If you hold the button for "I'm not really sure, probably between 15-20 seconds in 5th on the highway"

You will end up with this, as well as other minor things like a blown HG and a partailly messed up cylinder wall.




Every other precaution was taken, running a 100shot w/window switch, wot switch, and even a fuel pressure cut-off (not that that will always prevent anything, but it is slightly good measure)

 

Naws is not a good idea on the Highway.
Good luck with the repairs!

 

ouch


Yeah, there's no reason to be using nitrous on the highways. Especially in any gear above 3rd.

 

Ouch!
Were you running a UTEC or any other type of engine management?

 

do you mean start spraying in any gear above third?

 

Eeeww

 

the problem was you were spraying in 5th. I never spray past 4th unless in at the drag strip then its just a lil bit in 5th. The problem w/ spraying in 5th is its just too long and putting all the pressure on the motor for that long ALWAYS=bang.

 

Nos= Fail

 

It was a customers car, the part in parenthesis was me quoting him. It's back on the road already, no naws though, he's skeared now!

 

Yes. Do that. Always.

 

i was asking if he ment never start spraying in any gear above third or if he ment that he sprays from 1st 2nd and 3rd and not the rest

 

Did this customer of yours just fix/replace everything with stock parts or did he upgrade? If upgraded, what parts did he use and why? Adding in prices and down time would also be nice.

 

So basically highway runs is a no no for N2O??? I usually let off after 4th gear anyways when i raced....is that good if you're bottlefed??

 

never touched the stuff, never will, just dont trust it, thats all....

 

Thats a shame...Personally I don't see anything wrong with using N2o under the conditions that you have respect for the product and know the limits of your vehicle.
With that being said, taking full safety precautions is a must to include knowing when it is safe to use it.
So, I don't feel bad for the guy because it is a good lesson learned.

 

Couldn't of said it better...even though my setup was for drag racing I was doing fine in the 1/4 mile until I shifted to 4th (5AT) and took it to 7k and boom.We were trying to get into the 10's with the first stock internals/5AT. But thats how we roll at PF. I can't wait till the built shortblock is done but no more 75 shot just a gentle 35 shot from now on.

 

How did Jeremy do his nitrous shot when he ran the 10.4? Was he not spraying for the duration of the entire run or did he only spray in specific ranges, gears, time, etc?

I recall reading that he only sprayed it in his last gear, but I could be misremembering things.

 

Most of the guys that JT tunes for N20 and are racing, are using the UTEC. IIRC he sets them up to spray between 4k-6500. I'm not sure on his 10.4 run but I'll find out.

 

Ya coach but you and PF are just sick and twisted Wish I lived closer to you guys but then the wallet would be much thinner lol! Nitrous is very fun and safe if you are smart about it. As with all forms of FI, you cant go around boosting/spraying all the time unless you are built; gotta be smart and save it for the pesky domestics and the bpu supras (and the track of course)

 

you can use the bottle in 5th gear.
