Twin Turbos

[SSNYSTR]

Just wondering, I'm not really sure if you can or not. You can't keep your headers with turbos right? What about aftermarket exhaust? In the future I always wanted FI, but wasn't sure supercharger or twins. Twins just seem cooler to have, but you don't get the instant power like a supercharger and like I said I don't think you can keep headers.

Depends on kits, but most of the quality kits use stock manifolds or can use shorties. So you can sell your long tubes to get money back.

Axles, cat backs all work fine with most of the good systems.

The rear mount turbos, you can. But.....

If I would get turbos, I would want my car to still be loud. Are y'all cars are loud? Going from long tubes to stock manifolds or shorties would quiet it a good bit in my opinion?

Don't fall into the misconception of superchargers having quicker power than turbos, it's all about the setup. Example: my car with a 418 TVS2300 made great low end power pretty much from idle to 5200rpms switch to turbos specific for my set up & was making more power by 2500 rpms to 6800 rpms with 6lbs less boost than the supercharger. Just something to think about. I would call the guys at AGP & talk to Kevin great company & great turbo kit. If your wanting to keep the headers ECS is another great company for superchargers had one on my C7 & it

Loud is more the mufflers. You could run a straight 3" system with no mufflers after the turbos and it would be damn loud. Or some small bullet mufflers.

I run 3in straight pipes from the turbos back it's loud really loud in a good way! There's just something about a cam'd v8 chopping with turbos spooling. If you want louder I'm sure adding a pair of shorties & turn downs would make it stupid loud or cut outs so you can open & close the madness!

You have an exhaust clip of your car? I never thought about straight pipes. I currently have NoWeeds diverters(open headers) on my car and Borla ATAK for when they are closed. I love the loudness/deepness of the open headers. This would be for my 6th Gen when I get it so in sure shorties and NoWeeds with turbos would still be pretty loud.

6th Gen with turbos will be insane, if your talking about the SS with the LT1. Yes I have videos of the exhaust, I'm on thanksgiving vacation with the family but will try to post you something when I get home. There will probably be a slew of superchargers hit the market for the 6th gen based right off what's been done with the c7 already. All the turbo stuff I have seen for the new LT1 have been pretty much custom but I'm sure kits are soon to follow hopefully AGP!

Yes I'm talking about the LT1. I'm sure AGP will be soon. Take your time with the video.

Buy a 6th gen and send it to AGP and you can be the first.

LT1 and LT4 fuel delivery is going to be an issue. This is also why it will take some time to make E85 work properly on these engines. Advanced Modern Performance (AMP) was the first to make over 1000RWHP on a boost only Procharger F1X on a LT4 Z06 and that took some time to accomplish. Direct Injection is an entirely different animal and GM's ECU maps are much more complex on these engines.

The issue is NOT getting more air in to these engines, but getting enough fuel to support the higher horsepower applications and THEN not having the ECU be self limiting. If you think the tuner was important BEFORE, on a high HP LT1 or LT4 application, it is even MORE crucial.

590-610RWHP with centrifugal blower only (6-8psi)
Add methanol to combo and see 650RWHP

650-750RWHP with blower/cam (33% fuel pump lobe)/Headers/Methanol of course

Not to bad for a stock LT1 motor & fuel system I'm at 607rwhp on 8lbs no headers on 93 oct could probably lose 1.5 lbs with headers & keep the same power level or take the restrictior plate out with headers & be close to 700rwhp.

YEP that is good. I have seen 670 RWHP with STOCK headers and CAM using METH with an ECS setup on a C7 convertible LT1. This particular setup is running 9-10 PSI boost. Next logical step here would be to change cam and run aftermarket headers.

I have seen 736 RWHP with 765 TQ on an C7 Z06 with STOCK CAM with upgraded heads, ported STOCK SC E85 and Meth

In all these cases the STOCK fuel system is used.
