Not sure, will let you know when I know.

Strangely enough, me neither :rofl:

Master Jeff's secret to success involves a completely different location of the port, significantly larger, and a tapered runner design preferably to get more flow. Templates are on their way back to me, and we are going to cut a custom flange and probably some CNC'ed runners. Old manifold would have been dandy for your everyday 8500rpm 700whp monster, but making power at 9500 requires some tricks to be unleashed

Why did I have to watch this? Now I'm scared for my timing belt... watch it at 8:15.

Apparently chains have their own set of issues at high RPM. I can't win this game :(

Guys, here are some pics of the head progress as of the 19th of September... :hide:

I've been busy! ... with my BMW :hide: :idunno: :hide:

Plus, I think it's good to spread the updates out :)

From Jeff:

"Chamber Work Starting - Area to be relieved around intake"

Image


"Rough cut to scribe line - intake relief. 10 of these cuts needed per head"

Image

"Same cut opposite valve - don't worry these seats are coming out."

Image

"Opposite valve partially open"

Image

"Stock chamber - exhaust valve shrouding - 25% of valve"

Image

"29.5 Ex.Valve with clearance at chamber wall"

Image

"29.5 Valve - opposite. There will be more material removed when big seats are installed."

Image

"34 mm intake with finished relief."

Image

"Finished relief - no valve - stock seats can come out now"

Image

"Current shot of test port in development head - big seats now in."

Image

Since then, not much has happened. The next step is some custom valves from Ferrea. This might just be the highest flowing AAN/3b/7a head of all time when it's finished... Pretty cool! Jeff Gerner :hail: We shall see when the numbers come back!

Truely impressive :o

You will have to set the idle at 3000rpm not to choke with a head like this ?

That's sick. I like this project. Why is it taking so long, what, are you out of money or something? :P LOL

The idle will probably be a fair bit higher than stock, but I don't foresee it being higher than 1500 RPM. I really don't know though... we'll see one day!

LOL no, the money is just waiting to be spent. Most of what is taking the head so long is because Jeff is doing a lot of development work on it which will go into his own engine. Also, he knows I'm not in a rush, so the work is being done when there's time for it (it's not first on the priority list). That means more effective R&D and keeps the cost down a little I suppose.

Money influx is certainly not what it was in the past year, so I'm not trying to push anyone to get anything done. I'd be perfectly happy if it took another two years ;) I'm keeping myself plenty busy with sorting out the 635csi as well as with formulating plans to turbo it!

Yes :)


And no, haven'tdecided on the cams yet. We ccan't until the final flow numbers come in. I'm sure they'll be custom cats though.
