stock motor TPI Vette: 13.16 at 103.58mph

[warren s]

BTW i've seen LT1 vettes run 13.8's and faster. i've seen LS1's run 14.2's and faster. so your going to tell me a LT1 can not be faster than a LS1?

I dont know haow you got that I was syaing that....But I did state that an LS1 can run a 13.1, and thats a respectable time for a car with a wider torque band and 100 more stock horsepower than a 1989 Corvette came with.

setup and tune doesn't have nothing to do with how much HP the car is making but makes all the difference in the world on how quick the car runs.

Maybe the "setup" wont change the HP at the rear wheels, but the "tune" can make a major differance.

driver skill + car setup = quickest times.

It dont take much driver skill to make a good pass in many fast cars these days. In my 95 (13.4s) all I do is floor it when the light turns green. Nothing more. As for setup, thats back to the origional point.

 

[tpivette89]

With only "free mods" and simple bolt on items a 13.1 is still very fast and would represent close to a 100 Hp gain over stock.

Corvetteforum member Vic89 has the same year Vette as mine. he has replaced the TPI intake with an Accel base, and AS&M runners. with only those changes over my car he has run a best of 12.81 at 107mph with a 1.73 60ft. he has also dynoed his car and came up with 270rwhp. thats not even 100hp over stock (and hes trapping 4mph more than me). i dont know where youre getting this 100 hp figure and why your so adamant about it. its obviously not right, or youre not looking at the total picture. theres gearing/torque/and driver ability youre forgetting about

Tpivette89-

Lighten up dude, no one is calling you liar!

All I am saying is it takes way more ponies than a "Stock" 89 Vette makes to go 13.1


270 Rear wheel HP is way over what a stock 89 would make.
250 SAE NET is about 210 to 220 at the rear wheels.

your right and no one is stating it is "Bone" stock. but the motor, tpi, and rear gears are! even the 48 mm TB is.

You said its a 3.07 rear gear ratio

The torque curve of a stock motor 89 is low and short

No matter how great a driver you are, it would take about 100 hp over published stock (250) to move a car the weight of a 1989 Corvette down the track in 13.1 seconds.

I dont mean to attack any ones credibility.

try only 50 or 60 at the most with a set of Drag Radials and a stall converter. that is good for 3-4 tenths right there.

the 3.07 gear ratio is the RPO code of G92 if memory serves me correctly and that is a stock corvette gear set.

this matter is starting to become a mute point cause obviously you can't or won't believe a modded TPI car can run faster than a stock LT1 or LS1 car.

BTW i've NEVER seen a stock LS1 C5 run 13.1 at the track NEVER you know why? cause most people that own a vette can't drive a vette! let alone race a vette! i've seen stock Trans Am's run 12.8's stock! now a stock F-Bod shouldn't run faster than a stock C5 by any means so whats this tell you? F-Bods are driven by younger people that actually drive them the way they are built and the C5's are owned by older guys that only cruise them to work and back and when they do take them to the track get so ****ed cause they get beat by old C4's, mustangs and everything else cause they can't drive them.

Lighten up dude, no one is calling you liar!

you are doing both things with this statement:

my car, as well as other peoples cars prove this wrong. Vic89s Vette has 270rwhp... thats about 335 crank hp. thats 15hp lower than your 100 added hp necessity. my car is slower than his, and youre saying i need 350 ponies to run a 13.1?

 

[warren s]

YES, I am saying you need between 325 and 350 horsepower to run a 13.1 in a 3300 pound car, plus driver weight, and a 3.07 rear.


As for you thinking thats like calling you liar, well sorry you take it that way.

sorry man but you are wrong and obviously don't know nothing about dragracing.

if you can get the 60's down like tpivette89 has done (1.7's) you can have 300 hp and run the numbers he is.

your arguement about LS1, LT1 cars compared to a mildly modded TPI car that can 60' is very mute and going no where. you are comparing apples to oranges here. take a LT1 car or a LS1 car and do the same mods and the LT1 car will be around 12.8's and the LS1 car would be around 12.4's.

now you can compare the 3 cars.

just curious then, how does a LS1 car run 13.1 when a LS6 car runs 12.0's to 12.1's with only 50 more hp?

 

[tpivette89]

YES, I am saying you need between 325 and 350 horsepower to run a 13.1 in a 3300 pound car, plus driver weight, and a 3.07 rear.

and i just proved you wrong with Vics car. 335hp and 12.8s

C5s and LT1 Vettes do not 60ft like i do. theyre more than likely in the 2.0 - 2.1 sec range. if i ran a sucky 2.1 in the 60, then i would be running mid - high 13s. if a stock C5 60fted 1.7s it would be in the low 12s. the launch is VERY important, and you just cant grasp just how much it is

 

[garycr14]

To post a 13.16 1/4 mile time, you'll need approx 285 RWHP, in a 3300 HP car, of course this can fluxuate depending upon tires, transmission, rear gears, track conditions etc... One thing you must keep in mind, not all cars are created equal. You can take 5 brand new 100% stock vettes to the dyno, and get 5 very different HP ratings. The only way to settle this debate is to have the car dyno'd, then you'll know what the car is capable of.

Have fun!

 

[garycr14]

Sorry I meant to say 3300 pound car!

 

[tpivette89]

thank you! why cant this warren guy grasp that?

The only way to settle this debate is to have the car dyno'd, then you'll know what the car is capable of.

after i run at the track this week, im going to get the car dynoed. im willing to bet i dont come close to 350hp (285rw). im betting ive got somewhere in the 250-260 range (rwhp).

To post a 13.16 1/4 mile time, you'll need approx 285 RWHP

and ill post this one more time:

Vic89s 89 Vette... 270rwhp, 12.81 at 107mph w 1.73 60ft

thats 15 less RWHP than the "required" amount AND running faster than 13.1s

gary thanks for the feedback! i think thats what we both been trying to say. it is modded but only slightly. DR's help alot! stall converter with 3.07 gears helps alot and so does just tuning the car. also the track he runs at is prepped alot better than the one i run at! his is good for 2 tenths quicker than where i run cause they don't prep the track at all

racing your car once every few months you could never get a good accurate baseline of what it can do. tpivette89 has put down over 60 passes this season in his car tuning it and know how to launch it consistently. if you don't get the seat time you'll never run the big numbers!

“sorry man but you are wrong and obviously don't know nothing about dragracing.”

“if you can get the 60's down like tpivette89 has done (1.7's) you can have 300 hp and run the numbers he is.”

I don’t know nothing about dragracing? Since you are getting personal, let me state that reading comprehension and writing is obviously not your strong point. All I have been saying is that it would take much more power than a stock 89 to turn a 13.1, Obviously that same power would be needed to run a 1.7 second 60 foot time.

“your arguement about LS1, LT1 cars compared to a mildly modded TPI car that can 60' is very mute and going no where. you are comparing apples to oranges here. take a LT1 car or a LS1 car and do the same mods and the LT1 car will be around 12.8's and the LS1 car would be around 12.4's.”

I never “compared” any cars, I stated the published horespower of each and the respective ETs.


“just curious then, how does a LS1 car run 13.1 when a LS6 car runs 12.0's to 12.1's with only 50 more hp?”

Stock LS6s don’t run 12 flats, they are closer to the 12.4 Or 12.5 range, or about half a second faster than a LS1.


C5s and LT1 Vettes do not 60ft like i do. theyre more than likely in the 2.0 - 2.1 sec range. if i ran a sucky 2.1 in the 60, then i would be running mid - high 13s. if a stock C5 60fted 1.7s it would be in the low 12s. the launch is VERY important, and you just cant grasp just how much it is


Right I just cant grasp that. Maybe spending a day at Atco running high 11s and low 12s in a 69 GTO last Monday blurred my brain. Actually what I cant grasp is how a 89 Tpi motor car with only the work you described can run a 60 foot short time of 1.7. That car I just mentioned was producing 500 HP and ran a best of 11.93 with a 1.60 short time.

But I will conceed that you guys are right, I know nothing.

peak hp is not the end all be all of whos gonna win in a drag race. i dont know why people only look at the hp #s and make assumptions about performance. sooooo many other things come into play during acceleration than sheer hp #s. ever heard the joke about Supras? "what do a 400hp, 600hp, and 800hp Supras all have in common? they all run 12s" all 3 of those cars have insane amounts of hp, but the turbo Supra is very hard to hook up. these things spin almost all the way down the track, which adds up to sucky 1/4 mile times.

ok, thats an easy one. take one car producing 375+ ftlbs of low end torque. add a set of drag radials heated up properly for a sticky launch. throw in a stall converter that allows me to launch at 2000rpms instead of off idle. see where this is going? there are many TPI Vettes on www.corvetteforum.com producing these kinds of short times, im simply amazed that you havent heard of this before.

Stock LS6s don’t run 12 flats, they are closer to the 12.4 Or 12.5 range, or about half a second faster than a LS1.

they can actually. with a seasoned driver they can easily hit bottom 12s. the same driver in a regular C5 can hit mid 12s. i have personally witnessed a 02 Z06 turning 11.6s at 120mph with only a blackwing filter and a set of drag radials. he was pulling 1.6x short times

The comparison about the Supras all running 12s is just plain silly.
I can say the same about the L98, it puts out large amounts of torque in the bottom end, good for off the line starts. BUT is does not continue to put out that same torque all the way down the quarter mile, it runs out of breath way sooner than a stock LT1 or LS1.

Corvette forum? Just went on a crab trip with Mr. Mojo and comapny. As for a car producing 375+ ftlbs ot torque, yeah it no issue to run a good time, but a stock or slightly modded L98 doesnt produce that much, and certainly doesnt do it for more than its bottom end.

I raced many Z06s in the corvette challenge series (with the corvetteforum guys) and never saw a bone stock one hit the 11s. My last run of 13.5 was against a Z06 running 12.44, he had the air intake replaced. Headers and X pipe, blackwing and a Corsa exhaust would make a Z run 11s

then you should know all about these guys in their low 13/high 12 sec stock motored TPI Vettes: Vic89, 65Z01, TA, TIMSPEED, and myself. and knowing Mr. Mojo, how can you say that LT1 Vettes are only good for mid-high 13 sec times when his own 95' coupe went 12.9 with only a cut lid and the mufflers removed??

As for a car producing 375+ ftlbs ot torque, yeah it no issue to run a good time, but a stock or slightly modded L98 doesnt produce that much, and certainly doesnt do it for more than its bottom end.

stock TPI Vettes have roughtly 100 more ftlbs than hp. so starting off with 350, then remove the restrictive exhaust, add in a few free mods, and some tuning with timing and fuel pressure, and youve got close to if not exceeding 375 ftlbs. thats more than enough to produce 1.7 short times with traction and a 2000rpm launch

Headers and X pipe, blackwing and a Corsa exhaust would make a Z run 11s

you forgot the "crappy driver" mod. like i said, ive PERSONALLY WITNESSED a Z06 that was bone stock, with the exception of a filter and drag radials, go 11.6.

but anyway, my runs have been proven. i have the timeslips, people have seen me run the 13.1s, and i have one of the passes on video. i have done all the work to the car myself, and know for a fact it was original when i bought it. when i get back from the track this Wed (which by the way im shooting for 12s with the colder air temps, a ported intake, and a crank pulley... how much hp will you say i need to hit 12.9?), im gonna get the car dynoed. i bet the car will not produce more than 260rwhp. people who tell me my car cannot run what it does with the mods i have only make my accomplishments that much sweeter, especially when i have proof that it can

Franks car ran a best of 12.99, there is trememdous differance between a 95 that stock runs a 13.6, hitting 12.9, and a car that runs 14.8 stock running 13.1. And I never said LT1 Vettes can only run mid to high 13 second times, I said that was their stock published times. (mid 13s)

Good luck with 12.9s on Wens

 

[*89x2*]

i'm sorry a stock 89 does not run a 14.8! ask 89x2 what a stock 89 runs with only a chip! 13.8

sorry you guys are not adding up. bench racers don't count

Since I have been mentioned

My 89 ran a best of 13.5@105 on the stock Gatorbacks at Capitol Raceway - I have had the car since brand new.
249hp@ rr wheels.
Mods: Chip & Exhaust. (car has been maintained and had a recent tune up - FWIW)

Every car is different - some run well, some are avg. and some are pigs...

enjoy
