Hey its me again! What can we expect to gain with a ram air intake ? Is it worth the effort to locate and buy this,we need the piece that is mounted under the hood,we have the air cleaner part.  Hans Olsson. ------------------

Yes, I believe it is worth it. You know you can buy a reproduction plenum from National Parts Depot or Glazier's Mustang Barn for $125, then instead of the flapper valves, fabricate ducts to mate the scoops to the plenum. I'm planning to do that very mod to my Sprint. I remember when I had my stock hood I cut a hole in it, put on a velocity stack on my Holley and mounted a 7" snorkle hood scoop and you could really feel the difference! Currently, I have been running my NASA hood without the scoop block-offs. ------------------

Ram-Air is worth at least a tenth and 1 to 2 MPH in my opinion, We have tested this though and I'm not telling you to spend your money unless you think you need to pick your car up this much.

Steve,it sounds like a good idea and at 125$ not to much money,can you help me with the phone number and/or e-mail?  . We need to improve the et,we can only run under the index on a good day  .Our best is 11.92 -0.08.Maybe we should ask for a hp reduction from the nhra  . Perhaps our car is better of in the ihra? Or do they have the same ratings.Thanks for your reply Mark and Steve. ------------------

Hans, NHRA and IHRA share most of the same HP ratings for Stock and Superstock. Your combination has just been hit by 10 HP in case you were not aware of it.  Instead of 285 factored HP, it's now 295 Hans. You would be better off writing to IHRA for a reduction as they are more apt to listen, but due to the amout of very fast 73 351C cars in stock eliminator, I doubt it. ------------------

Alex,our motor is the -71 351c 285/320hp closed chamber 4v.I dont think anyone is running this combo right now,so no risk for getting hit as of now. If someone has any experience racing this motor please let me know (best et mph or whatever you can think of),with the low lift .430/.450 is it a dead end? Hans

Oh, sorry Hans. I thought your car was a 73. (you know all of them 71-73's look alike lol ). There was just a request to the NHRA about HP reduction on the 351C 285/320 during the recent review. It was DENIED! They sighted lack of current competition data as the rational Hans. I suggest that you contact Len Imbrogno at [email protected] and ask that the reduction be reconsidered at the next review. Tell him that you can provide time slips as they would like to see them. ------------------

It was a gentleman by the name of Don Bowles Hans. A little yellow car (71 Mustang Mach I) called the Coal Digger from the 70's and early 80's. He had a crew chief and engine builder by the name of Jack Roush. Sound familiar?  ------------------

The name sounds indeed familiar.I got my NPD catalog in the mail box today This is just to much,i had no idea of all the parts they have.I will buy the plenum,but i am not sure about the flapper valves,at 349.95 is pretty expensive.Perhaps steve has the right idea,to make ducts that connect the plenum and the nasa scoops in the hood.
Later.. Hans.

We did some work on the ramair this weekend and it was easier than expected.In place of the flapper valves we made ducting of aluminium sheet.The ducts fits thigtly to the scoops and we plan to seal them to the plenum with foam rubber.Even the holes in the plenum for the flapper valves can be used to secure the ducts.Two small sheet metal screws on each side.Thanks to you steve for pointing out NPD.

My pleasure. Do you use an air filter? If so, what size are you using? I was wondering if my 14x4 air filter will fit in the opening. ------------------

Steve, we will try with a filter and if the car runs good it will stay in place. I am not sure what size will fit,but i do not think 14*4 fits.I will measure it tomorrow,and let you know.Perhaps our local ford dealer has one in stock . Hans.------------------

Hans,That filter size that you specified is the same as a certain Fram part # that is the stock replacement air filter element. The 13" chrome Motorsport open element breather uses the same part #. I have that breather on my 383W stroker in my 69 Fastback. I have a part # for a K & N filter in that size. Basically had to go throught the K & N catalog looking at the dimensions. The filter that I have used for the past 3 years is this K & N. The application was from a Mercedes!. When I get home from work tonight I will get you the part #. Since you only have room for a limited size filter the K & N may help you out as the restriction is less than a paper filter. A pic of that filter is here:

The filter is a K & N #-2865. It is the same size (about 1/8" shorter, but same diameter) as a Fram CA340A.The CA340A is the replacement element for the 13" Motorsport breather and also fits most early 70's 351 cars and trucks. Later, David Cole
