They might be out of stock of the st2 blower cams? I remember them saying their site sometimes takes the product offline when they are not in stock. I have the St2 blower cams but not NA.
Yea thats what i thought. I want cams just dont feel like buying stg1 or 2 n/a cams then getting my blower and having to switch to blower cams its a waste so i figure get blower cams first.
blower grinds do not have any "Scavenging" overlap like n/a grinds do, they are designed in mind to keep the valves open longer to allow more air into the cylinder, whereas n/a grinds overlap so that the engine sucks in more air via a process called "Scavenging" where the escaping exhaust gases help pull in more air.
i dont think you will gain much if anything going from stock to blower grinds without a blower, but as soon as you do get the blower, itll make it that much better.
This must be the case, 'cause I checked on Monday, and they weren't showing the stage II's.
What's the better of the two for a street/sometimes strip car with an 8 psi Vortech? I see the different lift and duration profiles.
Ok,
I am wondering, have you checked out aftermarket cams for a 4.6 from more than just VT? Just curious...
I really don't like how companies classify their cams... The Comp line of Cams especially the Comp 270 PI cam work well both N/A and in a SC application. Crower Stage 2 SC PI cam is almost identical in specs compared to the Comp 270 except the Crower cam has more lift.
I am using the Crower Stg 2 SC PI cam in my N/A application and I have no intentions of ever adding a SC. According to your post, it wouldn't make any more power than if it had stock cams, well...
My car with the plastic PI intake, auto transmission and IRS is making more power( about 20 RWHP ) than a car with similar engine specs( 5.0L Big-Bore ) as mine that has VT Stg 2 N/A cams, higher compression ratio and the Fox lake P51 intake and is in a 5 Spd manual mustang. The advantages in parts that my car has, is the bigger Crower Cams and better heads, everything else the mustang has the advantage...
In short, most 4.6 S/C cams will work in a N/A application and work quite well doing so...
"I made 468rwhp with stock cams then with Tim's cams I made 561rwhp. That was with a T-trim, ported heads, 15psi and a stock intake and stock exhaust manifolds. "
