Good runs!

Willing to bet if he was a manual he would have pulled on you. They are quick

Im sure it wouldve, its a very very fast car. If i knew the guy well enough i wouldve asked him to drop it to 3rd so we can both go in the same gear. I think i need a cam, lol.

That would not be fair since he is an auto and you are a manual, not to count different gear ratios altogether.

I'd like to see that race again if you could hook on the shifts, the a6's are def fast they are geared very aggressively more so than the manuals with out 3.73's so I think it still would have been about the same result with the m6 either way we will never know unless you run into another one lol. I could have sworn there was a race on here between a stock m6 t/ and an auto 5.0 and it was a fender race? even tho good run

Possibly could be...on the street anything can happen.

5.0 could have had even more downshift issues, different traction obstacles for each car, and not everyone runs premium in the 5.0 which Ford claims reduces power by about 10hp.

As opposed to the track, where everything happens exactly the same way... every time.

No one makes mistakes at the track.

No, but in the majority of cases a prepped track is going to make a huge difference. A timing tree is also more fair for both parties than honks or an arm drop.

I understand your point but don't take it so literal.

they did a few runs and it was the same result every time it was a setup race but you are right anything can happen when racing. where did you see though that running the 5.0 on regular decreases hp? fords recommendation is only 87 octane and the motor is timed accordingly its one of the reasons the motor gains so much from a tune and timing bump.

NOPE: WAS AS FAIR AS COULD BE POSSIBLE. SEE BELOW. I FILLED THE 5.0 UP WITH 91 OCTANE FROM A VERY BUSY TEXACO. 5.0 WAS A RENTAL DRIVEN BY A GM DIEHARD WHO A COMPETENT DRIVER. Dig race always favored the 5.0, but most rolls gave a slight edge to the WS6. Races happened in the high desert, middle of summer, you dont even want to know the DA...

"When the 5.0-liter engine is run on regular fuel, it can produce up to 402 horsepower at 6,500 revolutions per minute and 377 foot-pounds of torque at 4,250 rpm. When premium fuel is used, the engine can produce up to 412 horsepower at 6,500 rpm and 390 foot-pounds of torque at 4,250 rpm. The compression ratio is 11.0-to-1."

Been posted in several other places and supposedly is even in the owner's manual.

the 5.0 lost. it will lose a lot if stock. the pcm doe smuch more than torque limit. it measures HP and closes the throttle to keep it at max calculated power. they are a joke stock untuned. not taking a single thing away from a good kill. they still make M6 365rwhp and the automatics 355rwhp.


GK OP. good runs. you have a good running car.


this is plenty well documented that a bolt on ls1 should kill a stock coyote. should.

Now the GM guys are making the excuses. What if What if What if...

Nice kill OP! Not bad for an ole fart LS1 with just some bolt-ons.

why not start in 2nd at 50? you will be in your peak power and as long as you can shift, you should have pulled a little better instead of starting 3rd not quite in your power band

Says he has 4.10s, and while I only have 3.73s, I'm at like 4500-5000 (can't remember) at 50mph, so 4.10s depending on his tire size could be 5500 or so, and that's not where I'd start a race.

Wonder if anyone has recorded a full drag strip run on the dyno. IE, what power it makes in each gear and how late it comes on after and just before each shift. When I drove the rental 5.0 in the vid I posted above, it was blatantly obvious Ford was taking power out everywhere.

As for a bolton LS1 taking out a stock 5.0, you're right: "Should" kill it. Just like a bolton LS1 Fbody "Should" run high 12's @108-110mph. "Should".

yes its recorded. there were early dynos of non tune cai and the dyno curve had a blatant drop and then recovery. datalogging is important with any change is coyote's it can and WILL cut the throttle on tuned cars if parts are added and the tune isnt ready for them. i datalog position on my runs, and wideband O2 also. tailpipr O2's are unreliable.


ill post a datalog some time.


this dyno sheet shows what happens to power when the pcm pull throttle.



a tuner who doesnt know what he's doing will tune the car and not make a single extra hp.
