I have a new RC10GT Ready to RTR - I've been through 10-12 tanks of nitro, to it is broken in. The high end speed and power is good, but low end power (bogs down in grass fields) leaves something to be desired. What can I do to improve the tuning and low end performance. Can I expect wheelies with this CAR?

ericheller

you need to adjust the low speed needle, bogging is a sign of lean settings. try richening the lsn in 1/8 turn increments untill it doesnt hesatate to take off. you should be able to wheelie with it.

MrSavage

it depends on what kinda of bogging you are talking about, gurlge bogging is too rich buyt if its cutting out, its too lean.

thejimmster

The motor does not cut out, but the car does not "take off" in grass like it does on the street. Maybe its more a gearing or clutch issue. The car does not stall or gurgle. If i run it in my yard (grass) I can give it full throttle sometimes, the engine revs but the car or tires don't spin.

thejimmster

I thought the richer you make the mixture of gas, the lower the power & performance?

ericheller

no the whole concept is to tune it in to the right spot where you get the best performance. bogging is too lean, slow exelloration is to rich.

when i get my truck started, i just shoot for the high pitch noise when u pull the trigger when its juuuuuuuuuust right!... ahhh i love that noise!!!!

MrSavage

no eric, actually, generally, the richer it is, the poorer the performance than if it was leaner

thejimmster

That's been my experience. It seams the leaner I get on the high end needle, the faster the car is. I'll keeping tweeking.............

ICrashThings

thank you someone said it.

ericheller

but if its too lean it will cut out and there will be a major loss of performance. atleast when its too rich it get close to full speed, when its too lean it wont, just cuts out. my engine is usually at its peak performance so any leaner and it looses power.

Try change the clucht with MIP 4-1, this make your engine increase rpm before engage with the bell, give more chance to move the tires.

other and recomended only (IsaidONLY)for experts [>:]and if this do not works think in modified your engine, this will make more horse power and RPM( open ports, open headers, crankshaf modified ect ect) But take care becauce if you do this wrong you will loose your engine

My Feedback: (1)

My engine's peak performance (too lean!) would run it too hot after 3/4 a tank so I just have to settle for lower temps and longevity...

ericheller

if its running at its peak then it isnt too lean.

PornstaR16L

Actually thats quite wrong..... I build and tune "real" cars. I have just finished a 91 turboed integra that runs 9s in the 1/4 mile with 700 whp. Anywho tuning is always the key with any engine to get peak performance. Lean will run faster and quicker response (to a point) but with that you sacrafice the longitivity of you motor with high engine temps. Rich will keep the motor cooler and last longer but wont have as quick throttle response and will load up much easyer when purging throttle. Just my .02

I bet you like to change alot of exhaust manifolds/headers if your leaning out your turbo car.. when you install a turbo you need to have a much larger than stock fuel delivery system. the turbo does the leaning for you, to compensate and not to "lean" you need to deliver more fuel. If your running nitrous and a turbo, i hope your spraying water in there too, cause thats gotta be hell on the intake, and the exhaust manifolds. An integra that does 9s you mean in the 1/8 mile?

ericheller

nitrous and a turbo would be too much for the small inline 4. did you put a prelude motor in it? and at its peak its not to lean, maybe for your preferences. it wont last as long but thats just the way it is, a engine that is ran way to rich will last for a real long time. btw, hondas werent ment to be drag raced, thats kinda a disapointment when the car could be on a real race track. imho it takes alot more skill to corner.

madblunted

Thats why they make water injection, it does provide a "safety blanket" as it lubricates and cools at the same time. But yea I have seen nitrous and turbo acuras, but thats alot of money to spend to get into mustang territory.

ericheller

if your saying that mustangs are fast you are wrong. i dont think they actually inject water directly into the engine, that wouldnt be good.

flyingjibus

where do you come up with this stuff?

I mean come on...was that just said to dig on mustang guys? or are you the end-all-expert-on-all-dragracing-guru? cuz if you are thats a pretty ignorant statement, but you are no stranger to those are you? Hah, I love it!!!!! we can replace the losi vs associated argument with mustang vs any other crap, ahem, I mean car. this is great. eric you are the greatest source of entertainment I have at work!! thank you

ericheller

dude mustangs are slow, and i do know alot about drag racing, my uncle has a 8 second car, and ive been around cars my entire life. you seem to be the ignorant one.

ICrashThings

lol i like reading what eric posts, makes me feel better about myself[&:]

ericheller

i want to appoligize to the author of this post for getting off subject.

ICrashThings- whats that supposed to mean?

ICrashThings

oh nothing................[sm=surprised.gif]

flyingjibus

any car can be made to go fast. that is the only fact about brands and speed in drag racing. I too have been around cars my whole life, and I have learned that you cant just make a broad statement like that. what if it was a mustang with whatever motor/tranny combo you like in it? would it still be slow just because its a mustang? is there something about that piece of metal with a pony on it that makes cars slower. use some common sense before you go around talking trash about stuff you dont like! dont try to deny that you do this either becuase we can ALL prove you wrong. not tryin to get personal here at all.......
