[COTW 1/17/11]: "camroSS Stage III+ & Much More"... Davenport Motorsports
 
In March 2010 I ordered my new Camaro 2SS/RS A6. I picked up the car from my dealership on June 16, 2010.

Prior to picking up the car I had been in contact with Steve at Davenport Motorsports in Calgary Alberta, Canada and inquired about having headers, CAI and a custom tune done on the car when it arrived. Steve asked several questions of me and how I was planning to drive the car. He then explained several options and prices to me and I went ahead and made an appointment to have the work done.

I took the car to Davenport on July 5th 2010 and was introduced to Steve, he took me for a tour of the shop and introduced me to Namala, Shannon and Bryan. Again we had a discussion as to my expectations for the car before the work proceeded. They did a baseline dyno run and recorded stock RWHP and torque at 317.66 RWHP and 333.72 ft/lb. torque. After installing the headers, CAI and a custom tune the dyno results were 357.58 RWHP and 361.98 ft/lbs. of torque. The car had 600 miles on it at the time.

After returning home I took the car to the track just to see what it would do in the ľ mile. I had never been to a track before, and I never missed another track weekend for the rest of the season. Despite wheel hopping, no traction and a very poor driver, the car ran consistently in the low to mid 13ís all season depending on weather. Needless to say I was in need of more horsepower, suspension, tires and numerous upgrades to keep it all together. Once again I contacted Davenport and from August until the end of November 2010 Steve, Namala and I tossed around many, many ideas and came up with a plan for the car to suit my needs with consideration given to my budget. We essentially set up a 2 stage project plan to put together the car that I want over the course of this winter and next.

I was also fortunate to receive GM Litho #176 signed by Mike Judge and Team Camaro from the Oshawa Ontario build plant.

In mid-October the car went to Outlaw Collision in Medicine Hat, Alberta for painting. The GFX, sunroof, striping and sharks fin were removed, the car was prepped and I had the trunk, roof, hood and GFX painted and reassembled. Two red pin stripes were added to complete the process. The car was then taken to Calgary and put into storage at Davenport Motorsports storage facility.

I researched everything from the parts and prices to proper installation and shop rates and have found Davenport to be very competitive with any of the other high end performance shops out there. My experience in working with them has been very good, they are honest and upfront when it comes to recommending upgrades and donít hesitate to recommend not doing something if they donít feel itís a benefit even though that takes money out of their pocket. They are all professionals from the showroom counter right on through the shop. Like any trustworthy performance shop (Jannetty, LPE, SC2150, to mention but a few) the cost to do serious modifications is not cheap but you can expect, and receive, a superior product when completed. If youíre in Western Canada or the North Western U.S. these guys should be considered if and when you modify. I consider myself to be a friend of the company and definitely get treated as such. But I digressÖÖ


The guys at Davenport took my car into the shop on December 15th 2010 and began on the first stage of our 2 winter project. Iíve asked Namala from Davenport to take over from here and put up the pictures and details of the work being done this winter. Road tuning and final adjustments of course will have to wait until spring.

Hope you enjoy the thread. Please feel free to ask any questions about the build.

Best Regards: Bryan ( camroSS )

Look nice, the color is grate enjoy it, its one hell of a car.

Thanks for the kind words Bryan!


When Bryan came by the shop, the first time, we were under the impression that he was very pleased with his Camaro, and just wanted a little more power. He'd discussed his initial mods with Steve and we went ahead and made the changes.

As all Camaro's do, his car responded really well to the Stainless works long tube header/Rotofab/custom tune combo.

A few weeks later he dropped by and we had our twin turbo Z06 parked outside.

Well Bryan asked if he could go for a ride. BIG MISTAKE! :facepalm:

See, going for a ride in that is taking a huge hit on the go fast crack pipe! :confused0068:

Well one full throttle 2nd and 3rd gear pull and our friend here was hooked! :drool:

He got out of the Z06, walked in the shop and said, "I need a supercharger!"

Bryan left that day a convert to the religion of horspower! (I'm certain a few on this forum share in his beliefs) :sm0:

Well as our story continues you'll see that the supercharger wasn't enough for our new horsepower junkie. :D


His weekly 1/4 mile excursions continued and once a week our phone would ring with a "hey, maybe we should do this, and maybe we should do that". :)

Steve and I talked to Bryan about his goals and came up with a plan.

Bryan has asked me to continue on with this journal as Iíve been taking pictures and have better access to the car than him.

To be continued......

Here's the start.

Just getting it ready, white protective transportation film, then fender covers.

The old set up.

Intake, heads and front cover all removed. 6.2 ready and waiting for a big injection of power!

The old parts put aside out of the way so they won't get damaged.

Bryan: That intake sucking noise you keep hearing is your wallet...not the car.

Beautiful car and it sounds like it is in great hands...subscribed!

Gorgeous paint job. I absolutely love the look.

Davenport 01-05-2011 12:24 PM

We're porting the lower manifold on the TVS 2300.

Here are a few photo's that show the difference.

By porting the lower intake it now has the same rectangular shape as the heads, thus eliminating any flow restriction between the intake and heads. The benefit is less back pressure on the discharge side of the supercharger which allows it to produce the same volume of air to the cylinder with less boost and at a lower temperature.

Cool, and this is only a question, does the increased port size slow down the intake velocity, or is it a wash...I can certainly see where the charge would be cooler, less resistance... But does this also equate to less pressure...

I'm starting a twin turbo build, and wanting to know everything I can...

Thanks and this is a beautiful car...I love the paint scheme...

Hi, we saw the same boost levels as non ported intakes, in fact with the cnc heads, we also did not see a drop in boost level:)

Thanks Octane, and again, I am not questioning you guys knowledge, just wanting to learn, where is the boost measured. I guess my curiosity stems from wondering why Magnuson would shape their ports like that knowing there are probably no ports on any heads that match it...I guess maybe that gives the shops more options. Your work certainly makes sense to the eye though, nice porting job...

A few shot's of the LPE CNC'd LS3 Cylinder heads.

Brand new LS3 Castings, fully CNC'd, all ports hand sand rolled for final clean up, upgraded Ferrara dual valve springs, and titanium retainers.

I tried to take pictures of the ports but the camera wouldn't focus.:iono:

There would definetly be a velocity increase at the node where the air passes through the non ported intake into the ported head. The non ported intake would act as a choke or restrictor to the flow and would create a higher pressure upstream of the node. The flow is certainly more laminar and less turbulent after porting.

With regards to less pressure...If we agree that there is a temp drop (which we appear to) and volume (area of the chambers) of course is constant then;
(Pressure X Volume = Temperature) or P = T/V

Ex.1)
Temp @ 150F, T=150
Vol @ 3L (assumed), Vol=3

P=150/3
P=50

Ex.2)
Temp@ 140F, T=140
Vol @ 3L (assumed), Vol=3

P=140/3
P=46.6

These are hypothetical numbers but as you can see in the examples, buy reducing Temp, Pressure has to drop.

This is gonna be one wicked Machine.......subscribed~!!!!!

Sick paint job BTW!!
