Just wondering, why are you riding him soo hard about this? Is there a point to all this?

perhaps it is the lack of inflection, idk. its not that deep. simply making a statement. no point other than i can't get my car to do anything on a 305 gy sc3 at those speeds, i can only imagine how bad it would be on a 275 all season. i'm just asking questions, trying to get some insight on things that don't make sense to me.

What speeds are we talking about here?

FTR, I've said several times in the past that any racing below 100 MPH is just not enough to make any determinations on which cars are faster than which. I think you need to go well into the triple digit speeds to get an accurate assessment. I'll also add that I think the days of 40 MPH starts for roll on comparisons is likewise useless among cars on this level of performance. It's one thing if you're trying to merge onto a freeway against something like a Toyota Camry where you most likely won't need to go WOT. But when comparing 600+ HP cars it is a bit silly since it is likely an issue of traction. So far GM is doing the best at making high HP cars that are relatively light weight but also can apply power to the ground. Camaros and Corvettes apply power more effectively and efficiently than the competition. But still, a 40 MPH start is too low. Like my buddies and I when we ride. I told them that with these current bikes out here, the real race doesn't happen until you are above 110 MPH. I feel like the same can be said with these 200 MPH capable cars.

he said 30-70 mph. his bolt on a10 gt on a 275 michelin all season in presumably cold(er) weather. just saying. sounds fishy.

i agree with what you said about racing.

Agree, the time claims are fishy. Fact is the 'times' that he has posted for his 5.0 came from something plugged into the OBD port. I did previously suggest that he get legitimate times by running that car on the dragstrip to find out if it was really pulling hard like he claims, but guess he was not confident enough to do so. Never saw any legitimate times for his 5.0 posted.

Y'all can go back and re-read my posts from last year at this time on all this. I'm not going to rehash it all again. But, I will say that I was pretty detailed and specific on everything at the time so all the info. is there to review if anyone chooses to do so. The runs were to compare time splits and MAF data before and after the bolt ons I did to my GT. The bolt ons definitely added power - quicker acceleration splits and higher MAF rates. Whether the times were precise (i.e., exactly 20-70 or 19-69) is irrelevant for the point of why I was doing the time splits. I wanted to know if I was quicker after bolt ons and if the MAF increased. Yes, and yes.

Some of you guys must be pretty bored. He doesn't even own the car anymore, move on.

LOL, funny thing is I was harder on him than anyone else back then and now everyone gets on his case AFTER he gets a ZL1.

No, you did not just say the car got faster, you made some sketchy performance claims in comparison to the ZL1, and those brought questions. Like for example, your claim of 30-70 in 2.63 for your 5.0, which did not even have a pump gas tune let alone an E85 tune, and where you live at 2700' ASL to boot. You then said that it's 2.7 for an A10 ZL1 to run 30-70 according to MT. OF COURSE your claim of a quicker time for your 5.0 than for a ZL1 would be questioned, because it's bogus. Your 'precise' 19-69 comment is obviously pretending that speedo calibration is the only concern with using the drive wheels of a front engine, rear wheel drive, V8 car for acceleration times. How can you completely ignore the fact that wheel slip can screw up a timer that is running on the drive wheels?

i agree with what you said about racing.

If I remember correctly, the method used for these recordings was not a draggy or anything worth putting much weight onto.

[BlaqWhole]

Regardless of what was said a year ago, dude has retracted his statements for the most part. i mean come on. he went and test drove a ZL1 and then was soo impressed by it that he went and bought a brand new one and got rid of his GT. Then he started an entire thread about how superior the ZL1 is to the GT (we all know this already) and about how even if his GT had boost and made 700+ RWHP and was faster that he would still prefer the ZL1. And he has been praising the zl1 ever since. If that ain't redemption then I don't know what is. So give the guy a damn break.

We all know that a lot of guys mistakenly overestimated the performance of the 18 GT when it hit the streets. How many guys came on here saying that the GT with a drag pack would beat a Zl1 and Hellcat and preached all that "minor bolt-ons" nonsense? Idaho even admitted that he was soo impressed by the 18 GT and that is why he bought his. And now after sampling the ZL1 he knows the GT doesn't hold a candle to it. So maybe a few things were said but let's face it, we were all debating and I in particular was giving him a hard time back then. maybe some of that stuff was just said to get under our skin. But hey, it did make for some interesting conversations. And nothing was said out of malice or anything like that. So who cares? And why is it being brought up now of all times?

On top of that it was all a bit of speculation and guesstimation and theories etc. Nothing was said as being factual according to what I remember. I will say tho that a GT with full boltons and an aggressive tune and after dropping some weight could give a Zl1 a hard time up to a certain speed. From my testing of my GT I would say right around 100-110 is where the GT will start to lose steam while the ZL1 is still pulling very hard. The ZL1 doesn't start to lose steam until you're over 140 from testing I have seen and done. So these figures were cherry picked as Idaho admitted to doing. The biggest issue for both cars would be grip and controlling the power. But again the same would be true of the Hellcat, GT500, and other similarly powered performance vehicles. IF the GT can remain under control and get some decent grip, then from a 30 drop I could see it hanging in for a very short period of time. Even if it takes the ZL1 up to 110 MPH to actually pass it, the ZL1 will have a higher rate of acceleration way before that. That is just my take on all this. But again, we're talking about a GT with full mods, decreased weight, and an aggressive tune against a stock ZL1.

neither of those mean just because everyone else was slow, you should be too

example: when i raced by car bone stock, here was the scenario

street night
bone stock 18 1LE
3940 lb raceweight (3720 car + 220 lb driver) i weighed the car (and myself)
da 2500'

car went 12.6 @ 115

there was a pray ported im/tb + rotofab a8 1ss car there,
it went 12.4 @ 114

also an a8 convertible with bolt ons/tune, made "470 whp". it went 12.2 @ 116

ive been drag racing various cars (and locations) for a long time. about the only time a car should be down 7+ mph is when the da is astronomical. otherwise there is a problem

maybe that track is uphill or something. i see a lot of underperforming cars come out of MI. maybe all you guys are going to the same tuner, idk.

One of them best me the second time we ran after I showed him how to use launch control. FWIW, most of my trap speeds were in the 114s.

There were also two ScatPacks there that I don’t think ever got out of the 13s. One of them was on Mickey Thompsons.

As far as your own 112~114 trap speeds, I do think those are below expectation with the mods that you listed. Yes I am accounting for the weight of the convertible, as I know someone with an SS vert and bolt on mods, so I have seen what they can do.

Attention in the pits!!

Sense we had the track Re surfaced , there was always that choppy spot at the 1000’ area and the concrete to asphalt transition has gradually been getting worse. We are getting that re done during the first or second week in June . At that point we can open up the quarter mile for competition!!

So, I’m back at LID today. I don’t know if they’ve done the track repairs that were mentioned in my earlier post, but my times so far today are a lot better than where this discussion started. 12.15 to 12.24. Pay little attention to the reaction times on the slips where I ran alone. No pressure = concentrate on 60’. I’ll put it all together when I get someone in the other lane...I hope.

My target with the mods is under 12.00. Within reach with some 60’ improvement..

This discussion really belongs in the drag threads, but since I started it here with the GT500 discussion, I figured I’d close the loop before taking it over there.

Car is definitely getting faster
