You are right.

I may do a quarter block fill and see the results.

I have a 1m/40" diameter capacity DMG 5-axis that can do it. All I need is a cad model.

What is the machine time rate, non-inclusive of base material?

Who would be expected to do the tool path QC?

Machine rate...roughly $150 per hour. We are not the cheapest shop around but our quality is top notch.

I cut to a supplied CAD model. We program and verify our own toolpath. We have been in business since 1979 and bought our first CNC in 1984. We also have 8 axis Mill/turn capabilities up to 24" diameter.

I'm a born and bred machinist with 18 years cutting experience who believes in continual improvement.

Now, who has a model I can throw toolpath at

Attached pic is of a prototype cutter head for some deep hole drilling. Finished version of the piece in the previous pic.

If we can get 10 orders this Project may come through.
LSM systems engineering?
Dart?

They both have made blocks for things other then ford and chevy.

Also MAZWORX made one for the SR20 Nissan Racers.

LSM will make a block but at least 10 blocks must be ordered.

10 x 8.ooo usd = 8o.ooo usd

I could not find anyone else WHO wants a billet s54.

Do they insist on all 10 blocks being identical? Or do you get a chance to revise the CAD design for each cut? If you want to introduce reversional type changes for minor corrections or whatnot, having to cut all 10 blocks identically is a real waste.

Else you can plan to make revisions to the design and send them through as you gain further knowledge from your experimentation/test processes.

10 blocks at a time.

revisions will cost extra......

not an easy R&D

Talk to these guys, their E30 has a custom block S38.

thank you, looks amazing.

Sent them a message.

I started a S38 project back in 2007, built the turbo manifold to be used with GT4788, built the intake manifold. Sold the car as we found out the M5 E34 was wrecked.

Still keep the these S38 turbo and intake manifolds. I am a fan of S38 engine.

Yes. S38 is a great motor. I love big inline sixes like the Ford Barra, Toyota 2FE and Nissan TB. But the crankshaft vibration is a big problem. S38 with a perfectly balanced crank and close to 9000 rpm would produce some great numbers. I think a S38 with a new crank sounds more logical than making a custom block S54. It has material between cylinders and the rod/stroke ratio is better. The only downside might be the lack of VANOS, but you already deleted yours, didn't you?

I think there is a 4.0L Ford engine, sold in Australia, turbocharged...

Lack of vanos is a problem for the ones who drive on the street.

Why? Cause we need to change cam timing to make more torque and more boost at lower rpms.

I have been playing with vanos since 2006.

I keep Vanos on all of my 4 M3 Twin Turbos. All have Vanos running.

I have bought VAC Vanos Elimination Kit and did test on dyno dynamics.

1 bar ( 14,7 psi) of boost comes almost 1000 rpm later with the lack of vanos.

No vanos = No torque at lower rpms = No boost at lower rpms.


Now when we talk about drag racing at the track:
the drag racing engines/engine management systems build boost right off the line.

Imagine, a two step rev limiter, or launch control, or antilag, or whatever technique is used, in all of these cases the car leaves the line or takes off with 15-25 psi of boost pressure. So without the rear tires rolling you have "boost pressure". Once there is 15-25 psi of boost, it does keep on climbing.

Other than boost pressure, vanos does improve low & mid range power band.

Without Vanos, or without variable cam timing, drag racing engines' camshafts are dialled in for the 2/3rd of the power band. I.e the cams are dialled in so that they let the engine breath from 6000 till 9000 rpm. This is also ok for a drag racing engine as the engine does not drop below 6000 rpm once it takes off at 6000 rpm. At each gear change REVS are kept at over 6000 rpm.

For a drag racing S54/S38 or any engine, vanos is not a must.

For a street driven engine vanos is a must. I do keep Vanos on my S50B32s and S54B35s.

Add to that a set of cams custom built for a turbocharged S54. Rev it 9000 rpm. That was my route to 4,23 s 60-130 mph

^ I figured you removed it. I agree with you, VANOS is a must. I drove a stage 3 VAC's with VANOS delete, and even though up top it was crazy down low it was gutless. Coming out of corners would be a disaster if you forgot to drop a gear or two. Something that with VANOS would be less problematic.

yes, vanos is a must.

add to that a set of cams and head work....
