60 footing a turbo car? How? No matter what I do, my car only 60' 1.6s. I know my weight/gear (3800-3.23) are not helping but nothing really seems to make a difference. I have plenty of traction....just need more power down low. Here is what I have tried.
off idle or 1000-2000 brake stall nets 1.7s (with 3200 stall)
2-step at 2300 or 2500 gives me 3psi and 1.6s (with 3200/3800 stall)
drop timing to 1 deg on 2-step gives me 5psi at 2300 or 2500 and 1.6s (3200/3800 stall)
I have not tried just flashing the 3800 stall yet off idle. I will try that next plus anything else you guys can recommend. I got the stall upped from 3200-3800 to help but so far has made zero difference in my 60'. I may have someone stand behind me and kick my car in the *** when the tree comes down. Thanks for any useful input. Setup is Incons-346-8:6/1 compression-231/226 115 cam-3800 stall-4l60e

The Cam isn't helping too much.The 3800lb definitly doesn't help the 60'. If your weight was 3400lb you would hit high 1.4's.Sounds like you need to find a way to leave at full boost.
On your 2 step,do you have the gas peddle to the floor?

i dont know what your complaining about, id be tickled to death to get a 1.6
is your car dead hooking? do you think the suspension set up cana be tweaked, or you just think it needs more power off the line?

You need some gear. You also need more boost off the line. With your weight you will probably need to leave at 10psi. at least. What I used to do is prestage the car and then stand on the brake as hard as I could. Then start applying gas and actually slide the car into full stage. You need as much boost off the line as your tires or rear can take. Don't try flashing off idle, that doesn't work with turbo cars.

Mike..thanks. I KNOW you know my situation. So do you think i should try to 2 step it at a higher rpm? I just want to know what to try.
I need more gear...less weight. I need more hair on my head and less weight on my gut...none of these are gonna happen
So I am just trying to maximize what I have.
I got the gas pedal on the floor.....of course....thanks for the input. Mike my boost activated cutouts don't start opening until 6psi ..2 step only gets me 5psi. They are sending me better actuators to open the cutouts fully by 5 psi...that should help spool even more on the 2 step. If none of this works, I'll up the boost and make it up on the big end but I want to get everything out of my current config....that's how you and Harlan got so damn fast. Bastards....if not for yall, I'd been happy at 10.50s

I don't think the weight and gearing are hurting you at all.
At 3,780lbs, and 3.31 gears I've pulled 1.48 60ft (6-speed).
I think you just need to leave with more boost/power.
What is your total timing on the 2-step? Mine comes up on boost fast with 10 deg total.

i had it at like 28 degr on the 2 step at 2300 rpms....3psi
lowered it to 1 deg and got 5psi but no better 60'. maybe I should try different timing or something.i can do that with street tires in the driveway If this bitch was in the 1.4-1.5 range, I'd be close to that 9.99!!! Intmd8, you guys keep me working with your results. I know it's just a matter of getting things perfect. Thanks for the helpful reply

I don't know what you're using to pull timing, but if you can pull enough to end up with 5-10 deg total advance, it will come up on boost fast.
If you're dead hooking and pulling 1.6 60's, than I see no reason to change any parts before you try leaving with more power.

I think there is a difference in launching a turbo car with a 6spd or auto. With a 6spd there is no load so you drop timing and dump fuel to get the turbo to spool. With an auto you have load you just need more. We only use our 2 step to controll the boost. It comes up a lot faster off the step than it does on it.
I think if you take those cutouts off you will fix your problem. Or just get them to open at 1 psi. Your backpressure is killing spool time.

Mike you lost me for a sec. Are you saying i should be using the 2 step or no? I assume yes as I don't build jack without it. Just want to make sure. Tomorrow I am going to home depot and just sit in their lot seeing how much boost/rpm I can get. All this for .35 more et....cars are a crazy *** addiction!!! Understood on the backpressure..ATP is sending new actuators.
Mike you need to post up whats going on the CE...I missed it if you did.

so with lower timing the turbo will spool faster? is this throughout the run or just off of the two step? on my car right now at 3500rpm my boost is right around 4 psi. how can i increase that at that same rpm or is that possible. in order to build more boost do you have to increase the rpm, speaking of the launch that is. sorry for hyjacking post just had a few questions that may be of interest to some

Kaos.I lowered the timing to 1 deg and got 2 psi more boost while on the 2 step. I only lowered the timing while on the 2 step. My setup seems to make more psi as you 2 step it to higher rpms. I am going to see what the brakes will hold today. So far I have only tried 2300-2500 rpms.

it does sound like it is going to be that easy! My linelock was leaking (fitting not tight) and I bet I got some air in the brakes. I will be in the 9s soon I hope. I was reading turbomustangs.com and they have tons of posts about the same thing....turbo/60' and the same resolutions...2step..rpms....exhaust. Wonder if the stock 10bolt is gonna hold up. 22 passes so far and the slowest was my very first pass...10.92

ok update. Just went out and 2 stepped the car to 3100 rpms. it would push bad and brakes barely held UNTIL I dropped all the timing from 3200rpms and down to 1 degree. This let it get to 3100 rpms much easier and built 7psi pretty quick. i will try this at the track thursday and let you know how it does vs 2300 rpms and 3-5 psi
