Nitrous

[98ciHemi]

I am not really seriously thinking of spraying the Escort yet, but I am kind of curious whether or not I could even consider doing it safely on a stock bottom end. I am not really pushing the limits of my engine combo, and I only have maybr an 8:1 cr.

Re: Nitrous

One wa to find out how much it will take ;D

Re: Nitrous

I really wouldn't push it, unless you have forged pistons.

Head studs wouldn't be a bad idea, either.

Re: Nitrous

Keith's rule of thumb is "No more than 1/2 of the engine's existing power". Seems like a safe bet. My rule of thumb (not supported by Keith) - "Don't turn it on unless you have first put the car on a dyno with an AFR meter". If the engine goes lean the N2O will oxidize SOMETHING and pistons are the second easiest thing in the chamber to oxidize (the first being fuel). Why chance it? Wayne the Dyno Guy and I will look at that before a WOT pass at Maxton, for sure.

He'd be safe with a 50 shot. Lots of companies have kits with small shots for the import crowd. As long as he tested the system before giving it a full WOT pull, I betcha the motor would live through 2x it's original power if he doesn't over-rev it.

We took a stock, cast piston I6 Ford to somewhere north of *triple* it's stock power. We were very careful about monitoring AFRs and I spent a few hours on the dyno before we took it to the track, so I could know where the timing wanted to be... in this case, it was WEIRD timing. The old rule about "remove a couple degrees for every X hp" didn't really apply.

So, Walt, what I'd advise is something simple like a 35hp wet shot. Try it out! if you REALLY want to be safe, find a used LM1 AFR meter for sale somewhere on craigslist, get a new sensor for it (Autozone parts, around $45 bux), and give it a whirl! It's not really as violent as people like to think, it's only when you start pushing things when the engine is already telling you "enough is enough" that you break stuff.

Ask Chad. I still remember the phone call "can you walk me through adding some timing and pulling a little fuel out of this thing? we need fireworks, dude!"

Re: Nitrous

where do you find forged pistons or head studs for an engine ford has not sold in 18 years ?

Re: Nitrous

open the ring gaps is a do- able mod though

Re: Nitrous

What I was thinking was in the 20-30 shot range.From what I can tell, the stock pistons are hyperutectic cast pieces. And spidey, yes they make head studs and Vic Ellinger from wiseco quoted me I think 140 a hole for forged pistons and rings to go with. Can someone explain the difference between dry, wet, and direct port systems? And where would a plate style system fall into this?

Re: Nitrous

have you hit the n.o.s. web site among others..all the info. is there..
you can hit that engine with 250 shot with a progesive controller...
as what kills ring lands is the big hit "shock" and no matter what anyones says(they are not paying for the repairs to fix it, if it goes boom)
run it a tad rich.. yes you'll loose some power.. but you'll not end up on a hook,,
you cann dyno it all day,, play with the timing put out.. all if it..
if the fuel flow slows for any reason..(and there are many) and you're on the razor edge, (to get the most power) it's go lean.. it only take a second to hole a piston...
the handheld d/g talked about is a great idea, but danderous at the same time..as it can make you greedy.. and run to close to that razor edge.. and it can bite you..
just ask anyones thats used it..
we (in school no less) had an 86 escort and hit it with a plate 250 shot.. with a progresive conntroller.. we jetted one jet rich.. and it lived a long life.. (5 bottles worth) you'll find the tranaxle is the weak link ;)

Wet systems administer both nitrous and fuel, dry systems, only spray
nitrous, allowing the fuel system to enrich the engine under spray.

Direct port, as the name implies, is plumbed into the intake port,
and sprays nitrous/fuel directly into the port.

Re: Nitrous

directport can be wet or dry..

I'd read up on it at mike thomus sites
his old company n.o.s.
and his newer one nitrous works

Personally, I don't care for dry systems.
