ok guys im pi$$ed with my car i got a huge mods list for it

Performance: 305,T.B.I, (5 speed,3:42-1 posi) 10:1 compression, Comp cams 12-206-2, Comp springs,ported intake, ported,shaved, relieved,balanced heads, high volume oil pump, Moroso bump stop, Hedmen 1 5/8 shorty headers, polished and ground throttlebody, Taylor 8MM spiral core wires, Edelbrock strut tower brace,C.E. Subframe connectors,Flowmaster 80 series muffler. removed cat and air pump. removed heater valve, WS6 stering box,14x3 open element, some chrome goodies.

i ran it in the 1/4 mile and my best was a 15.50@99.9mph with a 0.349 reaction and a 2.346 60', i was dissappointed i was expecting faster what can i do next i am a student so money is a problem??????
Chris.

 

In a word... traction. I got 15.8's with my 90% stock everything but my 60 ft's were 2.2 range and I finished with only a lowly 89 mph...

You're definitly making more power hence the 99 mph trap speeds, but I'm willing to bet you're also slipping a lot more hence the 2.3 60 fts...

LCA's and lowering springs with some good slicks should break into 14's good and cut that 60 ft time into the 1.8 range. I've seen cars that can achieve those trap speed in the 1/4 mile that hook pretty well into the 1.8 times.

 

100mph is good for low 14's.

You could break in to the 13's but only with ~1.7 60' times which isn't likely with out slicks or et streets. But hey 1 more good mod(maybe get a different intake over the ported one) and you'll be there.

 

Yeah, don't be too disappointed with a 100mph trap speed. Do you happen to know the specs of the cam you are running? Also what has been done to the heads?

 

the cam specs are 440,440lift 212,212 duration, i believe its a 110 center line i may be wrong, as for heads ther e a stock casting that have been port matched and ballanced, releived , shaved 0.20 down and a full valve job with new guides/seals and comp 90lb springs,
i guess 100mph isnt bad but i was expecting around 14.5 ive heard of basically stock L98's running that i would hope a modded LO3 would come close, no replacement for displacement!!Chris.

 

Yeah ur trap speeds are low 14's easy. You need some good tires and some traction mods. I would get some slicks.

 

dead hooking that mph is a 13.5 or .6. don't try to equate the et to the ***** of the car. ets are about gear and traction. work on them and you will most liekly find soem more mph too. that is obviously a strong combo, just have to take advantage of it now.

Did you change this car to carbuerator, or is it TBI??
If its injected, I'ld say you need to get someone to make you a chip (or make it yourself) 'cause its only getting the stock fuel, air and compensation. With those heads, you really would need to have more fuel in that thing.

 

its TBI,yeah it does need a chip ill say that it dosent like to idle that well, i contacted hypertech and got a forum to fill out with info on the car but i havent gotten around to getting the pcm or stock chip numbers yet, what would u guys recomend for a chip or how to custom burn one, i went and checked a totaled Z28 today and it had a tpi system i may go that route to add some more power/drivabillity, but i know u all dont wana hear that!!!!

 

ok, more than likely the 305 ecm # is 128746.(Thats what the 305tbi with EGR computer is.) Hypertech is gonna charge you at least $350 to custom make you one. Most of the guys in here all preach about making your own chips, while this is nice especially if you plan on tweeking your car for drag runs, if you really aren't planning on doing too much else to your car(in your case, there isn't much more to do), Then I'ld just go with the Hypertech Chip. Just to get the stuff to burn your own chips, you would pay $150-$200, then the hard part, figuring out how to program them and what-is-what. This is where ALOT of time and practice comes in. I just can't imagine trying to figure out all of that stuff to make the car work better, it seems impossibe to me. Its your call, but it won't be easy. Maybe someone on here knows how and will burn one for you, I'ld say that's the best way to go.

 

Also, with a free flowing exhaust my bone-stock 305 pulled a 15.5 @89mph. Sounds alot like what you ran due to the chip

 

i wouldn't even botehr with any of the major companies. the most you will get is a half assed chip from them and they will charge you every time you send it back for more tweaking.
yes, burning your own chips does take a little bit of time to learn adn to get perfect. i see that as a great advantage though. do you feel like calling a company back a dozen times and waiting a week at a time to get a chip that makes the motor run just a touch mroe to it's potential or would you liek to make several of those steps in an afternoon? data logging and home burnign is totally the way to go. i don't burn my own chips but i have watched people in action that do it and they all seem to have picked it up very quickly.
tuning does not come from a sheet of paper, a starting point can, but real tunign come sfrom data logging.
even if you do not want to venture into burnign chips yourself all you need to do is look around and soemoen near you will mor ethan likely be willign to help.

u guys know of anyone who does burn custom chips??? id like to deal with this asap its just consumed me right now cant stand my ET!!!! its embarresing in my mind, im guna do some more stuff this winter the the engine but its minor stuff and as for tuning ill never stop the mods!. and some suspension work will help as well, here is some pics of the beast

Thanx Chris.

 

I burn chips, but I can't imagine the whole reason your et is that high is ONLY because of a chip

 

its not just the chip, traction is an issue as well Aaron but the chip would totally help, what do u charge to burn chips and what info do u need??
Chris.

 

If it is an 88 car then the ECU is a 1228603 only 89-92 got the 1228746 ECU. 88 is much harder to get a custom chip for and most people toss that computer and put the 1228746 in the 88 car.

You really need to buy a cheap laptop and make one of the WINALDL setups to datalog and see what is going on with the ECU and the engine. Those of us that burn chips really need that info to get a decent chip.

 

where do you live dude? maybe someone local to you can hook you up. that is the best way, the data log and chip burn can be doen basically side by side. it will save time and postage. if you are in the jersey area we have a bunch of people who can help.
