Ported Lower intake

subscribing... can't afford to port my lower intake yet but would like to see some more results
Nazman, what type epoxy are you using for the floor of the manifold? I ported mine but don't know what type of epoxy to use.
Just use JB Weld, it won't go anywhere.
Here's a newsflash.
Air hates a "male" radius but a "female" radius isn't a killer. Yep, you heard it here first. Think of a pickup truck. Sit in the bed and spit up into the wind. Yep the spit will stay in right? Now stick something up that interrupts the airflow......... Just think about it. Why add epoxy when there are plenty of places to cut?
I'm out of here.

Dont.
It will eventually fail.
There are some very high quality industrial epoxies out there that will last a lifetime.
Cutting is not always the option, as in bigger is not always better.
Filling some areas will yeild a much better result than "cutting", again, everyone has their own techiques/methods and for each, they will get diferent results.

I ported my lower intake and heads and there is no longer a transition at the heads/intake, it's just a straight shot from the lower intake to the valves.
I too am a home porter of the lower intake. I have seen one of naz intakes and for the time it takes to port your lower intake, his intake is worth the money. Naz's intake is a very nice piece.
I'd still like to see some solid results from this. Like some datalogs and dyno pulls to show the difference. I know Naz has ported several of these now and the only results we have were typed with nothing to show the gains. Not doubting there are some gains to be had by any means but I'd like to see the overall change of the curve and intake temps etc. I did a little bit of work on mine in the past, but not anything enough to make a difference. If there are some legit gains to be had I'd really consider taking it back off to have Brian or Naz and have them really port it.
I had all the info on the last car I did the Naz swap on. IAT2 temps, boost change, a/f change, and before/after numbers. I gave all the info to Naz and dont think I have it anymore. I hope to get mine done soon also to have more data to add. Looks to be done in about a month.
How do you expect to market your skills if you do not give anybody some numbers and datalogs. I would be alot more interested if I knew what some gains where..........
He has a website with gains posted.
I did not see any thing for an 03-04 cobra. Just a 99 cobra I believe. What is the website
I seen these in the beginning.
Before port: 370hp/ 359tq at the rear wheels
Starting Temp IAT1: 100 degrees, Ending Temp IAT2: 120 degrees. Boost was 12psi dropping to 10 up top.
After port: 389hp/ 375tq at the rear wheels
Starting Temp IAT1: 100 degrees, Ending Temp IAT2
114 degrees. Boost was 12psi dropping to 10 psi up top
What is the only modification a quite large supercharger pulley and a intake port. This is not very much information to go and spend 400.....I want more than that. Only 6 degress. come on These numbers dont seem right compared to the boost
Thanks! Yes, we do put lots of hours on our Terminator intake ports and they deliver huge gains! Lots more than what is on the website!!
Sorry we no longer post "detailed" pics of intakes (B, C, or Terminator intakes, heads and/or Ported Short Runners....)
For the folks....FYI. There are over 10.....High Boost (25PSI) KB/Whipple cars running Nazty Lower ported intakes on their Terminators on www.modularfords.com alone and over 1/2 of them running 9s...just FYI and several more with stock or ported Eaton units and lower boost levels with similar results!
They are.....and very impresive gains!
You mean to test? You have your Nazty Ported intake on hand......:rockon: looking for some data on your beast!
There are not "some" gains...we are seeing over 15+RWHP/TQ on STOCK non-ported Eatons.....quite a bit more on TS blowers...quite a bit more!
Take this as an example:
When we get inquired in regards to our Nazty Ported Short Runner (NPSR) intake we will sell it as a 25+RWHP gain @ 6800RPMs....were in reality they are making 50+RWHP @ 6800RPMs (more than any other single mod other than Nitrous or FI).
We MUCH rather go conservative....and lose a few jobs.....and make lots more "actual" hp and have "happy" Nazty customers!

Few things to keep into consideration:
Intake was one of our early, early design (read: research)
Current intake work......= Day and Night diference....If I were to put a number on it...Ill say 3 being the intake on the test......75 being our current design....and each and everyone we do....we keep inproving them!
You may say that 19RWHP/16RWTQ is not enough along with 6 degrees AIT2 temp drop...but this is a stock blower with stock pulley......not being overworked or run to the limits like most of SVTP users run thier cars!
Even then....with that early intake design...you are looking at ~20 bones per HP gain! Which when compared to a blower.....lets say a Whipple 2.3 at same same boost level.....the intake will out power the blower by a huge marging when doing the $ per HP mod.
On higher booot applications the HP/TQ is increased and AIT2s drops are much more significant!
Ill be glad to help folks!
