the dyno #'s are in for the ls1

[sleeperstyle]

275 rwhp on motor. THAT'S IT! ask anybody at rev-it-up and they'll back me up, it dyno'd less than a stock ls1 does. the 150hp shot gave me almost exactly 150hp, so do the math:wink:

so who wants to race?

why don't the people who dyno'd 300-350++ hp and raced me post up. i want to refresh my memory about what happened. i can think of quite a few but i'll let them tell the story.

-nick, who thinks dyno #'s don't mean dick and et/mph tell the story.

revitup=:supz: :rock: awesome guys, cool as hell. i wouldn't hesitate going there again to tune in the a/f ratio in the future. alot of goddam neons though.

[EvlEgl]

yeah theres a lambo parked in my garage to...

[wgknestrick]

auto????????????

[TROLL]

yup its an auto and i dont know if its my place to post his timeslips but its a very quick car.
what kind of dyno do they have?

[TalonTsi97]

auto????????????
Nick its all good, track numbers tell all and thats what counts in the end.

Did ya get the new intake manifold yet?

[wgknestrick]

auto totally explains the low dyno HP#s. Don't think that is all the engine is making. dyno-ing auto cars = almost worthless.

I am surprised it made that much. Post the graphs

What i wanna know is how you dyno lower than stock...

I've seen auto LS1's make Power.

two I know of have over 400 to the wheels.

10 bolt or 12 bolt rear and what gears?

[Silverfc88]

What was the torque?

It all depends if they can lock them in gear or not. You won't get close to an accurate run with it shifting @ 4K RPM everytime

[EvlEgl]

If an automatic is worthless why do all the 8 second supra guys have powerglides?

[wgknestrick]

You miss-read my post. autos= "worthless to dyno" unless you can lock them in 3rd or 4th gear

[EvlEgl]

so your telling me it's a stock ls1 with a 150 shot

[G1GSX]

nicks motor is stock pretty much

[wgknestrick]

so your telling me it's a stock ls1 with a 150 shot

No, but go watch about 5 automatics dyno and you'll know what I mean. I think he is comparing it to what a stock MT LS1 makes. An auto can pull for about 2s on the dyno before shifting into the next gear, they never get close to redline and most dynojets don't load the car enough compared to real-world which causes problems with some TCs. All this leads to much lower maximum #s on dyno pulls, but doesn't mean the car has the power.

Any turbo guy will attest to having to tune their electronic boost controller just for the dyno because it does put enough resistance on the wheels to fully load the engine to make the same boost. Mustang dynos are the exception and this is why the generally read lower HP. I always have to set my EBC to target about 5psi higher than normal on dynojets to get the same boost as what I get on the street.

From what I've seen, you can add up to about 50-100hp on top of what an auto dynos at to get the "true" whp depending on setup.

[EvlEgl]

Soultion...Get a stall.

[D Money]

Those dyno #'s don't mean ****. His car is consitant at 12.1 without juice, 11.1 on it. I have seen Nick smoke cam'd evo's with 355whp without a problem, he also ran close to an fp green powered sti with a tuner who drives it, off the juice obviously but on the juice it was no competition. Reguardless it takes alot to beat him, but I wouldn't say he is unbeatable...

[EvlEgl]

your always faster than someone, but someone is always faster than you

[peteyturbo]

The 275 RWHP seems low, but it's just for comparative purposes, RIGHT?? :)
I mean its a 3800lb car doing 110 traps right??

about 3650 or so :cool:

the car has a stall- unlocked #'s. stock AUTO ls1's usually dyno more than my car did. it was locked (via hptuners that i use to adjust the shift tables) in 3rd gear for the pulls.

i didn't even get copies of the graphs, didn't care:lol:. sorry.

it is a dynojet, so it actually may have read HIGH

definetly just for compartive purposes- and maybe to get a couple races with cars that have more power than me:banana:

[peteyturbo]

My animal of a car put down 298 WHP on a mustang dyno at PDT lol. Later I come to find out they were getting sparatic readings that day because of a faulty power supply and they offered me a free chance to come back and do it again.. I just don't want to deal with trying to get talked into buying something.. I guess that means I am making more power then you, let's race!! I'm seriously thinking of Atco today..about 3650 or so :cool:

i won't be back at atco for a couple weeks. need to do some simple routine maintenance and put my driveshaft loop in first.

you already smoked me anyway:finga:

nicks car is a monster... Any reason that you would have dynoed lower then stock ls1's? other then the auto

12.1 on motor...maybe. NOS is sweet! The STi he ran is a 12.0-12.1 second car.
An auto def dynos ALOT lower (10-30%) than a MT. Alot more drive tran loss, and if you add a high stall TC, it will be ALITTe worse.

[C'DALERIDER]

NO, unless the engine is "dying"/loosing compression.

[dolphinS4]

A car running 12.1 better have more than 275 whp.

I think its safe to say we are looking at the results from running in the wrong gear. I would guess the reading was from a redline run with a gear lower than 1:1.

Just a guess though. Eithier way, running a 12.1 is impressive to me.

[SinistiR]

My car(the STi) is putting down 392whp on pump gas, weighs 3500lbs and traps 117-8 on pump gas with a best 60ft this year of 1.89.

[347gtvert]

sleeper - do you shift out of 2nd gear by the end of the quarter w/ those 2.73's?

[C'DALERIDER]

you can go over to Xotic and compair dyno pulls with RIU???? They have a dynojet also. It be interesting to see if there is a difference. Thats pretty low. Sure you were not sandbagging the pull?

[brk4sti]

Why should a car that runs that make more power guess what it isn't a civic its set up to drag race plenty of guys run 11's with 300hp it just proves what me and nick say dyno numbers mean jack

my srt lost about 150whp when i put the auto in and still went 11.6

it's all about tq multiplication

[sleeperstyle]

12.1 on motor...maybe.

wanna put your $ on it? i've ran that multiple times, but also ran a ton of 12.20's and 12.30's- althought it is usually pretty solid low 12.20's to 12.10's.

dyno'd in 3rd gear, 1:1 ratio.

347gtvert- i get about 20mph into 3rd gear in the 1/4 mile on a motor run- a good bit.

[sleeperstyle]

you can go over to Xotic and compair dyno pulls with RIU????

because i like revitup (nothing wrong with xotic im sure...) and i don't care about comparing. i think it is funny it dyno'd that low.

[Tiny]

Actually, looking at your MPH and the weight of the car it's not that far off. You make up for the HP in the short track, and I went 12.2 on radials the day I raced you and we were pretty well matched on the street, so I believe it without question.

i understand what you are saying and agree- but short track?:lol: in my book that is the 1/8 mile.. (?)

stock ls1's DO dyno closer to 300 too:banana: , i read 1000 sigs on ls1tech with nice high dyno #'s and minimal modifications. guess mine is just a turd:mrgreen:

[TurboTagTeam]

Set-up is everything. People just don't understand. I bet if you ran wrinkle wall's you'd hit 10's easy.

[ITSTOCK]

Was it not already pointed out that you have a decent size stall?????? Stall convertors+dyno=inconsistant+(usually) low.

Let the track times speak for themselves! Your car runs!!!! Just out of curiosity, what was the tourque? Also, what's the STR on that convertor?

[sleeperstyle]

torque? what's that?:wink:

[TROLL]

ha... ha... ha... busted! come on, out with the torque numbers i say!

[C'DALERIDER]

Set-up is everything. People just don't understand. I bet if you ran wrinkle wall's you'd hit 10's easy.

oh, we people understand that plenty. In the suby comunity, the PR's are running mid to low 10's with relatively low mods. Why? they practice driving all the time and they know how to set a subaru up correctly for the track running on.



When people really undestand what area under the curve means and how to make combinations that create that power band everybody would see a lot of cars running very fast numbers.
I know that alot of people here thinks that they only needs just buy a lot parts and reach good numbers on the dyno and the car are ready to run 10sec.
Just a small hint to every single Subaru owner that wants to run 10sec. Work on the suspension and on the clutch area. Then you know the rest
Maybe you guys know about a few cars with more peak horsepower but to run fast times you need huge power to the ground on every gear not only on 4th and 5th gear.
Thats the reason you see cars runing very high mph but not so fast times.

at least my tires fit.

no graph- but i have timeslips.

oh, where is the person who called bs. on me mentioning a ls1 that dyno'd ~330rwhp was running 11.40's? im wondering where they are now...

i figure with my 275, and ~ 3600lb car if i can go 12.0/12.1, they why can't a stripped 3200lb car (minus 4 tenths from me) with 50 more rwhp (minus another 5 tenths) go mid/low 11's? i dont' even have the right gear setup also.

[TNTramair]

my oh my what a **** storm your starting in here..lol.

you know if you take the converter out of the equation you'd be right where your supposed to be...310-330 with your mods.

[sleeperstyle]

it's stock is absolutly right. from a scientific standpoint it is physically impossible with my hp/tq #'s and the weight of my car to run those #'s.

i wanted to go again this thurs. to try and do better (im CONFIDENT i can squeeze some more out of it with good air and if the drivetrain holds up) but rain for the next week starting thurs. hoping for at least lower 10.90's, but shooting for a 10.8X in 0 or negative da'. my car went 12.30 on motor that day so i know the air was far from perfect, plus i can delete some weight (30-50lbs easy).

Well wait, he said he didn't believe you ran it, not based on your numbers. I still don't know what exactly you put down and what weight you were running, but I don't think you lied about what you ran....correct?

Found this today in June's Road and Track page 160:
These are formulas they use to estimate hp and ET times:

BHP= (mph*234)^3 * weight
or
BHP=weight/(et*5.825)^3
Using a weight of 3650, et of 12.2 and trap of 110 you get 379 with the first and 397 with the other.

cant use that formula cause it doesnt take into consideration of gearing, air density, torque converter, 60' times....all elements that effect 1/4mile times obviously.

[y3llo_GTO_burnout]

sleeperstyle stop jerking around these kids(i.e. 2point4). 99 /100 dynos aren’t calibrated to properly account for the torque multiplying effect of high stalls. Instead they’re usually set up to generate nice fat dyno queen numbers for manuals, like TNTRamair’s for example. On a dyno calibrated for an auto with the converter’s stall torque ratio parameters, etc --- sleeperstyle’s one-dimensional rowboat is probably putting out peak torque numbers in the area of low 6XX ft/lbs (on steroid juice). Add a sticky tire to ensure that force keeps moving forward and the math translates perfectly into the stated 1/4 times.

So how do you calibrate a Dyno Jet dyno for a high stall?

[y3llo_GTO_burnout]

Sinistr, shops can't be bothered. They're too busy doing other things, like bleeding customers. IMO, dynos are best used for one purpose. To establish a baseline figure for your vehicle and then when you return (preferably to the same dyno) compare any future changes to that number. They're not consistent as measuring sticks against other dynos or other cars.

2point4 so you mean to tell me you were going out solely for meeting me? Remember, I counseled you about this unhealthy obsession. You can remain president of my fanclub (as always), but I’m sorry… I must decline…. we can not date.
