dev 3 or 5cam question for brendan

[blwneb]

hi brendan i will be running this setup , EBXR6 4L, auto, electronic shift kit, 3.45lsd, motorvator extracters, 2.5inch mandrel exh with res, unichip, capa stage2 9psi powerdyne kit, 2 12inch davies craig thermos, this setup running bp ultimate and nulon prostrength octane boost, it is running a standard xr6cam, i want to put in a dev3 or dev 5 cam, what cam do you think i should use, and what power could you estimate i could produce.

[loxxr6]

For the brief period of time I had the dev5 cam I was advised not to use it for a turbo setup. I'd be looking at getting a "turbo" cam, one suited to the characteristics of a forced induction engine.

JMM offer a turbo kit, see if they can use one of their turbo grinds(if they have one...I don't remember seeing info on their kits directly online).

[blwneb]

I remeber the red eb that was supercharged what cam did that have in it.

[loxxr6]

The site only has the red EB as Dev 5'd.

PM Casper as he spends a bit of time down their way. He might know.

[Casper]

No idea, Dev 5 I think

JMM have 2 different Turbo Cams available, depending on what your needs are.They are called the T1 and T2 cams. And there is the Godfather of the turbo cams, but I don't think JMM have released it yet.

As for the Red EB, when it was was Supercharged it had a custom spec cam in it. Not sure what they called the Cam though. You should be able to purchase that cam from the workshop though.

i have been told that turbo cams are different to supercharger style of cams, as supercharger works on engine crankshaft revolutions, where turbo works on exhaust gas, so you would think the cams would be different, i have heard of pple who have had a crow cam, they then have put on a supercharger, and gianed alot of power, on other hand, turbo they wouldnt make alot, without changing cam, can anyone shed light on this.

[loxxr6]

Luke are the turbo cams the same cost as the normal dev(x) ones ?

I think the turbo cams are a little bit more expensive than the N/A variety.

From what I understand the main difference between Supercharged and Turbocharged cams is the exhaust lobe. The design of the exhaust lobe is very important when it comes to the spool rate of your turbo. Both cams would also need very little overlap to help stop you blowing your pressurized air out the exhaust.

Hope that makes sense.

hurry up and get ur dynoed lol

interested to see how much power u make

[blwneb]

can anyone confirm that the reb eb had a dev 5 cam

It was different to a standard DEV 5 Freddy. I just can't remember what was stamped in the back of it when it was put together.

However, a decomp'd DEV 5 race engine with a supercharger would be awesome. Mmmmm, maybe something for you to put in your car Fred. I am sure you could find a couple of superchargers lying around.

I cant get my car tuned till i sort out the clutch, The Extream CLutch Brendon put in my car has problems with gripping and thats without the Nitrus so monday will be going down there to speak with Brendon

[The Monty]

Sorry to beat in on the thread, but is there any difference, price or performance, between the dev5 and 3 cams for a N/A Falcon?

[STOKEB]

all the Dev cams are same price but i think the turbo grinds and other custom cams would cost more.

[Brenden]

Now Im here, I do use the dev5 cam for supercharging, it works really well. However its not so good for turbo's.

Sorry I took so long to get back.

I hope the little power dyne can keep up.

[blwneb]

So brendan you suggest the dev 5 cam for my setup, at the moment it only has a standard xr6 cam, I have fitted the supercharger, have fitted bigger injectors, can only run up to 3500rpm, and max 5psi before it starts to ping, i have to connect trex fuel pump and see how it goes, but what i want is to set the car up on the dyno, how long would this take brendan and what would be a rough cost for a ford forums member, and what do you think about these powerdynes, they are easy to fit but dont make alot of power.

[stiddy]

with a dev5 head/cam set up, and for argument sake the compression gets bumped upto 10.5:1 would you need to have it decompressed for a blower kit on say 9-10psi???

i know you would have to change the cam and decomp it for a turbo.. but im not questioning the turbo for those who are quick to jump..

but i was told for a blower kit to pretty much find the biggest baddest cam you can get your hands on, meaning in my opinion the Dev5.. and was also told compression isnt really a limiting factor when going a blower compared to a turbo.

If you want someone that cares, and will go out of there way to help a customer go speak to Glenn at GnD Performance.

I'm Sorry Stiddy If I have obviously upset you. It may seem that some of us have to much time on our hands to sit down and type insults and come up with imaginative ways to put others down.

I definately do not have enough time to concern myself with your small talk as my time on the computer is only short.

BLOWNEB,

In my experience with the powedyne charger they become unreliable when you try to boost them to much. Boost would relate to your pulley size.

When making big power, ie 220+rwkw you might be running a 7 lb pulley but only getting 4 or 5 in the manifold. This is simply because the charger cant keep up. You could go up another boost level but when your charger cant keep up, it tends to blow the internal drive belt's all the time.

Hower much power you can produce with the 7 lb pulley is all you should safely try to make, you could try the 9 lb pulley but be warned that the charger may suffer damage.

If it does you have 2 choices, go down a boost level or get a bigger huffer.

And the dev 5 cam is MADDDD with the huffers.

You must get your fuel system upto scratch, get at least the 24 lb injectors and must get a descent retune by the sounds of things. That detonation is not going to do you any good at all.

yeah yeah mate, send it to me in an email :

#24 injectors are marginal (at stock fuel pressures) arround 150rwkw. Any form of forced induction and i'd be looking at 42lbers or 30's at an ABSOLUTE minium. 80% DC+ = bad mkay.

With regards to cams, Breandan has hit the nail on the head the Dev5 would be a good blower cam (big lift, 22x duration and wide LSA), perfect for your poofterdyne.

[Walkinshaw]

With a turbo you will be looking for a bit more overlap to get the exhaust housing to spool. From all accounts the Wade 1521a was initialy developed as a turbo grind, mabey give the guys at Wade a call.
