FE Intake Adapter

[XR7]

That looks good Barry, thanks for posting those pictures and info. John sure can weld aluminum better than anyone I have ever seen.

Also Jay, your BT MR adapter sure came out nice, good job on that, using the HR base to start with (and lots of machining!). Those BT MR port are BIG! Two solutions for the same issue/application, kudos to both of you.

I would like to build something like this for my adapter.

Blue thunder and Dyre's Blower Service have them already made up.

Although I often say it to myself, I think I also need to say here that you and your efforts are 'cooler than spats on a duck'!

This isn't the first test Ive seen that a Tunnel Ram outperformed the other Street Style Intakes ( Car Craft did it with a Big Block Chevy Years ago ) , BUT what is missing here and the other tests were the street Manners ( kind of like no reason for a Dist recurve for racing ) your tests Start above what most street combos cruise at 3000+, This is where you don't drive a Dyno analogy fits , If You hook a tunnel ram to most combos ( that are truly street cars ) Not Drag Week participants ( no offense meant ) and they will be Dogs,  Lazy under 5mpg under 20mile trip fairground cruisers, 4000+ Stall Converters and gearing really needed for That intake to work well ------  With That said I love your adapter  , I have been looking for a Blower intake for a Cleveland , These Tests are Great , saves the rest of us Dyno Time , Thank You Jay

Don't know where I was when you dyno'd the 351C manifolds on the adaptor but I missed it...Was the performer port matched or left with the slightly smaller ports...I found the video with the clear valve cover interesting...Not as much oil as I would have thought....Cory

Glad you like the tests, Faron.  I like them too, because they are so much fun to run   I wish there was a way I could run a dyno test down to 1000 RPM to address issues like low RPM performance of a tunnel ram.  I think there's a lot that can be done with carb tuning to crutch a tunnel ram's performance down low, and I also think that if you convert it to EFI with the injectors down near the ports nearly all the disadvantages at low engine speeds go away.  No way to prove that out on the dyno, though...

The Performer RPM was NOT port matched, and since the adapter has medium riser ports and the engine has CJ heads, there are two dramatic port mismatches on this setup; one between the adapter and the head at the port floor, and the other at the intake and the adapter at the side and floor of the port.  It amazes me that the Performer RPM did that well with those mismatches in place...

when my tunnel ram is finished did you want to test it? I could send it out? lol

Interesting as the torker II port is very close to the port you supply the adaptor with.I think the performer port is about .100 narrower and .400 shorter...The difference in torque has me thinking about using a performer as my car is strictly street driven.....Cory

I wonder if this would fit on the tunnel port adapter?

Too bad the ports are rectangular where they meet the heads.

Hmmm, probably a longshot...

At 37 pages, this has probably been put out there but this might be an interesting setup.

Jay, any progress updates on the high riser version of the adapter?

Add an upper like this and you would be good to go.
