Hey Ed +100 on the customer service

Any chance you can get any hats or shirts to motorama thanks

edd will be at motorama and I know he has alot of stuff he is bringing. so theres achance he might have shirts

Any suggestions on getting some more mileage out of my JS full mod. I'm using a 6.5 restrictor, 9901SS, 41021 pipe, OS p5. Ambient temp 60-70s. Engine temp was 210, but I stop checking after my first 5 or 6 tanks, so I don't know where it temps now. I just know it idles well, drops to idle well after a throttle pull, and it feels very strong on the track. I did some testing a small medium grip track and was able to just get 10mins with my current setup. I was able to get just 10mins on a large high speed track also, but I was holding back to make my pit window. (20 min race)

In comparision, I was getting 12+ mins on a different motor I've run for years in the same buggy. The JS full mod is very smooth, and it spools up faster than my previous motor. It really has more power than I need on the bottom and everywhere else for that matter. The only problem is my mileage has suffered.

I have the idle gap set 1 1/4 turn from closed and set the low end needle with that idle gap. Does this hold true for a smaller restrictor also?

If you have any ideas please let me know. There's large race coming up next week, and I'd like to make 11.5min pits. I was able to do that last year, but this year I may have to settle with an extra pit stop.

Ernest hey man i was running 6.5 restrictor in my race prepped js and a 086 dyn pipe and its stupid fast but was coming off track in 20 min main at Nitro pit at 187-190 ..... was only getting about 7-8 mins I know i need to lean it out but didnt know where to put it since it had so much power LOL also have a p4 plug in it now ..... i know Wheeler is running race preped JS and he is using 053 pipe and 41021 header and his Losi is AWESOME!!! i have a 053 now may try it and see if my milage goes up and oh yeah i moved to a 7mm restrictor now because 6.5 was way to touchy in my car .... Good luck with it man i will see you at NC thnx Will G

Ernest,

Im running a 6mm restrictor and a steel flywheel along with one of the softest clutch set-ups you can put on the losi to smooth everything out which ultimately increases mileage as well, Don't forgot not only are you running a different engine then last year but also a different car and that can also play a roll in fuel mileage. I know you know the drill but the smoother the drive train the better mileage is and clutch is a major part too. I believe a 3 shoe clutch gets worse mileage then a 4 shoe and I know of at least one other person who switched cars as well and saw a drop in mileage so has went to a 4 shoe to help get that mileage back. I'm not sure if the JQ has a 3 or 4 shoe but could be something to look into.

I agree with everyone... I use the stock HB clutch in my D8 and have been getting 10-11mins pretty consistently at 200' 7mm venturi, P4, dyn 086, sidewinder purple stuff. I could eaily lean it out and get alot better mileage, but not sure if I can drive the power

I have a werks clutch Ive used and run the .9 springs on that.

It was a good tiime at motorama an a bonus too see ED and all of those .23 ripping down the straight . Talk about a beast of a mill WOW
Can't wait till my mills home Thanks ED.

thanks for the feedback guys. based on everyones comments I'm going to guess it's one of two things. It's my combo of pipe/head/plug or it's my tune.

I've seen Chris' mileage on his race prep and I was amazed. That's what finally convinced me to try a JS. I already have a soft 4 shoe ascendancy steel clutch, and my drivetrain feels free. An A/B motor swap was 2 extra minutes on another motor I have with the same chassis.That's the extra time I'm looking for.

So I'll lean the tune somemore and maybe try Chris' pipe/6mm restrictor/plug combo.

thats pretty much same setup im using tony and im getting about 10-11mins except for this past weekend at motorama i was probubly getting 9 but was a little rich and didn't want to touch it.

if you work on your setup and get it really dialed in FOR YOU, then 10 min pits are made easily, 11.30 pits is really pushing it i think but maybe possible for some ppl on some days.

Joe,

If anyone can get 11:30 Ernest can lol he is smooth and precise on the throttle and the complete opposite of my driving lol

I was getting about 10:40 on the layout that was at the pit Ernest and that was at 200-210, maybe the 53 is a better fit then the 01 I know the 53 is the power pipe so maybe the 01 is just choking the engine too much and hindering mileage? just a theory and something to try!

I'll give that a try, I have an old 053. Also, I still have my unopened race prepped I was going to use for the truggy class. No truggy class for me this year so I'll try it in the buggy. I'll match you're setup as close as possible to eliminate those variable.

Also what's you're FD on your losi? Stock ring/crown with clutch/spur 13/46 on small track 14/46 on big tracks?

Good points. I do have areas I can work on that I'll try and address before Wednesday. New motor, new car, and little time to get everything dialed in. My backup plan is settle for 9:15-9:30 pits.

If it's not my pipe combo, than I think I just need to learn to tune this better. Honestly I haven't gotten to the point were I just keep leaning until I see/feel a performance loss and back it off and fine tune from there. The motor runs very strong already, so I stopped at that point. I don't think I have that 99% tune yet.

you'll notice the bottom bog off the corners when you've gone too far in on HSN, then i back off a little at a time till it stops bogging. then after its been running 15-20 mins i fine tune the bottom. after that its ready for 60 mins straight but can take awhile to warm for a 5min qual.

you AZ guys gtg your hands on a 2041 to test.
