Those spraying 125+ stock long block come here
 

So I sprayed last night with a 100 shot and compared to my 95 the things nutless still lol. I wanna throw atleast a 125 shot on it if not 150 I just need people to talk me into it ;). I'm trying to sell my 347 and when I do I'll start building a nice shortblock for the 2000. But until then I'm still a little scared to spray that much on a 123xxx mile shortblock

Id stick with 100 man. honestly if you think its nutless after a 100shot then maybe nitrous isnt your thing lol

Planning on running 125 shot....Should be more than fine if you have a tune for it. Are you running a plate kit?

Tim2002gt is running a 125 shot on his stock longblock with longtubes/full exhaust/brenspeed tune for the 125 of giggle, bigs n littles, 4.10s and correct me if I'm wrong but I think hes running between an 11.5-11.9 in the 1/4.

EDIT: I believe he is running a wet plate kit.

Just a nozzle kit. I think it's mostly my stall that covers it up. With the 95 I could floor it at 2800 and feel the nitrous hit at 3k. But with the stall it instantly shoots to 4k so it's just there.

I'm using a nozzle kit also. Been doing it for over 3 years and it still runs strong. I'm aproaching 120k miles too.

Your not going to be blown away by switching from a 100 to a 125 shot, but it will be a noticeable difference. You may have been spinning a little and didn't know it also. Mine won't hook for anything with street tires until 3rd gear on a 100 shot.

Have you had you car on a dyno to check your a/f ratio? If so and all looks good, more than likely all you will need to do is take out another degree or 2 of timing and you should be good to go. Make sure to only spray it in a safe engine rpm band also, something like 3k-6k.

I dont think it was spinning, i have 555r's and tried it out at 20mph in second so it should of been alright and didn't feel like it. My a/f has a very slight lean spike at first which i'm trying to mess with to get that outta there, but other than that it's pretty much right around 11.8 the whole way up which is good and safe as far as I know. I also have a microedge controlling rpms and it activates at 3200-5900 but with my converter it never see's anything under 4k when i'm in it.

I didn't think my tires spin from a second gear roll with et streets. Until I went back and can follow black marks for 1/8 th mile...

At the track you will feel it hook, almost throws you in the back seat. Then you will realize what traction really is!!!

Nice numbers , What was his trap speed ? any clue?
4:10s seem to kill my trap speeds last run I did was only trapping at 100 MPH :( top out in 4th gear.

I looking to change my gears to 3:55 , know anyone in my area that want to swap rear ends straight up ?
4:10s for 3:55 whole axle, Ps mine has a new pinion seal and diff gasket running Mobile 1 gear oil.

Millage is around 30k on gears sense changed from my stock 3:27s

If anyone see this and theyre interested PM me

I'll trade you my whole rear (stock with 55k) and give you 50$, plus do the labor on both cars.

Your doing something wrong to only trap 100 in that cobra with 4.10s. I running 105.5 with 98 and only mod is an x-pipe.. literally, only mod
