hey, i was wondering if its normal for a 6 spd, 4:10 geared ls1 to not be able to spin 1st gear without dumping the clutch. it hooks and pulls. the tires are 245/50 bridgestone potenzas.

question

I would say you should be able to light those up in first.
What if you slowly accelerate to like 3000, let off and then punch it?

def should be able to..
mine with 3.42's will spin some decent 275's in first.. and then again shifting into 2nd. What RPMs are you punching it at? at low rpm mine will catch at first, and once the rpms get a little higher start to lose traction

ok ill have to try that. i was punching it more low end prob at 2000/2500. it will spin a little when i hit second tho

What suspension mods?
What clutch?
How many miles on car? clutch?
Any times or dyno runs?

Also keep in mind that it's actually harder to spin with 4.10s than 3.42s. You have good tires, though a bit smallish. If your clutch is factory and/or you have some suspension done, with those gears I can totally see a dead hook.

ok, i boxed the lca's and the panhard bar and the clutch is stock with 120k. i hope to go to the track once i got lt's and full exhaust

I don't see how people keep posting up not being able to spin in first gear on street tires unless something is wrong with their car.

Even my old '96 LT1 and my '03 Volkswagon GTI beater can spin em in first gear.

how do you think its harder to spin with 410 vs 342

when i had the 3.08 gears in my 94 s15 it would spin the crap out of the 32's i had on there. When I went to 3.73 it would not do it. i now have 31's on there and the street has to be wet to make it spin them. I also installed a torsen carrier when I went to the 3.73 instead of the open diff. that may just be the diff

My V6 will spin first, so will the T/A... Both auto. The T/A has 3.08 gears also and will spin all the way through first and maybe into second, I haven't driven it enough to know if it will spin into second, I always let off.

Higher tirespeed vs rpm with 3.42s vs 4.10s.

Don't want to hijack but what you are saying here is that with the 4.10s vs the 3.42s that the 4.10s are less likely to spin due to the tire rotating much faster at lets say 3k with the 4.10s as opposed to the 3.42s? So would 4.10s in a m6 car dead hook better as well or would it cause more spin? I always thought it would spin worst but maybe I thought wrong. I'm trying to work getting my 2.2 60ft times down and have been avoiding gears so I wouldn't have to relearn right now lol.

I don't understand how you can't spin either. I have an 01 a4 with 2.73s, and it will roast the tires. Especially when I had the stock 245's on there.

for 1 yes its normal not to spin the tires with you're not dropping the clutch if u slowly drop it be ready to have some deep pockets to get a new clutch assembly ( so just bring ur rpms up and drop it if u want to keep ur clutch not toasted and stuckto yor flywheel). it is easier to spin the tires with an automatic as they just mash the pedal vs we mash the pedal and drop the clutch at say 3300 rpm -3500 rpm and watch your tires scream to hell and back . much luck on your new ls1 and with the 4.10's you need to drop it at a higher rpm to break those tires loose vs stock gears and stack tires ( just remember the stock diff. is a.k.a names the glass jaw)

You actually have it backwards. At 3000rpm, a car with 3.42s will have a higher wheel speed than a car with 4.10s. For this reason, sometimes it is easier to hook a 4.10 than a 3.42. I wouldn't say that the load is "lighter" on the engine because it's not, but if it's recovering from a bog condition it will be in the low RPMs for a shorter period of time with the 4.10 gear, this is just one way to look at it.

un17real

well put +1 rev up and drop her and hold the pedal through the floodboard and slam that clutch down and shift bam you just raped your tires

Rocweiler

Thank ya sir very helpful. I do tend to either spin or bog and the bog takes a long time to recover from as is. Could launch smoother from a lower rpm with the 4.10s, since the car would climb back up through the rpms quicker. Atleast thats what I think you're saying. Although I would think that would in turn make it easier to break the tires loose since the rpms would be climbing closer to max hp/tq while the tires are still rotating at a lower speed? Appreciate the explanation I never really looked into gearing too much.

question, is that rolling slowly and giving the car enough throttle to downshift from 2nd to 1st? or keeping the car in 1st already?

My heads, cam bolt ons C5 barely spins first gear with stock 3.42's as well. It hooks and goes. I can get them to cut loose if i want them too but i try and get it to hook
