CT4-V Blackwing Tuning Update from Tapout

[WONT TAP]

We just wanted to give you a little taste of what we've been doing with our CT4-V Blackwing.....

100% OEM drivability aspects have been maintained below 3,500 rpm. Above 70 to 80% accelerator pedal position, things are starting to get ridiculously FUN! At WOT in Track mode, the A10 cars upshift between 6,400 and 6,500 rpm, so you're always running between 4,700 and 6,500 rpm. We have significantly modified the powerband between 4,000 and 6,500 rpm to cover both the A10 and M6 cars.

Tuning is nearly complete. We just have a few small items left to resolve. All details of our CT4-V Blackwing Performance Packages will be announced in the near future.

Stay tuned!

Awesome and call me selfish but I wish the topic was for a 5.

Are you tuning the A10 (TCM) as well?

Are you tuning the A10 (TCM) as well?

No, since it already feels perfect to us!

 

[Bigfx]

I was really wanting to keep mine stock too..oh boy

 

[hoooogan]

I'm in a holding pattern to start shopping for a 4BW. This is not helping my itch.

Are you on pump 91/93 or flex fuel? Any other mods outside of the tune?

 

[RDATLTE]

We were going to fly to see our son outside of Columbus...

+150hp/+160tq AND I get to eat a Thurman Burger?

Do I need to put this Thurman Burger on my must try list?

Yes, yes you do. Get there early and leave time to wait, if its a busy time of the day.

That's a lot of boost. ~15 psia additional? Gotta be some E85 up in that tank.

Crazy power gains though, nice work.

 

[DustinEarnhardt]

Speechless. That is an insane amount of power on top of what this car already has.

Also, please correct me if I'm wrong but, aren't we talking all tune in OEM configuration with no aftermarket components added?

Scott did say "Performance Packages" so that tells me more than one, and likely needing some mods to achieve these latest numbers. Fingers crossed the latest dyno is on pump and not E85 and/or meth.

Here's what I am wondering.

The ATS-V, all of them had the titanium con rods.

The Blackwing, only the manual gets them.

So I assume you will need to be a bit less aggressive, maybe less timing etc on your 10psd auto.
From there, would you have a tweaked tune, maybe a teense more aggressive for the manual cars?

I dont think you can make that assumption. Steel is actually stronger than Titanium (other than some less common alloys of each), titanium is just significantly less dense. If your looking for an application where weight matters, like the rotational inertial response of the connecting rods or the longerons in an aircraft, titanium is absolutely better. But if the rods are the exact same cross-section, the steel ones are usually stronger.

Well then, considering the ATS-V's LF4 has done 600whp easily, then theoretically the BlackWing Autos could handle MORE boost? And yes, I was confusing the lightweight advantage of the titanium con rods with overall strength.

Must I be reminded of this?

Hey, you 10spd guys get the faster quoted 0-60 and 1/4 mile times

 

[Throat Yogurt]

Wow, +170 lb-ft! I wonder what that is going to do to all the downstream components- clutch, diff, drive shaft, axles, etc.
