Nice! Looking forward to doing mine.

Thanks!!!

Has great street manners and pulls like freight train!!!

Very nice. I just took my dod out an put 418 rwhp an 407.

Very nice!!

Do you have a stall for that cam?

Tainted,

It's own my list of next things to do for sure.
I have to settle down for awhile spending money on this car.
The little woman has lost her sense of humor.
Sleeping on the couch isn't like camping, no matter what your friends tell you!!!! LMAO

Thanks for all the positive comments guys......

How bad is the driveability right now without the stall?

Sorry edit reading this on a phone

The idle is set at 50 rpm over stock.
It's either 550 or 600 rpm
Even the gas mileage is tolerable @ 16/23 MPG.
I have no issues at all with street manners.

Suspension mods to make it hook up better and durability, torque converter & supercharger are my next things to do.
The cam selection was also planned around a supercharger down the road.

Brian has tuned a couple of my cars, he's an awesome guy.

He always goes the extra mile to see the job is done right.

That's the same mileage as my stock G8 GXP. Very nice improvement and F cylinder deactivation.

Honestly I didn't think I would still get this good of mileage.

Not bad numbers .... I can still get 24mpg when I drive sanely !!!

what exactly is done when you delete the DOD?

what exactly is done when you delete the DOD?

You remove the lifters, trays, cam, timing gears with non AFM parts, and tuning.

very nice numbers,specialy with a blower cam.

It will have a blower to go with cam down the road for sure.

what DoD delete options do we have? i know livernois has one. who else?

May be a stupid question and I'm not asking to start anything....

Seems like the G8 with similar mods to a 4th gen shows lower dyno numbers. Is it the drive train eating up hp? Maybe I'm just mistaken but seems like usually a heads/cam/intake full bolt-ons deal on a 4th gen is in the 440-450 rwhp range??

Yes, and I'm not to happy about it either!!! LOL

I've been told that the independent suspension, 20" wheels, 3.27 Camaro differential & A6 hurt my dyno numbers.

But, I still love the car and a Procharger will fix this issue in the next few months.

Not trying to say im a cam expert of anything but with a blower cam being alittle light on hp compard to a n/a cam. sounds right least till you through blower on it. Because of the way they set the over lap and lobe seperation.

Good Point!!!!

gearing.

usually 4th is a 1:1 ratio, but the G8 is a 1:1.15 ratio I beleive, hence lower numbers as well as additional drivetrain loss through the IRS

So basically what everyone is saying is that the engine itself still has as much hp potential, just the drivetrain is where the losses occur?

Every 6L80E I've seen dyno on a G8, Corvette, or gen5 Camaro eats ~60hp. You can set your watch to it.

You can rapidly find yourself all over the place with variables when it comes to these conversations. I make 426rwhp/415rwtq on a 218/230 cam with no head work and stock pulleys / intake manifold / gearing etc. Make of that what you will.

I also know my stock baseline was 294/313 and, oddly enough, that's 61hp down from the 355bhp number from the factory. I've got the 6L80E A6 so... imagine that.

I'm taking to the track in the next couple of weeks and then we'll really know what got.

355 bhp from factory is rated at the flywheel. So if the 6L80 / driveline is eating 60hp then your right where you should be. I would not get to caught up on dyno numbers as to many variables come into play.

All makes perfect sense. Thanks

Sorry guys im new to the Ls world ! What is DOD DELETE ? What dose it do? How is it done ? THANKS

F-bodies that make 440+ use a larger cam to get that and they definitely aren't doing it through an automatic on average.

A cam the size of the OPs with ported stock cathedral port heads through an auto in an f-body would make similar numbers if not a little lower.

Yep, like I said... basically dead on w/ a 60 hp drop.

There's nothing to worry about with a dyno as long as you have your baseline. All you should care about is the delta.

OP Here Again,

I decided to get a little more power out of the setup before I add boost.
Placed an order for 1 7/8" American Racing Headers with X-Pipe today.
I'm going back to the dyno after this mod is complete and will post new numbers accordingly.

You're going to like that, ARH is good kit. I believe the cats are better than what's on the SLP setup if nothing else, let alone that it will be a proper LTH. Should make for an excellent foundation for future mods.

I installed my new ARH headers and I'm thrilled!!!

I can't wait to get it to the dyno and I'll post new numbers afterwards.

Picked up a little more power with ARH headers.
415 WHP with no tune changes.

The wheels are heavy as hell on the G8's.. Ours has 18's with all season tires and they are a bear..

Our G8 bone stock is rated @ 361hp and ran a 13.6@103 and weighs 4000 lbs without driver..
My 02 T/A with a Lid and Catback though a M6 made 325rwhp and went 13.3@108mph and weighed a little over 3500lbs without driver..

The G8's make great power its just like everyone is saying the drivetrain, and weight that kills putting the power to the ground. I use to bitch about how heavy my Firebird was but now it feels so small after racing the G8..

Another thing you have to look at is that our G8 is tuned for 87 octane were my WS6 needed 93 octane..


On a side note if you do a aftermarket cam in the G8 could you tune it for 87 octane or once you do a new cam does it need to be 93??

You can do 87

Awesome numbers!

What does a DOD delete kit cost? I'm getting ready to do one myself.

1600 or so with cam and all hardware

Good deal, I'm probably going to order mine today or tomorrow.

There are guys making great power and good numbers running DOD. The new DOD lifters are vastly superior to the original ones. Although I had no issues, I had the original lifters swapped out at a dealer under warranty so I can get the new ones. Once I install my ported intake manifold and TB I will be close to 450rwhp with a DOD setup.

Just look at what rick has done on the G8 boards. I would keep my options open if I were you that is all i'm saying. Could save yourself quite a bit of money...

Yeti,

I agree you can make power with the DOD set-up but.............I don't regret getting all the crap that can go wrong out of my engine once and for all. LOL

I was seriously considering doing a DOD cam, but I'm 90% sure that I just had a lifter fail, so I'm going to swap it all out for the non-DOD stuff. I'm not overly worried about has mileage with the car, I just wish I had the money for heads and a stall at the same time.

Although some people are having good luck, the DOD lifters are not reliable and I personally would not keep DOD with any aftermarket cam. Spend it when you cam it or spend it later, you're probably going to spend the money on deleting it regardless. Don't cost yourself an aftermarket cam too by waiting until it fails.

It's a neat technology and I'd love the chance to run it in a modified engine reliably to see what we can really start doing with it, but IMO from the large number of failures we've seen in even stock applications the current lifters just aren't up to the standards I would hold them to were I going to recommend a DOD setup to customers.

OP Here

Finally made it to the track after dod delete work.

Ran 12.72 @ 111 MPH on street tires.

I know it can do better but for now I'm just happy to get into the 12's!!!

I finally made my goal of 420 WHP!!!

Thanks Rick..............your intake design is awesome!!!!!

Good Work OP!

As thrilled as I was last year hitting the 423 HP mark, of course I wanted more.

After a pass down the track at the end of last year, running 12.72, I felt based on the power I make and comparing to other G8's with similar mods it should be running better ET's.

Of course it couldn't be the driver. ...........LOL.

So after doing research on rotating mass of wheel & tire weight; it was time to buy the G8 some new shoes. I needed better tires and lighter wheels to hook better and free up power & torque.

So here is the rundown of what I changed to get more power as follows:

Old setup..........20"x 8" / 20"x 9" Camaro SS wheels with Michelin Pilot A/S tires.

New setup........18"x 9" / 18" x 10" D-Force wheels with Michelin Pilot Super Sport tires.

The rear Camaro rear weight is around 30 lbs. and the new D-Force rear wheels weight 18.9 lbs.

Now for the results!!!! Old Dyno 423 HP / 395 Torque

New Dyno 441 HP / 407 Torque

All tunes and Dyno runs by Brian Turner @ Dyno Tune Motor Sports.

The car hooks great on the street and throttle response has improved.

I know there will be questions so ask away......

In the mean time I'll try to get the grin off my face from my Dyno last Friday!!!!!
