So, how much faster....really?

[nastang87xx]

With launch control you should never be below 4K rpm on a dry road in a performance context.

Not using launch control. I should said on a start. I used to launch my Coyote at about 2500 RPM (no launch control) in 2nd gear on autocross starts. The surface can get slick from all the OPR and pebbles and stones being carried to the starting line. I have a feeling based on the Voodoo ' s torque curve, that isn't going to work as well. It will probably be a launch in 1st at 3000.

here is a hint, go see what the minimum rpm for launch control is.

The car will still drop rpm on launch. It's not an auto and doesn't have a converter. If not it would instantly knock the tires off. The clutch and the flywheel have to match up and if that were to happen without rpm drop at 4k rpm you'd either have wheels in the air (definitely not gonna happen) or tires spinning. Especially with such a tall first gear.

Do what? If you slipped a car geared to run 54 mph in first gear to hold 4k out of the hole you'll be buying clutches left and right. Lethal found that out real quick by smoking theirs.

That is not how you launch the car either. It must be launched over 4k and not much slipping of the clutch. Just preloading. Its no wonder people get horrible times in the gt or gt350. Nobody knows what the hell they are doing. Damn noobs. Lauching a car in low rpms that revs high is not how you get cars like that out of the hole fast. Only people with lacking experience in drag racing or a high revving engines launch like that.

As for this thread, the gt350 will walk a gt very nice, the gt350r even more so. The gt350 is a faster car then magazine numbers make it look. Race against one. Youll be very surprised how soon it walks away from you. They are not as close as the pathetic times for the gt350 that were shown in magazines.

I'd like to see the rest of the video. Can already hear the rpm drop coming.

GT350 R with the CF wheels is a good deal quicker than the non R. Car and Driver booked 60 in under 4 seconds with one I believe and the review sold the R as a considerable difference. First link scroll to the bottom and click for full test data:

Also motorweek is simple, I wouldn't hang on their conclusions. No challenger outside of a hellcat can touch a 350 overall. Challenger handles much worse at the limit than even a GTPP.

As for comparison, a non R 350 toppled a Z51 Stingray:

Add motortrend unanimously put the 350 over their best drivers car, the Z28:

194 looks and no reply.

So, I did some bird doging on the interweb myself.


GT350

0-60 - 4.3
1/4 - 12.5
Lat Acc - 1.10g
weight - 3796

GT350R

weight - 3710


GT/PP

0-60 - 4.4
1/4 - 12.7
Lat Acc - .96g
weight - 3825

Interesting.

Not sure where you obtained some of your information but a regular GT350 will not come up with a skid pad or lateral acceleration of 1.10G as this car does not have enough tire, wheel or suspension to support those types of numbers.

As far as the times that you have posted for a Mustang GT they seem somewhat optimistic based on what R&T and C&D have come up with. The only testing that comes close to that is Motor Trend and they come up with 4.4 and 12.8 @ 112 MPH.

Having owned a couple of 2015 50th Anniversary Mustang GT's and after putting them through the paces these 435 HP 5.0 liter Mustangs were not even close to performing like the new generation Boss 302 cars that I own and with only a supposedly difference of only 9 HP I suggest that either the 435 HP is overly optimistic or the 444 HP for the Boss 302 is underrated and I lean towards the latter. Personally I was somewhat disappointed with the performance of the new 5.0 liter Mustang GT.

In any event the 2015/2016 Mustang GT cars are a fine automobile but they don't come close to matching the performance of the GT350R on any level and you probably new that even prior to providing your post.

PP0001 dont forget the boss revved higher with its better manifold and it was lighter. Thats a nice difference in itself.

You know the GTPP will out run the Boss by a good margin on tracks, right? Terry Fair at Vorschlag ran 2+ seconds a lap faster than their 2013 Boss 302 on the same day with back to back runs by the same driver. I bet there was well over a 100lb weight difference between them. We know the Boss was quicker in the quarter.

listen to the bog as the car comes out, it's physics. The car with it's factory gearing will do 1 of 3 things.. rev high partial throttle roll off clutch quickly, bog and go (As seen above). Rev high, more throttle and use the clutch to aid in traction and getting the car moving without bogging at the cost of clutch, or 3, rev high heavy throttle and spin or wheel hop. It doesn't have the bottom end torque to defeat the gearing and it would take quite a bit more to do that, and it doesn't have the clutch to hold a heavy clutch slip (especially with more power). I don't know why we are even having this argument in the first place. It is anything but a drag car.

 

[xt6wagon]

Well most of us were using it to describe the relative difference in acceleration... but the GT350 holds up well despite having exactly the wrong things for the drag strip.

Expect a GT350 with slicks and skinnies to pick up more time than a GTPP. The fat front tires really slow the GT350 down, and the rear tires with stiff sidewalls don't take the shock of clutch engagement well. Magnaride also is tuned to turn into drag shocks in drag racing mode, so the non-base cars will pick up time with that too.

I'm really courious as to the differences between my 15 GT PP and 16 Gt350. Now my GT PP is SC'ed but still want to feel the handling and breaking difference. Straight line performance my PP going to be hard to beat. With a build date of 5/16 I'm hoping to have the Shelby first week of June, I'll report back.

Certainly agree with you about the capabilities of the GTPP on the track but the OP only seemed to concern himself with 0-60 and 1/4 mile times for the GTPP and the GT350 cars.

 

[Bullitt2065]

The GT350 isn't about 0-60 numbers and 1/4 mile times. At the end of the day, it's going to be barely quicker than a GT in those numbers. It's about lap times and the seat of the pants experience. Both of those it has in spades over a GTPP.
