    I read the first couple,,,,EH,,,just sounds like a bunch of people jelious they can't accomplish the same thing. I don't find the timeslip that out of the oridinary. Somewhat mimics our (drag only) nova we raced a couple years back. That MPH is just about right for that ET.
    My hats off to Rob, I hope he finds a little more speed in the car to ruffle some more feathers over there.

    Of course the ET is about right for the MPH. No doubt the car runs very strong. But that's not the question. Can you explain picking up 33mph on the back end?

    according to this calculator (I wouldn't consider it dead accurate but will at least get you into the ballpark)

    Estimate Quarter Mile Horsepower Requirements from ET

    It would take approximately 652 Flywheel HP to achieve a 9.98

    or Estimate Quarter Mile Horsepower Requirements from MPH

    It would take approximately 672 Flywheel HP to achieve 138 MPH.


    So this H/C/I 01 ZO6 is making around 650 FWHP. Please throw the bone somewhere else other than in our laps. He states it made 457 RWHP and 382 RWTQ. With 15% drivetrain loss that would bring it up to 520 Flywheel and I am sure he doesn't lose 15%. Can we say 100+ shot of nitrous probably 150. Hell the guy is all stealthy says the people that know him, he won't talk about his car, he won't show off his car (closes the hood so noone can look), and then he says he drives it to the track yet people see it trailored there. What else needs to be said to raise an eyebrow.

    Looks about right to me. That's about a typical 20-22% gain from 1/8 to 1/4.
    Our Nova would do 105 in the 1/8 and finish at 135-136 mph running bottom 10's. It was also all motor.

    Even my wifes daily driver is very similar, running 85 mph in the 1/8 and finishing at 110+ mph. Do the math,,,that's a 22% gain from 1/8 to 1/4 on a naturally aspirated car. About identical to what Rob's car is doing.

    I just don't see what the problem is here.

    the are all aproximations and estimates. there is no set dt% loss. that is also estimated. nhra racers dont hardley show thier engines either. so who cares if he doesnt wanna show his engine. so what if he drives it to the track sometimes and then trailors it other times. can you please join marc 85z28 and

    These dyno numbers are a moot point. 457 rwhp doesn't really mean anything. The only way to compare his ET to his rwhp is to compare to other cars that came off the exact same dyno and run at the exact same track on the same day with similar conditions.
    Especially a mustang dyno, they are notoriously low on output compared to others. There was even a member here that had his camaro tuned and dyno'd on a mustang, and made 340 rwhp,,,but the car ran 11.60's at 117 mph.
    Dyno numbers don't mean a damn thing, it's a tuning device and that's all it is.

    Exactly, the secrets are all part of the game. He is probably laughing at everyone that questions the car, I'd shut the hood too just to keep people scratching their heads.
    Check out stock and super stock NHRA racing and see what these guys are doing to make the cars as fast as they are within the rules they work in.

    Take some of that same technology, tricks, and speed secrets and apply them here, only you don't have to stay within a rule book.

    That car did NOT pick up that much in the back 1/8th with an N/A pump gas 346.

    Well there is some expertise chiming in there. All the people in the know, even on LS1Tech are calling BS. Power adder needed, or larger displacement. And as stated with MPH and HP calculators, I said they weren't dead on, but they are definately not 100-150 HP off.


    As for you ShovV, suggesting me and Marc 85Z28 that suicide is the answer for us,
    Can you please take your smilie and shove it up your ass!

    Frost and I don't have to. If you cannot grasp the fact that a naturally aspirated 346 can't pick up 33 mph in the last 1/8 mile, then you cannot read into a timeslip and have no business in this conversation. Please learn a little more about the topic before continuing. I suggest you do a little research on what kinds of cars pick up that much.

    Firebirdjones - picking up 28-30 mph in a healthy running car isn't out of the ordinary. 33 is a bit outrageous. The ONLY cars that do that are big power cars (1000+) that are ALWAYS boosting or spraying.

    you and frost dont have to chime in , not cause you dont want to, cause you cant. you guys dont know anymore about the car than i or any other person on any other forum do. and as far as doin research on the "topic", the original topic of this thread was 500rwhp on a ls6 long block or something else. 500rwhp 346ci can be done, and done with N/A

    its ok, i dont hate you guys

    That's true, it's all speculation from everyone on the internet. Doesn't mean it can't be done, and I still don't see anything unusual about the pass. But that's the internet for ya. Always someone that has to raise a stink about someone elses success. Who cares how he is doing it. And from what I have seen on one of the videos, this has been since 2006 or something like that,,,,sheeeesh and it's still causing a stir

    A local friend of mine (posts as Mightymouse on ls1tech) has gone 8.73 @ 159.2MPH on his ERL blocked 364" engine with a PTE88 (88mm T4) maxed out on his 3800lb car. That is something like 1200-1250 engine HP which, not coincidentally, is the rating of that hairdryer. The car made like 900rwhp with an UNLOCKED converter through a 4l80 and a 9". At the HP level that he made those 8 second passes, his car picks up 30-33 MPH on the back 1/8th.

    It can be done, and has. Not arguing that. But saying that it's possible cam only, or even with PRCs ported stock castings is about as likely as picking up 33mph in the last 1/8 with a NA 346.
