Faster for 1991, ZR-1 or SY

What was faster in 1991 was it the ZR-1 or the Syclone. I'm sure that if I ask here it will be the Sy and if I ask in the vette forums it will be the ZR-1. I really would love to get to the bottom of this though. 0-60, 1/8th, and 1/4.

Re: Faster for 1991, ZR-1 or SY

Some of the fatest times in a stock Syclone have been 13.1s-13.3s between 99-104mph during magazine testing.

0-60 times range from 4.6-4.9 (in the rain)

Most of them came from the factory doing 0-60 in 4.3 secs, but they under rated them....at least thats what the engineers I have spoken with said.

Re: Faster for 1991, ZR-1 or SY

I remember when the Syclone's came out, and do remember that they posted quicker 1/4 mile times than the standard Vette, but the ZR-1 was faster.....not by much, and probably with a pro driver too.

At least that's the way I remember it.

zr1 are made for top end not off the line. i would still say pretty close. at the gmhtp mag show a couple weeks ago the zr1 wsas in the 14-15s all day till the last couple passes and made a few mid-high 13s. this was his first time racing it but i can not see it getting much better then a 13.2-4

The ZR1 would be a good race in the 1/4. but a Sy should take it on the 0-60 and 1/8.

if thats your opinion, they why the **** did you bother asking the question?

thinking of questions, you do know this forum has a search feature right?? how many ****ing questions can you ask in 24 hours, because heres some free advice, THEY HAVE ALL BEEN ASKED BEFORE! :roll:

Before you ask another question on here, try clicking here: http://www.syty.net/forums/search.php?

but like everyone said, the Sy has the 0-60 and the 1/8th.

1/4 Mile went to the ZR1 by a few tenths and the top speed definately went to the Vette.

ZR-1 are hard to drive. A well driven stock Zr-1 can break into high 12's with a good driver.

Anyways 0-60mph they post similar times, but the Sy is way ahead (distance wise) of the Zr-1. My best friend has a stock Zr-1 and we have compared timeslips. A stock properly running Sy will win 60', 330' 1/8 and 1000' ET's. On a good run the Zr-1 will win 1/4 mile. Having said that, if my friend raced his Zr1 at the track vs a Sy, he would probably only win 15-20% of the time due his difficultly consisitently launch his Zr-1.

On night we were trying to figure out how to launch his Zr-1 (on street tires, the owners on the Zr-1 say use Drag Radials) We praticed trying to get a good launch it either spun or bigged. He tried a bunch of time and let me have a crack at it. I consider myself a very good standard driver, and I had a hard time drag launching his car with out spinning or bogging.

Re: Faster for 1991, ZR-1 or SY

I know the 90 still had the 375 horse motor and I'm pretty sure it din't change to 405 until 92. The fastest I've ever seen a stock 375 horse Zr1 run in a magazine was 13.4, at the track with optimal conditions. I have witnessed a stock 90 on slicks get into the 13.0's with one of the best drivers I've ever met.

The 405 horse Zr1's in magazine testing ran a 13.2. I haven't seen one run that personally, but have heard quite a few accounts of breaking into the 12.9 area with good drivers at the track on street tires.

Either way, a well running Syclone with a good launch should easily be able to handle them up to a quarter mile on the street. After that, the Zr1 will hit the area it was designed for, and fly by on the top end like bullet. On the track with an average driver, the Syclone would probably have a very small edge over the Zr1. With a good driver, I'd flip a coin. On the average street, in completely stock form the Zr1 is done.

The 405 hp motor change was in 1993. (of that hp gain, 15 hp was gained through a free flowing exhuast) The 90-92 375 hp models varied from about 365hp to 395hp on dyno and the 405 hp seem to dyno in the 400hp to 415hp range. Most of the stronger 375 rated motor were 90's but that doesn't mean all of the 90's are.

My friend ZR-1 did 334rwhp (~392 crank hp) and is 100% bone stock down to the air filter. On 7 year old Michelins Pilots, he ran 12.9@113mph, with only a 2.1 60'. It took him 5 trips to the track and few side street practice sessions to better his 13.3 @ 110mph (which was his first run ever with no practice). What funny about my friend ZR-1 is you can tell how well he does by his trap speed. 106-7mphs launched too low or completely spun bogged when it caught and runs 13.6-13.9; 110 mph launched too high runs 13.3-13.5; 113mph equals 12.9-13.1.

Their is Corvette guru at my local track who is a great Corvette drag racer (alway turns amazing times for the vehicle), he ran a 12.7@114 in a stock ZR-1.

He's not a good racer, he's an artist. :eek: :lol:

This same question was posed on a Corvette board, and it seemed from some participants that the discussion was going on across a few. I thought it would be interesting to search around for other perspectives and opinions, and I was also interested to hear from other GMHTP shootout participants as the event was a lot of fun.

Anyway, the three videos I have of my runs are all 13.5 and lower:

http://members.aol.com/corvettezr11990/gmhtp/clips/zr11.mpg
http://members.aol.com/corvettezr11990/gmhtp/clips/zr12.mpg
http://members.aol.com/corvettezr11990/gmhtp/clips/zr13.mpg

The way they gave feedback on runs (or, rather, didn't give you any feedback at all) was idiotic, so it's hard to say what everyone ran each time. But, I never to my knowledge ran in the 15's, and the one run in the 14's was because I way overcooked the launch, and decided to just stay on it for fun. I could always make another run.

While I'd certainly expect any discussion of the event from a certain type of owners would be biased towards that type of car, there's no reason to be mean about it. :p

As an aside, I believe the magazine should be out around the very end of September. I found a local bookstore that carries it and pumped them for info about when they typically get delivery of new magazines. :)

I think I've at least one video of a Typhoon going down the track, I'll dig it up and post it. I'd also love to hear from anyone with better videos of me going down the track. :cheers:

92 Typhoon: Bone stock
Re: Faster for 1991, ZR-1 or SY

I owned a 91 ZR1, bought it in early 92(a left over). The first time I took it to Brandenton, FL I could only get a 13.5 (can't remember the mph) My 60 foot time was like 2.2, 2.1 maybe. Came back to Ft. Myers and talked with some of my racing buds and one of the GN guys said to try to tach it up to about 5000rpms and slip the clutch. Made since because the thing didn't wake up until you got over 4 grand. Take it back to the track and my first run was 13.0 at like 107. Best of the day was 12.8 at 109mph. Best ever was a 12.6 bone stock(they didn't have any mods for it then and I could'nt afford them anyway with the price of the ZR1). I have a 92 Typhoon now and love the thing. It's still stock with 33,000 but will soon see some mods. The Syclone would put 3 out of the hole but the ZR1 launched right would drive by in a big way. Most guys didn't race there ZR1's the way I did and would probly blow a shift when the Syclone smoked em at the light. I've owned both and each awesome in their own right. Now a modded Syclone is another story. Dollar for dollar the little truck would wipe the smirk off the Vette owner face. Don't get me wrong, that Vette was the best car I've ever owned so don't think I'm haten' on the ZR1 guys.

Re: Faster for 1991, ZR-1 or SY

We have a Corvette center here in the Springs. Since I owned a Vette, I developed a relationship with the owner who would give me pointers abotu my car. One day we talked abotu ZR1's as he had 2 of them in his showroom. Next to them was a Z06. I asked him which car is faster and he told me they were very comparible in acceleration and top end. Handling obviously the Z06 owns. This is a guy who was very experienced at racing Corvettes of all kinds. He also happens to be a SYTY guy. He told me that they raced his SY against the ZR1 and and the SY took him most of the way but the ZR1 pulled past runnign a low 13 all the way up here @ 6000ft. Thats about what hte stock Z06's are running up here in the clouds. I always wnated a ZR1, I think htey have the most "originaly" motor out of any GM product ever made. Z06's are nice as hell and I would love to have one but i cant stand knowing that my motor would be iin like 4 other cars.

Re: Faster for 1991, ZR-1 or SY

I don't have the slip handy, but my '95 ZR-1 ran a best of 12.63@113 with a 1.94 60ft in bone stock form, including the tires (Goodyear GSCs).

Anybody that says a ZR-1 is hard to launch is 100% correct. The car with stock gearing is capable of 60MPH in 1st gear and can do almost 116 (or was it 118) in third gear before hitting the limiter. I had the 405HP engine, but I don't think the 375HP motor was much slower, if it was in fact slower.
