Ok Boys long post time. but heres my opinion......
I picked the car up at 11am, and have only just parked it up, to say that im happy is an understatement, i was worried that id made a mistake the last thing i wanted was a pig to drive, i had a SLR Torana as a kid with a big cam, good when your 19 but you soon tire of that. Im in my forties now, plus the with the w375 the road manners were good, but i wanted more power. Heres the thing coming from an xr6 turbo that was putting out 350kw i wanted more power, and the last thing i wanted was to get smoked by a bog stock xr6 turbo with my w375 kit on.
So i wanted more power but as im trying to pay my house of as quick as i could i didnt wanna put boost into it and spend 18k on it. Decided Cam time did my homework on the w407 and said just do it. What i love about Walkinshaw stuff is they have done the R N D and theres no way theyd put a stupid cam in it, especially if it needs warranty, so i trusted them
Ok hows it drive.... a hell of alot better then i thought, firstly its got a really nice idle, you really know its cammed, but driving it you wouldnt if that makes sense. Mine drives better then the test car i drove, Brett from FTP said how do i like the power, as in where do i want it and i said a bit more down low. So it was tuned, cam comes on at 2.800rpm right through to sign of time. There was no where any surge, coming back from the gym i noticed. In a 90 zone i could cruise in 6th gear, with this w407 i can too, but its close to the edge, also its got a **** load more bottom end power, you dont realise how gutless down low the w375 is, until you plant it in the w407 down low. All the power in the w375 is up top, as with the w407, its all midrange exactly where you want it on the street. I tell you what we pay alot for Walky gear, but it is top quality and they do thousands of hours in R N D and we beneffit from it guys..... best thing ive ever done. quickly too, as i got there an hour early just in time for its tuning, i was not only invited to watch the car get its power run, but Brett said jump in the car with me. Im kicking myself i didnt record it.
Anyway car made 392 with the w375 pack brand new. with the w407 it made 446 HP at the wheels qiut happy. remember this is a baby cam, Brett its the second highest he has seen for the w407 in manual, most of the them are hitting 420 to 435HP
Anyone thinking of getting the w407 kit do it, to the point its a Way better upgrade then the w375 kit
Kingy out
