Welds and m and h 325s having trouble

Tried unsuccessfully all day to get into the tens , so close 11.008 x 2 times. Just can't get 0 to 60 under 1.76 128 mph excellent reaction times??? Put 2/3 tank of fuel in , I just don't know. Can't power on in first or I break loose. 15,5 pounds air. Mega 2nd gear burnouts. Any takers

you should do better 60ft for sure I did a 1.72 on a 305/35 R20 Nitto 555 drag radial. Can you slip the clutch more and ease out for the first few feet to get the car moving instead of trying to launch it hard.

Mega burnouts on a drag radial is no good. All you're doing is making the tire greasy. With a dr just burnout until they wisp smoke. That's it. And fill the gas tank completely full.

Full slicks would help a ton. With the m6 you really need to have a dialed in suspension.

okay will fill up tank all the way,less burnout,try and feather clutch but fn hard with this standard and have a consistant 0 to 60 ,if car was lighter life would be good

If these cars were lighter everyone would be in the 10's!!. It's not easy getting a 4200 lb car to go fast. If you can't run a slick I would focus on a full out suspension. Not cheap but extremely effective.

so what do you have in mind for full suspension mods for 1/4 mile,the problem is i just bought my 17s welds,i guess over winter i could find some smaller brakes and buy some 15 inch rims and slicks ,i dont believe there is a 17 inch slick(let me know if i am wrong)also if i run true slicks then that would move me from pure street.its kind of nice to be high tens in a street car

Just because you run a slick doesn't mean you won't have a 10 second street car. I take my car on 6 hr, 400 mile trips. Change tires and hit the track.

If you want to make it work with a drag radial I'd do drag race specific shocks, solid bushings, toe rods, trailing arms, larger rear sway. Basically, if I had an M6, I would get every suspension part I could on it.

Hoosier makes a 28x10x17 full slick. Everyone runs them.

Gd luck!! You are knocking on that door. You have more than enough mph. Even with a crappy 60' you'll get it. Try walking the car out then hammering it.

We always found the M&H's do in fact LIKE a good, big burnout...

Also 15 PSI might be a bit low for a drag radial... with a radial if you don't have enough air in them they will actually start cupping in the center and you'll lose part of your contact patch... I would start around 26 PSI.

Well Im running a 1.68 0 to 60 so the full tank of fuel is helping. 11.1 and 11.058 qualifying runs going to dial in at10.99. What do you think

Thats a good 60ft, make sure your car isn't heat soaked and do what you can.

Stock suspension?

Also, those 3:73 gears aren't helping your situation.

But you should still be able to hook with those tires (if heated properly).

I would never add weight that just slows you down.

Maybe someone makes a two-step for these cars (Lingenfelter I think makes one for the 4th gen), and that way you could control your launch RPM. Like you turn it down a bit if you are spinning and get it to leave more consistently.

I haven't run those particular tires yet but I'm guessing they'll take 15-17 psi no problem.

To SGO, I know someone with a 4th gen that has gone 8.5's on those tires, hooking a strong 60 on them is just getting the right read on the track, playing with tire pressure, suspension, and power management.

So AFCO and QA1 don't make adjustable shocks for these cars yet? They are a must.

Yeah, you would think the front tires would come off the ground with those tires.

I'm guessing our cars are pretty nose heavy, anyone know the front/rear distribution?

With drag radials, it's important to get the weight on the back tires and keep it there. So with the various cars we've run including our 7.40@196 drag radial car, we like to have the nose up a bit to get that weight on the tires and then the drag radials stay planted.

When you run stock, stiff front and rear shocks what happens is that when you launch the nose barely comes up if any at all, so without having the what I'll call the weight more towards the back of the car the drag tires never plant and they spin.

Another solution again helped by single or double adjustable shocks is you can soften the rears a bit so the car will squat down a bit. We normally like to avoid having too much squat because you waste energy by having too much of the initial hit getting aborbed (hard to describe by writing it I can verbalize it better).

To that, in the old 4th gen days we used to sometimes run earlier model V6 springs, and the cars would squat quite a bit.

Examples, one of my old cars:

V6 rear springs, too much squat, shocks in back too soft:


Same day, shocks stiffer in back:


Older shot, no front sway bar, car twisted a bit:


Later shot, V8 springs in back, this was probably a 1.49, left nice:


Nice launches in the white car this is a 1.48 on motor, stock shocks in back but the stock one are like 50/50 so they are pretty good:


1.38 on a 150 shot, 10.008@134 pass:

i dont know,the 373 seem to be the happy medium between good acceleration and first gear running out to fast.this manual seems like it is not the way to go for me ,I get up to the tree and want to feather the clutch but my reaction time gets all f----- up,need more practice

With the 3.45's my car shifts the 1/2 in 1.1 seconds. Which kills my 60'. When we put the 3.27's it shifts right after the 60' but then it doesn't cross the traps with enough rpm in 4th.
