0-60 times super slow

PerpetualSeanX · #1 Mon, April 23rd, 2012, 12:47 AM

Also, someone suggest I obtain a datalog from my truck, I assume using my gryphon, insinuating that it may help in diagnosing a potential problem. Does anyone know about that? Perhaps someone could enlighten me on how to get it, how to use it, where to post it, etc...Thanks

This one is based on calculations since I don't (and don't know anyone that does) own an 04-08 F150.

All else being equal, you're looking at an additional 18.5-22 HP above and beyond what you have now just to get into the 8.9xx range. Technically speaking, that means that you have to make more torque at the same RPM range in which you would normally be operating during those 9 seconds. I would say that you'd be VERY hard pressed to get that much power out of simple bolt-on parts. 0-60 times are largely based on how quickly the engine gets to maximum horsepower so things like head porting, cams, etc., aren't going to help you at all in that department. Sure, they MIGHT squeak out a COUPLE extra horsepower, but you won't see that until the 1-2 upshift point.......long past the time that it does any good for your 0-60 times.

So, I'm getting that you feel 10 seconds is appropriate. Again, I don't mind 10 seconds, if I had been pulling 11 before the gear change. I'm just confused that there seems to have been no tangible improvement other than that for my engine and transmission wear. That lack of change in time makes me think something is wrong.

So, I'll ask this question directly: Do you feel it is normal to not see an improvement in 0-60 times when someone gears to 4.56 from 3.73 or lower?

I see. Thanks for the write up, longshot. I guess what I'll do since the gears are going to have to be replaced anyways (they're whinning) is go down to 4.10 since I don't tow much and I do a lot of highway driving. That'll bring it to its original powerband.

Maybe it'll give me better results. I'm also going to have the spark plugs replaced since I doubt they've ever been done. I'm seeing a huge gain from doIng the fuel filter and cleaning the maf sensor. Also have the transmission serviced.

Thanks for the help.

Are the data logging for the monochrome the same for the gryphon cs?

Look online for a gear chart. There are tons of them floating around. You compare tire size with gear ratio and inside the matrix is RPM. I think there is also a gear ratio calculator here on either the PHP website or the PHP forum. I just went through the Pegasus program (for my programmer), which has a gear ratio calculator. Using 235/70-17 as your stock tire size and 315/75-17 (approx. 35" diameter), the 4.10 would bring you similar to the 3.55 stock ratio. 4.46 would be ideal to get you to a 3.73 ratio but the next closest gear option would be the 4.56.

The CS/CTS do not have the datalogging. I was thinking you had the MC gryphon for some reason.

Lol, no big deal on the MC thing, I kinda figured there wasn't datalog, I've gone through all the menus pretty thoroughly.

Well, I guess I'm in the right area for gearing if thats the case with my 4.56's considering I had the 3.73's to begin with stock.

I just called a couple places to do my spark plugs (I really don't have the time to deal with broken spark plugs) and these dealerships around me are out of their damn minds. . .One quoted me 360 something plus 115 if they broke one or more plugs, the other was $600!!!(Didn't even ask about broken plugs)

I may end up having to find time if I want them done, not sure I can stomach paying that much for a spark plug change. . .

I just pored a can of Seafoam into my gas tank to clean up my jets a bit, add that to the list of things I've done to get this truck running as well as it can.

Aren't you also a member on F150online? Just ask if you can borrow somebody's tool set. I'd also ask local auto parts stores to see if they'll rent them. I've seen some write-ups where they spent a bunch of time and got them out carefully. Spark plugs are relatively easy...can't say they are easy because I built a bike that just about beats all on ease.

Run techron or chemtool, they contain solvents like toluene and xylene that chemically break down carbon deposits more effectively. Seafoam does not, the only solvent it has is naptha (25-35%). The rest is pale oil for lubrication (40-60%) and 10-20% isopropyl alcohol to draw out water.
