n20 Questions

[coralcoupe1993]

A friend is bringing his 94 GT over for some power! I have some N2o questions for you. So the car is a stock bottom ended 95 5.0 with about 110 miles but it runs good. It has a trick flow top end, Steeda Cam, 70mil TB, 73 MAF, 24# injectors, 255lph pump, 3:73s, Tremmic, MSD so on and on. The kit I have is the Zex wet 75-125hp kit. I had a few questions for ya..

What plug should I run?
What gap?
Should I get a tune or what timing should I run?
What fuel pressure?

I am looking for some 11s so the N20 is the ticket!

I think you can run the stock 10 degree timing and get away with a 1 step colder plug. I prefer motorcraft asf32c. These are the ones i use on my dry 175 shot so far so great, i'm hoping for some high 12's on the juice of course i hope i can do this. ;D ;D ;D

autolight 24 i figured i would post this before adder flames you about it.j/k run stock timing, and dont spray under 3k it can cause detonation.

gap'em about .030" Fuel pressure...I'd right around 40lbs with vaccum unhooked. You won't need a tune to spray the piss out of it. I sprayed mine with 110k on the ticker for about 2 years....pulled the motor apart and it was still fine.

Hey rycleff i wanted to ask you something because for some reason i can't run a gap lower than a 0.40 or the car will idle like crap and run like crap..... and at a 0.40 and up it feels like 3 times better... .although i just replaced my whole ignition system with msd components and i haven't had the chance to retest with a 0.35 gap any ideas? one other think I got M/T drag radials 275/50r15, and my 175 shot would be possible i can break into the twelves i'm happy with a 12.99 on a stock motor (provided i can grip)???? thnaks

You should be fine....The only problem you'd run into with that big of a gap is it MIGHT blow the spark out...it won't hurt anything, performance might suffer...thats if it blows the spark out. It probably won't though. 12.99 should be easy with what you got.

I forgot AdderMKII is on mustangforums.com.lol. Ry is running a gap of .040 going to hurt my N/A performance at all?

 

[ryclef331]

No sir, it will help more than likely...bigger gap = bigger spark. More area for a flame front to start...

I heard autolir 3923's gapped at .35" is pretty nice on 10 degree timing on 93 octane.

 

[ryclef331]

for aluminum heads....yup. Check out the plug sticky I put up earlier today.

 

[Hybrid Freak]

He said trickflow top end kit. So I assumed it was aluminum heads.

Well just wish me good luck, 12's here I come...... thnaks rycleff331
