Hello Folks,
I'm considering ways to get more vroom-vroom from my Griff 500, looking in particular at ACT plenum and a Tornado chip (with Mark Adams RR session).
V8 Developments have suggested a new cam - P404 - has anyone tried it? Apparently, with the new cam, improved induction and a properly mapped ECU, I could expect a power hike of around 60BHP...
The story goes on to say that drivability will be much improved too, so it all sounds just dandy. However, I'd really like to hear from anyone who has experience of this (or similar) project.
Best regards,
Marlon.

had a 404 in mine, for about 5ooo miles now.
taps like a bugger after 1ooo or 1 trackday.
loads of torque, mine runs with an RT filer (KN) ignition at 31.5 degrees at 4000 revs.
Mark adams had a look at mine, and told me not to bother chipping! infact he thought he'd already chipped it! we checked...he hadn't
only 275 bhp (500HC) but around 300 lb/ft from 2.5 - 5k revs. ( and that was with the tappets all over the place!!!!!
Idles fine, picks-ups great in any gear and has no lurch above 1,500 revs.
if you can live with the noise, get one!

01775 75000, say I said to give em a call
Hmmm.
I'm a little concerned about the lumpy idle and tappet noises. I don't expect a 5L V8 to be as smooth as angel delight, but I would like to keep it smoother than (to use the title of another recent post) Granny's custard! Not that her custard makes tappety-tap-tap noises, but some of her joints do so there's an analogy there somewhere. Perhaps. Not.
Maybe I should get the ACT parts fitted and get the cam done later when I've experienced it first-hand on SOMEONE ELSES car! Is there a good reason why I should wait until the cam decision is made before I get the car re-chipped and RR'd? Presumably the new cam would change the engine dynamics and require different ECU settings? I'm guessing, so please correct me if I'm wrong!
Thanks All,
Marlon.
