So if using EcuTek boost control, does it help or unnecessarily complicate to have an independent boost controller in-cabin? Considering merits of Innovate SCG1 vs PSB1.

For $40 more the scg-1 let's you dial in boost per psi. But, it's not as fast going from say a daily map of 10psi to a kill map of 17psi. Plus, you will be tempted to dial it up "just a little more" lol

What would be your purpose for having an in-cabin boost controller if you already have the ability to change the map/boost pressure via the ECU?

Because then you can literally dial in whatever boost you want from 10psi up to 20+ psi. I dont think your tuner would want to have you upload 50 maps. Do you really need more than 3 boost levels? most dont

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 mean, hell…. I plan on running 2 maps. Hi and Lo, with a flex fuel sensor…. I guess I’m mature enough to know “just 1 more pound” is like going back for a 3rd plate on Thanksgiving…. It’s all sh1ts and giggles, until someone giggles then sh1ts at the repair bill. :driving:

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 :rofl2:

New Dyno graph. 710whp/533wtq!!

10psi, 15psi, 17psi.

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

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. :tiphat:

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. :driving:

e71

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

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!

Do you have numbers for 91/94. we don't have any E-anything in ontario.

From Birdie's post earlier:
I hit 464 whp and 406 torque on pump at 9.5 psi

yeah wondering more how much psi is safe on pump. before you'd expect knocking i guess.

Like what could i realistically expect from this kit. on pump. i guess good safe numbers for stock internals would be helpful. also interested in what it could do with a built motor and 94 octane. if that makes sense.

You would need to work with your tuner on that. There are more variables to consider. How much fuel are you able to provide? It's not really the pressure that will cause knock, its timing and running out of fuel for the amount of air (pressure) that you're shoving into the engine.

I'm at about 14-15psi on my V1 topgunz setup with no issues.

Stock internals record is like 800hp, I think. Reliably, maybe 650? Depending on your tranny, wtq is gonna be the killer. <425-450wtq is where you wanna be WITH a tranny cooler for us 7AT guys.

Update... 802whp on the Rotrex kit!

Another update...

370Z Supercharger 1/4 mile RECORD!! 10.3 @138mph

https://dynosty.com/we-accidentally-...4-mile-record/

BTW...the car also made 600wtq.

yeah i mean assuming other variables are sorted.

My plan is the radium surge tank with new fuel lines and fuel rails. Should be able to put as much fuel as any kit needs.

What kit are you planning on running?

Your kit hopefully!

if you meant fuel setup.

Not sure what kind of power you're planning on making but you may want to think about 1300cc injectors. You can run out of injector real quick with 1000cc

i'd like 650WHP on pump gas. worried about the already high compression ratio of the vq37. was thinking that's relatively conservative numers these days on this platform but would definitely step up the injector if necessary.

What octane do you have there? 650 on pump might be out of reach. I had 1050 injectors and a single walbro 450 running e85 and my injector duty cycle was at 125% at 650whp. I had to go with 1300cc's and twin pumps

Just 94 at certain pumps. 91 everywhere else.

What pumps did you go with? I'm considering a TI automotive brushless pump and wondering if one will do for around 650whp on e85.

91 might be pushing it. 94 should be doable

I kept my walbro 450 and added a 525 hellcat

Ah, so I'm guessing that one pump isn't going to cut the mustard for me.

Honestly I think it depends on your fuel set up as a whole. Seethroughead is wanted to get up to 650 on pump which the 1050cc should be enough as long as he has the rails to go with it. (Although 580 to 600 may be a better number).

redondoaveb ran out of duty cycle but keep in mind he was running on e85 so takes more volume/fuel to get the same numbers that's why he needed bigger injectors and pumps.

I hit 650 with rails and the hellcat pump running 1300cc injectors at under 80% cycle.

Keep in mind you are be going to want to move volume over pressure. I feel like you shouldn't want the pumps fighting each other. But again depends on your setup as a whole unit

See Birdiev post :tiphat:

Yeah fair points. I hadn't planned on changing the fuel rails, but I do have 1300cc injectors already so maybe I should reconsider. $1400 on fuel pumps alone seems pretty insane, but I know I gotta pay to play. I might run with 1 pump and see how far Eugene can take it and then decide down the line if I want bigger numbers.
