1/4 Mile times for N/A Owners?

[RIPDOTCOM]

I went to the track last friday and ran a 15.9 with my timing at around 5' (now its at 16' so i should do better)

According to this HP calculator I am making 190.15 Hp at the wheels. I based it on the 3500Lb weight of the car and my added 200Lbs=3700Lbs Looks like I need another 28Hp to break into the 14's

post your 1/4 mile times and estimated HP

At least you have the guts to take yours to the track, i know i havent gone, but if i go im going to practice on my 60'foot and reaction time. Do you have a time slip you can post?

dude.............please re-edit that post and dont ever mention using a program to tell you how much hp your putting down or to determine your 1/4 mile. that shit doesnt work, there is TO MANY variables to get a somewhat even close reading.

He did go to the track He went last friday and ran a 15.9...


Peace

Thats right, my 60' times need a lot of work and I ony got 1 run in so I know I can improve it by at least .4 and run a 15.5 due to my 60' times being 2.6 seconds (im certain I can get it down to 2.2) anyway, the program seems spot on and 190hp seems like it would be a good estimate. But to make sure its clear I did track it last friday and did run a 15.9 so according to the calculator i posted I have 190HP. I dont see where there is any debate as 190hp seems very reasonable.

Well actually it will show how much average hp he needs to cover that distance in that time with that much weight. That is what hp is anyway, a work being done measurement. Yes, there are many variables. But it is what the average needs to be.

Stock GE with a W58 weighs more like 3450, and that does matter. TEMS, ABS, sport roof, and other mickey mouse shit will slow you down.

Those various programs all say the same thing. At least the ones I have seen that are correct. They say it is an estimation, or average HP needed. What the program actually does is work backwards. It is what you need to average.

Dean Marcum ran a 13.8 or something with a 7MGE. Ask him what all he did on his board.

im going to have to paritaily disagree with you. i dont think its anywhere near average and ill give you an example: i have a 03 hyundai tiburon gt 6speed, which weighs 3100lbs (3080 to be exact, had it weighed), plus me=170=3270lbs, i have traped anywhere between 92-94mph when i was bone stock, also i have had my car on a mustange dyno and on dyno packs. with Intake and exhaust on the mustang dyno, it read that i was at 150whp, when i had full bolt ons and some other stuff the dyno packs read 193whp.......now according to this website, when i was bone stock i should have been at around 205hp, now im not to sure if its reading whp or engine hp, but either way its reading really high, because a stock tib. has 171 crank hp. one HUGE variable im not sure if your considering is gearing, unless your using a calculator that has you input your gearing ratios, your not really going to get anywhere near actually readings.

 

[Nick M]

You didnt post anything to contradict me though, except you dont think it is anywhere near average. That takes into account for gearing. Because it requires a certain amount of work to push the car. You left out too much info to check. You said you went 92-94 stock. With what ET? And what is your ET and MPH with your mods?

edit:
I made up an ET of 15.5, and you used 170 hp at your weight. Of coruse on a dyno, hp is not constant. That is why this is an average.

you told me the calculator reads average, im telling you it doesnt, i also supported my claims. stock my et was 15.2 and moded my et was 14.5 at 95, couldv gone faster but i was on street tires and stock clutch.
also what gearing does that calculator take into account? for all you know it can be for a mini cooper. like i said earlier, the calculator said i should be over 205 stock when i was actually only at 150. now i have proven my findings please prove yours. if you would like i can get some time slips and dyno charts for you.

just so you dont take it the wrong way, im not here to start a fight, but if you want to argue this with me, im more than willing to have a friendly argument.

 

[Nick M]

Nothing taken the wrong way. You must realize that the formula is converting energy spent into numbers expressed as work done.

You don't input gearing. As gearing does not change the HP.

It is the exact same formula as the dyno uses, just in different form. Well, not the Mustang dyno, it is a loaded dyno, where as a dynojet is an acceleration run.

You do know hp is calculated not measured.

Anyway, using a stock GE like his they turn mid to high 15 at 88-90. Not every car every time, but averages. At 3650 estimated weight with driver, a 15.8 @ 88 requires 198 hp of work to be done. Average. As the car isnt making 200 hp at idle, but not until redline. It is just an average of work needed. His 15.9 isnt 191 rwhp. If that is what that particular site claims, that is wrong. I don't know, havent looked at it yet. But there are many sites that use two formulas for calculating work done.

14.5 in a Tib is scooting pretty good.

I am stock and have not been to the track but today I ran from 0 to 60 in just under 7 seconds. no mods. I used to have a nissan xev6 x cab it weighed 1700lbs at 170 hp. 0 to 60 in 16 seconds and I thought the truck was fast till I pulled up to a supra.
