CT5-V Blackwing Closing in on 700 WHP

[Speed Racer 007]

Still no check engine lights or DTC's? How does it drive with the 103 TB and no tuning?

Based on what I've read online, it appears the ECU will self-adjust. The question I have is, until what point? Hopefully soon, someone will crack the code so tuning can be performed with data logs....

I see you guys have springs listed for the CT5 V! does the test car have these installed?

Very interested.

Our test car doesn't have them, but customers have already installed them and they're working great!

@WONT TAP How is the car behaving with the bolt ons? Cruise control, all functions, modes, etc. work? Also where is that video of the blue car that made close to 700?

With the springs, will mag ride still work since only springs are replaced?

the fitment on the front wheels should be a class X felony

I'm generally a fan of a big wheel like this. Something doesn't sit right however with that low profile of a tire. Maybe if the fit were a little more aggressive in filling the wheel well could help?

Is that a good thing or a bad thing? Hard to keep up with all the kids' lingo these days...

We get it bro, you drive a cadillac and are old like anyone who drives one, real funny pal.

Car behaves like stock until you mash the gas pedal. There are no known side effects to date.

I am not sure where the dyno video is right now. I will look for it tomorrow.

Mag Ride still works flawlessly with the lowering springs.

It took our team more than one year to hit 700 whp with the CT4-V Blackwing. The CT5-V Blackwing should easily cross that threshold next month, on pump... | By Tapout Tuning | Facebook

I wish you would stop posting this stuff because its killing me slowly!!!!!!!!!! I'm not going to ship my car to you so stop!

Today we did some more testing with the CT5-V Blackwing. Here are some of our observations...

1. Kooks header and exhaust systems are the best quality imaginable.
2. These cars sound very loud and aggressive with the Kooks systems installed, running in Track mode with the Active Exhaust Valves open.
3. They are still quiet in Tour mode with the Active Exhaust Valves closed.
4. We noticed black dust in the intake area. This probably means the supercharger belt is slipping. We will look into smaller/better supercharger belt options next week.
5. As a test, we did some pulls on E40 fuel. The high pressure side of the fuel system wasn't able to keep up with demand, and the fuel injector pulsewidths widened so much that the fuel injection window (which is very short on direct injected cars) was exceeded. This resulted in an immediate loss of ~ 100 whp > 6,000 rpm. Even with reduced ethanol content, we are too close to the limits of the stock fuel system. So our conclusion was that the stock fuel system cannot handle adding ethanol to the tank.

More information will follow next week. First we need to dump a half tank of E40 fuel and source a smaller/better supercharger belt. Stay tuned!

Where do you think it will end up on pump gas 720-730 whp? And are there any other mods that can be done? high side pump change or bigger injectors without tuning?

We can't change the fuel injectors without ECM tuning access.

We could change the HPFP, but that's a very expensive modification that might not net much gain without the aiblity to do custom tuning.

We could also try a fuel cam, but that's a really big installation job for potentially small gains without ECM tuning access.

We'll let you know the final pump gas numbers next week once we get back on the dyno.

Those instructions could certainly be better with much better photos. Like removing clips, show a before photo of what it looks like and how its mounted, then show it "removed"... whether this means just releasing the line from it or actually prying the entire clip off which can be a nightmare and will usually break them. Also show the factory headers unbolted and coming out and the new ones going in. Also, show the braces before and after removal.

This may be a great opportunity for you guys to make a video of this install and post it on YouTube.
