GREAT cam for a street car.

It will lope, and yet be docile enough for a daily driver. One of the best "does everything well" cams, and that's exactly what you're looking for.

The G5X3 is more aggressive, will have more lope, and a higher powerband range compared to the F13, but with a good tune, still tolerable on the street for most people.

 

Y2K, your car sounds awesome Every time I watch/hear a cam vid, I want one.. BTW EG, as always, nice clip!

 

Thanks! You missed out on the Madness Mod Party 2 weeks ago when I did Tom's car.

 

Does anyone here have the f13? Especially anyone in the VA, MD, NC area? I really like this cam but i am worried that I'll wish i had gone slightly more agressive.

 

Here is my TA with a Comp 228/230 571/573 112lsa. http://www.youtube.com/watch?v=UCM2wqutXS8

 

Last month I did a head/cam swap. I installed a Comp Cam 228/232 .588/.595 111+1 I did TSP new PRC stage 2.5 5.3 head with the smaller 220 cc intake runner with a 2.04 intake valves. I like the way the car sounds and it drives fine but the cam shakes the whole car and sometimes it gets to shaking pretty good. Jason at TSP did the tune and I am happy with the tune as it put down 432 rwhp and 400 rwtq. It runs really hard and at about 4000 rpm things really happen quick. However, I am tired of the shaking and ordered a new cam today from TSP to calm it down. After talking to forum members Switchbarrel and Ikester and then Jason at TSP I ordered a 224/228 .581/.588 114+2. My first cam has +8* of overlap and the new cam will have
-2*. That is a big difference. I will still have a little lope and good performance but should also get rid of the shaking. I have had race cars in the past but I don't want this car to behave like one at idle, just when I get in the gas!

 

Not to Hijack but EG, what else was added to that G5x4 Cam? That thing sounds insane!!! Just what I am looking for

 

Not to rain on your parade but this makes no sense whatsovever.

 

Dual snorkle intake, LG longtubes, x-pipe, no cats, PRC springs, titanium retainers, chrome moly pushrods, LS2 timing chain, etc. - all the usual stuff.

Tom did it right - full bolt-ons then a cam

Cat backs are Corsas (I think - ask Tom on that)

 

Y2K, your car sounds crazy. I actually have a brand new F13 on a 112lsa that im planning on having installed in a month, but now hearing your car im thinking if i should go your rout. I know it's subjective but is it tolerable for a DD? Dont mean to hijack thread but its relavent

 

See for yourself and you be the judge. This was BEFORE it was tuned, BTW...

 

Very nice! Thanks EG

 

Overlap is the key attribute to what defines a cam's manners.

Big overlap = badass idle, loud, more shake, top end (high rpm) powerband.
Low or neg overlap = sedate idle, good manners, lower rpm powerband.


Like the thread starter here, it seems most everyone wants the wicked idle, with little or no other sacrifices. Both can't happen. Some sacrifices must be made, either for practicality, or willingness to put up with a little loss of normal drivability. Good street manners, and low rpm usability will inherently suffer the more radical the cam sounds.

Everyone has their own idea of the best compromise. I think (in this case), your old cam would be almost ideal for what most people really want...noticible lope, a little shake, and yet pretty good overall street manners. 8* overlap isn't that much...but obviously, you wanted it even more tame than that (not faulting you, everyone has their own preference).

My little G5X4 has +20* overlap, and I love the shake and non-subtlety of it. That's what I wanted.

For black98c5:

My honest recommendation would be to keep and install your F13...I think you'll love it. For most people, I think the X4 would be too much for the street and daily driving. I have a high tolerance for bad manners, I knew what I was in for when I chose this cam.
Don't read that as disappointed or overwhelmed, I'm certainly not, I'm just keeping in mind what I think many of you are really asking for. Although the video shows the car can be driven sedately and in traffic, it really has changed the dynamics of the car, I did have to learn how to drive it all over again, and basically, it is loud, rude, and obnoxious. I love how the car sounds now too, but to be honest, I'm not too sure the local PD will agree with me. I'm seriously considering switching to a quieter exhaust before I get written up.

From a practicality standpoint, this particular cam (X4) will pull to well over 7000 rpm. On a stock engine, with limiting factors such as connecting rod bolts and rocker arms,etc...you'd be unwise to even find out where this cam peaks. I'll probably (against the advice of half the world) set my rev limit at 7k. If I blow the **** up, then 402 shortblock here I come. I'll have no one to blame but myself, but again...that's not something I'd advise or recommend to anyone.

My feelings is a good ballpark for a street "all purpose" cam would be in the 224-232 duration range....230-240 for an aggressive but still tolerable street cam, and (like mine) 240+ for the lunatic fringe.
That's assuming a stock size engine. Bigger cube motors can handle a lot more duration.

I researched everything I could read about cams for 2 years before I finally made up my mind. I'd advise everyone to do the same research before choosing a cam. Read and learn as much as you can, and don't buy "just because it sounds cool" in a video. By all means, get a cam, but be realistic in how wild or mild you really want it.

 

GHL catback.

UD pulley too.

 

i posted this website a while back. it has just about every sized cam you could want to hear. WWW.LS1SOUNDS.COM , on the left side of the page you will see the word, "camshafts" , click on that and you will find all kinds of sound clips on the right. just double click the cam size you want to hear on the right side of the page. hope this helps.

Brian,

 

I tried to make it over, but was out of state. One of these day's I would like to discuss h/c, lt's, gears, t/c, pulley, and intake for my 04 A4. The pics of the Madness party looked like a fun time was had by all

 

Y2K, thanks for breaking it down like that. I will go forth with my H/C install with the F13 112lsa and see how it does. I mean thats not a bad starting point i guess. You have your hands full with that car now for sure.....just awesome!

 

Black85c5,
make sure you let me know what you think of the F13 because that is my prime candidate as of now. Thanks

 

no problem

 

You will want to stay around a 114lsa with an A4 with stock convertor. I have a '98 A4 with a G5x3 and a 3600 stall with a 114lsa and a '01 Z06 MN6 with the G5X2 with a 109lsa. Big difference in the idle lope. 109 is more choppy than the 114. The stock convertor is your limiting factor in your cam selection IMO. Guys with a a smaller lsa are running six speeds or higher stall convertors.
