FGT supercharger swap project

that is awesome!

Look forward to the Dyno numbers!
great work,

Hmm...

I giggled like a little girl seeing the blower sticking out of the hood like that. More machining p0rn please!

There's plenty lol



I'm pretty proud of that IAC valve body on the blower. It just came out great. I haven't even technically used it yet

Oh also in this picture is pretty much the whole LS ignition coil retrofit. The messy wiring is just a temporary harness for testing. I'll make a nice tidy one soon. The coil mount plates on the valve covers are water-jetted. The stands that you can't see I made on a CNC lathe. The enclosure for the output module board sitting where the ICM goes was pocketed on a 2-axis CNC bridgeport mill. The smoked lexan cover water-jetted.

current news


I just got some bigger injectors (for the 3rd time on this car). Even with an under-sized throttle body and the biggest pulleys, this churns out more airflow than the m90. In my logs I'm seeing maf values like 1000hz higher for the same rpm at wot. I don't bother with the g/s calibrated values at this point because my whole tune is scaled so they are not real life numbers.
Anyway with 80lb injectors on E85, I max out on flow in the upper 5000rpm neighborhood. So the car feels really strong up to that point and then I have to let off or throttle down boost (which I can now do thanks to the boost controller) But the bottom line is I'm held back by fuel.
I got a set of injector dynamics 1300cc (124lb) injectors. So now we will see what the fuel pump can support... I have a feeling i'm going to be changing that too.

Those injectors look HUGE!
Sounds like the pursuit of higher performance is like a game of whack-a-mole with a mallet made of Benjamins.

They're actually smaller. The bit above that metal clip is just an extension neck so they fit this application.
So now I guess I'll install them, tune, and determine where I start seeing fuel pressure start dropping and keep it below that point until I can address that.

gah, it all fits together just like it was made for it, because it was!

Dude....nice

You had me giggling like a madman. Have any videos?

I aught to have a juicy video soon
I'm hoping to take a trip to the track for some test & tune on sunday as long as they stay open

Well played, worthy adversary

I was wondering if there's any reason to cover the hood cutout somehow.

Do your injectors fit with the connector being that low? I bought id1050x with adapters so the electrical connection would be higher and they are still very close.

It's close but they just make it with the stock valve cover height. My front valve cover has a .35" spacer under it and the injectors barely fit but the connectors wouldn't go on without some circumcision. I trimmed the outer shell a little and they plugged in fine. The EV6 connectors have a lot of unnecessary shrouding

I need to. Rain and stuff getting all up in there is no good.
For temporary purposes, I'm making up a plexiglass cover that's not going to look very good but cover it up for now.
Once everything is all finalized which will be on a different hood altogether, I'm going to have a specialized shop form up a cowl of sorts using another layer of metal from another factory hood so as to blend it all out so you almost don't notice the increased height (hopefully).

I see.

would it have less air resistance as a pass-thru scoop of some sort?

The season is over and i'll be putting the turtle into hibernation after this weekend, here's the update.

FGT setup has some miles on it. - speaking of which, I've never seen my gas gauge go from freshly filled to about 3/4 so fast as today - no joke maybe 20min of driving
I did not make it to the track either of the two weekends I was planning because it was closed due to weather both times and it's probably for the best because as fate would have it, they would have pretty much been wasted days anyway.

The first week I figured out that my breaking up issue at full load was due to lack of fuel primarily on account of my easyperformance voltage booster quitting on me. It was working in pass-through and not boosting voltage like it's supposed to. I threw my old magnavolt voltage booster back in there which is a bit less juice but enough to eliminate the breaking up issue. I found out today that it's definitely still not enough but If I keep the boost down below 19psi or so, it keeps up and that's a nice bump in power still.
Oh the second day that I would have gone to the track, my old tuning laptop just sorta stopped booting up which kinda screwed me over too. That would have ended my 2nd would-be track day right away.

Today, I had some time and after getting my newer laptop set up for logging, I did some pretty thorough road testing and got some good info. The thing makes f**kin power. With the exhaust completely choked with stock mufflers, I was still seeing up to about 11300hz at the maf after 70% scaling (map ends at 11500). Boost currently is steady 20psi until I guess about 6k rpm and then it peaks up at like 23 and then fuel pressure very quickly starts disappearing. That's with the cutout closed and on that note...


After my driving around I spotted this and was like wtf obviously


then I looked underneath and saw this. Both new mufflers are literally busting open at the seams.   They can't handle the 3800 powers

What else?... I got the LS ignition setup all done with new wiring. It's been working fine. I installed my electric water pump. Works great as far as I can tell. All the wiring I did for the LS ignition, water pump, IC pump, etc. I integrated into the factory fuse/relay box under the hood using the empty spots in there so there's no more relays and shit just hangin out places. New boost controller works awesome which is a godsend after the nightmare I went through trying to make the easyperformance one work for me.


I've got some in-car footage on my gopro - i'll trim all the nonesense out and post it soon. Nothing too nuts

That was fun. How much power does it take to bust mufflers?

...I wish I had pictures of my exhaust setup to show you. If it might interest you PM me about the PAU exhaust setup.

I finally figured out good video rendering settings for uploading to youtube. It would always look like compressed-to-death garbage. This looks nearly as good as off the gopro 1080@60fps. If I did nothing else today I'd still be happy

Anyhow these short clips were test runs from that day I exploded the mufflers and was totally running out of fuel at the top end. It was haulin! When it can breathe and has enough fuel which I'm making progress on, it'll be somethin

Sounded good at the end!

So far I've missed out on the fleeting opportunities to get this to the track but the longer I delay, the farther along I get so I guess it's ok. The rain is driving me nuts though. Here's a shitty video for today.

I got the double throttle mad scientist project fully functional and working reasonably well. Typically you open the throttle to 90% and it's near as makes no difference 100% but now it's like a 2x volume knob for the supercharger and more pah cause better diabetic effishesies or somethin. The motor is takin it like no thang at all.

I really want to get to the ZZP dyno day. It's gonna be tricky since there's still gonna be rain all over the place and I have a gaping hole in my hood and things I don't want drenched in water
