Guess how much hp on dynojet
We know about Evos - you don't have to test our knowledge. You can never guess power off of one timeslip - you need several samples in order to make a good guess, but as I already said, 103.xx mph is indicative of 240-250whp UNCORRECTED on a Dynojet. That is taking for granted that the dyno runs were made with the same exact conditions as the drag run (weather, altitude, mods, octane, boost, etc.).

Kaw, you're right. There have been plenty of people who have run this slow with ~300whp, but I am basing it off the trap speed alone while ASSUMING decent driving. If there are any anomalies like big changes in weather/altitude or a terrible launch with missed shifts, then there would be no reason to make guesses.
FYI, I put down 248whp stock on a Dynojet and ran 13.17@103.89. High 103 trap = high 240whp, thus my estimate for his 103.xx = 240-250whp.

dont be so uptight W, this is just for fun =)
just nothing to do at work
ok, here is the dynosheet, haha
let me know what u guys think, low, high, normal...

Are those curves with the same mods before and after tuning, or do they represent pump gas vs race gas? I ask that because the green curve shows extremely lean AFRs that appear to stay as high as 12 even near redline, which would indicate a race gas tune.
These runs were in mid-July, so they're not applicable to now. Your car should be more powerful now, but many things could have changed since then to make it slower from boost leaks to other mods to a weak clutch to a bad tank of gas. Removing the STD factor while assuming the higher number is your current power level, then you're putting down 265whp uncorrected and should be trapping 105 at least, but since the dyno was back during the heat of summer, then it's hard to say.

the 1/4 run was back in aug also, the temp is about the same as that dyno day, maybe 5-10 lower.
the 2 tune is a before & after with same mod, same 93 oct. I first though the car was lean also, but i been running the car hard in prosolo and many local and nat event without any problems for the past yr. so i am thinking if it didnt blowup yet, it wont, lol. u got to remember i am not running high boost
i dont think the number r too bad givin the fact i am running stock boost+hi-flow cat in 90+ weather
we did a test where we pull the pills out of the boost line and dyno it back to back. the car was hitting 300+ on the same dyno. but due to the fact I am running STU in autox, I cant touch the boost at all. =(
but i am not disappointed at all, I would like to have more power with the same mod, but it is what it is =)
The slip was the first time i even drag race any car, did some prosolo drag starts but thats about it. I am sure the car is good for mid 12 now in the colder weather
