I will Pete but what is going on with this place not graphs yet ?
Alright thanks Pete, it's hard work but managing to stay fairly stable. The old mans not too good at the moment, so just making sure he's ok really. How are you doing mate? I'm still loving the bikes instead of cars!

Glad to hear you're managing it James, you have the correct attitude bud. I'm all good thanks bud, been off work for 10weeks myself after an operation on my arm, I go back next Monday, can't wait

Wasn't totally off topic - I gave you the info you were looking for haha
So everything the same as when rich had it (when it was 470hp at the fly) except now you have the efr and manifold?
That graph you put up is at the fly?
Cheers Paul
That dyno is at the rear wheels, I have never run on it before to be able to tell you what it compares to on other RR,
It also had a very small fan so you could only do a single power run and then had to let it cool down or it would overheat.
So max torque at 5000rpm, is that any sooner than a gt30 would? Tbh it's not as early a pickup as I thought these efr's would produce not that I know anything about them I've just heard them recommended so many times.
I think id go efr 7670 on a 1.05 a/r jay if your still shooting for around the 600 hp mark, the bigger housing made a huge difference for my gt40 on the last rb26
My gtr has gt3071s with billet comp wheels so basically gtx I think, they are flat out at 478 hp each

Id love the efr 7064 karl but seeing as money aint growing trees lately it looks like gt3071.92 as at least they can be rebuilt if it shits itself where the efr can not atm

Max torque on that graph is about 4800rpm at the wheels
This engine is using a standard port head the turbo would be much better with head work
A 7064 would be a better spec for this engine

I hope so a bd15 inlet and a bd14 exhaust 25.5 mm inlet port and 24.5mm exthaust port so should do the job and I hope I see 400 bhp atw

Hey Karl long time no speak was just catching up on your GTR thread lol glad to see you are doing well .I will be moving onto modern pastures at the end of this year once I have finished the cossie into a mk2 frs as im getting far to old to bugger about with these old cars no lol

The ramp rate was set at a fast rate as the fan on the Rr was not able to cool the engine on the normal rate this will make spool later.

Same here mate these modern cars are so reliable it's difficult to see any downsides
