But I really like the ASP pulley/balancer combo, that is the only one I would run if I was to run one.
We just put the Alt relocation bracket on there so we'll see if we still can trap 113-115+, if we can not, we might try an ASP pulley to see if that will help, cause eventually I will be running a LW battery.

I had the ASP pulleys at one point but considered them a complete waste of money since they were so heavy. Maybe March has some aluminum pulleys that would be better for those who plan to keep their accessories. For those without the best thing might be the ATI dampener (10% under) and a stock alternator pulley.

We have tested the ASP bal/pulley set up compared to dropping the belt, no better ETs or MPH on a buddy's car with an ASP. And in my 94PPM car I did not see any better times with no belt when I ran the ASP set up. I decided not to run one for now b/c of the no belt we usually run...
And would agree, that an ATI or the like might be worth the coin.

Yes I did have the piggy back version. I did not run it for long.
I saw only very minimal gains going from the stock pulleys (& no accessories) to no belt at all. Maybe only a few hundredths of a second if that. And that was with an extremely weighty 200 amp alternator. I got a bright idea to leave the belt a bit loose so it slips on hard acceleration. I wouldn't recommend it but it was funny to see bits of rubber on the bracket like the pulley had been doing burnouts. LOL!
I'm not sure I like the light battery's either. I ran a dynabatt (13lbs) for a long time but since trying the Optima red top I noticed the voltage is much higher and the car seems to run better. It might be worth the extra 20lbs to leave it in.

How much do you gain by removing the belt? I am hoping to get my POS in the 12.7 range this friday and I may pull the belt off for a run. Supposedly the stock hood is restrictive, so i am going to port out the baffles before friday. I am going to pull the passenger seat, pull air filter (5 hp gain on dyno) and run on skinnies as well. Hopefully that will allow me to get in the 108mph area.

Congrats guys. Highh 11's is sick for a bolt on LT1. I need to get to the track. You leightweight bolt on guys are hardcore. I might be there someday. I'm just going for 12.48's right now. Just need to get to a prepped track and i'll be all set. Not bad for 3500lb 6spd untouched LT1

Well, if it werent for Carolina Dragway running only 1/8th mile last night, you woulda seen those .70's I believe.
Last night's 1/8th mile times:
1.592
7.471
91.3 mph
I friend of mine ran the car (he's 70 lbs lighter than me!) and cut a 1.53 60', but missed 4th gear and coasted to a 7.64/79 mph. Ugh, maybe next season!
im still pretty confused at to what these bolt on's are, like heads and cam, headers back, intake manifold, intake, gears, stall/clutch, ported or upgraded tb, anything else im missing b/c if you guys are running those times on those upgrades then i cant wait to start working.

Stock heads and stock cam. And right now I am still running the stock clutch....
We just backed up the 7.471 with a 7.45 at Shady Side today!!
Guessing RW is at 3052.
My mods are in the sig....
