I am not to sure but I have basically the same car as you except the i have 4.11 and a aftermarket fuel pump and 24 pound injectors and i ran with et drag radials a 12.8 @ 107mph and thats spining the whole time. I would defintly look into the fuel pump and injectors and switch ignition, that helps alot too. All I had done with ignition is a new msd distributor and coil, buts thats all.

24s will do fine with 300 at the wheels. But not being able to give yourself more fuel pressure is hurting you.

I think those are pretty decent numbers. The best ive pulled so far is 13.70@107, with some traction issues.
You dont need 30# injectors for the hp your running.

before i got my 255lph pump i was running almost the exact same set up as you but with afr 165's and the stock cam instead. i got a wide band o2 kit and found i was running 26:1 so i upped the fuel pressure. no matter how high i went it still was running about 20:1. thats when i got a new pump and had to put the fuel pressure all the way back down so that i could run 13.5:1. in other words, that stock pump is causing you to run lean and loose tons of power. you may not have pre-detonation, i never did but i was super lean. get a 255lph pump and a new reg. and youll notice the difference.

also its a convertable so its going to be heavier

Definitly needs more fuel....and some tuning. You'll get that thing running awesome, don't worry.

i had this same problem except my car would only go 14.1@98 i swithched to a 190 lph fuel pump and the next weekend went 13.3@105 with a much worse 60' time. I would change that pump out asap.

where did you run? lapeer is notorious for bad mph

anyways....i think your close actually....w/ a 'vert

i weighed my old '90 lx 'vert w/ me and 1/2 tank was 3600 lbs ....and 3.73's and 100 shot it went 13.60's from a 15.10 pass same day NA

so your looking at about a 140 hp gain from your stock times, of course some of it gearing and traction, so a little less....but all in all...not far from where you should be. i would guess your combo good for 12.80-13.0

and remember what was your 60' like b4...more hook can be less mph

Click to expand...

i went 13.7@102 with a bad converter at milan, then the 13.2@102 at lapeer
Im putting my car on a major diet this winter
yes lidio at alternative, im 5 minutes from his shop.
60 foot was 2.24 when i ran the 13.7 NOT spinning the 225 tires in the rear due to the converter, at lapeer i cut a 1.9 on the BFG's

i guess it def. makes sense that that i would be going lean on the 88 lph pump, im gonna swap for a 255 this winter and a whole bunch of other stuff (ignition,roll cage,bottle,etc.) i just wanted around the mid 12 area on motor then spray the piss out of it... well see well see
