I was wondering how my LS1 would stack up against the king of the hill? I had the opportunity to drive a '93 last Sunday but it was running a little sick. The owner doesn't take very good care of it. So I'm wondering what kind of stock times you guy's are turning, and if any of you ran an LS1 yet? Thanks! Great cars :cheers:

Don't run one from a 40mph roll.

As amazing as LS1's top ends are, LT5's are just more amazing(in my experience atleast). Not only do they pull a little harder, they pull harder for longer, and keep pulling till near redline in 5th(180 + or - a mph). If you have a chance to run one, run it up to the lowest speed possible. It will be MUCH closer to 100 as opposed to 150. Both badass motors IMO

My old '90 ran 13.1@113.06MPH. That's with massive wheelspin in 1st, slight kick to the right on the 1-2 shift and a chirp in 3rd. I couldn't afford sticky tires at the time <G>. Most ZR1's up here are dyno'ing around 320-330RWHP stock. Mine dyno'd at 340RWHP with headers (and cats).

My '94 would've had another 20RWHP to start off with (they go from 340-360RWHP).

The best answer to your question is to race one or drive one that works (which should be most if they're not ragged out).

I wouldn't try it :nono:

Dave - I assume that you are talking about a Camaro SS or Ram Air. In my opinion there is a huge difference. Even if your talking about a Corvette with a LS1 or even the LT4; the high revving LT5 is awesome! I never ran it at a drag strip, but I've raced friends several times who had a LS1, LT4, Ram Air, and a bunch of other stuff. The Ram Air is little competition, the LT4 falls behind at about 50-60 MPH, the LS1 Corvettes seem to hang better to about 70-80 MPH, but then the ZR1 seems to pull away. Taking into consideration that these cars are pretty much stock except for minor enhancements like exhaust, chip, air box. I also have a Z06, but havent really raced the ZR1 against it. I'm waiting because I need new tires on the ZR1; and I did try to race against my wife once; she pulled ahead quickly at launch as I sat spinning the tires. The Z06 is great, but I really love the ZR1. ZR1 dyno'd @357rwhp.

Dave@808

Pretty much what I expected. I know the LT5 is one hell of a motor. The ZR1's I saw running here in Hawaii were cranking out mid to low 13's which is right where I should be at. I can't recall what the LT5's were trapping though....hmmm. Would be fun just to run against one for the hell of it. Thanks for the input boys!

your only giving up about 20-30 horsepower to the tires. A few mods and you would be right there. remember c5's weigh less than c4's.

If he can't drive it all that well, I say go for it. :reddevil

Quarter mile, like who cares, but SS Camaros on a road course are nothing to be sneezed at. I had to severely hustle in a Z06 to keep up with an instructor-driven SS at Bragg-Smith last fall, which taught me to never overestimate myself or underestimate the car in front.... he was getting some inside-rear-wheel lock-up on corner entry but I was unable to do anything about it in an arguably better car. In that situation, if the Z06 could not do anything about it my hands, then my ZR1 could not either.

Bragging rights often belong to the driver, regardless of car specs.

Drat.

Dave,
What few bolt-ons do you have? Is your SS a 6-speed or A4? Like they said, couple more bolt-ons, you shouldnt be far behind at all. :nonod: :smash: :chevy :seeya

If you are good and you have some sticky tires, you can out tire it as the ZO6 does, but you'll never outpower it on the big end even with a 150 shot. Just put some sticky tires on the ZR1 and its a great 1320 ftr, but it shines in world class performance and world class is not 1320 feet.

Dave@808

LT1pwrd'94, I got an FTRA,lid,Corsa cat-back,all suspension bracing pieces,Pro 5.0 and a ported MAF. I ran with a C5 when I first test drove the SS and it was door to door all the way through 3rd from a dead stop. :D The salesman almost pinched a loaf in his pants I think LOL.

I have tremendous respect for the ZR1 but I am very interested to see how it pulls on a top end car like the new LS1 cars. :boxing I think it would be a battle!

Ultra Slow

I would be be glad to show you. Its too bad you are in hawaii. I dont know the roads there in hawaii, but I would imagine you do not have the roads to allow these ZR1s to get up to 190 MPH as we do here and a short race to 80 or 100 is not going to tell the story, just tell who started first or has better tires and ripped more syncros up and was more willing to beat the hell out of their car. I know your car is capable of high 12's with drag radials, but its not going to do what a ZR1 does. There is a difference in 1/4 mile racing and world class performance, the ZR1 is world class performance. I personally race all the time, see 180+ MPH many times a month. The ZR1 will put literally 1/4 mile distance on an LS1 6 speed corvette and even more on your big F body on a top speed run. You can modify the LS1 and get closer, but its going to take going into the motor and stroking it to do what a ZR1 does and you still will not have its reliability and then far less with yours modified and its still not a ZR1. The ZO6 gets left pretty hard too after 100. Many bus lengths and they of course are done before 170 and the ZR1 is going to and even past 190. We have not seen the new zo6 run yet, so that is next but its not a top ender either. The only comment I ever hear racing people that want to challange the ZR1 is the same one... "I did not know those cars were so fast" .. "Are you running nitros because I was". We are not talking about 1/4 mile stuff as many cars between 300-450 HP are close in ets in the 1/4 mile with just tire changes and even gears. Open these cars up on a real road where you are redlining 5th and even going into 6th is where the real difference comes into play. You will gain a new perspective of the ZR1. If racing 6 or 7 miles at speeds of 180+ is insane to you, the LS1 or zo6 will suit you fine as this is what the ZR1 does and why it retains the name "king of the hill".

Dave@808

Thanks for the offer Ultra Slow but I think I gotta run someone from Hawaii.;) Texas? It'd cost waaayyyy too much to race you. BTW, I'm pretty sure with a better launch pad I could break 12's. That is right where the ZR1 was originally, I thought. Right now I've run a best of 13.21@107.8mph (I know I gotta change the sig) and this was with a 2.39 60' time (my F1's are balding). I figure with ideal traction I'd be pretty close to a ZR1 in a 1/4.

Now on the street maybe upto 150 or something that might be all different, I don't know how long it takes either car to get to that speed. I just can't see the ZR1 being that much faster than todays C5's and Fbods. Maybe one of these days I'll find out........

Dave@808

Hey man you modified the post, now my reply is all screwed:D I was reading your edited reply and I'm thinking how many times do most people have the opportunity to go the speeds you're talking about? I'm thinking how will my LS1 stand against the ZR1 in a somewhat more sane scenario, maybe something like 0-120mph or something. 190:eek:? I don't think there's anyplace safe in Honolulu to reach those kinds of speeds (even if the car was capable of it).

Ultra Slow

Yes, thats what the ZR1 does. If you want to take a ZR1 and tire and gear it and lose some of its built in high speed, then you have a low 12 car at 117+ MPH. Its going to be tough to build a ZR1 out of an f body... I tried. I have a bowtie 406CID, DNE 6 speed, dana 44 rear end 3rd gen car, you can see it in my pics. #21. It more the less has a 406 CID nascar style 12:1 roller motor in it. It weighs 3500LBS. I have been working with it since 1983. I have over 60K in the car, I will be burried in it when I die, and its a far far cry from a ZR1 even though it can beat one to 120 as it has 550HP, but the sacrifices were by no means worth it and the ZR1 is still faster where it counts. I have learned tons from my f body and its only got 15,000 miles on a mint condition rare daytona/recaro TA, 1 of 200 and it is really a neat car. I would trade it for an average high mile ZR1 in a heartbeat.

Well said UltraSlow. I enjoy your posts. You have a good way with words.
I can also vouch for the topend. I had the chance to race a 3rd Gen RX-7 TT a few nites ago from a 40 punch. When I hit about 140ish, it was literally bus lengths (atleast 15) (30 friends can vouch for this), and it was getting so much worse the higher we went. I agree that LS1's have very good top ends if your talking about running a little over 100, but they absolutely do not compare and shouldn't be put in the same category as a ZR-1 on REAL top end. They cost $60-70 grand for a reason, and its not b/c of its 1/4 times and traps.

Yes, the king would be quite confined on that island, kind of like being exiled.

Ultra Slow

Thanks,

Yes the RX7 is a fun kill, especially when the guy goes through a half a dozen motors to do it as one did that tried to beat one of my ZR1's many years back before all ther RX7s got blown up. He actually got the car up to 450 RWHP at 26PSI. He beat me once to 130 but blew it and scattered most of it on the road, that was the end of that car and have not heard from him since. Just trying to push too much from too little.... This seems to be the thing with alot of these cars.
