I'm going to try something different and see if it takes root.

I've got the '82-92 F-body 1/4 mile times list in the racing forum (Link Here), but the truth is a lot of people don't drag race, and even fewer people have a drag car suspension to pull a good time.

But I'll bet a lot of LS swappers have dyno sheets from when the engines were tuned. And I'll bet even more people would like to see how different combos perform.

--> Post up a description of your engine build with dyno sheets. Also say what kind of dyno was used for testing, since results can vary.
--> Type of transmission, and rear gear ratio. Let people know if the dyno run was in a different trans gear than 1.0 ratio.
--> No speculating, please. Just the folks that have documentation.

I know, the dyno can lie and the drag strip doesn't. But I think this might appeal to a broader audience and get more responses than the 1/4 mile thread.

Running on a dynojet in 4th gear peaking 19psi for 766hp/811tq

 

Thank you for getting this thread going.

 

Junkyard 33k pull - stock 06 GTO LS2 (includes DBW) w/ stock 4L65e and had 9bolt 3.27 at dyno time.
All stock (even accessories) w/ CAI and SW LS7 exhaust.
I asked for a no knock-retard tune (conservative). The plateau with no peak shows it continues to pull. When I get to the point of HCI, that should wake this up considerably.

 

Impressive numbers 86white! I didn't even get half of that.
My results were 340hp/320tq. The torque number shown on the dyno result reflects a spike and isn't accurate. 320 looks to be the actual max torque.

I went with a 5.3L LC9 engine.
DoD and VVT deleted
Texas Speed and Performance cam 220R 114 LSA
Hedman long tube headers
T56 with stage 2 rebuild
3.73 axle ratio

 

Stock bore 02 Ls1
PRC 2.5 243 heads, stock Ls6 intake, 42 lb injectors, TSP 228/228R cam, Speed Engineering Longtubes.
431/410
Red line with cutout closed
Blue line with cutout open.

 

Here is results of two different cams in the same engine. Both were taken on the same MD-500 Mustang dyno.

427 6.0L stroker (4.125 stroke)
PRC L92 heads
FAST 102R with the long runners
T56 , 3.73 rear gear
Hawks 2" primary headers and single 3.5" exhaust

First curve is with a TrexV2 cam (450 RWHP , 437 lb-ft). Never ran it at the track. This was really an LS1 style cam and didn't work real well with this engine.

Second curve is with a CamMotion 240/256 114+3. Tires would not hold more than 400 lb-ft, so dyno reported only 478 RWHP with tires spinning. Car went 125 mph in the 1/4 mile at about about 3700 pounds. Later discovered the cam was advanced 5 degrees so that really hampered top end power. And the engine would have been better off with mid-length runners in the FAST intake (instead of the long runners). There was a lot left on the table with this combo and wish I could have seen what it could have done when set up right.

 

6.0 lq4
11:1 compression
243 stock heads, .660 springs
ls6 intake
224/242 cam
42# injectors
4l80e with 3600 stall
converter unlocked on dyno

 

Thanks, I wasn't expecting to hit over 700whp with my setup at first with pump and meth.I will do a spring dyno pull to see if its still making the same power and healthy after I swap my new diff in.

 

Thread bump

 

Same MD-500 Mustang dyno as was used with my last engine.

LS7 stock bottom end
ported Trick Flow 260 heads
ported MSD LS7 intake
Comp Cams 240/254 114+3 (LSG profile)
T56 , 3.73 rear gear
Hawks 2" primary headers and single 3.5" exhaust

Tires would not hold more than 420 lb-ft, so dyno reported only 570 RWHP with tires spinning.

 

Which 84mm On3 turbo is this?

 

This is a useful thread! I was looking for something like this when I was getting ready to put the lsa on my 5.3.

Gen 3 LM7 5.3, craigslist special, 300 bucks.
Stock bottom end.
Stock 94’ T-56 converted for an ls motor
Strange S60 rear with a trutrac and 3.73’s, stock torque arm
Monster Clutch triple disk
799 heads milled .030
Arp head studs with ls9 head gaskets
Tick Performance stage 2 turbo cam
Brian Tooley valve springs, comp trunions, comp pushrods
Walbro 400 in tank, 3/8 feed and return, Deka 80 injectors
Lsa blower untouched with cathedral adapter plates, 2.4 upper pulley, Lsx Concepts race drive, Zl1 lower pulley.
Aem meth injection running boost juice.

Made 15lbs on 93 pump gas. Best it ran was a 10.8@133 before the old clutch started slipping. Put down 529/510 at the tuner. I have a 6.0 going in now with a blower cam and ported heads. Should be fun!

 

Its their billet 84mm..I had previously their 78/75 and I loved it..Got an offer on the turbo and decided to try the 84mm as a direct replacement.It performs great 2yrs later and no issues. My only gripe with the On3 turbos..if you want to really call it a problem.they are very quiet compared to other brands. Its good and bad..good for street manners..but when full tilt..I expect to hear screaming jet.. not a high pitch whistle lol.

Yes, definitely, but need more people to share info. Imagine how useful this would be if it had been started 15 years ago?

 

Screw it, I'm just going to start dropping some in here.

Well, since we’re posting documents about performance, I might as well come clean. Last October, I did a burnout for the first time after the LS swap. The LC9 did not disappoint. Unfortunately, the motorcycle cop became visible a few feet past the stop sign just as I was regaining control of the rear end. I’m in my late 40’s and so ashamed!

We stuck with the 3.2" pulley for now at just over 5 lbs of boost as i am maxing out my airflow sensor limit in the GMPP OS and don't want to do scaling as i am working to upgrade to a OS without this limitation.

So we made 566 rwhp in the end with the 5 lbs of boost. That is up from my 448 rwhp last year. My numbers over the past couple of years all at the same facility with the same dyno are,

2009 LS3 Crate with GM Hot Cam - 389 rwhp / 370 rwtq
2010 Add ported heads and Texas Speed Cam - 448 rwhp / 408 rwtq
2011 Add TVS2300 at 5 lbs of boost - 566 rwhp / 489 rwtq

So still some room to grow over 600 rwhp if i desire, but it is already pretty stout driver!

Posting for reference only. Here is a large collection of naturally aspirated engine combinations that run 10's with a manual trans.

Unfortunately I do not have the dyno sheet handy, but no big numbers. If a sheet is needed, feel free to either delete or asterisk mine, also I'll attach the sheet if/when I find it.

Tuner said there was more in it, but was having fits with the '98 pcm. I got a '99+ but haven't repinned the connectors yet.

If this helps lay a baseline for very mild build, then I won't feel like I'm embarrassing myself too much.

 

That seems way low. My 2002 Ls1 with stock exhaust manifolds, Ls6 intake... basically bone stock with dyno tune did 340 rwhp and 350 rwtq in my Iroc.

oh, and a fresh custom aluminum drive shaft since mine exploded on an earlier run...


Spun on the previous (blue) pull.
381hp, 360Tq, adjusted for the weather it would be in the low 390s.

Really wanted 400, but this is close!

 

Yeah, mine spins on dyno too. If you figure out why let me know. I can't get a clean run.
It must have something to do with suspension and the way the car is strapped down? Maybe roller diameter being a little on the small side?

 

Not sure why... But since there isn't any weight transfer to the back, I would say that doesn't help. And yeah, maybe a smaller drum diameter takes a bit away from the contact patch.
Tires are brand new firehawks, 255 wide at 30psi.
But, they took serpentine belt dressing and sprayed it on the tires and drums and it didn't slip on the following run.

This shop is holding a dyno day this weekend with some 1000+ hp cars expecting to show up, and they hook up I guess.
