FWD Performance F-4 Cam

[mw6886]

Holy crap is all I can say. It is AWESOME. It makes power all the way to my adjusted redline, which is quite high. :)

Idle isn't that bad - I'm still pulling 13-15hg vacuum.

Kudos go out to FWDP and their research. Kudos to them also for their quick shipping! (More than I can say about other vendors, not pointing any fingers.. :) )

Thanks Cindy!

This is a cam for the 8 valve? This cam eliminates the roughly 5200 km top out of our power range?

[mw6886]

If you are talking about where the powerband is, and was, I would have to say that is going to differ for every car that is modified.

[overlordsshadow]

Ya I guess so.

[Bubba]

I have the F3 cam, haven't installed it yet. What's your set-up?

[glhs727]

Thanks! The f-4 is a really nice cam for a really modded car, and definitely can hit some rpm's. But at was pointed out every car will be slightly different.

BTW our F-5 custom billet cams (not regrinds) will be out next month, more to come on that.

Cindy

Wow, F4, F5....should I have went with a more radical cam since everything else I'm putting together is crazy?

[mw6886]

Dang! F-5? Should I have waited? Eh.. no better time than the present, I always say. :)

My car...

2.2 +40s on FWD billet rail w/AccuFab, 2 piece intake slightly ported opened up to 52mm TB, 52mm TB, ported exhaust manifold with 3" SV to 3" side exit exhaust, T3/T4 50trim in T3 housing Stage 2 .63 turbine , F-4 cam, stock head ported by me, Mishimoto intercooler with 2.5 piping, 94 523 trans w/3.5 FD, Revlok clutch, OmniPotent Blak-Trax posi, forged crank, T2 rods, .020 Mahle pistons, #4 cooling mod

Wow, is that it? Huh... well, went 12.509 on stock turbo with Mishimoto intercooler. 13.01 all day on S60 intercooler. Oh, and my own cal. :)

[Bubba]

Very similar set-up as mine with the exception of I'll be running a 2.5 and a big valve g-head from FWD perf.

[mw6886]

Oh, that 12.509 on stock turbo was also with a stock cam. With the F-4 I have installed at the recommended 116* installed centerline with an adjustable cam gear. I can tell you that with just the cam install the car runs stronger than it EVER has.

Looking forward to trying out your cal.:eyebrows:

Any dyno time?

When are you going to the track, is that the only part you changed?

[mw6886]

Well, unfortunately it is not the only thing I changed. So, to get a real feel for what kind of extra power I am making will be hard. But, I can say this - I was having some spool issues with my turbo before the cam, and now spooling isn't an issue.

Track time - April 14th. Dyno time - very money dependant. :)

Keith - let me know if you need some tweaking on that cal!

[turbovanman²]

LOL, thats always the case, you end up changing more stuff. :p

What else did you change?

[mw6886]

Well, the 12.5 was on a slightly ported head (not as much as it is now) stock cam, 1 piece intake, stock fuel rail, 523 with 3.77 gears, stock turbo. Almost all stock stuff.

Now, I have added the 2 piece, more porting, 3.5 FD gears, billet fuel rail, t3/t4 turbo etc.

I haven't been able to achieve the 12.5 again.. mostly 12.8 or .9 with the new turbo... I don't think it will be a problem now - shooting for low low 12s

[8valves]

Your gain in spool time is more attributed to the head changes and intake change rather than the cam. From what FWD's site specs the cam out at it should push spool time in a direct swap back about 500-700 rpms I'd imagine.

I'd like to see a graph of the cars power output, any chance you'll be at a dyno any time soon?

[mw6886]

Possibility of going to the dyno in the future, but nothing confirmed.
Maybe I can get that worked out..... :)

Without revealing your exact specs, can you give us some basic info on the F4 and soon to be... F5? Lift and duration? What springs need to be run?

[crazy1eye]

The F4 specs are on the website... http://www.fwdperformance.com/store/Product.asp?IDCatalog=78&ProductID=877

We just need to know the F5 :D

[mw6886]

282/276 duration at .006 tappett lift on the intake/exhaust
470/467 gross valve lift on the intake/exhaust
centerline 116


I can never get FWD links to go where they need to....

[glhs727]

We will be posting the F-5 cam specs when the cams are in stock and ready for sale. Until then, you'll just have to wait :D

I have been wanting to try the F3 cam, but I use the factory manifold modded. The overlap and duration on the F4 looks like it needs FWDs header to really get used. People have complained about larger cams for years with the POS log header setups, a real header opens a whole new world without reversion.

I just want to use the PT lifters, not a shimmed stock lifter. That requires the custom billet to get the lobe without a smaller base circle. Big $ there, but as our heads flow horrid I am looking forward to a cam that holds the cam open longer with the lower lift. Maybe I shouldn't build 4 cars at once and I would have one really nice car?

[Mr overkill]

bump kep the info coming

[1FastCSX289]

Uprgraded springs and followers needed?

[mw6886]

I'm running FM springs I got over 10 years ago. Supposedly similar to the Super60 springs. Just using regular rollers, and high RPM lifters.

You might want to find someone who can pressure test those springs.

Mine were "thought" to be okay, a stock spring has a seat pressure of 105 supposedly. Mine tested at only 66 psi of seat pressure. Can anyone say mass valve float?

[glhs875]

Yes, spring pressure checking is a very good idea. I will this time. I'm going with some Menegon spec springs but will still have them pressure checked. I was running MP 061 springs and ended up spitting a couple of rockers/ broke lifters and bent a valve stem spinning the engine to 7800rpm. Valve float can become a serious problem!!! The MP 061 springs seemed to be fine to around 7200rpm, but not much if any past that point. In my opinion the 8V valvetrain in in need of some help for high R's.

Well, I can tell you this. The last time I had the springs out was about 2 years ago. This was to swap them to a new head. Taking the stock springs out of a head is painless. Taking these springs out takes a some muscle and patience. So if that is a good indication of their pressure, I think they are OK for now. I don't spin a lot of RPMs anyhow, and the car certainly doesn't see daily driving.

We're still waiting....

[Stratman]

Hey Cindy,
I ran across this thread and am wondering (like everyone else) what the ETA might be on these new cams? I wish the specs were available on these to see if I need to stop looking for someone with new billets.


We will be posting the F-5 cam specs when the cams are in stock and ready for sale. Until then, you'll just have to wait :D

[glhs727]

all our stage 5 cams will be made with NEW BILLETS only. We are curently testing 3 different base circles. We should have them on the shelf in 4-6 weeks.
later,
Cindy

[Stratman]

I forgot to ask if these will be roller cams?

[glhs727]

All our performance cams are roller cams.

[10G OMNI]

F-5? been a while

[glhs727]

we are finishing the last bit of R&D, and should have these available before the end of the year.
