I'm not saying the op is right or wrong but an untuned h/c ls1 would also probably have a hard time beating a bolt on ls1. without a tune the powerband and overall power will be down the *******. now that your tune you should be trapping 4-5 mph more than a stock 392 and should give him a pretty goo beatdown

my mustang ran a 8.0@86 with a 1.73 short time. Its not totally unbelievable.

Thanks for the input guys 100%sure it was a 392 the challenger was green with black stripes with red 392 badges behind front tires. Dont get me wrong i didnt stop a mud hole in this guy each time i shifted he gained so ground but once i could strectch 5th gear thats when i pulled ahead the most. Closest race i have been in yet. Could have been driver error in his part when i got home and looked up the 392 stats i was just as supprised as each of you. I guess dont under estimate the old ls1.

OP if you were driving an N/A Mach 1 this would be more believable.

I really don't know why this is so hard to believe . I have never races a 392 but many srt8 and rt challengers. I pulled on these cars pretty good with bolt ons only . And btw.. My bolt on ls1 runs 7.78 in the 1/8 .

its not hard to believe but just an fyi for ya.. the new 392 will do mid-low 12's stock at 114 whereas an old srt8 was a good race with a stock fbody.. clearly thats not the case with a new one

Can't argue with that. It was night and day after the tune. Still want to go to the track and see what I do.

Friend of mine has one<new 50K SRT8 Challenger and its Envy green too> and it pulls very hard from a roll ==BONE STOCK. It will pull hard all the way to 173 mph too. The LS1 will not unless it is highly modded. From a roll I have to spray it to beat him. From a dig I can walk pretty good off the line with street tires and kill him with sticky tires out of the hole but he is coming hard once he hooks it up. Once he puts some sticky tires on it I may be in trouble==but 20" DRs are expensive. I have bolt-ons 02 SS. I guess my car is slow.
4120lbs with 470HP/470TQ will move out.

What rear tires were you running with those times?? V8EATR and f00rmy??

The feed back here is very intresting seems to be all over the place. Its seems a bolt on ls1 makes 360 to the ground thats around 400 at the flywheel give or take. With weight reduction the ls1 is what 3300. Thats 850lbs differance and the 392 makes 70 more horsepower. Seems like its a drivers race to me. Could be wrong.

The confusion is that you ran from a roll. The 850lbs doesnt matter near as much from a 60-140 roll as it would from a dig. The weight is already moving pretty good @ 60mph. From a Dig it is a lot of weight to get rolling=True? My car did not make 360 @ the wheels with bolt-ons with a 4l60e with a convertor....more like 340. I just dynoed it again last saturday night and it was weaker than that ==kind of pissed me off but I think the dyno was off a little based on what others said that dynoed their cars also. Not ******* your kill just based on my experience with the new SRT8 challengers,, driving and racing it because I know somebody who owns one and his brother owns the 2010 6.1 liter that is alot slower than the 6.4,, 392. Another thing is that car has 470tq==That is a ton of torque and runs a 3.07 gear. It flies to 170mph like nothing then is computer governed to shut it off.
Your car runs very good for what it is.

01ls1v8

I have heard that most auto cars with a converter dyno a little low comepared to the stick cars but the auto's are faster on the track. Who knows with my 4:10s 5th is good for about 155mph if we kept going he could have bet me. My slows down a good bit when i hit 6th gear havent made past 165mph keep catching traffic or a turn on the interstate.

LT/LS Guy

Auto's are *usually* quicker down the 1/4 but not faster. But I know what what you mean. Question #1: What does your car weigh? You said it has weight weight reduction, just curious how much. Question #2: Why are you running up to those speeds on the highway where there is traffic? That's stupid. You're going to kill yourself or someone else.

01ls1v8

Thats what my wife said. Weight reduction is no front bumper support no cruise control modual no back seats no cat back or cats no air pump no carpet insulation no spare no cd changer no fog lights no cat back heat shields no rear speakers no rear bumper support no mats. I think thats it.

LT/LS Guy

That's a pretty decent amount. Not suprised you pulled a stock 392 by a car. Not all of these cars are trapping what mine trapped. I have seen a few in the 112 range stock. Again, G/K!

86mph in the eighth is generally 107mph in the 1/4

a 392 Chally typically traps 112mph.

maybe the chally he raced was a manual and dude couldnt drive. a 5mph difference is pretty noticeable.

My 86 in the 1/8th was a 110 trap, when I trapped 85 I was hitting 108-109 (that was stock and stock/lid)

Also confirming my car without a tune is a hot mess... A tuned bolt on car would own me right now.

Fwiw the manual 392s seem to be way behind.. A 112 trap would be generous IMHO.

Good kill, those Challengers (obviously not champs) are junk.
