Drift-Office : Jackson Racing Supercharger Installed! (Tune Tommorow!)

[OICU812]

92 gas honestly that looks great far better then what I had guesses really. Overall Bob with all kits you've seen and been involved with were you impressed?

Bob any other mods like an exhaust, headers, ect...

That's exactly what I'm looking for. My god that's perfect.

Bob, was there a base line run for this car?

Here's the dyno sheet... and something to keep in mind :

We're running a winter blend of 92 Octane and I'm sure I could squeeze a bit more but given the variables, this is more of a conservative tune. We're also running a custom Speed Density (SD) calibration, and understand that when you do this, you're not looking at some E-Tune or off the shelf map. When going to SD, each car's engine has it's own VE, and there is no one size fits all calibration, at least not for optimization purposes.

Anyone purchasing either of the SC kits should save themselves mucho headaches and head to a local on-site dyno tuner and expect to pay more $$$...

Have a good weekend Y'all!

any chance to see the potential of this kit on a normal tune instead of a SD tune?

JR had said it was possible to tune it off the MAF, though I respectfully disagreed. Not sure how they did it but I couldn't without skewing the MAF values beyond it's intended range... To each his own I guess!

Man - totally forgot about that. Let me see if I can pull up the dyno runs remotely... ah, here it is! Baseline vs HKS EL tuned vs JRSC installed & Tuned...



And how about that 100+ WHP gain?




Cheers!

Those are really good numbers!

Will there be heating issues if you run this kit with an oil cooler and larger rad for long runs? (5+hours?)

are you telling me that the JR S/C is not possible to get tuned without SD?

Because I have no tuner here where I live that could do it... and I don't think SD is achievable via E-Tuning plus I would prefer less power but more flexibility of a MAF tune.

No, that's not what he said.

What he said was while JR told him it is possible to tune the vehicle with a MAF based tune he noticed, while trying to do so, that the MAF ended up reading outside of it's efficiency range (i.e. during WOT pulls the MAF was not reading consistently).

The inconsistency of the MAF could lead to skewed fuel trims, and thus a skewed tune, once the dyno tune is complete and client gets the car back and does some driving. To prevent these types of issues that could throw off the trim Bob decided a speed density based tune would be ideal in this situation. He did not say that another tuner wouldn't be able to create a MAF only tune. Just from his experience that it isn't the best route to go with.

Now, you don't have to run a tune based solely on MAF or Speed Density. It's very likely that you could run a hybrid tune of both. You can run MAF and the map would switch over to MAP for speed density as the MAF reaches the point where it's becoming unstable and thus unreliable.

With that being said, Bob @Drift-Office stated and I wholeheartedly agree, "Anyone purchasing either of the SC kits should save themselves mucho headaches and head to a local on-site dyno tuner and expect to pay more $$$..."

He further goes on to say, "...and understand that when you do this, you're not looking at some E-Tune or off the shelf map. When going to SD, each car's engine has it's own VE, and there is no one size fits all calibration, at least not for optimization purposes."

So yes, it can be done. Will it be optimal? No.

If that doesn't answer your question, I don't know what will.

I got it now but It goes back to what I wrote before, what if I don't have any dyno shop?

Is it possible to tune the JR for LESS whp/tq and so use the MAF instead of a SD tune?

I see lots of S/C around that don't have to use SD tune, so is It something related to this supercharger or is something related of trying to get every whp possible out of the kit?

The tune isn't about extracting every whp possible. Tuners target reliability and driveability.

Some setups lend themselves more towards SD or a hybrid tune as opposed to MAF based. It's in the design of the system. The intake's and diameter as well as MAF placement and other variables can pose difficulties with a MAF only tune, this is where the hybrid and SD tune comes in.
@Drift-Office stated if you're looking into one of these you should find a shop to dyno tune instead of eTuning. You should heed that advice. I drove 10 hrs on cruise control for a proper dyno tune in 2007. Other members of this forum have had their cars towed to a shop for a proper dyno tune. I cannot stress enough how important that is.

You maxed out the maf? What's the diameter of the maf tube on the kit? I'm running 14psi on a gtx2867r and just approaching 4.9v, with I believe a 3" tube.

[digital_assassin]

I think placement of the MAF on both of the rotrex kits is the reason MAF tune was ruled out. Bob may have some suggestions if you want to fabricate new parts to make MAF tune doable
