So who's still in the running?

I'm down to 15.4 and still have headers, cam, intake, TBI, open differential, lca's, panhard rod, springs, shocks, struts to go...

I'm still running a cat and smog pump and a motor with almost 200000 miles

In other words, I'm well on my way to gunning for 13's hehe

Next mod, TRACTION!

<==plans to get into 14's on stock engine hehe

 

I would be, but aren't heads outlawed?

 

Yeah.. I vote we change that... heads should be a valid mod for the quest for 13. I know we have that whole, the 187 casting sucks, but why should someone who's putting money into this project skimp on that... I say build the best 305 you can, shut the 350 guys up once and for all. Then again, if done with TBI, we can shut up the TPI guys as well hehe.

 

Is the Yamaha in the running there JR?

 

Well, I think it might be able to pull a 13s pass.











At half Throttle

 

i think changin ghte head rule would be a waste. other platforms make it into teh 13's on stock heads, including LG4 guys. so why woudl you think it takes a head swap to maek a tbi car go that quick?
there are a few goals that i have talked to peopel on AIM about.
1. 13's from stock heads n/a
2. 100mph trap spped from stock heads n/a
3. 12's w/ a 305 tbi n/a
4. 11's w/ a 305 tbi w/ power adder

none of these are unrealistic, despite what it seems liek many people believe about teh stock castings. teh first two can be done. teh second two will require after market or very well prepped heads.
the other thing is that all of those goal srely on a combo, not jsut a set of heads. if you think that a set of heads are the only ting holding you back from a good et, then you have other problems soemwhere in your combo.
i don't really see the point of trying to shut up teh tpi, carb, adn 350 guys anymore. cause anyone who doesn't want to appreciate what they just got beat by are the same peopel taht will make every excuse possible to justify losing to you. i learned that when i started runnign with and beating soem L98 and 350 guys. they woudl say how i must have hidden nitrous, or it was really a 350, or that i "cheated" in some way.
if you wanna go fast with a 305 and that is yoru thing, go for it. if you start trying to do things jsut to impress othe rpeopel all you are gonan learn is that there are peopel out there with a lot mroe money that will always be faster than you.

Thanks for editing my post out, Tim. I really appreciate that.

I guess now that I dont say anything its ok?

15.4? Its respectable, but you have a way to go. I ran that already on a cracked block in 100 degree weather, no headers, no I-pipe. Full weight, including stereo stuff. Lowered. 230 degree engine temp. My 350 ran 14.9 stock, with constant audible knock from 3500-up in both first, second, and third. You'd need .5 second just to catch my relatively slow 350 to 'smoke it'. Chances are, you'd want a full second. If I was you, thats where I would shoot for. Breaking into the 14's (like 14.9) is skimming the top side, not beating most. I think you'd want to be at least at 14.5, that'll knock the socks off most of whats out there, or at least surprise the hell out of them. Thats the whole idea, isnt it?

 

I think the most important thing in learning how to go fast is to learn from other peoples mistakes. I over looked suspenion and its killing me. Ive said before if I had to start over the first thing I'd do - before exhuast or anything short of an open element - would be posi and gears, then some lca relocation brackets and maybe even some subframes. I should be able to cut a full second off my time if I could just cut a damn 1.9 60', but Im stuck with 2.412 and thats killing my ETs.

Theres always next year though. Maybe I'll try to take you up on one of those bets Tim (if my tranny holds out ). :lala:

 

NJ Speeder, I'm just joking around about shutting up the other guys really, its more of a fun deal on our Ontario board, you should visit and see just how different the guys are on their. Even Mark A Shields, aka the post ***** likes visiting us.

I forgot when on the other boards, the guys their take it really seriously and will weasel excuses like there is no tomorrow.

As for quest for 13's, alright, if you say that and the general consensus are with that it can be done on stock heads, then I'll go for it. I'm doing well for a stock TBI motor and I feel its still got a lot more potential provided I start matching the right components.

I'm already doing 92 mph albeit with a 15.6, (15.4 if I sacrifice the miles down to 89-90 mph) but it shows that I got a good power combination going for my engine. She's running very strong despite her age 14 years and 200000 miles.

 

Thats very weird that your ET is lower with a lower MPH. I'd say its bogging off the line (guess).

 

Your quest is fruitless.

Besides its already been done

 

thanks for posting joe's timeslip erik, but what is your point? tha twas with a 125 shot so it doesn't really count for this challenge.

tim

 

Why doesn't it count? Is this on motor only? My bad.

 

I believe the challenge is 13 seconds All motor with the stock heads.

 

how about stock motor with bolt ons only and no power adders im up for that challenge

 

Eh, my old challenge was to get my car into 14's without touching anything internal. ie: bolt ons Almost made it, but then she got old on me. Going thru the engine this winter.

 

I'm not bogging off the line. The reason I had a lower mph was cuz I cut my tire psi from 32 to 28.

 

I'm in for 13's N/A. New times either next wed or 2 weeks from today. I'm looking for 14s with stock manifolds and y-pipe, I doubt I'll get .4 sec from an AL driveshaft, preformer intake, and maybe TBI mods though.

 

LoL, its with the TBI not TPI. Sorry, its more of a challenge with the LO3 engine.

 

I own a 91 305 TBI, It has run a best of 15.4 @88 with the stock manifolds and y-pipe.

 

Last night i beat a civic v-tec(ooohh power hehe) but i didnt get a timeslip. My dad was taping the race until his batter died(arghh) and only got my trap speed of 93, corrected at 95. This is the third time ive been ****ed out of correct timeslips and on my best run the printer for the slips wasnt working, oh well. ANyway does anyone know the type of time i can run at 93-95mph traps, im guessing low 15's maybe a high high 14?
BaCK TO THE point of the matter ive did all this with the mods in my sig. I have not did headers, camshafts or any tranny work sides the gears and posi. Im pretty sure i can break into the 13's but ill probably drop the 350 in by then.
When i get my drag radials i know ill definately be in the 14's

 

Well I'm even closer than before. I just ordered my Vortec heads, Edelbrock Performer RPM Vortec intake this morning. That combined with my LT1 cam that I have waiting should put in the 13's.

Hey they are stock GM heads does that count.

 

Only swirlports. I think im there, today would be the day but mother nature had to screw with me and now the track is snowed out.

 

I know a guy running a setup like that

 

For the most part I always like to up the tire pressure on street radials. By droping the pressure you are causing the tire to arc...therefore decreasing traction. A tire that calls for 35psi, I usually put a 40psi causing the tire serface to be larger instead of lesser. Slade I would try this next year at the track and see how you make out. Radials do not create better traction with less pressure. This may get you a bit better of a time. Don't knock this idea until you've tried it! It works! And has for many years.

 

I run BFG G-force, according to BFG can run these as low as 20 psi I think and still keep flat... I ran them as low as 24 psi and had amazing traction but low mph (88-90). (I pulled a 2.204 60 ft WITHOUT any trackbite assistance).

 

I didn't realize you had BFG's I have heard you can get away with dropping pressure with those, but for the most part radials and dropping the pressure will make you lose traction rather then gain any. I would still try 40psi next year at the track just to compare. I'll be there to witness your findings too. I have faith in ya. You've got that old 305 going realy good thisyear so I can just imagine next year. Looking forward to seeing her get those 13's

Why there you are know

 

I won that race too

Since when did you post here lol???

 

i have ALWAYS had better experiences with traction when i air down a bit

 

I post everywhere now. I use the "View newest posts" Icon to see what's happening in Fbody land. If I feel I have something usefull to say...then I'll say it. Doesn't matter which board. For the most part everyone here welcomes me where ever I go. I must say I am kinda hooked. I enjoy what is here to learn and I enjoy what is here to just plain out laugh at too. Some people here really know their stuff, and then their are some that I hvae no clue where they get their info from. It is like a soap opera almost, who's mad a who, who's helping who???It changes so rapidly. Anyway...You'll get those 13's Slade...You really do know your stuff, so I've got faith in you....The good thing is I will most likely be there to see you hit those 13's with your 305. We will have to party when it happens too. GO get it man!

Keiran

P.S here you go again. I think you won that one too.

 

Geez that's all I need.. an ego boost.. like my head isn't big enough as it is lol...

 

Hey man.....How did my car end up making it into this post????

Ha ha....ya Slade kicked my but this year (Shown in the above pic) didnt win even one of our "TBI" showdowns this year.......but next year will be different, I promise, ha ha

 

I admitt it....it was me.

 

....Keiran....thanks for helping bring back memories of that disapointing in October, ha ha

Later,
Dave

 

LOL. Heck I ran down a kids Festiva, only got to run once, and put a hole in my new rad. It sucked worse for me...you just lost a race! LOL!

Keiran

 

...That's right!!! I totally forgot about the Festiva kid.....now that was something right out of a bad dream, ha ha ha

 

I got the new bumper cover for him, just haven't got it to him yet. I'll have to make a drive to Missasuga soon to bring it to him. Bad dream is a understatement. I felt like a fool, but at least it didn't hit any of your cars. I would have felt alot worse if that was the case.

Keiran

 

Just thought I'd bring this one back up and say that I'm still gonna shoot for 13's on stock heads. I have to drive my LO3 firebird for 4 more months since my engine swap in a week(over winter break) for my GTA didn't go well, so I stole the edelbrock headers and 1.6 RR from it (should've taken the underdrive pullies as well). I still have the stock L98 cam from the GTA. I also have my welder now to play with so maybe I can create some traction due to beefing up the suspension/chassis on the cheap.

 

one of the guys to watch is gonna be deadtrend. i have been talking to him and he is getting a lot done. his LT1 cam is in and he got a custom prom a week or two ago. everyone who has ridden in that car seems to liek the way ti feels. he will jsut have to find soem traction at launch, damn stick cars...lol j/k

No nitrous right? Don't worry, I'm still working on 14's But some day mwahahahahaha

 

sice you can't switch heads are you alowed to port the stock ones? and mill them down to raise the compression?

 

yeah I think that should be allowed, but I'd rather fix up a set of 305 tpi heads which can be found for $50 a set. If my swirl ports come off, they aren't going back on. There's no prize money that I know of for this challenge, so I wouldn't waste my time and money on the stock LO3 castings.

 

thats fine my me what are the 305 tpi head part no.s?
and if i just switched the heads how much would that help? i really want the vortecs but i must get a ss hood first to give me a little more room for the aircleaner. at least i like the ss hood and i hope it has room for a taller aircleaner???...

 

I think madmax said it best right here.

I've got a new car that will be in the works here shortly. It's going to have heads, cam, intake, exhaust and other go-fast goodies; while remaining a 305 TBI. Suspension mods will be present as well as some data-logging equipment. I have lots of money to burn.

 

Im just wondering why keep the stock heads if youre going to be doing all of this work on everything else?doesnt the saying "its only as strong as the weakest link" or however it goes apply here?I know it might make you feel good knowing that you did something positive with the stockers still on there,but why waste all that time just to be held back by something so simple?Hell if youre gonna change the stock cam which is junk,then that makes it unfair to keep the stock heads,even if you do port them.Im gunning for 13's N/A on a carb,but Im still doing it on a 305.And yes I will be changing my heads,hopefully to the W/P SR Torquer 305's.G0dspeed to anyone that wants to do it on stock heads,but have fun looking at the taillights of anyone who was smart enough to do otherwise.

 

I think the idea is to first get the car into the 13's with the stock heads and THEN change the heads. At least that's what I would do if I were in on this project.

 

part of the reason a lot fo guys don't change heads is the cost of them. even a used set of vortecs or WP torquers is still a 400+ dollar proposition.
one thing that i hope to see out of all of this is that the stock heads, while not being too great, are not nearly as bad as the wrap that they seem to get. we will all know soon enough as it seems there are a bunch of guys that look like they may have good combo's going into teh begining of the season.

i can see where NJ and Prevost are coming from,but i personally would just rather dump the extra couple hundred on the heads and get it out of the way when everything else is being done.To me it just doesnt make sense to do 2 big jobs when you can do one and get the whole thing finished.I dont exactly have a garage and everything to do this kinda stuff so to get one job outta the way when i can is a huge consideration for me though.but we're all different in our ways i guess.

 

you're allowed to do anything YOU want

 

Its not too bad to change heads once you've had them off (first time off always sucks), probably a weekend job, at least thats what it took me and my buddy on his LO3.

So really it wouldnt be too bad to just keep the stockers on, you'd just have to buy gaskets again when you wanted to swap them which wouldnt be too expensive.
