with stock heads, yes you would. ...so theoretically if the afr 205 + .040 gasket combo provides MORE ptv than a stock head/gasket, it would work. i was asking more for reassurance than anything.

 

Too bad a G5X3 on a 112 DOESNT require fly cutting. Who told you that ? I ran an X3 on a 112 for 2 years with ZERO problems shifting @ 6.8k rpms. There are TONS of people running the X3 on a 112 with no problems as well. Like I've said before, the x3 is an all around better cam, be it nitrous or NA because like patrick pointed out that it will produce better dynamic compression for more low-mid range AND it has a GREAT 7 degrees of split to compliment the nitrous.

 

Hi guys, there is 220 thou of valve drop with a milled, 59cc AFR and .040 cometics.


There is 200 thou of valve drop on a stock motor.

Any X series( G5, X1, X2, X3, X4, 111/112/114 excluding the xX ( which in most cases, thats install only here at the shop) will fit on a stock engine, 112 or 114. The X3 110 will not clear stock heads, but it will be close on the AFRs. You gain quite a bit of PTV with AFRs. If you are not sure, and want to know what your setup came in at, check it.

Let me know if I missed any questions, Ill keep an eye on this thread just in case

 

So the AFR 205's will work with the G5X3 on a 112 right out the box without any flycutting....While we're on this subject, have there been any other heads that have worked well with this cam, im basically wanting a good set of heads to work with the cam without having to do any flycutting

 

I have never touched my motor before, so assuming that I go with upgraded springs and pushrods, I will be absolutely fine with a G5X3 on a 112? Absolutely fine meaning it will require no flycutting and there will be no damage done to the motor.

I will be using this cam (if possible) with intentions of running it cam only for quite some time, and then stepping up to some AFR 205cc heads. I can do that with no issues, correct? What size chamber would be optimum for my intentions?

 

I dont have clearance numbers for any other heads, but I hope to change that soon.

No flycutting on stock heads, or the AFRs. If you pick a set of stock castings that are ported and milled with big valves, that will NOT work. AFRs only. ETs or Patriots, darts, ect- like I said, Im not sure. ET makes a good head, I just have not had any of their stuff on my dyno yet.


Yessir, no issues what so ever.

The 59cc AFRs with .040 cometics work very well. I have may dyno sheets up in our gallery at www.LGMotorsports.com that you can look at. Most are labeled

Thanks

Louis

 

Thanks for the updates Lou. I am considering the G5X3 for my car. Good to know that flycutting isn't required with stock heads.

 

I can't wait to get my X3 cam and also I can't wait to get my FAST 90mm intake ported either.

 

Thanks for clearing that up louis!

 

I am running AFR 205 milled to 60cc and a G5X2 @ 112. I am running a .045 gasket.

I like the G5X3 @ 112 as all of LG's cams make good power.

Louis - Just checking, but I thought that the AFR 205 heads would need to be flycut with a G5X3 @ 112? I know a bunch of guys that needed to flycut. Now I am thinking maybe they did not have to do it, but just did to make sure.

Please advise as I may get a G5X3 @ 112.

Sweet....Y'all sure are making some serious power with your cams as I can see from the dyno results Once I get some money set aside, you may be getting a call from me

 

I would also be intrested in the answer to this also as I have a set of AFR 205's milled to 60cc. The motor is currently on the engine stand and I am looking for a cam for it.

 

No flycutting necessary with AFRs at either 59 or 60 cc, or anything larger, say 61-72cc. The X3-112 will fit just fine

Many people flycut for 2 reasons- more clearance, and the slim chance they may want to go with a larger cam down the road, and do not want to pull the heads back off to flycut

Louis

 

Thank you for the clarification.

Hey Louis, just curious......I have the G5X3 with AFR 205's milled to 59 cc and Sean Burt had to flycut my pistons. He said there wouldn't be enough clearance if he didn't. Whatever the reason, my pistons were flycutt, so its odd to hear that flycutting isn't necessary. I wasn't a big fan of the idea of having my pistons cut. Just wondering why I needed to then, (3/31/06) and now its not necessary on AFR 205 59 cc G5X3 cam. I am on a 114 LSA if it matters?

 

Damn... very intersting thread as I am about to purchase a G5x3 on a 111.5 lsa from a good friend of mine for the stock head application... I need to get the cam card on that one and make sure the p to v clearance is sufficient etc...

 

Damn guys, your all pretty much asking the same questions i was wanting to know too, Thanks for all the help Louis, ive definently made my mind up on the G5X3.

 

I bought a x3 and had tsp do a cnc on my heads and install 2.04 intake valves and
I have yet to dyno the car(02 z06),BUT it's definetly the way to go I don't know about
clearances but it will turn up and pull like a beast.The sound is simply amazing with longtubes and no cats with b b bullets.No regrets at all.

 

Louis, not to beat a dead horse.....

AFR 59cc chamber/.040 Cometic/G5X3/114lsa

what are we looking at(ballpark) as far as clearances are concerned.....

I think the rule of thumb is .080 exhaust/ .100 intake???

TIA

 

Doug- We flycut the majority of our installs for a few reasons even though it isnt necessary. They will clear fine, but you have to remember, the volume of work we do, we have to idiot-proof the installs so the customer can bang the 3-2 miss-shift and not tap any valves at 8500 . If we didnt, that one customer would bend a valve or 8. Most people never have that issue, and the DIY Guy doing stuff at home knows what he is working on.

I will never turn anyone away from flycutting, and lets keep in mind that most of the time its necessary, just not with the combos everyone is asking about

Wavrdr- this is a very common combo as you probably know. Rule of thumb is .055-.060 min. on the intake (thats close), and 80-100 on the exhaust. The more the merrier. With that setup (X3/114, 59cc AFRs and cometics) You are looking at ~ 80I/130E. Everyones setup will vary, but thats been the number.

Louis
