4000hp Hel short block test assembly ready
with correct clearances!
Our custom billet titanium connecting rods ended up
having to be a little beefier than our initial placeholder.
So we have to manually clearance the block to give at
least 2mm clearance. Batch 2 blocks will have this
detail fixed.
Doesn't look perfect, but it's structurally ok to
manually clearance here, passes customer use
approval.
Long block getting ready to go together also, first head
fully assembled in spec!

Introducing our Billet Merge Collector 'What could go wrong?' durability guarantee!
1 free replacement, regardless of how it broke. Just send us the pictures/videos and permission to use them. Full terms on the TOS page on our webshop.
So what happened in this customers case?
Based off the images it looks like a combination of factors. Vibrations and thermal expansion loads from the wastegate exit pipe transmitting though the wastegate to the wastegate mounting. High temperatures due to thermal insulation and likely closed floor (time attack car) with minimal airflow around the exhaust. Sharp edge on the *inside* of the wastegate duct to the runners/turbo area. Lots of heat cycles and use.
Due to customer time constraints to get the car ready for the next event, we sent out a replacement collector of the same dimensions, but updated model with filleted wastegate exit (yellow highlight in picture, all our newer models have this update). Other option was to make a custom one from 316 or 321 stainless material, but this would have taken a few more days for raw material lead time.
We also recommended changing out the slip-over fitting for a flex piece. And incorporate a external support clamp between the wastegate and main exhaust pipe.
And if possible, any slight increase in airflow around the header pipe would help reduce peak temps and thermal cycle load.
We think our 5 axis Billet CNC Merge Collectors are the most durable parts available. But sometimes things can happen. If it does, we have your back. And will try to help you avoid another failure.

4000hp v6 first engine assembly progress.
Rods, bushings, pins, clips, pistons, piston rings. All looking good. Tested for rotation clearance in the crank case earlier.
Custom tool to mount piston pin clips in the bottom left of the picute. Crazy stiff clips, hence the need for a tool, but should stay in there even at max rpm (well above 11,000rpm)!

CNC toolpath update for the 4000hp Hel billet tool steel crank looking mint!
No more small corners left over here and there. And much more reasonable tool wear.
Bearing surface polishing/grinding should be much faster and easier also.
The surface shape around the highest loaded areas is especially critical for longevity in a crankshaft being pushed as hard as this.
Peak stress needs to be kept in check, but for longevity it's even more important that the stress levels don't change too rapidly, as that aids crack propagation/fatigue.
This is why our crank designs have a almost organic shape. With the power density we push for in our designs there is no other way to make this work. Design time is crazy high (compared to basic cranks), but absolutely needed.
And the CNC machining side then needs to be able to effectively make these crazy shapes. This also takes a lot of skill and dedication to achieve.
The up side is that at least design criteria wise, we can push these crazy high power densities that are unheard of from other OEM's.
The only reason we even attempted this was how well our Thor crank has performed. Giving us confidence in that we at least know a little about what we're doing.
There are no guarantees in racing or when pushing boundaries. But it's what we love, and what we're good at.

Our new lightweight easier to weld version of the 4-to-1 parallel entry billet merge collector! Standard version recommended for all use cases, lightweight recommended for drag racing.
Central spike has much lower heat conduction in the lightweight version, which may cause overheating in prolonged high temp use.

Hel cylinder head getting ready to go on the short block!
The recipe for making maximum power: biggest possible bore to be able to fit the biggest valves possible. Keep port area transition as smooth as possible, taking valve guide into account, for minimum flow disturbances in the transonic flow regime. Highest possible cylinder pressure at the highest possible rpm.
5000cc 4000hp vr38dett replacement engine.

Well that's not going to work 😆
We may have slightly miscalculated the chain length.
Nr 1: order the correct length chain stat
Nr 2: figure out why we calculated it wrong, and try to cost effectively reduce the chance of making the same mistake again

First test assembly progressing!
Need some different heads on some of the bolts, and still a few small parts missing. But all major components fit together with correct clearances so far!

Close up look at how hard we pushed the design on our 4000hp Hel engine.
Intake and exhaust valve guides are fully integrated into the port design. And the port cross section area fully takes this shape into account.
The exhaust value guides have a shorter external end taper and different internal diameter for the tip to reduce the temperature of the tip. But still needs to be very close to the valve head to get good heat conduction and valve cooling.
Intake side is fully contoured behind the valve guide hump to reduce turbulence.
At full power both the intake and exhaust flow is mach limited during the entire valve open period. Shapes and maintaining port cross section really matter to help reduce shock waves and port flow losses close to the valve.
