    1992 / 1999 4.0 Head swap

    Those monitoring aspects like air intake temp are great, but wouldn't I still need to get a programmer for tweaking the pcm to take advantage of the compression change to 10:1 with the 422 comps cam, bbk throttle, heads ported & polish with expanded exhaust ports, jba shorty headers, upper &...

    It's an older Street Smart Design with a carbon fiber shield box, air comes in from underneath, but it isn't totally sealed

    That make sense Dirtman, i do get your point, thanks Mines an old street smart design which has a carbon fiber heat shield around it, it pulls air from the bottom of that. With raising my compression to 10:1, the 422 cam, BBK throttle body, shorty headers, head ported & polished with exhaust...

    Did you have to send your PCM to them, what other MODs did you do, how much HP increase did you get & how much did it cost ?

    Everyone has an opinion, so what I do is to ask the questions & then test & evaluate for myself. Actual testing & results, are reality. But in this case, I would agree that it depends on the application of stock vs what your actually testing with. Here's an interesting read Performance CAI...

    A cold air induction system could help, test pipes :) where your CATs are, a change in tire size & possibly a little more air pressure in the front tires could all help. And oh yeah, non-ethanol fuel by itself helped about a mile a gallon for my 98 4.0 ohv ranger

    Curious on how much intake air temp affects your performance & how that might be measured? Also I remember a MARCH RAM air I used to have with my '89 Mustang, it had an intake scope which brought in the air from underneath the car, wonder if there's anything like this for a Ranger?

    Any thoughts in respect to using a MAF from a 4.0L SOHC (65mm) supposedly bigger, then the MAF on my 1998 4.0L MAF OHV? Would this work without a programmer? Does this make much of a difference in performance?

    Good to know, I was just considering air flow, & not air temp, sounds like I probably do need to get the coned air filter back in a air box to get that temp back down. How did you go about getting a reading on the intake air temp ?

    1992 / 1999 4.0 Head swap

    I already have the bbk throttle body in place with araide cold air induction but air box removed leaving an open cone filter. I've been thinking about a MAF meter from a 1999 sohc but don't know how much bigger it might be compared to my 98 MAF on my ohv, or how much difference it might make...
