I'm running an FP3 type cam and have been advised that it should be good for 750 or so HP.
I really think that the cam is either not dailed in correctly to suit the turbo as I haven't touched it (zero/zero).
With the GT35 it was a very broad power range.
With the new T51R SPL, it comes on very late and peaks at about the same HP as the GT35R at the same RPM.
Power quickly drops off after 6500 rpm which was similar to the GT35R.
I'm thinking, maybe the cams are currently running well and set to run well mid range but the T51R SPL is not really complimenting the cam settings so it makes crap power up and and doesn't spool enough mid range to make much power either.
I will have to retard the exhaust cam and see if it helps.
I plan to rev this 2.4L long rod motor to 9k.
Hopefully she holds together!
If the cam adjustment doesn't help, I'll be looking at either Kelfords or GSC S3 cams.
Any advise on adjusting the cams and what type of changes I should see?
I've got crappy notes here when I built the motor:
Doesn't make sense to me now that I look at it.
My notes state:
CAM ADJUSTMENT
Exhaust: 5 degree RETARD MAX / 10 degrees ADVANCE
Intake: O R ???? / ALL ???
I should have taken better notes.
It was just scribble in my notepad of what the MAX adjustments were with the HKS cam gears using a soft spring and feeling them touch the piston.
Also 5 degree RETARD isn't much at all.
Did I mean 5 marks of the CAM Gears? which actually = 10 degrees?
Very annoyed.
Anyway, I might have to dail in the cams on the engine and set the cams for max top end.
Opinions?
Advice?
