I have a 95 z with some minor boltons 373, 3000 stall, Drag radials, 255 lph fuel pump, coldair, Lca, and headers. I want to run a 100 shot will i be ok or will i have to pull timing i want run pumpgas 93 octane . What do you think i can run with a 100 and my boltons. thankyou

Your sig mentions a PCMforless tune...if this is correct, you will need to be able to pull timing as the tune has advanced the base timing.

I see no other issues with running nitrous on your car, and a 100 shot should drop your times by approx' one seccond.

The Mallory 685 might be a good bet for you if you do not all ready have a window switch. This would upgrade your ignition system, give you the ability to retard timing, and give you a window switch.

Please let me know if you have any other questions,
Ray

i can attest to this statment above........(2700'DA )
175 shot,NA tune(mistake without a digital 6) the car ran HAAARRRD stock bolt on m6 with 3.73s and Nitto's the car ran 13.6 NA and made 5 11.30 passes then it was OVER hole in the pan!.got the car back to the shop pulled the intake off found metal fragments in the intake manifold,pulled the heads looked in the bores and found #8 piston GONE just a wrist-pin connected to a rod slappin around in there.....sooo from that point on some kind of a timing retard is a good thing!!!!

Depends what you run on motor and if you have traction issues BUT ... That said,

A bolt on LT1 like yours should be a solid mid-13 second car at 102-105mph.

On a 100 shot, you can expect, with traction, to cut it down to mid-12's at 110-115ish depending on elevation, traction, 60' times, etc.

A great driver with a well-setup car could probably squeek some 12.0's out of a 100 shot bolt on A4 car at a good prepped track, good conditions, and good tires.

As for running it on pump gas, since you have a tune, your going to have to consult the guys at PCMforless to see how much timing they added. I have a PCMforless tune for a small-medium sized cam only car (22X/23X, .6XX, .6XX) and their suggestions were to pull 3-4* of timing for a 100 shot. So that gives you a rough starting point. Shoot them an email and confirm it before you try anything though.

And use an ignition box to retard the timing. Its easier, close to the same costs, and doesnt give up NA power like pulling timing from the tune will. I use a Mallory 685 box and have had good luck with it so far. Simple to use. Seems like a quality part. Some people were having longevity issues with them overheating a while back. I use the supplied by-pass connector for 99% of my driving, and have the box mounted in my glove box. When I am ready to spray, I turn the car off, connect the plug, and am ready to roll. Its fast, easy, and convienent the way I have it, but I'm sure its not ideal for some ...

what do you run na? What kind of 60fts do you pull?

No track times yet waiting till we get some good weather.

Moshbmx1 ~ Your in severe need of a CAI, Longtubes, and a Off Road, or even Catted, Y-Pipe. That will really wake that car up big time.

I couldnt imagine running a 125 shot of N20 without an intake and exhaust. It will really wake the car up at this point. Stock Manifolds SUCK badly.

Those are on the list but probably not this year. Spending what I usually spend on the car each year on a bike this spring Cars taking a back seat this summer

Aww sweet. What kinda bike you looking to get? PM me so were not thread thieves. I wanna get a Gixxer 1000 this spring.
