John,
Yeah, it launched REAL hard. I was thinking about it today and thought it may be fuel related. My Syclone does the same thing if I don't have at least 1/2 a tank. Launches hard and noses right over and then recovers. Just thinking with the increase of Gs on the new TC at launch just might cause this. The only change has been the TC, right?

Just a thought. Hope it works out.

Mike :flag

Don't drive it into the lake....well not just yet. :)

 

Mikie, you could be right, I was down to reserve. Ya, the convertor was the only change, but the car has been slowing but not like this.

 

Looks like the heads worked ok I would assume? :cheers:

 

Eric..

GREAT #'s :D I just know in the fall it'll run 11.4's Who's gonna do the roll bar ;)

 

C'mon Mackey......DUH!!!! Put some gas in that thing!!!!! Mine will just about stall if i try to launch with less than a 1/4 tank. Nowadays i try to run with at least 3/4 tank. The extra weight helps with the hook, but hurts ETs a bit.

Eric, I expected Chris' car to easily run in the 12's, but it was well into the 13s :(

11.4's would be nice! Believe it or not the track photographer snapped a photo last night that shows both front wheels come off the ground on launch! About 0.75" on the right side and 0.5" on the left. Needless to say we ordered the picture. That's on 17" drag radials mind you and no other changes to the suspension....

The roll bar is going to be done by Neverlift.

RichS, yes the heads seem to be working well. Based on the success of Rich's GS, I had Morgantini Racing do the heads on my Dad's car. :cheers:

 

Eric.. I think it might be a good idea to remove the front sway bar.. it was a big help to me.. When I had the 2800 converter & 17" drag radials, many times it would just "chirp" or spin 1 revolution.. screwing up my 60' by a couple of hundredths.. Even now with the stock converter I still have the sway bar out..

Give it a try.. & I KNOW you or your Dad wont notice any difference in street manors. Also think about front skinnies.. you'll save about 50 lb of unsprung with just that..

Oh... update your sig.. for best ET :D Congrats :cheers:

Neverlift Is the best. Leo did a super job on mine. I know you'll be very happy with his work.

How come no one took the bait? ;)

I was hoping the car would go 11.4's the first time out. Even at the 11.8's of the other night, that's a 6 tenth increase from just ported heads with "allegedly" no other changes to the car. I was waiting for someone to raise the :bs flag on me.

Well since it's raining and the Forum is a little slow, anyone care to guess what else was changed? Hint: it wasn't the cam, and it has nothing to do with the exhaust. And it certaintly isn't N2O.........

 

New injectors, & or reprogram of the computer.. Breathless Air intake :)

In my earlier post I suggested going to Weld Pro Star Wheels.. if you do & remove the sway bar your gonna save almost 70-80 lb of unsprung weight..Depending if you use ET Street or DR in the rear. but that alone is good for .08 - .10

 

I read that last night and was wondering. I though man .60 with just the heads and intake. :eek: Then I thought headers, but you just said no exaust work. How about a 4000 converter and new program? Unless when the heads were off you had the motor apart and stroked it or had one waiting?

John,

With my 85, when I ran 1.7 60 fts, I had to have 1/4 tank or more, otherwise the pump would pick-up air for a split second at the launch, and about 1 second later and 30 feet out the air would hit the injectors and it would nose down hard. With 1.6 60 foot potential that has to be 1/2 way between 1/4 and 1/2 tank, now that I run deep 1.5's, I have to have a solid 1/2 tank of gas otherwise it will do it every single pass. When you don't have much fuel in the car, it just sloshes to much for the sock to pick it up.

But that is with a 85, I doubt if your 96 needs to run that much fuel, but you probably want to start out at 1/2 tank and work your way down to see where the problem happens.

As a note, this typically cost me about 1 tenth in et. You'd think it would be more, but isn't.

If it isn't that.... then the only other thing I could think of converter related is if your converter is trying to lock-up in 1st gear.... that would probably nose it down hard.

good luck

Rich,

I knew you would figure it out! You are correct, it is now a 396 stroker. The other changes are a 52 mm throttle body, 42 lb Ford injectors, and new PCM programming. The factory exhaust remains, and so does the hot cam, 4.10 gears. and the same 3000 stall convertor.

I fully expect the car to go 11.40's when it's all sorted out. It's got some quirks in the shifting and the throttle isn't opening all the way (it's about 95% open, I need to modify the accelerator pedal).

So after these quirks are resolved I expect it to routinely go 11.60's and with good weather 11.40's. that's essentially a full second over the 350/unported heads combo.

Yeah, we ditched the sway bar last year. It can definitely tell it's not there though when cornering hard, but it's a good trade-off for the better track performance.

Regarding the 15" Welds, that's a great idea, but it goes against the theme of the car which is a total sleeper. When you open the hood it looks like a stock LT4. No one would expect it's anything more than the typical high 12 second LT4. Not that we are going to street race it or anything but that is the direction that we took with the car and would like to stick with it.

Better wheels and tires and/or a lower stall convertor or gear change will be considered though if traction is a continual problem.

The other aspect of the car, is that my dad will not tolerate any driveability problems at all. That was our reasoning in sticking with the hot cam (a bonus is that the hot cam will also pass emissions).

So now with the hot cam and the 396 the car drives beautifully with a very smooth idle. Obviously with a bigger cam, long tube headers, etc the car would probably run in the 10's but for now we will stick with the current set-up.

 

Eric, i kinda glad to hear that it's NOT a 350 anymore. If you were running 11.8s with a 350 (heads or not), then there was something definitely worng with my car. At 11.8s for a 396, there's still hope that my poor times were weather related and not mechanical.

Good luck squeezing the rest outa the new steup.

Good luck with the new setup. I am sure you will be able to work out the quirks. Are you going to put in a roll bar??? If so doesn't this go against the sleeper look???

 

It does go against the sleeper look, but if you've ever looked at Mackey's car, then you know it's very difficult to see his roll bar. His was done by Neverlift (see prior post in this thread).

 

I wish my insurance company couldn't see it :yesnod:

 

Talking rain for this Friday :banghead: :banghead: :banghead: :banghead:

 

No rain for fri its sould be nice, there saying 78 deg. nicest day off the week. :D
