Full throttle Electric Supercharger Build Thread

The way I do gear pull logs is I get into the gear (2nd or 3rd) and cruise down the road and hold the throttle at the starting rpm (like 3,000). I then floor it to 100% throttle and run it all the way to red-line then shift and let off the throttle.

After doing a couple of runs I download the log and upload to datazap.me

First I turn on just Throttle and zoom in on a section where I went full throttle. I then turn on RPM. This is what that looks like:




I then turn off Throttle and turn on AFR to see how that looks:




Finally, I turn off AFR and turn on boost to see how that was. Notice there is a ~1 second lag between full throttle and boost pressure and for some reason no boost is being logged as 72lbs of boost...



I'm still running lean for some reason and have a bump early on (< 5,000 RPM). I'm going to get this straightened out once the e85 tune comes out.

If anyone thinks this isn't the right way to run gear pull logs please let me know. I'm by no means an expert!

Dude you have almost 4 psi at 5100 rpm. That is damn good. Bet that feels really good.

Seeing 4.5psi max, holding 2psi until redline. Not bad. AFR doesn't seem as clean as it did with the single dump pack though.

EDIT: Interesting to see how much max boost drops off on a sustained 2nd - 4th pull:

that AFR looks damn good to me. Whats wrong with it?

To the guys that just got their kit, when did you order? And how long after payment did you receive it?

Rob only accepts payment when he has the product in hand. As best as I remember (don't hold me to the exact timeline), I let him know I wanted a kit probably 6 weeks before he had kits in hand and he told me it would be mid-May when he had them. He updated around late April to let us know they'd be in early-mid May and asked for commitments to buy. They came in when predicted and we paid as soon as he received them. He shipped within a couple days (takes a bit of time to box them up). Shipping is from Canada, so if you're in the States, customs holds them up for a couple days. Total time from shipping to delivery was one week for me - he shipped it on May 16 and I received on May 23.

Hey fellas,

Latest log pulled a couple minutes ago, couple 3rd gear runs, then a couple running through the gears.

Car's feeling fanTASTIC!

a big to @Robftss for such an ingenious performance mod!

Hellfire uel mode active! Sounds like a monster and is feeling really good. Gonna try some vids today

Your spike looks similar to mine but comes down faster than mine. Until we get new tunes I would stay off the boost under 4k - 18:1 AFR is pretty lean.

Got my makeshift mounting set-up for OFT + Phantom volt meter:



Just used some 3M velcro pads. Makes it a little tricky to operate the stereo/gps but i wont be using it all the time.

I was about to ask about this. The most I'm seeing is 3.78psi with the 1.5 dump pack...

Do my batteries need to condition longer or should I check over my connections again? I've been doing a lot of pulls since Friday night...


Here's a 3rd gear pull:

Phantom ESC - 3rd Gear pull - 6AT

All depends on your altitude because the oft doesn't account for atmospheric pressure.

Find out what boost says with the car not running but turned on.

Don't forget your batteries may not be conditioned yet. Also on my 1.5 pack I won't hit my 4.5 max until I've done 2-3 decent pulls.

I can usually only hit those numbers at below 3000.

~4 psi at or around 4000 to 5000 is very good especially after only a few days of boosting.
