Yea your pretty useful Bellend!!

Yea I'd love too, but in all honesty the coins are running low, and I still need to build the box!

Haha I warn people not to take anything like this on unless you have a spare 15-20k growing on a tree out the back or something, I wish I listened to people when they told me that!

I'm approaching the 10k mark with probably another 8 to go and the tailshaft back is all still stock! [emoji24]

Pushing on anyway [emoji23]

Appreciate it mate, I'm sure I'll have some more questions soon enough... I still have all that stuff for you when you get your MPVI

Done deal big fella

Big builds dont seem big initially but everything blows out

Great write up. Did you manage to work out the opening and closing points of the intake and exhaust on those cams.

I was going to get a carbon fibre driveshaft. I looked under my FG with the Manta twin 3" and there aint no way a single piece driveshaft is gonna have room. I guess the routing of the V8 exhaust is somewhat different. The Nizpro exh may have some room there??

pics of manta 3" lacking room?

Yea Tranna

That's all the opening and closing events and lifts at certain degrees..

Really? I'm assuming they have it made right, we will soon see

Great read!

Did you try measuring flow on the big port with the manifold bolted up Vs the standard port.

Wish I had a flow bench![emoji7][emoji7][emoji7]

No I'm gonna stick with the stock upper half, I have just gutted it out so it's essentially just an open plenum, looks stock, and don't have to modify any of my boost pipes

Does the stock upper half split the air evenly into each runner?

No we didn't captain, but I still can..

It will once I'm finished with it gaz,

The only reason I asked was because even though you didn't get any flow gains from the big port, you may get a ram effect gain once the manifold is on.

Are you thinking of fitting larger inlet valves (as the valve size seems to be the restriction) if that's possible?

Yes and no Captain, generally speaking a bigger volume port will be better, but the intake runners will be the governing factor, there's no point having a big port with a small intake runner, otherwise the air speed will slow dramatically as it enters the head, where as keep everything consistent with a taper on the entrance of the intake runner you will create the ram effect as you said... So we have worked out the the cross sectional area of the intake manifold runners and kept everything at 2.65".... So it goes from the plenum to an opening of 6.2" tapering down to 2.65" all the way to the valves...

I did think about it but had already bought the Ferrea valves and locks to suit ($900)... So I'll definitely do that in the next one haha
