No spool launch...What did ya run?

[wheelin]

I'm curious has anybody just launched it without spooling what was your 60 foot? Would it be possible to pull a 1.9-2.0 60 foot?? Mine did a couple 2.5's

13.417 @ 122.42 in the 1/4 mile. My 60 foot was over 2.5 IIRC. I didn't have enough stall back then. Only 3000 stall at an altitude of 5800 ft in Bandimere. Now at sealevel and it's better. Probably could pull a high 12 off idle with my new chip and injector setup down here.

OK, I'll bite. WHY????

Maybe if you are gonna be running .400 trees or something and want to be competitive without a T-brake? I dunno. The only time I have traction on the street is during turbo lag.

1.57 0 psi launch, well technically its not a 0 psi but its at 0 when i lift off the foot brake , stock turbo/ta 49 and a 2800 10.5" converter RJC boost controller , 26" mt et radials .the tires help tremondously otherwise i would be nothing but smoke
quick spool to a lot of boost (25-27 ) with the help of alky and a good spooling turbo tweak chip.
allowing the converter to flash i usually see upward of 4K rpm before the car actually rolls out , have to remeber if spool is quick you will be shifting 1st -into 2nd during the 60ft , a good tranny rebuild(shift kit etc) will help shorten the 1st to 2nd time , for me the 1-2 shift happens at 48ft at 5500 , if locked i drop to 3800 (locking converter at line) which takes me to the edge of the 60ft mark , if i dont lock the time (and distance traveled) between 1-2 grab is shortened due to 2nd coming in at 4500rpm and the car pulls a little better at 4500 so quicker 60ft times .
with a bigger turbo / stock converter building boost should help , if bracket racing and tires wont hold after a boost launch then you shouldnt build any more than tires can handle and let the slower spool be your traction control and work on consistency even though you will have a lower 60' and ET

I'm in a wheelchair and drive with my left foot and have not figured out a system as of yet that will work for me to spool the turbo on the line. So was wondering if I'm waisting my time thinking I can get a 2.0 60 foot by just mashing the peda or should I try and figure out a better way.

1.71 from 1500rpm with a stock turbo, 2800 red stripe, ported heads and an unknown cam. I just tried it to see what it would do.

try installing line lock to the rear wheels so you can spool up with no foot on the brake or get a trans brake

I do believe the e-brake will give you a one foot launch capability. Just pull the release for launch. Just have to figure out how to get the e-brake set where theres a will theres a way. Line lock to the rear wheels sounds better though.

11.15 @ 121 with a 1.64 60ft.

That was with a shot of nitrous though... No spooling needed.


Just foot-peddling it with no nitrous was good for 2.0 60ft's and 12.20's.

12.002@122mph with a 2.10 60'. This was back in 99. I had ported heads, 212-212 comp flat cam, precision fmic, PT 54 @ 24psi, 42.5 injrectors and methanol, and a loose stock converter . Early next spring i broke a main cap in that engine. With pretty much the same combo on a girdled engine and a ton of methanol i went 6.70@102.9mph in the eighth launching at 13psi and i think a 1.58 60'. Neither of the above was on pure race fuel, a 50/50 mixture at best and the 12.0 was with nothing but 94 octane :biggrin: . You have to drive part throttle till 55-60 to prevent smoking the tires. That combo did well on the street scene. No one expected any mph when they couldnt smell race fuel. HaHa

I've thought about that 1st option not sure I would have enought time too pull up,put in neutral put e-brake on reach over with left had put in D then move foot over to the gas raise the rpm,pull e-brake with the left,then get the left arm back on the wheel . 50-50. Second would be to easy into the line with foot on the e-brake( 1 click down) then when I'm perfectly in push it down all the way. 50-50 might be to far passed or before the line.

That's not what a line lock is designed for and wont hold the brakes any harder than your foot can do.

Ive pulled some 2.1-2.2s leaving off idle and ran 12.2 at 117. A lot of its in the combo, just make sure your converter is rated higher than your turbo requires and it should pull so 2.0s...

Nice thats what I'm looking for....

that was with the old .63 exhaust houing on the car. It probably couldn't pull that anymore off idle with the .85. I would recomend a 32-3400 stall with good torque multiplication with a Ta49 and a off idle launch it should be able to pull a pretty respectable 60 ft if it hooks. You also may want to talk to your chip burner and see what he can do to get all the power ya can down low. Good luck with your goals man.

Edit: also i noticed you have a stock intercooler (at least nothing is mentioned in the sig) i remember changing mine and there was a drastic improvement in spool up)

I have the stock intecooler with the dutt neck

i know thats not what it was designed for i am just trying to help this awesome guy that doesnt believe in giving up because of a wheelchair. and yes linelock will hold as good as your foot because it will lock on what psi your foot initially was pressing

 

[salvageV6]

A dual line lock system could work in this case.

One button for the rears at burnout one for locking both front and rears at the line.

Or else a hand operated throttle system.
