Model Forum / Radio Controlled / Land Models / March 2007big-block for Revo?
I'd like to hear the pros & cons of installing a big-block in a stock Revo. Anyone have any first-hand experience? I know someone who really wants to install one, but I'm afraid it will lead to reliability problems (ie: stripped gears, broken drivetrain, etc.). Please provide exact engine make/model if possible. Thanks! Scott -- Has Western Civilization become "too civilized" to defend itself from extinction? >I'd like to hear the pros & cons of installing a big-block >in a stock Revo.

Come complete with a mount, header and pipe (and the engine). My kid has a revo with an RB 323, and it works great. The entire package can be had new for around $240.00 USD, (I recently found the same thing, NIB, only for a T-Maxx for $160 on ebay). They also make a 523 that is newer and more powerful, and of course more expensive. These are both .23 sized engines. Otherwise, I've read about others complaining about big-blocks tearing up parts, but people do the same thing with stock motors also, , so I question how much of the problem is power. So far no problems with the kid's 323, but it's not been run too much after breakin. No broken drivetrain parts or such. >>I'd like to hear the pros & cons of installing a big-block >>in a stock Revo. Anyone have any first-hand experience?

Like GTD, I too have the RB TM323 and it is a fantastic motor, it gives the power to wheelie every where, and use longer gearing, and doesn't up the weight noticeably. They give really, more power than the Revo needs and are brilliant engines. > Otherwise, I've read about others complaining about big-blocks tearing > up parts, but people do the same thing with stock motors also, , so I > question how much of the problem is power.

My 323 hasn't damaged my Revo yet, but on the forum I use it's generally the consensus that big block in the Revo will kill the diffs and transmission. How long this takes depends on driving style and the big block you choose of course :-)  SignatureDan Formerly DanTXD > >>I'd like to hear the pros & cons of installing a big-block > >>in a stock Revo.

Also, keep in mind that some of the BB motors that will work with the BB kit (not all do), end up, after a pipe and all, being more expensive and harder to fit (some need you to modify or replace suspension parts, some may require a bumb starter), yet yeild little or no improvement over RBs drop-in engines. >"Iridium" >"GTD" Thanks for the info...I thought the stock drivetrain might be in danger from a "decent" big-block engine.<G> My friend decided to buy the O.S. 18TM instead of the RB323 setup. I don't know too much about the engine except it's the $150 "regular" version of the .18TM. Anything pro or con to say about the .18TM?

They have a great rep for use in the Revo, and OS engines are good :-) SignatureDan Formerly DanTXD > >"Iridium" >>"GTD" [quoted text clipped - 8 lines] > > Scott My bud has one (OS .18) in his T-Maxx. It SCREAMS. Holds a tune like you wouldn't believe, will idle all day without loading up, runs consistently cool and has gobs of torque and top end. Of all the engines I've run or helped to tune, this one takes the cake. If I owned any smallblock powered trucks they'd all have this engine in them. Doc >>"Iridium" >>"GTD" [quoted text clipped - 12 lines] > Has Western Civilization become "too civilized" to > defend itself from extinction? What's wrong with the 3.3? That thing rips and is easily comparible to the .18tm. If you know how to tune. I always hear "the .18 holds a tune so much better"... maybe it's because it's more forgiving. :) I've run my 3.3s from 70 to 40 without touching them. Sure, I smoked my first 3.3 at 1.5 gallons.. but I attribute that to learning how to tune these little suckers (even after years of 2 and 4 stroke tuning). Now on my 2nd 3.3 I've got over 8 gallons in one (and still running strong, even after a runnaway where it was up a tree, wheels off the ground at WOT for at least 30 seconds, header glowing red), 2 in another (both TMaxxes) and another in a Jato that's just waiting to be broken in. :) And for 1/2 the money, you can't beat it. :) |
