Gt350 Looks questionable in the hp department or am I off?

Not at all. I never said it was stock just like I never said the zl1 was stock. Fact remains the best time for the gt4 is better than the best time for the zl1. Even though the zl1 has way more power! Just proving you don't need big power to have great performance!
Oh I definitely agree with that. The most fun cars I've owned were about 425-430whp with steep gearing, big tires and full suspension. I've owned 650+Rwhp cars and they get old to be honest. A quick, great handling, nimble car is much more fun.

Exactly. I can't even fathom this irresponsible thread.

$200k 500hp GT3RS Great Amazing Spectacular
$65k 500hp GT350R questionable horsepower!

I also like the fact that op questions hp without owning the 13/14 GT500 or Hellcat. I mean his 12 had 25 more hp when he purchased it? And he needed a blower to get it that high!

Just for kicks I wouldn't mind seeing the voodoo and LS7 crank hp dyno overlay, but you have posted a whp dyno from a c6z. We don't have a whp dyno from the gt350 so that's not a fair comparison yet.

I mostly posted it just to see the power band. Thanks to big reg for posting graphs overlaid. Something tells me that the huge lull before 3500 won't be that pronounced on the Voodoo torque curve either. We'll see.

Unless the gt350 now only makes 410tq, that graph is wrong. I think that overlay is from the press release which had torque scaled inconsistently with hp.

The graph here looks like 410-415tq. It's not a huge difference but it's more than noticeable when comparing a properly scaled torque curve. Notice how both hp and torque don't cross at 5252 for each graph? The gt350's graph crosses at ~5750rpms.

The gap from the top of the ls7 curve to the 500 line is an accurate 20 value on this graph (481 tq rounds nicely to 480). The gap between the voodoo and ls7 curves is much more than twice the gap from the 480-500 line.

If we are going to compare dyno graphs, we need them scaled equally.

Now all of that said, keep in mind the z06 ran a 3.42 with a tr6060 running 2.66 1st and 1:1 4th. The z28 runs a 3.90 with a 2.66 1st and 1:1 4th.

The gt350 runs a 3.73 (or 3.55, can't quite recall) with a 3.23 1st. 2.3 2nd (iirc) 1.6 3rd (iirc) 1.3 4th (iirc) 1:1 5th (fact) and .63 6th. Basically the 5-10% difference in torque is mitigated easily by torque multiplications thanks to gearing. Let's also not forget the gt350(r) will be 3675-3525lbs respectively. That's 2-350lbs lighter than a z28, and only about 3-400lbs more than a c6 z06 was.

Keep in mind z06's were notorious for feeling twitchy and overly tall geared but prone to oversteer, and z28's are often considered slow (straight line) for $75k. Mid 12's at 115-118mph isn't slow but for $75k it isn't fast.

That brings us to a $47-62k car that will likely run 11.75-12.0 at 118-122mph. Morons that think it will suck at the drag strip need to consider the variables. Super sticker micheline pilot sport +2's in a 305/35 60 ft way harder than the old boss's 285's so 0-60 can only improve.

Moving power and torque north in the rev range can only aid 8th and 1/4 mile since we know traction won't be an issue. And anyone worrying about bogging a car that has the potential to launch at up to 8,000 rpms can rest their weary tired little heads because it ain't gonna happen in a car geared for 58mph in 1st at 8250rpm with 429 tq and 526hp. If the mach1 from 2003 couldn't overpower slicks with a 4k launch on mt et streets with it rev happy 4.6 making ~300tq (a small few of those cars were running 12.7's@105's on et streets back then with stock or maybe catbacks, mm&ff ran a 13.1 on stock tires iirc), rest assured the gt350 won't be a slouch at the strip either.

It's funny to me how many people are worried it won't do well at the strip when:

-it has a smooth linear na powerband
-it has super sticker tires
-it's geared short to accelerate hard
-it has a dialed in firm chassis that won't hop around like an uncoordinated raccoon drunk on budwiser
-it's already been seen running 11's with even smith behind the wheel at atco or somewhere similar.
-it has 526hp
-It has 429tq
-the last boss had 444 and 380tq and ran just fine with similar gearing in a car weighing the split difference of a gt350 or gt350r
-the last boss had hero runs in the 11.90 range at 118.
-the gt350 is making 444hp by like 6,000rpms
-the gt350 is above 380tq for roughly 3,000 continuous rpms-about 4,000-7000rpms

You are not suggesting that the GT350 could see stock 1320 times that equal the stock 11/12 GT500, which the op spent his hard earned money on, are you?

The Magneride equipped cars also have a "drag" setting that helps the car squat on launch, then firms back up before the first shift to help maintain control. That should help nicely.

And missing 700 RPM and in turn, 60 horsepower. RCF is an M3/4 fighter. And a piss poor attempt for what it's worth. The GT350? Much more focused.

Im pretty sure Lexus never intended the RC-F to be a M3/M4 fighter. Lexus is known for doing their own thing and nicely filling a niche that has no competition. There is a reason the new GS-F will have less than 500 HP. Hardcore race track type guys will opt for the M5 anyways. Lexus does their own thing.

Op you are off, waaay off. 700 NA hp out of a v8 in a 50k car?? Even the 233k 458 italia only makes 570hp.

Go buy a hellcat or wait for the gt500, this isn't the car for you

I'm on the porsche forums as well. When the gt3rs came out, nobody on those forums were yelling about how horrible and underpowered the car was because their 911 Turbo S had more power and would outrun it at the drag strip or red light. Or how their 5-10 year old car with xyz mods that they purchased for way less than a new gt3rs will destroy it on the streets. These forums are so comical. Smh

No doubt. Everyone here is a multimillion dollar businessman or an engineer who knows how to create cars from scratch and run Ford better than they do. Do these people even realize what Ford durability testing looks like?
EcoBoost also endured Ford’s standard engine durability test signoff. Back in the dynamometer lab, the 3.5-liter EcoBoost V-6 went back up to full revs – and maximum turbo boost – for a real endurance test. This time the duration was a bit longer – 362 hours at full throttle. That’s like running the 24 Hours of Daytona for more than 15 days straight.

I would like to see how op's modified engine handles that test? 360 straight hours running at redline. Every car Ford sells, the engine has passed this test.

The sky is falling, ford only added 82hp to its mid level track toy.

Why does everyone think it's a mid level track toy? It's the fastest street car Ford has ever produced I'm speaking of the base GT350. And the R is significantly faster!:beer:

Because it will not be the fastest in a straight line and for some that's all that matters.

It's mid priced (will eventually be) so mid level

It's a track toy so track toy.

There's no shame in a mid level track toy, the boss was better overall than a gt500 until the trinity

The 11/12 GT500 was faster on track for peak time than Boss LS...the GT350 is a stronger performer than the 13/14 GT500. But hey call it what you want.

Nothing is better than the GT500 cough cough.

id bet 11/12 gt500 wasn't decidedly faster and driver enjoyment wise id imagine a boss felt more enjoyable to drive but I've never lived with either for weeks or months

Someone already mentioned it. Hop in to one of those "low hp" Caymens and let us know how it goes. What feels and performs so well in many of these high end track cars is their ability to pull from any RPM and give you power whenever you need it at all times. Peak hp only wins dynos, not races. The gearing and suspension will polish it off nicely and make it feel that much faster.

When you guys see the performance this car is capable of in its intended environment (road track) you'll realize that 526HP is way more than enough.
