Im interested in knowing how the LS2 put down 371 basically stock. I have a friend with an 06 GTO that made 340 bone stock which is the norm for a LS2.
I just got done reading where GM HighTech Performance just did LTs & CAI on a LS2 GTO & made 375.9/372.7
My 6.0 just made 380/380 (mods in sig)
My Buddys 02 Z06 with LG LT's, Vararam, 3.90s & tune made 371rwhp
Good Kill though!

so the gto made 371 BEFORE adding the longtubes that were on it for this race and also the track outing...and the mustang made 400whp. gto trapped 113 and stang trapped 108...?
wow, i think yall got some generous dynos up in there.
good vid, nonetheless. keep the kills coming on these heavily modified, poorly tuned and/or driven ferds. at least that seems to be the common denominator here.

And to everyone calling BS, you guys way overthink things. If I were to guess a percentage of motors that are built well and run top notch compared to ones that were built half assed and run ok half the time, I'd say the good ones are about 20% of whats out there. The fact is that most kids I've seen with heads/cam 302s, 331s, or 347s run like *******. Nobody knows how to build them.
Not sure why the car ran as shitty as it did, but I watched it make 400 rwhp last summer, yet now it runs like a turd with no changes. All I care about is that the barely modded GTO has now shnapped off two **** talking stang owners. NEXT!

Or maybe it's just the fact that the LSx can never lose...
Both cars started in 2nd gear at around 45 mph, and lifted at around 120ish. GTO has stock 3.45 gears and stang has 3.73's.

Do the math, you know it doesn't add up.

I think he knows it doesn't add up that's what he said he's not sure why the cobra ran as shitty as it did. Iv personally seen 300hp cars beat 400hp cars does that mean the 300hp is faster? No. But anything can happen we all should know that by now. Maybe the cobra saw a honey badger cracking pastatios and got scared.

Oh I'm well aware it doesn't add up. It's got him and all his buddies scratching thier heads...problem is they aren't real die hard car guys that would throw it on a dyno to see what was up after that, whereas I would have been at a dyno the next day.
LMAO!

The GTO was on the same dyno I've been using for years, and I've tested it against other Dynojets in the area and it always reads very close. If we just want an ego boost, there's a local shop with a Mustang Dyno that fudges their numbers as long as they work on your car
Also, the day before the GTO dynoed, my G8 made 357, and right before this GTO dynoed there was another one with bolt-ons, including headers and a FAST intake, that put down 389. He seemed a little disappointed as before he told me he was shooting for 400. I thought the numbers looked good.
I can say that I was there when the GTO was dynoed and we were all surprised. Looking back, it doesn't seem too crazy to me. They've been known to dyno 345 stock, so 358 with a cold air and 371 with a tune doesn't seem way off. My G8 picked up 15 rwhp from a similar cold air system and then another 19 rwhp from a tune (and went over 3 mph faster at the track on a warmer day than it went stock).
When the GTO was stock (my car having bolt-ons) I was able to edge it out, but after he did the cold air and tune he walked me pretty good.
As for the Mustang, I have no personal knowledge of it, but like NightmareTA said, I'd be out the next day trying to figure out what was wrong with it after seeing numbers like that from the track.

The sn95 was a turd I had a 302 in a 95 cobra with tfs heads unknown cam and gt40 intake! Trapped 105 with a 4:10 gear! No numbers and no tune! You just dont build a small cube sbf in them cars and expect good results

You can, but as many have said it's all in the combination of parts.

IDK man, this car is a strong runner. Even our tuner told us that if we were lucky it would make 350 after the tune when it was intake only. He was in disbelief when it made 359 RWHP untuned with just an intake. After the tune it was 371. Guessing it's around 385-390 with the longtubes now...but dynos aren't everything. The track times back it up trapping 113 mph. Just a strong car I guess.
