Sounds like a two step to me. Like its building boost . Thought it might be rear mount turbo at first.
The article lists type of heads. the cam metnioned sounds pretty tame.The compression is listed at 11.5 likey from heads shaved as it says stock bottom end. They also say it makes 450 rwhp which sounds about right..trik flo heads, fast 90/90 tb and the mentioned pretty middle of the road cam.
So again if you forget the et and just crank in mph there is no way in hell a 450 rwhp car can do 138xx mph. Don't care if GOD HIMSELF was driving! Something don't add up.
I can see some crazy numbers if you go to like 15 to 1 compression, a stupid crazy solid roller cam, awesome heads then could see a stock displacement
ls1 making maybe 600rwhp and turn some 138mph times maybe..if it was light and this car is reasonably light.
Almost any buddy that is even approaching 138 mph on 346 is running all the bolt ons with big spray or FI.
Its really a simple question. How can 450rwhp do 138mph. Buddies m6 which ways maybe 400 pounds more does 11.8 best at 116 or so at 1600 ft track on et streets doing think it was 1.8 60fts. So sure he could be getting maybe 11.0 if he got the 60ft down to 1.4 but his mph isn't going to go up because of that. He has 420rwhp.Heads,cam,headers bolt ons.
I dont' care what something is still messed on that car..
You need to ask what type of dyno was this.
Answer: A conservative Mustang Dyno.
I love Mustang dynos!
Weird everybody says that dyno's aren't true of what the car can do and to run it at the track and see what kind of numbers it puts down. Now we have this car and everybody is talking about how can a 450rwhp car run 138mph. See some cars that get 450rwhp and run like shit and some that are insane. So this is the case with robs. My car with just a decent size cam put out 440rwhp, so i highly doubt that robs is only putting out just 10 more rwhp with a little bit smaller cam and a great set of heads.
I need to go and pick up this mag! Was following his write ups on his car since the beginning, since I wanted to do something similiar to his, but all it takes is $$$$$$ and that ran out.
Looks like some people have the money to throw into the car but have no idea or patience to set the car up right. I'm sure rob spent a decent amount of money but put tons of time into the car. Look at the end result.

mustang are not that much lower so even with 500rwhp which is really hard hard to get with a pretty mild cam ,decent heads, and 11.5 to 1 and headers. Still 500rwhp might give 125mph or so not nearly 140mph.
I guess have to side on the doubting thomases side. This car just makes no sense. Mph shows true hp the car is putting out better than et. A 1.4 60ft is awesome for et but don't do much for mph.
But the videos show the car running what it runs. So can't really explain it but it seems to transcend the laws of physics.
Still 500rwhp might give 125mph or so not nearly 140mph.
You may want to check out untuned C6Zs with DRs. They have trapped up to 129+ mph and have nowhere near 500 rwhp.
Obviously, you have your doubts and nothing will convince you otherwise; even a reputable publication. So you might as well stop because it will only frustrate you. However, stay tuned for more amazing feats.
CorvetteForum showing that Jamie Furman, driving a stock C6 Corvette Z06 with run flat tires got under 11 seconds, 10.98 to be exact at 129 mph at the Maryland International Raceway. The time was validated by an official at the track, setting the record for the fastest production vehicle! and not sure what alititude maryland was or the density air that day. Could be some more potential for more mph for sure there and quicker et. And of course that time was on runflats not even drag radials. And forgot would assume vettes gain some mph over fourth gens due to superior aerodynamics?
So assuming z06 c6 dyno around 400?? So I guess taking into acount some weight reduction and good density air/alititude and maybe a mustang dyno reading 10 % lower than dynojet looks more doable.
So then there should be quite a few 500rwhp c5 stock displacment cars that should be able to duplicate the mph of this car if not the et and 60ft. So what are the closest to this?
I guess was going from our track where the alt is 1600 and density air can be a lot worse most days. As said car club guy with SS pushing 420rwhp dyno can only manage about 118mph and weight is about 3600 raceweight. So quick figuring add another 4mph for weight form 3188 to 3600. Add another maybe 4 mph for alt or density air maybe even 6 tenths. So we now get like 128. And if it was mustang dyno then starting to make some sense.I want to see the dyno sheets though. From an independent shop.
I found one corrected dyno sheet. This happens to be 467 HP which is the highest to date. It dynoed between 449 and 467.
Do you wish to purchase this motor? We are moving on to bigger and better things.
Rob has been banned from here.. I'm guessing because shops like TSP are pissed that AMR is beating their gutted racecars by almost 4mph in the 1/4.
If TSP is going 134 MPH in +1700 D/A with an automatic and a large stall converter, and this C5 is going 138mph in -1700 D/A with a 6-speed, I'm pretty sure no one at TSP cares... The two cars are completely different in aerodynamics, drivetrain and setup, similar only in the fact that they both have stock 5.7L shortblocks.
Anything above 128mph with stock cubes and N/A is moving on pretty well, really anything above mid 120's is doing good. I am impressed with Robz's car and I believe the times. I have not seen the new GMHTP issue, but look forward to it just for this article.
BTW, "Paint It Black" you might think a little bit more about what you post before spreading your Conspiracy Theories from that other site full of misinformation and one-sided viewpoints. If you do not have any worthwhile content to add, I would recommend not making similar posts in the future.
Just to add a little to this, the corrected dyno numbers don't mean squat when racing at a below sea level density altitude. I hate to make the correlation, but it's like an N/A engine with a little bit of boost, some of the math savy guys might be able to give you better example. Same situation as to why stock LS1's run mid 14's at 7000 feet D/A when they run low 13's and 12's at sea level tracks.

Of course, we know this. I was only providing the info requested. Some guys like fancy graphs with squiggly lines and many colors. Not my cup of tea either. I'd rather be racing.
Cartek has a heads and cam car (Alex's car) that dynoed just over 500 rwhp on Cartek's dynojet. It can be done. I don't know sh*t about a mustang dyno only that I know it usually reads lower hp #'s.
Robs vette is under 3200lbs and Cartek Alex's is heavier (don't quote me but I think it was just over 3300lbs).
Alex ran 10.3@ like 132mph at Etown, not Atco where the air is better and the track hooks better (those of us who have raced at both know the deal).
Rob had a great day condition (da) wise-has a sick clutch and trans, is more aerodynamic, is lighter and has alot more $$$ is his car than Alex has in his (Alex still has the stock brakes in his car). Alex runs taller 28" tires, which really eat up the mph, Rob runs 26's I want to say but they may have been 27's-no way they are 28's.
I personally was at the track on the night at Etown when Rob ran a 10.17 I beleive it was.
So if you want to compare the 2 cars I'm using as an example at the same track and similar conditions (I was there when Alex ran his best time as well) there is less than 2 tenths difference between the 2.
Also rob ran his time at a rental day, when you can really fine tune and hot lap the car for a better et and mph, Alex ran his best time on a t+t night at Etown.
Also both racers can really shift their ass off.
I don't see what's so unbeleivable when comparing the 2 cars.
Also another really important piece to mention in both these cars is that they both have great tuning. Tuning is key and to be honest-some people (shops) just can't tune as well as the guys that tuned these 2 cars.
Also rob ran his time at a rental day, when you can really fine tune and hot lap the car for a better et and mph, .....
Mark,
Actually Rob's pass was at a Test & Tune night at Atco. The air was decent but not optimal. We have another vid somewhere showing Rob writing his time in the dew on the top of his car. And you are correct about great driving & tuning producing great results. That is why AMR has produced the quickest stock bottom end N/A corvette out there as well as the quickest bolt-on only C5Z corvette.

Don't leave out the 500 pound weight difference either, as if DA and trans type were the only real differences..
if we're going to make comparisons, lets be fair now

There's an AMR cam only car over in the Eastern section (Demonicbird00) that has gone 10.99.
Car went from 98.11mph in the1/8 to 127.45mph in the 1/4
That's 2 cars outta there that I know of with big MPH differences from the 1/8 to the 1/4
Both stick cars.
They must be doing something right over at AMR
mark, im a Race Proven Motorsports cam only car lol. not taking anything away from AMR, just want to clarify. and i was invited by Rob to attend their rental last week.
but like what was stated, great tuning,gearing shifting and everything else that makes the car what it is.
you cant just slap on a h/c combo and expect great times, it takes work and nothing can be over looked.
ohhhhhh brandon I apologize, for some reason I thought you were an AMR car. So Fran did your set up. But my error kinda makes my point even more about the mph from the 1/8 to the 1/4 and how you and Robs cars accelerate very well between those points and how competent shops and skilled racers can get down the 1/4 in a hurry.
I thought Rob ran his best time at a rental , makes the pass even that much more impressive.
Gary, what size tires does Rob run?
I found one corrected dyno sheet. This happens to be 467 HP which is the highest to date. It dynoed between 449 and 467.
Do you wish to purchase this motor? We are moving on to bigger and better things.
Great ET and MPH, I am impressed.
A corvette is very aerodynamic and the engine compartment is sealed up tight as well, very light weight clutch, efficient tranny, excellent driving and great engine combo makes for a impressive set-up.
I can’t make out the numbers on your dyno sheet. What RPM did you make peak HP?
Congrats,
Bob
