Well I went to the track today with a buddy of mine... Ran my car tiwce 15.67 @89mph and backed it up with a 15.62 @88mph...

Well now comes the bad part. My buddy has one of those "gym bag" nitrous kits that plugs in the cigarette lighter. So i said "what the hell" lets try it. Hooked it up with the 75HP jet and ran 14.99@96mph only to throw a rod at the end of the track

I'll get some pics tomorrow...im too pissed right now to even look at the car

 

Wow, that sucks.. you DID retard the timing a few degrees before running it, and was running 93 octane, right?

 

Had Sunoco 94 in it plus octane booster. Didn't retard the timing though, but i didn't hear any detonation just the rod giving loose at the big end.

 

you're running those times on a stock cam?? that's some good times! that's just about a tenth slower than i ran today at the track! i was running 15.5x. how much is your TB bored?

sorry to hear about your experience with the nitrous. i thought about trying one of the bags one time and i was scared of blowing my motor up so i didn't do it.

edit: what kind of 60' times and 1/8 mile times were you pulling?

 

60' was 2.02 and the 1/8th went by in 10.21

 

Quick 60'! I got a 2.3x best on my 2.8/T5 - one wheeled wonder

 

What are these gym bag nitrous kits? Do they have their own fuel source or tap into the car's fuel?

EDIT: quick research shows... bling bling. No fuel management. The kit expects the car to compensate on its own... with a 75hp jet, anywhere from 30:1-20:1 afr depending on what RPM you were at per given moment. Of course it blew up.

 

sorry to hear, blowing my engine would really **** me off (when i actually did blow one, it simply scared me)

Well, I'd have to say that depending on how nice the car's looking, and how much you like the vehicle, this would present the perfect time to build something better, bigger, and stronger. If you're runningthose times w/ a mildly modded 3.1, your times on a slightly modded 3.4 should be awesome. I'd say, find a 3.4L, add a nice cam to the mix, take all your intake setup along w/ exhaust and place it on there. And once you get over the fear uve probably acquired for nitrous, a 50 shot should finish things off.....just do it the right way.

 

Naaw time for LS1 power

 

if you're serious about switching to ls1 ro something other than the v6, i'm interested in you throttle body! question though, how did you pull a 2.02 60' and only a 10.21 1/8 mile? i've never gotten a 2.02, my best is like 2.05 but i run the 1/8 in 9.5 seconds. when i had my stock 3.1, i ran 10.6x - 10.7x 1/8 with 2.37 60' all day. now i've got a stall convertor infront of my auto and behind my built 3.1...with 3.73 posi rear and 235/60/15s

edit: just saw that you have a 5 speed. what rpm are you launching at?

 

if ya gonna use nitro, be smart or you WILL blow the motor.

 

Anyone got a link for this gym-bag-nitrous-system? Or is it that Sneeky Pete setup; I think NOS made it?

 

Its made by Compu-car

That's almost grounds for a law suit without a big bold disclaimer. You can't trick a car into cold start mode without taking it out of closed loop and defeating the O2 sensor, and EVEN then the O2 sensor can't compensate for 50+ hp of nitrous on its own, and neither can a "cold start mode". Honestly, though, Whitepower, I don't mean to be cruel, but it has to be said for everyone reading this... this is what you get for using nitrous without having a damn clue what you're doing or how nitrous (or your engine management system) works. Next time, do some serious homework first and use a wet kit.

 

OMFG. I can't even BELIEVE that!! Yes, dude, you went WAY THE HELL LEAN!

Tricking the computer into 'Cold Start' mode, will give you like 1-3% more fuel, but you added about (on a 75 shot) 50% more *air*.

Yeah, your optimal 12:1 a/f ratio, went somewhere around
50:1 - 50:3 at best.

Real sorry to hear that... You'll probably find the piston is ok (we've got some beefy pistons stock) and our rods are forged, so hopefully you'll just need to recon the rod, and new mains/rods - then try a 75 shot with the appropriate amount of fuel

 

Yeah, just like I said... 50:1 - 50:3 Completely not cool.

Jesus H Christ. By the time the O2 sensor reads *WHOA LEAN!!* IT'S TOO FREAKING LATE. YOU HAVE ALREADY GONE LEAN!

That's like a bomb going off, and someone walking through the wreckage, going 'A bomb went off!' No friggin' duh Captain Obvious.

 

Holley does make a dry kit for our cars but its only a 65 shot kit. It work by over loading the fuel regulator. It uses a return line restricter. So the regulator tries to send excess fuel and PSI to the tank but it blocks it off and forces it to go through the injectors.

Though wet is more fail safe.

Here is a similar thread when a guy did the same thing on a 75. As he shifted into 5th at the end of the run the motor grenades into a 1000 pieces. It looks like he used a 250 shot but it wasn't.


A 75 shot sounds tame unless it set up wrong.

wow you used that kit and knew little about what you needed to? N2O IS NO TOY in my opinion your ucky all you lost is your car but good luck on the rebuild

 

100% failsafe against this, anyway. A wet kit, when set up properly, adds the exact amount of fuel required to balance the nitrous oxide... something a dry kit has a snowball's chance in hell of pulling off perfectly.

 

... ... holy hell.

 

that was taken from their FAQ pages, definately a lawsuit

 

wow smurf and i'll bet you thought i was a little slow haha

 

Dayummmm.....looks like world war 3 went off in your oil pan! Impressive times though!

Still waiting to see what you can do with your Turbo charged V6 Doward.

 

The pics I posted are of that motor.. since the image hosting died on them and I managed to track them down, I felt posting them might be a good idea for future reference.

 

i saw that post too smurf, but i didn't care enough to track down the pics, but thanks i did wanna see them, yep that was a saturn
