You gave us your ET but what is your MPH through the traps?

You most likely dont need to go into the heads or cam route till you are sure you've maximized your current combo. Im going to assume you tow with this truck and thats why you dont have an aftermarket stall yet? If that is the case a bigger cam may not net you large gains in ET if you plan on staying on the stock stall. A real tune will probably fix everything up nicely. Handheld and mail order tunes are crap for FI IMO.

Could you post up your complete timeslip for us to look at? Do you have any dyno sheets as well? IAT info or data logs?

With your current setup I dont see why you shouldnt already be in the 13s if you have a RCSB.

Soon2bespooled, you are very quick to throw out advice without knowing what you are talking about. May I suggest you read more and advise less?

 

F8L, i agree i do throw out simple advice, but i was just answering his questions, i know and have read about FI people using the GT2-3 cam and only suggested that because he asked about heads/cam. it isnt like im advising things that arent realistic and werent ideas thrown out by other users. i was quick to throw out tune and more boost, where was i wrong in that? why dont you target parish, he said the same thing? regardless i know im quick to advise even with joking things like the ET streets but nevertheless i ask just as many questions to make sure i know enough to talk abou t what i do. just take me with a few grains of salt

 

I hear you my friend but I often see you advise something then start changing things around 3 posts later once you read someone elses response. Just seemed more like eagerness to look like you know something that you dont. Or it could be that you simply are eager to help people which is a good thing I meant no offense, just pointing out how it looked to me.

Now, lets see this timeslip so we can help you out gao8302

 

sometimes i say things again if i see the thread started didnt address something that another user mentioned earlier. especially if it was in a long post. dont think this is the case though

 

Take the advice from Parish8. He's a former Whipple guy and I'm a current/former whipple guy. You need to up the boost, get a tune, get a higher stall torque converter.

I dropped my time by quite a bit by going from 33" tires to 31". If you're on 36" with a 9" lift it would look stupid with street tires so.............

I'm told the correct cam could give you as much as 50-75rwhp. That's certainly an option too. Heads with a whipple are debatable, or so i'm told, untill you get to a certain power level where they might become a restriction.

You could also look into long tube headers if you dont already have them.

 

without nitrous i was able to get into the 12's with my 99 ext cab 4wd. seems like 12.60's. that was with the whipple, stock 6.0, yank3000, long tubes, efans and tuning. i did use a little good fuel for that but the meth will help more than the fuel i was using.

 

I went through the same transition with my centrifugal. The stock motor and 6 psi left a lot to be desired. I added the exhaust, stall, 80 mm throttle body, injectors, cam, Stage 2 heads, rockers, springs, oil pump, and water/meth. That fixed my 6000 lb shoebox from acting like a big truck. It is a daily driver with idle RPM of 750 rpm. It is a mild mannered beast waiting on the hammer to fall. Then it gets nasty..... My dyno of 500 rwhp was on a rich tune in 93* Florida sunshine.... I am extremely happy with the buildout and have used most of what these guys are suggesting to you. I run 12 psi boost on stock bottom. I used water/meth as a chemical intercooler. I am running the Vinci cam with their accelerated 1.85" rockers. I have a set of Patriot Stage 2's backed by Pacesetter LT's and Borla exhuast. My buildout has taken 6 months and another 2 months to get the tune right with the 60# injectors....I am still running a stock 60E and stock G80 rear. Those are my next two projects. The 4.56 gears and 35 combo are run on many of the trucks in our truck club. My only comment there is to toss the stock differential which I see you already have. My one suggestion to you is to plan on getting the 4L60E beefed up as you build boost. I would say that is your weak link.......

Hope this helps...

 

I think you guys have me sold on the water/meth. But how long does it last driving around town hitting boost once and awhile. How much boost is ok to run on a stock 5.3? I would like to get as much out of this engine in bolt ons first and then step up to a full engine build. I thought about it all day. Back to meth setup, what is a good brand and does anyone have a part# on it? As far as bolt ons now what else is the best bang for your buck? Thanks alot guys for all the help.

 

One more thing that Flabouy pointed out was the stock 4l60e. This has been in the back of my mind when it is going to go. What parts do you guy suggest installing to make this thing as bullet proof as these thing can get? I know its no 4l80. THANKS AGAIN.

 

one gallon of meth will last for a couple of tanks of gas at least. i have the alkey control kit and it is prety nice. 6psi is about it on a stock 5.3 without meth. with meth i would think 9psi at least. if more than one nozzle you might be able to push it much higher. on my current set up i am able to run 11psi on pump and 16psi with the meth.

i love my meth kit. i wish i had tried it when i had the whipple.

BEST BANG FOR THE BUCK BOLT ON FOR YOU WOULD BE A STALL. but a meth kit would be a very close 2nd. with a stall, meth kit, extra boost and tuning i bet you would drop a full second or more but i dont really know how much those tires will hold you back.
