This is what i was refering too(mostly the baseline of the cheapest full time FI kits). Below is ThaTruths conservative tune overlayed ontop of a Innovate SC kit with base tune and also Water meth injection on the top line.

Now you cant directly compare dyno's as we all know but it really does provide a nice curve comparison.

If you consider my more aggressive tuned top end you can see it is biting at the heels of a full time FI solution(base tune).

Thats pretty exciting and i think it is enough to call this "getting close" to full time FI numbers.

Of course it is never going to beat a 5000 FBM or FA20 turbo kit but that was never the intention of this kit.

This is as much fun as you can have with the littlest amount of capital invested.

Updated First post with 0-160 and TQ250 boost vs TQ300(experimental) boost.

Update:
TQ300 compressor testing. Did a 0-160 untuned. Below that is a boost plot of TQ250 system vs TQ300.

Looks to be an average increase of 1 psi across the full rpm range. Nice result.

Damn you. By now you'd think I'd remember that you're in Canada and stop going "holy crap that car got seriously fast!" only to remember that's like 0-100 in US terms.

On another note, those guys who are complimenting your patience are understating things by a bunch.
I'm nominating you for canonization.

Its worth noting that this 0-160 was done at +3500 feet..... It does feel really fast

I can't wait to see how this continues to develop and also what my results will show when tuned.

Come on, quit drinking the kool-aid.

Other then that, I have no comment on anything else going on in this thread.

Well at least a consideration for worst possible case heatsoak.

The point I'm trying to make is that we didnt have the hood open blowing dry ice in the intake to get these numbers. We just strapped to the dyno and went.

Reality: running just this, you will never deal with heat soak, your e-no2 system does not generate any extra heat when your not WOT, so sitting in traffic, no effect, in fact I think the only time the E-no2 would ever have that issue would be if you wrapped it up like a present as seen on one of those old Lexus or nationwide commercials and then drove it WOT. I think the bigger concern would be a temp sensor attached to your stack-o-batteries, I think telsa and the Prius May have an example you can follow. Battery heat does increase phantom charging rate, maybe a break duct like system to your battery area, obviously with some sort of u bend to drop any water out of the air stream.

We don't really have to worry about that here. Its cold as hell for 8 months of the year. Our issue will probably be keeping temp in the batteries for optimal dump.

This thing will heatsoak just not as much as other typical fi. The charger sits right above the headers so gets a bit of heat there as well as the airbox.

One other thing is the control box, if it gets too hot it limits power..... One of the reasons we did the tests with hood down was to make sure there wouldn't be any unforseen problems.

Thanks for the ideas on brake duct to battery cooling.... I can see this being useful for the Arizona and other southern guys.

What do you call this? "Quit drinking the kool-aid". Really.
But the comment wasn't specific to you, by the way. He even puts up with me when I won't let something go.

The batteries used are simple SLA type batteries and do not have the problems with specific charging/discharging that Lithium batteries have (Tesla & Pirus). Getting the SLA's a little warm help with their ability to dump a lot of current in a short period of time.

And for what it's worth, this cool-aid tastes damn good.

I'll be happy to drink some kool aid. I got a dyno waiting to play with that awesome drink.

*breaks through a wall* OH YEAH!

[bfrank1972]

Well then I don't get the 'kool-aid' - typically that's used as a mildly derogatory statement towards someone who blindly accepts someone else's 'truths'. Don't think that's what's happening here - seems Fenton is plenty happy with what he has installed (especially the new stuff), and I don't think he's stretching the truth to us. That's just me though, guess I'm the naive 'kool-aid' type.

Oh, btw, do you drive around with your hood open? I'm not sure there's a 'correct' or 'proper' way to do a dyno, but maybe I missed my dyno etiquette book in finishing school. Dyno how you want, based on the conditions you want to induce, and get the results. Hood down on a dyno is worst case scenario, and it seems Fenton wanted to 'stress' the system, not get really 'good' numbers. I guess he failed though, because nothing broke and the numbers were awesome!

[fenton]

He is just saying that dyno;ing with the hood down isnt real world and many people think that it is. The only reason we dynod with the hood down was to simulate worst case conditions, we still had a fan in front of the car.

Depending on your fan speed it could be real world but most shops don't have fans to simulate correct wind speed.

In my opinion, 'real world' and dynos never go together. A dyno is a great tool for measuring results, and comparing them to other results, given it's done in a consistent manner. Hood open, hood closed, big fan, little fan, dry ice, none of it is real world - too many other factors come into play. There's not even a standard 'real world' to aspire to. 'Real world' at 35 degrees F vs 'real world' at at 90 degrees F. 'Real world' intake/oil/water temps stoplight racing vs 'real world' intake/oil/water temps at extended track events. You certainly know that 'real world' at +3500 feet is different than 'real world' at sea level. I'm all for the critics, but I prefer critics that at least back up their views with relevant and constructive points.
