RE: Thunder Cat 31
when running (lean) this will cause more heat as the fuel will also cool the engine if the problem persists you can cool the headder by raping copper tube around it run cooling line like this pick up to head to exhaust cooler to water outlet i think there are some pic s of this setup i the thread if you need them

RE: Thunder Cat 31
cooling pipe is ok because i check it continuosly when i m running my boat and water circulation is ok but i wonder and search if HSN is lean?on the other hand after each tank of fuel i check my engine temperature and its ok.no problem with that but why HSN is drop down to ~1 i want to find this and if its normal i forget it and keep on running with my boat.

RE: Thunder Cat 31
there are a few things we also have to consider is temp outside and also altitude you run at because i run at two different altitudes and there is a 1/2 turn difference between the two ponds running my hull today i was at 3 turns out and it ran great but it was 60 deg outside lots of air if i run it in july i find my setting around 1 3/4 turns out to about 2 1/4 turns out hot humid air i like to be on the rich side for the simple reason a fat engine cant be hurt but a few passes with a lean neadle and you wil be spending $$$$ also rember when your engine is under a load it will lean out a bit so set it up a little fat on the beach

RE: Thunder Cat 31
welcome back Asmund, and Erolos, good luck and dont give up...the tc31 is a fun boat to play around with I know a few were looking around for a different carb to run on the dynamite as well, and Asmund was using a different one than what others have tried....an ASP .91 carb if I recall...

RE: Thunder Cat 31
I have now changed my Dynamite .32 for a Sirio Race .27 buggy engine, Jammin JP-1 exhaust, Octura M445, Rapicon 60%. Air-cooling works great and I could remove the draggy water-pickup. With this set-up the boat litterally flyes along the water, I have to let go on the throttle sometimes to avoid beeing airborne. I will radar it as soon as possible, but I have a good reason to believe that it is faster than my previous personal best of 45 miles on the modded Dynamite
I know this for sure, I will stick to air-cooled buggy engines and have a wide selection of relatively inexpensive very powerfull engines to choose from. Now I am trying to decide which one will be my next engine, LRP .28 Spec 3, LRP .30 Competition or the Picco P3 .28, all of which should be even more powerfull than my old well used Sirio (used to be in my buggy before)

i would like to see your new projects detailed photos and of course videos.on the other hand i have a bad news from my side today i broke my dynamite 32 piston rod but i dont know why because i didnt push too much when i run my boat but later i saw many rust inside the engine so may be its from long term salt water corrosion? anyway now i need a new piston rod or a new engine. but the question is which engine? i like dynamite engines tiger drive systems very much and i dont want to leave this practical operation system so if i buy different brand 32 engine can i use this system on it?

I really don`t know about that, but the Dynamite is quite a decent engine. I couldn`t kill mine and I ran it as hard as possible. Maybe the easiest is to fix the stock engine again if there`s spare rods to find out there?

RE: Thunder Cat 31
I ran my TC 31 again today and swapped the Jammin jp-1 pipe to a new STS 0403 that is a top-end pipe as opposed to the JP-1 which is a bottom-end pipe. The boat was noticeably faster and actually was quicker from the start and on the pipe too, this was a little surpricing. The best pass on the radargun was 83 kpm ( 51.67 miles) This is the best for me so far and now I will try a M545 instead of the M445.
Set up right now is: Sirio Race .27 buggy engine, ASP .91 carburator, STS 0403 tuned-pipe, Octura M445, Rapicon 60% fuel.
The buggy engine holds up well and works like a dream, aircooled and all

RE: Thunder Cat 31
so i finally took the boat out the lake this weekend, set screw fell off the prop on start up so it sat on the bench all weeknd.
could someone post a pic of the low speed needle ? i brought the manual along but was unable to locate the low speed.. found the idle and high speed no problem tho.. on the opposite side of that was a nut then throttle arm so im confused.

RE: Thunder Cat 31
the low speed needle is a pita at the carb arm the needle is inside you need a really small flat screwdriver to adjust the exhaust tends to get in the way
