Sirio .23 REVO Engine Mount and Manifold

[StevePond]

http://www.rccaraction.com/pics/trinity/23_revo.jpg

Sirio now offers a new engine mount and exhaust manifold to install the ultra-powerful Sirio .23 engine in the Traxxas Revo. The new mount replaces the center section of the stock 2-piece engine mount, making the installation of the wider .23 engine a bolt-in operation. The exhaust header adapts the big block exhaust port of the Sirio .23 to the stock and most optional tuned pipes. The exhaust manifold also fits standard big-block engines, so it's going to be available separately for those that want a larger diameter high-performance manifold when using the Traxxas and other big block conversion kits.

Part no. TRI42028

Suggested retail price: $55
Price for exhaust manifold only $29.99

Wow. There are alot of engine kits coming out for the revo. I wonder why this never happened for the T-maxx. I guess companies learned there lesson.....

[StevePond]

The engine for which this mount is made was originally designed for the T-Maxx. This "happened" to a far greater extent with the T-Maxx that any other vehicle in the history of RC. I don't know what planet you've been on ;) but there's a ton of engines that were developed just for the T-Maxx.

Sirio .23
Sirio .18
Fantom FR18
Picco P2 .21
Omega .21
OFNA .21

I'm sure there are more that I'm missing, but hopefully that makes the point.

Cant forget the OS .18 TM

So, will the EZ-Start stay with this setup?

Well didn't most of them come out recently? Sorry, I didn't mean to offend the gods of rc :( . I was just looking at the amount that have come out this soon for the Revo compared to the T-maxx. I know that motors have been coming out for the t-maxx "recently", but a couple weeks after its release it didn't have this many(i think, cant remember that far). I am sorry that I didn't specify this in my original post.

You're right. When the T-Maxx came out next to nobody came out w/ bolt-in engine conversions for it like they have for the Revo. There's a reason for that though. Now that Traxxas has proven they can sell nitro monsters, and a lot of them at that, so companies aren't nearly as afraid to invest money in a product for the vehicle because the know it's very very likely to be a huge success. Just like it's really hard to buy a car when you have no credit, but after you've established credit it's easy. Precedence (sp?) makes all the difference in the world. It's a risk factor. Companies know that Revo's are gonna fly off the shelves, so obviously there's a market for upgraded engines (especially since Traxxas still included a small block). Companies didn't know that T-Maxxes were gonna sell...and by the time they figured it out, and then developed products for it, it had been out for a while.

Don't forget that with the T-maxx you had to either drill out the stock chassis to accept a different motor mount or you needed to buy a different chassis. With the revo you just need a different motor mount since it uses this new fandangled swing design. Traxxas did do their homework but to bad it was homework to find out how they can make more money off the people that buy their products.

Revo drivetrain is still all plastic now spend the money on the .23 and then the motor mount and then the exhaust manifold. And then watch all the stock drivetrain parts go POOF. It happended with the orginal and it is happening with the revo but that is traxxas, if you want power you need alloy drivetrain that has been proven over and over again.

Plastic+Power= More Money spent in the long run. You should have just bought a Savage/MGT/LST right off the line and been set but some people are well MOOOOOOO!!!

[rckid11]

Thanks for the support. Yeh its kinda weird that they are releasing such overpowered engines for the revo. The revo is mainly meant for a light well powered monster truck, not a brutily overpowered one (savage, lst, genesis, ect.)

[StevePond]

I know that motors have been coming out for the t-maxx "recently", but a couple weeks after its release it didn't have this many(i think, cant remember that far).

I'll just say this and then hopefully get this thread back on topic... There was no need for special engines for the original T-Maxx because just about any side exhaust small block would fit, and most aftermarket engines were much more powerful than the TRX .15. So there were crazy engines (relatively speaking) for the original T-Maxx, but they were the same engines that you could install in just about anything else. Then came the 2.5 T-Maxx. Engines that were developed for this needed to be built from scratch. They had to design and develop entirely new engines with the Traxxas specification on the crankshaft and to adapt to the new bolt-on exhaust flange of the TRX 2.5 engine. That takes some time and that's why you didn't see many of the T-Maxx specific aftermarket engines until the 2.5 had been out for about a year. It's probabaly the first time that engines were ever made, certain in the quantity that are available, for any single vehicle.

How can they make them so quickly for the Revo? They're already here. They're the same engines that were developed for the T-Maxx with the possible addition of a tweak here or there to make it fit, or a new mount - a mere blick of an eye compared to the time it takes to develop a whole engine. So it's simply a matter if having already laid the groundwork that made it so easy for engine makers to put these mills into a Revo. Had they not first developed them for the T-Maxx, you wouldn't be seeing any of this for about another year.

Jack, you have real Traxxas issues that you need to resolve. ;)

[Jackyl]

:) Steve, don't get me started on traxxas :mad: This thread is about an engine mount and a header sorry if I swayed in my original post.

I hope that anyone that puts a bigger engine in their revo has good luck with it because I wouldn't wish bad luck on anyone especially since they are already in for it since they bought a traxxas "sorry steve :D" J/k

I'm waiting for the day to see a decked out race revo at the track so that I can have a firm basis on what I bash :D


Hey Steve,
You know once you go hybrid everything else is... well in efforts to find a better word *Blah* :o It's just something about the way certain vehicles put the power to ground some are fun some are ok and some are ungodly! you know what I'm saying steve you have to ! but being the unbias man that you are "because of finacial obligations" I understand if you can't say anything on either front.

But this looks like a sweet setup. But it's got a trinity name on it so the price is high 30bucks for a manifold? Wait!

Do you really need anything more than a high rpm .18 ? ? people it's called gears change em'

It's all good though, if your building a revo MoNsTeR then you have to have it so buy it

[txquad]

How do I overcome the air filter problem with the new Picco P2? I have the new motor installed with the newera mount but now the carb is so close to the spur gear that the air filter will not fit on. Is there something I've done wrong or is there a new filter I need to buy. I'm DYING to try it but obviously I cant without it.

Umm...not. :rolleyes: I've had several gallons through a P2 in my Revo, and the drivetrain has held up fine, thank you. No twisted driveshafts or broken universals, and the diff gears are still good.

Well I think you should take a better look at what your knocking. The Revo is being proven to hold up under some heavy loads without breaking.. I saw a guy with a .27 straped in one and hasent had any of the drivetrain fail.
Mind you I'm not a big fan of Traxxas but these things are holding there own on and off the track..

[Chris LaPanse]

Yes - their diffs are far stronger than the maxxes (which are the ones that go poof - even stock)

[Assault23]

My brother put a wasp .28 on his revo 7 months ago and hasnt had no problems.I own 2 revo's with no major mods im going to put a sirio .23 on it couse the wasp is really powerful it flips backwards when it hit 2 gear to mutch for me.

[Assault23]

The reason people be breaking drivtrain parts is couse yall have your slipper clutch to tight if u put a big block on it you got to have it to where it will slip right off the start if it does wheelies then its to tight,wheelies are fun to do but not all the time.
