60' footing under 1.40
 

Anyone 60' footing under 1.40? What's your combo? Are you using the HR bar, Wolfe bar, coil overs, four link, tire size?

Ca' mon Jack. Do tell!

My best 60 foot was 1.47, I have South side machine bar lowers, Edlebrock adjustable uppers and an HR bar with 28 M/T's slicks on a 10 inch rim. I am pretty sure my pinion angle is at -3.5 degrees from what I can remember. As far as the rear goes, 3.42's with 33 spline axles,and spool.

My best is a 1.51. I think my problem was that I ran M/T 28x10.5's on a 10" rim, and I needed 15 psi in both air bags to insure the tires would not hit the fender lip. This totaly took suspension movement out of the equation. I have installed QA1's all around, fully adjustable lowers/uppers from Wolfe, -3 pinion angle, 3.42 w/ a US/Strange carrier, T/A Perf. cover, and Moser axles w/ Mark Williams C-clip elim.

We'll be checking out your set up soon...... soon as we can get it on the lift instead of under the lift..... :D

That's cool, I am excited that the car is there underneath the lift there, instead of on the lift at my shop! I know your gettin killed over there. I have no worries that you guys wouldn't take care of me once you get started.

not sub 1.4 but 1.41's
t-brake launches at 10psi (electronic boost controller)


stock springs
stock uppers
stock lower (bottoms boxed)
stock bushings
MT drag radials (#23psi)
and HR parts sway bar

the trans, driveshaft and rear are built for low 60s
2004r , 9"art carr 14930, chromoly shaft , spicer yokes and ujoints
moser 33 spline , moser spool , c-clip elems

i probably could cut 1.3xs by dialing boost up a little and toss on some slicks , but with just a stock bottom end i cant be too hard on it.
i run a stageright t-brake which engages by placing trans in 1st gear and releases by bumping out of 1st , because of this the shifter is in 2nd when you leave the line and 1-2 shift is auto trans controlled occurring early (5150) and within the first 60' (actually 42') , if i could carry 1st gear to 5850 the 60 should drop ...working on that as we speak :cool:

Wow! That is impressive! Especially with stock upper and lowers!
The HR bar for me was one of the best suspension components that I purchased. I am running 400 with a brake but I was having a hard time controlling the boost with the manual boost controller that I had. It was near impossible to leave consitently with my old set up. My car is getting the electronic boost controller installed (amongst other things:D)and Jack and Brian are going to check out my rear end set up once they get it on the lift.
Nice times BTW! :cool:

It's scarry how simular our cars are Mike. Gotta stop hanging around Jack!

I know! That guy is bad news!;) LOL!:D

That's a great 60ft with drag radials. What is your burn out proceedure? How do they hook for you on the street? My M/T's [ 265-60-15's ] spin like I'm on water.

OK, since the last time at E-town we discovered a problem with the left rear tire on my car. Seems like @ 139.5 mph the tire starts to rub the front of the d/s wheel opening causing the tire to make smoke and a groove in the tire!:eek:

Here's is an older pic that I found(I don't have a fuel system like that anymore) but the suspension is the same. I think I have to move the bolt that is behind the orignal mounting bolt for the lower control arm. I just hope there is enough area to re-drill. I think I have to move the wheel back a 1/2 inch. I will get it down to my shop and put it on the lift hopefully this week.

Michael, a few years back I had the same problem (but not as severe to cut a groove in the tire though...). The tires had a tendency to rub slightly on the front of the wheel openings even after Eric at Dynotech (R.I.P.) replaced the lower control arms with H&R's. There was a hole that had been drilled (like on your car) to install some "relocation brackets" which changed the pinion angle, but after Eric installed adjustable uppers, they weren't needed anymore and he removed them.
But even after doing this, the rubbing problem was still there, so Eric spoke with Paul at H&R about the problem and eventually was able to get some lower bars that were almost 1/2" longer than the stock length (I think from H&R also, but not 100% sure...) which bolt in the original hole and did solve the tire rubbing problem...:D
Maybe you should give Paul @ H&R a call to ask about this...:confused:

Hope this helps!

Claude ;)

P.S: The bolt which the arrow is pointing at in your picture is there to lock the plates in place preventing them to rotate under acceleration...DO NOT remove it!...but if you plan to keep these lower bars, then have the plates welded to the factory brackets for more safety...

Good idea Claude, but we have been using the double adjustable Wolfe Racecraft lower bars, that way we have the flexibilty to make minor adjustments either way on both sides without removing the control arms..

Ok I understand...but my reply was based on the lower control arms shown in the picture...they look like "fixed lenght" to me...:D

Claude ;)

P.S: Jack, you're SURE I should keep that H&R sway bar on my car?...Maybe it's me who has not adjusted it right?...:confused:..I realize that everyone says nothing but good things about it and I seem to be the only one who's complaining...:rolleyes: Anyways, here's a reply I wrote on Turbobuick.com about the sway bar:

"I currently have a similar setup on my GN (H&R sway bar + upper adjustable control arms + fixed lenght lower ca's...). H&R's parts fit and finish is excellent...BUT...since I've installed the sway bay, my car NEVER was able to launch as hard as it did before... My car used to leave the line with both wheels off the ground but now, it does but only an inch or so. I'm dissappointed of the end result. YES, it did leave the line crooked with one side of the car higher than the other, but it was FUN and gave a good show to friends and spectators ...but not anymore." :(

---but don't worry Jack...I'm still going to follow your recommandations 'cause you're "THE" man!...:D

Claude, thanks for the input! I was off when I drilled the bracket for the d/s. Now I don't think I have enough room to re-drill to make the bracket correct. The p/s side is good, d/s is not. The only way I could make it work with the HR bars is if I bought 1 1/2" longer one for the d/s. And is it a 1/2 longer than stock? Because the South Sides are longer than stock to begin with! AGHHHH!:eek:

Jack, can I bolt up those wolfe bars directly into my existing South Side brackets? That way I can measure the right side and make it identical to what it is now and adjust the d/s to where it is supposed to be, I think a 1/2 inch back.

toofastforyou: I'm with you Jack even accused me of trying to take out the tower once. Now, with the H&R bar, it shoots straight. Kinda boring if you ask me. Although, it is safer. But, my car launches just as good as before, just not much of a show any more. Although, with the car leaving straight, it won't break as much. My car twisted so much that the left rear tire left the ground a few times. And one of the times, when reconnecting, it blew up an axle, and busted the tranny. Yeah, it was an impressive launch, but I think the front went up more than it went forward, then I had to get pushed out of the water box, and towed back to the trailer. Ruined a weekend of racing, and my wallet to boot.

This is going to be a long one!
 

Ok, I think we have it figured out. The rear was actually a 1/2 forward on the d/s tire! That's why it was launching and veering to the right and why the tire was rubbing at the top end of the track. We measured everything. I thought maybe the axle tube was bent, or maybe even the frame. I looked at the upper control arms and they were both equally adjusted. I didn't think that was the problem, but I started to adjust the d/s side arm and the d/s tire was backing away from the quater! So I continued to adjust it all the way out. I had plenty of clearance at this point. We looked at the gaps on both sides of the quaters and measured again! We had it! Then we walked around the back of the car and noticed the p/s tire was sticking out of the wheel well and the d/s side was sucked in beneath the lip of the quater!:eek: AHHHH! So, back underneath and I started backing off the d/s arm and countered with the p/s arm loosening that up turn for turn. I got them both equal and it was perfect. We got out and looked at the clearance, measured again, it was all good! Even the tires were right where they were supposed to be in the wheel wells.... Then I check the pinion angle... There was none! :eek:No matter how much I tried to adjust the arms I couldn't get the angle back without bringing in the d/s tire to the quater. At this point I had it and thought about it the whole night. The next moring we measured where the stock lower control arms would bolt in and then measured where the south sided machine bars were. We decided to move the S/S bars to where the stock postion would be and it then pointed the rear downward. At this point we check measurments and it was equal distance from the wheel opening on either side! I looked underneath and measured the pinion angle and it was at -3 degrees without me even touching the uppers!

Well, tomorrow I will tighten everything down and re-adjust the HR bar. I can't believe the car was leaving that hard, 60' 1.39 and the d/s tire camber was off that much! Hopefully we can make it to the track soon to test it out!

I told you it was a long one!:D

I'll post pics tomorrow.

Nice Mike, I knew you could do it.... setting these up can be fun. Seeing you launch straight will be different... :D

had similar issue with hoopers car with the rear that he put in the #2
it had southside bars on it and the relocate brackets were welded in place , car would pull dead right at launch , uppers were stock , and he had an atr bar but replaced with an HR bar
i noticed one day that the tires werent even spaced in the wheel wells and after some quick measuring with a fist and some fingers it surely was off , big time ...three fingers on passenger side to rocker and a fist on drivers

the fix was he cut the welds loose with a whizzer wheel and used a ratchet straps to pull the rear into alignment measured carefully to points on the frame then rewelded the brackets
hes been going straight out of the hole since

Did he notice any difference in his 60' after he did that or did it just correct his launch?

Any new 60 foot updates?

Yes, that 9.59 run my 60' was 1.393. Thankfully moving those contorl arms and resetting everything didn't effect my times. I was worried moving those lower south side bars up to the stock postion was going to have an ill effect on the short time. I did reset the pinion angle and I had e-mailed Paul Ferry for the instructions for the HR bar. He told me that most guys leave it neutral, but for my application to have a preload of two turns with me in the car. It worked perfect, went down straight and launched great.

Next year we will work on getting it lower.;)

BTW, again, awesome et and mph Sam!

That had to feel good. Good luck to you.

Awesome MPH and Et back at ya!!
