So I Went To The Drag Strip Last Night....

[Andy]

Anyways I Went To The Strip To Have A Little Fun My S-10...v6 4.3 Stick..intake Flowmaster And A Hypertech "placebo" Chip..haha...i Can't Seem To Get The Time To Go Back Home To Get My Posi And 3.73 Gears..oh And I Also Filled Up My Air Shocks....it Helps When Taking Off.....my Slowest Time Was A 16.5...my Fastest Was A 16.2 @ 85 Mph....i Can't Seem To Get That 15.8 I Got Back On The Kansas Speedway....oh And I Raced To Hatchbacks And A Freakin Corvette.....i Beat Both Imports And Was Chewed Up And Spat Out By The Vette....but Hey At Least I Got Beat By A Chevy.....hey Anyone Know How To Increase My Top End Speed...it Felt Like My Truck Was Lacking A Bit In That Area....my Take Offs Are Great....but It Slows Down Towards The End...

...hey Anyone Know How To Increase My Top End Speed...it Felt Like My Truck Was Lacking A Bit In That Area....my Take Offs Are Great....but It Slows Down Towards The End...

Heads/cam, N20, blower/turbo or a V8. Top end is where the 4.3L lacks.

Top end is where the 4.3L lacks.

Amen to that! I think your best bang for the buck, Andy, would be a relatively inexpensive ZEX wet nitrous kit. Spray in 2nd gear after you've gained traction and stick with a 75shot. I tried using 100hp nozzles and my truck got pretty warm in the summer. In the winter time here I don't think I would have any trouble but I also don't use the bottle any time during the winter so...

There's no picture but it's the right kit for our 4.3's. You can spray 75-125hp just by opening the bottle, arming the system and pushing the gas pedal to WOT.

Whatever you do stay away from a dry kit. You'll basically be asking to replace your motor. And another thing, if you do go with nitrous get the recommended ZEX spark plugs which are colder burning to prevent detonation. Otherwise just retard the timing - or both.

I should have went too, maybe I would have seen you there. I can't seem to get any better time than 16.8, but at least it's consistant. I just have a k&n intake, flowmaster muffler, hypertech programmer, and zexel torsen posi w/3.42 gears. My truck is an automatic and I'm still trying to figure out the best way to launch it.

Cool i'll look into it...would i need to upgrade anything else?? or can i just run that with out the fear of blowing my engine....hey how much faster would i run with the bottle..??

It's hard to say but I guess somewhere around low 14's around 95mph or better. That would be worst case scenario at a 100shot.

[bonecrushins10]

mmmm wat kinda tires are you useing and air pressure your running ?

seems like a n2o is tha only thing you can do with out gutting tha engine , for a better cam an heads or just str8 up ls1/2/6 hahaha anyways or could do some forced induction but powerdyne's dont push 8 psi like a vortech would , or if your a real technical guy you can mock up your own remote turbo setup .

[Rob]

...or if your a real technical guy you can mock up your own remote turbo setup .

Or your own supercharger set up :D.

[Danny_SS]

Give us more details on your truck, mods and run. Tell us the Year of your truck , reg cab, extended cab, exactly what engine you have, what tires were you running, your tire pressure, your rear end, 60' times, slip, launch.......etc.

as for ways to really help your times, NOS is the cheapest way to shave 1-2 sec off your 1/4 mile time.
To have those gains all the time a supercharger setup would be better but cost more. A custom turbo setup is best, but its kinda hard to pull off unless you have the SYTY manifolds which are hard to find and expensive. This would also take plenty of tuning but it would be REALLY nice.

Ok my truck is a 2002 single cab, v6 4.3, k&N intake, flowmaster, Hypertech chip,and just some goodyear tires, with the recomended PSI. my rear end is a 3.08 open diff.....heres my fastest time slip.


R/T....133
.60....2.369
330....6.960
1/8....10.431

hypertech chip ? you sure your not useing a tuner ? cuss only tha 95 an down use chips bud

i'VE ALWAYS CALLED IT A CHIP...GUESS I WAS WRONG...I BOUGHT IT OFF THE NET IT'S THIS BIG GAME BOY THING WITH A CABLE...MY BAD

[Rinkrat456]

For about the same price of a nitrous kit you can find a posi unit with 3.73's. You can lower your tire pressure down to 15psi or so and bring the RPM's up before launch. With an open differential I'm surprised you aren't spinning your tires for the first 60ft. Going with posi and 3.73's will still make it so your truck is a daily driver but with a lot more grip. You'll launch harder and be up in the 4400-5300RPM power range at the end of the 1/4 mile with 3.73's.

Do one or the other. Nitrous or rear end. Doing both (if you ever thought of doing both that is) would create traction issues up the woohoo with 100 more hp and 3.73's. You'd need drag slicks at that point, or at least a 285 section width tire aired down and new rims in the back at least 10" wide. If it were me I'd just go with nitrous. Later on in the future upgrade to a Zexel posi unit and 3.42 or 3.73's.

If it were me, I would run the nitrous with a 3.42 Zexel rear end. Hit the N2O in 2nd gear like Rink said and you should be ok with traction. If not, just get a set of drag radials and hit it off the launch.

Hmm, or just do 4.10's, and hit the nitrous off the line launching 2nd gear.......lmao

I would start with a 3.73 rear end and a Zexel Posi unit. The rear end could be found off a 4cyl 5 speed S-10 for about $60 at any wreck car lot. (that is how I got mine) The Zexel posi unit can be found on the 98+ f-body used but in perfect shape for about $150 at a lot or ebay. You need traction before you could add power. Once you have traction you can go ahead and get a Nitrous kit and add an extra 75-100hp. Make sure you get rid of that Hypertech tuner before you get nitrous.

[Rinkrat456]

Make sure you get rid of that Hypertech tuner before you get nitrous.

Why? :confused: I love using my Hypertech programmer in conjunction with the Venom kit.

[Danny_SS]

The programmer advances the timing and many times even leans the mixture.
Advanced timing +nitrous= detonation= KABOOM

you could keep the programmer to play with shift points, rear end gear ratio and stuff like that but the performance program MUST be un installed and returned to stock settings.

Programmer+retarded timing+nitrous = no kaboom.

It's not an evil handheld like you think it is. If I had one complaint about it, it would be that in order to change settings on the fly I have to be at a stop light for a minute and shut my truck off to upload a different program. I have one set up for tall tires and torque/haul mode, another for summer rims/tires and nitrous and another mode for economy.

[Danny_SS]

Programmer adds timing, retard subtracts timing means that the programmer is not doing anything for you when it comes to the engine management since you usually need to retard even the stock settings to run a big shot of nitrous.

I dont think it's evil, I just know that the program is not useful with the nitrous.

[Rinkrat456]

From the stock tune, I retard the timing by 4 degrees when running a 75 shot of nitrous. When I ran a 100 shot for a week or two I didn't change the timing, I just swapped in colder burning spark plugs.

You may think it's a waste of money but in your words, it tickles my pickle. It does what I need it to it has been a great $300 dollar purchase.

So it tickles your pickle huh?...lol
Naw man, no need to get defensive, I'm not bashing the programmer or anything just in case man. ;)

I have no experience with the programmer. I installed a chip a couple of years back and returned it because it did not make my truck any quicker and it cost money. Obviously the chip does not have anywhere near all the features that the programmer has. Actually features like the speedometer calibration thing to compensate for the 3.73 gears , tourque management, raise the rev limiter a little bit, and raise the shift points 200-300rpm would be very useful for my truck, especially now with my more recent mods.

Now how does the programmer make power and maintain its emissions legal thing? TO the best of my knowledge it makes the power by advancing the timing. More timing and nitrous does not go together to the best on my knowledgeand means kaboom. You know that and that is why you use a retard. See you are aware of that and use a retard so that is fine since you know better. I cannot assume that the guy asking the ??'s is aware of that so i have to say that + timing (chip) + nitrous= bad. Bottom line is that I would REALLY hate to hear of some guy go and run a chip and nitrous, not do anything about the timing and damage his ride.
By the way the fact that you can so easily modify the programmer is really neat. And yes the ability to change programs on the fly would be even better.

[Rinkrat456]

Mine isn't exactly like the Hypertech tuner for sale to the public. Yes it's a hand held tuner and yes it's made by Hypertech but it's for "commercial use". My dad used to be in charge of the automotive department in the county sheriff building. All the police interceptors, squad cars and undercover vehicles use the same software to change their own settings. The mechanics create applications/tunes using laptops and upload the data to the Hypertech hand held. When Minnesota got a large shippment of Camaro interceptors they sent along a few Chevy Blazers. Blazers are used around 3M for "security" purposes. Basically the Blazers get yellow lights and a few SECURITY decals but with the purchase of the Blazers came unneeded Hypertech tuners.

So anyways, my dad brought home a hand held Hypertech tuner for me provided that I purchased it to make it a legal transition with paperwork. The nice thing about the commercial one is that I'm not limited to one vehicle. The public tuner is used on one 4.3L and you can't move to another without completely resetting the 1st 4.3L back to stock. Mine on the other hand I have used on my truck, my sister's and a few guys from school who also had S10's.

As far as emissions... everything complies with California smog laws, unfortunately. Meaning I can only advance the timing so far until the O2 sensors tell it to stop. Having the Hypertech tuner used to allow me to edit tire size and ring and pinion ratio since I used to change from 3.42's to 4.10's regularily depending on the season. Now I just have 3.73's so I've taken the middle ratio with this Ford 8.8". Since I still change tires and rims often that part of the programmer is still valuable.

Since the summer I have removed the nitrous setup except for the wiring that snakes through my truck's interior. However, during the summer it was really nice to be able drive around with economy as the main setting and stop at a gas station and change to the nitrous setup while filling up with premium at the same time. The tuner allows me to take full advantage of 92 octane, retards the timing and removes the governor. (It doesn't "remove" the governor - by law it can't - it just places the governor at 170+mph where I obviously can't go anyway) That is setting #2.

Setting #1 is economy. Basically it made shift points 400rpm's lower so the engine doesn't consume as much fuel and it advances the timing by very little just for the extra advantage. In economy mode it also takes advantage of 92 octane gas. The few extra pennies I spend at the pump for premium equates to an extra 2-3mpg so I come out even or ahead if I feather the gas.

Setting #3, which is basically the opposite of #1 and 2, advances the timing and prolongs the transmission shift points allowing me to stay in the higher RPM band if I'm towing anything or hauling stuff. This is basically what I stay in most of the fall and winter during hunting and fishing season because I'm either towing a duck boat or hauling an ice house and gear/decoys. Setting #3 is set for 31" tires in the back where the other two settings are set for 28.5" tires keeping my speedometer in check.

So I hope I've explained at least why I find the Hypertech tuner useful. I figured a long explination of this would better suit whoever's reading it, and yourself included, rather than my quick comments. I appologize by the way for getting a little defensive. You and I are on the same page about how to use nitrous and a chip/tuner properly we were just speaking different languages. (I think)

[Danny_SS]

That is sweet.

They would not have anything like that for the 94 cpi do they?

[Rinkrat456]

96+ It needs OBDII I think - don't quote me. Ask Rob about TunerCat though.
