My first Dyno for the WS6!!

[Ant'sWS6]

First thanks to Matt and all the guys at TTP! They were very patient with my newbie ass! They explained the whole Dyno readings and what to expect, etc.

Here ya go...

SAE Corrected readings = 315.79 - 324.81 rwhp / 334.24 - 343.11 tq (worst to best)

UnCorrected = 338.18 - 347.25 rwhp / 357.94 - 366.82 tq (worst to best).

Only mods are SLP Lid and K&N Air Filter. I'm proud of my girl! :)

Now let the modding begin..... :devil:

Kool, spray it now!!! 8)

[matt98ls1]

Uncorrected TQ numbers seem a bit high, but then again it was a good day to dyno (extremely cold)

I have to agree with James on this one too.....SPRAY IT! 8)

[Ant'sWS6]

I'm gonna post scans of the printed dyno reports but it won't be until I get back home sometime tomorrow.

Anyway I do have one question. From what I've read from various websites, the hp at the wheels is approximately 85% that it is at the crank due to power loss through the drive shaft, gears, etc. Does that mean that the dyno readings my car produced (324 rwhp - SAE corrected) are approx. 85% that it is at the crank? In other words doing the math does that mean my car is producing approx. 380 hp at the crank? I know this may seem like a dumb question but I want to make sure I'm clear on things. Matt at the shop was pretty suprised the car was making that much power and the tech running the car asked if I had put new heads on and was also suprised to find out it was pretty much stock.

Any info is appreciated.

Thanks

Ant

Well, you made 324 hp at the wheels, which is 1 hp away from what is SUPPOSED to be at the crank, correct? if thats the case then yes, you make a lot more up front. 8)

[Ant'sWS6]

Cool! Thanks Ian!

[Ian]

no problem man, now you owe me a ride :wink: :lol:

[matt98ls1]

your 15% drivertrain loss calculations are correct, except the car actually put down 338 uncorrected. thats what the car made on the dyno, at that moment, in that air....if you figure out the 12-15% drivetrain loss from that number, your car is making around 395hp and over 400ft.lbs of torque. I know 02's dyno a bit higher than previous years, but daamn! and especially since it was freezing cold in some dry air. Was the shop door open when it was on the rollers? lol


my car dyno'ed with just a lid and an exhaust cutout, and made 317hp/331tq Uncorrected, and 304hp/317tq SAE corrected. Those are around the average numbers for most LS1's (98-00), but yours seem a tad high (just a little shy of LS6 territory)



are you the first owner of the car? regardless, id be damn happy about those kind of numbers. was everyone else putting out some 'higher than expected' numbers?

[j0n]

there is definately something up w/ your t/a...did you buy it new?

equating a 15% drivetrain loss(m6) you're making 393.22hp/403.66ft-lbs at the crank with an engine that is essentially STOCK...im gunna hafta go ahead and say that someone done did mess with your engine in a very good way...no way in hell is there a stock ls1 brewing under your hood

[Ian]

maybe he has an LS6 block, which would give him a better oiling system. Less friction=more HP. It is a 2002 car...

[j0n]

haha great minds think alike(u posted while i was writing mine i guess)

ian - excellent assumption...iirc some 01s and 02s snuck off the assembly line with ls6 blocks...any way to check while the motor is in the car?

[matt98ls1]

LS6 block only will effect ventilation (negligble hp differences). The 01-02's do have a better intake, and also better stock exhaust manifolds than previous years. but yea, maybe he's got an LS6 cam in there :wink:


im anxious to see the powerband on the dyno sheet.

[NJSPEEDER]

get a complete set of bolt ons, hp tuner teh crap out of it and head back to teh dyno!!!!!!

congrats, those are very good baseline numbers.

later

thats an understatment!

[Ian]

I thought LS6 blocks had revised oil galleys? maybe I was fis-informed.

[Ant'sWS6]

no problem man, now you owe me a ride :wink: :lol:

LOL..you got it. Thanks for all the responses guys. I was really suprised it put down so much too. I'm not the first owner but according to the guy I bought it from...who bought it new in Sept of 2002 he didn't do any work on it so his word is all I have. The only other car there at the time...it started to snow soon after my car was run....was an Acura RSX that had some work done on it..the guys said it was running about where it should be (if that helps any)...and nope doors were closed :D

Haha!! can't wait til Monday to show my buddy at work (who has an 01 Mustang Bullitt) the print outs. :twisted:

Thanks again guys!

-Ant

[Ian]

number one: You better give me a hell ride! :twisted:

number two: rsx in the presence of a WS-6?!?! Please!

Number three: Bullitt boy is gonna **** his pants when he see the print out! :lol:

[1RawTA]

Ant very nice car.... that thing made some damn good numbers for just a lid and filter.. hopefully we will see you around at future dyno days

[foff667]

nice numbers...probably one of the highest dynoing "stock" ls1 cars ive ever heard of.

Hey Steve, it was great meeting all you guys, thanks for everything. Yeah you'll definitely see me around at dyno days and to do work on it.

That's pretty high. Nice. :wink:

[Fasterthanyou]

Nice numbers.
The LS6 block's windage holes are very important to making that horsepower. Imagine 5.7L of pistons moving up and down trying to "move" the air past the crank and rod... to make peak horsepower you need those holes. Any real racing engine has windage holes, the most apparent are motorcycles which don't displace a lot of air but at 14,000rpm they do move 100+hp worth of it and in a very tiny block!
I wish somebody would take apart one of these "01-02 LS1" engines to find out EXACTLY what's making them more powerful. Somewhere I heard they had LS6 intake manifolds, LS1 heads, LS6 block, thinner exhaust manifolds, and a cam imbetween LS1 and LS6... who's got the proof?

[BigAls87Z28]

The LS6 block was cast at a different plant in Mexico, while the LS1 was cast in Canada. The LS6 block used high speed-casting, or something like that. This actualy makes the block stronger to handle the higher output. The LS6 intake was also used on ALL LS1's after 01, but not all LS1's got LS6 blocks. By the end of 02, both the Canadian plant and Mexican plant use the high speed casting, so ALL LS1's after 03 are LS6 blocks with heads.
All LS1's have different cams. Vettes, Fbodies and GTO's, as well as Holdens all have different spec cams.

As for the dyno numbers, thats quite awesome. About spot on with a LS6, though I have seen Z06's put down a little bit more hp, usualy over 400hp, and that was with the IRS set up. Id say take a look at the part numbers on the heads and see if this engine might have squeek past anyone at Ste.Therese.

stock zo6's put down 345-365 to the wheels normally

Well, I ment Z06's put out about the advertised 405hp from the engine.

LS6 intake manifold is true. The exhaust manifolds used on the 01 and 02's are basically shorty headers. the cam also was changed for those years, to the specs of 207/196, .479 .467 on a 116. not exactly a radical cam by any means, but a little calmer than the one used in previous years.



However, please read... the LS6 block does not increase HP from the LS1 block. only difference is ventilation, which will not net any noticeable gains.

All dyno's are different depending on how it's set up by the operator. It helps to have someone else run on the dyno to compare to if they've dyno'd somewhere else, that way you'll know if it's dynoing high or low. It looks like you dyno'd higher than average. Even if you figure in a slight dyno difference, those are really strong numbers for a basically stock LS1.

Yeah, and I'll believe that joker when he gets a job at GM as one of their engine designers :x .
Doesn't increase horsepower, BAH HAHAHAHA, what an idiot. Horsepower is exactly what it does increase by improving the windage in the crank case. At higher RPM (where you're trying to get a peak hp number) there is a lot of air being displaced inside an engine. This windage gets really bad with big displacement and/or high reving engines. Trust me, an LS6 block will make more horsepower than a LS1 block or else GM wouldn't have done it.
