I tried to find this before bothering anyone, but no luck: I have John's Blue Thunder intake on my mild 312, but I am very interested in how it compares to his new hi-rise intake with that cool logo on the top.  Is there a thread somewhere that I missed that gets into the subject of comparing the performance differences between the old Blue Thunder and the new intake (don't know what it's being called at this point) intake?  Also, are the Blue Thunder intakes still being produced?  Many thanks, Ron

I had the same question, John told me that the performance difference wasn't enough to warrant buying his new manifold.  If you don't have a one of these, I would buy John's manifold as it is of high quality and available.

Genuinerod:  Interesting.  I have been running John's Blue Thunder intake on my 312 for a few years and it's working out fine.  Not sure why a new one would be put out there if it's not a performance improvement over the old one, though.  Maybe John will spot our messages here and leave us a brief explanation.  I sure like the vintage looks of the new one with that nice logo on the top.  Ron

Is there a waiting list or is John's available now?



Tbird low rise and valley cover with road draft/pvc port also?

I think John jumped in because Blue Thunder was not producing. Last time I checked no one had any and didn't know when or if they would have another run. You just have too give John a call and if he is out of stock put your name on the list. I know that he has been tied up on the alum heads for several months now so maybe a little wait.  I love my Mummert intake and had alot of positive comments on it at the show this weekend.

Glen:  What's he calling the new one?  Does it have a name like "Blue Thunder," or something similar?  Ron

I think there is some confusion.. John was not the manufacturer of the Blue Thunder intake. He was a dealer for them. Blue Thunder also produces intakes for FE and other Ford engines. Availability of their intakes was always spotty, so I think John jumped in with his new design

John and maybe Ted may have some hard test data on the BlueThunder vs the Mummert 4 bbl intake. I was a very early adopter of the BT and at that time John said that he had done a lot of the development of the design and that his intention was that it would fit an unmodified T bird hood while taking into account the lessons he had learned porting B iron manifolds. But as others have said it was actually manufactured by somebody else. Now I think that he has taken his earlier work and adapted it to the design without the heat crossover. I have not compared it to a stock B manifold or the BT (which is the same height) to see if it is higher rise but there are several people who have both and could probably tell if it is. The biggest advantage of the new Mummert design over the BT may be that it has a large air gap underneath and so gives a denser charge. Plus of course that cool logo!!

Doug T: Your post answered a lot of my questions, so thanks for that.  There seems to still be a market out there for the BT intakes, so I might bite the bullet and put my name in for John's new one knowing that I can probably sell my polished BT to help cover the cost.  First I have to figure out hood clearance issues to see if I want the low rise or high rise.  I think for my 1956 Club Sedan John is recommending the high rise, but I'll double check that before I write a check.  Thanks, Ron 

Guys, I know alot of you are limited by hood issues, but Ted has done alot of dyno work with differant spacers. I think he is doing an artical for a future issue of YBM so I want let out the details. It seems that the Y block likes alot of spacer, but not just any old four hole spacer. I know that it might be hard to believe, but the one on my engine was good for 37 HP and I have the dyno sheets to prove it. So if you have room for a spacer, you might want to give him a call.
