    P2 Supercharger Thread

    The P2 is basically a Vortech Si trim.

    2L Opel GT e-boost build

    Nice. Sorry I've not been focusing on this forum - the barndominium build has been all consuming. But we're nearing the end. Stainless may not be the best choice, since it does tend to warp a lot more than say mild steel, but I'm honestly just guessing. I do know that in my talks with...

    Water Meth injection instead of a Intercooler ?

    Yes, I did. I ran dyno tests and track tests. Picked up good power: Here's the data deep dive: Here it is at the track:

    I Stand With Ukraine

    How are the Ukrainians supposed to hold free and fair elections with international observers when 20% of their territory is illegally occupied by genocidal, murdering ruzzian psychopaths intent on killing all Ukrainians, destroying Ukrainian language and culture and lobbing massive cruise and...

    I Stand With Ukraine

    You've been told lies, and unfortunately chosen to believe them - tucker carlson isn't a reliable source (as even the courts have adjudicated him as not a journalist, but "entertainment"), and putin is a well-known liar. Let me present you with the truth, and I will encourage you to do your own...

    2L Opel GT e-boost build

    I really need a set of gauge pins myself. A one piece shaft is probably the best idea - looking forward to seeing how your turns out.

    Duryea 12v Electric Supercharger

    That looks to be a small roots unit like the AMR500. It's highly inefficient and very limited in terms of hp output - just over 100hp max. I find it odd that they claim 600 amps at 12 volts and it can run off a car's existing electrical system, but there's no way that would happen. They're...

    2016 Silverado 1500 5.3L

    What GTHound said. Though 2 psi isn't much, 4 psi starts to become very noticeable - it's about the same as 5-6 psi of conventional turbo boost.

    Full Time Electric Supercharger - Is it Possible?

    Boost at very low rpm is a bad idea. It creates a tremendous amount of cylinder pressure and can cause severe engine damage - it makes your tuning window small, can cause uncontrollable detonation, blow head gaskets, beat up rod bearings, etc. If you need more low end grunt, the best bet is to...

    Not too much activity, but it's building. I'm in the process of moving halfway across the country, so I'm a but inundated with both houses - selling the old one and building the new one. Moving day is coming up in the next couple of weeks - and then I'll be back on to these things.

    would this battery work?

    I tested several smaller batteries in a video here: I didn't test that battery in particular but it'll give you an idea of the range you could be looking at.

    would this battery work?

    There really is no standard for C rate. In other words you don't know what the voltage sag is going to be under that load. I really don't think any battery that small can provide the kind of current levels we're looking for. Generally speaking within the same chemistry, The greater the amp...

    Site "Not Secure"

    That would be a false positive. I had Godaddy (the host) take over the SSL stuff. Should be good to go.

    Hello!! I am Mateen from Silver Spring, Maryland

    Hi Mateen - how do you plan on connecting the 18650 cells? I have bought 180 a123 systems lithium iron phosphate cells but ended up not using them because I couldn't come up with a way to connect them all that could reliably carry the current

    Ducted Brushless Fans for boost?

    I don't think it'll make enough boost to make intercooling or injection worthwhile. On the other hand, I've always had a thing for Jaguar sedans - particularly the round eyes. One day...

    Hobbywing Max4 - EZRUN 70125 - Speedmaster P2 build

    This looks great - when you get things working, definitely let me know and I'd love to make a video with you featuring your build. I also like your packaging of the motor, btw.

    Ducted Brushless Fans for boost?

    Please do so - and if you do, I'd love to make a video with you about your results! Just let me know here in this thread.

    Audi SQ7 4.0 TDI - electric supercharger.

    That may end up being a heavy lift - you sound like you're miles ahead of where I would be with it. Can you share more of what you've discovered? Maybe some of the software folks on here can offer suggestions.

    Control methods for an E-supercharger

    Wow... just saw this. I did have arduino control but encountered some issues. So I switched to the simple method - two small servo testers, with one being zero throttle and the other being max (or whatever it's set to) throttle, with a relay switching between the two. It's pretty butch, but...
