I've been to 138mph in the Camaro, it handled great and didn't notice any 'floating'; it actually felt very stable and didn't really feel like you were going that fast.

Back in 1990 I worked at a Nissan dealer. A Nissan engineer visited to show us some new tech, he mentioned the Infinity Q45 could do 162mph with the radio off. I asked ‘what does the radio have to do with it?’ He said the power antenna is worth 1mph. Sent from my iPhone using Tapatalk

Call me a wuss, but I haven't been over or close to 130 (except in an aircraft) since 1965 in a '64 GTO. Just missed hitting a cow at that speed--and had 5 others in the car with me. Yes, I was a stupid teenager showing off for friends--but almost killed them and me! Any more, only in controlled conditions.

I like how after it happened it was spun as Hennessy being "contracted" to test the cameras since the rumor as it was going down was that Hennessy suckered the authority into allowing them to run in exchange of them being able to test the cameras capabilities; same result but totally different means.
I was asking myself this exact question as i was showering the other day, whether or not an otherwise stock SS would be capable of exceeding 200MPH given NOS or some other power adder was used in conjunction to better tires and enough room to stop. Once in a closed road my car was taken up to 137mph by a professional driver and i hear it felt as if it was on ice at that point, that action should not be attempted by amateurs on public roads; any resemblance to real actions is purely concidental and in no way based on true events. |

ZL1 Aerodynamics overview There is more on aero but I don't have it at my fingertips. The different parts on the ZL1 vs SS were not only for cosmetics. I was surprised how much functional design work went into it for being only a submodel of a car. https://media.gm.com/media/us/en/chevrolet/vehicles/camaro-zl1/2012.detail.html/content/Pages/news/us/en/2011/Nov/1101_zl1_aero.html A few more sentences on the topic Last edited by silversleeper; 08-21-2019 at 10:13 PM. |

I'm sure most on here are on Facebook, follow Big Red Camaro. RJ, the owner/driver is actually heading to Maryland to do a 1.5 mile race, which is a 'see how fast you can go' race. I know there's other in Nevada, SoCal, but since you're in New England i'd mention the one in Maryland.

I’ve been over 225 mph, establishing a world record for the 5th Gen Camaro at the time. My car is very stable aerodynamically speaking, now power stability is another subject... I’ve spun the tires pretty much 1st through 5th exceeding 200 mph and still fighting the wheel. It’s not the point and shoot run so many think it is. Sideways and spinning at 200 will pull the little guys tight up into your gut... you just gotta make a decision, stick with it or go find something else to do... Any car is susceptible to lift at given speeds... even those with tons of downforce... watch road course races with most any type of car, and sooner or later all of them will take flight if driven hard enough... bumpy air from other cars, a broken wing, a bounce, hitting another car with open wheels etc...

 I grew my cage to match my capabilities... I could duplicate my car for a hella lot less money than I’ve spent... we were a test bed, and several world record holders have benefitted from lessons we learned... including the current 5th Gen record holder... Quote:
I would like to point out, this is not a drag race... it is not a prepped track, and at least in the events I run they do not allow slicks, skinnies, drag radials or the like. You run a DOT approved (stamped) tire and most of the big power cars run a Hoosier Road Racing tire... they suck (read my previous comment about spinning at 200 +) but they are the best tire available. Most cars run a high end Ultra Sport type tire... and for the record, before anyone bashes them, I’ve been over 200 in a standing Mile on GoodYear Eagle F1 Supercar G2 tires... yup, factory rubber on a 20 inch wheel. Quote:
Let’s discuss acceleration over time... Yes, the Texas Mile and like events are not timed, so to speak but time is an issue. 60 mph, a mile a minute... 120 mph, a mile in 30 seconds... 180 mph, a mile in 20 seconds... 240 mph, is a mile in 15 seconds... I cover the last 1/4 mile in about or just under 4 seconds... How much does any car accelerate in top gear at 220-230-240 mph in 4 seconds.. There is an exponential increase in power needed for each 0.1 mph at a given speed, and the faster you go, the worse it gets... If none of that has blown your mind, a good friend of mine, Mark Heideker just surpassed 300 mph in a standing Mile in a Ford GT... the car was about 230 mph at the half mile, so in less than 6 seconds, they accelerated another 70 mph in the back half... I don’t have the exact numbers, but someone good at math can determine the time needed to cover a half mile while accelerating from 230 - 300 mph... it is mind boggling and I’ve been fast enough to set and hold a record for a while... I’m in awe of his accomplishment... Back to the first sentence of the previous paragraph... if I pass a top fuel car, at the 3/4 mile mark doing 200~~ mph, still accelerating, and they launch on a decent pass, I lose the run to the mile...

I’m a smartarse so please forgive me. The 5th Gen SS will not achieve 170 without tuning work, to at least remove (increase) the speed governor. Mine is set at 355 mph, as opposed to being turned off... I can’t reach the aforementioned speed due to gearing limitations, and possibly the exponential increase in resistance to moving through air... as well as rolling resistance... my car would theoretically achieve 300 mph at the red line in 5th gear.. it has the power, but it would take at least two or maybe a bit more miles to do so... at least with my current transmission it would... With a PPG I could hit it in less than two miles if the car stayed together and on the ground... Quote:
Quote:
I removed the dovetail primarily because no one at GM ever stepped up the say it would not break off at speeds over 200. It was designed for a car computer limited to 155 mph. I didn’t want to be the guy going down track, 200 mph, spoiler snaps off and 1500 or more lbs of downforce suddenly and completely, or even unevenly if one quarter blade broke off since it’s a three piece, and have the ass end suddenly lift off the ground as the suspension unloads... nope, don’t wanna be that guy... Quote:
Quote:
And I have to ask, professional driver of what, a truck. If it felt as if it was on ice at 137, check the tires aand alignment, then find another driver, maybe an amateur like me, or number of guys I race with... beyond that, correct, these cars nor any car should be at 137 on public streets, or most “closed” toads... Quote:
I think the “Maryland” event you mention may be the Loring Landspeed, in Limestone Maine, at the old Loring USAF, SAC base... like the Mohave Magnum, you can run the mile track and shut down at the half or run the full mile, or you can run 1.5 miles on the long track... A couple of quick tricks to “help” reduce front end lift... A vented hood is helpful, though it depends on where the vents are located and how they are designed... too far forward and they are in the high pressure zone at the front of the brick... car, actually potentially forcing more air under the hood.... too far back on the hood and they sit in the high pressure area formed at the base of the windshield, with the same results. Remove the rubber weather stripping at the top of the fire wall... this will allow a metric crap ton (scientific terminology in the racing world) air to escape from under the hood. In the process, it reduces the high pressure area that builds at the base of the windshield and most of the hood bounce in the process. Some, not all, of the hood bounce is possibly from the rubber weather stripping allowing pressure to build up until it burps past the weather stripping, whereupon the hood would seat back down to repeat the process... so why does GM install it... it keeps road grime and crap from coming out from under the hood to light upon your windscreen. Think about the billboard your car is pushing through the air as you increase speed. Most call it a firewall... tomato tomatoe... it’s a wall... Limit the air hitting it by limiting the air allowed in through the grill, both upper and lower grill... tape it off, use plastic inserts and tape those... Have a friend with a ZL1 come over and offer him some beer. Remove his belly pan, Trace it on a sheet of 1/16th of so aluminum plate, cut it out and use Riv-nuts and form it to your front cradle... some gentle persuasion with a mallet or brass hammer and it’ll fit like your buddies, and help settle the front end... Install a for real splitter, not this plastic crap held on by two sided foam tape BS used for shine & show cars that never see the road, much less a track... Don’t be afraid to alter the cosmetics for performance.. there are few fast show cars, and fewer still showy fast cars... I call mine a 25 footer at best... it looks great from 25 feet but any closer, well, it’s a danged race car... Remove the mirrors for high speed passes... above say 170... it does help... As 1911 said, hold your hand out the window at 170 and you’ll find out roughly how much resistance there is... Tape the front end but don’t waste effort on the trunk lid or back glass or things like that... tape on front serves multiple purposes, limiting air under the hood, and it keeps the front fascia/bumper cover from breaking off at speed.. bad form in most cases.. it happened to Lingenfelters 2010 on a drag strip at about 165 mph... Don’t put a lot of thought into spoilers for passes up to say 225.. run the lip spoiler. It will have almost no effect on the car, good or bad... At speeds above say 130, the separation boundary is way above the trunk lid and without a wing (think ZL1 1LE) then the spoiler is doing nothing. It’s a cosmetic passenger... If you want a spoiler that works, you have to either raise it (wing) or move it back, way back, like further back than a pro stock car. They have slicker bodies and improved separation boundaries... you can improve the potential by running vortex generators but without a wind tunnels for testing, you are making a WAG at best... if you are a for real engineer, then you are making an educated WAG... If you opt to move it back, say at least a foot behind the spoiler lid, further if you are going faster, then add high or low strakes. These help realign the aim of the car if you get sideways... I apologize for the novel but figured one big first and then I can attack specific questions as they arise. And no, I’m not an expert, but there is a 1.5 mile long stretch of track in South Texas with a trail of broken parts and lots of lessons learned.. I broke about as many parts as most anyone... Last point.. if you get into “land speed” racing, be wary... it’s addicting, and dammit expensive to go fast... you can quickly end up with a garage weight in the form of a busted car and a pissed off spouse, or no ride to work... have fun hot lapping a relatively stock Camaro at the mile, or prepare to write lots of checks... I’ve worn out several debit cards... I’ll use myself as an example, I built an 800 RWHP rocket for 30k. To add 1200 + more RWHP took well into 6 figures... and at that power, you break often... and nothing small or insignificant ever breaks... I lost an O2 sensor right off the line, car pulled hard as hell, going 190 at the half mile, while losing 2 cylinders, and both heads... a 100.00 O2 sensor... Go have fun... I’ll come watch... I’m retired from driving her due to the heart attack and three subsequent strokes... I can just barely use my left hand... and my car is a manual...oh, and at our car weight, automatic transmissions don’t hold up to mile racing... not if you make decent power...

Here is a video of my record pass and a tribute to and for those that helped or supported me along the road to the record...
As I’m headed down track, look at the sky shifting / tilting back and forth... tire spin and the back end trying hard to lead the car down track... you can see it well On the second pass view, looking out the back..

SSE 4 2SS
You sir, are a bad ass. It’s quite refreshing to learn from someone who has been there done that not just done some google searches. That post was fascinating to me. Thanks for sharing. I’ve been into Motorsports all my life but never really been into any mile+ stuff. I enjoy it all and I might have to go check one of these events out some day soon. I wish you nothing but the best health wise, sounds like you’ve had a rough time. Hope you can get everything figured out! Norm, I don’t have enough fingers and toes for that kind of math  thanks for sharing that in reality I do understand your math.
