General Supercharger Thread

Is it me, or Does that make 38’s sound less cool? Lol

 

Just imagine the people with stock trucks who have nearly a 15% power loss, especially if you aren't geared. Sounds slow af

 

It can’t be very stimulating

 

I just put a 200lb. Cap on my bed and I’m thinking it feels slower. Can’t imagine having that much extra rotating mass.

 

It’s kind of like body dysmorphia but with our trucks lol

 

I didn't particularly care for that set up I was more interested in the vehicle performance before and after the mods.

 

It would be kind of cool if Toyota let you choose different gears if you build a tundra. Ford and dodge will let you do it but I don’t think Toyota does. Atleast have one other option would be nice, if you know you’ll go with larger tires

 

yup.

I'll 2nd @snivilous on the Stock truck on big tires....normal driving must feel like you are towing a Mastercraft X26.

Pardon me for bringing this up in a Blower thread -
one of the more mathematically inclined hombre's around here could probably pull a MPG/efficiency loss from those figgers as well. If one were so inclined.

 

At one point the host takes it on a drive and claims he is getting 11.8MPG (7:25 mins) and in the comments he says he is getting 11.5 MPG hand calculated with the 529 regear.

 

so...a stock truck gets ~15? big tires get ~12? seems right, as has been hashed in 4,253 threads so far.

I wonder if his 11.8 is because the blower is into boost more than a stock truck just to get the unsprung weight moving. or, said differently, the driver simply having the ability to push the skinny pedal & make the truck move a LOT faster than stock.

Extended city driving gets me down to 14mpg.


now that I have a few 1000 miles on the stage 2....if I stay out of open loop/PE, my mileage* calculates very accurately on the scanguage II. However, once you open it up, it appears the larger injectors completely wreck the calculation algorithms. on-ramps & passing cars are quite enjoyable.



*the dash MPG is hosed...it says I get 27.5 mpg. and a full tank has a range of 715 miles. Hello Elon!

 

good to see consistency on these Harrop installs. here is a stage 1 tuned. dyno @ 4:10

I have a theory on the MPG readout. I think the scangauge would ordinarily track mileage fairly accurately once you calibrate through the “fillup” procedure despite the larger injectors. I think the reason it becomes less accurate when you do more WOT is because our Harrop setups are using boost referenced fuel pressure regulators. Out of boost it maintains a pretty steady 43ish PSI, but under boost it jumps up to more like 50. That is something the computer can’t really measure and it still thinks we are running at a constant 43psi, and therefore skews fuel flow rate and MPG readout.

 

That is who I used. Inquiring about their Stage 3 offering.

• Harrop Engineering TVS2650 supercharger system
• OEM Lexus RC F 84mm throttle body
• Prospeed Autosports 4.50" air-intake system
• ZPE GripTec 80mm supercharger pulley
• DeatschWerks 650cc/min fuel injectors
• Harrop Engineering high-flow fuel pump
• NGK LFR6AIX-11 spark plugs
• Genuine OEM Toyota coolant
• Custom Calibration via HP Tuners or VF Tuner
• Optional:

That's almost my identical install minus the RCF throttle body. I wonder if I should have done that.

In his setup he say 1 PSI from enlarging the 76mm to 84mm.
Part is plug in minus the tuning:

@Saltyhero13

same here. <still eyeballing the 4.5")

I am intrigued. Ya think this would get you ~500-510whp? @nags - what did you dyno at?

if you can get an extra 1 psi & "safely stay on A MAF map" I'm all over it.




I see that's the TB for the 5.0L....sexy.


Giddy up, Salty.

 

Teslas are so cute.....

 

very, very cute.

my video proves the 918 walks the tesla mechanically( and sounds 1,000,000 times better)

you gave me a video of a crappy driver evidently....

 

top speed, sure. It's a $1mm out of production ride.

but it takes the WHOLE DAMN TRACK for it to catch up.

bad driver or not.

see, in a plaid, my wife could do a 9.3 1/4 mile. (918 does 9.8 WITH A GOOD DRIVER) Plaid doesn't need a "good" driver. that's how the world is changing.

I don't like this fact any more than you do. The world is changing.

 

we must have watched a different video... the 918 passes it after about 1 second then destroys it

 

Still in the process of tuning it. I keep getting a misfire on cylinder 1 at WOT runs up around 100mph so that's put a kink in things. It hasn't been on a dyno at all.

 

ah, I see now. my fault.

that's an older P100D not a Plaid. HUGE difference.

my vid shows you the difference a Plaid makes.

 

sending good vibes in your general direction.

 

is that the one (or maybe its all) that the battery is dead if they do 10 runs (in insano mode or whatever)

if so we just need to race 21 times lol ( hell Ill run him 21 times in my tundra )

 

Hopefully that helps cause so far nothing else has. Ruled out plugs and coils so far. ProSpeed had us re-gap the plugs as well. No luck. Another installer suggested maybe an issue with the cat. Will be checking that today.

 

I think I would tear my Tundra up if I raced it 21 times.

this dude drives his plaid home after whooping ass all night.

_____

dunno about low battery stuff. this dude races a bunch times in one night. 1/8th mile 6.05sec 120mph!

I am not a tuner...as all could tell you. but the sticking point with my truck was the injectors (DW650's). they spent all day on the dyno fiddling with them. are those ruled out via a good tune?

 

The injectors are brand new with the ProSpeed Fuel system and we're about 8 revisions in to tuning with ProSpeed, so all I can say is ..... I assume so?

 

Why did you have to show me this? Now I'm trying to find $12K and a trip to VA
