lt-4 vs. Zr-1 or Z06

[novafink]

Has anyone seen a drag between the a lt-4 and a Zr-1 or Z06, I am assuming a stock lt-4 woud loose the battle, but curious how badly. This thread should lead to some interesting responses, thanks

I guess it would depend on what year the ZR-1 is. The '90-'93 ZR-1's had 375 hp, I believe, where the '94,'95's had 405hp. I'd guess that a '94 or '95 ZR-1 would give the Z06 a go, but I don't see the LT-4 sticking with either one. This is of course taking into consideration that these cars are completely stock....no mods.
This is just my opinion, and I have been known to be wrong before!

Actually I think you are right about the LT4. As to how badly it would lose I really don't know. Some others would have to answer that and I would be interested to see what they say. But, I am sure I speak for all LT4 owners when I say I am honoured just to be mentioned in the same sentence as a ZR-1 and a Z06.

LT4's can nip at the heels of ZR1's, but the Z's will win out because of the higher revving engine. anytime you have 2 engines with even equal power, but one has a wider power-band, the wider power band gives an up... especially for high speed stuff, say 80 MPH up. The flat torque curve of the LT4 further helps to give it an edge on the low-end to stay close to the ZR1.

The Z06 is another animal, I haven't seen LT4 Vs. Z06 before... anyone out there that has?

 

[DRTH VTR]

I run an essentially stock Z06 that runs mid 12's at 2600' elevation. The few LT4's that I have seen run mid 13's and the ZR1's run in between. I know that I beat the one ZR1 that I lined up against by about 0.4-0.5 seconds. That is just my experience at my local track, so take it for what it is worth.

The 405 HP LT5 came out in 93. I agree with the rest of what you said except the LT4 engine will probably hang closer than most woulfd expect. That was a nice revving engine and had plenty of low RPM TQ to get it all moving. Unfortunately, it was wrapped in a 3500 lb car.

It's starting to look like on the street we need to factor in driver skill, I suppose a lt-4 with a good driver could run with a bad zr-1 or z-06 driver, put a good driver in the later and it looks like its all over for the lt-4

At test and tune:
Owner of a new Z06 had returned from Bowling Green to Ohio, he had ordered the museum delivery. With just over 500 miles on the Z, this was his first run down the 1/4. He clocked off a 12.6 @ 113. Not to shabby for a first run. I can’t remember exactly what I ran that night, but it was probably in the mid 13’s. My best run with my LT4 is 13.3 @ 107. No way in Hades could I keep up with a Z06, or a ZR-1 for that matter -- unless those drivers made a huge error. I’ve never seen a ZR-1 at the track, Z06’s are plentiful, usually run mid 12’s at 115+.

I did have a ZR-1 experience where I was in my car and I was trying to merge. A red C4 slowed down to let me in, as traffic became less saturated, the red C4 leaped to the left lane and was right along side me, she beat me to the wave and then rocketed past me. As she pulled away, I saw that it was a ZR-1!!!!!! Wooooo Hooooooo!!!!!!!

I saw two amazing things that night during my commute home: The blond driving was very easy on the eyes. Second, a ZR-1 moves out like a scaled cat. I got to see and hear a ZR-1 take off up close and personal! I can only imagine what it must be like in the drivers seat. You lucky sons-of guns! :cry

LT4 may have been an option bargain at the time...even now.

Enjoyed that story you related B17Crew. And Yeah, I also really think the ZR-1 and the Z06 have a bit too much for the LT4 and they both are amazing cars.

But, when you compare the performance differences, the LT4 in 1996 at about a $1600 option was a bargain when you think of the upgrade price for a ZR-1 or a Z06. Ok, sure, with the ZR-1 and the Z06 there was more to the package than just the engine, but man, the ZR-1 was about $25,000 more than the coupe and a Z06 $6000 more (I could be off on these figure as my Black Book is not with me ) so the LT4 was a pretty reasonable option and as there are not too many around I've read on this forum that they command about $2000 more in the market. When you look at your run of 13.3 at 107mph that's a pretty good deal still. By the way, nice run.

B17,

That just means that you'll have to start modding.

Watching our weight through the holidays!

True vettepilot. By the way, the Black Book shows the coupe weight in 1996 at 3298 pounds. Not that that is a big difference from 3500 lbs, but the 1996 coupe I think then is about 80 pounds heavier than your Z06...which is not a huge difference and maybe that is one reason why it does hang only a little back but as you say closer than you would expect. I agree with the other reason of plenty of low RPM Torque. I am not sure if the black book weight is for the coupe with the LT1 or LT4, but maybe they weigh the same, though the LT1 is auto and the LT4 is with the 6 speed and that could make a difference.

Roadster Guy,
I totally agree, with you. ZR-1s were at a much higher price point, when new, they were well without of my reach.

I’ll always have a soft spot in my heart for the ZR-1. I remember when it was introduced and how I read everything I could on them. Seeing one in person for the first time was even more memorable. I’m plenty happy with my LT4, it has turned out to be a nice car to have in the stable. To this day, after almost 10 years, my dream car is still a 1995 Competition Yellow ZR-1 (Santa, can you hear me now)!

Took a lot of practice to hit 13.3. The track never seems the same after each consecutive visit.

That just means that you'll have to start modding.

Got to admit, it’s tempting...

From what I have seen on tracks, on the dyno and in different mags :

Typical LT4's can run 13.2 @ 108

for ZR-1's its tough because they vary alot more and were produced with two hp ratings but typically can run 12.8-9 @ 111-112

01 Z06's typically can go 12.7@113+ and 02-04's 12.5@115+

These are for decent drivers on a decent track with decent conditions. I have seen many much quicker 12.8's@almost110 for stock LT4 or 11.98@almost 118 for 04 Z06.....

Lt4 coupes typicall weigh 3300-3350+, ZR-1's 3400-3500 , and Z06's 3125 or so all gassed up .

LT4's will dyno 290-300, early ZR-1's ~325+, late ZR-1's~350ish, 01 Z06's 330-340+, 02+ Z06's 350-360+

Oh , my heads cam LT4 has gone 12.0 @ 118 , would be faster with better conditions.

Hope that helps....

That's very strong Shriker, congrats! I've only been to the strip once in my Z since the build up, and I was pretty disappointed. It was at Beach Bend last July in BG at the Z06 Fest. The track was like an ice rink, and I just couldn't put the power to the pavement. The best I could do was an 11.80 @ 126mph. I'm pretty sure I'll get it into the 10's this spring once I get my DR's broken in.

 

[Edmond]

Leave it up to a Z06 guy to be disappointed in running 11.8:L:L:L

It's all relative my man, all relative. (Hey, this little guy looks like me trying to get off the line!) :L

 

[Shriker]

Tom , with 600 rwhp , yikes! Yeah I would think with traction you should be good for quite a bit more than high 11's @ 126......that trap speed would indicate ~470 rwhp given what I would guess your car would weigh gassed up (3200 ish). With 130 more rwhp you should see high 130 mph trap speeds in good conditions.

Good luck......sounds like quite an awesome ride, practice , practice!!

 

[Edmond]

It's all relative my man, all relative. (Hey, this little guy looks like me trying to get off the line!) :L

You're just like my neighbor. He has this need for more and more horsepower. The weakest engine he has in his garage is a Z06 engine.:L And he's gathered a lot of literature looking to supercharge it!

He has 4 or 5 motors in his garage ranging from 400 to 900 horsepower. Some of the carbs he has for those motors seem to be bigger than my whole intake manifold.:L
