Default E85? VVT/AFM delete?

Looking to start modding my C7. I just sold a 1200whp single turbo 5th gen Camaro. I am not wanting to go as crazy on the C7 but I want 900whp. Plans are an F1a Pro-Charger, cam, ported heads, full exhaust and E85. I can't find anything on the internet about running E85 on a C7 and how much power you will be able to make on it with a different cam. I am wanting to delete the AFM/VVT. If anyone can lead me in a direction on where to buy and who to call let me know. Thanks!

You won't find much on E85 on the C7 because the fuel system can't support it. (injector flow insufficient)

We have an AFM delete valley cover in the works.

Comp Cams VVT limiter for the L92 works on the LT1.

Jason, will the LS9 cam spockets work on the LT1 if I were to put a 3 bolt style cam? That way the VVT is completely out. E85 will not work even with adding lobes on the cam for fueling?

As far as I know, there is not a front engine cover that will allow you to delete the VVT. You can just get your cam spec'd accordingly, and zero out the VVT in the calibration.

Noted. Just saw they are different covers. Damn this new stuff ha ha.

I was told by a Delphi engineer that works with that particular fuel pump that changing the cam lobe is a big no-no.

Pretty sure they are changing the cam lobe, I guess time will tell how it holds up.

Yes, changing the cam lobe.

Other ways of doing it are supplemental fuel systems like Lingenfelter's PADI (Port Assisted Direct Injection) or wet nitrous systems.

Very excited to see you pushing the limits. Always quality builds from the "Stangkilr" camp.

Thank you! Looking forward to dealing with you guys on a blower. It should be a fun year. Just looking at the engine I see a bunch of stuff I can hide.

Ordered a cam through Allan Futral today. Going to retain the VVT and delete the DOD.

enlarging the cam lobe puts additional stress on the piston and spring inside the HPFP which will cause it to wear out faster. e85 can be done, just falls into knowing how to do math and how it relates to the injection timing tables. There are some flow rate changes that would have to be made to the injector scaling to go with this as well as it is not a simple put a number in and wing it approach. It will not support the blower on corn however.

Its nice to see someone like "stangkilr" push the C7 on E85 just to see what happens. E85 is a very dominate fuel in the midwest, and northern area obviously. One would be willing to bet a lot of people will follow this build because of that.

When we were already developing our supercharger kit, making dyno pulls, a lot of people on the internet said that the factory HPFP wouldn't support a supercharger with the factory cam. And that has long since been proven to be false. Hopefully that turns out to be the same with the cam lobe / FP correlation.

Surly it puts more stress on the pumps spring, and isn't advised. However is that really much different then asking the GM engineer if the stock short block should be living to the 1000+ rwhp levels currently being displayed?

Hot Rodding at its finest, people pushing factory parts to the limits, finding the limit, then developing a solution to move forward.

If the lt1 follows suit like the LNF, it will love the corn in terms of letting loose on the timing tables. You may run into a misfire issue at "normal DI lambda" just an FYI. Bolt ons and cam should be peachy on corn, again, if setup right.
