Wow! a lot of butt talk. why are we so ****.


Sorry guys couldn't resist!!

I had the exact combo as you and I made 392rwhp when I had my LS2. This is all in fun and information. I really don't think anyone is upset with your times. they don't want you to get Butthurt (upset) when your times are adjusted. it seems all comments were just a little advise from people who have your set up. I have A6 LS3 with headers and tune. I put down 396. but I run consistant 11.8s. Don't get so offensive. We are all here for information purposes.

Did your factory LS2 go back into the car? You wrote that your car was without an engine for several months. This would clear up the speculations of your dyno numbers of a stock LS2 w/ bolt ons.
Today 02:13 PM
First my mods are: longtubes, x-pipe, stock axle back, varram, slp underdrive and a ls7 clutch, cutouts... I do believe that is all.. and a LS3

Who did the Mod? Because I believe that this car has a cam. It is impossible for an LS2 to muscle 430 rwhp without a cam.......noway. So you must not be the initial owner. Nice power though

I put down 399/403 with headers, Vararam, unported Fast 102 and a tune...but my numbers were corrected. Ironically my trap speed was 118 with a 2.0 60' hmmmm

With a good clutch and on a sticky tire you should be running very low 11s/high 10s at well over 125mph with that kind of power/torque so many of us will be looking forward to the future results of this groundbreaking bolt on combination.
One of the best ways to back up/prove one's dyno numbers is drag strip ETs and especially trap speeds, that can certainly help shut any doubters up.

OK, my car put down 365 rwhp on the dyno. But it ran 12 flat at 118.75 mph. Trap speed is the best way to figure out what kind of power your car actually puts to the wheels because ET is too dependent on your launch.

If your traps are 110mph you are probably putting around 340 to the rear wheels. I guess that's why they call a dragstrip the 1320 foot lie detector.

Your car has similar mods to mine, it really should be putting down around 380 to the rear wheels (mine is an auto so it should be lower than yours) and it should be trapping at least 118. There is something wrong. I really don't care about your dyno numbers, dynos are just tuning tools, the absolute number doesn't mean a thing. A dyno is used to compare power before and after a mod. What concerns me is how slow your car is with those mods. There is something not right with your car.

EDIT: I just noticed you said you let off in 3rd gear before the finish line. Hopefully that's all that is the problem. Fix your clutch, go back to the track. With your setup you should be running high 11's and around 118 to 119 mph. Good luck, be careful, and have fun!

I'm also not quite sure why "butthurt" is your go-to phrase or why you think anyone in this thread is "butthurt" over your exaggerated dyno numbers. We're just trying to educate you on what your cars setup would be making if you're interested in making comparisons to others on this forum.

You're still assuming the dyno is only off by 20rwhp uncorrected. I just hope you're not dissapointed when you hit the track and don't see 122-123mph trap speeds that a 430rwhp car should be producing.

You are correct in saying that on that dyno, on that day, uncorrected it made 430rwhp. I believe that 100%. Talking uncorrected numbers allows for no basis of comparison though. We're only trying to help you in understanding your car better when we say that going by the standard (SAE) your car will make around 385-395rwhp.
I don't really believe that it is making 430whp corrected or that it will make 450whp with a fast, I just thought that it was pretty cool so i wanted to share what the car made on that day.. uncorrected of course.. I wasn't trying to compare my car to anyone elses or even claim superiority in any way.. Just that i thought that my car being able to produce 430whp under any circumstance with the current mods was something to be proud of.. Now the corrected numbers are another story.. And yes i fully expect nothing above average SAE..

Yes, a factory ls2 went back into the car.. the only addition (does not add power) is arp rod bolts..

But, I agree, the dyno is off at least 40 rwhp (unless the OP slipped a cam in there and forgot to mention it).
I don't think it made 430whp... The dyno said it made 430whp.. Would you like to come to southern ms and give it a shot? Then you can tell me if it made 430whp..


In all seriousness that number is uncorrected and just what it made on that given day.. I will dyno it again sometime and update with corrected numbers..

Glad you re-read the post.. Also i will hit the strip as soon as i get the clutch issue fixed and some radials...Thanks

Who did what mod? you mean the engine install? Well then I did and no, no cam other than stock in my car... as stated before the numbers are uncorrected and i expect the dyno to be reading a bit high... I am still pretty impressed with the overall performance for the problems i was having at the strip and hope to be back problem free soon..

I doubt the low 11's or high 10's or even the 125mph... I'm optimistically hoping for a 120 trap and a mid 11 second pass..

At any rate, it's not a record setting car or anything like that.. I just caught a friendly dyno on a perfect day and thought I would share, unfortunately there are people on here that like to rain on my parade and deny what took place... I can't really help that, but i can try to make sense of it in my own mind and use the knowledge that i have to create a reasonable explanation for what took place.. that being: friendly dyno, great weather, and uncorrected numbers...

Seems to me that you only came to that conclusion after the several posts informing you of the reality of the situation. Your first posts did not indicate that you didn't believe what you were telling us. It sounded more like you were "butthurt" because your results were in question. Why people get so offended when someone doesn't immediately believe what someone else says on the internet.....?

Anyway, regardless of the originating intention, as long as you are now aware of what may or may not have happened. Dyno wars are futile battles. Understanding what they are used for and how to compare results is more important than highest overall numbers.

Now fix your clutch and get back out there!

I think Glenn stated it best when he typed "Dynos are just tuning tools."

Sorry for the rain on your parade but being a CF member for serveral years I have realized that many of us have no respect for "Dyno Queens" as many are very skeptical of dyno numbers.

Once you fix the shifting problem and get a set of drag radials I am sure you will be very happy with performance of your car

A 3rd gear pull would actually show lower numbers, not higher. Its just like putting a steep rear end gear in the car, numbers go down.

A taller rear gear actually increases dyno numbers. A shorter gear like 4.10s yeilds lower numbers. 3rd gear pull would make lower numbers because its a shorter gear not steeper.

A steeper gear is a shorter gear, its the same thing. I know a 4.10 would show lower numbers than a 3.42 which is my whole point. A few friends and I ran a mobile dyno for a few years, I know how it works.
