Is this your cam?

[Kirk@VectorMotorsports]

Yes it is! You will have it Thursday.

Thats funny! I just PMd you about it. lol

[99-LS1-SS]

Looks awfully small....and it isn't even red.....

Lol!

[GeorgeInNePa]

Specs, man, we need specs!

[Steve]

ooooh... love me some juicy cam-goodness!

You are outta control! No mods for you! LOL!

[Mav]

Wow, very nice.

I am waiting to see the cam card. Kirk is keeping all of us in suspense! I would hate to see if you had a 4 cam Mustang Mike, you would go nutz thinking about all four of them cams! LMAO!

Very funny! My wife just said "4 cams!!!!?" (on a Mustang)......

I know. I'm going to pick this apart just figuring out what specs I would like on just 1 cam.... :)

Hey Kirk; Well, you succeeded in getting my attention (looks like a few others too!).

Would the cam in the picture have the following specs?

First Choice:
Comp Cams: 212/218…….0.558/0.563 115 LSA

My second choice at the moment would be the following.

Second Choice:
Livernois stage 1: 224/230 .581/.590 …… 114 LSA

[Panther 2]

And the Suspense builds!

[Featherburner]

If it aint .500 at the lobe you're playing with yourself. :devil:

[GRRRR8]

Kirk knows the goal, so I have a # in mind and I would "guess" close to .600

This is Charlies cam so it is a bit more aggressive. I think the 212/218 is a bit small for this application. If it were on a 112 + 4 you would make much better power with a excellent idle.

I generally have less lift on the exhaust than the intake on the cams we grind. I also have most every cam ground on a 112.

These new high speed E67 & E38 computers will handle keeping the car idling great (along with a few tuning tricks!).

The Katech cam we tune in the new Z06's is on a 110 and we still get them to idle excellent!

[Kirk@VectorMotorsports]

Pretty close.

230/238 .591"/.586" 112+4

This is going to be our Stage C cam :)

We are testing our 3rd different G8 cam this week. I have tweaked the cam a couple times. I think the final cam will be 226/234 .585"/.576" 112+4.

Thanks Kirk! :woohoo:

[Kirk@VectorMotorsports]

I think so. The 230/238 is for max power with a 3200+ converter necessary.

The 226/234 is going to be our standard G8 head/cam or cam only choice. A converter is not necessary, but would certainly help.

Why less lift on the exhaust?

[Kirk@VectorMotorsports]

Why less lift on the exhaust?

Because we have them ground on a less aggressive ramp rate than the intake. There is really no reason to have your exaust valve opening as fast as your intake. Plus it makes the valve train much more stable at high RPM.

Thanks for the quick response! A couple of things. 1- what's a 112 + 4? I know you're referring to the LSA, but not sure how you meant +4? 2- From what I've read so far re: cams, wouldn't a higher LSA be a little more torque friendly especially for a daily driven street only car? Looking forward to you answers as I'm sure a lot of others are too.

Makes sense if you know how it works.

1. 112+4 means we are grinding 4 degrees of advance into the camshaft. You then install the cam "straight up" meaning standard dot to dot.

2. Yes and no. having the cam ground on a 112 does lower mid & low RPM torque. But, advancing the cam 4 degrees gets it all back with very little impact to high RPM power under 7000 RPM.

Most tuners do not know how to tune a car on a 110-112 LSA so that is why you do not see them very often. Also, many people do not really get how LSA, ramp rates, asymmetrical lobes, overlap, lift & duration work together, so they tend to stay with very simple camshafts.

[GRRRR8]

I went on line last night and found similiar cams in GTOs/Vettes that were 6.0s also. Some in the Vettes were 615/605. So it must work as the videos showed these cars in the 10s all motor. A stock bottom end Camaro put 502 to the wheels with a similiar cam and head work.

Alright, so you get the benefit of a 112 LSA but since the cam's ramp is starting 4 degrees earlier you kinda get a 116 LSA but with better top end than a strictly 116 LSA cam would give you? Sorta playing the LSA against the advance to get a more optimum reponse overall? How come nobody else talks about this stuff Kirk. You must be an engineer or just have a really good understanding of cams and the effect of adjusting the various factors.

I was in camshaft (actually valve train) development for a living for quite a few years before I started my own company.

How much of a difference is there between the regular cam and the "Charlie Special"?

Yep, Kirk definitely knows his stuff. The last time I was down there, I told him I feel like I'm seeing the Wizard Of Oz when I come down to Vector Motorsports and see him. :)

The Vector Cam will be the next trip...... :)

I was wondering why I hadn't seen you log in on this post. I just couldn't believe that, here we were talking about cams, and where's Mike!

Whatever do you mean? I asking for the good of the forum, I'm sure others are wondering the same thing.

lol







;)

[GRRRR8]

Thats what I thought..............NOT! LOL!

[Kirk@VectorMotorsports]

Just more duration. He has a 3600 converter, so I figure we might as well use it!

[GRRRR8]

Thats why I let you choose it. To me cam decisions are all about combination of parts. For so many years with the old school 350s you would meet someone with a monster cam and 2.73 gears and a stock stall. When you tell them the car would have been faster with a 3.73 gear and a converter, they look at you shocked! I knew once I got the 3600 stall that the car would perform much better with a bigger cam. My plans changed a few times since the begining, but now that its not a daily driver, its all about max power!

[99-LS1-SS]

You are going to really struggle for traction on the street.

[GRRRR8]

It will just about always have ET Streets on it and if it doesnt it will have 285/35/19s on the back. I can still use traction control in a pinch.

Actually what we are doing is putting the intake centerline on 108. Thereby closing the intake valve a little soon to increase mid RPM cylinder pressure.

You have to love the Texas weather. I could probably get away with running a drag radial of some sort but the rain would be my downfall.

[GRRRR8]

I do not drive it in the rain anymore. I guess I would in am emergency, but other then that, it aint happenin!

So, I'm thinking if my car is still going to be a daily driver, should go with the 226/234 .585"/.576" 112+4 cam?


(other factors)

- gas mileage.....
- overall driveability & idle manners....

That would be a better choice for a DD. Not that mine couldnt be a DD, it will in nice weather, I just want to maximize the efforts of the combination.

Thanks for the advice Charlie & Kirk. I think the 226/234 .585"/.576" 112+4 Vector cam will be plenty for me.

Especially if I go the Vector Stage 2 route with that cam.




We are finalizing development on our new Vector Motorsports G8 GT camshaft / cylinder head packages.

We didn’t want to just jump into the market with a cam & head kit that was not actually proven in a G8.

The PSI springs we use have been extensively Spin Tron tested. I was in valve train development for two years. You will not find a more durable LSX street/strip spring.

We are offering 2 packages, Stage 1 and Stage 2.

Stage 1 –

VMS Custom Billet G8 Camshaft
PSI Valve Springs (We use these on our LS7 Z06 cam package with .650” lift at 7200 RPM)
Comp Cams Hardened Pushrods
ALL Necessary hardware to convert to a non DOD system (GMPP parts)
GM MLS Head Gaskets
ARP Head Bolts

Total Price Parts Only - $1395
Total Price Installed and Dyno Tuned (current VMS tune customers) - $3095
Total Price Installed and Dyno Tuned (new VMS tune customers) - $3295

Stage 2 –

All of the above parts
CNC Ported Cylinder Heads
Four Angle Intake Valve Job
Five Angle Exhaust Valve Job
Full Hand Blending of the Valve Jobs
Heads Decked to Raise Compression Ratio to 10.8:1
Upgraded - LS3 Hollow Stem Valves

Add $1250 to any of the above prices

We figure that since we have the heads off, why not port them!!

Final HP & TQ figures are coming soon.
We are looking for a local G8 to finish the development. We have two cars in process now.
Anybody willing will get VERY special pricing!

Any current / updated news on the RWHP & RWTQ numbers on the 226/234 .585"/.576" 112+4 cam?

[Got 8?]

Damn can't believe I missed this...

I've been doing too many other hobbies I guess. But that cam is what I had in mind when I started looking when I bought the car. Well...the Comp 232/238 but hey...who's counting ??? 230/232 was a little small for my tastes...LOL

I knew going with that "baby" hot cam wasn't enough. Hell I knew a guy that ran the LS1 hot cam in a 4.8 with nitrous and it ran pretty decent I guess...

Post up video when you run it at the track. I wanna see how it behaves if you can keep it hooked up. Better practice alot before game night, she should scream...LOL

Good luck Charlie...next time I head to Specs on 6 I may stop by...
