ok so my car is tore down right now and i know somebody with a brand new g5x3 for sale just tryin to figure out how streetable this cam would be and if it would be good to use with the ported Ls1 heads that are already on my car. any info will help...

 

well, i can tell you it will make good power with supporting mods like springs, pushrods, ls6 intake or fast, 4.10's or 3.42's and a stall....and streetable all depends on you! i can dd mt car if i wanted to and its a 240's cam. it all depends on what you think driveabilty is

 

driveability is purely subjective. if you have friends with cammed lsx's go ride along with them and see if you can drive them. some people can live with a huge 240's cam idling off its ***, others want nothing more than a high 220s/low 230s. you need experience with each to know what you will have to live with. is your car an A4 or M6? that will defintely help define what will work for you. also, what gears do you have?

answer these to help you with that:
1.) what are your goals for the car
-track?
-dyno #s?
2.) how do you want the car to drive? do you want low end power, or can you do without that?

ill go see if i can dig up the specs on that cam and get back to you, as well as some dyno sheets of it too. im bored so youre in luck lol.

 

my car has the ls6 intake,pushrods, and 4.10's already. it is suppose to have a custom 224 cam in the car now but i dont know for sure because i was told it had aftermarket springs in it too but when it was tore down last week we discovered stock springs. I'll be gettin new springs and pushrods and may switch to a fast too. the car is only goin to be driven about 2 days a week

 

i was "told" the car dynoed at 419/410 before i got it.. and i'm tryin to just make some more power. The car is by far not slow now and does feel like its got over 400hp but it's tore apart now with a blown head gasket and i figure since its apart might as well make it a little better. the car may get to the track 2 times a year not much more i'm just mainly looking for some more excitement out of it...

 

witha m6 yor\ur going to need a good clutch cus the second you find out you new found power you will destory your stocker. and if it had a cam in it before...youll prolly be able to hear it. if you do go the big cam route thats cool and if you get a really good deal thats a + but i think theres better cams then that one

 

220's cam and 400 hp do not get along unless there are some heads involved....+ stock springs...id say no, my car felt really fast with just a tune and boltons. if your car has a cam and its 400hp +, you would not be double thinking it has a cam...there are not many ppl on stock heads and 220's cams getting close to that with them torq numbers

 

i have the ls7 clutch. if i get the cam it will be for cheap. I'm not really looking for the biggest cam just something better than what i have. you can tell mine has a small cam just listening to it but i have called the shop that did the cam job and all they will tell me is that it is 224/224 they say they dont know anything else about it and i would just like to have a cam i know more about and my tuner will know more about.

 

well g5x3 is a big cam, if i were you id go to patric g or get a custom grind that cam is not worth it imo

 

ok so heres what i got: specs are 23x/24x .600"/.610" on 110, 112, or 114 LSA. i found the exact specs(someone had it cam doctored) but since LG doesnt list them on their site, i wont here. they even hold it to a 2xx/2xx but i thought id give you a little idea. if you want the exact specs, ask them, and i would assume theyd tell you. on to the dyno sheets.....

ok so i got a few different ones just for comparisons sake:
#1

...cam only through a 6 speed (9" w/ 4.11s) lot more torque than i thought it would be. pretty damn good numbers for just cleaned up 241's.

#2
https://ls1tech.com/forums/dynamomet...5x3-new-s.html
...FAST, stock heads, g5x3 making 420/378 through a stalled auto; again pretty good.

#3
https://ls1tech.com/forums/dynamomet...e-results.html
...real good numbers here. 447/411 with some LS6 heads, and through the LS6 intake even.

hope that helps

 

maybe a 224ish cam wont, but something like the TSP 228R will easily make 400rwhp and damn near the same torque cam only.

 

wow most ppl i kno with th g5x3 cam are lower numbers loke 400's but it seems this cam like the heads, and can put down some torq

 

thanks for the info i'm goin to talk to my mechanic tomorrow and see what he thinks would be best for the car before i decide what i should buy.

 

the specs are .600 .610 236 242 have one myself.

 

Very. The 114LSA version drives better then the 112 imo.

 

Need to find out if its the G5x3 on a 112 or on a 114. Fitting a 112 with stock heads and not cutting valve reliefs would be very questionable.

 

i just got up with the guy and he said it was the 112. i've thought about finding some ls6 heads and gettin them ported would that be better..(i'm new to this)

 

Stock heads are very close with the 112. Some people make it, some dont.

I have the 114 version and daily drive it, but I have TFS heads ect...

 

If your ported heads have been milled, you will probably fall short on safe Piston to Valve Clearance.

Since the heads are coming off anyway, now is the time to cut the pistons for extra clearance. I'm guessing if you blew a gasket, they will at least be milled for cleanup. You may want to cc the heads to see if they were previously milled. Remove too much and you'll definitely have PTV issues.

Also, 420/410 sounds right on par for a 224 cam with ported heads.

 

the heads have been milled before and may be warped right now i will know tomorrow about them. thats another reason why i'm thinkin about gettin ls6 heads.
