Despite my crappy compression #'s, I hit up one of those "horsepower calulators" online.

According to Billy's G-Tech, I run the 1/4 in 15.1 at 96 mph. The car and I weigh somewhere around 2600 lbs. Punching those into this calculator:

net the following:

Trap Speed Method: approx. 180 HP
ET Method: approx. 149 HP

Averaging gives ~165 to the wheels.

Interestingly, this site:

show's that The Fedsmobile would line up pretty good against a stock S5 TII.

When do y'all wanna hit Cayuga?

 

really, i wouldnt doubt it. Full exaust plus some intake porting, and those mad-quick brackets yo.

 

Thats a neat calculator


I would believe those numbers.......Cayuga eh? where the hell is that?LOL

We should have a 1/4 mile night sometime for the Hammer/Pennisula guys........an me......sometime maybe mid-july? Thats when we'll have the most people to watch us brap brap brap our way down the track...

edit: I'll run er hard too - if it pops I can push it home or walk, whateva...

 

My S4 N/A motor dyno'ed 117whp and 114 ft/lbs for tourque.....I was kinda sad But it was a tired old worn out motor anyways.

 

I am going to have to raise the BS flag on this .... =P

Lets have another dyno meet so IAN can SHINE again!

 

Jamie, I think the calculator is great. Just plugged mine in and it calculated 188 rwhp. What a fantastic tool! I love it.

Anyone want to buy a 188 RWHP stock port 6 port????
Only $2,000 Cdn. J/K.

LOL, engineers will believe anything if it has calculations behind it. Sales guys are the easiest marks...

Actually, I think it is a good tool that can be used to establish the effects of power improvements. Just like chassis dyno's, a good indicator but shouldn't be taken as gospel.

I think Eric is calling your BS too
damn enginears!!

 

No, not exactly B.S. I believe that a lot of the simulation tools are valuable as an indicative tool and there needs to be some level of real life testing done to determine the effectiveness of the calculated model. I have spent a ton of time with the Bosch LapSim model and found a very strong corelation to real life and use it a ton as a car change effect anticipator.

In Jamie's case he has in-car test data used as a data model. He adds a number of correction factors supplied in this model and "voila" a H.P. number is pumped out. As Jamie is an engineer, he believes in the sanctity of calculations and hard numbers. Me, an old real life kind of guy I tend to believe in dyno's, lap times and data loggers. Interestingly though I tend to agree with the e.t. claimed H.P. as a realistic RWHP for a stock port 6 port with a header, flowed throttle body and intake.

Now, however if Kristen had made these statements..........

 

See I go the other way. I'd buy the MPH # more, since ET is very dependant on launch, and I only did 2 runs. No optimim launch. However, getting to a certain speed reflects a change in energy, and a change in energy in a certain time is the definition of POWAH!

It would be straight up simple to calculate HP from a trace of the rpm wrt. time, knowing weight and gear ratios.

That said, at the end of the day, first one over the line wins.

 

I would say the trap would be more accurate also as the et is highly effected by the launch which is effected by tires, suspension and driver skill. The thing that I doubt most is the g-tech, they are notorious for giving slightly faster ets and way faster traps. Notice how there is such a drastic difference in the hp on the trap and et, any car that is trapping at 15.1 would have a much slower trap than 96. I'd estimate that a g-tech 15.1@96 is a real 15.4@89, if you went to the track and got those numbers then the calculations would give you a good estimate of hp.

 

Yeah, Gtech does not average trap speed over the last 30(?) ft. like a real drag strip. Plus, time is from first move, not from the re-connection of the lightbeam, so I would imagine the ET is a little too high, and the time is a little too slow.

If my clutch holds together, I have no doubts about a 14.8
