General Supercharger Thread

It would be plug and play but the break out harness doesn't support Toyota; requires tapping pin 1 of the "GO" pedal.

I'm adding it to the list of shit I don't need.

Only gripe is there doesn't seem to be a way to tune it at home.

 

NICE!
The only thing I'm not looking forward to will be having to likely install another, slightly shorter serpentine belt. I think I donate more blood to the drain in the shop floor routing belts than anything else.

 

Please sign me up sir!

 

Do you know if your engine was built with larger piston ring gaps to handle more boost? If they were gapped for 15+ PSI boost and If they keep knock under control, they might be fine with 93. E85 would cool things off considerably, but expensive to do on our rigs as would require a standalone ECU like the Motec mentioned.

Once you start getting up to 20+ PSI though, regardless of ring gap, you're going to need something to cool off the charge, whether it be E85, or Water/Meth, or Nitrous...heat's going to be a problem.

 

I didn't look around at shorter belts so we'll have to see how that works... Larger pulleys have a lot more circumference change albeit more grip length for the belt so we'll have to see how it plays out. The 77.5mm is about an inch less circumference, and the 70mm is about two inches. I don't know how much belt length engagement there is, would you be able to get a picture of that? There's a Gates 115.0625" belt which is about 1.125" shorter than the stock belt, so that may work for one of those pulleys.

 

Ya, I'll get that for you tomorrow.

 

As @armyoffoo stated you can tune for water/methanol injection running 93. Especially if e85 is hard to find. You'll get cooler IAT's. There's the upfront cost but it pays off.

 

This is Nat Speed's hidden E85 Stage 4(their website is still jacked up); may give you some ideas:

<li>Harrop Engineering TVS2650 supercharger system</li>
<li>OEM Lexus RC F 84mm throttle body</li>
<li>Prospeed Autosports 4.50" air-intake system</li>
<li>ZPE GripTec 75mm supercharger pulley</li>
<li>Prospeed Autosports ethanol compatible return-style fuel system</li>
<li>Ti Automotive 450lph in-tank fuel pump</li>
<li>Prospeed Autosports 750cc/min fuel injectors</li>
<li>American Racing Headers 1.875" primary ID long-tube headers</li>
<li>OEM Toyota exhaust manifold gaskets</li>
<li>NGK LFR6AIX-11 spark plugs</li>

I thought it was a twofer sale when I saw it in my inbox. So disappointed.

 

Speaking of rings did you ever get the Total Seal rings installed or is that for the built bottom end?

 

Not sure how Nat Speed was doing E85, been a while since I asked about "Stage 4". No Motec was required or at least not listed in their parts list, total package was $20K about $6K over Stage 3 (basically headers + Stage 2 + all the PS upgrades + TB)

 

This was an E85 build showcased here:

Nope, still sitting on the shelf with all the other parts...I need to call the engine shop and see about getting on their schedule, and stop procrastinating. I need to get the mains line honed for studs and I bought bigger valves from XAT that I need to get head work done to accommodate, then I'll have them measure clearances and static compression.

 

The 4x4's already have flex fuel, but most people bypass / disable that system when tuning...from what I understand it's not reliable, or there is another issue with tuning it.

 

Didn’t know that about the 4x4s, good to know.
I think he discusses the issue a few posts down on the first page

 

Few dependent things here. Boost level and octane. You can only run so much boost and timing on pump gas. More octane more timing more power. Or displacement etc

 

I followed alot of the mods he made to the fuel system and intake with W/M injection. He said he was able to get decent results with 93 and W/M compared to e85.

 

Makes sense. They are both enriching with an alcohol.

E85 seems like a pain to run especially if there isn't an abundance of stations nearby.

 

I'd hope so, methanol has an effective octane significantly higher than that of ethanol lol your effective octane rating with a blend of pump gas + methanol would be much higher than with pump gas + E(xx)

 

First tank of gas through the truck since the blower install. Stock Maggie tune on tvs2650. 12.4mpg

I have been driving 50% normal and 50% buffoon. Not too shabby.

 

That'll go up, or down, rapidly depending on how you end up driving lol

 

FYI, Innovate has 10% off gauges til sunday. PSB-1 for $274

 

Well, crap…

 

I’ve got a smaller pulley with your name on it lol

 

Andrew from XAT sent me some pics of the short block, I should see it soon.

 

What all is he doing for you with the build?

 

Forged bottom end, upgrade oil pump, dampener, balance everything.
