This is the classic small block Chevy double hump head debate.Yes these guys are great at what they do. Website outa date,hard to navigate, etc. Could pick em apart but I have nothing but respect for them. Now let's talk modern aluminum small block Chevy head......Taylor rc. ... Obr selling "American " made "in house" products.......Turtle racing crank is in house..... Again not bashing because I don't use Obr and this is why. Taylor is all in house....... Was going to get a Obr for 5t but much research, including bartalone, left me with impressions that Taylor is more updated modern designs. Yea I have a bartalone pipe on two of my trucks because they're dam good, motor from bartalone, never....Have a Taylor in raminator, wouldn't consider anything else. Obr and bartalone are great at what they do,but old school. Taylor is modern. Old school tech is good but modern is better. Just my thoughts.
 
In my opinion, if the engine makes the amount and type of power a person wants, and its as reliable as they expect it to be, old tech vrs new tech shouldn't matter. But that's just me. I've only ran stock Zenoah engines with X cans or tuned pipes so I have no experience with any brand of aftermarket modded engines. OBR is definitely on my list if I get one. I don't need or want the most powerful or biggest engine nore am I concerned if the engine is the latest designs as long as it meets my expectations. Everyone has their own wants and that is what makes this hobby great. Lots of options for those wants.
 
Realistically neither engine is "new technology" either. 80's dirt bikes were already more advanced then either of these engines.
Having said that, There's little reason to believe the obr engine will make more power then the Taylor at any rate, port design and layout are just better in the Taylor engine. The only thing obr should have going for it, is it should be cheaper using the zen head.

The new OBR is supposed to be a 50. Unless your Taylor 35 is ported, The 35.7 Magnum which has an OBR signature series port job should be way more powerful, not to mention, when ordering the engine you can have them tweek the the engine for more torque or rpm. There's a video about it on the 35.7 thread. Almost everyone in our group runs OBR because their shop is about 15 min from us.

So this would appear to be a load of pants as I suspected.
 
I'm no expert, but to my knowledge, correct me if I'm wrong, but Taylor is an engine manufacturer just like Zenoah. There claim to fame is that they have a new design. A 35 is a 35 no matter who makes it for the most part. The .7 on the obr makes it slightly more powerful. In my own opinion this would negate any advantage the Taylor may have had. Taylor's don't come ported like the OBR does, which I think makes it a more powerful engine. This is just an opinion and I may be incorrect. If someone has more information I'm willing to learn.

By the way, Bartolone has has a 50 right now. I was in his shop a couple days ago and he was showing it to me. He's done with ddm. When they run out of his stuff that's it. He's building his own website, and it'll be on there. He said he's going to be selling them for "about" $1600. It's a BZM based engine like the ALX.

Chase volume, transfer tunnel size, port sizes, number of ports, port location are all relevant. The taylor 35 was basically ground up made for a reed case, that alone has the flow advantage over filling a piston port head, even if the obr is ported, the Taylor has more power potential once it's ported.

I fully agree !
Porting a cylinder with a less direct and more angular path , no matter what you do will ever equal a bigger design that was optimised during the disign stage . and still has not been ported (does it need to be ?) is going to produce better flow and hence more power. simply put , there is not enough metal in the Zenoah cylinder to increase the port size to the same as the Taylor V2 cylinder as it is physically wider .
So better port layout in the Taylor ported or not = more power that OBR Magnum , unless they put a custom designed cylinder on it.
 
Very well stated by everyone on this topic. Lots of good points. Bottom line for me is price,availability, are the folks knowledgeable about necessary upgrades, testing results etc. We all spend lot of money and only want the best we can afford. Good luck with the brand you choose. Thank you everyone for sharing 😊
 
hi guys!

Cheers for reply's ;) I have a Taylor V2 reed in my dibby & have to be honest, it is an improvement over my ported ESP 35 i had, but not by as much as i thought it would be, so when you factor the price/performance, imho its not worth the extra £2-300 it cost more than the esp. This is why ivve decided to go for a more powerful engine in my 5T as i defo want more power (especially torque.

Do OBR do the 47 sig series for the 5T with billet reed case option anyone know? I was also looking at the taylor 46GT, but the price difference between the Taylor & the OBR is around £400 difference! So I'm defintaly leaning towards the OBR, but not sure what the difference would be between them as i don't want to make the same mistake as i did when buying the Taylor V2 reed over the ESP thinking it would be much more power when it definately wasnt! :( ?
 
Not sure about the OBR 47 billet reed case, but I do know they answer their emails every morning if you have questions, and pretty good about answering the phone as well.

Bartolone has a 50 coming out if anyone's interested.

I made the statement before about the OBR 35.7 being more powerful than the Taylor 35, and still think it's true. The Taylor may be of a newer and better design. It has has tons of potential power, more than the OBR. But the main difference is that Taylor is an engine manufacturer, the same as Zenoah. They not selling custom engines, while OBR is. I compare it to IMO why the hobby has gotten so big. People prefer rtr rc stuff. One reason 5ive t so popular is because it comes assembled in a box, 5ive B is a kit. Same with engines. Order an OBR 35.7 and it's basically a rtr custom ported engine. Take it out the box, and install it. Done, now go run...

Now for the Taylor. Unless you know how to port, which most of us don't, including myself; where exactly do you take it? Most people wouldn't know. Then there's the $$$. You bought it, paid for shipping to get it. Have to pay for shipping to send it somewhere else. Pay for the service, then pay shipping again to get it back. That's only if you know where to send it in the first place. There's a few guys on youtube that do work.... So people are correct that a Taylor 35 has more "potential" than an OBR 35.7. But in the real world how many people are able, have the know how, have the $$$, and patience to locate and send their Taylor of to have work done. If they did, they would have an awesome engine. But how often do you hear of these people? (unless you can do it yourself or "know a guy")
 
The Taylor 35V2 in stock form will produce more power than the OBR engine due to the superior port layout in the cylinder .
Then if you have it ported it will be even further ahead.
Taylor produce engines of at least good quality to anything OBR produce and design and manufacture most of it in house , not from some other source.
Look at the Taylor vidio about ports and you will see how much bigger and smoother the layout is , just not possible on a Zenoah derived casting due to width of the transfer area , no matter how skilled you are at porting .

just had reply from OBR:

"$1149 shipped for the full mod 46cc with mounting kit and exhaust. I gave you $100 off since we still have our black friday sale up. Add $200 if you want the 47cc and porting upgrade. ... So in total around £1100, but being in UK then theres 20% VAT plus Import duties which will then take it to around £1,350+

The Taylor 46GT package with upgraded billet head is around £1570 posted. Price also includes WJ146 Big bore carb, TAYLOR BILLET HD PULL STARTER, Complete throttle linkage, V3 62mm Complete Clutch System as Standard. Seems the Taylor is better value!

Those two engines aren't even in the same world. The taylor bigbores, along with alx are in a totally different league than obr. Custom cases, heads, cylinders, etc. The obr 47 is a glorified g340, and a well built g340 will walk them all day long.

When you get into bigbore territory, such as a 40cc and above, their are only 2 or 3 names thay should ever come up in today's current production. Alx, Taylor, and Bartolone. Any Taylor or Alx bigbore will spank any obr out their in terms of everything.
 
The OBR 46/47 is a modified CY46. I think what's missing in all this is how tizdaz likes to run his rig. For example, as I understand it, most big bore engines don't have fans, that's why when you see them on youtube there always flying around a park because they need to keep moving at a certain speed to stop overheating. But what if you don't run your rig in that environment. What if you run in a smaller area where you can't run flat out all the time. What if you're the type of person who stops here and there and rig sits running? If you don't drive fast enough or stop for too long, does your engine seize, and turn into a paperweight? I don't know the answers to these questions, but since we're on the big bore subject I would like to learn something for when I'm ready to upgrade myself...
 
They arnt that fragile that a non fan cooled engine is just going to blow up when you're not at wot. To add to that, less throttle means less heat produced with the same amount of mass to dissipate the heat, ie less throttle input, means less heat input to the engine. Sure fan cooled engines are preferable, for many reasons, but truthfully there's plenty of guys that never take the covers off and don't bother to clean out the grass/mud/ junk the fans are notorious for picking up and packing into the fins.
Kinda a give and take there.
The 46/47cc engine from obr has been notorious for running hot and underperforming for years now. A search on this forum will bring up lots of complaints with them/the base engine in general. Unless they did something spectacular with the newer engines, it's not one I'd reccomend. Go grab a Taylor or ALX 40cc engine and call it a day. Truthfully fan cooked vs not isn't going to be a huge difference.
 
Mike Taylor, qoute,never had a Taylor overheat unless customer ran to lean.........part of early discussion when buying my Taylor for raminator. Very good service and as always you get what you pay for......Remember the old STP commercials....You can pay me now or you can pay me later...
