Street traction
Here you go fellas, this was on the ET streets today coming home, i mentioned to my buddy that you guys were talking about how bad i spin, well, this is with the 26x11.5x16s that i use for business.
This was 18 PSI on a back road that as you can see in the video, unprepped and has allot of dirt on it, so, it hooks well with tires that aren't old radials.

Re: Street traction
didn't see the nose pop up at all....ditch the front sway bar and try again. My car hooks coming out of a car wash...you need more suspension tuning

Re: Street traction
ya i got PLENTY of friends around here with manual trans, what you're doing isn't something new. lt1 cars, ls1 cars old gen 1 sbc, the nose has to pop up and plant the weight on the rear. Take off the sway bar completely up front and you'll be amazed. This "manual trans" excuse doesn't fly, I had a T5 in the car when I bought it, and guess what 1.5s out of it until it popped. Just takes more work, in your video it didn't move at all, so either leave it or try my advice out and see for yourself.

I understand man, but we are talking different trans and cars, a T5 has a steeper first gear. The cam in my car has NO ***** till 4500, my setup is not set up for any competitive drag racing.
Did you watch my track video? How does that look? The street is not going to allow me to hook on a dirty back road, no one actually, just showing i am not busting tires loose all through 1st and 2nd like the other video.

Re: Street traction
Yea, bet you were launching on the moon huh? I am not dumping at a high RPM, just slipping the clutch at high revs and the once i am rolling out i am going fully disengaged.
I am scared of it breaking the stock DS, so it will wait, i did try 6000 and it still bogged when the RPM came down.

Re: Street traction
i know nobody wants to listen to my advice, but you do not want the manual car to dead hook. thats where everybody screws up their chassis tuning.
i launched mine from 6k and dumped the clutch. i did have a 12 bolt and chromoly driveshaft. my car also did not dead hook.
a buddy of mine broke his 8.8 axle leaving at 3500 rpms in a foxbody with 250rwhp. why did it break? it dead hooked and that was enough to break an axle.

Re: Street traction
you're going to have a really tough time getting a stick to dead hook, and unless everything is bullet proof and the chassis is setup to work that way that is not the fastest way to go. I've had my 4th gen video taped launching and found that I run the fastest when I have about 1/2-1 revolution of the tires before they grab, and I launch slipping the clutch in at about 5Krpm.
as far as gear ratios a some of the 4th gen T56's have the same 1st gear as the 3rd gen t5, and in general, yes, most 4th gen T56's have a slightly lower 1st gear, and most 4th gens are running steeper rear gears making up for that.

Exactly, i have a friend with some MT drag radials i want to try, they might get the right amount of slippage.

I cannot remember what the T56 is but i think it is 2.6 1st gear maybe? The ZF6 speed has the good 1st gear. The T5s usually had the deep 700R like 3 to 1 first, but some didnt, some had a 2.7 or 2.6, i cannot remember exactly which ones, but the T56 never had a good 3.06 or whatever 1st.

Re: Street traction
The later T56's had a 2.66 first, the '93's had either 2.97 or 3.36 first gears, depending what package you got. Depending on which V8 and year you had, the T5 had 2.65, 2.75 or 2.95 first, I'm not sure what super steep first gear you're talking about in the T5... the mustang got one in the low 3.x range some years, and steeper firsts were available but they were only used behind 4 and 6 cylinders (like the 2.3 fords had a 4.05 first gear)

Re: Street traction
^ Exactly, some GM T5s did have a bit shallower 1st though.
