Top speed for a 10 auto or a 6 speed - Page 4

See link and YouTube. Official timing just under 173. It simply runs out of power to over come aero drag, it hits the wind wall... Not sure how others got to 187, maybe... But I paid 2k to run it on the space shuttle landing strip, which is 3 miles long and very smooth.... Stock 1SSLE and my foot was down to the floor... This was in light rain...

This is the ZL1 section, and OP lists a 2018 ZL1 as his ride. Therefore he seemed to be asking about the ZL1 model from my perspective, not any SS models. Stock SS/1LE is not going anywhere near 187. Specifically the A10 ZL1 is the model that can do 187 or more. Even the M6 ZL1 isn't doing 187 in stock form (gearing problem). ZLE M6 (better gearing than base ZL1 but more drag) has been run on the same landing strip that you did, and it only got 178 in the 2.7 mi.

I plan to go here and find out, but the record is 219, so I can't see breaking 200 in my ZLE.

Find out on this thread that a Camaro has a higher top speed than a Chiron according to some. The real top speed however is 198 mph for a non 1le 10 speed Zl1. Any other version is slower.

You're absolutely right about stock Camaros, but some in this thread are modded and have more power to overcome drag. I'm sure my A8 SS can do more than 180 mph now, for example, given it has 735 rwhp as opposed to 390-ish stock.

Yea, that is why I said it was an older post... And if it was 178, the stock SS 1LE did pretty good with a track alignment and in the rain..

The silver state challenge and open Nevada race have several requirements to even get close to sniffing 175+ requires multiple visits and making your car into a race car with roll bar and harnesses along with several other things.

I went and did the 1/2 mile shootout at the SS challenge years ago with a 67 with a BBC and rollbar and thought about going back with my 17 for it and the 1 mile run but the requirements have stiffened up and the 1 mile you have to make a race car out of your street car (same requirements to run over 150 in the SS challenge) so that idea went away.

Having run the Mohave magnum mile (1.5 mile) with a 520 rwhp 04 Z06 at 186mph I was confident my 668 whp ZL1 could crack 200, but due to the airport declining to participate any more a few years ago it's gone away.

The outfit that was running in NC moved to the Midwest and I inquired about doing their 1.25 mile, but I'd need another 100 rwhp there to crack 200 and again, they want a race car to do that, not a street car which leaves the outfit in Fla at the space shuttle landing the only one left that I know of and it's a lotta on the pricey side. Bummer!

What do you know about this one? https://sunvalleytourdeforce.com/

I thought that both events were closer to, "run what you brung." No way am I installing a roll cage to run such events. And bless the NHRA's heart for making their rules a bit more accommodative.

No. You're just misreading and misunderstanding what people are writing. The people you're referring to are talking about maximum speed based on gear ratio, not actual top speed when factoring power and wind issues.

Yep, considering that the ZLE was advertised as going 191, seeing such a long run only reach 178 was underwhelming. Would like to see a normal ZL1 A10 make that run. One of the forum members ran Texas Mile, and he got 173 with a stock A10 ZL1 in just 1.0 mile. Seeing that your SS/1LE gained 17mph from the 1.0 to the 2.7 mark, then the A10 ZL1 should be moving pretty decent on such a run.

Maximum speed based on gear rations where? In a tunnel with zero wind resistance? When talking about a vehicle s top speed the only thing that matters is in the real world. Gear ratio doesnt matter if you dont have the power to reach that hypothetical speed. Useless to even talk about it.

Your opinion is noted. Sorry this discussion is confusing and confounding for you.

Knowing the speed at which a particular vehicle will redline is valuable information. You can then apply that knowledge to the real world. What is your "real world" for the purpose of top speed? Two perfectly measured runs with scientific equipment to come up with a two direction average? A freeway? A runway? A slight downgrade? A tail wind? All of these will affect top speed in a given situation. Knowing the A10 won't redline in the top gear (or likely even the 8th or 9th) at any practically attainable speed is relevant to thinking people. You have discarded that information out of hand as irrelevant to the question of top speed.

I ran over 171 at the Texas mile in 90 degrees with aforementioned Z06. I inquired on the Sun Valley race several months ago and actually can't remember their requirements as they were 2 years out on reservations and I believe they only do a 1 mile gig.

My bucket list was to hit 200 mph in an event and at this point it appears you'd need around 900 whp to do that in a 1 mile event. With my engine in sick bay and my son wanting to crack the 200 mph goal we are kicking it around on what specs to build the engine to.

My choice would be to reuse the current engine with new pistons and rods and a 32% Cam and port the blower, shooting for 750 rwhp and save $10k-$13k from the additional 150hp, which my son favors. Heck, we could pay the $2k entry for the Fla event and add in another $1500 for fuel and hotel to trailer the car there and still be significantly under the cost for the Maggie and all the needed fuel upgrades and end up with a car that can't see that power used on the street or road course. It's already faster then the brakes can manage it on a long straight now!
