What suspension are you running? rear spring rates?
Cause I bet that has a lot to do with the hop too.

I do not think spring rates will get rid of the wheel hop.

The problem is that the ppf acts like a spring. When you launch the car. the nose of the rearend moves up, and the ppf springs back the other way. It cycles back and forth resulting in wheel hop. It is a similar problem of old leaf spring cars, but not near as pronounced.

The solution is to secure the rearend so it can not spring up and down. I have been trying to come up with a solution myself.

Hop = axle boo boos

My delrin diff mounts really made a difference in the car.

OP, I love your car, the thread and possibly you <3

Doesn't it start at the tires bouncing up and down? I know what you're saying, and I'm not arguing, rather inquiring. I was always under the impression that you want as hard as possible rear and soft as possible in front on a rwd to launch or something like that

It is the wheels suddenly speeding up and slowing down in a cycle. It eventually leads to the wheels bouncing up and down.

The stiffer bushings will help the rear from rocking forward and backwards.

I am not sure if a stiff spring will help with wheel hop or not, but I do know that it helps propel the car in a forward motion sooner, as opposed to the car squating first then moving forward. It will help the ET just a tad.

As far as the front is concerned, you want the shock to be loose as it extends out. This allows the front to rise as soon as possible to help transfer weight to the rear of the car. But when it settles down, the shock needs to be hard enough to smoothly settle the car down and not unload the back of the car, or cause damage to really fast cars that tend to wheel stand.

You're right on the slop and the spring action of the drive train and diff. My differential is secured with the Beatrush Diff brace. You're right on the suspension setup with soft rear allowing it to squat - But I need to give up on launching the car. Drag suspension is not road course suspension at the same time so I'll forget it. I have way more fun on a road course.

I can't wait to see what the manifold does for you.
I get rear end whine for sure! I installed my gears myself so I'm already overly paranoid but it's good to hear that someone else is getting it. It's only when I'm cruising at a steady speed, I get a whine but it's def noticeable, sounds like my dads Firebird rear end.

I this build/thread.




I want to ask you about this..



Understanding you work for them aside, how do you like it? I've been thinking about buying one for my daily driver but am seriously on the fence. If I could locate one locally to play with first it would probably help, but that doesn't seem to be possible.


Do you utilize the 3g/wireless connectivity?
If so, How? Wifi tether? 3g dingledongle?
Do you make use of Google maps for navigation?
If so, does it work well?
Overall function?
Would you recommend?

I use the 3G through my iPhone bluetooth tether.
I do not use Google Maps for navigation
It works but not great for navigation - more for local points of interest.
Overall it's an awesome digital media deck. Awesome sound quality, powerful.

Look what showed up last week while I was traveling for work...


Beautiful piece, came with a raw aluminum finish so I pulled out the Mothers Billet Metal polish and went to work. An hour or so later..

Can you get some inside shots of it for us? I'm curious to see what the velocity stacks look like inside the barrel.

Get it on quick!

I don't have the manifold with me but it looks just like this:



Clean transitions and velocity stacks with nice big openings that taper down to the port size.

Sweet! That looks like BEGI! I need to polish mine as well! Did you use elbow grease or a power unit of some sort?

It's BEGi and the machine that polished it was of the elbow variety.

Why pity?
