yes after the cats and we leave it on the safe side....thats not TOO rich... 12.8 is a good number...

 

business couldnt be better mike.... im doing all kinds of fun stuff... let me know when your ready for your next mods and we will works something out...

 

Awesome Fran Thanks Man. I'll be in sometime this week.

 

Congrats on the mods. Those are some pretty stout numbers for a cam only. I'm very happy with my cam only setup from LG even though it is a few HP below what you are showing. See sig for my setup and numbers.

Merry X-mas

 

Both of those dyno sheets were with the factory cam and exactly same mods.

 

well i dont know what to tell you on that one.... once we change the injectors we are goin to retune it and dyno it on the same dyno then as soon as we pull it off the mustang dyno we are taking it to a dyno jet which is 5 mins down the rd. so the weather will be the same even though that doesnt really matter with it corrected....

 

Good numbers and my only comment is to agree that a dyno is a nice tuning tool to see the before and after. What did the car dyno before the cam?

 

Why?

 

It would be most interesting to see the results on the dynojet before the injector change and retune in order for us to see the difference between the two dyno's and obtain an accurate assessment of engine output.

This would put to rest any controversial debates on this thread regarding your original output claims

"If you retune and change injectors prior to going on the dynojet, how can you compare the two results on equal grounds ?"

 

I would also be very interested in these results. However it might be more than the owner/tuner is willing to do. They really have no reason to prove it to us if they don't want to. The numbers are a tad on the generous side of similar setups we've seen, that's all.

Cameron, go to bed would ya...

 

Can't had tea, big mistake..

 

455HP 414TQ on a mustang dyno.

Its FLYWHEEL ............not rear wheel . A LS2 rwhp is around 340 on a good day. The above was posted on another site. You notice he didn't claim rwhp over their. That cam and header w/cats package will be 390-395 rwhp and 370 or so rwtq. No way will that package add 115 to the rear tires unless it had a bottle for Christmas cheer.

But its still a good bang for your buck.

 

so we can see how close the 2 dynos are since people on this web site dont beleive us....

we are goin to... we are goin to retune it on the mustang dyno and see the diff from the 455 RWHP now then go right to the dyno jet....



um yeah its deff RWHP.. why in the world would i EVER state Flywheel HP numbers.....and if you think an ls2 with that cam would get 390 than you are honestly VERY missled.... you might want to read up on current stats b/c your completly off...

 

So, what your saying is with that cam and header package, that C6 with a LS2 400 bhp, now makes 510 bhp,(12%) which is more than a C6 ZO6. Really, now.
That cam,(its mid size) maybe 20-25 rwhp and those headers w/cats maybe 25-30 wrhp. CAI which is on, really doesn't come into play, as it needs some speed before it starts to work. A ported TB might give you 2-3 rwhp, on a very good day. A ported TB usually gives better throttle responce. New mufflers are for sound, thats all.
I think you got an Elf around, who fell outta his wagon.
To get above the 450 rwhp mark, requires a big cam, and AFR or similar heads along with all the other bolt ons. Thats a fact, backed up by alot of posts with dyno numbers. Just seek and search and you will be informed. When it thaws, show us some mid 11's times.

 

Fran,
I have 05 6 speed, same exact cam, melrose headers w 3" X pipe and random cats, under drive pulley, ported TB. Only difference with your car and mine is the CAI in which I have Halltech Stinger. I pulled 420 rwh and 399 torque on dyno jet.
What tuning program are you using and any ideas where mine could use adjustment ? AF was at 12.5.and tuning done with EFI live.

I have asked this once and never got a response.

Tom

 

Save yourself the effort and throw down a killer 1/4 time, put it on YouTube. Unless you get a non-believer to pay for the second pull, put it on the track and see what she'll do. Throw down a big 1/4 time and next thing you know, the world will beat a path to your door.

 

Well I dont know Fran but my shop just did the same cam in a 06 GTO
It has all the boltons aval. except a ewp.

It dynoed on Dale Cherrys Dynocom at 455RWHP SAE Corrected
Now I dont know what the exact weight of my customers GTO is but it only had the spare/jack/fuel brace out of it and it was on 17's all around with DR's...I'd imagine it was right about 3800lbs with my customer in it (235lbs.)

Wanna guess what it ran in good but not great air..
11.64@119 so I would say these Dyno numbers are pretty honest

 

Those are some very solid track times. I've got a G5x3, 436/392 as shown above, 3.90 gears, 3430 race weight with me in it, best time in 2000 DA air 11.709@121.04, 1.782 60 (admittedly lousy).

How'd you get that 11.64 in a heavy Goat? Is it a stalled Auto?

Here's my point in my questions above (besides wanting to know) - the track isn't such a great barometer, because my car runs .2 and 2 mph faster in 800 DA weather vs 2000 DA, and autos vs manuals are significantly different ET's and trap speeds. And particularly with manuals, driver skill has a ton to do with it (or lack thereof in my case with my measly 1.7 60's). There is some consistency with trap speeds but it's really weather dependent. It NEVER gets to 35 degrees here in S. Fla so there's no chance I can set a MPH record like the NE guys can. I don't think anyone would argue with me that 35 degree 15% humidity will produce more power than the lowest I've seen at the track of 67 deg and 55% humidity.

After years of reading threads and paying attention to track times and dyno numbers, I actually believe a Dynojet, when corrected to SAE, smoothing 5 is hard to cheat and a good barometer of one car compared to another. 455 rwhp, measured on a Dynojet, on a cam only LS2 (no FAST) would set a record I'm pretty darn sure.

And records are meant to be broken, so if Fran does it, I'll be VERY intersted to learn how if he's willing to share some details - maybe he knows some tune magic, and I'd love to hear it!

 

Its a LS2 GTO and its a 6sp and it holds the 6sp cam only record as of today

It really dynoed 455RW which IMO was insane...I didnt wanna believe the numbers either but once the car ran 11.60's@119 in 55 degree air I was shocked....

Tonys car is legit,its gotta be right about 3800lbs with Tony in it.
I am adding the same cam to my 06 GTO A4 with the same boltons..

Here's the list of mods to Tonys 06 GTO
06 GTO 6sp
KN CAI
160 Stat
Pacesetter longtubes/no cats/loudmouth
Comp 232-234 595-598 112+2
Comp 928's/Comp 772's
Comp 7.425 Pr's
LS2 chain
Fast 90 intake no porting
GM 90 TB no porting
LS7 Clutch w/BM ripper
Slp pulley
Tr55's
Dale Cherry tuned

Thats it
So its believable that Fran got the same numbers...

 

I can absolutely believe 455 rwhp with a FAST - that's 19 over what I have cam only ported intake, and I've got 3.90 gears & cats. That makes perfect sense. My car is right at average for cam only LS2's.

455 on a factory intake with cats doesn't make sense, but hey, if it is then I'm all ears to learn how.

To get a 11.60 in a Goat is a real feat - your friend Tony should be proud! That's awesome.

What was his 60ft? Had to be 1.5x... hard to get in a Goat for sure! What was the launch technique?
