so i hooked up nitrous to my 04 srt 4 went out to make a pass and as soon as i hit the switch my 90 degree bend in my intercooler pipe blew to pieces it was made of rubber and oil that has been leaking on it for awhile and weakend it it was only a 65 shot what are my options to fix this problem and keep it from happening again

Sounds like a backfire happened. If so, you need to figure out why it happened. What rpm did you spray at, were u at WOT, is the jetting correct ? Also is your ignition system in good shape and what about plug gap ? Tightening your plug gap a little cant hurt when it comes to using nitrous.

i was at about 2500 rpm wot and everything on my car is in great condition is it possible with the tube being weak and my turbo already making 18 pounds that the extra boost was to much for the rubber pipe i soon as i hit the nitrous it blew and that was the first time i used it i ws only using a 65 shot on a dry kit it was shooting into my intake pipe about 12 inches from the air filter

If I were going to guess. Since you are using a dry kit and shooting it in before the turbo. The turbo isnt at full spool at 2500 rpms, so when you started spraying the nitrous, it acumulated in the intake pipe and then the turbo spooled and gave the sytem alot more than just a 65 shot.

If your going to run that setup I would wait until full spool (3k+ depending on turbo) to start spaying so the nitrous doesnt back up.

If you want to use it to help spool, you should run a wet kit just before the TB.

yes before the tb

lyncoo · 10-02-2009, 10:34 AM

what turbo do you need help spooling

s ar tee 4 · 10-06-2009, 10:32 AM

a dry shot, before the turbo, at 2500 rpms. all of those at the same time cant be good

1st off a dry shot is a big NO NO with these cars! You will not get additional fuel.

2nd, if would be a good idea to back your boost down a pound or so. Because of the nitrous, you are gonna get more boost.

3rd. Do you have a wide band? Do you have any idea what you AFR's was while spraying a 65 dry shot?

Dude, your car is not gonna last long.

yeah 2500 is a little too early to be spraying. my car sometimes didnt even like spraying at 3000....but 3300 and above never had any issues. and unless you are running super rich off the bottle then i would not run that big of a dry shot. Wet shot definately a safer option plus you should be spraying into the cold side pipe after the intercooler.

2500 is too early. Needs to be more like 3000 or 3200 just to be safe. Shoot your spray in the cold side charge pipe, and dont use dry, use a wet kit.

x2 when you spray low in the rpm range (under 3k) your cylinder pressures will spike way beyond what they should ever see (even at max power with a big turbo) you got away lucky if you look at charts of IMEP and BMEP with N2O they can see 2-3x the load when shot under mid 3k rpm's (3k will be OK with a 65 shot) that means you motor may have been seeing the pressures it would at 500-600 hp at 2500 rpm (YOUR RODS HATE YOU NOW)

NEVER BELOW 3K ...OK

first thing you should do is educate yourself on something you know nothing about.65 dry shot? 18 psi? come on...seriously

me thinks the motor will go hand grenade....

lower your boost, wait till full spool ( above 3000 rpm ) get an air / fuel monitor, and get a wet kit. save the motor from the first re-build for a few more months
