Should I tub the Beast?

[muddslide]

Rear suspension are new mono leaf springs and rancho 9000's. They are desighned for drag racing. I think I am overpowering my set up. The next step would be tubs. I am running basicly a dot slick. I have tried different tire pressures from 15psi to 7psi. I guess I could try to footbreak the car?

Just slapper bars though? Are the shocks set soft?

Are you trying to go for the Pro-Street look or just trying to get more traction?
Your problem sounds like you need to work on your suspension tuning, but it could also be a problem with your engine/tranny combo. The more power you make, the more everything needs to be tuned together. Test & Tune.

Muddslide are you going to be at the track wed(9th) or friday(1th)? I might be up there at Bithlo friday with some friends and possibly will run my car, i would like to see the beast and meet you and of course see what that puppy runs!!

double post.my bad

I will be at the track on Sat for the points night. Yes I have the rear shocks set at 9, te softest rating. I like the pro street look but not the price of the tires,lol. Thanks for all the input guys, I appreciate the help on this. I know with my combo I'm over powering the track, thats why I think I should go pro-street or tube chassis. I just refuse to make this car a trailor queen, like my 69 camaro.

do you mean 'hardest'? you want the shocks to be as stiff as possible.

 

[Vinyl66]

Using Rancho's in the rear you should start out in the middle of the range as far as settings go. If the shocks are too stiff they will not allow the rear suspension to work correctly to plant the tire. I have KYB's in the rear of mine and they are terrible for drag racing because they are WAY too stiff.

You also want the passenger side shock to be a little stiffer than the driver side to help with the car's natural torque rotation to that side.
I would start out at 3 driver side/4 passenger. Or 4 driver/5 passenger. Then tune from there if needed.

Look here http://www.2quicknovas.com/craig.html Same suspension as you with dinky 26x8.5 tire cutting 1.35 60' times. Running mid 9's at 3250#.

 

[muddslide]

Thats my point, there is something wrong. Also with Nitrous you can launch with lower settings and increase nos with a roots blower, its launching full boost. Thats the problem with roots blowers, they don't come in easy, they hit hard.

The pics on that page show a Nova wheels up on 8.5 tires. I think part of it is the PG trans. He is hitting the tire hard to loft the front end. I think you are missing something on the set up. What size are your tires?

 

[muddslide]

m/t 275/65, i think. The biggest tire that will fit in the rear of our stangs. Does he have the motor set back?

 

[Dark Knight]

Do you have cal-tracs or just slapper bars?

 

[dennis112]

I have all after market suspension from Calvert Racing.

Dibs---I'd be interested in the Rancho shocks/mono leaf rear springs if you do decide to sell them. Already running the Cal tracs.

 

[muddslide]

I will be selling them if I tub the car. I have slapper bars but I took them off, I don't have wheel hop, just wheel spin.

OK, just wanted to get my dibs in because the Rancho's and mono springs are the route I wish to take.

PM me when the time comes and we can see what we can work out.

 

[muddslide]

Sounds good, I'm going to the track on Saturday. I removed the sway bar and tuned the car a little more. I will let you know in a few days.

 

[washMO66]

What kind of ET and what is that car trapping at?
