g5 cam specs

Re: g5 cam specs There will be NO miracle cams for a huge variety of configurations. Several cams in the 228-232 duration at .050 have made numbers recently that make people sit up and take notice. Everyone wants to stare at the peak numbers.
I made 396 rwhp with a HOTCAM and stock heads. Was it really a fast car? Not really. It sure was a pain in the *** (in my opinion) to drive on the street without programming.
Now Ive got a car that with some really fancy heads only makes "406 rwhp". I think its going to be a screaming fast car.
With any of these cams, look at the results in a configuration thats applicable (not a dual exhaust long tube vette for instance if you are running a MAC header F-body), and look over the entire power curve. MMS's 229vWhatever cam for instance, gives up loads of torque <4000 for the big numbers up top. I suspect that the G5 cam will turn out to do the same.
To enjoy your car the most, where do you need the power? This is a VERY important question. Very few of the folks on this board need all the power 5000+ rpm.
I suspect the G5 cam is like a 228/231 or so on a 113 with some lobes similar to the XE. I'll also bet that really nice longtube headers make up for alot of the low end issues that the cam brings.
But how many people here really need a 228/231 "ish" cam that really does beat the valvetrain around?

Re: g5 cam specs My only issue with the G5 is even after emailng LG and asking if it will pass the sniffer test and PCM scan emission test, all I can get is: We like to think it would.
Not exactly a concrete answer to go betting about $1500+ worth of cam and install on...
Can anyone tell me if the G5 shows a lot of misfire codes at idle without tuning?

Re: g5 cam specs The cam I purchase from L. G. has not had any misfire codes associated with idling, but the PCM was suppose to have been custom tune. I assume it was. I have driven the car for about 600 hundred miles. However, I was disappointed that my car did not idle any better than it did. They could have let the car idle for thirty or fourty minutes and let the PCM learn the new setup as I was told. For the funds I paid, it seems it was the least they could have done. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

Re: g5 cam specs a) its not that big.
b) whats the big deal? its Lou's decision. if you dont like the way he runs things, then buy something else. the G5 make good power....especially with stock heads, but all purchases are up to the customer.

Re: g5 cam specs I also don't think any companies would copy the idea if he let out the specs...look at the hammer cam, T1, B1, etc, everyone relates that to MTI, and the Comp Grind..thats COMP CAMS, and then the thunder cam...thats THUNDER RACING...then you have GTP cams, etc...and then there is the G5 cam, and we would relate that to LG MOTORSPORTS...its all very simple... <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

You LS1 rookie! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
When MTI had just finished testing and development of the T1/B1 cams, we kept the specs secret for at least a month. I had the first 346ci LS1 car to pull over 400 rwhp back then. People also said that 112 LSA cams would be downright nasty for a daily-driven car, and many "experts" told me not to go with 112 LSA. Got to remember, this was back in 99 <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> .
Well, when we finally got around to releasing the specs (they did tell the people who bought the cams, but not until they bought them), several shops started copying them. Some of the shops even went as far as selling them as "T1" and "B1" cams by name. FYI, "T1" = Tony1 and "B1" = Brooke1 and we were both MTI customers.
Funny huh?
Now, as for copying the G5, I doubt that will be an issue this late in the game. There are quite a few cams out there that produce excellent results, and its not really that much of a testing/development criteria when it comes to designing cams for a stock cube 346ci LS1 anymore. Back then, 221/221 was considered "big" haha.

Re: g5 cam specs Do they not disclose the specs to the customer if you purchase the cam? That would mean that you have no way to degree the cam if you wanted to do so. "Secret" cam specs are all well and good I suppose, but I think once you purchase the cam, you're entitled to all the specs.

Re: g5 cam specs I'm just full of afterthoughts today... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Reminds me of the 1st aftermarket cam I bought for my '98... I won't mention the vendor, but when I ordered it all I initially got were the .050 duration numbers, the lift, and the lsa. It took a major effort on my part to get a copy of the full specs, and that ended up being in the form of a bunch of scribbling on a piece of paper emailed to me after it had been faxed to someone else...

Re: g5 cam specs Thats interesting Tony, I didn't know they did that...well I hope G5 will eventually release the specs, it has been making some good power for everyone...I want to do heads soon, but while I'm in there, I want to consider stepping up the cam from my little cam which I currently have..its considered the "baby nuts" cam by friends...its a Comp Grind...222/222 .563/.563 112lsa...hmmm looks familar to another sort of cam out there.. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

easy huh.

Re: g5 cam specs Who makes the X-ER 226 grind, and what are the full specs on it, sounds like a nice cam...I plan on either procharging the car in the future or spraying it, both options with forged internals of course... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Comps lobe number is 3723 for that lobe profile.
Get it on a 114 or a 112 l/s with 4 degrees of advance ground into it.
Most any shop can get it for you with that info.
(In repsonse to the G5 cam owners impressions from an earlier post in this thread)
Having a cam that had idle probs and SES lights would suck. Keeping the duration in a "medium" range to avoid all that hassle sounds like the way to go.... to me.

Re: g5 cam specs gary....the point of the programming is to eliminate ALL issues with an aftermarket cam. when you do it...stay with it till your COMPLETELY happy. no point for you to hate your new cam, and it wont say much about a shop that wont take care of its customers.

Re: g5 cam specs Anyone notice the 2002 Z06 Cam had more Intake Duration than Exhaust?
That could be the only thing new that we haven't see a lot of in the past. or might be considered different or secret..?

Re: g5 cam specs the newer LS6 cam has more on the intake side to take full advantage of its LS6 intake. IN MODERATION (i.e. the very small duration of that cam as a whole), this works, however, when you get up around 220+, you are wasting energy. you can get all the flow you want out of the exhaust side of the motor...so in theory (with complimentry intake flow) BIG exhaust flow in the head combined with big duration exhaust side and good headers/catback...you should make more power. Single duration cams have better idle characteristics, however.

Re: g5 cam specs I had custom programming done for my current cam and I still got a SES light, I'm gonna see if I can get someones A-tap and see what the code is being thrown for...probably 02's or random misfire...

Looks to me like they pumped up the exhaust duration a lot to make up for the restrictive exhaust manifolds. This resulted in a "big 14 degree" split in the duration times, so they GM cranked up the LSA to 117.5 to get this thing to idle/pass emissions etc. Or am I missing something? Cause this sure don't look like a typical set of numbers for an LS1/LS6 cam.
