What does it take to get a 90 ZR1 to do 11.5 in the ¼?
I'm guessing with a set of stickies, 4.10 cogs, High Performance Ignition, Cat-Back Exhaust, Air Intake, and a good driver?

I doubt they need the screamin demon coils. Don't forget these babies weight a couple hundred pounds more than the normal C4s. The 4.10s and tires probably would get the car into the very high 11s.
I obviously don't have a clue, but these guys do. :yesnod:

I'm doing 12.6 with a Borla and a K&N. Gears and port work on the injector housings and intake would probably get me damn close.

Hello!
To get a LT5 into the mid 11s, you are going to have to be willing to do a few things: 1) install headers 2)4.10s 3)cat back exhaust, 4)new chip cal, 5)ported plenum and injector housings. The final thing you're going to have to be willing to do is potentially break the driveline *somewhere* leaving the line..
Given the above mods you could run 11.80s-12.0s pretty consistently with a 1.7-1.8 60ft time on stickies. To get to the 11.50s you're going to have to get some 1.5 short times, which is right at the limit of what the u-joints, etc can handle.
One thing you need to understand is LT5s really aren't good quarter mile cars(nomex *on*;)). They don't really start pulling until 3rd gear which is well into the second half of the track. The above mods would put you in the 118-120mph range.

I'm not sure a stock displacement LT5 can do it unless it's on the bottle. A good running 368" w/good driver can run 11.50's,though. JMO.

Hi,
The best times we have on record with a ZR1 with headers, 4.10 rear axle, Chip, free-flow exhaust are 12.2 @ 117mph. This was a 1994 model.
I believe that Clint is right when he said that it would take the bottle to hit this range. The Callaway Supernatural with a 4.10 setup (pushes around 490hp) came in at a best of 12.0 @ 119mph. These numbers were gathered back in 1994 at a local track in cool temperatures.
Clint, a ZR1 with 4.10 rear axle would probably need between 530 to 550hp to break into the mid 11's? Most of the testing we did back then was on stock cars in this area. Only one ZR1 we were going to test with a 200hp NOS kit but the owner decided to use it on the way to the local strip and blew his motor up.
Take care all,
Stan :chevy :seeya

Re: (Ultra Slow)
Sorry to disagree with you guys but for a car to be considered to be the "best all around supercar" as you put it,it has to be a good 1/4 mile performer. It goes with the territory,folks.
Not meant for the dragstrip? Ok,I might can agree with that but please name any car that was built strictly for the strip in the last 15 years? Now,name one car that is highly acclaimed for its performance that doesn't include the strip?
While we're at it,name another car with the same power that dominates the ZR-1? There aren't any that comes readily to mind so why is the ZR-1 considered a poor strip performer?
This ought to be interesting.

Re: (SNKSKNR)
You can set up anything to go fast in the quarter. Why choose a vette? There are many other cars out their that make better quarter milers at a significant cost reduction.

Re: (5.7 Liter)
You didn't answer my question. What car with the same power level is significantly better than a ZR-1 at the strip? Cost wasn't part of the equation.

Clint:
No flame intended but a Porshe Turbo(415hp 10 over a 93 up ZR-1; cost was not in your equation)will run high 11s, stock, off the showroom floor if you are willing to abuse it off the line. Darin D. turned 12.4@115 in his completely stock 911T just driving it off the line. Not many stock ZR-1s are going to do that; a few would.. Now let's talk about the complete package... Face it, if money is no object, myriad cars will beat the ZR-1 in a straight line, on a road course, etc. To quote your sig, The only substitute for Cubic inches, is cubic dollars.. This *definitely* holds true here..

Re: (ZR WON)
Ok,that's one car,Brian. Let's hear of another,someone.
If those myriad cars have more power,that's understandable. Since most of us can't afford a 93-95 ZR-1 or Porsche TT,let's make it more interesting and add cost into the picture. What car with equivalent power will outrun a 90-92 ZR-1 in the 1/4? How many will run 180+mph for the same cost?
Are we having fun yet? :yesnod:

Re: What does it take to get a 90 ZR1 to do 11.5 in the ¼? (TIMSPEED)
Back to the discussion, I think the LT5 would either need nitrous or larger displacement. Most 368's with stock cams and drag radials turn 11.7 to 11.8. The next step up would be a 368 with more aggressive cams. These cars will produce about 450-to 460 rwhp
For each tenth off the quarter mile time it takes significantly more power.
Nitrous of course is a less expensive route. I've seen a relatively stock C5 engine and 225hp nos kit run 10.6. He likely had more nitrous but thats all he would admit.
415s will easily run well below 11.5

Corey H's mild 368" produced 430rwhp on its last dyno trip and has run in the 11.50's w/ET Streets so I would say you're definitely in the ballpark.

Any ZR-1 that can MPH 116 plus will go in the 11's with the right 60 ft.
To go 11.50's it'll take a few more ponies/MPH.

Re: What does it take to get a 90 ZR1 to do 11.5 in the ¼? (ZR1Pete)
5.7 liter is right, the Turbo buick makes a better drag car. it was only rated at 235 HP. Stock, the turbo buick is slower (about a 13.8 - 14.0 quarter @ 101) but relatively low cost mods really wake the car up. the solid 4 link rear makes the car hook well, and it's pretty ez to get a turbo buick in the 11s, 10's cost a bit more. but for all around performance, the buick doesn't hold a candle to the ZR1, I drive both these cars every day and the ZR1 always gets the nod even though the turbo buick is quicker. please no flames, I love BOTH of these cars, but you have to go on what the timeslips read. :cool:
