Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.

Phipp,
This is what I have for you.. http://73-ls1.com/67trucksetlist/Eng...hipnumbers.JPG http://73-ls1.com/67trucksetlist/Eng.../Phipgragh.JPG http://73-ls1.com/67trucksetlist/Eng.../Phipp13ET.JPG Drag analyzer says you would be best shifting 1-2 at 6,900 and 2-3 at 6,950.. Seems a little high with it peaking at 6k. It also says a 4,200 verter would be best, moving your 60' to a 1.50 and netting you a 11.40 @ 111.7.. |
Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.
Sinister..
Here is are some motor numbers for you.. But, as far as the car goes, what type of car is it? The program is set for our trucks more or less. So the frontal area and drag coef is going to be way off. They have a bumch of profiles and I can drop it in a similar car. If it's a tube chassis glass body, well, they have profiles for that too :) http://73-ls1.com/67trucksetlist/Eng...Sinister65.JPG http://73-ls1.com/67trucksetlist/Eng...ter65graph.JPG |
Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.
Ok.. Not sure I'm going to get to much further..
Phila, BTW 104+4.. You ICL is 104 and you cam has 4* of advance ground in to it making your ECL a 112.. Thats what 104+4 means.. |

Thanks Shaun, that makes sense-
I'm in no hurry for the numbers- just grateful. -Todd BTW- my daughters (7 & 9) enjoyed the videos of your track passes- Vrooom! |

Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.
750 stock. The mods were more for idle than WOT flow.
Aside from that, I knife-edged the butterflies, cleaned the casting on the throttle body and thinned the throttle shafts. Let's just say the carb flows at 775 CFM. Does that help? |
Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.

exh.gross .568 @.050 int. .325 exh. .334 I have 2 crank pulleys,5" for street 6" for drag. Blower pulley is 3.05". Drive ratios are 1.97:1 and 2.30:1. |

Tmiller,
Here are you numbers.. With out a weight on the truck it will be hard to give you an ET through the other software.. http://73-ls1.com/67trucksetlist/Eng...lernumbers.JPG http://73-ls1.com/67trucksetlist/Eng...leroverlay.JPG |

Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.
Thank you much. I like those #'s. Looks like I wasn't far off on my estimate.
What's with the spark adv.? Looks low. Is that timing the program put in? I haven't weighed the truck, thats not all important to me, just wanted some numbers to see if it's a good setup because it sure feels goood!!! |
Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.
Thank you Shaun! I'm looking forward to dropping in a 3.73 rear.

Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.
Tmiller,
Probably because I had 96 octane gas being used.. I put 110 in and it moved the timing up as well as gained you aprox 40ftls through out the curvt till 4k rpm where it started to reduce. At 6k the TQ lines where the same. |
