Are these any good? i read that they just kill your motor a whole heck of alot quicker

they look at sound cool, but i dont think that they do a whole lot for performance, and u can say "my trucks got a blower" and the other guy will be like "o yeah well my truck looks cool" sorry im bored

save ur money for a faster motor lol its not worth using those just more stuff to break

i agree save ur money

There are claims that they work, and claims that they don't. I have never seen one dynoed. I say save your cash and get a nicer motor...

ya I was just getting opinions, thanks

They might give a little power on paper but after you factor in the weight and RPM loss form having to spin a blower off the engines crank it would not be worth it. Just like the RC nitrous systems. All the Nitrous is really doing is leaning out the engine for an extra 15% HP but after you add in the weight of the system its totally not worth it.

Ditto!

The only way it would actually work is if you could also increase fuel flow in proportion to the additional nitrous.

Same with the blower...extra fuel along with the air and compressing it so that you actually got boost...then it would work.

so we need to run a fuel pump off of the super charger... uh huh. (Ok that would never work lmao)

You'd have a better chance w/ the nitrous...to get it to work you would have to richen it up, then spray it. It would really only run killer when "on the juice"
Keep it tuned to run good on it's own...spray it and it's super lean. (engine killer)
That's why nitrous kits have both fuel solenoids and nitrous solenoids.

another thing I see with the Forced induction on our engines is both the intake and exhaust ports are open at the same time for a good portion of the engines revolution and our engines use the pulse comming back through the pipe to force a/s mixture that seeps out of the exhaust port back into the combustion chamber. If you have air forcing itself into the engine Its got to screw up the return pulse.

Nitrous would work better. but still there is the weight of the Nitrous kit and would IMO negate any HP gain you would get from Nitrous. NX makes a nitrous kit for our cars and it fricken uses a 1:1 car solenoid which is like adding the weight of another .21 to an RC. it would be better to spend the $100+ dollars for a N2O kit or blower for our Rc's and put that towards a better engine.


Man it would be nice to get an A/F ratio monitor on our cars! That would be able to tell 100% that the Blower/turbo or nitrous kits are only seeing any power gains because they are leaning out the engine a bunch rather than actually burning more fuel during combustion to make more power.

Very good point. 2 stroke engines do not use the same principals that 4 stroke engines would. Cam timing issues such as overlap and duration play big factors in how nitrous or forced induction produce power.

You're better off using the money and getting an engine modded for more power.

hey six i wonder if a wide spek o2 sensor could tell the diff? like the kind they stick in your exhaust when your running on a dyno? might work?

I don't think nitro fuel exhaust is hot enough to make a conventional O2 sensor work. maybe if it was REALLY high nitro content, like 70% or so.

That my friend is why you get a h.e.g.o.! It is heated up by electrical coils on the inside so your exhaust could be ice but it will still work. And since your new(and one of dans friends) have you ever grabbed an exhaust pipe after a run? They can be extremely hot! (dan you can start the jokes now hehe 400 degrees!)

btw j/k thubbed one!

LMAO... this guys buggy died today... after he walked back to the pits with it through the 45* or so track I still temped it at 407*!!! I think he beat you. LoL

Holy chit!! Thanks for the little pick me up dan! doesn't make me feel to bad about my tuning abilities! Since woodridge i've run my buggy a few times and the temps haven't even hit 250 I think that book helped alot! Doesn't help when the motor is toast though!

Yeah... I had my idle a little lean so when it sat there warming up it really warmed up once. I think I tapped 300*. After I richened the low speed a tad I was running very well between 220 and 250. Good day at the track. (Besides the poor qualifying and almost missing the start of the main due to blown plugs...
