What will it take to get into the mid 12's on 91 octane and on F1' with no more than

I have not taken my truck to the track yet, but judging from some of the posts here my truck should be running around 12.8 - 13.1 on the 1/4 mile (good weather driver,track). Since I live in CA I have a single chip program with JDM's J39. I have the stage one, 4# lower pulley, magnaflow 12568 and NGK tr6's. If I add a cat - back, E-fan, and throttle body, will it be possible to get into the mid 12's on stock F1's without increasing the boost?

Thanks

MAYBE, MAYBE NOT !

The cat-back won't help much with ET, the stock exhaust is really very free flowing. Most people change the exhaust for the sound. The throttle body is good for a few more horsepower, depending on other mods. The electric fan is a good idea. My opinion is you will not get to 12.5 without increasing boost (or adding NX), but I could be wrong. You should take the truck to the track now and log what ET and MPH you are getting. Or run it on a chassis dyno. This will serve as a reference point for futher mods. The best way to document what is working is to dyno or track test the truck each time you change something. When you do a bunch of mods together it is sometimes hard to tell what helps and what does not. Although you can compare your truck to others on the board, sometimes these trucks respond differently to different combinations of modifications. You never KNOW for sure what works best until it is tested on your truck. It is possible to increase performance slightly with one mod and then take away that slight increase with some other mod. It is the final combination that needs to work together. Opinions vary, and, of course, there are proven combinations that work well. Find a tuner you like and stick to one person's advice, and your truck will be in the mid 12s just as soon as you spend the appropriate amount of $$$$$$$$$.

You need to find someone in your area and at your track/tracks that runs an et close to what you would like to run and talk to them.
There is a huge difference running on the east coast at sea level, and with there great barometric pressure and well prepped tracks compared to the midwest with terrible air and higher elevations,for example.
Above is one example of differences in et around the country for L's with the same mods and weight.
As far as california...your gas can't help and iv'e heard a lot of the tracks don't hook for one reason or the other so like i said talk to the locals who are getting the et's you want first, then make a plan.

Brasil, where in CA are you located? F-1's aren't going to do you any god at the SoCal tracks. There is no traction.

Irwindale has the best traction, but is only 1/8 mile. Get yourself some Hoosiers or ET Streets. If you have 3.73 gears, the 28" hoosiers seem to work best. With the 3.55's the 26" tall Et Streets seem to have an advantage.

You may consider a race program for the chip. One that will run on 100 octane. The street chips that run on 91 octane will sacrifice .1-.2 in the quarter mile.

You will probably need traction bars too!

Listen to Jay, from what I have read on this board, getting a truck into the middle twelves (on F1's AND 91 octane) in southern Cal aint' gonna be easy. I think the traction is better out on the street.
It can be done, but since you have limited yourself in the traction department and the fuel department, then that only leaves the engine. You are going to have to move a lot more air and fuel thru the motor and use very conservative timing (for the octane).
This means a complete exhaust system, a 6+ lb pulley, a PSP or JL cold air intake. See what I mean, you are going to have to build a lot of power on a conservative tune and then try to drive it thru crappy traction.

This isn't as easy as it sounds and could get expensive. The more power you build the more the tires become a liability.

Now if you had a descent track and some descent tires, a chip and a pulley should do it.

Jay. I live in Fresno. I think the closest track is in Bakersfield, but I am not sure. I really appreciate your replies. My lightning is a 01, so I have 3.73's.

I am still not decided on wheather to get the bassani or silver bullet cat - back. Any other opinions out there? Is it true that you can actually loose power with the bassani? From the sound clips the silver bullet seems to have a deeper more muscular tone, and the bassani a louder, raspier, but not as deep. Any comments?

I am concerned with some of the reliability issues such as rust that have been brought up by some of you here regarding the MAC exhaust. Will the silver bullet give me any power increase versus the MAC? Is the price difference really worse it? Does a system set up with two mufflers make a big difference from the ones with a single? Thanks for the replies

well you live in CA you will have no rust problems for atleast 5+ years.

the price is over a 200$ difference mac being the cheapest. i doubt you will keep the truck more then 5 years and if you do buy another mac for the same price and its still cheaper then the silver bullet

power will be the same.

two mufflers is louder then one

Brasil, most guys down here that are in the 12's are running 4# pulleys. They can be safely used with 91 octane, but I would be careful with the chip tune-up.

I'd definitely go with an chip filter and pulley to start with. Save your money on exhaust for now. I have been running an stock exahust and 2# pulley, and have managed to run 13.11 @ 105. I know there is a 12 for me if I can get the truck to hook up.

Quite a few guys have run at Famosa (Bakersfied), but I think you would be better making the trek to Sears Point or Sacramento. Both of those tracks are near sea level, and I have been told, they have decent traction.

I ran at Bakersfield, and won't go back until the weather is cold. It's a greasy track when hot.

Jay, I already have JDM's single progrm (J39), with 4# lower pulley, cold air kit, line mod valve, 4 x 4 trans. pan, tr6 plugs, and single 12568 magnaflow muffler (barely louder than stock). My chip was reburnt when I purchased the pulley. I don't want to increase the boost anymore (just to play it safe, unless the internals are beefed up). I can't understand wwhy ford didn't use the manley rods like in the cobra. I think my next mods in order will be:
1) The bassani or silver bullet (mostly because I want a deep muscular sound and rumble
2) E- fan with water pump
3) TB

later
