New Remmele Type 4 Billet CNC Heads "Light Version"

[SuperRSi]

So what do you think the performance or flow difference is between the light Remmele and the Thorsten Piper heads? I ask this because I know I can get one of them...
I have 102 Nickies so need the light.

I don't know what Thorsten's heads flow. They are very nicely done though. However,they are more expensive than the light heads from Remmele. The light heads have more cooling surface also. I personally do not like a D-shaped exhaust port. The reason for a D-Port is to eliminate reversion from the header during valve overlap. However, a round port has less friction and provides more flow. The light head's exhaust port is slightly smaller in diameter than the header. The wall around the port will block reversion. The light head flows 284cfm@25 ", which is good for 270bhp NA. I would guess Thorsten's heads are about the same. The biggest difference is the price. The light head costs 2490.00 Euros complete with nimonic valves,seats,guides, ready to run. Thorsten's heads cost IIRC 2990.00 bare without seats,valves,guides. Remmele does everything in house,which is what makes the difference in the price.
Wally set the benchmark for a reliable and powerful type 4 and will do so again. I'm convinced he will shatter 500 hp easily at the same boost level with less head and intake temperatures. I am planning to be on the road with mine in 2016, but have the car basically done this year. I don't think that I will be able to keep up with Wally,my gearbox that I have is too weak. But I will beat him in beer drinking

I do have another set of 105,5mm Mahle forged pistons and Deutz cylinders ready to go. But,I would have to sell the 102mm custom JE pistons and the matching Deutz cylinders. I think it would be hard to find a buyer for them.

How much for the 102? what piston pin size.

[70Turbobug]

The pin size is 24mm standard type 4 pin size diameter. Are you interested in the pistons and cylinders or just the pistons?

[vdubzack]

both, cylinders and pistons.

[70Turbobug]

I've decided to keep the 102, since they are custom made for my engine.

[SuperRSi]

Are you holding out on the new pictures? Or will you debut things as a complete engine?

[70Turbobug]

LOL, I haven´t gotten round to transfering the pics from my phone to my pc. I measured my Deutz cylinders and found that I need to have them turned down a hair. The cut out in the head is 115.08mm and my cylinders have a diameter at the top of 115.92mm. There´s always something... . Once I have that done, Ican put the engine together. hopefully, I can get the cylinders done befroe I go on vacation on the 31 August.

[SuperRSi]

I am looking forward to your vacation!

WAIT! I have to wait until August 31 for treasures? Oh Man...

[SuperRSi]

Are you going aluminum or steel pushrods?

[70Turbobug]

I will get your packages out with UPS before I leave for vacation. That's a type o above, my vacation starts July 31. I will be using Gene Berg chromo pushrods.

[SuperRSi]

Do you think that a Manton tapered 7/16 to 3/8th pushrods would fit?

[70Turbobug]

They will fit no problem!

[SuperRSi]

Finally getting around to building my engine with the Remmele one piece heads. I will keep everyone posted...

[70Turbobug]

Sounds great!
