what do u guys think my vert will do, its street mild rebuilt ported , but with all the stock stuff back on, its got the header cat back also, 255 fuel pump stck injectors back on, and thats about it . tell me what ya think.rx7fromcal

 

In a 1/4 mile? Unless you've torn a whole bunch of stuff out, I'd figure right around 16 flat

 

Well whatever it does it will do it better if you put the stock fuel pump back in.

 

why would it do better with the stock pump, i have the 255 in because of the nos hook up.

 

bad thing about it i still havent got the dam thing running right, its going to the dealship on tues, i just cant figure this thing out.

 

The 255 might outflow the stock FPR and cause higher rail pressures, so it'd run a hair rich, but nothing too bad.

 

hey man do ya have a idea of how much hp it may be pushing with what i have???

 

maybe 160whp

 

i can live with that, add what the 75 nos shot , thats respectable.

 

Not "might" and not "a hair". Seems crazy to lose power through overly rich mixtures most of the time just for the occasional hit of nitrous.

 

I'm just regurgitating what I've seen, I've yet to see a 255 change the AF/R's any more than .2:1 on a stock setup, that's not exactly what I call overly rich. But then again, a lot of cars are different so who knows, but that's what I've seen after watching the wideband after swapping pumps.

 

Maybe on a Turbo, but the NA has a lower performing pump and FPR, so the difference will be greater.

 

That was on my NA. '87 Sport to be exact, was in the process of throwing the turbo on it and had started by putting in things that still left the vehicle drivable, and that was one the things I noted simply because a lot of people ask about it. But you are right, they do make it run richer, perhaps on some cars it's worse than others (specifically cars with dirty injectors/etc) My rail pressure changed roughly ~2psi between the two.

 

Besides the fake horsepower (NOS) and lambo doors, car looks pretty clean. In perfect conditions and good driving, I say you can do mid 15-16 sec. in 1/4 mile.

 

Not this retarded crap again....

Hey man, opinions are like ********, everyones got one.

 

let the nos go man , lol ya its cheap power, lol call me a tight *** ok !!!!!

 

haha, sure.

 

hell i still need to get the dam thing running more then 10 minuts , plus the cheap power **** isnt even hooked up , its just laying on the side of the fender well , lol

 

Doesn't mean you've got to go throwing it around....

 

Likewise

 

Mine wasn't an opinion.

Saying nitrous provides 'fake' horsepower, IS retarded.

It just looks like power, but it really isn't....

 

Next time your in MA, let me know, we can discuss this over some brew.

 

My carry permit isn't legal in MA, so I'll pass.

 

hey sonic, well i put the flat head in the afm the thing fires right up, but still has crappy idle, so with having the screw driver in the afm,whats that telling ya??? i have sprayed carb stuff all over and know difference. so tell me what ya think. thanks
