: My build with N2o

Okay, so here is what I am going to do for my build (thanks to all that have helped by posting on this forum!)

Intercooler & Throttle body from TimmyC
air intake (spectre)
Nitrous (NX proton kit). I spent some extra dollars to get a remote bottle opener, progressive controller, fuel pressure cut off, pressure gauge, and an upgraded heater.

Also got a wideband O2.

The tuning and nitrous install will be done by Shane at J&S performance in Denver. I will keep everyone posted on the results. Can't wait.

How big of a shot?

Awesome man. Do you have ever any pics of the car? I'm moving to Denver in a few months. I'm from Glenwood springs. Shoot me your number. I had planned to add nitrous to my setup next. After I get this tune worked out.

Dave - I'll start with a 75 shot and work up to 100. I've been told the motor can take more, but I want to keep it somewhat safe.

Airgold - I'll definitely post pics once the install is done. I'll shoot you my number - always good to have someone local. So far, i really have not seen any other STS-Vs around here.

cool, hope the 75 makes 95 hp. i keep reading on l67 with m90s the n20 takes well to fi setups so hoepfully lc3 likes it as well lol

In for results as I have been thinking of injecting some of the giggle gas into my car.

sorry..been traveling of late. The heat exchanger is in, but decided to upgrade the stock pump to the jabsco, which just got late last week. The project is a bit behind and hoping to get it wrapped up next week or so. Some pics (not sure if this will work).

Wanted to share some pics so far. Hoping to get most of it wrapped up this week and then on the dyno next week.

Are you using the stock intake?

I have the spectre intake.

You have any updates on this project?

Yup, do have results and dyno numbers. Work travel schedule has been crazy of late, but I will try to get a write-up and some pics posted soon.

I think every one just wants the numbers. Not hard to post that.

My guess there is a piston out the side of the block.

Guys -

I know this is way overdue (between work travel and kids sports!). However, figure better late then never. Okay, so car did not blow up and actually is doing awesome. I've had the setup for some time now and it works well. To jog the memory, I did TimmyCs intercooler, new intercooler pump, 100 shot of N20 (nx express wet system with heater, remote bottle opener and purge kit), a/f gauge, and a tune. The numbers the car put down are:

without N20 - 437 hp and 364 tq
with N20 513 hp and 515 tq

The setup is super clean - the bottle is hidden in the trunk and all switches are hidden in the console. I used J&S performance in Denver and Shane did a great job - no corners cut. My next steps are (in the next 2 to 3 months) are:

smaller pulley
injectors
meth injection
going back and forth on the headers (need to pass emissions in Denver and need cats) - currently have the borla system.

My only issue with the setup is that I put in a fuel pressure cut-off for the nitrous and that seems to be super temperamental. I think I will install a fuel pressure gauge to be able to adjust it proper during every day driving or maybe even remove. If anyone is in the Denver area and wants to see it just ping me.

Dude get a video of this beast ASAP!!

Tought it would make more Tq. My c5 makes 400hp-375 and a 125 shot made 530-598 on a NA set up. Boosted setups normaly pick up even more.

But still it should feel real nice

No injectors needed to hit 500+ hp at the wheels?430+ with just intake,throttle body, exhaust and tune?don't add up to me.am I missing something?

JB_V

Baller95 -Agreed - i do need to get some video clips. Thinking about picking up one of those GoPros and having some fun :)

1madstsv - I was a bit surprised with the tq number with just a tune, but the N20 did help quite a bit on that front. I think the pulley change might help. And yes, feels great when you get on it. The only gripe is i just replaced the tires and went with all-season (DWS). Good tire, but does not grip well under hard acceleration. I should have gone with summer tires (DW).

2007blackbty - this is with stock injectors. I can try and find the data to see how maxed they were. Keep in mind the nitrous is a wet system - adding additional fuel. Fro the next set of mods i'll definitely be going with bigger injectors.

Did you switch to colder plugs?

Also does your nitrous activate through the throttle position sensor? or a microswitch?

Too bad they didn't do AWD in the V ... you wouldn't have to worry about the tires not grabbing at launch as much :)

JB_V

The plugs are the stock heat range. However, i most likely will go one heat range cooler with the pulley add. The nitrous is activated with a micro-switch placed by the accelerator pedal and will engage at WOT if the system is armed.

I'm doing TC Fab Headers, and welding into my Borla exhaust two SLP high flow cats ($180.00 or so for the pair) and two new post cat O2 bungs into each pipe extending just aft of the stock cats. Just need to extend the O2 sensor wires aft of the new high flows to the new bung location. SLP makes some pretty compact units with heat shielding on top to mount almost anywhere. I'm screwed here with emissions too... Just waiting for Jet Hot to return the headers, and I'll get it underway. I know, overkill because they're stainless, but screw it...do it once, done forever, no regrets...
