Curious about 1/8th or 1/4 times for the SC ZO6s...don't see many times posted in signatures and have only matched up at track with a couple of SC Zs or Coupes...always second quessing myself if H/C is faster than SC...just curious.

No numbers from me... yet. I bolted on a set of drag radials and found out that my stock clutch wouldn't hold with the add'l power. I'm in the midst of an upgrade now, hopefully hitting the track in the next few weeks.
H/C cars seem to post better numbers from what I've seen
thats what i am trying to understand, commonly SC cars have more HP and lots more TQ but 1/8th and 1/4 times are a little less (?)....I know if i went to ET streets and had the financial stability to launch at 6000rpm and on the "right day" i could get 10.9s at 128mph. Are the SC drivers like me and more conservative in tires and launches or is there another reason???
Yes, I believe you are correct. People who seem to buy supercharges are lokking for fast street cars. They are not running around with 410's and sum crazy cam. A different mind set.
I DON'T believe this Head/Cam better than Supercharger crap.
Look how the FORD GT destroys the Viper, and the new supercharged Mercedes (617 HP) does 0-60 in 3.8 seconds. These times are on street tires with street gearing.
I've researched this topic in great detail, and that is a pretty easily conclusion to come to.
It's all about average useable HP available under the curve. The Ford GT and Mercedes (while true) is not a great example b/c they use positive displacement blowers which mean instant TQ and outstanding power for the entire racing rev-range.
Going "quick" is all about torque multiplication along with HP, which means a car's gearing is important too.
Forget _peak_ #s. They tell a small fraction of the story. In theory, one type of driver may be more conservative (I am) than others, however. You may be on to something there.
Having competitively raced a centrifugally blown car (the make doesn't matter) for over a decade, I know the nuances about them. And again, the simplest answer I can give is that peak HP/TQ #s do not tell the entire story on how a car will perform at the track. Making peak HP at redline (or your shift point) means nothing, except for a # to post and/or brag about. One hint to new centrifugally SC'd owners... do NOT short-shift even ONE gear, or you will not come close to your potential #s.
But driven properly (and this is where the "conservative driver" theory comes in) and hard...there's nothing holding an SC car back.

Yep. I realize that and should have clarified what I was referring to. This topic has been discussed here several times before, and most often the most "disappointing" (if you can call them that) track times given XXX HP levels are with the centrifugal SCs. This doesn't mean they are bad, of course. I just think quite often people think b/c Car 1 with 525 peak RWHP will automatically outrun Car 2 with 475 peak RWHP, and that is just not the case.
The Magnuson (which is an Eaton blower, same company that manufactures the OEM blowers for the SVT Lightning, SVT Cobra, Ford GT, Pontiac GTP, etc) should perform very well.
The popular centrifugals do, too. I have installed and tuned more Vortech blowers than I can count. They run superbly. I also know they like rpm, so shift 'em out there as high as you safely can for best track results.
thanks guys for the great replies...my H/C car requires considerable tuning attention to keep "happy" and since it is also my daily driver i have to keep it happy.... I struggle with SC or H/C for my next vette ... once you add 100rwhp lots of other components have to be upgraded just to hold the added power especially if racing ... how are your SC cars for maintenance...tuning and the car holding together in general...i mean do they require much on-going attention?
No more attention than a stock motor, IMO. A blower can complicate maintenance for simple items like the accessory belt or alternator. My Vortech Charge Air Cooler is right in front of the alternator. For that reason, it takes me about 25 minutes to remove the alternator vs. about 5 minutes on a stock car.
Other than a chirping pulley (still need to call Vortech), my setup has been trouble free. The added power was too much for my stock clutch, so I'm upgrading it.
Wes has some great points. My car makes peak HP at the limiter. I could probably make 570-575rwhp if I just upped the rev limiter a few 100 rpm. The curve is pointing straight up when I let off the gas on the dyno. Overall I'm happy with my choice of a blower on my car. It drives just like stock when I'm not boosting and the power is great when I stand on it
everyone keeping their numbers a secret? that is what he is asking for is it not?
....nope not asking about "secret" ... the fact that many SC folks don't post numbers probably means they don't have numbers to post (?) ...so i am thinking many or most who do SC it is for overall street quality...so my question is; was that assumption correct (?) and are you happy with overall street performance, maintenance, tuning , reliability etc ... I was happy with my H/C for performance but maintenence and tuning and street manners isn't that desiable for a daily driver and i had very good tuning!
I'll point out again that Optic has posted time slips and shown vids of 9 sec passes. FRC Tom has posted an 11.3 pass and I have been in the very low 10's but I will not post a time slip until I reach the 9's. I'm not sure what else is being asked??
i have ran 11:60@128mph no power shifts, lanching at idle, 2.0 60 footers taking care of my car, in the hot miami weather , still get 24 mpg on the highway
very fun street car .
