4.6L Cam Talk
I'm now in the process of getting together everything I need for my motor build.
I must thank both Pat from Steeda.ca and Scott from VT Engines for their assitance during this process. I'm seriously considering a Stage 2 cam. Anyone else running a stage 2 cam from any company? I am told it's quite streetable, but I'd like to hear some real life experiences. Thanks :) |
I was planning to run a set of crower stage 3 cams in my 4V motor.... but for a 2V motor the stage 2 VT cams are excellent, just remember to order the spring package at the same time :tup

As I mentioned when we spoke, the stage 2's are the way to go
|
K here is the Crower Stage #3 on this Nutso 01 Cobra my buddy is Tuning!
Damm need to host on our site check back. got though :tup |
All our camshaft grinds were designed for street driven applications. This is why our duration isn't overkill like some of the other companies. We did something different than any other company....... we kept duration moderate, but tightened the c/l on the cams. We are working on some new grinds (stage3's for both blower and n/a) that will be more strip/weekend warrior. :) All our profiles are designed in house by Jim.

K here you go!
Damm you have to http://www.rtmmotorsports.com/Cammed01Cobra1.wmv I does sound Sick! seriously! ba bahitty ba bahitty....Insane! Heard the VT Stage 2's too NICE! :tup I'll post the other on the 01 Post! |
Well, I finally made up my mind and went with the VT Stage II cams. Thanks to Scott and Jim for their great advice.
|
Been talking to Paul Meister,a few months back,and also have decided to go with the VT stage II's.I will be doing the purchace come close to spring.Just need to decide on a set of valve springs. :rolleyes:
I've got some good sound clips of the stage II's.They make the hairs on the back of my neck stand up!LOL!! :tup |
yeah the Stage 2's sound great, Mike needs to hurry up and host the damn vids :shakeit: Air care out hear will likely be a problem though

Nice :tup
Can't wait to hear !:rockwoot: LUMPITY LUMP,LUMPITY LUMP,LUMPITY LUMP!!! Camzzzzzzzzzzzzzzz! :biggrin: |
I also spoke to Pat and Paul and I too will be looking at some stage 2 heads and stage 2 cams but since the heads will be coming off I will also probably also put in a set of long tube headers..........does anyone know how this will effect emissions?????

I was actually takling to a mechanic yestaurday about the stage II's ,and emissions.He says it can be done.With a good tune it should be alright,but you are thinking of running long tubes,and installing ported heads,so the only way you will really know is when the time comes :confused: .
|
what would be the best cam for me, i drive it daily, ill take it to the track a few times, but i want a more agressive morelumpy idle and sound but still gaining power instead of over doing it and losing power.

Since we're on the topic, can anyone tell me what makes cams more "streetable"? I suppose ground for a lumpy but useable idle and low-end torque rather than just top-end power? Not too sure here..

I have read on the Mod Depot site that Stage II cams are not necessary unless the heads are ported. By the way this is my first post here.

From: Scott@VTEngines To: 1LOW03GT Posted: Tue Feb 1 2005 9:23 am Subject: Re: Hey! The cams will definately give you great improvements, even with stock heads. A customer of mine in FL recently put down 305rwhp with stock intake, stock heads, our stage2 na cams. THe porting will only add to the power and the range of the cams, but is NOT needed to gain power. The cams will add ~25rwhp peak to peak, and 35+ after 4000rpm. Thanks Scott _________________ Scott 519-245-1164 www.VTEngines.com And a higher up ford tech that i talk with quite frequently said the same.He stated that the PI heads flow very well compared to the previous years,aswell compared to the ol' 5.0L cylinder heads. So the descission would be based on how much hp you want to squeeze out of your 4.6 . :) |
How much more hp do Stage II cams get over Stage I. Will emmisions become a issue? I have zero problems replacing my cams, but will I need another tune with Stage I or II's.
|
Stage 1's don't need a tune,but stage 2's do to my understanding.
Emmisions....the ford tech i talk to said it can be done,but it could also depend on all the extra mods,like long tubes,h pipe,tune,and ects,.. The only true way to find out,is to do it.Most that have done the stage 2's,like the guys on modular depot,don't need the e test done from were most of them are located.(just assuming cause most haven't spoken about e tests :confused: ) |

Should see some nice gains :tup |

I had the VT Stage II Cams & Comp Springs installed about 2 weeks ago. I ended up gaining roughly 34 RWHP. The cams sound awesome at idle and sound even better at WOT. I'm still having a very small issue with the idle, but my tuner should be emailing me a new tune soon.
|
Nice gains! What's the rest of your combo? :chacha:

It isn't a bad idea to port heads for the stage 2's,it will give you a little more hp,but a the same time,the stage 2 cams can work well even if you don't do any porting.Some guys don't want to pull their heads of,and some do.

|
I think you can expect 330rwhp with Stage 2 Cams and Stage 2 Ported Heads
|
:confused: Let me correct myself,sence i just re read the post :bleh: .
I was just giving gains with only ported heads,which seems to be close to what Paul is saying if you add in the cams. :) Guys just adding in cams without the ported heads,and depending on the bolt ons,are usually hitting between 280 to 300 hp,and also depending on the tune. My bad,sometimes i read to fast. :banghead: |
Does anyone have sound clips of their cams??
|
|
I have a 3 different sound clips of the VT stage II's,but can't host them. :bleh:
They sound wicked with a nice exhaust set up. :tup |
It is all in the exhaust setup...you wont get that deep muscle sound with a borla/x pipe setup.
One of our customers with a 2V (top 5 in the world - 600rwhp on pump gas and runs 9's) has a Livernois Custom Grind, Prochamber, FLows and Dumps and it sounds like a big block...freakin insane You London guys must know him...Karlo with the purple 96 |
I need some one to host my vids as well
|
These guys will host anything...for FREE!
