215 HP TPI vs 170 HP TBI. You'll kill him by a few carlengths.

is that TBI 5 spd or auto? the 5 spd TBI cars ran as fast as alot of TPI auto cars. It should be a good race if hes a 5 spd but if hes an auto u should take him pretty nicely.

 

beatdown... period. Your car is the better part of 2 seconds faster than his in the quarter. 5 speed or auto, doesn't matter... if you can drive, he's dead.

5 speed TBI cars aren't as fast as any L98 cammed TPI 305 car. Still about 1 second difference in the 1/4, at least.

 

a good tune 5 spd TBI car should run a mid 15 second quarter. Thats the same as an L98 cammed TPI car. 5 spd compared to auto is a huge difference. 5 spd cars are atleast half a second faster than autos. There is more power to the ground, they are over 100 lbs lighter and it keeps u in ur power band alot more.

 

BTW to have a car be a full 2 seconds faster than another it takes about 200 hp difference. not 35

 

You're an idiot. Does that mean my T/A, which ran a traction limited 14.9@93, has 200hp more than my friend's TBI 88 T/A, which ran 16.8@85? Do the math... That adds up to 370 friggin HP. The HP difference between cars running different trap speeds and ETs in the 1/4 is based on a curve. There might be a 200hp difference between a 9 and 10 second car.. but there is about a 50hp difference between my TPI T/A and my buddy's TBI T/A.

Have you taken your car to the track? Do you have anything to back up your assertations of mid 15 second stock TBI cars? With a few mods... Ultimate TBI and catback... sure. Stock? nope.

 

actually i had this very race when i first got my car 6 years ago. if the tpi car is just a normal maintenence car the tbi car will win. if the tpi guy cleans out the intake and runners with some spray or something then he will run away as soon as he hits second gear.
for some reaon the earlier tpi cars build up goop in the runners really fast, dunno why. that steals a ton of power.

i really hate people who think they know everything. A tbi 5 spd car will take a TPI auto car. i have seen it.

**** you, dont act like ur the mr ****ing know it all about these cars. right or wrong......by everyone elses theory the difference of one car length is about a thenth in the quarter mile right?? ONE tenth in the quarter mile is equal to 10 hp......right? So going by that theory u can see what im sayin. MRJ i always see u on these boards trying to act like u know everything and u dont. far from it. If i may have made a mistake it was perfectly logical so kiss my *** . 5 spd TBI cars run a 15.5, thats the average for a good tune properly running 5 spd TBI. As i remember u saying ur car ran a mid 15 second quarter when u first ran ur car. remember a TCC is about a .4 second increase in performance so u cant count ur current times if those are indeed after ur TCC. The 5 spd TBI better be a damn good race for a auto TPI. the 5 spd is lighter, more power to the ground and more in ur power band. I dont see how that is so far off. One car may have a 40 hp advantage (or whatever it is) but that 40 hp is cansiled out by a 117 lb weight advantage,5% more power being put to the ground and more in ur power band. So that 40 hp means nothing. If ur so smart and i am such the idiot than explain to me how i am wrong?? no ****ing was will a car with such a small amount of hp more run as much as 2 seconds faster. it doesnt make sence.

dudelovett ur right we have been down there b4, but atleast u were kool about it and werent trying to insult me like this guy is.

 

You're still an idiot. Every one of your posts that I've read proves it. You're the joke of the TBI board, if you haven't realized it yet.

https://www.thirdgen.org/messgboard/...ML/000356.html

as for my times... I refer you to the above thread. And I don't know what you're talking about with your mention of a torque converter clutch, yes my car has one, yes all automatic cars have them. The fastest time I ran was done almost one year ago, on the stock 1600RPM converter, before I installed my rebuilt 700R4 and the new converter.

Lastly, I'd just like to say that I'll believe 'mid 15s out of a stock TBI 5 speed car' when I see it with my own eyes. 100lbs of weight difference WILL NOT make up for a 50hp/50ft lbs of torque power difference. The timesips prove this. I have yet to see a 305 TBI car run below 16.0 at the track. You should learn to mod your car before you come here sermonizing on how close a race between a 305 TPI auto and a 305 TBI 5 speed is.... But that's it, I'm through, I don't have time to waste on fools... I have to pack for spring break.

EDIT: forgot.... ONEFINE8T9, you're an idiot. Go away.

props to Jester for that line.

well tell ya what, when u get a thirdgen even compareable to eiher of mine than talk **** scumbag.

ok well refer all u want that proves nothing. His car could have been modded before he bought it, he dont know and neither do u[to my suprise ] so u can use that as a solid example. No **** auto cars have a TCC, hmm looks like ya tought me something

lol aright well i have taken out ur "so called penut cammed cars" before so i guess those are all a 16 second cars huh

no 100 lbs of weight wont but an extra gear and 5% more power to the ground will.......dumba$$


how about this, u should lear to suck a fat one and not to tell me how to do n e thing to my cars. I dont remember me asking u how to handle my car nor do i remember n e one else asking u.........i know how close the 305 TPI auto race and 305 TBI 5 spd race is. i have been there before. so dont try to tell me

lol ya ok, again i forgot that ur MR knowitall. remember i dont see moderator next to ur name so stop acting like ur **** dont stink.....it does

 

Hey guys, there really is no need to insult each other. It is a DISCUSSION BOARD, if you don't want to discuss, just move on. Your wasting everyone's time by posting these immature, insulting responses.

Well, I have a 305 TBI 5-speed, guess what, it's just as slow as an auto car.

Manual trannys get more power to the ground, but auto trannys have torqe multiplication.

Auto is equal if not faster.

The slowest 305 TPI I've seen ran low 15's, in horrible tune.

My car is in <u>PERFECT</U> tune, My best is 15.6 @ 88 mph, and I can drive.

I'm sorry, but the myth that a 5-speed car is faster than an auto is just that, a myth.

TBI never got a G92 cam.

Dont give me the line about thinking I know everything, I DO know everything.

Pablo, Jester, and myself have all raced together, all with similar mods. My car being the freshest motor at 80K. Jester got a 15.6, I got a 15.7, Pablo got a 15.9.

We all had TBI back then.

Any questions?

 

One more thing, a 100% stock TBI car couldn't break a 15.8, no way in hell, 5-speed or not.

 

ya well theres ur problem, ur freshest motor being 80K

saying an auto car is as fast or if not faster than a 5 spd car is stupid and i wont even give a real response to that

BTW what pablo and jeser got also means nothing, pablo built a motor up to all hell that bearely turns a high 14 second run and jester isnt ever TBI n e more, he ghetto rigged his car up with the old school carb. so i doubt n e examples useing either of them is worth of ****.

 

Ok...

For the 5-speed vs auto debate, you are wrong, end of story, deal with it, I'm not gonna argue with you anymore about that.

Pablo hadn't built his motor at that time, same with Jester. All three of us had the "Ultimate TBI" mods.

That's like saying the Beatles sucked because Paul McCartney had a few bad songs when he was in Wings.

Read what you've typed. You can't judge the past in reference to the future.

As for an 80K motor not being fresh, why do you even drive a GM product, you obviously have such little faith in GM craftsmanship. 80K is just getting started.

Coop had a 30K motor, that I personally did the ultimate mods on, he barely made it into the 15's.

I can sit here all day and prove you wrong.

well reguardless of what u and ur little crew think u arent going to sit here and tell me that 5 spd cars arent as fast as autos. They are faster. proven fact. Prove me wrong? u havent proven n e thing other than the fact that u know nothing. U "played" with very few tbi cars and u think u know it all. I find it funny but hey thats just me. U remind me alot of MRJ, neither of u guys have a clue......

 

o and my point about bringing up pablo and jester is becouse u can abviously see that they also dont have n e idea how to build a motor becouse they would faster than high 14s if they could..........hmm seems as if all u guys have something in common

 

How fast do you run?

 

I've allready raced the guy! I beat him by 1.5 car lengths. You guys can stop bashing each other and move on. By the way his tbi car was an auto. With this stated you no longer need to bash each other. That's what this whole thing turned into over tbi 5spd or auto.

Hehe, good job

 

ok...event though you already raced him and got your answer, I have to point out one thing.

my stock tbi 305 vs freinds stock 305 tpi. Both automatic...I win everytime. Go figure.
