Hay guys

My converted 3.8 isn't stock anymore. Have recently got the 380 manifold fitted with Graham's revised cams fitted and tuned on 98ron fuel. These cams are amazing and have made a nice gain no low end torque lost and a nice hit of power in the top end range. Even the 380 manifold has made a nice little top end gain. I've made a custom air box witch is very unrestricted with no bends. Very happy with car and still wanting more. The cars now as fast as the new xr6 turbos manual 6.0l commodores. It's insanely quick and silly.

Cheers kurt

I would like proof.

I would like proof.

Proof off wat mate?

How much power do you think its putting down at the wheels? I would imagine it would be up around 160kw atw? Even with a weight advantage to the magna, XR6 turbos and 6.0 VE commodores still put down 210-220 kw atw...

My car has a 3.8l engine not 3.5. A standard 3.8 will put down 160kwatw. My car now with the cam 380 manifold and 98 ron tune will have around 190kwatw

I would like proof if the power at the wheels and possibly a strip time. If you say it is fast, cool beans. But at some point, you need to prove it. I have a 3.8 and would like proof of these mods. It could be easier to do stuff to the motor when it isnt in the car.

Can you prove these claims?

Well I got half the proof on Brett h car he's got the same cams as mine but mine are the revised versions off his. His car has 180kwatw he has standard 3.5 manifold and intake and has been tuned for 95ron. I have cai 380 manifold and 98 Ron over Brett atm. But I'll eventually dyno and take her to the track. Got a mate with xr6 turbo manual dead even to him.

I will await the dyno then.

Guys, back off please, if anyone else posted this you would be all "wow that is great"

BrettH has also got the Graham Bell cams as has another car I have down here.

Given that approx 147 has been achieved atw by Steve Knight in an AWD I can not see any reason for an APPROXIMATE figure in a FWD Manual ATW

That's cool as! I myself have these and the 3.8. Only got them yesterday so they're still being run in but already can feel the immense power difference. The torque gain is insane!

i believe this setup would be over 180kwatw, wish i had one!

show me a dyno graph and i might throw one of these in my car, if i can find someone who will do a decent swap on my ralliart engine

I know Mal, I know about Graham.

I just want to see some depth to the claim. Otherwise it gets the same treatment as Brock's Polarizer. I am happy to wait of course.

Well you have already got depth to the claim unless BrettH is also a liar, which I know he is not

Here is a quote from Graham himself in and around Brett's car with these cams (Hope brett does not mind me quoting these figures)


In a stock 3.8 manual wagon those cams made 240HP on same Mainline, this is about 179kw ATW with NA

Now Kurts car is pretty much the same set up as Brett's car, both motors came from here, both have pretty much the same cam set up as well, not sure if Brett is running an LSD but I know Kurt is.

That is all the proof I need. And btw in Graham's own AWD he has achieved at the wheels 173kw using HM headers, mild head work and running on E10!!

On a final note, please (and you know who you are) stop singling out members as this will not be tolerated. I have deleted a few posts and any more may result in more severe action!

If Kurt is happy with the car as it is, that is all that matters. Sounds like a real sleeper, engine wise.

(I was going to say "WTF is that all about" to Kiffy, but thank goodness that post is gone.)

I promise a dyno will get done eventually

No hurry. Enjoy the car, no need to prove anything to anyone. That's my motto anyway. lol

WOW. I didn't know Graham's car had that much power especially in an AWD on e10 fuel. How much power do u reckon that would be in an fwd car?

Nice work kurt, have you been to the drags yet??

Remember Kurt that Graham has the more aggressive cams with the special springs, head work etc etc thus why his figure in the AWD was closer to what you would expect in yours as well as what Brett has in his.

That motor of Grahams in your car should produce more, only factor that may make a difference is the auto as well, with the set in the car I have done here they are great BUT I think they would be much better in a Manual personally

At the end of the day there are certain people you go to for items, Graham is the person you speak to about cams, he has spent most of his life working in the field and to be quite blunt (unlike me I know) anyone who would argue the point with Graham is simply a fool. He has written books on this topic as well has proven in his own cars what he can do with these motors and their respective heads etc

Nice work kurt, have you been to the drags yet??

I'm gonna be going in the next month to see how it goes. :)

I assume this is partly aimed towards my opening post. I am certainly not picking on kurt, in fact the car sounds like a weapon.

I have been in a 3.8-equipped magna so i know how hard they boogie with the boot up them.

I thought the going rate for a 3.8 magna was around 150fwkw atw going by previous dyno runs here in NSW that i attended. If kurts has 190fwkw then damn im not surprised its running with recent v8's and turbo 6's.

Hats off to you kurt :)

No Dave, was not directed at you at all, was directed to a few who have had posts deleted

Mal you should set up a conversion kit that includes a 6g75, 6g75 manifold and these cams and some valve springs all ready to bolt on, would be epic.

What are these cams?

Aaah ok :)

As said by Kurt and mal I had a set of Graham's prototype cams fitted about 15 months ago.

--dyno graph of mine is available in my ride thread (Brett h family wagon), and was as mal said 240hp/179.1Kw @ wheels.

(I also put a sound clip in the ride thread, crap sound quality but gives you an idea of idle)

I had read posts on Graham's work years ago and he seemed to know his stuff, however information stopped being posted up. When I had the funds I researched around fairly extensively to decide where to get some cams from and after speaking to graham on several occassions he definitely has a wealth of knowledge on how to get a car performing.

I figured if no-one was willing to take a leap and put up the cash then they'd never be proven one way or the other.
Anyway with his knowledge I thought it was a pretty safe risk.

Since i had them fitted I started out pretty apprehensive in coming straight out and posting everywhere about it until I had full testing figures available, as I was sure there would be knockers out there.

Some figures and info are available in my ride thread, but since having them fitted I am very happy with them and have recommended Graham's cams to several people, including Kurt.

I am aware of Kurt's set-up and i even stated to kurt myself he would be around 190kw@wheels with grahams cams, if not over. The reasons being kurt has the 380 manifold and modded airbox (which are two things holding my power down a bit), and also the fact that graham has made some slight but effective changes to the original set of cams he fitted to my car.
I have also spoken to graham since kurt got the cams and he confirmed that kurts car would be pumping out more than mine.

In terms of quarter Mlle times and 0-100 times in my car i haven't been able to solve traction issues since fitting the cams (lack of cash), however next week i will finally have the money saved up to (hopefully if my plan works) fix my traction problems and complete these final testing figures.
I can't remember the exact figure maybe Kurt can, but one test I did out at my parents farm was a 100-130 km/h run in third gear and it was I think 3 or 3.1 seconds or something, and it was still pulling bloody hard at 130.

I have taken A couple of members for a short blast in 2nd gear with these cams fitted (both have 3.8 conversions) and both had positive comments about the difference made.

I'm sure Kurt will hit the track pretty soon and post his results, and also in the next month or so I plan to fit my modded factory air box, and possibly 380 manifold (as well as said traction issue), with these I will go to WSID when possible and possibly re-dyno.

All further results will be posted when available.

Hope this clears things up for any doubters.

I'm assuming this is in a manual kurt?

Once I've worn these cams in and Mal has given the all clear I'll get on a dyno and get figures of what the new revised cams produce in an auto.

Yes mate it's a manual. Wat auto box does your 3.8l have attached to it 4 or 5sp auto?

Does anyone have contact details for this Graham fellow??? I would like to know more.

What do you need to know, I prob have te details you need

The 5 speed auto, it's in my TJ VRX

Hi Brad, please be aware these cams need a custom tune to suit. Magna ecu can be flashed so is suitable, however 380 ecu is another story.
You would need to address how you will overcome this and the extra costs involved before considering the cams.

What do you need to know, I prob have te details you need

Are these still made?

Yes these cams are still being made.

Are these still made?

As Brett said, sure are. I just got them put in couple of weeks ago

Dregg, these aren't going to work well with a supercharger if you were still going to go down that path. Either one or the other.

Supercharger is long term. These cams can be put in when the engine goes in. Everything will change with boost.

You said you want a budget build, i dont see how spending $1400 on cams and springs and 600 on a dyno tune + labour for installing cams and springs, you're up for 2500 already, then you need to buy another set of cams, the supercharger, a full ecu system and get it all tuned again and an lsd and new tyres and wheels, that 2500 just adds to a stupidly big spend man.
