Yes it has been proven to work over dual pass for drag applications. That's why csf after selling 1000s of dual pass IM switched to single pass.
Don't trust me look at what every fast high hp application uses. If that fits your goals then that's the way to go. Most of these cars were on dual...
My burden of proof lmao. It's common sense. Same as me saying if you use a single M5 nozzle with your horse power you'll get the same if not better cooling effects. Do I have any data.No.
Go spend $200 for a spacer and get data if it doesnt effectively reduce heat within 25% of wagner ill send you the money for the spacer. You want data so bad heres a free way to get it :)
Again its been proven to work if you look at the history and evolution of CSF manifold. Getting the intake manifold off the block is common sense to reduce heat and heat soak.
Here is some screenshots of discussion since you cant seem to find them... (RAVI is owner of CSF)
You let me know what you want to see from MY data I am here to help you Razor. Im assuming youll want data from an oval track on a car that makes 500 whp but unfortunately that not...
Maybe read back at what I said and what you said. I said it would work for heat removal by getting manifold off block. Then you asked for data on charged air temps.
It would work for removing heat since the manifold would no longer be directly on the block. Thats been proven again see CSF the...
Sure but that brings me back to my point at those power levels you are talking about anything will work. So why not just spend $200 on a phenolic spacer. Thats where you are getting a ton of heat removal getting the manifold off the block.
It really is though. I know you are having good success with the one you are using but i dont mean this in a negative way, your car makes very little power. So yes for cars making low power any of the manifolds will work for them. Hell get a phenolic spacer and shove it under the stock manifold...
I have 2 original design EOS that was dual pass instead of single pass. Will still work well just not as well as the current version. Can get you into it pretty cheap :)
