HSW Nitrous Kit for G8 GT/GXP

['02 ws6]

Haven't seen this on here, unless I missed it, just letting people know there's a specific kit out there for those who don't like Zex much.:woohoo:

If I hadn't have already pieced together a kit from left over Nitrous Outlet parts, I'd be looking into this for sure.

[It's A G8!]

This looks like a great kit. If people are getting 150 rwhp from a blower can this car take a 150 shot of juice?

I'm saving my dough for Livernois

With the right tune, yes you can. That's the route I'm taking.

[GRRRR8]

This is a near future upgrade or the new NOS plate/drive-by-wire system.

['02 ws6]

I haven't heard of the NOS kit. Got a link to it?

What about the motor? Can the bottem end handle a 150 shot? More so can the fuel system handle it? Does the L76 have 40 LB injectors?

[Atlas]

my guys say the fuel system can't handle much more than a 100 shot...

[locrzn#92]

The bottom end is not a problem. House of boost made 640 hp or so with 14 lbs of boost and thats much harder of the motor the 100 shot of nos. Its gonna handle it fine.

['02 ws6]

The stock fuel system amd bottom end can handle it.

[wreckwriter]

Bottom end yes, fuel system maybe. I strongly recommend you have a fuel pressure gauge before trying any power-adder.

['02 ws6]

Agreed.

[Mlozano]

Thats a universal 92mm LS2 system that also works on G8, also that's the 92mm kit, i believe we have the 90mm TB, is that correct?


EDIT: yes we need the 90mm kit

39lb injectors.

[shane]

this is the one that will work with stock intake..

spotted it a few weeks ago.... been debating

Debating!

My WS6 could handle a 150 shot on my TNT kit with an upgrade to a 255 fuel pump and a hot wire kit. So I wouldn't see why this motor couldn't do the same with ease. The rest of the drivetrain may be a different story.

Because there isn't a fuel pump upgrade available yet.

It might handle the 150 with a BAP but so far no hardware pump upgrades.

Okay, didn't know that.

So if you can squeeze out 650 rwhp with a boosted car with a stock fuel pump then why wouldn't work with with 150 shot?

Is the BAP an inline pump or does it just up the voltage to the pump when you need it? That's what my hot wire kit does.

BAP is voltage booster, like Hot Wire.

Well another idea would be to add a stand alone fuel system. That's what I am doing to the WS6. I have only used 100 shot after I did the H/C swap and I am worried about the pressure dropping with the spike on the initial hit of the spray. I am stepping up to a 408 so I am looking into a stand alone so the intank pump only has to provide fuel for the motor and I can use race gas for the spray.

That's a lot of extra hassle. I would try it with the BAP first. Supposedly there are several fuel pump options coming.

I already have the hot wire kit and a Walbro 255 pump now.

The stand alone sits under the hood and wouldn't be hard to install at all you need is a power source and switch for the pump and run the fuel line to the fuel solenoid on the kit and you.re done.Well that is the simplified version. There are other little things you will need. It would be less complicated than installing a meth kit for the boosted guys IMO.

Just thinking of the tank/cell for the race gas.....

No just a small tank with a pump/regulator that goes under the hood. Harris sells them for F-Bodies and GTOs. They also have a universal system as well.

Here is the one for the GTO.

Other companies make them though.

[wreckwriter]

Interesting. If its any bigger than a matchbox it wouldn't fit under my hood :)

[1orangews6]

It may be a problem for you but it wouldn't for those that don't have a centrifcal blower under their hood.

[Mlozano]

So the end state?

150shot = no problem on vehicle with no other crazy power adder?

good luck changing plugs Wreck

You can run a 150 wet shot fine with no other fuel upgrades needed.

[Mlozano]

Do you guys think that the smaller UDP will cause lower Fuel Pump voltage?

+1 for BAP

EDIT: + Bap = 1/2 the cost of stand alone fuel system

[breakinparts]

i'm probably going to do this. I think it will be a nice stock driving setup. I'm sure I could hook at the track with my 275 et street radials too.

[Robert@KBXPerformance]

Why does HSW have a WOT micro-switch in that kit? Those are usually used with the older TB's with a throttle cable. Some people do put those micro-switches under their gas pedal but I do not suggest it in a TBW vehicle where sometimes pedal position does not 100% reflect throttle position. It would be much better to get a potentiometer-type WOT switch that can read the rising or falling TPS voltage (depends on what wire you opt to tap) directly off of the TPS. I also suggest using a RPM window switch too.

That kit is really universal, it's not specific for the G8 but it will work, they sell a microedge controller that will take all the electronic TPS, RPM, and A/F signals.

Pretty much all nitrous systems are universal, with the exception of plate systems that use specific spray plates and a few other examples. Still I think it is not cool for a place to market a "G8 kit" when it is not truly made for the G8 because not all components will work for the TBW that the G8 has. It can serve to mislead those who are less informed on how nitrous systems should be configured for the G8's.

[Mlozano]

Very good point

[SFC]

So what was the consensus here, a 150 shot is do-able WITHOUT a BAP?

[MoonRunX]

no, i am not trying to go competition with this car, i just want to have a TT system on it top have some fun and compensate for a V6 engine. Thanks for all the help so far.

[wreckwriter]

A definite maybe. Just put a BAP too to be sure, they're reasonably priced and easy to install.
