New Caprice - Discussion forums

Hey guys, I've been sitting on this Caprice for almost 8 years now and haven't done much to it or driven it but I've kind of been thinking giving it some love and doing some mods before I swap it for something else. It's a 2011 that I bought brand new in 2011. It's a 9C3 Detective model with the full center console and carpet/upholstery. It's only got 45k on the ticker and has always been garage kept. A local Chevy dealer who I've bought other cars and trucks from sold it to me when they first came out. I thought it was very interesting and the SS hadn't come out yet so I picked it up. Since then it's been just a weekend cruiser here and there.

I had a local shop do a tune and intake, they also swapped on the 20" Camaro wheels. They dyno'd it to a lousy 310 WHP. I doubt they tuned it and the Ram air intake sounds great, cleaned up the engine bay, but didn't do too much performance wise. They also did low profile electronic cutouts from DMH that leaked since Day 1. I see they have the old paper gaskets so I may try to swap them out for RTV but I'll likely just do an exhaust instead.

So I guess I'm really wanting to do the DOD delete and a cam to try and get some power out of this car because it just hasn't been the ball of fire I was expecting. A couple questions though:

Can I do the cam and DOD delete with the motor in the car? I don't mind pulling the front clip and radiator just wasn't sure if this was a giant PITA or if it wasn't too bad.

With a mild cam and DOD delete can I get anywhere near 400 WHP? I'm not wanting to mod the trans or converter at all, just looking for a reliable daily driver that pushes more horse than 310 at the wheels.

Also, for the White performance radio unlock do I need the BCM reprogrammed by a dealer or is it as simple as popping the silver box out and re-installing it?

And last but not least here's a pic of my beast:

For the radio upgrade just the silver box needs to be sent. Nothing with the BCM.

Looks NIce!!

Welcome! Very nice 9c3.

Can't help you with the cam but I'm sure others have done this on here. check out the engine section for ideas.

And as @smwalker said, just need to send the silver box.

Cam can be done with motor in car. Great looking car, plenty of mild cams out there that can do 400rw. Enjoy!

Note that when removing the silver box, be careful on the removal, there's a plastic connector that invariably gets broken when people are removing them from cars, rendering the box almost useless.

DOD can be done in the car, but it is a bit more hassle. Radiator out, but the condenser can be rotated out of the way, if you don't want to hassle with a vacuum and recharge after the work is done. Site search is your friend on that process.

Thanks for the replies guys!! I will be extra careful on the silver box removal. I'll start looking on YouTube this morning before I start.

Welcome to the group! See this link regarding removing the radio/silver box...

Quite a few people have provided tips and diagrams. That should help with your removal.

I used a 220 227 112+2 ? With bolt ons dynod right at 400whp with my g8 . Doesn't take a big cam to get there! Plenty of companies that make great cams that are stock stall friendly!

Thanks so much! I tried to search for a walk through on the CAM / DOD delete but couldn't find a Caprice based one. Do you know of one on here or elsewhere?

For the cam, spring, lifter, pushrod replacement I would just reference the ls1howto article on LS1 fbody heads/cam install (obviously double check any torque specs). For the DoD specific part replacments like valley cover and the like (regarding the actual parts required and such), G8board probably has some nice info. Hell, I think silversled here even had a fairly nice writeup. Enjoy!
