General Supercharger Thread.

It needs no explanation, it needs no excuse.
As the bear shits in woods, it just is.

 

PSB-1 owners, do I need the relay? Also the instructions refer to red and black wires. I have blue and yellow.





The red and black are part of the harness that goes to the gauge.

Do I need the map sensor?

 

Tank is at 12%, Walbro 450, '19 non flex basket my cluster came from & Radium Venturi, getting ready to go in today.

 

I don’t have the PSB1, but I’d use the relay to isolate the IGN circuit (or whatever circuit you’re using) to add another layer of protection in case something shorts out. I wired my AEM that way and went out of my way to purchase the relay separately as it wasn’t included. It will also be less load on that circuit since you’re just using it as the trigger circuit and taking power directly from the battery.

 

On mine yellow goes to battery + and blue goes to battery - . I wouldn't follow the colors so much as the numbering on the relay and their diagram.

 

Thanks, it is temporarily in & I did use the relay.

Tank is coming down, be back when I'm back, cover me, it's my first time & I'm going in!

Mr. Snivilous, did my email last night go through?

 

Oh I just saw the datalog, didn't realize it was attached. Give me a minute to look at it.

 

I was in no way rushing or complaining, I thought it went to spam or didn't go through. Thanks & I'm really going out there .


lol

 

Sent you an updated tune. Tweaked the MAF settings, and you're not maxing out the MAF anymore with the 4" intake so that's great.

 

Tank on the way back in.

 

It runs & the gas gauge is correct!, just have to button it up!

 

Shake down cruise 45 miles each way to Cave Creek to get a table. My Son & Daughter are in town & taking my Wife's car and our other car in different directions tomorrow, so my Wife is taking it to work, first time she is driving it in over a year & I'm too beat to put the plates on, hope the garage at the state capitol is secure!

 

Have all of you with you with Super Chargers done a Dyno run? I ask because if the limit for the Tundra motor is 600 at the crank how would you know what you are pushing for Horses?

 

I dyno’d stock 282whp

I ended up with 477whp

so I added about 200whp

200 + 381 stock crank hp=581

or thereabouts

 

Crank is good for more. Rods and pistons aren't.

Fireman Dan's build was pushing ~570 to the wheels on E85

 

This was Dec 2020, before I upgraded to ARH 1 7/8 headers and did my fuel mods. After installing the headers and going back for a touch-up tune, ProSpeed said my truck was losing fuel pressure at higher RPMs but was over 600HP on their hub dyno...I didn't get a final number. I will be going back with my five-o injectors and getting a touch-up with dyno numbers.

 

I want to make sure with what is coming up to have a nice safety margin.

 

Before driveline loss that figure would be slightly higher.

Sorry was e70 fuel

 

Mind if I ask what’s the official mod list for that dyno run then? Curious as compared to the Magnuson truck they used for their write up on the Prospeed intake and RCF TB.

 

Harrop 2650 w/85mm pulley, ProSpeed intake and fuel system, RCF throttle body, JBA long tubes with JBA mid-pipes, Gibson dual 2.5" exhaust

 

I'm tunning & dynoing 3/27. I will post my results.

Have not seen the gauge on full in a year!

 

With the blower, it never stays there for long!

 

Haulin ass with a full tank o’gas

 

The gauge when full was under 3/4 because flex sender & non flex cluster.

 

Nice. Congrats on completing your project.

 

The bigger issue is heat + tight ring gaps + weak lands. On one of Viktor's vids he grenaded his engine at around ~5PSI; probably after several back to back runs but no details were given.

It's cool, the blower will double your gas mileage!
