General Supercharger Thread.

Sounds encouraging! Fingers crossed and hoping it’s fixed!

 

What you are saying is, there's not a lot of point in going with the Harrop stage 2 unless you are willing to start upgrading the internals and more.
Stage 1 + tune and call it a day. (the vehicle is a 2017)

 

Stage 1, press tow haul button. Laugh your ass off at the difference. Even with my "anomaly" of a bad pcv valve, the performance at stage 1 makes the Tundra a very different truck. Even if someone finally cracks the eco codes on 2019+, I don't think I'm interested in the extra hassle of "tuning" either but that's just me.

 

I'll concur...if tuning is not avail, Stage 1 meets the needs. Its hard for me to imagin it getting much meaner without tearing shit up in the drivetrain.

However.....Dyno said I had 435 to the tires....I'd like 500 to the tires. I reckon Stage 2 would get me there.


the "i do cars" youtube channel has a teardown of a 3UR...interesting stuff.

 

Thats great news. Please keep us posted. Has someone looked at the failed valve?

I didn't mean to imply that if that is how the post read. From what I've read here you can safely get to 550 without new internals. I haven't looked at the Stage 2 kit recently but from what I remember its mainly a larger pulley and requires a tune, perhaps @Puba can comment on any additional items the kit carries.

 

Are you saying 550 at the crank or 550 at the wheels with the stock internals?

 

Crank. All the horsepower claims from the supercharger manufacturers is crank hp, and from my research once you go over 600 at the crank the bottom isn't happy. The magnuson claims 550 crank with the stock blower iirc.

 

Forgive me if this is a stupid question or has already been covered, but is there a main difference or reason to go with Harrop over Magnuson? Only reason I ask is because my Toyota dealer is an actual Magnuson dealer and it would be "nice" to have it done by them...but the Harrop needs to be done by a shop that is over 75 miles away from my house. Not the hugest deal, obviously I'd rather go with the better product and not get hung up on who's installing it...and how far they are away from me geographically. Thanks guys!

 

@ViktorG did a(n intercooler) comparison video here, make sure you read the comments in the video as well:

The Maggie is the same as the old TRD Supercharger Toyota offered but discontinued. The warranty is better with the Maggie, they offer 3 years or 36K Miles. The Maggie is easier to maintain and doesn't require removal to change the oil. In your case its likely that the Toyota install will preserve the Toyota warranty as well, they won't flag you in the system if you take it in to get other services done.

Harrop has larger volume and will let you push the engine to a higher top end. The inter-cooler is larger on the Harrop as well.

 

That's what I figured, but got my hopes up for a moment that I could safely push it a bit further. I was holding out for the Viktor tune, but now will have to see what other options I have...

 

Whipple is the third supercharger option but I've not seen too many talk about it here; there was thread discussing it but I think there were some delivery or manufacturing issues that delayed the install.

 

All the failures (that I remember at least) reading about were people that routinely went to the drag strip and were really winding the engine out. It's not a cut and dry "your engine will fail within xxx miles at xxx horsepower". I think for most people if you had 700hp, and your extent was racing someone at a stop light and merging on the highway where the engine sees a blip of very high load but it's not prolonged then I think the engine would potentially last forever. But the people that tend to really push the horsepower are also the ones that tend to go racing, so all the reports of engine failures from high horsepower just happen to be people that are really beating on their trucks, I think there's a correlation not a causation... but I may be totally wrong and the bottom end just plain can't handle over 600hp in general regardless if it's for a short duration or not.

 

600 seems to be the trouble spot which is why most precanned tunes keep it at 550 or below before requiring new internals, again this is from reading the forums. I haven't seen an official number listed.

According to Harrop the engine is "Capable of over 1000hp+ with supporting engine modifications" but they don't say what that point requiring mods is. Stage 2 puts you around 550.

To answer Saltyhero13, the Harrop stage 2 has larger pulley plus a full set of high flow injectors. Requires tune. Can do on some 2019s but for the most part, 2019+ no bueno on the tune. If you have a shop with HP tuner, they can tell you in less than 5 minutes if a 2019 can go stage 2. I was hard pressed to find anyone around my locale that did, but when I did, the answer was no for me.

 

You gentlemen who may be on the fence for the Harrop, I'm getting the slightest bit of pressure release at the dipstick still.....I'm just driving around town this last week and check it every time I stop and get out. No spikes on the dash oil pressure gauge. I asked Chris at Harrop about add on methods to provide a little more breathing, maybe even a catch can down the road....he said some people do that but according to Harrop, not necessary at stage 1.
Anyways, I have an appointment for compression testing on October 5 at a real speed shop near my work and I'll try and get a post up after I get the results. These guys won't do the deep down engine work but I asked them to check everything up top for the helluva it.

 

I wonder how our supercharged tundras will stack up against the Iforce Max for 0-60 times? The new engine has some more torque than the Harrop and maybe lighter too so it could be a close race!

 

The old timers always told me,"there's no replacement for displacement"

 

i think it will be pretty close, 3rd gen hybrid sounds impressive

 

A new transmission also helps.

 

I had a 2011 3.5 F150 eco boost (damn near same specs) before I dumped it and went for my Tundra. I hope Toyota has better luck, I mean, the people who buy the new Tundra than I did. I would probably wait a few years before I jumped in that's for sure.

 

I'm having a heck of a time getting a call back or quote from either of the 2 shops Harrop recommended to do the install in my area. I may have to go Maggie at the dealership if these Harrop dealers don't get back to me, as I assume Harrop isn't going to sell to me direct and allow me to install it.

 

I bet all of the installers are backed up. Out here in California just getting a response could be a couple weeks. You can have Harrop ship directly to you also if warranty coverage isn’t necessary for you. Only Harrop installers give a warranty I believe.

 

I believe you are able to buy from them direct and install it yourself. A handful of Harrop dealers around me don't work on Toyota's. I contemplated on making the drive out to Harrop in Ohio to have them install it. But weighing all the costs and I'm having a hard time commiting about $10k with install.

 

You and me both! I mean, I’m totally capable…hell I built race car engines in pops garage growing up. I’m just getting older now and leaning over an engine bay sucks ha! Especially for 8-10 or even 12 hours.

 

@rocky_mtn_trd are you planning on going over 550HP?

If the Toyota dealer install doesn't void your manufacturer warranty and Magnuson provides you their 3year/36K Miles warranty I would go with the Maggie. My only gripe is you have to use OVs Tuner on the 2019s; not sure HP Tuners cracked the 2019+s yet.

 

I don’t really plan on pushing it past 550. I’m waiting for so many things right now…coachbuilder TRD Pro lift, tires, truck cap, bedrug, head units to be back in stock…but I digress. I’m mainly waiting on these folks that Harrop recommended to get me numbers and start the dialog. But, I’m also waiting on the “accessories service writer” at the dealer to get back to me so I can discuss factory warranty questions with him if I go Maggie. I don’t really plan on ever going stage 2, I say that, but I also never planned on trading in my 2017 SR5 for a 2019 TRD Pro let alone getting a blower fitted. I don’t ever really see myself stroking it so I’m torn on if I want the bigger Harrop blower or not. I mean, I want it…we’ll see. Stay tuned haha

 

When I had mine installed, I remember that the warranty was good as long as you had an ASE certified shop do the install.....there is no such thing as a Harrop dealer near me. I double checked to be sure with Chris at Harrop Ohio. I ordered my supercharger on line and it shipped from a company in Arizona that had one left..... direct to my house in Pennsylvania. The ASE shop that services all of our company work trucks did the install. Harrop 2650 were all on back order at the time. Couldn't get one direct. The shop had my truck for three days.

 

No advantage of one over the other if you stay Stage 1. Someone will correct me if I am mistaken.

 

Harrop seems to be better engineered. bigger blower turning slower for the same 6psi. less intake heat.

also the Intercooler is better engineered - one on each intake bank. again, less heat.

all this for a marginal price diff.

I think a S/C tundra (stage 1) would win against Std 3rd gen tundra. The Imax would be close, as the electric motor will simulate the instant boost of positive displacement blower. I'll say S/C would win by half a car length.

I will volunteer the 2020 if fed a complimentary meal.

lean codes chapter 3.

in line at chick fil a...93 degrees outside....i'm waiting in line...put it in neutral...15 seconds pass...bing...P0171 & P0174. lean whatever. no sweat, I cleared the codes and motored on. I guess it popped a code when the a/c compressor kicked in being in neutral. for the high strung folks - this is nothing major. it's just a code & a bunch of (Trailering pkg)lights on dash. reset codes with your OBD thang. the lights will clear when you restart engine. this does not induce limp mode. for the record - I have never popped a code under load. after ruminating on this, I surmise that when the A/C comp kicked on, it aggravated the boost bypass (see chapter 1) and pushed too much air into engine. as the boost bypass sensed mass air pressure diff between front and back of blower. regardless of what the ECU thinks.

Have great weekend.

 

Question for the blown hive.

if you have a blower, have you upgraded your exhaust?

just had a poo-bah meeting here at the office. during small talk, we discussed my blower. ok, break for lunch...I ask "who's riding with me?" 6 GROWN-ASS men raised their hand. then we figured who would ride with me there & who would ride with me back.

Grown ass men.

yes, the Tundra will light 'em up with 4 >200lb men in the truck.

life is good.
