Watt-Man Thermobob vs. MCP Thermal Control System

Seems like these both do the same thing. Without mentioning Watt-Man's specifically, MCP says in their description "Works much better than similar options". Anyone have any knowledge of any differences between the two?

Yeah and his carb kit says you get more hp, torque and mpg!
Watt man is the way to go!
Creative marketing?

Overlooking the claims MCP’s products do work. Is one better than the other is up to an individual to decide. I don’t think anyone is going to buy both Wattman’s and MCP’s products and do a side by side comparison. The results will be basically the same. I would base my final decision on the hit to my wallet to get it in my hands.

As far as the cooling system mods go, I believe (going off memory) the biggest difference is that Watt-Man uses a higher temp stat and that makes sense to me....functionally, I'm not aware of any other difference.

2 cents,
Dave

Thanks for the input y'all. It does indeed seem like they do the exact same thing. MCP also uses a blue hose and brass connectors so I think I'll be going with the TB2 as they have gunmetal/hammertone connectors and a black hose to better match the bike and not look like some DIY hardware store parts.

Might as well think on it a while if your ordering from watt man. He is out for a few days. Won't ship until 5th at least

I put up a post (I thought), reflecting on MCP's claims, but . . . must have fumbled posting . . . the post ain't here! Regardless, of no consequence.

Now, take the PCV mod, oh, never mind! Had a share of, optimistic operational performance claims and True Believers, as well! :)
Check rockymountainatv. They sell the TB2.

I know you might've been making satire but someone might've saw it as a real MCP advert 🤭

Good point!

In my view, satire (and, send-up, irony, farce, etc.) plays to mixed reviews on motorcycle forums! Some take the comedic device quite literally.

Maybe, MCP is a paying member of the forum vendors. Wouldn't want to offend any of those, or of any prospective vendors.

Well hey what do you do, it's not always easy to convey subtle humor over text. Like you said it can often get taken the wrong way

I also believe that I've previously read that the MCP product supplies only a 185F thermostat. Which seems strange, being that the builder lives in quite a bit cooler climate & modern engineering has proven over the past 70-80 years that 195-220F is better for IC Engines overall. Probably a matter of 'sourcing' the 195F thermostats in Canada.

Other than that, for Canadians they won't have to pay an Importation Fee to their Customs Office which they would have to, to acquire a genuine Thermo-Bob with the better 195F thermostat from any USA supplier.
I do not know whether or not a USA customer would have to pay an Importation Fee to US Customs if purchasing the MCP kit from the Canadian builder.

With either system, the cooling fan is still only going to operate when the Bottom of the radiator (fan switch) reaches between 205-215F, even though the cylinder head will read higher (temp gauge sender or temp light switch location).

Looking on the MCP website at the thermal control system it does not appear to come with a thermostat.
From MCP on Facebook (I asked what his does differently) "isolates the radiator better from the engine keeping the rad cooler, and keeps the WHOLE engine/thermostat temp better including the bottom end. This Preserves Maximum cooling capability of the system, other mods reduce maximum cooling capability." He says he recommends his if your guage drops below normal operating temp during increased RPM or increased road speed.

Not that I really understand how any of this works. Just passing the info along.

I'm also seeing ProCycle has their own version of a Thermobob too. Looks like the same thing.

Without the motivation of selling a latter-day Thermo-Bob copy of my own, seems to me, after the thermostat opens, engine cooling is at the mercy of air flow and coolant circulation alone, regardless of any bypass.

Despite MCP's eloquent praise, the mechanics of, "Preserv[ing] Maximum cooling capability," claimed, without evidence and explanation, eludes me. Also the premise, "other mods reduce maximum cooling capability," remains hard to swallow, without some explanation and data.

To the best of my knowledge and belief, enhancing maximum cooling capacity has never been claimed by Thermo-Bob.

If MCP has indeed invented a, "better mouse trap," then the world surely will beat a path to its door.

Or not🤣

Claims like this is why the man responsible for them has been suspended or banned from this forum 3 times to the best of my memory.

Any cold coolant radiator bypass is better than none.
But to claim that his "Preserves Maximum cooling capability" is totally bogus sales hype and impossible.
Purposely allowing an IC Engine to operate below its most efficient operating temperature is detrimental to the engine oil, therefore detrimental to the Entire engine.
Therefore barely better than the non-bypass system that the factory supplies the KLR with.
IMO!

I'm glad you pointed this out and not the only one who figured the same thing. Isn't the thermobob supposed to raise engine temp/keep it at the optimal temp so as to remove temp swings and eliminate ovular bore wear, not lower the temp? Seeing him say "other mods reduce cooling while mine maximizes it" makes me think he is missing the point behind a thermostat mod.

I asked him this specifically over Facebook "TB2 intentionally raises/sustains temp to remove damaging temp swings. Is your kit simply allowing these temp swings to stay in place or simply keeping the bike cooler overall at a steady temperature?" and he said there's nothing intentional about the raised temp of a thermobob and it's actually a design flaw and that other thermo mods don't work properly because "they were made on machines that don't make heat properly" (whatever the heck that means lol. If he's referring to stock he'd be right but not for TB2 which was the topic of discussion). He actually says the temp swings are normal, expected and harmless. Hmmm 🤔 don't think so.

I think hearing him say this pretty much settles any debate over the TB2 vs. MCP TCS.

I’ve stated before that if your climate never goes below 70ish F, then maybe it’s not as important. But in North America I wouldn’t want to go without it. Heck, in 8 more years (according to “them “) the planet will burst into flames anyway due to global warming🤣🤣. You won’t need a thermo Bob then!!!
