what would be my 1/4 mile time with a 87 350 tpi in a 89 s10 truck with no mods but slicks and about 30hp so about stock hp numbers since hp loss over the years

 

15.2

 

Wow seriously a 15.2 is like a second off any way you spin the dice.
the truck weighs like 3000-3200 and the motor in a iroc z would do better then that, plus i have slicks, a set of 373 gears with posi lock, and a few minor bolt ons, so i think 15.2 is a longshot, im thinking around high 13s and thats what most s10's run with no mods

 

mid 14

 

Hey were you kidding about this time or ? Because a stock 305 tpi can run under a 15 second 1/4 mile, and a 350 tpi about 14.2-14.5 depending on driver, so if ur just going to post about stuff you dont know about then please dont waste my time, thanx

 

weight of your truck?

 

If you weigh a little under under 3000 lbs ,i would guess somewhere in the lower-mid 13's?

 

Ok and ya the truck weighed 2600lbs with factory motor so im guessing like 2800lbs at very most to be generous and i weight 175lbs so 3000lbs basicaly lol, so whats the iroc z stock weight like 3500lbs or so ?

 

Hey so what would be the best hp or tq gaining part for low cost? Im thinking about getting a ported plenum, and getting bigger injectors maybe? But most likely a new cam is out of the question since im looking to spend under $250 for some decent power gain

 

WTH is "no mods and about 30hp"
mid 14's and a ton of wheelhop if it doesnt hook.
A broken 7.5 if it does with your slicks.

 

When my 89 Formula 350 was stock it ran 14.9@92mph and weighted 3353 then. If you already have headers and good exhaust then the most restrictive part of the TPI is the lower intake. Then you might want to get a set of 1:6 rockers to get started. That would prob get you under a 14 second pass.
your stock injectors will cover the HP the engine is making. It will run like pig if you just throw big injectors on a engine that doesn't require them.

 

S10 is hefty. Considering stock gears in those things, 15.2 is not far off at all. You did not mention the 3.73's. That makes a difference. Wheel hop galore. Stall was not mentioned. For what you have me, you would've been within a half second of my estimate. High thirteens? Dream on.

 

What does an S10 have to do with Thirdgen.org? It seems like you already had an answer in your head anyways, so I don't see why you asked the question. If you wanted a real answer you should've asked this in a much more detailed description on the S10 and/or the YB forums...

 

Well i have just a throttle air foil thing, a throttle spacer and a msd blaster coil, but from the hp loss over the years i figured it would be a little under or around stock still so its like no mods

 

well somene wants to be a douche as im asking a question that these members will know better then someone on a s10 forum since its a third gen motor the vehicle its in is only a quarter of what counts so please dont post dumb responces

 

neither of those are really "mods" ,you need stuff like headers,exhaust,intake to add any hp

 

Oh a ported plenum wouldnt really add any hp ?

 

-

 

is the engine in the truck now?

 

ya it is in the truck, and when i posted about the three things stuff i thought u meant something else, and ya idk why i said about bigger injectors lol that like the 350hp range when you need bigger injectors, and how much would headers get me in hp like 30hp at the most

 

Sheesh....................

 

depends on the headers you buy, average on a stock engine probably 10-15 hp.

 

Oh well i have never bought headers so who knows lol i knew it wouldnt be a miracle upgrade but only 15 hp really, wouldnt a new exhuast with stock manifolds get more power like 30hp, or do the headers and exhuast all work together to make more power since there would be alot more flowing out

 

no, exhaust on its own is about 10 hp too.

 

You sure come across as a mouthy know-it-all ill-mannered little b!tch.
Perceptions here are you don't know WTF you're doing, and a 15 sec 1/4 mile is probably pretty accurate.
Now go out and prove us wrong, post a timeslip, with manners, and maybe things will go better for you here.

 

Oh im not acting like a know it all i was just stating that a 15 second 1/4 mile is not rite, and im sure that my s10 will smoke a stock iroc z like it is now, and they can run a 14.2 so a high 13 is not a number im pulling out of my a** and im only 16 so i cant take it to a drag track but dont think because im only 16 that i think i know it all, but ill tell you one thing i know more about my setup then you obviously, and its from hours of watching other s10 trucks with a stock 350 tpi get under 14.5 almost always no matter what and that 14.5 is with launching issues, so please dont think for a minute that im just some dumb a** kid and that im dreaming of hitting the low 13s with nothing more, but high 13s i think it's so

 

well being your 16 you don't know what these cars ran stock. You can watch your s10s on youtube all day but I don't see you getting high 13s with a stock L98 in your s10. The C4 Corvette made the best times of all with the L98 and it did the 1/4 mile in 14.2. The Camaro/Firebirds with L98s ran between 14.5-15.2. You have been coming off as a know it all, when you know just a little. Many of the guys who have been replying have had these cars since they were new so they know more then you. If you wants your s10 in the 13s with a stock engine dump an LS engine in it. If you want your s10 in the 13s with an L98 you'll need headers/catback , step up to 1:6 RR-a little bit of a stall speed converter and Drag radials. I think that would get you real close to high 13's. If you don't like the truth then I can't help you.

 

Oh well then i have obviously been mislead from the s10 v8 swap forums as they all were saying near a 14second and definetly lower then a 15 with a ok run so thats why i came hear, so i could get some info from people with the same motors as me, and just different everything else which just saying a few hundred lbs shaves off some tenths from ur time, and the gears and all so wouldnt at least a 14.3 ish be rite ?

 

LOL!!!!!!!!!!

You should of just told the kid it would turn low 10s in the 1/4 !
I would also mention the low 9s if he had spinnaz, twennyfos, a fart can and a wing !!!!!!!!!!!

 

Geez Louise....those trucks were never designed to be fast. Just because you drop an engine from a car designed to go fast into does not mean you inherit that car's capabilities. There is SO much more to the equation. Can't take it to a track? I'm sixteen. My first car was a supercharged '02 mustang making about 408hp to the wheels. I took it to and ran it at a track just fine. You shouldn't have a problem with a "high thirteen second" S10.

 

Ok i dont have a license yet for one, and im sure their are rules to go to the strip anyways. Also i know my truck is faster then a iroc z as a freind of mine has one thats a 89 350 tpi with auto, and 4.10 gears i think or 373 like mine, anyways i let him drive my truck and it scared the **** out of him and it had the street tires on it so it wouldnt handle like crap and i dont now maybe it has something done internally but i know it would beat that iro z for sure. Also what iroc can burnout from a 30mph roll, NONE STOCK lol

 

Hey come to think of it where could i get my truck dynoed at, like most mechanic shops, or ? and whats the averag charge because id like to know if its running above the stock power or how much it's below

 

your S10 does that because it has no weight over the rear tires. Being your 16 you seem very impressed with something that really isnt very impressive.
If you want to dyno your truck you have to goto a dyno shop, around my way it's like $50 for 3 pulls. I'll save you the money, a stock L98 will make around 200 HP at the wheels

 

Ok well i was just saying that maybe it has something done to the motor because it seems to pull hard but then agin these motors have alot of torque so thats why i want to dyno it so ill know wether its stock internally or not, also alot of you seem to think im a dumb a** kid thats thinking this s10 is the **** or that i know it all and your wrong because i know i dont know everything and thats why i posted a question and i know my s10 isnt the **** either because i have an older brother thats a true car guy and his built mustang and z28 would and do make my truck look like childs play but thats alright because im only 16 and this truck is alot better then driving a gay neon or honda civic

 

*Sigh* so you say it's faster than the IROC because it feels faster, yet you haven't even raced it? If that IROC does have 4.10's it would tear you a new one. My stock 92 z28 l98 feels much faster than my mom's DOHC V6 Supercharged Audi A7, but I promise you, it's not.

 

4.10s are a horrible gear for a 5.7 IROC with a 700R4. 1st gear is already very low and these cars with a stock engine don't like hi rpms. That gear would put it out of its power band.

 

You won't blow your rear. You won't hook up without suspension work. Your truck weighs anywhere from 2,600-2,900lbs depending on body, accessories, etc.
I've been down that road. My SC/SB cammed vortec 350 could lay rubber at 30 MPH with 3.73 gears. I was running a TH350 and a 1,800ish stall and that truck would fill up the road with smoke when I laid into it.
On paper it's going to be significantly faster than what it will actually do.


EDIT:
With a stock TPI setup and having no weight in the rear you wan't a numerically lower gear ratio. The TPI will hit OD with numerically higher gears and be out of its power band. Not to mention all you'll do is waste time at the tree spinning like crazy.


By far the most fun budget toy I ever built. I had a bottle in the back but never got to spray it. Makes me wish I never parted it out

 

Ok i see what ur saying so I should buy like what size gears for the rear, and whats going to be my top speed with these 373 gears and the 3?? sized gears, i forgot what is rite below 373 its like 327's (close enough lol) or something rite, also my s10 has beat his iroc z about three times, and he has the 5.7 tpi with the 4:10's and thats it i think, regardless im faster or a way better driver

 

God delusions of trucks being fast dancing through your wistful head is nauseating.

 

The problem with anything steep like 4.10s (which is technically refered to as a lower gear ratio even though it is numerically higher) on a TPI motor is it wastes the down low torque curve spinning the tires and pushes the vehicle higher in the RPMs where the TPI manifold doesn't make power and possibly causes the vehicle to shift into over drive which is a big no no in racing if you can avoid it.

I am not too familiar with the stock TPI setup but I'd imagine 3.73s are even too much gear; especially for an S10. I can tell you with my higher (numerically lower) 1st gear of the TH350, 1,800 stall and 3.73s caused the truck to melt the tires.
Some quick math; regardless of my converter your TPI makes its torque equally as fast if not faster.
TH350 gear ratios are 2.52/1.52/1
700R4 ratios are 3.06/1.63/1/.7

If we take my S10 as an example and multiply the 3.73 gears, you'd get 9.39, 5.66, 3.73.
A 700R4 with 3.73s would be 11.41, 6.08, 3.73, 2.61.

A more ideal setup is 3.42s or higher (numerically lower; increasing top speed)
10.46, 5.57, 3.42, 2.40. You'd still probably melt the tires off the truck off the line but assuming you have a 27" tall tire you can hit 36 MPH, 69 MPH, 112 MPH, and if your motor allows 161 MPH lol. These numbers are based off 4800 RPM shifts. Someone else may want to chime in on the gearing but I think although you'll lose the "feel" of the power it will ultimately be faster.

 

ya i have like a 29inch slick on now, but it will be coming off and be replaced with a wide street tire alike without all the grip, lol and i know how the gears work from tuning cars on forza 3 lol it does transfer some to real life

 

Lol i have seen plenty of fast trucks, unlike mine, there are s10 trucks with turbo diesel motors and supercharged motors that will tear ur crap up and about everything else on this forum (just stating a fact no offense) so before posting a irrelevent comment please think, thanx

 

you might think about tubbing the rear ...

 

does'nt that cost alot

 

Tubbing the rear isn't all that bad to do if you can do it yourself. You can take the bed off to work on the rails, move perches, then cut the wheel wells off the bed and put it back on. However I don't think it is necessary on a stock TPI motor. A good set of Mickey Thompson drag radials helped hook my truck pretty good.

It doesn't take a turbo/supercharger to make an S10 faster than most 3rd gens. The S10 has one major thing on it's side over the f-bodies and that's a 500lb weight advantage.

Honestly, I can tell you my 385ish crank horse S10 ripped a bolt on/4.56 gears LT1 Z28 (low 13s) apart. And the truck was spinning pretty hard. I'd be willing to bet it would have taken the old bolt on/10 psi vortech supercharged 6 speed Lt1 my bro had too... or at least sat next to it. On the bottle I am certain it would have make that car look silly.


If you want it to hook better get a set of ladder bars or slapper bars and a set of shocks.

 

3.42 is your max with tpi and a 700r4.

 

Hahaha my stuff is almost bone stock, I should hope a turbo diesel could beat me. I mean the thought of you wasting time to make truck fast is nauseating. Why bother, at the end of the day it's a TRUCK. You may go fast but you certainly won't look good doing it. Buy a cool car and make that fast. Oh, and I guarantee there are Camaros on here that those "race turks" wouldn't be able so much as breathe on.

 

hahah lol lol lol please go get a life as I know for a fact that a fast s10 will kill a camaro all day so please go do ur homework the only way a camaro would be winning is with alot of weight reduction and a ton of hp as some s10 trucks are pushing near 1000hp like 800hp usually but still they are fast, and you cant talk about them being slow when ur crap is a stocker, also id rather be smoking ur camaro in a s10 truck anyday as it's always going to be a more impresive win from stoplight to stoplight rather then the average stock camaro

 

If he wants to build an S10 to go fast thats his right. I wouldn't talk bad about building a 1/4 s10 they are out there and I've seen some VERY VERY fast ones.

 

well the guy I got it from gave me a set of traction bars with it, and i plan on buying new shocks with a third one mounted in the middle or wherever your supposed to mount it to help it better.
