04 Srt-4 with stage 2/ no toys. how impressive?
ORIGINAL: PSI Chick
forget the crank crap. all numbers that srt gives are wheel hp numbers, even the stock numbers.
s2 (or s3 for that matter) is not for dyno queens. if you want a high hp number go another route. it's for people who want to see performance at the track.

Stg 2 with an exhaust adds about 30 hp. Give or take. The drag math I used was from another website and I dont remember if it was for crank or wheel hp. I'd lean towards crank. That is usually what those calculators show. However, they are very flawed when used to calculate fwd with traction being the issue that it is. So that is a ballpark figure at best. When if ever I get use my buddies slicks, I will have different #'s to use and I'm sure it will show a higher hp even though there will be no engine changes. Mopars own website shows stage 2 with toys to be good for 278 hp and 300 ftlbs if I remember correctly, and I believe that is at the wheel. I will post that link when I find it. I dynoed my car before the stg 2 at 242 hp at the wheel with 260 ftlbs of torque stock. So as you can see theres a lot of fudging going on. If I was to guess what my car would dyno at right now on that same dyno, I'd say right around 280~290 WHP/ 300 ftlbs.
Here's the link. Go to the turbo upgrade interactive demo at the center bottom; http://www.mopar.com/performance/index.html
Also, here's a hp calculator that is not the same one I used, but it works the same. Actually it gives 2 numbers; http://hpcalc.boostcontroller.com/
Now plug in my race weight of 3140, my e.t. of 13.6, and my trap of 107 and it will show you 300 hp by trap and 247 hp by e.t., or, use your own numbers.
Remember that e.t is less accurate than trap because of the lack of traction. Basically, what you can read from this is, I have about 300 hp, but I can only put 247 of it to the ground. LOL
Or, look at it this way; out on the highway from a roll, my car performs like it has 300 hp. From a dead stop, for the first 1/4 mile, it performs like it has 247 hp. 53 hp lost due to traction! Yeah FWD!

yea really what's with all the online calculator stuff. you have a 13.6@107 car. end of story. if you want to know how much power its making go to a dyno. a real one. online calculators aren't worth a thing. according to one i found i have over 800 hp and do 0-60 3s lol. yea ok.
Haha... well look a dino would be the best route obviously. I kinda get an idea from my c=scan gauge on how fast the car is. I was in 4th gear and only at like 4500 rpm's and the numbers said 265hp. Now I don't know how accurate that is...
I have s2 w/o toys on my car with
DTEC
3" TBE
Intake
TB
so just to give an idea. My car is on it's way to the states now so when I get to maryland and get my car, I'll be heading to a dyno.

Here's the deal with a calculator, like any math equation the info you get out is only as good as the info you put in. At best, it is going to be a ball park and just enough ammo for a discussion such as this one we are having now. Calculators should never be regarded as the bible numbers for your car. I would think that would be obvious. They are usually based on tested formulas. You just have to be honest with your numbers, and understand how to read the result. In other words, how much creedance you give to the answer. The calculator I posted, for example, using PSI Chicks sig numbers and assuming a race weight of close to the same as my car, gave me the answer that her car made 434 hp by the trap speed, and 408 by the E.T. and according to her sig, those numbers are pretty damn close. Knowing that turbo cars do not always dyno as well as they run at the track, I would say those numbers are very very close.
As I posted above, I have dynoed my car, but before the stage 2. I would like to dyno it again, but I have not been able to get up to where that dyno is. However, I have raced and I do have those numbers, so a calculator gives me a clue to what my mods have done for me. For another example and just to drive the point home, if I punch in my numbers from the previous year at the same track, (13.8 @ 99), I get that my car was making 238 hp by trap and 236 hp by e.t. and that was very close to the same time I dynoed the car and the exact same state of tune. As I showed above, It dynoed at 242 at that time. So, it would seem this calculator is pretty damn close.
People afraid of math FTL, People afraid of racing FTL, People who believe only one dyno in the whole world is the accurate one FTL, People who dont like to speculate, bench race, real race, experiment, test, post thier numbers, give help to fellow SRT owners, live life by doing FTL.
People who are smart, helpful and open minded FTW.

um...i would say people who don't want to speculate and bench race ftw. get your *** out there and run it, don't assume.
oh and just to add to your list one thing that drives me nuts.....ricer math ftl!!!!!!!!!!!!!!!!!

Ricer Math!?! You are showing your inexperience/youngness now. These calculators have been around for decades before the term "rice" was even coined. I have a Direct Connection catalog from the late 70's early 80's that has a couple of pages of "ricer math". Let me explain to you youngins, that back a few years ago, ok, decades ago, before there were computers in every home and dynos on every corner, you had only your qtr mile time and the weight of your car to use to compute your hp. It was always "estimated" this way. In fact, the NHRA knew this and when they saw factory cars with whatever advertised hp run impossible qtr mile times, those cars were subjucted to "ricer math" and duly re-classified.
I fail to see what is wrong with taking your qtr mile time and your race weight and computing a horsepower.
In fact, all a dyno does is compute horsepower. The dyno itself, can read only torque and rate of velocity change. It then does "ricer math" to give you a horsepower. You are doing basically the same when you calculate your own.
You guys are just silly.
Heads in the sand FTL!
BTW, you cant do the math, if you dont have a qtr time. So I do obviously run mine.

I'm going to overlook the majority of your post and just say this ...... maybe because we are not "old" and didn't grow up having to estimate, we are reluctant to use anything other than technology that we were taught to use. HP is just a tool used to measure ***** length......
