Easy to explain
They run at E town and the track is prepped like you wouldn't believe. Add a small guy driving and its believable in good air out here

YA it seems low but I ran a 11.88@106. But I had a issue with tranny and couldn't get into 5th. Issue fixed now.

To me, I always looked at trap speed as a good indicator of power..more so than ETs. ETs can be manipulated by such things as gearing, tires and as mentiones above, track prep.
With this in mind, the 427R is a 108mph trap car but pushing that much Hp?
Sounds like to me that the Hp numbers are a little over-inflated or the car is extremely heavy. I don't know what it is but something does not add up.

Numbers are overinflated. Probably a 380 crank hp car.

I agree there. Anyone know what they dyno stock?

IMHO Mustangs didn't become impressive until 2011, I say it took them enough *** beatings in family sedans like this vs. a "430hp" 'stock sports car' over the years to finally get it right with the 5.0.

Besides the Termi, Mach 1 and GT500's I have to agree. I also went to the 5.0 from a G8 that made 489whp/522wtq with some spray and 370whp with no spray. I busted a lot of mustangs ***. Surprised the shot out of them. Would still have the G8 but few people decided I didn't need it by crashing into it.

Yet I think one reason Ford was not big on pushing the mustang is cause they had no other car to compare it to. The camaro and TA was no more so no reason to throw gobs of horsepower in it.

The first 5.0s were kicking *** back in the day. The Cobra Rs were nothing to sneeze at and the 93 Cobra was nice for its time. Past Boss's were nice too and what about a late model Mach 1??? Some of your GM guys are BLIND. You don't have to like them and or want to own them but geez....

Based on those dyno runs the cars should trap higher in my opinion. Maybe one of the Roush upgrades includes filling the trunk with rocks

I know the videos are bad but you have to consider

A. It was dark outside
B. It was recorded on a phone
C. It was completely spontaneous

Yeah, that's all wrong. That is almost like a Tesla, light weight, no top-end.

And then only a .1 better with DRs? So somehow that decently heavy car was cutting 1.7x 60fts or better on street tires? Doubtful. iirc, on street tires, high 12s @ 110-111mph.

A friend of mine hit a 1.7x on street tires (auto car) one night at the track. It was a one in a million shot though, with great prep that night, not something that happened consistently.

I think the car went 12.2 @ 111 or 112 mph that pass.

the Cobra-Rs were fast. wanna say C&D or one of the mags took one stock mid 12's at like 114mph but i mean they were pure racing cars. no AC ect.

ive seen quite a few of the 427's run low 13's around 107ish mph.

if you see one running 12.4@whatever. then every other car there will be running about 5-6 tenths quicker also.. just sayin lol

Sounds right with a 1.7x and that mph, assuming a full-weight car. Was it a Mustang with a blower?

Low 13s @ 107mph I bet were 2.1x 60fts...
