Hey guys im wondering i live in mexico and in my city theres no place to make a dyno test so i was wondering if somebody here could give something aproximately to see how am i going o got the next things:

Neon rt 2001
comp cams 400
injen cold air intake for r/t
mpx underdrive pulley
kirk racing headers long tube
2.5 inches cat back
no muffler no cat
port and pollished head
16' wheels
mpx throttle body
Mopar performance wires

So i was wondering what could be my whp at this time anyone who can give my any idea?

what would i need to get close to 180whp

Cran 14 or 005, AFX PCM, and a better Long tube TTI or OBX. And most importantly of all some ITB's. IMO

A header is not going to add that much HP.

Take a look at this thread

Takes a lot to get that far without boost

A buddy of mine dynoed 179 with a ported head, crane 14, Fast fabs LTH, and ITB's. The bottom end was stock and the PCM was stock. IF you throw in a cran 005 or a AFX PCM you should be golden to hit 180.

And your compelatly wrong about the Header. An engine only flows as good as its most restrictive point. In his case its the shitty Kirk header. I have had one before. The primaries are just too small. It will be decent on the low RPM but in the high RPM it will be verry restrictive.

Oh really, so what do you predict a header would gain with and without supporting mods?

BTW 180whp is no prize IMO, it's what these should have come with stock with their weight

At their weight? hahahahaha

Remember these econo cars.

Headers are mostly defeated by the zero overlap cams that are stock (except the '95 cam). With out overlap there is no pulling the intake charge in via scavenging. Get a cam with overlap and the gains from the header come into play.
Of course so does unburned fuel influencing the o2 sensor. But if there was a way to pull CPS timing at low rpm that would be a non-issue. There would just be clean air flowing past the valves.

mini threadjack, ITB=?

What's so funny? You don't think 130 @ the crank is lethargic for these cars? Compared to a 1st gen these things feel like tanks when floored

Well that is a much better explanation. So you pretty much run rich if you throw a cam on there?

bump for this

Individiual throttle bodies. That means one throttle body per intake cylinder.

The OBX should work fine for an R/T. The bolt patern is the same only differance is the ports are bigger. I'm pretty sure the OBX ports are big enough.

so there should be no problem with the obx on an r/t anyone who was a rt have one of this?

a bump in compression will help...not sure how much, but 10.5 would be nice.

Don't forget an afermarket intake mani might be a good thought. Wait, nevermind, he has an R/T. You should have your intake P&P'ed to flow better zeRk_RT; but again to get the MOST out of it a cam is absolutely necessary.

And to Adionik, I'm not sure if that's sarcasm or not, but installing anything like a Crane 14 or larger is a guarantee that you'll run rich at idle due to the overlap. An SAFC or MS are the usual cures for that.
