Yes, the savage CF cover will interest with the antenna. I bought it and it interfered with my Sirius radio. I ended up just having mine wrapped locally.

I had already had them many years so I just had a local shop repair them. I built a 6.3 stroker and upgraded to the 1 7/8 Texas speed at that time because I was boosted. Dont get me wrong, stainless is a good product but after comparing the two and the price I chose Texas speed

It’s a 5

You would hope that’s the case. I bought stainless works headers for my truck many years ago thinking I was paying top dollar for a quality product. One of the primary tubes blew out on me. I have since switched to Texas speed products which are very high quality at a more reasonable price.

After the 570 pull we realized one of the actuators was bleeding off boost. The car was already dialed in so we just replaced the actuator and left it as is. My guess it’s 600 wheel or so but I don’t have documentation on that so I just called it 570. I also now have the ethanol content up to...

Stock turbos are maxxed at 24 psi. I’m right there. Like 23 psi

Here is my other toy. 05 Sierra, boosted 6.3 with all the goodies.

I agree. I can feel the difference from the E 58 it was dynoed at and the E75 I’m at now. Unfortunately the stock turbos are maxxed out at this point.

I would assume the low pressure. The high pressure internals were all upgraded

The problem is E85. The stock system flows very well for running 85 but it does have its limitations. If this was an old CTS-V you would have had to do a full fuel system upgrade. I have a truck pushing over 700 wheel hp on a third gen LS. I had to run twin 340 fuel pumps and 1200 fuel...

Yes. I am maxxed out. I can run 85 but only in short bursts. I am trying to stick around 75

Very nice. Whats under the hood??

Typically a vintage car is recognized as being at least 25 years old.

Looks like a 55 under there🤷🏼‍♂️

Believe it or not. Out of boost it has a lot more pep. Shifts are very crisp and authoritative. In boost it pulls very strong up until redline. Very happy. The cams and the bow pipes give it a great sound too. I’ll post a video later.

I just recently sold my 70 nova SS. 496 BBC. Turbo 400 with manual reverse valve body. Great fun to drive. Prob 500 wheel horsepower at least. I love my CT4 Blackwing but there is nothing like an old school classic with big cubes!!

I have the A10 trans. The trans now has very firm/agressive shifts. At times chirping the 1-2 shift

The mods for this build include: Tapout stage 1 cam kit and valve springs, Tapout non- catted downpipes, Auto tech high volume HPFP internal kit, DSK flex fuel kit, Gigs ported throttle body, Tapout air box lid and green filters, Brisk plugs, Aeroforce scan gauges. The bulk of the cost is...

A big thanks to Tapout Tuning and Exodus Performance in Austin TX. The CT4 V Blackwing went on the rollers today. At just under E60 ceiling we managed a 570 whp and 600 wtq. The response and feel is next level!!!

Welcome. I knew once I read the title to this post you were a Texan!!🤘
