However, I am not sure all tuners are capable of actually knowing how to control the solenoid. If they cant, then a boost controller will be required.

I know the purpose and function of boost control however, my question wasn't directed at you TGZ (hope I'm not coming off as a d!ck, wasn't my intention). It was more to make a point: How many forms of boost control does a single, street-driven car need, and why use the boost solenoid if you're just going to go and mess with the boost controller after that has already been setup?

That was my point... no one needs "50 maps" when 2-3 will be enough for most. On top of that, paying to have ~3 maps specifically configured then going back and playing with the boost controller on top of those tunes have been calibrated is just asking for trouble imo.

But hey, I only pay for my own car so what the next guy/girl does is up to them.

Boost per gear gonna be more practical than set and forget solenoid duty % imo.

What would be cool is a trim knob that could tell the ECU to increase boost target across the whole map, while still retaining the boost by gear targets.

You would not use both forms. You can only use one solenoid so you would either use that solenoid to be controlled directly from Ecutek/ECU or you would control it from the boost control head unit/gauge.

I may have confused some guys when stating "50 maps". We run the scg-1 in the RnD car and the car was tuned by a good tuner (Eugene) who sets this thing up so that the injectors automatically scale to the psi the MAP sensor is reading. Therefore, you have unlimited boost bandwidth. Meaning I could go from 10 psi up to 20+psi in .5 psi increments and the cars AFR's would be spot on at any given psi/herspers.

Kind of nice if you have it set to 11psi for a daily but drink a lot of coffee one morning and decide you want to drive to work at 13psi instead...lol..

That's what I was saying

New Dyno graph. 710whp/533wtq!!

10psi, 15psi, 17psi.

What is also impressive is 453wtq at only 10psi!

Averying · 09-30-2021, 03:41 PM

Wow. At 10 psi this kit is making 70 more whp and 50 more wtq than my GTM stage 1 kit running similar boost. Awesome stuff.

What’d be the biggest reason for this? More efficient air flow/temps from the upgrade blower and intercooler?

Are all 3 runs on e85?

Great numbers. The car that lifted the heads made 708 at 22 psi. How did this one make 710 at 17 psi? 710 at 17 psi is super efficient and for the most part won't have to worry about head lift.

The reason is two fold. The intercooler is definitely a much more efficient cooler and the other reason, the more pronounced reason, is the way we set up the boost blow off. This thing ramps boost in much quicker than any other kit since we spin the blower up faster but then dump the excess. This basically just shifts everything to the left on the graph.

We were WAY out of fuel on the 708 run and couldnt do much at that point. Also, we are definitely up against a very tough reading dyno. This dyno made 628whp on the ACE kit but 685whp on another.

As you know, there are lots of factors that determine a number on a dyno. You also know that some tuners throw an aggressive tune at a car and some tune for safety.

Thankfully we use tuners that tune for safety

Good numbers though. I'd definitely be running this kit if I hadn't gone turbo

Hey guys at about 7:35 minutes into the video I hit 640 whp and 497 torque at 15 psi .Sorry about the miss info the 10 and 17 psi numbers are correct .The 578 has to be around 12 maybe 12.5 not too sure but I will try and let you know once I get the info form the tuner.

Regardless of the numbers since all engines are different and modded differently .this was a bit more of what this supercharger can do and how you can customize it with ECUTEK on different maps.Main thing is the filter that keeps your air clean and has a cool air intake affect being away from inside your engine bay

turtle64b · 10-01-2021, 05:00 PM

Hey, I wanted to ask what injectors/pump combo was on when injector duty cycle hit 107%.

I also wanted to see where people are putting the SC oil cooler if the normal real estate is taken. I have power steering and tranny coolers stacked on the pass side and a 34 row oil cooler on the drivers side...

Hopefully I'll be able to join the ranks soon!
