Hi guys I'm looking to buy a resonable Cam for my '90 8v pb, golf. I've got an induction kit, recently overhauled engine which was balanced, 4-1 ss manifold, full ss scorpion exhaust, I also did some mild porting and polishing on the head. I now fancy a little more power.
I've seen a few but was interested in the Piper Ultimate Road Cam:
Powerband : 2500-6800rpm ; Power increase : 15bhp
Inlet duration : 276 deg ; Exhaust duration : 276 deg
Anyone have any coments or suggestions? I'm not to worried if the idle is a little off.
Thanks
Steve

i had one of these and sold it within a week.i lost all low down torque.yes it flew above 4k, but was unbearable around town. i then got a newman 268 off phillip walker on the club gti site. revs lovely all the way to nearly 7k, and noticeable but minimal low down loss. another is the kent gs2h cam, although more expensive than the newman
-
with the correct settinn up of the cam you can get a a hell of a lot of power out of it..obviously you'll need an adjustable pulley and with a little bit of playin around with the cam timing you'll be laughin. i advance the timing a notch, took it for a spin, then advanced a again, took it for a spin and then jst tweeked it until it was purrfec!
home tuning and road testin in my opinion is a lot more realistic then gettin it rolling roaded
-
Can anyone suggest a decent fast road cam? The piper Ultimate cam has had a bad review, any others?
thanks

newman 268, what iv got
-
i have run a kent 266 which felt a bit to similar to the standard one (for the cost of it) i then bought a piper 285 which is really good!the idle does suffer though! in my opinion the best compromise would be the kent gs2h or the cheaper newman alternative.

i got newman 276 and its still usable around town
-
I've got the Kent gs2h. Really made a difference when it was setup properly. Really pleased I went for it.
-
Did you guys go for the full kent cam kit or just the cam? is it worth getting their pulley for it?
thanks for the input guys
-
newman using standard timing marks so u dont need a vernier although i did for real fine tunning
-
I just bought the cam. Didn't get the kit; didn't even get the pulley.
-
newman are real good quality/price.as said, you use standard timing marks
-
Well after some thought aswell the input from here, I decided to spend a little extra but not as much as some others out there. The Kent GS2H, with pulley.
Ordered on sunday night, the cam was already here when I got home wed afternoon. The pulley unfortunately was not ordered from kent by the dealer who I ordered through! so the pulley and therefore the install is going to be delayed by a week :sick: I'll post an update when I can, quite looking forward to it! :grin:
-
The tuning/timing is the important part; get that right and it'll make a noticeable difference.
Nice choice. :cool:
How much did the pulley set you back?
-
I paid the costly sum of £116.33 inc VAT :angry: but if thats what it takes to dial it in properly then i'd be wasting my time and money not buying it :laugh:

Can you fit an adjustable vernier to a stock cam that comes with the PB engine?
Is it possible to get more power that way?

The digi engine can adjust the timing to stop knock, it has been said to leave the timing as is since the ecu needs to know. If you have a different cam then you need the fine adjustment to compensate for any variances including having the head skimed. I'm not 100% though, anyone else know?
-
all you guys with new cams in your cars must mean there are some standard ones kicking about?!looking for one for my driver sooo if anyone wants to sell one-let me know.
also, i'm not sure if you'll know am i best off fitting the distributor off the gti as well as the cam to aid the advance?
cheers for any help

An update guys
Had my kent GS2H cam and pulley fitted, the info on it said +14hp but I think +10hp is probably a more realistic expectation. I was never going to go wow thats sooo fast! but is it pulling well and virtually no adverse effects at idle. I am still going to make small adjustments to the pulley by advancing 1 degree at a time and checking for improvement. I let my mechanic take her out for a 'road test' and he was impressed by the top end acceleration. I am hoping there is rolling road session coming up in the next few months to get a reading!

Thats good to hear :cool:
I don't know my geography but there's a forum RR day at Awesome in Manchester in April.
That'd be a good chance to get some readings :smiley:
