General Supercharger Thread

Crickets from the shop, I assume until Monday.

I hate dealing with shops, asked the junk yard the blown motor came from for a refund, not optimistic.

 

Maybe...you did have a shop install it. Hopefully they can do something.

 

Nothing looks off with AFR, fuel trims are at like 2% across the board.

That's not a bad idea. Still doubt that fixes it. I've done times with 85 octane and you don't even have to pull this much timing.

 

For the overall small increase in pricing, it's one of those "while you're in there" decisions. For what has become a 1k HP build, the valves and springs were the only "upgrade" done over their standard build. Looking forward to seeing the block come together, too.

 

Yea I don’t think it will either but helps rule out one thing lol

 

Something loose and rattling around? Drop a tool or bolt down in the valley that's bouncing around close to the knock sensors?

 

He says the chain tensioner makes a lot of noise and is going to send me a video. That sounds like a plausible source to trigger the knock sensors...

 

Crazy! But makes sense.

 

But it's pulling timing during the knock events?

 

All the red is timing being pulled. The difference from -3 is how much is pulled. My goal is the whole table reads -3, worst case -4 meaning one degree is pulled. This truck is pulling like 7-11deg all over the place constantly.

 

Ah I understand. I always think of the knock retard reducing the timing and knock feedback detecting knock. But I'm easily confused.

Highest I've ever seen was -7.5 at partial throttle on new tune, nothing over -4 on wot though.

 

No you're right, I just tend to group them together since from my understanding knock retard is more or less slaved to knock feedback. So while they're not necessarily one and the same, they change together, so you're always getting timing retarded if the knock feedback is below -3.

 

That makes sense. And then thats when I'd usually add some fuel in PE if trims are good. You said Air fuel is good but wonder how fuel pressure looks, which you've may probably already checked.

 

If yours and the stock Magnuson tune are showing the same exact issue, I would have to point at something going on beside tuning. I seen fuel quality mentioned already. So I’m sure the owner has made an attempt to get the correct fuel in by now. So at this point, if the correct fuel is in, it is def something mechanical. How is the truck running with both yours and the Magnuson tune minus the spark issue?

 

This Harrop is still available if anyone wants me to look...good price-ish:

 

A) how is this similar?
B) what is it/ why am I thinking Breaking Bad meth lab?

 

Haha, man, "trying times" make great deals for those whom are patient! Imagine what you could make with a $130k machine at 70% off! Also, boost!

Honestly not sure what's going on with that CNC...perhaps he works there...also, perhaps it's a scam...not sure, but I'm educated on both items and have lived in this valley for 30 years...I could root.it out if interested...

 

I have no need for whatever it is and my supercriminal island lair is fully accesorized so for those reasons, I'm out.

 

That is soon tempting! If I weren't planning on a move I'd jump on it! I've already spent too much on small items.
I finally got my timing and afr's sorted out plus MAF. Where MAF is maxxed right at 6000-6400 rpm and afr's bounce between 10.9 and 11.5. Seems to be pretty peppy...

 

Boomslang firewall mount completed, waiting on the rain to stop then I'll mount it, figure out how to mount/secure the stock ECU under the dash and then begin wiring accelerator pedal, throttle body and sensors...this weather sucks but at least it's not 110+

It's not pretty, but it's good enough for who it's for. Original M6 bolts mount it to the firewall, M4 bolts mount the sandwich plate to the firewall adapter. I also re-pinned the injector harnesses with the ID 1050x plugs, so they are ready to install.

 

@armyoffoo looking good! The wiring would drive me crazy and take 3x's as long. I'd be triple checking and re-checking.

 

What's the giant red button?!?! I just wanna slap it lol

 

It's a cover for the bulkhead wiring pass-through.

 

I'll be contacting Magnuson soon..Need some supercharger tuning.

 

OTT or @snivilous can give a much better tune than what the canned tuned offers.

 

THIS!!!! ^^^^^^^^^

 

I second this.

 

Defaulers arrived we’ll see how they work.

 

Mmm...steak for dinner. I used the Vibrant ones before with good results for p0420's from LT headers.
