I have a modded c7 and I have considered going to a C8. What are the road blocks to getting to 800 whp in a C8? Fuel system? Programing? You need a drop in rod and piston set and a procharger or something to get there?

 

Same roadblock as always: $

No procharger is going to get you to 800whp. You're going to need twin turbos, upgraded clutches, probably axles and forged internals if you want it to last more than a day. You might also want to make sure you say a few prayers for your DCT. IT is doable but keep this in mind: 800whp in a C8 is going to feel like stock C7 Z06 power levels on the move. The gearing is that bad.

 

Don’t waste your money.
Ive decided to just enjoy mine the way it is. Way too costly and you’ll just ruin it’s value (most vette guys are weird and want them factory cuz there gonna be worth a gold mine)
this is why I kept my modded c7. Never get my 8 to its level so why bother.

 

Just buy a z06...

 

If you want BIG power in a C8, the Z06 is probably not the way to get it. Either spend $50,000 modding a Stingray or pony up for a ZR1. The Z06 is amazing but the engine does not allow for much of an upgrade path.

 

Well at least you live in a city where the best Phx metro C8 modder has a great shop.

I'm pretty sure with your C7 you already know him, but if not, check these on topic current threads.

You asked a direct question so I'll give you a direct answer without an opinion combined with actual knowledge.

You will need twin turbos, clutch, axles, fuel system, and tune. That's the basics. There will be more items to it than just that for a solid build. It adds up on this platform and quick. There has been a few platforms with this power on stock block but it would only be better to jump into a built short block especially if you beat on it a good amount. A built short block addresses other small issues over a drop in kit. So your true intentions would need to be discussed with a shop. Most higher HP builds as this I've seen lately and on a stock block just like the number and just like to have it for some quick burst when taken out on the weekends. Nothing wrong with that either. It's your car and your life. There has been a lot of advancements just in the last few months among the top shops that most don't even remotely know about. They just don't go around spilling it nor do they have the time more or less want to hear peoples gripes and constantly questioning what they have no clue about in performance and business. 95% of the builds of this caliber are not even on here nor want to be. So a great shop has so much to help you if serious.

Just be open to a big budget, how the shop will back/ support you, and you don't see a U-Haul behind a Hurst. One thing about this forum is very few supports or helps anyone here and you will find a boat load of criticism. I've seen better behavior and support on Honda forums. Every platform or car has their shortfalls in one way or another. Wish you the best in all ways.

 

Thanks for the info. I would probably do as much of the work myself as I could. I had my C7 motor build and installed plus supporting mods. I live in Arizona so for heat, I went max effort NA on the C7. I dont think I would be happy with a stock one. I vaguely remember people having tuning issues with the trans etc when it first came out. If 800 Whp cost 50k, there are a lot better platforms out there imo. I am having some health issues that will eventually force me to drive autos exclusively. My C7 is a manual.

 

Bear in mind that many procedures/operations on the C8 necessitate dropping the rear cradle and the entire engine/transaxle. Not for the faint of heart and well outside the scope of evan an above average DIYer. It's one of the reasons so many things are so expensive on this platform.

 

I got you. I rebuild my torque tube and had to pull apart the back half of the car. Also, the motor sits so low the motor on a c7 is a little more difficult too. You have to pull the steering rack among things. I’m sure I could do it.

 

There are some things that are just not straight up as it would seem. Pending how far you go with the C8. Such as the flywheel. It seems as you would just take the flywheel (which is fluid filled) off and just put it back in like a normal setup. There is a precise method/ measurement when placing back in. You have to know this. The clutch/ clutch discs when upgrading is another story in several different ways with specialty tools and measurements. Most don't understand the DCT at all. Understandably. It's new to the Vette world. Not new at all in the performance world. Most of the trial and errors have been solved or understood from the realm of the GTR, Audi R8, Lambo, and so on. My guy has worked on them all for years. Building some big power builds.

I've done some work on my own GTR DCT for years. Easier to get to for sure. Dropping the pan, valve body cleaning, valve alignment, and both filters which are just about the same on the C8. Just harder to get to some of them. A lot of misinformation on here from just not understanding. Such as "That's not what my GM mechanic said and I've known him for 10 years''. I'm just close to the right people and over time it pays. A GM mechanic or any basic shop is not cutting it. They know nothing. They don't build nothing, just replace a part that had a code and charge the same labor rate as a top notch shop. Wild for sure. Back then shops were more open than now. Now shops are just flat busy and make more money, understandably. By GM replacing every DCT with the smallest issue made people scared to death. They just wanted the DCT's back for testing from actual owner driven and more on the road. They did have issues where they weren't getting cleaned good enough upon being built and shim issues in first years while trying to push them out the door to quickly during the madness. Most all of them were just simple sensors, codes (which is part of their ridiculous programming), and valve bodies getting dirty due to their absolute ridiculous long term maintenance schedule. Especially when new. But don't ask anyone here that. "That's not what the manual says". Not like GM is going to admit or even change that literature. It has a diff inside of it in the same oil that will wear just as the gears will wear, especially when new and then over time. Funny how every single one I'm around has had no issues. They are built tight. Sometimes you just have to know this beyond a book. Prevent warranty work, not say it's under warranty. These DCT's are strong. Pretty impressed. Sorry about the rant. Tired of seeing so many complaining and talking down on this great car and finally help people from having issues that are preventable along with proper decisions. Too many suggestions from people that don’t even mod or been through the troubles of this platform. People more worried about their post count.

Edit: By the way if you've dropped a few engines before especially any Corvette and have a lift, and a elevating engine cart in which I wouldn't do without. It's not bad at all from anything else. But separating the DCT from the engine and the two piece cradle becomes a little more serious and even a engine hoist will be needed then too. Yeah just have someone do it. The way my car is it's only two hours. That's another story. The DCT can be dropped separate. One or two videos on YT to get an idea.

 

800 wheel the parts aren't the problem. Pick your turbo kit, ets, peitz, ours. Dodson clutch, fuel system, octane, pistons/rods, cam.

But the kicker is tuning. That is where it will come into play is having the right person tune it.

 

Thx for your knowledge buddy. Sounds like you definitely know your stuff. I pm’d you.

 

I feel like in these situations ... "where there is a will, there is a way". However, the way may not always be the easiest or efficient path to the end goal. That said, it can be the most rewarding. I have a Dodge Challenger that performs great on the road course. Are there other cars that coiuldve got to that point more cheaply? Yes. However, its always priceless when you have people come talk to you after track runs because of how surprised they are that my challenger did so well on the track.

In your case, getting to 800whp in a way that is sustainable may not be the easiest or cheapest vs buying a Z06 but it may (or may not) be rewarding depending if you pull it off.

 

Heck iF Emelia can get 1000 hp, so can you!

 

Keep in mind guys…….ya keep saying get a Z06…..
800 rwhp and a ZO6 are 2 completely different animals.
He could just do an E85 tune and bolt ons and be real close to Z06 territory.
