Well done my friend Whatever it is, I'm sure you put up a gutsy showing as a privateer.

Questions... Team Serpent changed to a ball diff setup in the last qualifying rounds for that kind of track. I saw that you had a solid rear. Did you try using a ball diff in the rear?

Also, I noticed that you used the 17T side pulley option with 47T diff pulley and 22T brake pulley. Any noticable difference in acceleration? I believe the MTX-3 has a higher final drive ratio (hence better acceleration) on a tight track...

I also see that you got a new J-Tech engine How is that compared to the RTU?

sneezer714, the part number for the new 17T pulley is 801252.

The pipe combo depends on the size of the track you run and rules your track follows. The NovaMega TP04 (2183) pipe or the polished version (2184) coupled with a 2195 exhaust manifold gives good low end torque. But the NovaMega TP05 (2185) and the outlaw version (2186) gives an overall better performance. Before the TP04 and TP05 pipes came out, team drivers usually use the 2690 inline pipe set meant for the larger .15 engines.

I prefer the inline type as I do not have to mess around with couplings. I notice that in almost every race, at least one car will go in the pits to get the coupling fixed correctly.

we were actually about a day ahead of the serp guys in suspension setup and gearing... figure that, they really worked the worlds setup to see if they could get fast times before they went to the yellow rear springs, and my guess is they used a bit less rear toe, the problem with the solid is getting the car to turn in quickly, with the ball it will turn very very fast, and the track had a new top coat so the groove was almost none exsistant until the second day of quilifying..... i choose to stay with the solid, my qual was with marty and barry, and the few qual laps i did put in i ran right with they pack( never finished a qual, blew a motor first qual and never got the spare quite right) ..

on the 17 side with the 22/47, yes huge difference if you are running on small track( as ft myers is not very big( not a huge straigt in any means) and you have a lot of corners to pull out of it is great,

the car was a bit doggy out of the corner and very hard to peak down the back straight... worked much better with the lower gears on this track....

I also ran the old two speed and the old centax in the 705 when i built it, since i was already in the middle of qualifying i did not want to mess with shift point issues so i used the old stuff, and i used my entire front pod off the old car... plus i had a lightweight shaft on the old centax...

the j-tech was my buddies, i ended up throwing it in the morning of the mains( as it never worked well for him) , my richy was well worn out and i could only get 4 minutes of run time, plenty fast but hungry, so i pushed the needles too far and finished her off on the last qual( aluminum melted out the exaust port) , i ran that rtu at houston, cinn nats, and cinn worlds, so she had earned her keep, and i had only brought as a spare motor.... the jtech was a bit flat, and the motor my buddie ran was a ms that i had done a lot of work to, and it was much faster and snappier, after we were done we tore the jtech down and were a bit dissapointed on wht was done, some port work, very minor, and no crank work what so ever... but it was okay for milage and not the reason i lost my main.. and would definatly be more than enough for the average guy, i think it was fast enough to go two more mains even with the bottom too rich like it was..... and there was probably a half a second faster lap times if i just tightened up my lines.....

Andrew, so you basically did an update to your PRO with the 705 basics (chassis, tank and upper deck, etc) during the race itself? I believe most of the parts on your PRO were already with the good stuff... Didn't you de-commission the PRO?

Ummm, if I were you I'll strip the RTU crankshaft, carb and button head (assuming they are still in one piece) and put it in the J-tech...

I basically did a update to my pro in the middle of the race is correct, my race buddy and i were only able to get one car before the race so i did not switch, as i thought and still do that there is no major diff in the cars , in fact we both ran the exact same setup and had the same results with both cars... but on wed night we needed a servo and had asked a local hobby shop to stay open while we drove there, while buying the servo the guy noted the 705 was not assembleable without a exacto knife and he could not even sell his last kit, i looked up asked how much and took it with me, 8:00 pm i starteed building while waiting for the pizza to show up at the hotel, by 1:00 the car was on the tweak boad, and guess what, same shocks un moved, same exact tweak and left right weight distribution.. i really liked seeing that as my pro would balance left to right on the hudy balance tool, so did the 705....

all of the problems associated or complained about on the were not any diffenerent than any serpent car i have assembled, a bit excessive on the flashing but the part fit was fine, they have never been begginner cars, but true race cars...

the car was perfect when i put it on the track in the morning, that qual i ran my fastest laps, but ran out of fuel at the 4 minute mark.....was looking to be a fast 21 maybe even a 22, same on next qual....

I can get more than enough out of a ms motor with some port cleanup, flow work and a crank timing cleanup..... and keep it very reliable, it will make more power then the j tech, and run forever, the rtu was great but it is a long rod motor, and if dennis can send me a new piston adn sleeve( if he has them or can get them ) it may even see more races, but otherwise it will just be a fond memory of some terrific racing i have done... as i said it has more than earned it keep

the sts is being reassembled and i hope to use it for quite afew races, and i can not beat that with a stick, in fact i am even interessted in selling them as i feel they are a incredible deal for the average racer.. and very fairly priced...


oh yea biggest reason to get a 705 is easy to work on the motor tank and battery come out extremly easy, would like a upgrade to the battery mount front though....

i was able to swap motors in 15 minutes, including clutch on friday morining wen i realised the richy was totaly shot...

Yes, I forgot that your RTU was a MT-12... Dennis did mention that the crankshaft timings done for the RTU MT-12 will be off when you put it into a short rod engine.

I found that with the "new" styled pulley mountings on the 705 are easier on the belts. Especially for the front. You are also right that the engine is now easier to switch without the old style rear left brace. Also, the battery is easier to access. I also particularly like the new style tank. I find that fueling is easier. Don't know why...

Are you having an STS engine or the STS PRO II kit?

Hey guys, I have decided to back out of my Serpent deal. 4 guys at our track have had 705's for a few weeks now and each one hasn't had a full days racing without snapping a gearbox layshaft. Is anyone else having this problem?

Wouldn't want to get the car yet until all the gremlins are sorted.

Snapping the layshaft as in the main 2 speed shaft? This is strange. The stock shaft is not a hollow shaft. Solid. I have not heard any problems like that on the Serpent 705 forum at mytsn. Go and have a peek for yourself. You can be sure that almost all 705 owners take a peek there to find solutions or get tips there.

The only problems that people are whining is the roll over bar (is breaks at the point in contact with the graphite upper deck), the battery support breaking, the side 18T pulley at the layshaft (the pulley rubs on the rubber sealed bearing can on some occasion melt the bulkhead and bearing) and wrong printouts of the manuals on certain parts based on Serpent's morbid assumption.

Those are pretty mild problems except for the 18T pulley one. But then there's a simple solution to that which is to glue the 18T pulley to the aluminum pulley adapter so that the side flange does not rub against the bearing. Make sure that it spaces out well. Putting a shim there may also help. Replacing the rubber sealed bearing with a steel covered one would also circumvent the problem.

But no, no layshaft problems that I heard of... If there were even the slightest of problems with the car, you can be sure that these people will bring it up in the mytsn forums...

YEah. I check MyTSN all the time. I am even a member for the last 3 years. But seriously, all the 705 cars at my club have been snapping the 2-speed layshaft clean off.

I guess it must just be our killer engines.
