/sigh. Again I am not advocating for one power adder over another just clarifying that some of the comments have little to do with facts and are straw grasping.
My car makes 1,000+++ to the tire now so my car is definitely in the extreme. However I have included a picture from the other weekend where I drove over 210+ miles on the stock run flats at 900whp...wasnt hard to drive, merged with traffic fine, accelerated fine. Mine is a DD, wife is 8 months pregnant, ac seats blowing just fine running on 92 octane.
You are altering the argument to be about traction with shit tires vs “how does a PD blower drive”. A stock ZL1 on a street surface with stock tires will have a hard time hooking... however if you really want me to I will just launch in 2nd for you and “beat my chest”.
Also 10lbs is next to nothing so my comment about them being the same weight stands as well

You did say drive? Go ahead put street tires on your ride with say a normal wear rating of 220 take your cel, get a video of the tire jump into the car and do a couple of 0-60s or 0-100 and lets see you put 100+ more torque to the ground vs a ZL1 with no issues... 
IMO any normal tire will have issues at the bolt on a blower of any sort to a LT1, which makes more HP with any blower vs a LT4 at these boost levels (sub 10 PSI).
Stock GM ZL1 performance figures:
Coupe:
0-60 (manual)...............3.7 seconds
0-60 (auto)...................3.5 seconds
1/4 mile (manual)..........11.8 seconds
1/4 mile (auto)..............11.4 seconds
To be honest I don't know if these are easy or impossible to match on a street surface, I'll leave it to the stock ZL1 owners to chime in.
To the OP, any Supercharger will overwhelm the tire for any normal tire. My car is no faster FBO vs any level of forced induction to about 90+ MPH on a street surface with a normal 220 wear rated tire. I can do 0-60 from 3.6 to 3.8 no matter what is sitting under the hood. About a 2.0 60' time. |
The drag racers will immediately thump their chest about their drag car and how it performs on the race track with prep, which we all know is meaningless to a DD. For a DD (which mine is):
I so have a M6, so I'll defer to auto drivers on their DD; My car will break traction by easing into boost in all of 1st most if not all of 2nd depending on the surface. Basically 3rd gear is the first gear that I'm sure traction is NOT an issue. The is no advantage at all that I can see with a PD because it is simply NOT possible to floor my car till 3rd which is 80 MPH or so on my M6. I'm absolutely sure that the PD will break traction first going to WOT in any scenario, and I absolutely sure the PD will be backing off throttle sooner too. Because the torque is completely and totally worthless as it can't be applied to the ground at any legal speed on any normal tire which I'll define as a 220 wear summer radial.

Let talk about the "torque" Torque is NOT a unit of work. The trans and diff take HP (a unit of work) and can put out FAR FAR FAR FAR more torque that any PD instant boost. 1st gear is 2.66 and FD is 3.73 = 10x the engine torque, 10 TIMES, GM backs off the 1st gear on a ZL1 because of too much torque 2.29 or 8.5x So the factory back off say 625 ft-lbs of torque to the wheels on the STOCK supercharger via gear selection.... How about 2nd ZL1 is 1.61 vs 1.79 that is 6.0 vs 6.7 that is say 450 lbs to the wheels
less ... the factory can choose ANY gear ratio they want for their street car. If the Zl1 needed more in gear torque 1st and 2nd, you can bet that GM would have left the LT1 gear ratios alone.
You think the 4500 lbs Hellcat would need to get more torque (if we want to pretend said torque could actually hit the road),
https://www.hellcat.org/threads/manu...-thread.18815/
Yep the Hellcat has SIGNIFICANTLY less gear vs the 392 8.76x for the Hellcat vs 11.58 for the 392, so that means Dodge backs off 1st gear wheel torque by 33%..... roughly a 3x LESS engine torque to the wheels or 2000 ft-lbs to the street tire... If the factory thought they could use the stock PD torque to move the car, they would have left the 392 gear ratio in place. The torque IS not usable in the first two gears. I have given you two factory examples and my personal experience....
QED
I have no comment on what DR or slicks do on a prep track, and that is not the question.
I considered all blowers and my primary decision was the support and the tuning. I went with Pray and I am very happy. I was close to going with the stock blower and ADM, and there is a glut of these so once again IMO, it is your tuner and what type of support. There maybe a glut of all the older aftermarket PDs too (as people are going for bigger blowers now), so they all would be good. I can see that DIY the centri is pretty easy to install.[/QUOTE]
