Magnuson vs. Harrop vs. Whipple - Supercharger showdown

It should, but like any performance mod/vehicle you need to pay more attention to things. A normal supercharger installation shouldn't need anything extra, but if you choose to ignore things like your gauges or listening to the engine then it's more likely to bite you in the ass if something goes wrong. Same thing applies to a stock truck, if you aren't paying attention and something happens it'll grenade, but it's much more imperative to pay attention with something that has more horsepower thrown at it especially if you're pushing a bolt on modification further with custom stuff like pulleys and tuning past what the stock supercharger includes.

With that said, lots of people that know nothing have performance vehicles and they run just fine, and lots of people with supercharged Tundras with no gauges, no installation experience, and no knowledge of a supercharger besides high octane makes the truck go faster. So it's your call, but I wouldn't be scared by it all, just a bit of research and extra vigilance will go a long way in the rare case something does happen; for any stock supercharger/tune you shouldn't ever have an issue though.

 

You deconvinced me. Well done. Lol. A bit of research, extra vigilance & paying attention I can do.

 

Don't need to know about PSI / Tuning / Fuel Mixture blah blah blah. Once tuned, either with a custom tune or using a proven canned tune you are " good to go " Just understand you have modified your truck beyond factory parameters.

Floor it on a stock cold engine might make it run rough, floor it on a supercharged ( original N/A engine ) might throw a rod.
Lose fuel pressure at WOT on a stock engine might make it knock and pull lots of timing, lost fuel pressure on a supercharged 3UR-FE WOT might ( will probably ) throw a rod.

Just have to know there are inherent risks and be vigilant if you here/see/feel something is wrong.

 

Two things I had no clue about. You’re kinda convincing me again that a supercharge ignoramus like me shouldn’t get one. My eyes bugged out when I read flooring it on a cold supercharged engine might throw a rod.

 

The gist of my statement is : if supercharged, make sure you are up to temperature ( oil, coolant, atf ) and engine is running fine before you beat on it. Anytime you mod your engine for more power, the risk of engine damage increases ( when something goes wrong ), does not matter if it's headers, tune ( N/A ) , nitrous, supercharged etc. Any problems while beating on the engine just has the potential to be "bigger " the more power you have added. But to allay your worries/fears, I have a TRD Supercharged 2UZFE with 280k miles ( 250k supercharged ) and a TRD Supercharged 3URFE with 160k mikes ( 90k supercharged )... both run fine, I just make sure the engine is up to temperature and everything it working fine before I beat on it, both are factory TRD tuned. Install your supercharger and enjoy it

 

Roger thanks for the info.

 

All of the Whipple fs postings I see say no Flex applications. Anyone know if that is a hardware issue? I have flex tuned out on a HP tune & the high pressure pump relay removed.

 

I’m guessing they just mean the tune that they provide with the kit is not capable of being used on FFVs. Otherwise i don’t think it would be different than the other brands hardware wise. Also FWIW to respond to the original thread inquiry, the Whipple’s best features are its price and the whine it makes IMO. I’d buy the Magnuson or the Harrop over the Whipple for what appears to be a better torque curve (with the larger pulleys at least).

 

Has anyone installed the Whipple?

 

Whipple website is pushing for non-street applications, so that seems off the table for a daily driver.

Most people talk about owning a Magnuson and heck, even in Montana the Toyota dealer will install one on a 2020 Tundra (non-TRD supplied year). However, if you watch the videos and see how the Harrop works and is built, it just looks much more refined. The Harrop air temps are lower, the airflow looks logically much better, it produces more power with less psi, the Magnuson o-ring scenario or hard to reach bolts dont exist,... but still, not as many people go that route, from what I read. Add to that, I reached out to Harrop over email and got a reply in less than an hour. But, there are like 12 distributors of Harrop in the US and 100+ Magnuson.

Am I missing something about why most people go with Magnuson?

 

Usually the Mag can be bought cheaper than the Harrop. People also buy it because there are more of these chargers installed under TRD name and subsequently Magnuson, more installers available, viewed it as a more proven upgrade, etc.

 

Agreed with Zphilip on the definite appeal to many on the fact that it was good enough for Toyota to brand as TRD so it must uphold Toyotas quality standards. It also has an appealing warranty if installed on a truck within the first 3 years and 36k miles. The magnuson is probably the most friendly to the install it and forget it type of user. The Harrop and Whipple have a definite appeal to those who like to tinker. All can make plenty of power with some additional mods to break stuff though. I ultimately chose the Harrop for a lot of the reasons you mentioned.

 

@Tundra John has a Harrop he installed himself. Sure looks good under his hood and he mentioned zero regrets.

 

Mag & Harrop perform about the same in real world applications.

The Harrop has better tech & engineering, but that does not seem to translate to installs that stay around 575WHP.

Mag has the TRD legacy behind it.

and Harrop looks better under the hood. The mag looks like you have an armadillo sleeping under the hood.

and, as of a year ago, they were priced about the same. "about"

 

Ok. As expected. Certainly a solid point, "Toyota to brand as TRD so it must uphold Toyotas quality standards". But, sure hard to look past the tech and looks of the Harrop.

Thanks all.

 

Did anyone ever get a wipple sc. I’m wanting to head towards that one of the three and was curious about stats. Also if I’d have to get it dyno tuned or if I could use my bullydog

 

Yep I’ve had one along with my old man and a few others on the forum. I moved from a magnuson 1.9 the difference was significant. You should absolutely get it tuned as the tunes included aren’t that optimized. These trucks need a richer tune to be safe. Power wise mines modded further than what’s included in the original kit. I’d venture to guess 720+hp crank.

If you want one @memario1214 can assist there

 

Will you let me see where you have your gauges installed? And how much does it cost for the dyno tune?

 

I just did the Magnie 2650 and loving it.

 

I have the craven speed mount and aem gauges. Mine was road tuned and data logged. Which is very common
