320 hp TL-S????
My buddy bought a TL-S recently, and put Comptech headers and exhaust on it with no other mods. He claims to have 320 hp and run the 1/4 mile in 13.75 secs. Is this complete bulls*&t?

yeah, but thats weird, he is calculating everything at the Crank...type s is 260 at the crank, headers are like 27hp at the wheel, and exhust is like 5hp at the wheel
he either is giving it to you at the crank, or he is smoking some good shit...
am i right or wrong?..i usually dont take part in "tech" talk.

Over 300hp @ the crank can be easily obtained by 320 is very high. Also I don't think anybody on the TL board has gone under 14 without the use of boost. The only available performence mods are I/H/E and that won't get you below 14.

That sounds about right.. with Comptech headers and exhaust the guy should be running a little over 290 at the crank....</STRONG>

But about the 1/4mile time..................I smell something funny. Could it be bullshit that I smell?? Or is it NOS?

Man, post like this just go to show that many of the people on this board are either new, or just don't comprehend what they are reading. I think the max power anyone has got here from headers and intake is like 234hp which is right around 300 at the crank. And we all know that the exhaust produces essentially no power. Now, if he's claiming 320hp where are the other 20+ horsepower coming from, Magic?
Hell, I raced I Saleen mustang the other night that only ran a 13.88.
Shit, I gotta get into work and listen to this crap.

The figure of 310-320 at the crank is probably correct when you calculate in the loss you see at the wheels. The sub 14 - must be a really cold day with a perfect reaction time and launch!

OK. let's calculate:
Approximate numbers at crank:
260hp stock
33.6 peak hp from headers (28hp +20% lost)
Graciously say 6hp for exhaust
That still adds up to 299.6 in my book.
I don't care if it's -20 celcius out, there is no way a TLS with headers and exhaust ONLY will run in the 13's!!!!!!
Hell, I have headers and intake with sticky tires and I only ran 14.7 on a pretty decent night. Had all conditions been correct I would hope to be around a 14.55. Sub 14's with an auto TLS--Come on.

Yeah, there's just no way. I very rarely call BS on anyone because of the numerous factors involved in drag racing, but this one just simply isn't possible.

Fly the flag high. The key is "with no further mods.." First, you will need wider tires and new ratios in the box to even come close to the 1/4 mile time. There just isn't enough contact between the tires and the road to produce the traction.
Besides, the -s TL already uses a redesigned header (among other mods) to achieve the peaky 260 HP. I know there are better headers available, but this will not improve the power where it is needed, in the low end. Only a valve redesign and/or a supercharger and/or NOx will get this. Also, the 2-3 upshift in the TL will prevent it from hitting that sub 14; from redline in second, third drops in well below the horsepower curve of an already peaky engine.

You guys are all whacked up when it comes to calculating hp and predicted hp losses and whatever.. MikeB at Comptech claims 4hp for the Exhaust and that means 4 MAX Hp (at the crank) for the exhaust and who has actually dynoed and gotten 4 hp or more from the Comptech exhaust.. no one.. prove it.. and Comptech headers only give 24 additional hp at max hp figure in a 20% loss and that is 30.. let's round up to 32 and say 25% loss.. what is 32 + 4?? that is 36hp .. 36+ 260hp = 296 hp.. http://www.comptechusa.com/cgi-bin/f...rum=4&topic=26

I would say since it's 260 at the crank...headers 27 at wheels (so, figure about 33hp at the crank), intake 8~10hp @ the wheels (figure 10~12 at the crank) and exhaust...maybe 3~5 at the wheel (figure 4~7 at the crank). 49 extra horses at the crank..that's 309...maybe some pulleys...crank hp maybe 3~5...and advertised plug power 3~4...but 327 is really far out there. The time is really off though...13.7!?! You need to ask him how he go thtis figure...maybe on a G-Tech...

Actually the only way he can achieve 320hp at the crank without nitrous, sc or turbo would be the 3.5L upgrade with headers and CAI.. exhaust, pulleys and densos probably add a possible 10 more

yeah...but expect apporxiamately 20% drivetrain loss...remember most of the numbers we get are at the wheel.

Why are people calculating the HP with an intake? He said headers and exhaust, and that's it. Like Eric said, the exhaust are only 4hp at the crank (and that's high, I assume 1-2hp), and the headers are around 30hp (crank).... it's just not possible. He's barely at 300hp.....
