Stage 3 cam

[Jesusdroveawestfield]

Barney, interesting that you are getting 158hp. I guess your internals are still standard ? Also you say you have a poor flowing intercooler. Is this a JD one same as mine ?

[Barney]

yeh, the internalls are standard, even the head.
so i surpose 156hp @ 4200rpm is ok for a standard engine.

I will see what happens with the new cooler

In respect to cam stages, I imagine this is a way of identifying with cam profile was developed first during production of a race motor.

Stage 1 cam was possibly the first profile to be tired and used, then the tuner guys adjusted the profiles and ground a new cam, thus calling it stage 2, and so on
Apparently there was 8 stages of devolment in these early days with the later cams being used in far more advanced motors.

I think the "stage3" profile was recomended as it may be a good all rounder suited to a street driven car.
In race/rally circles cams are often quoted as a "no. ? " cam as aposed to "stage ?" cam.




Daz, what was done to your head? just enlarged ports, or did it recieve oversize valves/springs as well? Oh, and what size is your turbo?

[Cam]

Well i only know of 4 Cam stages
1: Happy
2: Angry
3: Frustrated
4: Depressed

Currently im in stage 4

Ron matched the inlet and exhaust ports I believe and of course enlarged them in the process. Other than that it is standard. Turbo is a TD06.

[Cookiemonster]

I thought you had bigger valves in there as well, Daz.

[StarionChef]

ya tdo6 what Daz? 16g?

[NXTIME]

The TD06 will have an ID tag on it with part and serial numbers as well as compressor wheel size stamped on it. It will read "TD06-17C" or similar. What are the 3 characters after it says "TD06" on this plate Daz?

[Barney]

Those people having problems with power dropping off around 4-5000 rpm do you have standard valve springs :?:

could the standard springs be to weak when the engine is reving hard under full load, especially when running over 12psi boost. :?:

I have double valve springs.

8 stages of what? or on what to be specific.

Nah thats an old Lancer thing "factory number 5 cam" cos it has the number 5 stamped on the back of it. It's abit like Datsuns with their "Option" bits. The number 5 thing was just for I.D.

:D Hi guys my 2 bobs worth my starion starts slowing down at about
5000 revs 5500 to6000 bloody slow, so power droping off after5000revs
my car is standard. another starion i drove a couple of months back was
standard except for a small intercooler and blancesharfts removed and
i had trouble change gears befour 6000revs so it was making good power to at least 6000revs

Barney,
what ignition timing do you run in the Wolf system at full boost (and what boost) at each speed (say each 500PM)? Also with your modified L300 manifold are the runner lengths the same as standard?

thanks,
Mark.

[decoy]

did you have the same turbos pcuser51? although i noticed i got a bit more top end after i intercooled.

[TD05]

I've been reading on another starion forum that maybe this problem is related to cam timing, apparently even when the stock cam is aligned to all the factory timing marks the cam can still be out some, this is considering manufacturing tolerance could out by a hair or two in all or some components, it all adds up..
