Re: Porpoising on launch help

Glad you found something. With the wheelie bars off were you able to make the suspension move with shocks loose?

Re: Porpoising on launch help

I don't know if that's too much spring or not. Try adjusting the shocks like I suggested and see if you can move the car. If you can't, and those shocks are new, it sounds like something is bound up.

Re: Porpoising on launch help

First thing, set the rear shocks to full loose on both extension and compression. Can you push down on the rear of the car and make them move easily? You should be able to pull up on the car as well and see them move a bit. If you can't, there's a problem with the shocks that needs addressed. You sa...

Re: Porpoising on launch help

I watched the video in slow speed and I'm seeing very little if any rear extension on the shocks. You said you've tried different settings, do they all act like that? Were they full tight extension in that video? Front doesn't look like it has very much travel in it. I doubt you want full loose, do ...

Re: Poor prep and radials

If I were you, I'd try the M/T Pro Bracket Radial next go around, if you're gonna stick to a radial that is.

Re: MSD7531 and E85

There's a lot of questions as far as how much and how long to ramp the retard out. If the car is hooking ideally use no retard at all. If the car is just barely hazing the tires at launch, probably only a degree or two for say 1/2 second - just really depends on what it's needing. If it's totally nu...

Re: MSD7531 and E85

I really doubt this is any big deal to take a bit of timing out at launch, you could use the Launch Retard feature on the 7531 to do it. Not sure how many degrees you're talking about but I don't really see it having any issues to take out a few degrees of timing out at launch.

Re: Altered chassis problem

Are other similar cars having problems too at the same track? Or is it just your car? - Just wondering if you're dealing with more a track prep problem than a chassis issue. I assume you've aligned the front end? Got any video of it during one of these passes when it's moving around? Any drive shaft...

Re: Poor prep and radials

Poor / Little Prep and a drag radial don't work well together. If that's the kind of track you're going to be on you'll have better luck with a slick.

I had an old 427 tall deck that was out to 505 with half fill, could drive it around a little around town without a problem.
