Considering my current mods, what's the best and most cost effective way to drop, say, 3-4 tenths of a second off the quarter mile time. Now, to go a bit further, i'm wondering the best way to do this without slicks/tires, stall converter etc. In other words, i'm looking for HP/TQ upgrades not suspension or grip.

I've considered the fan/waterpump/throttle body, but they seem to only give small gains. Any other ideas?

 

Long tube headers and high-flow cats are a good bet. They are not cheap though. Nitrous will do the trick; but, a good set-up is not exactly cheap either.

 

Without slicks you're going to have a hard time finding mods that will gain that much. The main enemy is traction and until you defeat this enemy you'll literally spinning your wheels.

You could buy the mods that you mentioned and gain a little but until you get the L to hook up and lower your 60 foot times you're wasting money. Your mods and mine are very similar and I gained 2.1 tenths in the 1/8 mile simply going to slicks.

The best bang for the buck, with your mods, is slicks and wheels.

I hear you, i know i can gain HUGE in the 1/4 with slicks. I plan on using them in the near future. I'm trying to find more power to give me the upper end. My trap speeds are at best in the 105's. I wouldn't mind seeing 107's even if the time was the same. The reason i'm showing those numbers is because i want the power on the street MORE than i want the power at the track. I may hit the track once a month or so, but that's about it. Then again, it's now 6 months in jail here if you get caught street racing...

From what i've read on headers/cats, they don't give much gain in power or HP/TQ or at the track. This is just what i've heard and i haven't seen any different. If anyone could show an honest 15-30 HP/TQ on a dyno, or a drop of .3(ish) in the 1/4, i'll sign up!!

 

True dat!

Depends on who you trust on the subject I guess. There have been conflicting reports. In time, I'll know first hand. It seems that just removing the pre-cats would make a noticeable difference. The LTs with the high flow cats should make a very nice gain. There are those that have reported such.

 

WOW, I wish I could gain 2.1 seconds in the 8th, I would be in the 5's.
I would go with a 6# pulley and get a program for racing fuel, 104 octane. That together should get you 3-4 tenths in the 1/4.

 

An electric fan, water pump, and throttle body will increase your top speeds for sure but are you willing to spend in the neighborhood of $1200 or more for a few MPH in the 1/4?

It seems like a lot to pay for such a small gain but It's your money, go for it.

oops! Glad you caught that, hooters of usa. I edited it, sorry.

1)increase boost to 6lb pulley and a 2lb upper......and put aside some money for a new motor...
2)Electric Fan , tb, and pump may be good for .2 with your mods,
3)You could have the chip burned more aggresively
4)Headers along with headwork could increase your flow

Or you could face the fact that traction is gonna be your number one issue at this point and your money would be best spent on that.

Traction bars and and drop shackles should prevent the truck from squatting as much and may increase your numbers. Try an intake kit for starters. People can say what they want about the k&n panel and airbox mods.......and dyno numbers.....you arent' pulling the air on the dyno like you would if you were moving and i've had both and the intake will make a BIG difference, especially if your running a 4lb pulley.

hehehe just playing with ya buddy. I new what you meant.

 

Sounds like i'm not going to get what i want in a "street" machine. I just don't want to spend the money on the TB/fan/pump. I don't want to go NOS either. I just want an extra 20-30HP for a $1000. Can't i have that? Come on, please???

 

i remeber seeing a post about the oil breather cap actually makes you loose power?
who ever posted the info did a dyno with and without the oil breather cap, and made better power without it?
use the search function there is a thread about it somewhere... may find the extra 10th's you need by removing the oilbreather cap, it doesn't stop the oil in the intake anyways from what i have read.

 

your chip has to be programmed for the breather cap......it's been said a bunch of times.

Weedo buddy, you said you want an extra 20 hp for 1000.....

throttle body, e fan, and pump is about 1100.....there you go. None of us have any secret weapons to sell ya so if that's what your waiting for go spend some time driving your truck around some more and maybe your appreciate what you already have. If you wanna play, you gotta pay buddy. Here's a new lightning community motto for us....

*****Mods just don't grow on trees!!*****

 

There is no way in hell he will gain 20hp from a Tb/fan/water pump.
