FYI: weight of the car & MPH = HP /MPH is just how your getting the power to the ground!

Tims - I understand that, but your car also doesn't dyno at 390rwhp either... its rated at 390bhp, which in reality the car dynos around 370, which has that tool putting you off by 25rwhp (or so) depending on the car/weather. There have been Cobras that dyno 360 stock, but I don't think i've ever seen one dyno over 375/380...

Realistically, your car has 450rwhp +/- ... If you don't believe me; go ahead and get it dyno'ed...

Oh btw.. the fact that you say you have over 500 passes and use random things like that to base your power on only shows that while you might have track experience which is something most people lack; you really aren't that smart.

You can have two cars with exact same hp with the exact same weight run two different ET/MPH based on suspension, gearing and tires. How can that tool be somewhat accurate?

you know i had a dyno'ed 440/480 number for my 2003 Cobra and I ran a 14.2 in it one time (3.4 60" or something like that)... What would your tool show then? It shows me approx. 268rwhp...

For someone with so much track experience as you say.. you really seem to not have a clue sometimes.. you cannot use your track numbers as a dyno due to the variables in the equation at the track. I would try in Spanish and Japanese but im not bi-lingual. You have to take in effect: Altitude, launch, track conditions, etc.; you in your car that runs a 12.09 on your track, might run a 12.4 on mine, or maybe even an 11.8 on mine.. does that mean your car has gotten more rwhp? NO.

Stop posting this garbage, because there is no way that you can expect that website to be able to dyno or tell you how much power your car has within a reasonable number. If you want, take it to the street/strip section and have the guys that really do run a lot tell you also.

Who cares about dyno queens anyways? It all about the 1320 times. The only thing that you should use a dyno for, is making your car run right (tune) and that should be your only concern. Dyno numbers should not be used as a measure of manhood.

Unfortunately, for some people they are. However, I will not lie and say it wasn't cool just knowing that my car had 500+rwhp.. and im sure it'd be even more knowing I have 600 or 700, etc.

....hummmm...I was going to say sometime I should not, so I won't! How many years you been around the Mustang's??

I have 20+ years, learned to drive and get 100% out of my stuff! Enough said! ...Keep TELLING YOU...ET has nothing to do with how much HP your making! ..If you run a 14.3@120, you're not making 268 HP as YOU stated, your making 500+...You just can't get the POWER to the ground!

So who's posting garbage?? ...Mine = fact!

Tim... Your tool shows that 200 some odd rwhp.. actually to be honest, because I threw the slip away right after I got it for obvious reasons.. I really don't remember what the trap was... but before I ported my blower I ran a time close to yours 12.1xx @ 119mph with a dyno'ed 440/480 car... Now, I never had my car weighed but i am approx. 200 lbs - so do the math.

I might not have been around Mustangs as long as you have due to my age (im 24 btw). But there is nothing that you can say that gives that calculator or any like it ANY validity whatsoever. Due to altitude I have seen blown Cobras running ridiculous times (high times)... trap speed itself can vary based on gear that you finish in, 60" time, traction, weather an altitude.

Now i know the internet everything needs to be taken with a grain of salt.. but as found on: http://www.2theschultzs.com/jarod-drag.html

This particular person has their times in Denver with the corrected numbers at sea level..

13.510 @ 100.47
12.532 @ 108.24

Based on this if we use a number at 3500lbs... Again, the peak numbers will be skewed but the difference in the numbers won't be. It would maintain for any weight number you use.


3500lbs 13.510 @ 100.47

Based on the ET your tool shows a rwhp level of 281rwhp
Based on the MPH your tool shows a rwhp level of 277rwhp


3500lbs 12.532 @ 108.24

Based on the ET your tool shows a rwhp level of 351rwhp
Based on the MPH your tool shows a rwhp level of 346rwhp

Pick your next argument. I have just proved your tool inaccurate. Same car, same run, different spreads. How can argue any different?

EDIT: Your link shows calculators for both ET for RWHP and Trap Speed.. So I am using both.

Oh jeez. Forget the tool. Throw the car on the dyno already, to see what it's making.

...Dyno time coming in the spring ....I was just trying to get a rough idea and look what it turned into...

xxkazp3rxx

lol you'll see... remember this thread I say 450 or so... especially with the bigger pulley.

Understood.

As far as headers go, It will be my friend and I who will do the install, Which will save a bit of cash.

the ported blower with nitrous is the original route I had in mind.
