I wouldnt send it anywhere until you have someone that knows how to tune it checks it for you. After reading many of your threads and posts I would just about guarantee its the tune.

Also, tuning by sound only works for some people, others need to tune by smoke, or feel, and most by temp.

Not everyone is sensitive to sound
when you are tuning to sound you are also looking for the right amount of smoke and power. You cant tune a motor to just sound.

His engine needs to be checked and sealed..He cant do that himself, plus the faster he gets the V-spec out of his hands the less likely he is to ruin it more

yesterday i would argue the same thing. but last night i checked my clutch and everything. Backed it out to factory settings. VERY rich. This is where i mess up. I had to be very patient to get it started (doesn't like to start on factory settings) set my idle screw. Did figure eights spitting smoke and fuel till it got up to 180 (as high as it would go). then tuned the HSN FIRST. That has been a big mistake for me in the past i would try to tune both at the same time even though i new better. Tuned it down a hour at a time till i got good but not superb top end and the engine in the 220 range. YAY!!! i am getting the hang of it. Time for the bottom end. Didn't need much there just a couple of turns and it was a monster again!!! I usually overdo the low end. So there ya go, everything is just wonderfull agian. So until my next screwup i will see ya later and thanks to all!!!!! going to the track now!!!:t ire::tir e:

With my 2.5, I can tell just from the sound, if it's too rich, or too lean... But only at idle and full throttle, after a couple seconds... It takes a bit to wind up in my STR.

Tuning to temp is fine if you are driving your TMaxx through the parking lot. Tuning an engine to temp on a race track is just stupid.

Just got back. I am starting to realize how easy tunning really is. My friend (who has a mbx5) finally came out with me and spent the day. He has been doing it for about 15 years. There is absolutley nothing wrong with my car or engine. Its funny cause i ended up buying the exact same engine, radio and car (well mine is a 6) and i didn't even mean too, so we didn't miss a beat. Yeah i dont mind the temps to much but every now and then i would check when i would fuel my tank or check it to get my temps up. and usually when i would check it was after i was satisfied with a good trail of smoke or a good crisp sound when i rev it off the starter box. so yeah tunning to temp is stupid but when you are a beginner its good to have it to help you go in the right direction until you get the hang of it. I don't think i will need this thread anymore, besides i know when it is getting to hot or if it needs more gas. anyway i think i can finally close this thread. THanx to everybody who has helped me and now if i talk it will be mostly about setup, and things of that nature (most which i will take to the mugen thread)

don't get mad if i ask questions sometimes random and off the wall that is just the way i am. I will use the search function but sometimes i have to sift through alot of stuff to find what you are looking for, but i will try.


Its funny cause yesterday i was sure my car was done and was fed up. And today everything came together like i never thought it would. Just funny

ok. steering servo. lots of play, more then when i got it. I would think some play is normal. Is that right??? It's a jrZ650 it was only about 60 bucks, i will get a hitech when i get the money. I think i have a couple more weekends left on it then i have to junk it, cuz thats what it is.

Also the friend i was telling you about has a ferroni (spelling?) center diff with a 26 tooth spur that he puts with his .30 engine and a 12 tooth spur but when he races he has a normal .21 with 13/46 setup. I have never heard of this before. Is this normal?? He also has titanium sealed bearings throughout his car and feronni aluminum shock towers. Pretty slick. Is it the less teeth you have the faster you go?? I thought the bigger clutch bell the more top end you have and the the smaller more bottom end and the smaller spur more top???

Going down to a 26t spur is just like going up (ALOT) on the clutch bell. He does this to counteract the huge .30 engine, but I have no idea why he would run anything other than .21 for practice.

Dude, a .30 is for sled pulling or hillbilly drag racing.

Your MBX6 with stock gearing is great for a VZB. The stock towers are fine as well; lighter and plenty strong. Fioroni makes great stuff, and back in the day it was practically necessary to make the K-cars upper echelon. Now a days, the cars are super competitive with the plastic/carbon fiber components.

Buy a Futaba BLS352, or if you want to save a few bucks on a great servo, get a Hobbico CS170 (identical to a Hitec 7995). The servo you have is a budget analog servo, which works just fine, but are a lot slower than the digital servos of today.

he keeps his vzb in his car now pretty much all the time. He hardly ever races anymore. When his kid comes to town he pulls the car out. And to help me of course. And yes he used to drag race.
