Has anyone tried running ET streets without tubes or screws on a 1.5 or quicker car. We did this on one of our other drag cars but it was an auto. Thanks in advance.

1.5 ?

You'll be fine. You're car is light enough that slipping the tire won't be an issue.

 

I meant 1.5 60' times.

 

you'll be fine....

 

Thanks guys, thats one less thing i have to buy. Now if i could just get some 4-link software for free.


How is the car doing kabooski?

 

eh lol don't ask j/k fixed the clutch issue
took it for a spin yesterday
now its overheating
got a new oem waterpump today, will be installing tommarow


I'll get it tuned this month ...if I can keep any other issues from popping up..

 

Good luck with everything. That should be one very well rounded ride when she is all done!!!

With any luck i will have some #s by the end of the month.

 

I run 1.53 with et's at 15 lbs no problems yet. good luck !

 

Any other mods besides the ET streets to get that 1.53? What rpm are you launching at 6k? thats a great 60ft.

 

Diff brace, solid trannie mount, delrin motor mounts, prothane diff bushings, t11 diff. and stock axles. and a slight slip of the clutch. I havent installed the drag kit yet. Oh and 7,000 rpm. could have been better but i hit rev limet at 8,500 in first. Stock struts!

 

my personal best is a 1.48, 7500-600 rpm, tociko/eibach prokit, solid bushings all around, toe links, trailing arms, diff brace, kazz 4.33's......ohh a nice burnout helps

 

Almost everyone I know does not run tubes, but everyone I know are auto v8 guys haha. If you are worried about spinning the rim in the tire, line the valve stem up with a mark on the tire, and after a launch, see if they are still lined up. Another thing Ive heard guys say is, "only rim screw cars get tire shake". Take that however you like.

A car at your level should hook a lot better than 1.5's in the 60ft. Rx-3's are known for 'hooking' in the Mazda world. Your car should be in the low 1.3 60ft.
My buddies factory RX-3 with factory suspension with a turbo motor and TII tranny was doing 1.35's at only 440 rwhp which resulted in 9.80's and that was on a 26X8.5 tire.
Follow the advice of 'Doc Holiday' above. The only true way to know if they are spinning or not.

 

I've never run with tubes. With stock twins and ET streets I was cutting 1.5's. A number of friends with the stock twins also were cutting 1.5s.

Thanks Guys. I'll mark up the stems and give her a try.

 

I run 1.4's and sometimes 1.3's without tubes, and have done without screws as well....no problems thus far.

 

Thanks for the advise guys. I just ordered my chassis software and i am going to try and set it up so that the tires don't hit too hard at first and go from there. I will keep an eye on the valve stems and make sure the tires are not turning on the rims.
