Just want to know what is on a memcal that gives a motor the potential of 215Kw (random figure) out of curiosity, if the standard 5ltr with a potential out put of 165Kw had the memcal swapped for the 215Kw memcal would the moter be capable of anything close to this power. Im trying to get my head around the difference between all the cars that commodore put the 304 into. and they all have different power out puts. also wondering what would need changing If I put in a 308 boredout 060 thou and strocked.

| no idea to tell the truth on the memcal, but I do know this , anything is possible with the memcal its more if you car responds right to it! as for putting a 308 in a vn mainly g/b to suit the motor and I'd assume the the tail shaft would be shorter and also the wiring harness would need to be redone! |

The VN SS Group A was the only VN to have a 215kw power plant and it had a lot more done to it than just a memcal ;) The HSV cars of the day often had changes to the cam, exhaust, air intake, fuel injectors and chip among other things. Especially the 200 and 215kw cars.
I have a list of what engine modifications were carried out to each VN and what the power output was at my site.
You could get a chip that would claim a power increase but they are hit and miss. I would be extremely weary of anyone offering a chip that'd give you 215kw. That's a massive power jump in the context of things and you are usually talking cams or more substantial mods to pick up that sort of power.
And what needs changing for a stroker? Are you talking about what is needed to stroke it or what else would be needed to keep it happy (fuel systems etc)? That's assuming by 308 you mean the injected 304. To fit an older carby 308 you will be having all kinds of nightmares getting it engineered and registered- they don't really like you putting older motors in newer cars. |

I was toying with the idea of running the 308 block and bolting the top half of the 304 on it. Im only imagining the 304 and the 308 block use the same external dimentions. This is an uneducated idea as I have no ide if the oil galleries, the water ports or even the bolt pattern would match up not. The only reason I ask about the 308 block bored 060 thou is that I have one in my parents shed that I am trying to figure out what to do with i.e. sell it. my concern is that when it was bored it wasnt done on the same plane as the original bore. and yeah wondering what would need to keep it happy. Sorry I realise the crank and rods need to be changed and allowances need to be made on the block to accomodate the larger crank. |

No idea on the 308 front as I've never had much to do with them.
As for what else would need upgrading, depending on the cam and power you're trying to get it might need an upgraded fuel system. You should be right for spark and the factory computer should handle it. I know one of our guys just built a 355 for a VG ute that spins to 9000rpm so I'll see what he knows about it. |

Thats what I thought about the memcal. I thought cam timing would have a bit to do with it. For the what its worth the match port and polish is a definate. I really have to admit I do find the idea of some old geazer hacking away with a die grinder and slipping the bur down the valve stem port. I was only considering the bowel job on the intake side primarily for improved flow. I am interested to hear about the 355 VG

pm me if you want a memcal that will give you 190-200kw at the motor with high flow air filter and exhaust, depending on the condition of your motor/electrics.
Theres alot of initial potential on the v8, when they come out of the factory they had a weak tune and restrictive exhaust/air intake. If you get the chip you will always have to run 95-98 ron fuel otherwise youll have a case of the knocks.. |

ROFL LOL oh god now my face hurts. thank you mild, I wasnt really paying attention when I was typing got a bit carried away in the moment I hope you cleared any confussion up on that dont really want ppl guessing what to do with that and shove the garden hose up the exhaust and turn the tap on.........I take no responsibility for any one damaging there car in this manner as I was refering to heads at the time. Hae been looking at stage 2 cam packages. Cam, memcal valve springs......not to sure what brand to go. |

The chip you'd get in that package isn't worth anything mate. You'd need a tune to get the most from it.
The packages aren't too bad but you might be able to get the parts seperately from cheaper elsewhere. And don't get conned by stages- they all mean different things to different companies. Talk to them about KW gains, lift and duration. |

| basicaly to get the most out of any chip , and here is were I see most people going wrong! every chip that has a tune is fine but that dont mean your car is right for it, it might run 10 fold to what your used to but to get the most out of your chip it realy needsa dyno tune! alot of people think its gonna give you all the power in the world ( wake up call ) it wont , like I sed you might notice a difference but all or most chips are desighned with max performance /or cruising in mind and thats what the dyno defines. most cars with a good tuned chip will notice a good difference but that dont meen its right either, it can run rich as fuc wich most after market chips do , but again they have performance in mind! Allways research the chip you want for your car as it can either be waste of money or cost you more money in the long run! |

| lmao nodg have you hit the silly pills or what ? greenfoam seem s to be the ducks nuts but you alone ( being a mech and all should know) that a dyno tune regardless of the chip u have, will bring the potential out in your motor or am I wrong ? lmfao! and 1-2 kw of what nodg bull sh1t? a dyno with the right chip will give sh1t loads more than u quote u know this? so y say such rubbish you put your stats up ... oh hang on it was a 0-100 in 7 secs yeah? and that was b4 the chip so what is the power gain you have added and I know yours hasnt been dynod! So ?? hmm so many questions! |

| you wouldnt get more than a kilowatt or 2 if you had to improve the tune i have at the moment on a dyno and it would cost me hundreds. this chip im selling is similar to an off the shelf powerchip gold which sells for 600 bucks, im selling one thats been further tuned for 45 dollars. i dont care if he buys it or not i just hope he listens to the people that have done it before and know what there talking about, why get an expensive dyno tune when your not going to feel a noticeble gain. |

Greenfoams chips differ to the off the shelf jobs because he takes your individual set up into account.
As far as cheap options go, everyone with one raves about them (Greenfoams chips). I know a few people using them and all say very good things about it. Does it replace a dyno tune? It depends on the $$$ you want to spend. |

its complicatated, by chatting to him for the past few months ive learnt alot, the stock vn v8 tune is a little weaker than the sv89 tune (180kw), the chips he tuned for me is what he burns for everyone else that has my same specs (airfilter, 2.25-2.5 exhaust) his spark advance tables compared to the sv89 tune is phemonimal, i will get the exact details off him tonight to show how much of a differance there is, in some spots of the rpm range, the same spark sdvance is used which is called lean cruise, in greenfoams chips instead of staying the same advance throughout the rpm range the spark advances higher.
The differance between hetween the stock tune and his is that great that any further tuning would only yield minimal power, he has the same car as all of us and has been playing around with it for 3 years, if the electrical system is pumping like it should and if the base timing is set to 10 degrees it will not ping, damage anything and will give better economy, i reset my trip metre and half highway half city driving im getting 12.5-13.5 which is as low as it used to get as the staesman on the highway at times.
A dyno tune would be better but for 45 bucks, the majority of the gain is already there.. theres a member on justcommodores and qld commodores called pumba, he has a microtec ecu and tune which cost him an arm and a leg (on a stock motor) and is getting the same 0-100 and 1/4 times on the gtech as us. I know its hard to belive how something so cheap and over the net will just instantly boost your cars power i didnt belive it until i bought one, i should get him to come here and answer any questions you gusy have, he really does know his stuff when it comes to tuning v6's and v8's. |

| Forgot to mention, the tunes he does for the internally stock 5 litre have the same spark advance on each tune, the only thing that can differ is if you have a 2.5/3 inch exhaust, a little extra fuel may be added, other than that evry tune is pretty much the same. |
