General Supercharger Thread

Hoonigan had a drag race recently of a 1000hp McClaren vs a Plaid. Plaid walked it even from a dig and the McClaren rolling.

There are so few places to let any of these ultra fast cars stretch their legs, to me it is pointless and dangerous unless its closed course. 1/4 mile racing is kinda dumb and road racing is for the rich. You want a thrill? learn to ride a motocross bike or a mountain sled.

 

"gods golf cart" hahahaha

 

Well that is where the Plaid (or any EV actually) makes a compelling argument. They all have insane 0-60 times, which is the one performance metric that you can actually enjoy on a normal road. Top speed, who gives a shit, but how fast can you get to merging speed on the interstate is totally relevant

 

"but how fast can you get to merging speed on the interstate is totally relevant"

I live for on ramps

 

I would get an EV with 100% recyclable batteries. Until that technology exists your 8 year old battery pack will end up in a landfill somewhere.

Got the tuner today, was easy to load the tune, had a question and d3 answered in 5mins.

Loaded the 93 tune and took it for a drive, first impression, it moves, will find sometime to get the vbox hooked up.

 

Alright guys, just some updates on D3's module, Dinesh has been great, he answered my 100 questions so far since earlier this year and was able to provide support via email last night.

- First gear power restriction is definitely gone, (I tried to conduct 0-100 test today to compare, the weather was similar to ones previous, in 2wd I literately spent good 1/2 second sitting sideways)
- The throttle response has improve A LOT

Overall I'm very happy with it and we are working on datalogging, he mentioned supercharger files will be ready next week.

Please note guys, I'm not affiliated or paid by D3.

 

Dumb question - can you save and restore the stock tune?

 

"- First gear power restriction is definitely gone, (I tried to conduct 0-100 test today to compare, the weather was similar to ones previous, in 2wd I literately spent good 1/2 second sitting sideways)"

I would break something if you took off the restriction. I know me.

however...clean up the shift to 2nd.

 

I’d love to learn more about D3 and their ability to remote tune supercharged trucks. The price and apparent user friendliness is definitely right, and from what I’ve heard so far his customer service and response time is pretty good. It would be great if he would join the forum so we can ask our million questions.

 

The dude that installed my S/C has a track record of awesome cars via HPTuners. Alex Pietz.

Prospeed is another tenured shop.

I would want to hear D3's track record. it seems he is just a computer dude.

I wanted my installer/tuner to have a working knowledge of engines & engine building.

being able to simply modify a map is not convincing enough.

D3 bring the info.

I'll repeat a previous post...Alex said there is a lot more in the motor, but the base tune was perfect "for a guy like me".

taking it past 6psi is possible, but I would want the tuner to tell me the foul lines before I drive it hard.

anyone can can get HP from this motor, and have no liability for leaning it out at the top when I get into it. I have to replace the motor, not the tuner.

I want a tuner that can provide me a tune that will not easily break my daily driver.

 

In the manual says you can, I had to hook it up, and choose "save stock calibration", you can return to stock file.

I don't think he's going to do remote tune supercharged trucks, last time I brought this up he mentioned he would prefer you either come to him or someone local who can use the software, best to email them.

Again, I'm not affiliated with D3, so I tried to do my homework before handing over the money, they did build a turbo engine for the new Camry, and they have had good track record on the Lexus forums, he also mentioned he had tuned the Tundra on dyno which is what his based maps are based off, and now Harrops also mention D3, that gave me some confidence.

Slight change of topic, but those of you with a Harrop especially…how frequently do you check your supercharger coolant loop and have you had to add coolant to the system since install? I have 500 miles on mine since install and on 3 occasions I’ve had to add a splash of coolant…maybe 1-2 ounces to keep it at the specified height in the reservoir which is 1” below the top or about 1/4” above the tubes in the reservoir. I always check it when cold. My mechanic who did the install did say that the bleeding method required to be used wasn’t the most effective so he did say to keep an eye on it as air bubbles may work their way out and I’ll have to add some. I’m just wondering if at some point I should be worried that the interior heat exchanger bricks have a leak as some of the early Harrop units did. The reservoir is very small so it will definitely show changes in the system capacity pretty quickly. The loop holds about 1.5 gallons total.

 

i have added a few ounces after install. I guess the bubbles burped out.

I check it when i check the oil. not had to add any since initial topoff.

I also had to add a tad regular coolant to the overfill - maybe some got out during the install?

 

Thanks for the input! Yeah most likely because part of the install is replacing the coolant crossover pipe to the Harrop one with a pulley on it. I was given the remainder of the jug for both my Toyota coolant for the engine loop and the remainder of the jug of the Ford coolant for the SC loop when I picked my truck up.

 

Why Ford coolant in SC system, why not the Toyota coolant?

 

My Magnuson was the same way for what it's worth. I think I topped off the coolant reservoir just a little maybe two times shortly after the install. Since then the fluid level has remained consistent.

 

The manual for the Harrop states to use one of two coolants, one was a Ford coolant and the other was a GM coolant. That being said I was told by both Prospeed and SDHQ that they use Toyota coolant without any issues. I actually told my mechanic to use Toyota but he is a by the book kind of guy so he tracked down the specified Ford coolant and used that.

 

Right on. Nothing wrong with going by the book.
I was just kinda wondering if there was a specific reason.

 

Something as awesome as a Harrop supercharger mounted onto a 5.7L V8 needs something to taint it. Ford coolant is the perfect ingredient.

Perfectly balanced as all things should be.

 

I'm sportin a Maggie and I would never let anyone taint her with anything that said ford or gm.
Don't care what the book said.lol

 

so stupid question but i have a 14 tundra 5.7 and all i need is their stage 1 kit with no tune and not changing the injectors? their site is confussing for a non supercharged guy

 

Not a stupid question at all. Yes Stage 1 is no tune no injectors. Stage 2 comes with larger injectors and a smaller pulley (more boost) but also requires a tune.

 

Stage 1 harrop comes with larger fuel pump,too. for non-flx-fuel rides.

easy peasy

 

Lean code update


Damn it.

well, dry frigid air has again arrived in Houston...it's 58 here.

...and as soon as i get off the highway & turn into the warehouse yard....stop in the road, put in park, to move a load timber out of the road & bam -- P0171. lean whatever.

I cleared the code & got back to life.

I think my truck is my twin & it is simply a slow learner and is averse to cold weather. I don't have a vacuum leak - or at least one I can find.

I'll give it a few days to learn, as this arctic apocalypse will be here a few days.


If I was D3 performance....I would jump into this forum & snag a few easy customers....

 

I think it might be a problem in South Dakota. 43 this morning and 15 next Wednesday.

 

that would be a problem for me & the truck.

 

I sent them a message regarding SC remote tunes specifically for stage 2. At this moment they haven’t had a stage 2 truck in there to develop a base file so nothing for me yet, but he did extend an offer! He told me to get on the forums and see if I could get someone to bring their truck in. He said if anyone with a stage 1 Harrop can bring their truck to him then he will install the stage 2 upgrades (pulley and injectors) for free, and also give a discount on the stage 2 parts. He said after that they will be developing a “stage 3 big hp kit.” So if anyone with a stage 1 Harrop is nearby his shop, there is an offer on the table for you.

 

you misspelled "Guinea pig"



I'm a stone's throw from him...I'll go by soon.

The hootennanny we had going on here has passed.
