You Vortech guys missing that tq??
you should add this to your car!!
first off the car. a Super Black 03 350z that we built this engine a back in Dec. just a simple build, low compression pistons, eagle rods, stock cams, stock everything really. we threw some nitrous on to get it by. Next we added a brand new Vortech supercharger to the equation. we decided to go with the 2.87 pulley and tune it to a safe level. we netted this. remember low compression. also my dyno has been being mean for some reason lately.
NOW for the fun. we left the nitrous on the car and decided to throw a small shot on top of it. while nitrous and a vortech have exactly opposite power curves, we decided it would be a perfect match. WOW, we were right.
here is the start, a small 50 shot. notice 150 instant ft pounds of tq
we now upgraded to a 75 shot but started to run out of nitrous, when you get low on nitrous, it hits really hard then always acts funny at first on the dyno . then it will put out less power than it should until you fill the bottle again. check that tq out..
another 75 shot graph, look at the instant 225 ft pounds of tq!!
here is the overlay of all of them...
now for the fun. we filled the bottle and changed the jets to 100 shot. we didnt feel like putting it back on the dyno. we just took it out on the street to tune it real world. we figure it would put down a safe 500/500 all day long. we have the utec controlling the nitrous, along with a safety switch and a push button. i CANT believe how fast this is, you have the ungodly tq of nitrous plus the top end pull of a Vortech. perfect match!! having the nitrous on a switch will allow you to get normal traction in 1st and 2nd gears then add the extra 100 or so hp in 3rd and up.
Justin will be taking this to the track here soon and see what he runs, i know he will have a lot of fun and put up a lot of videos.
basically this would be a safe addition on a stock block with a 35 to 50 shot. this will provide all the tq you are normally missing under 5000 rpms. we set this to come on at 3000 rpms and stop at 6400. this is a fun way to add onto your Vortech to make it complete...

1st big thanks to Jeremy for trying something new and getting this done for me
I'm picking up the car Fri. so I will have some pics up this weekend and I'll be taking it to the track the 1st weekend in Nov.
again thanks Jeremy, can't wait to drive it now

awesome! thanks for posting. That is a seriously flat tq curve as the nitrous losing bottle pressure is balanced with the vortech's power up high
I've thought about doing a direct port nitrous on my SSV for awhile, (on a built engine since direct port would be be a bigger shot) and having it kick in during 3rd or 4th gear depending on how traction goes
but I've also wondered about running a small 30 shot instead and getting more runs worth of nitrous which would last a pretty long time and help keep the engine cool for having the extra early torque and not running out of bottle pressure as fast.
I think I'd still lean towards a 120-150 shot of direct port nitrous for higher gears though because I'm not sure more power in lower gears will really make me all that much faster below 60 mph without drag radials or slicks

should easily be a low 11 second car with some decent traction. we will see.
yeah guys, give me a call at the shop. we can figure out some way of taking off and traveling out that way. we have a lot of customers in OK, KA, and TX that wouldnt mind us coming over there.
