Additional drag strip advice

Didn't want to jack the other guys thread. So with my Roush sc stage 2 and Roush moderate tune, best I did was a 12.5 @ 120mph on nitto 275/30/18 at 20 psi. Couldn't get my 60 ft under 2.3 sec. I had good launches and everything. Advice? Drag tires? Suspension setup? I have a video but this never lets me upload. I'm gonna try and make a YouTube account

You need drag radials at least. Your mph sucks though. That is a big sign of an extremely conservative tune. I would get drag radials and a tune. Also Lowe and goer control arms will be needed with drag radials or you will have a lot of wheel hop. If your car is automatic then you can just leave the suspension stock for the time being and just try with new tires and more power.

Which Nitto 555 tires, drag radial or street? If they are not drag radials putting the right amount of air in your tires will help a lot. Airing down street tires does nothing good. Neither does a burnout. If you were getting 2.3 60 times you weren't getting good launches, if you haven't already I would think about some suspension mods next, rear upper and lower control arms will help a lot, but IMO 4.10 gears are too much with a blower. No traction, and pulls through the gears so fast you don't really make the best use of the power.

The best thing is seat time, as you practice you'll get better each time. Have fun with it and try different things to see what works best for you.

practice and tires i think are key, after quite afew passes i still cant get my car to hook on a 295/55 R15 drag radial. 10.98 at 122mph with a 1.66 60ft is the best so far.

You've got a MPH number that would put you squarely in the 11 second E.T. category, you just aren't getting a good launch.

Is this a manual or automatic car? How are you launching it? And what rpm are you shifting at?

Control arms and drag radials at least are needed depending on how deep you want to go.

I wanna make it a beast but have to wait till money rolls in. It's an auto. I launch at about 1500-2000 rpms. I have a set if whiteline adjustable upper and lowers sitting in my cart at American muscle. Also relocation brackets? I have some tires and stuff that is hopefully gonna sell so I can put it towards. Then some mt drags. What's a good size to put on an 18 wheel? I may also pick up two 17 for the rear

You should try leaving off idle

I have. I got the best time from going at the rpm stated.

Go with some 15"x10" race star wheels and a set of 325/50-15 drag radials, will give a much better launch than any 17" or 18" will.

And it is very pricey but a high stall converter can knock as much as half a second off the E.T. on a 6R80 Mustang.

And those control arms don't help much in your cart at A/M! Get that stuff sold and get the control arms on your car...

And if your car isn't lowered then I'd wait on the relocation brackets to see if you really need them.

You're gonna need some stickier tires for the drag strip.

BTW, is your signature correct? 473/409 from a coyote with a blower? Something isn't right.

The one thing I can't get over is the 60' time. My first time at the strip ever with my stock auto (stock tune/tires/everything) my 60' was 2.1, and that was with my tires at 35psi. He has 100 more HP and wider tires but a worse 60'. I'm wondering how the track prep was.

He had 20psi in street tires. You can put a 14" wide tire on a civic at that pressure and still spin. He needs stickier tires, but the correct air in these will make a big improvement.

Well the day they dyno'ed it, the battery had died the night before so they ran it for a while to charge before I got there. It was hot when they ran it. Im gonna go back up and have it re dynoed.
