well i got myself a kit yesterday and i was wondering what anyone thinks my car will run with a 75 shot?

 

Depends on the dyno, probably looking around 260-280.

 

What kit did you go with?

 

nos wet

 

on a zex wet kit w/ 125 i ran a 13.6 at 109 and dynoed 298 hp

i dont think the kit works very well and will be switchin to an nos or nx kit soon...w/ a 125 shot i should be in the mid 12s...

 

how reliable is it with a 125 shot?

 

That time tells me you didnt hook up. Your trap speed also does not say mid 12s. At 109 I could see high 12s being possible, not mid. You dont need to switch kits, you need stickier tires. Either some street slicks or a true slick setup and you'd see better results.

 

what im tryin to say is that w/ the zex kit im only pulling 45 hp out of a 125 shot w/ an nx or nos kit using solenoids instead of a brain i should get more actual hp which would give me a much quicker time...and yes you're right i do need stickier tires...looking at buying some 5 axis sf:5's w/ nitto invogen's now...

 

Ah, I see. I dont have any experience with zex, Ive always used nitrous express, so I dont know how the brain controls the amount of spray. I love how the NX was simple, you toss in the appropriate jetting and away you go. I would also recommend a bottle warmer and pressure gauge (unless the kit comes with one). Heating the bottle up with the heater in the car after a pull is kind of tedious... lol.

Why invo though? If you're going for a street slick, why not the nt555? Again, with the amount of extra torque/power you're going to be putting down with a 125 shot, you're going to need a bunch more traction. Also, have you read anything about how safe a 125 shot is on the internals of out motors? What about fuel delivery and spark plugs, have you upgraded those areas? I know you are going to want to go with a colder plug (2 steps colder than stock if memory serves). How well do our motors like the juice? I honestly havent read into it at all.

Good luck though, should boogey pretty nicely if you can get her to hook up.

 

Are you guys retarding your timing back -2 or -4? I thought running anything over 75 on our stock engines was very sketchy.

 

i had my timing pulled 2 degrees and ran 1 step colder plugs before goin to the dyno...after i got my tune they tuned the car in for the 100 and 125 shots...

 

i went to Houston, TX and had the car tuned for the 100 and 125 shots with the zex...i'm running 1 step colder plugs and from what i've read and heard thats fine for the 125 anything more than that and ill have to go 2 steps colder...no fuel upgrades needed up to the 125 shot...

the vq handles the nitrous just fine, but like i said when i spray i only get like 45 hp so then again maybe thats why...

i'm thinking with goin w/ the invo's b/c my friend has a set of 5 axis sf:5's w/ the invogen's he's wanting to sell me for $1500....

heres a quick pic, what do yall think:


sorry for the threadjack...

 

its cool iv been against the spray for a long time but could not pass up the deal and now i know what the can can handle

 

Hey guys

I went to the track last week with my 06 coupe with a dynotune nos kit and test pipes. with a 75 shot on street tires ran a 14.00. Put the ET streets on 1st pass ran a 13.5 back to back and the last pass of the night ran a 13.2 at 105. I think she has a 13.0 in her caus i had to let off in the top end.

 

should i keep it at a 75 or move it up to a 100 the car has 98,000 i dont want to kill it
