heres the slip, the car does die after the 1/8th mile but only by 2-3mph. i dunno what to tell ya, the car has stock suspension with 131k on it, front struts set on soft, unplugged, then PRC returned to firm and the rear unplugged. i think those pics are in the order i raced that day, first one was @ 4000rpms, 5psi, 2nd was 4200 @ 5psi and the last was 4600 @ 5psi. not an ounce of wheel spin.

New England Dragway does an excellent job prepping and maintaining the track....

after the top fuel nationals a month or so ago i took a walk out on the track and it was pretty much like walking on duct tape. it just about takes your shoes off your feet. now, i doubt its that sticky on a given street wed or friday or even FFW but they do a good job keeping it up.....

street nights SUCK, except on wensday, wensdays the right lane is prepped and has been run on all morning by "the big boys" because NED has a track rental on that day, so the prep is ok at the beginning of street night. however during events, saturdays and sundays the track prep is usually very well. the day i raced was on a saturday, it was quick street and quick rod day, i raced in time trials.

i used to work at a dealership in plaistow. i only went a couple times but it was always right after work on wednesday so that makes sense. the first time i thought there was something wrong with my mark viii because it was strugaling to break the tires loose. other than that it was years ago that i took a tbird up there. i hope to get some track time in next season though. i deffinetly would have loved to see your runs. ive never seen another tbird up there raceing myself....

Ummmm......something is wrong here. Evidentally you have the suspension setup pretty decently and you getting the power to the ground but your times don't add up. I NEVER seen a mid 14 sec car @ 3300lbs lift a front tire. Something is telling me your running out of breath in that car. I have launched way harder than that with the same gears you have in my Mustang and it is a low 13 sec car and never was able to pull the front wheel like you did with similar 60ft times. Could you post a pic of your timeslip? Like I said, something is not right:dunno:

With the IHI on the car, it runs out of steam in the upper RPMs, mine will pull hard up untill maybe 4,800...and it keeps pulling untill 6K, just not as hard as something like a T3 would, if you get a T3 on the car, and do some other odds and ends, your car will liven up after the 1/8th
It's Gumby's fault.

He's launching at 4000 rpm on the rev limiter with 5lb of boost, thats probably 120hp or so hitting the tires out the hole(hince the 1.83 60). Otherwise the car is making expected power for a stockish IHI turbo 2.3.

On a good day and NA my 5.0TC will only pull a 1.90 60ft, but will run a 13.1@105...

I launch at 6000 rpm and have WAY more HP and Torque than that when my rear tires are hitting the pavement. If you have enough torque to pull the front wheel off the ground on a 3300lb rwd car but can't get to the traps fast enough then something is wrong. Either that motor is running out of breath or maybe he has some other problems. I would like to know how his suspension is setup.

he aleready mentioned his setup. its stock. but he can do something you cant by changing the rates on the struts and shocks and unplugging them. i have no doubt that at least helps. hes also got a much lighter 4 cyl in there...i dunno:dunno:

Basically your car has potential to get into the 13's. Your saying 2-3 mph but that is alot. Believe it or not I really don't know anything about the 2.3's even though I have been a member here for awhile. I don't have any interest in the 2.3's since I don't own one so most of the stuff you talk about here on modding the 2.3 is another language for me. I'm usually here for everything else. Maybe a T3 swap is what you need cause it is said your car runs out of steam when you know the hidden power is there.

Actually that does help. The faster that strut can rebound the better the weight transition. Also maybe your right, the 4cyl weighs less. I keep forgetting about that. What I do is take out my front stablizer links which makes a world of difference. I run the B springs and stock everything else the way it came in 1990. So the low end is their for him it is just the upper end taking a huge .

Just as anything else with cars, each turbo has its advantage and disadvantage. The IHI on his car will spool like a sumbitch, crank 18psi by 2,500-2,800, and motivate the bird, but once youre up in the higher RPMs, it cant keep up with the airflow demand on the exhaust side, and it becomes a restriction, which is why his car is running out of steam up top. A T3 will help, but if you go for a swap, look around at learning how to do a home built hybrid possibly, or even an aftermarket turbo.

Ahhh I see. So that IHI turbo would be great for a little diesel, right?:giggle: I would love to see a dyno graph on his car and see that torque. Still impressive for a basically stock Bird.
