FG F6 Sedan build to 600rwhp

[k31th]

simple fact... you can go over 1000hp on this motor without needing cams or seeing a benefit from them. If you want the cams for the noise and a small detriment in either low end or top end performance, then go ahead they do make the engine sound different (whether it's better or not is fairly subjective)

 

who's spec'ing the turbo?

It won't spool the same as the stock turbo

The thing you have to remember when modifying the profile of cams is that while it may give you more peak power, you can actually loose power under the curve.

The fg cam is near perfect for the motor and has run 8 second quarter mile

Change the cam all you want just make sure you change everything else to suit the new cam profile

I am by no means as car smart as Some of you guys but so far every article I read says that more lift and duration on boosted engines is a good thing. If the tuner is good enough there should be power gains across the entire rev range. NA ENGINES are different and there can be substantial power losses. With the GTR I increased both lift and duration slightly and it felt like I stroked the motor. Everything improved. Ressponse, lag, power. No losses anywhere.

You just summarised 4 hours of reading for me. Where were you last night

[k31th]

while he might be right, it still has little or no benefit on these cars.

VCT FTW!

In a turbo car you want over lap and bigger duration/lift as it helps push the exhaust gas out the motor faster therefore increasing power output

Mightbuyafords statement isn't 100% correct for a turbo car with dual vct and even less so in fg on with duo phased cams.

 

Have a read of the specs page for atomics cams you'll see the pattern. Lift and duration are the key factors. Overlap is variable bf on wards.

How many people disable vct in cars with over 700hp? 90% of them

In B-Series and F-Series falcons, it's extremely rare. Most people who put in fixed cam gears end up going back to VCT

I am going with atomic for allot of the parts. Oil gears, valve springs. The cams are still a couple of months away. If all turns out well and I have the funds, I'll do the cams last. That way we can see a direct comparison before and after.

First and most it is a daily driver so response is important. Accessional hill climb and drag strip trip is second. 

 

Looked into e85 storage and unfortunately it's deffinetly out of the question while I have a toddler. I spend allot of time in and around the garage in my trade and he is with me all the time. One bad step, one moment of lapse in concentration and I'll be on the news as the worst parent. 

 

Has anyone here rolled the guards on an fg? Just want to know the width of rubber people are able to squeeze under their sedans.
