Default losi 350 in 8T 2.0 not enough speed for tripple..

last night i was at the track, and im getting good power out of my losi 350 thats in my 8T 2.0, i have stock gearing, 50t spur, and 14t CB. im about 1-2 feet short of the backside of my jump, so i don't need much to clear the jump.

ive tried to get good corner speed for the large jump, but never seem to get the right speed. my engine temps are warm for the losi 350. im usually running about 250-260 and my low needle is set pretty good, the temps drop as i stand still and idle. also, running byron 30% nitro 11% oil.

should i look into going down to a 48t spur? i have good power, and a good clutch, but not enough speed for the big jump at my track.

Going to the 48 spur will give you even less rip coming out of a tight corner.

You might be upside down on your needles. try leaning the bottom and richening the top. Jumping technique is important as well. You want to be using the throttle to compress the suspension going up the face of the jump.

It depends on alot of factors. First of all are you hitting top speed before hitting the jump? If not then you need to gear it down, go to a 13t clutchbell if you haven't already, if you are running a 13t clutch bell try a 52t spur gear. If you are reaching top speed before the jump then you can go the other way to get alittle more speed. Also you might want to think about doing the turbo head conversion as i hear that gives the engine abit more power that could help you. Another thing is how you are launching off the ramp. A little bit of preloading on the jump might allow you to clear it. A few minor adjustments here and there might make the difference.

The 350 is really probably under powered for the 8t 2.0, you really need abit larger engine. The 350 is fine in a buggy but they include the 454 in the truggy for a reason. Its much heavier and can use the extra power for clearing the larger jumps.

I have a go engine in mine and can clear anything i've thrown at it. We've got a huge double jump at the track i visit and i can clear the second jump by 10+ ft without trying. Its basically a triple turned into a double for schort course trucks.

I thought 13t was the stock clutch for the 8T.

try a 13t clutchbell, give you alittle more low end rip, might get you 6 inches closer to clearing...lol., but seriously, alitttle better motor would do wonders for you, 350 was meant for buggy. but still a pretty good mill!

I didn't see that you were running a 14t bell. Go back to the 13t bell.

I vote new engine and 13t clutch bell. But changing to the 13t might be enough to clear it. But also preloading the suspension prior to takeoff can help some as well.

Default 350

I got 2 of them 350s an one is Turbo head and re10 pipe and it runs 8:30 on one tank and temps at 225-230. Does that sound pretty good, and what does the re11 pipe do for and engine?

shit i don't know what i was thinking, its a stock roller setup. the reason i went with the 350 was i broke 2 Axial .28 cases back to back, and wanted to get away from that and get a solid block.

only reason i went with the 350 was fuel economy.. i have the 13 tooth, whatever is factory.. but its just not enough. it sounds top speed when i case the jump, once in a while it clears, but i have to be rolling just right to get it. usually i'll land right at the crest of the rear ramp.

and also, i chose the .21 losi 350 because i THOUGHT.. the RPM's were higher in the 21's than the 28's.. if im wrong, i might be interested in finding a take out 454.

so stock 8T2.0, with buggy losi 350, running 50/13. right at 250*.. maybe a turbo head might give me extra speed.. couple more RPM's?

its got alot of power, just not the top speed. i jet out of corners, and im running soft gridirons.

i'll make some LS & HSN adjustments as suggested.. but i don't think im going to get much more out of this 350. it sounds like its screaming down the straight, and not much smoke out of the pipe down the straight.

You got yourself a non V-Tec D16 when you really needed a tuned K20......A good .21 will do what your asking from it, but unfortunately a Losi 350 is one of the mildest of the .21's....
