so, last night we began to strip the car ready for the new camshafts:
and they arrived this morning! this is the full Regal Autosport Cam Pack:
comes with, inlet and exhaust cam, fitting kit and vernier pulley - notice that two hardened and coated fuel pump lobes are included...
one is slightly higher lift than stock for road use and gives a higher rail pressure than a standard cam would, and an even higher lift lobe for motorsport use - so i should be able to retain full FSI when i go for really really big power later :D
the pump lobes themselves are specificially hardened and coated to work perfectly with the OEM update coated pump lobe follower (bucket) and reduce bucket wear over the stock setup. ALOT of effort has gone into this and currently we are the only cam supplier able to offer this improvement... you dont just get more power, but more protection too!!
stock cams out:
last week i had the car on the dyno and checked the health of the car and did some runs to give a baseline for improvement with the cams and i noticed a slight drop in power to 363bhp and an intermittant drop in sustained boost levels... i eventually tracked it down to be a fluctuation in delivered rail pressure, which was causing the car to pull back timing which in turn affected the boost...
and today we found the cause of the rail presure fluctuation i had been experiencing on the dyno....
the dreaded lobe wear!
now you all know why and what happens when this starts haha
as you know this is extremely common on all 2.0TFSi engines but the good news is the new cam pack we have put together includes a hardened fuel lobe and is specially coated to work perfectly with the updated OEM buckets, so this wear will be significantly reduced and i dont have to worry about checking for wear periodicially
will be a nice peace of mind!
im genuinely excited about this cam pack, because it is a genuinely better design than stock - and not only gives more power but addresses a common 2.0TFSi niggle, and that to me is absolutely what modifying is all about!
also going the mundane cambelt and water pump at the same time, and will aim to get the RS4 fuel return valve in too - with any luck i might have an idea of the power gains by tonight!
fingers x'd for me :D
