Hey guys I have already (waiting to be installed) the tr224 cam 112 LSA. Z06 intake and hooker longtube headers with off road pipe. No cats. If I dont run out of money I will have stage 3 heads or 12 bolt installed all at the same time. Currently I have just the lid, short stick, and ftra installed. I have a 2000 SS M6. Will I have problems with the Venom VCN2000 kit? I think it uses the readings from the cats correct? If so I cant use my Hooker LT headers because the cats will be eliminated. I just want to know if I will still be able to use the kit. I am wanting to use a 75 shot max with it. That should be enough for most around here. I need a mid 11 second run to rule. Thanks,

 

It takes a reading from the O2 sensors. You can eliminate the cats and it should work. Your main concern will be injector flow. Make sure they can handle the TOTAL hp you will expect to put out. An injector and pump upgrade may be in order.

 

i would like to know more about that system, how does it know how much fuel to add? aren't our o2's inacurate in a rich condition, i can see using the 02's as a back up to shut of the nitrous if it goes lean.

how does the venum computer know if you have bigger injectors.

Thanks for the info. I will start looking for an upgraded pump and injectors. What size injectors would I need to put a 150 shot through there. I hear that venom 150 shot is not quite the same as 150 from other wet kits. Any good ones and where to buy for the best price. I found the kit for 1010.00 at a dealer so thats the best I have seen for the vcn2000 kit.

 

ssdungeon,

Would you mind sending me the info on where you found the Venom kit for $1010? Not sure if you can post it here, if not, please email it to me at timkihm@hotmail.com <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />
TIA.
Tim

 

emailed ya! timkihm@hotmail.com. Let me know how your setup turns out.

 

ssdungeon,
I didn't receive your email. Would you mind resending? Thanks.

Due your self a favor and STAY AWAY from those Venom kits. They WILL NOT work well for our cars. They rely on using the 02 sensors to determine rich or lean states, and we all know that Fbody 02 sensors are not known to be accurate to the point where you can tune N20, Forced Induction, or even agressive H/C setups.

Also, the way it adds fuel is by modulating the pulsewidths of the injectors competely independently of the car's computer. The injectors were never designed to operate in this manor, and who knows how easily the Venom computer could push your injectors over their max duty cycle. So in this case you need to upgrade your injectors ($300+). At the best case you have like a $1300 dry N20 kit that you basicly could have assembled from a NOS kit for about $700 dollars AND got a 15lbs. bottle with it.

If you're willing to drop $1300 on a nitrous system, go head and get the TNT F2 or the NX MAF kit and pimp it out with a bottle warmer, and the Ramchargers timing computer. You'll make more power with a MUCH larger margin of saftey.

Although the O2 sensors are not good enought to tune with, they are accurate enough to tell rich from lean at WOT.

The pulse width is not "completely dependent" the system is monitoring your current PW comparing that to your thottle position, N2O %, and RPM to come up with a new fuel map and PW. There is a reason it cost over a grand! Venom has spent many hours with a LS1 on a dyno with a EGT and wideband. They know what they are doing.

I have attempted to run a 150 shot but do get an "O2 error" - system shut down (engine/damage saved). But I can run a ~140 shot but it seems to brutal for what I am will to put the car though. Running around town with it is nice because I can leave it in Linear mode and have HP on demand.

Times below are with a ~110 shot, no stall, and an A4 with shift issues. Looking forward to getting my 11 second timeslip soon.

I have been running the VCN 2000 unit since July and, although my car has run some low times (10.30), the system completely failed to operate at both the Jet Car Nationals and Super Chevy Show. The frustrating part is that the display says the system is active, but it does not activate and release gas.

Venom 2000 has certain features that do not seem to be designed for high NOS % (60-100%) or all-out drag racing.

Hopefully, I did not kill this thread.
