Yeah be careful man. I'm sure it will be a handful after all that especially with those tires.
The Falkens I have aren't that bad man. I can spin them at 25mph, but with as much power as the car is putting down, I'm pretty sure I could have spun the M&H drag radials too. I just chock it up to the hazards of being blown, lol.

I didn't like my Coast Driveline 4" so I'm back to the stock shaft.
I had some rubbing, but only when the suspension was fully compressed.
I'm not lowered either.
It was also kind of loud. It's a big 4" aluminum tube that kind of amplifys all the drive-line noise... A bit of vibration at high speed also.

Tire spin is fun but if you think about it really it's not a good thing. If you can't keep the tires from spinning once you're up into your RPM range and moving then you are sacrificing power. Big time. And you will lose races because of that if you care about that sort of thing.
Tire spin at 4500+ rpm is bad. If it were me I'd try to do something about that sooner or later. It's another reason I don't want more than about 400whp. Getting it to the ground becomes a PITA the further out you go.

I think you're projecting a bit here and making my situation out to be much worse than it is man. IDK what to tell you. There are two scenarios with a supercharger. Either you're going with a roots/twin screw and going to roast the tires off the line, or you're going with a centri and you're going to roast them at about 3000rpm. Unless you are running slicks or very sticky drag radials that will wear out in 10000 miles and do burnouts to heat them up, this is just a fact of life with the blower. I don't race the car so I could care less, but I'd be willing to wager my little non-IC Vortech could give some of these 480+ rwhp twin screw guys a run for their money... strictly because the majority of my power actually does make it to the pavement. Just a hunch. The spin I get get between 3-5k RPM isn't pure spin either. Its laced with some traction. Its not like the ass end is floating out, if that makes sense.
400whp is already beyond the threshold of being able to put power to the ground easily. I get the most spin in first, after I'm rolling, if I am heavy into the throttle. If I popped the clutch from a dead stop I can spin it off the line of course. The car is a manual after all. I could spin the tires off the rim in a manual Hyundai Accent by popping the clutch, so that isn't saying much. If I shift smoothly into second and 3rd I get little to no spin, the blower is huffing and puffing by then and the car is hauling ass.
The 3.73s that are going in tomorrow will make all of this much worse I'm sure, but I just don't care. Having the car be torquey and "hairy" is fun to me.

Yeah I know that street tires don't cut it. In fact that can come up pretty quickly. Mishri can't keep his back end from swinging out on him at WOT right now and all he has is UDP,CMDP,CAI/Tune, and 4.10. Street tires, especially the stock ones, are completely inadequate at anything more than stock power levels.
Honestly even with the minor mods I have on my car right now I can sometimes lose traction at high RPMs going through 1st and 2nd gear. It feels like wheel hop because the tires are right on the edge - losing and gaining traction alternately. However if the pavement is nice and warm they don't do this as bad.
I like being able to do a burnout and all from a standing start but the fact is once I get a blower, even a centri, I'm going to get big wide tires on an 18x10 out back and they will be drag radials. I will drive around town on them too and just suck it up and pay the $$ it ends up costing me. I don't want to end up having to feather it at high RPM when I decide to go WOT. Probably going to try the Nitto 555R since they are not uber expensive and might last a bit longer than the MT or the M&H.
Yeah I wanted to stay with 17's, so I had only 3 choices.
This video is the best example I have of a 400rwhp centri and stock tires. You can see that I take off normally in first then after a second or two I just dump the throttle. I hit 2nd fast, but didn't slam it. The new Falkens are somewhat better than this (but they are certainly not touted as a real high performance tire), so you can probably guess from there what a 555 might do for you.
Honestly if my 17x9's weren't curb rashed I would probably just keep them and stick some 275/50/R17 on the back. And be happy. But since they need replacing I'll get the 18s. Better options for tires.
The spydershaft was real popular around here for a while. I'm probably going to get the dynatech even though it's an extra $200 or so. I know someone who has had his on two cars now both lowered and no vibration problems.
Thought I might get some good opinions on this thread..... BUT IT GOT HIJACKED!!!
Sorry, lol.
The Shaftmasters is a nice piece. My shop even commented on it saying it was well-made. I have no vibration on the highway with it. For $425 shipped compared to $650 - $800 for the other shafts I've seen, I have to give it a thumbs up.
