Consider your options guys as JMM is only a drop in the ocean of camshaft manufacturers. The other thing which has always bothered me is that you can never get any info out of mock, he just snobs you. If you go to any other well know dealer they tell you all you need to know, specs included, who wants a regrind JMM devo5 anyway. I'd much rather spend the money on turbocharging to receive massive effortless torque and still retain close to factory fuel economy with the origional cam and final drive ratio.

because he is asking about THE DEV 5 cam not other cams

and with the drop in the ocean bit mate lol is all i can say to that

keeping on thread all i can advise is if u want the best cam go with the one thats in the fastest street legal 4.0n/a 13.3secs (dev5) and u cant go wrong :Up_to_som

[stockstandard]

[5speedeb]

thats not entirely correct. If you are jsut talking NA I6 then Injected250's 12.612@107.12 in a 4.1 Cortina pretty much destroys that theory. He's not the quickest I6 Cortina either I dont think.

[stockstandard]

deleted - not sure what happened there :nutsycuck

[1TUFFUTE]

this thread is about dev cams in 4.0 motors so it means nothing(cortina..what the : )

[5speedeb]

im refering to quickest e series a series 4litre part of things not the cortina 4.1 part of things and if i was then ur right

2 different things

[5speedeb]

quickest 4 litre n/a falcon i shouldve added in my last past

is that enough feedback bud. Have u decided what ur doing eventualy?keep us uptodate...

[slamd ef wagon]

i made 134rwkw with a crow stage 2 im getting the stage3 now wich needs a chip,hd springs chip is suposed to give me 7-10rwkw alown(chiptorque) so i hope to get about 150rwkw

i didnt notice that much differance with the stage 2 but the dyno showed it did id recomend crow they have good service(after sale) i rang jim mock and i thort he was quit rood so i took my bussiness to crow and saved heaps

my cam was $340 for a brand new billet
mocks are about 400+ for a regring

maybe ur right bud but it could be the simple fact that the cam is designed to optimally perform with the whole kit as a complete package after years off reasearch on the 4.0. Thats why u can go buy hugo boss or go to lowes 4 ur clothes but its up to u. Maybe u should be trying to prove that the cam itself is crap like the thread is asking...

[MADED-6]

well it seems alot of ppl dont like jim mock but they have no bad things to say about his stuff i want the cam not the bloke himself. i mean freddy and dev5 ute are right if u have something bad to say about the cam say it dont tell me that jim mock himself is an a@#hole. i want a cam that with headwork will get me into the 14s and maybe even without and i want a cam that for the time being wont need a chip to make it idle and the dev5 will do these things. so please if u have something bad to say about the cam say it and if u have a better cam to advise me to get then say it and i will consider that. thanx everyone for there help.
cheers josh.

Dude, that car did 12 seconds on NITROUS... N2O is not N/A
it did like mid 13's N/A and that isnt too impressive seeing as the car is nowhere near streel legal.. has a fully rebuilt race spec engine, and took the front sway bar out and was on mickey thompson tyres. meh, a backyard hack could do that.

not that impressive hmmmmmmmmmmmm 13.3 not at all thats a crap time
every tom dick and harry can do that gees i wonder


and where was the nos bit mention in the above post that u quoted i dont see anything

[EFFalcon]

what ever the case is, the JMM car is the fastest 4.0 N/a falcon, it did a low 13 second pass, and is the quickest.
weather its fully street legal doesn't really matter, its still the fastest.
then it did the 12's on n2o, whihc as said, is no longer n/a.

no one can dispute the JMM car being the fasests 4.0 I6 Falcon.

I have dealt with the mock team in the past and whenever I spoke to them (jim on the phone and brendan via email) they were always helpful and polite. They may be a little like all of us and have the odd bad day, but it's no reason to give them some of the grief they have been copping.

As for the Dev 5, I have heard that wihout the headwork at the same time, the idle will be very lumpy and probably not suitable for an auto, but a manual shouldn't have too many issues. With the headwork you plan, I don't see 14's being too much of a problem. Look at a chip later to help optimise your settings.
The Dev3HL cam I got has worked wonders and my top end is far better than before. I have a fuel issue down low and a re-tune will hopefully sort that. I went the 3 because it was recommended for an auto with no head work.

Good Luck with the hunt


MY TWO CENTS
Too many people are flaming different businesses and changing camps too easily. I am interested in working on the car. I'll choose parts and workshops that I feel meet my requirements, not a name.
To the camp jumpers, get over it and stop throwing your insignificant point into the ring instead of helping people.

[1TUFFUTE]

bout time this thread got on topic with some real responses :

oh and MACK 6..ur 2cents worth is worth more than u think bud :

[1FLYRYD]

i had an auto el and i put a dev 5 cam in, i had a lot of problems wif idle and timming so i chamger it for a cam that was bout the the same specs as a dev3 althou now i think of it the timing probs could of been avoided but some people i was workin wif didn't have a clue, i say go for it

[MADED-6]

yeah i really want to get this cam and most likely will but ive gotta save up so i can do a fair bit at the same time. being an apprentice isnt the best payed job lol. anyway thanx everyone for there help. and evlelf wat do u mean 13 seconds isnt that quick u needed to put 7-10psi of boost into urs to run the same times so i recon thats a f#$kin good effort. anyway cheers josh.

[evlelf]

yeah but that is a 4.0 litre performance specialist shop's demo car.. with a full race engine rebuild, it is quick, no doubt about that, but it would definatly be expected with the money involved, if you read up about it they say that for what they've done to that car.. $15,000 should cover it. Engine wise on mine i've spent half that. That is why im saying its not that impressive.. If you gave me 15k to spend on an engine, i could make it go a helluva lot quicker than 13's mate

My car is as quick as the jmm car mate, as i said, with half the money spent that they did. And im quite proud to say its mostly backyard work.

[FPVWEPN]

but thats not the point!!!!!!! it makes the same power without 7-10 psi going into it!!! and to get a n/a 4.0ltr into the 13's is probrably the equivalent of getting a forced 4.0ltr well into the 11's RELIABLY

So how quick? and your's isn't N/A so you can't compare your car to jim mocks car? It is harder to get a full street trim falcon to go quicker than 14 flat N/A than it is turbo'd or supercharged. You have missed the point of this thread completely :

[OED666]

i think JMM know their stuff, but a bit over priced...

i had a regrind cam in my ED motor, and i managed 203.2RWHP, and trap speeds that indicate a 14.5. Launching was the hardest part with my car.

I now have an AU XR6 motor with a big cam, and its only putting out 217.2RWHP... Low 14's is what i am aiming for now.

If lifter shims werent so hard to get, i would suggest getting a regrind cam, similar to what i had in my ED motor. It went hard, all the way to 5500rpm..

My ED motor was stock as a rock, and had 260,000k's on it. Its still alive in another car now, and going hard!!!

[94EDxr6]

this is 94edghia but im on my mates computer. im not saying that ur car isnt quick evlelf im just saying that 13's is very good and i do think that u could make a motor a helluva lot quicker than 13's with $15,000. but there cams are very good i think but i am rethinking this mod now because i didnt no they were a regrind cam so i might get a chip and run a big wade cam as that would be cheaper and the 1521 is a billet cam not a regrind therefor u dont need to shim it. anyway thatnks everyone for there advice. cheers josh.

[heckaz performance]

Regrinds are a bit lame, especially for those bucks, many cams would do the job, dont forget that the mock car has head mods. ed head is supposed to have bigger ports than later on and flow 380hp. Many cam manufacturers have a cam that will get you into the 13's, especially with all the no expense spared, engine, driveline and suspension of the Mock-vehicle. It does not suit street use and apparently has driveline vibrations at 80k's due to a pinion angle modification. If anyone wanted to waste their vehicle drivability I'm sure they could challenge them.
Durations around 230@0.50" would give em a run.

[STOKEB]

Getting a 4.0 to run a flat 14 or a high 13 isnt that hard to do and you dont need to spend big $$$$$$ on it, Look at my old motor all that was done to it was a eb block, with eb crank, AU rods and ACL AU pistons, with comp at 10.1 and a au head that had hardly no porting done to it, just bigger valves and springs with the dev5 cam init, that ran a 13.9@104MPH NA no NOS. That engine didnt cost me an arm and a leg cost me about $2000. Who cares what everyone else thinks about JMM your purcashing the product not him, if the product works then why care what everyon else thinks, its your choice mate go for what you want....
