help freeing the boat up. If you look at the steps on the Flame, they are much taller. Another small step on the Heat, or increasing the height of the existing step would help tremendously. My best friend's 29' Fountain has a single step in the same position (fore and aft) on the hull, but it's much deeper, like the Flame's. Just my 2 cents............... Regards, Steve |
