ps I dont mean to offend anyone

I trust what Rich says, and I also trust what everyone else is saying. I never said I don't believe what all of you are saying is true. But you are right, I am not going to take the advice, because it doesn't answer the question I asked specifically.

I wanted to know with my current setup if this swaying was normal, and if there was anything with keeping my current setup that I could do to help me. It's kind of like asking how do I keep my car stock, but get a better time at the track and everyone is saying "add mods to your car" and then getting upset with me for wanting to keep it stock.

I don't want this thread to turn into one of those argumentative ones. I'm not upset at anyone here, and hope I haven't upset anyone either. But please understand what I am asking.

What your trying to do...seems similar to me to a 10.5" tire class race car....

1. your over powered
2. your restricted by your tire


Before you try to tweak little things....you need to make alot more passes, because you can't drive it. You have to find the sweet spot in the clutch/launch so it leaves but doesen't overpower the tires. Go to some test and tunes and just leave on it.....no need to make a bunch of full passes.

Like someone said if you get it to leave good it will sail down the track nice and smooth.....
You see a pro mod leave? when they shake its over......when it comes out the hole good it goes smoothly.


My buddy has a N/A mustang...460 BBF 3 speed lenko, they spent 3 months and ended up having to take it to someone else to get the car to leave on a 10.50 tire at 1100 h.p.

I say if you drive it alot more you will get better. I drove a car once and went a 10.0.......let a good driver drive it and it went over a second quicker.

Just go to the track more........Good luck

CALL911

Thanks. The car seems to get out of the hole pretty good each time. It's just when the RPM's get up past 5500 RPM or so, thats when the back starts coming out.

One launch I spent a few extra seconds in the burnout pit, and when I dropped it at 4200-4300 RPM it bogged! But once the RPM's got to the top it started spinning again.

turn down the boost then.....get it to where you have as much power as you can use.

CALL911

Well, its not a turbo car, so adjusting the boost isn't really that simple. I might try shifting a little earlier though and see if that helps.

Mine was much easier to drive with the TH400 than with the M6. An auto with a race converter shifts very smoothly - you can hardly feel the shift. Are you trying to powershift it?

yea auto's are nice for the 1/4 mile

CALL911

Nope, just shifting quick as usual. No powershifting.

I watched the video. The tires you specified have only an 8.4 inch footprint. ET Streets are measured at the sidewall so they have a small contact area for the weight and power level of your car.

The weight is transfering so I suggest adding some airbags to stiffen the rear a bit (cheap).

You need to work on your shifting as you are losing lot of ET at your shift points. It takes a lot of practice to become proficient at shifting.

CALL911

Yeah, I need more practice at the track all together.

I am having the same problem as you but not quite making the same HP. I have run the 16" et streets and the 16" drag radials and nothing has worked. My thinking is if you are able to launch good off the line and your tires are breaking loose up top then nothing will help that except a change. As I understand it, suspension and air bags are mainly used to get you off the line. However, you dont seem to have a problem there just need more seat time to get a consistant launch

CALL911

Good observation, as that does in fact seem to be the issue. I might try to combat this by shifting at a lower RPM (at least for the first few gears).

wicked_95z

That seems to be your only option without changing anything
