This engine is a prototype flat four being built by JT,
and Greg Anderson from Pro Machining Ltd in New Zealand.
http://www.pro-machining.com/
It will be 2700cc using a 84mm stroke crank that has 5 main bearings,
and uses a roller camshaft with 60mm main journals.
Heads will be also a custom item from Joe Deppe in Indy,
and the guys will be able to use digitized progamming to CNC the inlet and exhaust ports
to attain flow levels of US pro stock cylinderheads.
Awesome stuff, and so close to home....can't wait to see those heads!!

impressive machining.
one question though, why start with a whole new block and crank when the new subaru EJ25 produces 300hp from the factory (I know it's turbo but even still)? Wouldn't 16 valve heads and a stroker crank in that motor produce the same horsepower at a much lower price?
Is there a 2v per cyl limit on the class or something?
Also, the Subaru already has 5 bearings in the block.
Just a thought...🙂

I have never seen a fast N/A Sube( although they should be on paper).
This class is generally a normally aspirated class, and has restrictions in capacity for boost, or 4 valves per cylinder.

Essentially, we started this project because JT was telling me about the problems he was having with his current engine. The whole engine block configureation was at its limit. So we decided to go ahead and try something ourselves.
WE are working on the heads at present and will have some photos available shortly.

Still having the odd problem getting logged on. Seems to have a lot to do with the time of day. Anyway....
Here are some progress photos of the Crank. Only needs oil holes, lightening holes through bigends and heat treating/grinding now.
We have managed to get the weight down to 25.5lbs / 11.59 kg.
The head casting shown, is our second option and has been supplied by Joe Deppe of Indy.
The head casting of our first option will be ready next week. Will have pics then.

For today's update, here's a shot of the barrels.
The plan is to have these done by the end of the weekend and start getting the heads bolted up next week.
There's going to be 6 studs on each cylinder. We want to make sure we keep it nicely sealed. ;D

We've got the head back from casting. Nothing to show there just yet. Hope to have some machining done on this over the weekend.
This is one of those projects that is done in our "spare" time. We would really like to get this project done a whole lot sooner, so anyone out there has any thought on where we can get funding so that we can work on this full time. Any ideas would be gratefully recieved. We don't want this turning into a lifetime project and never getting finished or realising its full potential.

dare I ask, but what sort of $$$ buys this engine?
also, it there any cooling to speak of, or is it strictly a drag thing.

promach ·
We don't have dollars worked out yet, but will let you know when we do.
There will be fins around the bores to help with cooling, have to look at the cooling around the intake/exhaust later. Running the motor on alcohol helps with removing a lot of heat.
The first motor will be going into JT's midget. This is purely a straight out race motor, not necessarily just for drag.
With the current bolt pattern in the head, 4.6 pistons are no problem, if I push them out we can have 5".

Guys I'm trying to get JT's login sorted - he is having trouble signing on which I Think has something to do with conflict of email address (see sticky thread in general chat section from vanderaj).
I've contacted Andrew so hopefully we can resolve it soon so JT can post his input here.

hey Dave we have found some material ,alumec 89 a Swedish material with better properties than 7075 and its on our doorstep and cheaper to ,sounds all good to me . did you see we had a response from don pauter that was a good boost i can tell ya and he doesnt mind if we bounce ideas between us ,we wont be giving to many secrets away you never know what he will do with them 😂.the head will be on its way to rader racing in San Diego, California to have the ports finished of . the plan is to have john rader work them up were they can be used on the 4.6 - 5" bore .when we get them back we will get them digitized then finish the machining. the crankshaft just needs the oil holes put in and that can go for heat treatment and then ground and finished .thanks jt
dangerous ·
Hi JT and Greg,
Good to know you were able to source some material.
NOW. What are you making with it!!??
That is a great contact to have with Don Pauter.
Treat him well and he will give you the shoes off his feet.
You can both gain by the association.
People in the past have taken advantage of him,
so it is refreshing to see that he still has some "bounce".
Looking forward to seeing those heads Dude!!

We have been making slow progress, have the barrels up in the mill right now to finish cutting the cooling fins .Got the plate for the main caps on thursday also have to make a fixture for John Rader to bolt the head down to the flow bench for him to do his "thing" . Starting to look at using software to take the heads to their full potental instead of doing by "grinding and grinding" away .the software allows the user to make changes then reflow the heads, once done take the model and convert it into code for the mill .You have to thank god for the 21st century
dangerous ·
That sounds pretty good Greg.
Does that mean you can get John Rader to do just one of each port,
and then mirror them for the adjacent cylinder?
Is this particular head going to be for the 4" bore?
How's those crankshaft oil holes going?...joy!

All we are having John do is one set of runners , then will have them digitized , make that into a 3d model run it in the software to see if it can be improved, mirror it, import it back into my cam software and thats all she wrote
Yes it will be used on the 4" bore but are making it so that it can be used on the 5" bore if so needed .Later will look at a overhead/twin cam head set up ,this opens up the area of beening able to make a crank with a "big" throw on it
