What kind of 60's are you guys running? I'm trying to figure how far off I am on my setup. I cut a best so far of 1.688. Relavent mods are Spohn TA, lakewood LCA's, Spohn relocation brackets, 28" ET Radials, 3500 stall and th400. Only have 3.42's in it now but I have a set of 3.73's probably going in this week so that ought to pick up a little.

 

mine with the old 305 was a 1.750
with the late 360 was a 1.649
will have new times with new 305 this coming friday.

relevant mods:
10" ati converter 4000 stall
700r4
stock t/a
stock lca's which i boxed
spohn non-adj. panhard rod
spohn lca rb's
jegster bolt in subframe connectors (welded in since last best)
both were set with 4.10's. i put some 3.73's in her with intentions on spraying the 360, but it died. i know that the 305 could use more gear. at least a 4.10, if not a 4.33 gear.

 

Thanks Matt. I'm going to put the gear and an airbag in this week so that ought to help a little bit. Going to try to get ahold of some V6 springs or possibly some Moroso trick springs soon too. Not too worried about running a number, I just need to get it a little more consistent. Went to the 4th round last night with 1.688, 1.689 and another 1.688 ET"s were 12.242, 12.241 and 12.398 all on a 12.3 dial but in the 4th round I spun with a 1.87 and lost, which sucked REAL bad cosidering I cut a .503 bulb.

 

Best 60' I've gotten was only a 1.79 I do have the LCA brackets installed now though and have material to box in the stock LCAs.

I've been wondering how much bigger than a 26x10.5 I can run. I'll be spraying this year and may be too much for the 10.5s I have on now.

I noticed you're running 28x13.5 ET Streets. . .do those fit without modifications?

 

drag1LE, running the tallet tire will pay off two fold. It will take some gear out of your car as well, for nitrous use. One of the reasons I use the 27 tall tire, is it takes a little out for me.( not for nitrous, not yet anyway). Actually my gear with the 27s is a 3.31, as compared to 3.50, with a 26.

 

Here's a pic of the car leaving. This was a 1.688. You can see the whole car comes up and doesn't squat thanks to the lca reloc. brackets

 

that is exactly how it's supposed to work.

how much pressure are you running in those tires? i've always had good luck with right around 20lbs....remember, the less pressure, the more rolling resistance.

 

I am using 15X10 Prostars with a 5.5" backspacing. I had to massage the inner wheel well a bit and grind a bolt down. I also use air bags so the fender lip can't come down on the tire.

 

Thanks for the advice. I'm trying to determine what tire options are available for me if I need to go a little bigger. I don't really want to modify the fenderwell or raise the rear in order to get something to fit.

 

I run 28 10.5 15w's. They fit with just a little knocking in the inner fender well on a 9" wheel with 5" bs. 1.45 is my best 60ft so far with Spohn TA, Rear drag sway bar, pandhard bar, and Hotchkis LCA's. 4.56 gear with a glide. That rear gear you have is hurting your 60's. 3rd gens are alot of car to get out of the hole. Mine squats in the rear, but doesnt come close to the tires.

 

The 28x10.5s hit the inner fenderwell? Think it could be cured with a wheel with a little less backspacing? I do like the way your tires tuck under your car; looks pretty clean.

4.33s hurting my 60'? How so?

 

Running them at 18 psi.The track that I race at has a real inconsistent surface and is never prepped properly. I'd rather have the consistency with the 60' than sacrifice that for a little less rolling resistance.

 

I'm sorry, I looked at someones setup you quoted. I see it now. The 10.5W's would rub down low towards the front of the inner fender well. just tapped it in with a hammer and that cured it. They are actually like 11.2" tread path. a 10.5 tire is the biggest allowed in my kind of racing, the the W just gives me a little more. I have had as big as a 29.5x10.5, they were just too big and it slowed it down.

 

Thanks for the input, I may just try those W's. I see there's an ET Drag available in that size.

Incidentally, how much tapping did you have to do on the inner fenderwell?

 

My best on drag radials so far is 1.80 flat.

 

It wasnt so much the fender part, but the lower part close to the control arm. I had to tap that in cause of the tire being so tall and wide. They fit good though, the W's helped my 60's more than anything I did to the car.

 

im am hooking pretty good at capitol with just 17 inch nittos

60 foot 1.746

 

Any pics of the area in question? If it's too much trouble, don't worry about it.

Just seriously considering copying what you did, since it seems to have worked out for you and I'm pretty sure with the spray, I'm going to need a bigger tire.

 

in the area circled is where it rubbed, the lower part right inside. The sidewall of the tire scrubbed it. just take a big hammer and knock it back to where the tire won't rub anymore. Jack it up, and get under it and you'll see when the tire goes on. They will fit.

 

1.66 so far. thats with old converter heres a pic IMG_7451

 

I've gotten 1.56's on dinky 9" wide DOT slicks and completely factory suspension. I think I can hit a 1.4x next time out... I'm kinda scared to beef up the suspension on this car because it might stop hooking!

 

Yep, Dont fix it, if it is not broke. I decided not to change my front springs, and struts, for the same reason you posted.

 

I'm kind of the oddball here, but owell.

I've mustered a 2.14 with stock suspension, 300 lbs of luggage, full stereo, full tank of gas, and my father down the track.

 

so far my best is a 1.33 on a footbrake. with 28" tire and 3.73 gears through a 700r4

 

best 60ft of 1.65 with 4.30 currie ford 9", 28.5"x11.50"-15 Hoosier qtp's.. dumping at 4k..

spohn tranny mounted TA (building cross member soon)
BMR poly/poly LCA's (going to rodends)
LCARB's
hotchkis panhard
stock rear springs
cheapo shocks
4 coil spring spacers as a drag bag
1" rear sway bar w/ poly bushings

tires rubbing inner fender and exhaust on drivers side.. i have true duals exiting right infront of the tire, about 1.5" away.. i'll be switching to 4.56 gears and a moser 35 spline setup..

 

Im running a 28 10.5 15 w also, and had to massage a little in the same area mentioned, right in front of the tire, i just rolled the lip foward like described ( use the not so bfh for this) and they are on a old discontinued centerline wheel with a 5.5 back space. relevant well maybe relavent mods are 383 (mild) turbo 350 trans with transbrake, 4800 rpm stall 8 inch converter, 225 shot of nitrous (on a progressive controller), 4.11 gear random tech torque arm stock length homemade lower control arm relocators ( multiple adjustments) 3250 race weight, and for the 60 ft, 1.28, on the rear wheels, want a pic?
