I am fairly unhappy with how my car pulls right now with the 62mm pulley, 30#ers, ES IC piping, 5-5 and rallye outlet. I have not really seen good information about the power gaines from the stage 4 gladders verus the stock unported gladders. My supercharger has been rebuilt recently so I was going to just wait till I needed a rebuild. However since I am so disgruntled about the way the car pulls now, I need to do something. I was figuring that the cam with new lifters, gasket, and a cam gear will come pretty close to the price of the stage 4. And it looks to me like the 260/268 is a pretty mild cam.

Re: Stage 4 or Cam (V8SHME8)

before the stage 4/rebuild, i used to want to floor the throttle all the time. now after the rebuild, it feels like there is power to spare, i haven't put the throttle all the way down yet i don't think.. if that helps at all. major difference in the feel of the car. you could also adjust the boost valve linkage on the throttle body to close sooner, giving better throttle response.. heard good things about that.

Re: Stage 4 or Cam (itchyG60)

the head is mild, the cam is a band-aid.
fix the root of the problem and you'll see the power that you seek.
(sounds like some matrix bull **** huh)

Re: Stage 4 or Cam (V8SHME8)

Get your head flowed, and rechip the engine.
Take care of a good exhaust and 230hp must be in it.
By the way 62
Take a 71 of 68 this wil do. (I have 229hp with 71)

ya.. but not as much boost as low in the revs as with a 62mm. just can't go over 6200rpm with a 62mm.. but with stock head, why would you want to?

my crappy ass motor pushed 150wft/lbs @2000rpm with the 62 (nothing rebuilt with a 268/260 cam even.
i love low end torque. [email protected], [email protected] yeah baby!
as you fiddle to downshift, i press the gas and go


Use a 71mm and doing 143.8 ft/lb but can rev to 7300rpm without killing the charger.
Tourqe gets 206.5 ft/lb at 4600 then drops at 5400rpm with still 118.2 ft/lb.
(results after dyno)
So why a small 62? No need of low end tourqe, only results in wheelspin in 1/2/3 gear.
But a wide power band is much more useable.

Spec of the engine
-Groupe A charger (special stealseals and strips, compl. flowed)
-71 wheel
-Large IC of the golf G60 (flowed)
-4-2-1 exhaust 60mm supersprint
-K&N in G60box, no silencer (cost about 9hp in top!!)
-JDengineering cam with swingboost effect 272.
-grey injectors 345cc/3.5bar
-JDengineering chip (no knocksensor, no idle stable steering, no cold start adjust)
NO headwork no valve jobs.

Re: Stage 4 or Cam (GTI1-G60)

Now running a smaller pulley, I can see why he wants the 62mm instead of the 71.
There's a big difference in driveablility running the small pulley. The low and mid range torque you get makes the car more difficult to launch; however, in 3/4/5, it's much more pleasant to drive. You can cruise at lower RPM's and still not need to downshift in order to accelerate. It feels like a different car.
My peak boost didn't go up much moving from the 15 to the 20psi pulley, however the difference in TQ from 2000-4500 is insane. Much more fun to drive.

why rev past 6000rpm if you haven't had any headwork done? that's just wreckless/pointless.
don't you think there is a power/response improvment by dropping the pulley size 7mm from 78mm to the ladies choice 71mm pulley? so the same thing goes for dropping it another 9mm to 62mm.. much more boost much sooner.. and if you're not into creating undue stress on the motor, heat, etc. by reving the 8v past 6200rpm (past where the stock PG head stops flowing) then the 62mm pulley stays within the g-lader's design limits.
if you've had headwork, 16v conversion, etc etc are taking it to 7000+rpm for a reason, then thats another story.

"past where the stock PG head stops flowing"
Sorry, but after 4500rpm with a 272 cam flow drops like a waterfall....


"why rev past 6000rpm if you haven't had any headwork done? that's just wreckless/pointless."
No, tourqe climbs till 6000rpm after that you need the extra 1300rpm to cath the rev fall when shifting at 1/2 gear.

"ladies choice 71mm pulley?"
No it's calculated....
And the hole engine matches.
Giving that powerband you want for street use.
But mayby I forget that whe have a 120km limit on the highway's.....

Re: Stage 4 or Cam (GTI1-G60)

every setup is different, if it works for you then giver! http://****************.com/smile/emthup.gif
for many people, sticking a 62mm or 65mm pulley on there makes the car a lot more responsive and is a welcomed modification. anyone i've spoken to with a 62mm pulley loves it. my car has a brand new ported charger and an original unrebuilt 8v with 205,000km on it. i personally would rather spin the charger a little faster then take the engine over 6k repeatedly.. not to mention that i'm after low-end grunt, not so much performance after 6000rpm.. its not a rice rocket afterall and the head isn't ported (yet).
i'm all about the low-end pull.. i speculate from everything i've heard/read that the 62mm will just make it that much more fun to drive.

Re: Stage 4 or Cam (mrkrad)

Mkrad " 150wft/lbs @2000rpm with the 62 "
GTI1-g60 "143ft/lb @2000rpm with the 71"
7 ft/lb less.....and no risc of a 2000$ charger blowing to scrap

Still want a 62?
Ok, but first start with your engine...
.
But ok, in Holland whe no **** about the G60..... whe hardly see those cars anymore....

Re: Stage 4 or Cam (V8SHME8)

Porting the charger is really not worth it unless you can do it yourself
cam is a must, 268/260 is the absolute lowest you should go, 268/268 is the way to go if your a lil unsure, i have a 276/272 high lift cam
the stock head will not breath past 5500ish rpm so if you want power porting the head is where its at, my car pulls WAAAAYYY into the 6000's wtih that cam and the ported head and im only running 10 psi off a 68mm pully

I did the porting myself.
Don't be mistaken the 10psi is IN the mainfold and NOT the flow of the head!
So what you see on your boost meter is only for a check and NOT a figure for power!!!

No, tourqe climbs till 6000rpm...

Then how do you explain torque PEAKING before 5000rpm? That means it no longer climbs after that point.

Re: Stage 4 or Cam (Iceman666)

I am not going to change to a different pulley which means I am going to no be reving into past 6 grand. If what you say is the case and porting is not really as beneficial as the cam then I will get the cam. It seems like I got more advice about what pulley to use when that was not even the question. If I go with the 276/272 cam, will I have problems adding nitrous later down the road. Also, where can I get these other cams you are talking about. All I can find are the 268/260s.

...you don't understand. When torque "PEAKS," that means it has reached the maximum output of torque. From there on, torque does NOT climb. It DROPS. Hence the term, "peak," or "the highest point."
