What ya think of my street setup?

scott5 · Dec 4, 2007

Well i decided to make sure i have some fun on the street as well as at the track so i put A H/C/I on my 95 302.. I went with a holley systemax 2 intake w/ 1" spacer, comp cam .544/.555 cam with pro magnum 1.6 rr's, chromoly pushrods, Afr 185cc heads, 42lb injectors with 76mm mass air, 75mm tb and the foxbody tb setup.. I am either which is probably throw a wet nx kit on it or if i run into money a B&G stage one turbo kit on it, its only a lil 70mm turbo something mild for the street.. What ya guys think? I am hoping for a mid 12 run on motor and high to mid 11s on power adder.

sounds nice you should run low 12s with that set up but with the 42 # injectors that seams like to much for just a 302 i would go with 30 O0 but good luck with it tell us what you run

The 42's will be good when you put the turbo on. But are a bit much NA. 30's with a good tune are great on motor alone.

N/A all you need is 24's

For boost I would do 42's...oh and a "little" T-70 lol.

A T-66 would produce MORE than enough power to split your block right down the middle.

I think a T-66 with a .81 housing would be perfect. :thumb:

with tires, a tune and some practice, that combo SHOULD run 11s on motor...nicely executed setup.

scott5 · Dec 5, 2007

thanks for teh words guys.... i was talking to a guy who does some tuning around my place and he said that the 42s could be taking down far enough to be safe until a turbo/ spray is put on.... MAybe bump down to 36s? cause i do not want to buy some now and have to buy new ones and take it apart again..

I am not trying to be rude but that guy is an idiot.

There is no way even if you back off tons of fuel pressure, the 42's are going to push WAY too much fuel for that setup, period.

You can survive no problem with 24's. You don't need larger injectors for a NX Wet Kit. You could spray a 150 shot with stock 19's if you wanted, a dry kit is a different story.

Ed Curtis made 375 RWHP with a Holley SM2, AFR 185's and one of his FTI cams, I believe his total comp.ratio was 11:1

I know you don't want to have to swap injectors down the road, but that is a part of the game bud.

scott5 · Dec 5, 2007

well if i stick with 24s i will not have to buy a set because i already have those in my car now.. So i will be fine with 24s i thought maybe i need bigger to go with the more fuel added when i spray?

You'll definetly be limited by the 24s especially when you add the nitrous, but you are trying to break a cardinal rule of this hobby.

Do not try and do things cheap. :nonono:

All that will do is cause you to do things twice.

To keep from killing your budget or washing out your motor, keep the 24s on there for now and just plan on selling them, and replacing them later with the 42s.
Its not like swapping injectors is going to be difficult. You pull off the upper intake, take out a handful of screws and they are right there.

Hey 42's are not that bad all he has to do is get the car tuned. period. i'm running 42 squirters on a stock 302 and i mean stock intake to oil pan. A good tuner should be able to solve all of his drivability problems with the 42's. I like to tune my car myself that's why i bought a tweecer R/T, this way making sure I'll be the only one messing with my car. all i did was reduce min_inj_pulsewidth, adjust injectors high and low slope and change my injector breaking point, and i was set with the 42's i see perfect 14.7 air fuel ratio at cruising and a 12.5 air fuel ration at wide open throttle and you can do all of this without having to buy a different mass air everytime.. My mass air is a pro-m calibrated for 24 lb injectors and i'm running 42's so. oh yea i'm also running a 250 shot of nitrous dry this is why i installed the injectors btw. any help i can be of man just let me know....just put the 42's that way you don't have to be swapping injectors for every differnet set up.

His situation is different though. He wants to spray with a WET kit. Also he didn't say he had a tweecer to help adjust for fuel. What I would do is buy the 42#er's but run a MAF calibrated for 24's. Since the MAF controls how much fuel is injected into the motor anyways. This way his injectors will work like 24's until he changes MAF's or gets tuned.. (this is just my theory)

scott5 · Dec 6, 2007

i will be getting this tuned.. I think i will keep the 24s in and run it on the dyno a couple times and see how it works and then throw the 42s in and do some more dyno runs and see what works out better
