First thing, this is the power adder forum, you need to be in the trans or tech forum,

next, there are these things called sentences in the english language. please try to use them.

thanks

True Power

No, seriously, learn to write sentences.

Lesson 1 - the period "." Use it extensively, please

Lesson 2 - some more info on the engine would be incredibly helpful

I'm sorry, about coming off like a a$$hole, I barely passed high school myself and never even took the S.A.T's,

All i'm asking is to please break up your post so it is readable, i have read your post many times now, and i still can only figure out part of what you are trying to ask. I'm not asking for perfect sentences or grammar. just put a space or something after each question.

And I'm sure more people will be willing to pass on their knowledge.

later

Ok we will start all over,I have a 1988 camaro and I went to the track and my 1\4 mile times are slower with new combo.First pass was 13.98 at 98mph,and second pass was 13.54 at 105mph,and third pass was 13.22 at the same 105 all on street tires.Mods list is 5.7L .030 over,trickflow heads,24pound injectors,hooker headers,3200 b&m stall,paxton supercharger 10psi of boost,comp cam 220/230 dur, lift is 510/510 with 114 lob sep. Old setup was a slp cam that was the same as above but intake lift was 502,and the lob sep was 112. The stall was smaller maybe 2400.The old times with that setup was 12.71 at 111mph. You think 24 pound injectors could be the cause.

I see you went with a cam that runs a wider lobe sep. from 112 to 114) and more intake lift (from 502 to 510) and a coverter that runs more stall(2000-2400 to 2800-3200). I am curious what gears are you running? what fuel? what intake? what cubic inches? I have seen TPI blown cars go slower with more converter because of the amount of torque available is not allowed to "grunt" the car to the finish line (that goes for too much gear as well). what may not be too much converter or gear for your buddie's carb and carb cammed 3rd gen can be way too much for a car like yours (I might feel totally different if you were running like a TPIS mini ram, 302 chevy, cam with 108-110 lobe sep, and a vortech YS-trim). what were your 60' times? what was your 60' time on the 12.70 run?

B4ctom1,it is a 5.7L .030 over motor.the 12.70 times was on street tires and 60 foot was the same as new setup 2.043.the tpi is stock.THE fuel system is ok walbro gss340m hi-output with hot wire kit.my trap speed is slower by five miles.i have 30 pound injectors that i am putting in now to see if it will help.or do i need to upgrade my tpi.

kream-

My guess would be too much converter... :lala:
Did you ever mention what gears youre running?

kream-

I would reccomend an intake upgrade for your next mod. Probably Lt1/miniram/holley stealth ram or something other than the LTR setup.

posi

stock,3.23 rear gears

please scan and post old timeslips and new timeslips I can really diagnose a car by its time slip. I have seen many a car go from 12's to 13's just by adding power.

Going to a cam with more lobe seperation (114), and going with a higher stall makes little sense. 114 degree cams (I have one) make very good bottom end tourque, but make less highend horse power. You should run a 108 deg. This could give you a possible 40 more horse at around 5500 rpm. Just my thoughts.
