You will also have to pull a few degrees of timing out as well.

When you get into electronics for nitrous the price can go up. what year car do you have, and what does your current ignition system look like?
Hi Sigforty, my vette is a '75, and all the ignition is msd ( pro billet distributor, 6al, advance timing control).

Guys I like all your answers, and I think all of you have the right solutions.
I suppose to go low 12's with slick and 3000 rpm stall converter, and I suppose with 100 hp shoot to go high 11's ( what I need to run 12's cat, in an easy way), for this reason I'm looking for this kind of answer.
A lot of people suggest forged pistons, and here I ask you your experience with hypereutectic piston because you, in drag race, have more knowledge that us (Italy).

Thanks to all, for your experience !

I think if you are running a 170 gph pump right now you should be able to support it as long as the feed line to the pump can handle it. Additionally, I prefer using a lower fuel pressure with nitrous as the fuel jet sizes are not as small as high pressure applications.
I am running a hot rod A/C system, so there is some room in the front passenger fender area. Although, I do currently have my MSD Digital 7, and fan relays mounted in that area. I should have mentioned that I considered the storage area behind the passenger seat. I'm not sure if I want to give up the storage. It's sort of a toolbox and spare parts storage area.

I'm running a 1/2" stainless hardline from tank, and a fuel pressure cutout switch. I find it tough to shift and hit the button on the t-handle. I have a micro switch set-up so it can only come on at full throttle. I've only hit it a few times in 3rd gear. The 100hp shot is to much for the lousy BF Goodrich tires. Detuned I'm at 620 hp 600 trq plus a 100 shot (720 flywheel). I'm ordering some drag radials tomorrow from a local speedshop. If something breaks, I'm not worried. I've had a great summer crusing.

Thanks for your input, you also gave good usable advise to Mr_hd too.

You should be good off with all that stuff.

Glad to hear you are getting some drag radials. I personally keep a stock of a few tires for my Z06. I have ET steets, ET street radials and regular everyday tires. It is amazing how different each set is from the other. I hook 692 rwhp in the Z06 on the Et streets and the ET street radials. 73BLWN it definitely pays to have some good electronics when using nitrous. I am personally a big fan of the FJO mini controller, but not sure how well it would hook up to an older car. It is a all in one progressive, window switch, and delay controller. I personally do not run a FP safety switch because I have encountered too many that often do not function properly. I instead have an A/F gauge in the car I monitor as well as FP gauges.
