Ran new best with new tires. 28x10.5
1.553 60 ft
11.528 @116.48
Procomp fuel pump broke on my last run during burnout. It s a holley black knock off. The electric motor separated from the pump housing. I guess u get what you pay for. Was able to drive it home. Had to punch it and duct tape it back together to make contact. Lol
Here's a pic wheels up!!!

Re: picture from test n tune
If I could make a suggestion.
Leave the car alone. Don't touch anything. Take it out with a fresh, clear mind and try it again. You may get the car into the 11.40's the way it sits. You just need some additional track time. No one has ever maxed out there cars abilities in 1 track vist with a few passes. Trust me. Theres more in it.
This is how.
turn your 2 step launch point up to 4200 where it was previously slightly spinning. Work with that as your new launch point. Thats probably where your 1.49- 1.50 60ft is sitting. Once you can get the car to work at that RPM your almost garunteed some results. My advise would be to get in the burnout box and melt the tires till the rubbers falling off them. Let it fly at 4200 and post results. If that doesn't hook, than start figuring out what your suspension needs to make the 4200 launch hook.

Sooo, maybe this worked?

Re: picture from test n tune
Very cool man! Nice pic. Is there a big difference between the Iron Eagle Platinums and the Iron Eagles? I have the same heads as you except they are not the Platinums. I want to run about what you do for MPH but I might need to go a little more on the cam. Not sure. Just more curious than anything. See my sig.
Props.

Re: picture from test n tune
Best run was leaving at 4000 on two step. Was able to cut pretty much the same 60 foot on my 4 yr old 26x11.5x16 et streets. I didn't have time to leave at 4500 like I planned. Darn fuel pump!!!!!

In Jegs it says they flow 10% better. Different combustion chamber and runner design. Five angle valve job (if not sure if originals do).

Re: picture from test n tune
Quick question for you all. A guy at work (fellow third gen guy) says it looks like I have too much seperation in the rear. There is more in this pic than at ride height for sure. Can you even have too much separation? Or does it look about right?

Re: picture from test n tune
Now that you point it out, it does appear to be lifted far up. I don't know suspension though.

Re: picture from test n tune
bottom hole lowest position on lca also running highest t/a front mounting location and -3 * pinion angle

Re: picture from test n tune
ok, front TA mount (up and down) does nearly nothing. not even sure why folks have that adjustment.
try the middle hole on the lca's, it'll hit the tires a little softer, and should cause less seperation, you want the car to leave basically even. too much squat can cause tireshake from wheel-hop, too much anti-squat can "bounce" the tires (picture a little kid spiking a basket ball), or cause them to ball or fold up, which can also cause tireshake.

Re: picture from test n tune
I'd agree w/ matt, try the lca up one hole. The closer you can keep it to level or slightly upward while still maintaining traction, the faster you will go. - You want the energy pushing forward as much as possible, but obviously some energy will have to be used to transfer enough weight to keep the tire's planted.
While in theory it shouldn't change anything, I have seen several racers have on track differences w/ a front mount height adjustement. Not neccessarily a "performance" gain, but a good tuning point for consistency/wheelie control.

Re: picture from test n tune
Does it really matter? As long as he's only lifting the front a few inches off the ground and isn't reaching the end of the rear shock travel/bouncing the tires off the pavement/spinning it's not loosing any time. I suspect that if the car hit the tires harder with more power it might become an issue, but right now it appears to be working well for the combination that he's running.
Funny, a few years ago I kept recommending not running the lowest hole on a lot of combinations and people all thought I was crazy.

Re: picture from test n tune
^ I remember that.
Agreed, just pointing it out so that your statement wasn't taken as "all-encompassing".
For a long time I thought having that adjustment did more, but through the years have found that if that adjustment makes a big change, something else wasn't even close in the first place.
