Nope never happen on that chassis, plus the ZR-1 is too "smart".
Most newer high powered cars would be totalled with no nannies at all.

Had my car out today. '90 with NO cruise or any nanny stuff and still running the little 275's.

Can verify "most" people with new power levels in our cars will lose it quickly just like the vids on yoututbe of AC cobras getting out of control, or at least make them scared of it even way less power. Seeing the vids of new cars with 700hp-900hp are cool, but put that in an old car WITH original style suspension even new and it will feel insane.


When a c4 gets out of control it does not like it and wants to spin or hook and shoot the other direction. Fox bodies I felt more in control when out of control.

Anyways, OP I think you are on point with this, but I think where you would really get the c4 in to shape is to get real light unsprung components. Even still, unless a prodriver or real risk taker I think you can "comfortably" drive the new car and push the new car much harder, if you did keep up you'd lose 20lbs of sweat from the work and the nerves. I think the c4 is still kind of responsive or "analog" so that experience takes work.

The Callaway was nothing to be compared to. Forget about that car. The price to do that back then was insane just for tires for it.

New= better.

Very easy actually. Buy one of everything for a new ZR1 and assemble.

ASR is junk. Wish there was a way to easily disable it permantly.

I love C4s like nobody else, but reality time... It would take 2 flat tires on the C7 ZR1 for a C4 ZR-1 to be able to beat it.

1/2 the horsepower and none of the refinements. Advantage, C7. Tie marches on. Enjoy your C4 for what it is, and the C7 can never be.

Technology will always win regardless the amount of $$$ tossed into a C4 ZR-1. Pull two wires off the plugs of the C7 and you got this!!😜

A highly modded one wont. ITs more than power vs weight, look at the C7 structure, aero all the electronics. Even if turned off there are still systems that keep that car from killing the owner.
At a point its just not feasible. The C4 chassis is like a wet noodle in comparison.

Only old vs newer comparo but look what he did to do it, lots of resources, this was no garage build. Tons of engineering. He helped me with my T56 conversion in the late 90s.


New cars other than stats are boring but gotta admit under the ugly skin is a bad bitch.
One day they will get rid of those 4 ghey exhaust tips that belong on a 1974 van

This is the best statement of the thread so far. The aftermarket can compete with everything except for the basic chassis. My car, even with the bracing I have done/will do once I put in the X-brace, or even others cars, unless they are fully caged, and engineered for the cage to completely rigidize the body, just don't have a chance.

A C5 with its hydroformed frame would be better to start with.

This is me showing my ignorance, BUT I believe the c4zr1 has the least chance of beating a new one.

I don't know the engine limits, but I have never seen more than 600hp in a c4 zr1.
Does anyone know the block limits?

If the LT5 block can make 1,000+hp I will probably buy on, but I always thought it did not, is that is why I have a stripped down base vert.

You can throw any motor you want in regular c4,

You have close to new power levels, why not keep working on you chassis?
Ton, has been showing some of the weak points on the c4 with his cart build.

Now for me the real question is... can a c5 with mods "actually" compete with a c7? I am fairly positive a c5 unless tube chassis will never.

This thread talks about LT5 performance potential.Notice those comments are almost 5 years ago.

If this is to be believed, this would go a long way by providing the power for a non-ZR1. Then you would need to spend as least as much or more on the chassis, brakes, etc and you still would be driving the flexible flier

You can get C4's up into the same HP realm, but the chassis/brake etc technologies have continued forward and it is hard to catch up

Along with most of the folks on the board. Maybe a quick straight away dash, but nowhere close to the cars limits. That takes talent and seat time.

Just show up and make an official pass, something the new zr1 hasn't done.

pologreen1

Thanks

This is what I figured like 600-700. That takes a lot of cash too.

My motor with higher compression and bigger heads makes 820hp. VS my mild compression smaller heads 700hp. Can take a 500 shot too. LT5 block is well maxed at new zr1 levels.

Aftermarket blocks can make 1800hp twin turbo rather cheap (relative to individual) if a person wants to. The LT5 is the limiter before we even get to the the actual car not being up to the task of being a match for the new car.

It was way more important. Back then there was nothing like it from America.

If you look at Callaway before that was just too far out there for most.

The '09 zr1 was cool based on power levels, but Viper always had the numbers game and NA at that. The vette being supercharged is not too impressive to me especially seeing as how by '09 youtubers were making over 1,000hp on ls motors in vettes at a fraction of the price of the 620? or whatever it was.
