Looking for the

1.) Runner Flow Coefficient

2.) Runner Flow Attached to the Head (stock head)

3.) Runner Length

4.) Runner Diameter @ Head

5.) Length of Plenum

6.) Width of Plenum

7.) Depth @ Side of Plenum

8.) Depth in Center of Plenum

Need these specs for EA Pro v3.3. If anyone has a definition file they can e-mail me that would be very much appreciated!

 

Have you tried contacting TPIS directly? They might just have the information you are looking for. I contacted them when designing my Minirammed 385, and they provided me dozens of tech tips over the phone. Good service, in my honest opinion.

 

They should be in the example intakes to choose from...

 

I'm very interested in knowing these things too. As for contacting TPIS... yeah right. First, I would hardly expect an unbiased answer from them and secondly, they seem to be kinda, well, let's just say I don't particularly like them. I was considering swaping my LT1 intake for a miniram and have been wondering if it's really worth the effort. This in would really help in the decision.

They should be but they are not unfortunately

One thing too, my gut feeling tells me that you probably wont see a large difference between the Miniram and an LT1 intake manifold, unless you are getting into big intake runner ports on aftermarket heads. There are differences in runner length and plenum volume between the two, but I dont think it's significant enough to show up except on an extensively tuned engine. One significant difference is that the Miniram is an air gap intake whereas the LT1 is not. That might make a small difference.

I Was Checking Into The Miniram And Was Told By Tech At Tpis That The Minimal Gain From The Miniram Compared To Lt1 Intake Was Not Worth The Price. Also Told That The Miniram Was Made To Replace The Tuned Port Set Up With The Outside Runners And Made A Considerable Difference In Hp In That Situation.

 

Turn off your "caps lock".... when the board software see all caps, it does exactly what your post looks like, capitalizing the first letter of each word, making the post difficult to read.

 

I had this same question a while back. Still no answer on it yet but I was looking for specs of a stock manifold not the miniram. However, they are similar but the miniram is a better piece to be sure with more plenum volume and slightly longer runners (.5" but every little bit helps). However, TPIS' prices would never make this a worthwhile addition. Most do the converted LT1 intake on tpi b/c of the cost diff.

 

I tried to search at corvetteforum, but the search function in the archives isn't working right.

I think I remember a guy named jeb burnet cutting apart a miniram, porting it, and welding it back together for more flow to feed a 400+ cube motor. I think he got 330 cfms out of it.

Try and do a search and see if you can contact him. He might have some specs from the miniram work he did. There are some guys that have made their own single plane conversions over there also, they might have some specs also, so do a post over there and see what info turns up.

 

All I can contribute is one case where an LT1 intake knocked 25 cfm off a set of 280 cfm heads when bolted up.

Far as the intakes you probably want to specify which casting LT1 intake as there are differences. I would agree that comparing the Miniram and LT1 intake is pointless, going to be VERY similar.

 

Was that a stock untouched intake? I hear the stocker knocks airflow down ~12%. Not sure what a fully ported one would do...perhaps Lloyd can chime in.

 

Yes, a stock untouched intake knocked 25 cfm off. A fully ported LT1 intake with the "right" porting (not just gasket matched) only knocked off 15 cfm. A victor jr. barely changed the flow at all.
