[turbo mike]

any updates on your setup, or anyone elses?

right now im sitting between nitrous or boost...waiting on one thing, then ill know for sure what way im headed.

[NitrousVR6]

well i should have mine squared away by this spring for sure, im going to the track on the single fogger to see how she does. well see.

[VR6BOPER]

If I had a choice of the two again I would go Turbo since it obviously has more potential for gains as you know. The $ factor is why I didn't go that route initially.

Again, I am happy with what my puny N2O setup produces, so I can't complain!

What turbo setup are you considering?

[turbo mike]

i had a big to4 on my desk, sold that recently, and may pick up a vortech unit....again, waiting to hear back on a few things to decide.

i love my nitrous, trust me. but id like to explore boost atleast once. my buddy is in the 11's on a vortech setup, so its got potential

[VR6BOPER]

If you can swing the turbo setup I would say go for it! You only live once, right?

[turbo mike]

i know what you mean, but if i build it, id want to build it right, including the trans. we just finished a car not too long ago and its been through 3 sets of gears. finally went with an O2J set and it seems to be holding, for now.

he got the big to4 i had, at only 18 psi is breaking things. i daily mine, so nitrous or a s/c is my best options

[VR6BOPER]

Yeah, I know what you mean. nitrous setup cost was very little at about $1,200 with bottle heater, pressure gauge, blowdown tube, extra bottle, etc.

The real cost was the LSD/PP/FW/Axles/hubs/slicks, etc. at about $4,000.

But without those mods running slicks and spraying 1st gear would be a severe problem.

I guess same goes for running turbo at increased boost pressures without the proper safeguards...

[turbo mike]

exactly. if i wanted to spray out of first and keep it together the biggest investment would be my trans.

id like to see what my friends vrt is making for power using my turbo(my old one anyway) since hes breaking stuff left and right.

hopefully this weekend ill know for sure whats going on.

[NitrousVR6]

im going to play at the track this weekend or the next, ill keep you'll posted!

[VR6BOPER]

good luck!

x2, i wanna see some good times

[turbo mike]

no nitrous for me this year. still watching this thread for updates

[NitrousVR6]

welll i ran the vr6 on a 75 shot, at the 1/8th mile on my bald street tires, did a 8.6@88mph, veryyy high trap, just couldnt get it to hook off the line! Well hopefully i can put good tires on and hit a nice faster pass.

[GTIStile]

thats movin, should be in the 12s with ease, on street tires even

[KnightRiderVR]

thats single fogger wet still? your one of the lucky ones who havent backfired yet

[GTIStile]

i think it still is. i only backfired once with over 500 pounds put through 2 different cars... purely my fault as well

[KnightRiderVR]

i heard too many horror stories ...thats why i always ran a dry shot but my best time was a 13.9 with a 2.4 60' @ 107 (sprayed first )on a 50shot street tires full interior all stock motor .. nothing to brag about but it was very reliable im thinking about spraying again interested in a wet shot just scared of back fire

[NitrousVR6]

what does backfire mean? like blow up or just bACKFIRE life cars sometimes do ?? im kind of confused

[GTIStile]

what he's talking about is a nitrous backfire. opposed to having a backfire in your exhaust, the nitrous backfire comes back through the intake. mine so happened to be a 3rd gear downshift at 70mph resulting in a flame [from the intake boot] up over my windsheild and up onto the roof. completely destroyed my plastic intake boot. i have seen people completely destroy their intake manifolds though

[1.8what]

the backfire is not the nitrous' fault.....i ran god knows how many bottles through my car, never backfired once, jetted wet kit on a dyno by someone who really knew what they were doing, if its done right and you don't downshift and hit the limiter then you're ok

That's not a bad start. Without slicks or at least drag radials, you're not going to see the full potential of nitrous out of first and second gears.

With more traction, you will see your times come down, and most likely your trap speed will get a bit lower as you get more traction off the line.

I looked back at my slips for my 12.7@106 quarter mile runs, and my 1/8th Mile Time was 8.16 seconds and my 1/8th Mile Speed was 85.41 MPH

Keep working on it.

it's NOT the NITROUS' fault, but rather adding the fuel into our intake. by adding fuel to our intake design that is not meant to flow fuel, it increases the chances that the fuel and nitrous do not stay atomized all the way into the head. things like low bottle pressure and no purge increase the chances of this happening.

like i said, it only happened to me once and i have sprayed ALOT. earlier in the day i had closed my bottle and sprayed all the pressure left in the line out of the line into the motor. when i went out that night i opened the bottle again, did NOT purge, and as soon as i tried to spray i got a huge bog and...BOOM, there went my intake boot. no rev limiter, just mis-use on my part, it could have been completely eliminated

[1.8what]

yep, backfired in my RX2 twice and both times were because of my misuse....purging...and jetting on the fuel side

[GTIStile]

cool, just wanted to clear that up that it was NOT the fault of the nitrous that caused my "hic-up"

[NitrousVR6]

mannn i got some concerns, i changed my plugs tonight 3 were burnt and 3 looked new, it is running too lean, well it sucks i need a stock chip! im selling the giac chip asap!

[GTIStile]

which 3 were burnt? what did those plugs look like? which 3 looked new? what did those look like? Take pics of them and post em up

[NitrousVR6]

the 3 burnt were closest to wherw the nitrous sprays into, my problem is running a giac chip with nitrous isnt too safe im getting a stock chip tommrow. as for now i replaced the plugs tonught and all is ok i suppose.

[GTIStile]

what was the coloring on em?

[cx96vr6]

for NoS what kind of chip are u guys running. i planning to go the same route with gasket match head, 268 cam, 2.5 exhuast, etc., with 75 shot.

[VR6BOPER]

stock chip for me...

[turbo mike]

giac does make a nitrous specific chip if you guys look for it. adds extra fuel, does nothing with timing iirc. that may save you already with your issues on your plugs.

[jaw0885]

So i have a 2001 12v VR6, with 65000 miles. I am considering putting in NOS but am worried about blowing my engine. Its completely stock, only thing different is the exhaust. What should I get thats safe, and wont blow it? 50 or 75 shot? Wet or Dry... any ideas or suggestions?bump... thanks it sounds good. what do most people on nitrous run in the quarter mile?

[1.8what]

75 wet will be fine......got some jetting recomendations if you need them
