ls1 dyno
 

I've been a long time reader of these forums, and I'm sorry, I now have to say something. the ls1's are more powerful than the lt1's, yes, but some of these dyno claims are ridiculous, my 99' dynoed at 276 hp and 307 torque...thats about 325 flywheel hp, and about 360 torque, underrated, yes, but I've seen some people claim to have their stock z28's dynoing at 305-320 rwhp...cmon, give it a rest, they dont make that much.

Some do.

I mean, z06 vettes only dyno at around 340-350, are you saying that your ls1 camaro/firebird has only 25-35 less horse than a z06?

my car dyno'd at 331/342 with just a catback exhaust, lid, and throttle body. I doubt that stuff would give me 55hp which is what it would be if mine and your cars dyno'd the same HP stock. Yes that was with the stock ls1 intake and no headers.

I am not saying mine does...I have no idea where my car was at stock. But the majority of M6 F-bodys dyno around 300 to 310...some higher.

If yours is an auto, then your #'s are about right. If your's is an M6 then your car might need a tune up or have something wrong. The dyno #'s you've heard about are true. They usually dyno 300+rwhp

If i recall, even hot rod magazine dyno'ed them way back in late 98', with the 6 speed, they were getting between 275-285 hp and 305-315 tq.

Every car is different some put down better numbers then others.

Also depends on which type of dyno was used.

here is my stock dyno graph. My mods were flowmaster 80 series (no better than stock exhaust) and FRA. As you can see, stock Z28, M6, made 317 hp.

add in better heads (241's), better exhaust manifolds (00-02), and better intake (ls6 01-02) and tell me that these 305-310rwhp bone stock dyno's are bullshit.

yea there is a differance in the 98s and the the later models buddy.

As with every car the first few years usually the lowest horsepower of all.Don't compare your 99 to the 02's your wrong.

If that's true, then you should know that it's very common for people to make over 300rwhp on stock LS1s.

If you have a '99 M6 LS1 making 276rwhp then you are on the very low side of stock LS1 power. In fact, I'd guess that something is robbing you of about 15-20rwhp, perhaps KR/timing issues or poor A/F ratio due to an MAF that needs cleaing, plugs/wires/fuel or air filter that needs changing, reduced cat flow, etc. Or, if the motor has a lot of miles, maybe some compression has been lost?

Hell, the stock '98s and '99s I've seen dyno make 290-300rwhp as well.

Exactly, the 01's and 02's only dynoe about 5-10 rwhp more than the other years. My 98 Z28 dynoed 298 rwhp bone stock with about 56000 miles, so you might want to do a tune up or something because that is kind of low for any year LS1.

My BONE STOCK 02 SS made 311/334 with about 3,000 miles on the odometer.

Stock with lid and filter only Dyno Graph

i have a 00 z28 with the A4, it had about 55,000 miles when i put it on the dyno, it was bone stock. the dyno was a dyno jet. i made 269 rwhp. and 296 rwtq. which i thought was pretty good for an automatic, plus the person who had it before me was pretty rough on it. ive got loud mouth exhaust, new lid, 3.42 gear, ls1 edit and thats it, and made around 311/315. i know ounce i get some headers, those numbers should pick up. i know fo a fact that an ls1 M6 can produce at lease 300 at the wheels, expeacily a ss.

didnt a magazine a while back dyno the corvette ls1 and TA ls1 or ss ls1 and the corvette dynoed well lower than the advertised power and the TA/ss dynoed 15+ what was advertised. its still on a webpage somewhere. came across it about a week ago.

My old 98 Z28 A4 had a Chokemaster catback (was on the car when i bought it) other than that bone stock down to the paper filter and it dynoed 295rwhp and 325rwtq. Yes it was an auto, no tuning no nothing.

I have a 98SS bone stock I dynoed 300rwhp and 316rwtq

With the eddition of a wisper lid the same day still strapped to the dyno
It Made 307rwhp and 322rwtq

Car had 26000 miles on it and it was done At NE dyno tuning 1/14/04

On a dyno jet. Did you dyno on a mustang dyno?

The car may just need a little attention.

I find this kind of funny because 2000SLPZ28 made 269 rwhp and 296 ft/lbs of torque and
6spd99formula made 276 hp and 307 ft/lbs of torque with their stock ls1 cars
I've got a 94 lt1 car with slp intake and hooker catback and that is it and i put down 270.9 hp and 314.4 ft/lbs of torque (take a look at link at bottom of thread) but i still get flamed when i say that i have run with and beaten some ls1 stock ls1 powered cars

by no means am i accusing you guys of this i am just stating that there are some ls1 cars that dont put down that much more stock than some lt1 powered cars but a lot of people still think its impossible to beat an ls1 car with a lt1 powered car stock vs pretty much stock.

sorry guys for the little rant

Thats a very stout LT1 it should be some ls1's so i believe anything is possible

With a Volant Cai and a Magnaflow cat back only I put down 301/316 on a Dyno Jet with 30K on the clock. 2000A4/2.73

My 98 did 304/321 bone stock, then 316/341 lid and cut out. An LS1 is and LS1 is an LS1.

oh definitely im not even close to saying that an lt1 equals an ls1, im just saying that when you match up an lt1 that is high on the spectrum such as mine pulling close to 271 hp and a ls1 thats low on the spectrum putting down 270-280 that its a drivers race no matter how you look at it.

i just got incredibly lucky when i bought this car it's somewhat of a factory freak and doesn't even have the notorious intake manifold oil leak (knocks on wood...) or any oil leaks for that matter the dyno was done with 70,000 miles on the clock

Formy 293...and that's on a 98

but you still only trapping 101mph...

true i was only trapping 101 mph but that time was from my first time at the track, the air wasn't so great that day, steady 10-15mph head/crosswind most of the day and havn't been able to get back since because its closed for the winter and i went to the track in october so i havn't had time yet. While i was at the track that day there were a lot of stock or close to stock ls1 cars running and i got to talking to some of these guys and stock or close to stock ls1 cars were only running 101-102 as well

this spring when the track opens back up im hoping to do a bit better and get some updated times but for the conditions of that day my car was running comparable with all the stock ls1 cars

My car is a 2002 A4 Z28 with only a lid and k&n numbers with 69000 miles

301.13 HP 322.58 TQ this was on a dynojet at 5800ft elevation!

lol, apparantly I have a factory freak...in the bad sense! Oh well...at least i can still whoop on a 96-98 mustang gt, lol!

Isnt there a huge difference between the dynojet dynos and a mustang dyno ? That is probably where these huge discrepancies come in...

My 98 A4 SS (poor first year LS1) made 330/333 with lid,headers,exhaust I was actually proud :)

Yours is on the low side no matter what dyno you are on....

For reference 00' M6 Vette, 65k miles on it, 311/325 bone stock.

either the dyno jet or the mustang dyno not sure which but one calculates wind drag ect i belive?

I have a question for some of the guys with autos dynoing on the low side, did the shop lock the converter during the pull? If the converter were left unlocked that's where your extra rwhp may have went. You're dynoing 20-30 rwhp under the "norm" (290-300 rwhp) and that's the range for an unlocked verter to lose.

Number two, it's nothing for KR to put you well under the 300 rwhp mark; and a lot of LS1s have unexplained knock retard (probably tuning related) bone stock. I know my old `99 was running consistant 13.2s @ 101 mph with ~3° retard, I finally got rid of the retard and droped to 12.8s @ 106 mph. It makes a BIG difference.

so your stock '99 (i'm assuming f-body since nothing was mentioned otherwise) with tuning ran a 12.8?

Judging by the thread starter's username, he appears to have an M6. No matter how you slice it, 276rwhp for a stock '99 M6 car is low, by at least 15-20rwhp, ....and there is likely something that needs to be addressed to bring the car up to full power.

Whats The Part Number on that Flowmaster? I want one of those.

i would get it dynoed somewhere else to see.

I dynoed with a lid at 296rwhp/306rwtq at cartek(everyone that day was down about 15 on hp)
Dynoed at Exotic motorsports with a cutout and went to the numbers in my sig, and their dyno was more or less more accurate than the cartek dyno for that day.

But the true dyno is the track, and i trap 108, so the latter dyno was right on.

Our cars are very similar! My 01 M6 SS Stock down to the paper filter 306.52hp 327.00ft. lbs of TQ

BTW: Whoever started this thread is :supergay:

Mine put down the numbers in my sig with 103k miles on the clock on a 98 degree humid ass day.

My friend Blake's 2002 SS, full SLP options, bone stock down to the paper filter with 20k miles on the clock put down 307rwhp on a Mustang dyno.

I got a 2000 Z28 BONE STOCK,except K&N FIPKII andTB bypass and dynoed 322hp/336tq....dynoed by livernois motorsports.It was also hot as hell,with no fan blowing on the car.

i think i got a factory freak, because i have a auto and with only a k&n fipk, hypertech and slp loud mouth i dynoed 325 rwhp and 340 rwtq

We'd be a good race...pretty close in #'s

My last 02 Z28 M6 Dynoed 294rwhp/318lb/ft with lid and muffler. Current 02 A4 car with similiar mods + tune put down 324rwhp/343lb/ft on the same dyno, similar mileage. Go figure?

^^^ Tune.....

i have a 99 ss m6 w/4x,000 miles on it completely stock down to the paper filter and i dynoed 305hp/320tq in 104 degree weather w no fan. i guess that good for the conditions. maybe get another 5-10 hp with cooler weather.

My 01' SS put down 307 RWHP with 400 miles on the clock. After installing a lid, K&N filter and a Corsa exhaust the SS dyno'd 336 RWHP (57,000 miles). My last dyno during a dyno tune was 348 RWHP and 375 RWTQ at 95,000 miles. Go figure.

bone stock i made 299.6 rwhp and 314.8 rwtq so yes it is possible

01WS6 Cam only and all the boltons rwhp 434 rwtq 418..............G FORCE HOUSTON tx
