Good numbers fsusmithc2.

So far, the stock numbers I've seen for the LFX are looking pretty consistent! Those numbers are basically what an exact 20% loss at the wheels would be due to it being an automatic. Thats great.

I'm betting the LFX is a more consistent dynoer than the LLT was due to that new intake manifold and not getting so heat soaked. Engine runs more to its potential more of the time

or it could be that fussmith dyno is properly compensated for the correct drivetrain loss which I am almost positive that it is.. I really don't think the plastic manifold play a huge role in anything especially when it come to dyno because the car is usually cooled down after each run unless the dyno op is heat soaking on purpose. Out of GM's own engineers mouth, they said that the extra 11hp was achieved with bigger intake valves and more efficient cylinder head being that the exhaust manifold is integrated into the head.

I think it's all the same when it come to dyno. Some read high and some read low. It's always been like this from vettes to evo's. Perfect example would be abstract who dynoed at my place and got 249hp/216tq ASE corrected. Then fsusmith dyno 254hp/222tq ASE corrected. There's a 5hp and 6tq difference. Not much but still one is def lower than other but I'm sure they both have same 323

Have some updated numbers for the chalk board!

-Stainless Works Silver Ceramic Coated 1-5/8" Stainless Steel Long-tube Exhaust Headers with High-Flow Cats
-Solo Mach X-LLT Cat-back Exhaust with J-pipes
-Trifecta Engine and Transmission Tune (same tune as before so nothing different for the nitrous injection system)
-93 Octane Fuel
-Circle D 3200 Stall Torque Converter
-Transmission Cooler (Keep the transmission from burning up on hot days at the track during the summer)

Here's a link to the dyno video and results I posted on my garage on the club website:

http://www.h-towncamaroclub.com/show...ril-2011/page2

I'll be taking my car to the drag strip sometime this month to practice with the new upgrades (will be running on slicks borrowed from ARD for that day and then I'll need to buy my own set of wheels and tires for the track).

I don't expect to break any records with the Texas heat but early December seems a good time to do that with the denser air. So I should have plenty of practice before then. I'll start a thread on my build for the forums once I run it at the track so I can do a complete overview of the build and the nitrous system.

Also ARD's dyno has a habit of reading 25hp lower than other dynos in the Houston area.

Sweet Jesus!

TexasCamaro that is awesome...your car should be a rock star with all of those mods.

Can't wait to see what kind of times you can put down. By chance will you be trying some N/A runs in addition to your nitrous runs? I know the heat kills performance, but it sure sounds like your V6 should be capable of very low 13s or better even without the nitrous. 12s easy with the nitrous assuming you get a decent launch with 11s being within reach.

Keep us up to date in the V6 1/4 mile thread.

I am very familiar with ARD dyno from other members and specifically from our older member rolnslo. They use the same in ground bigger 248x dynojet that we use. You are correct, they do read a little lower but I don't know about 25hp. I think it's more like 10-15hp.

but you do have a nice amount of mod there. Can't wait to see those 1/4 times. Did you do any runs without the shot?

Nice.. and more for "the list"!

Was at a Car Show and they had portable Dyno Trailer setup, So what the hell i tried it.

Some how it looks low i dont see how it can be at the bottom of the stock range with the Mods i have. thought it should have been around 250.

Also its very jumpy does that mean anything? Can i have something wrong maybe?

The HP should be over my Torque right? Maybe it was just a bad pull and i should test on something more stable at a shop?

Dyno: Dynojet 224x

Its definitely low....who knows exactly why but the dyno chart looks pretty strange.

First off your torque numbers, while kind of low, closely resemble what stock output would be on an automatic..maybe a little higher than what I'd expect for stock, but for your mods I'd expect 10 to 20 more.

The HP should never be lower than the torque for this car. Usually on a car that dynos around 225 TQ, the HP ends up around 245 to 250 or more. One problem is it doesn't seem like they took the car to redline (should have gotten to 6,500 rpm or more, but they didn't) but even so, the numbers are still low.

That said...don't worry about it man...no dyno should be taken as gospel.

im really starting to think what I heard about our v6 making less than 312hp is true. I just don't believe that all these dyno jets read low. The king of numbers at that. I'm just glad I'm moving on. hopefully im wrong.

Thanks! I take this a first time test. I try to get a good Dyno done with all the needed information and then you can post that in the list.

Yeah I don't know....but if that is true but the LFX engines really are making 323 then that is a nice boost lol. So far, most of the dynos I've seen on the LFX cars seem to be fairly spot on in my opinion.

I'm dynoing my car on Saturday. I don't know whether to dyno in 3rd or 4th. I have never done this before, so any advice about dynoing is appreciated.

Rodgers Chevrolet is having an event on May 12th. Livernois is bringing out their portable dyno. For a donation you can make some pulls. I plan to get at least two pulls in to just see what it does.
