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!

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?

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

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

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.

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?

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.
