Ran with the New 410's - North East F-Body Association

Camaro9969 · #1 08-27-2011, 12:03 PM

So i ran it last night after doing the rear over with 410's from the 342's and i didnt do better My 60ft dropped to a 1.786 which isnt bad its prob got more in it which will help just its in a 10 bolt with a 6 speed so i dont go to crazy with it. But i figured the new gears would get me to the 11's and doesnt seem possible with this Cam only set up. Maybe some weight reduction? Traction isnt the issue just seems not enough power to do it. I could buy a new throttle body maybe just to add a little more hp. But anyways heres the slips from the Old rear end on the LEFT and the new gears and rear on the RIGHT. Think i can get 11's or is that not going to happen with this set up? Maybe some ideas to get this car going quicker. Video is below also. Thanks
I ran a 12.1 a few weeks back with the stock rear but couldnt find the slip but this is my second best time i ran and they are very close

yeah you will run 11's at NED. i bet the DA last night up that way was over 2500 feet. better air and the car has it. but if your set on running the 11's in the heat. a bit more power or less weight is my suggestion. what do you have for weight reduction now?

Also 113 mph might not be quite enough for 11s unless you can really launch the balls off of it, the high eleven six speed cars I've seen are usually hitting around 115-117

Ya i was thinking maybe a different throttle body maybe? not sure what to do for some quick power besides NOS, I actually had it full weight with a toolbox and jack spare tire. haha The air in NED is better than lebanon???

I still am surprised it didnt run better with the gears i know it feels better becasue of the 410's but still it launched pretty well at 1.78 thats not bad at all and figured that would be what i needed for a better time not worse. I need to figure out my shift points are. I see on the Dyno sheet the highest torque is at about 4900 rpm so maybe i should shift earlier to keep it falling right at the 5000 mark.
Heres my dyno sheet maybe you guys will see something that i dont haha. My torque just falls off the map after 5000 that kind of sucks

Where are you shiftung? Gotta keep those rpms up shift at like 6500 your probably shifting slowly and the rpms are dropping off

113 trap speed is really only half the story alex. its an indication of power to weight ratio more then anything else. like John sed check your shifts. and lighten her up!! thats what i say and before the seasons over the car will see a high 11!

Heavy or not the car can't e over 3800 it's not even a vert with his dyno numbers he should be trapping 117 easy. It's a clear ibdication he isn't using the powerband or his car isn't making the power it should. Also get someone to go inside the car and floor it. Then go to the tb and make sure it is at wide open. I had that problem before where the throttle cable had to be adjusted

problem with dyno numbers is they are misleading. with a sae correction factor to sea level it shows the car makes XXX amount. now take that car and put it at 2500 feet of elevation. Now it In REALITY makes only YYY amount. see what im saying. i have gain 2 mph from weather. and i havent really raced my car that much yet and have seen it. Tony broke out last year because the da had dropped only 500 feet from one run to the next.

Ya ill lighten it up as much as I can maybe I'll take the seat out but its pretty light. I've been shifting high like 6200 but when it drops its already above 5100 rpms when it goes into the next gear with these 410 gears so when I'm shifting gears maybe I'm out of the torque and should shift earlier. Well ill try again Wed at Lebanon. I want to get up to NED whenever u guys go let me know its a farther drive but ill come out. What you think about a new TB?? Or the ported one good enough?
