I have a LS3 416 running on E85 and looking to add around a 300 shot direct port.

I believe I have the fuel system and injector to support the 300 dry shot.

what are the pros and cons between the two.

1 pro for the dry is I'm running a flex fuel sensor so my timing should auto correct itself if its not true E85 and the retard will pull from that. I will be using EFI live to tune with, am I thinking correctly on this.

also any tuners around the Houston area that are good with tuning nitrous on E-85 I hear its different than your normal race fuels

 

Dry hands down. Why E85 though? Is it a street car? What pump and injectors are you running?

 

Check out HP motorsports in Katy.

If you have the capability to tune for dry and the pump/injector to support it, it is great.

Otherwise I would stick with wet. Why not E85? You can get a tuneup just as consistent and run more timing than pump gas, not as "great" as race fuel, but alot cheaper in return. I'm assuming its a street strip car.

Yes this is a street/strip car, I'm running E85 because my CR is around 12.5

As for Injectors I have ID1000's and a aero motive fuel pump. I put down around 550hp unlocked

 

You should be good on injector. Can't say on the pump as you weren't very specific. You're planning on using the COS in EFI Live right?

 

yes that is correct on the COS the pump is a aeromotive A1000 pump

 

One of the best EFI Live Tuners is D3 Performance Engineering. They are familiar with the exact setup you are talking about. Silver Z06 with a big motor/ Big dry shot all controlled through the EFI Live. I would give them a call.
