that is some nice numbers for the lil 4.8 you gotta let me know what cam you are running. very nice

 

I agree, lets see a graph. If not, could you tell us where you saw gains?

Thanks

 

I wish I could post the graphs I have before and after graphs also. but they are on paper, and I donot have a scanner to copy them.
I am sure some of you guys are skeptical, but I assure you at the end of the run it hit 325 on the torque.
the graph doesnt begin untill 4,000Rpms.
and the 325 ft. lbs. was acheived from an all gear pull.
when I did the run in third it only hit 278.2 lbs.
I acheived more by manually shifting it than I do letting the computer do it. this is because the PCM has not been corrected for the new setup. hard to explain. but my shift points are way off, and it doesnt shift right. so this is why I manually shift it.
I can assure you anybody around me can check it out. The guy that dynod it is well know around her.
02Denali and, BBLS1 know of him. (he owned the 10 sec Mustang that was featured in Fast fords)
I will tell you this the graph showed some strange things going on at the end of the run..... valve float or something. going on. I think it has to do with the tuning. and will find out here shortly.
I am in the process of purchasing some new lifters, and springs. and will see if the helps, any, with the tune

 

it really starts to pull above 6000rpms.
and the graph shows this

 

ok this is the only way I can post them
MTI run before cam swap
both runs in 2nd gear


Flat Rate run, after cam swap
first run in red, all gear run
second run in blue, 3rd gear pull

 

I suspect when you get that cam dialed in, your horsepower numbers are going to go way up. Great job on the truck, congrats on such good torque numbers. Now within the next couple months, I am going to install the old man truck cam, just ordered it this past Thurs., so I may need to talk to you on some pointers that may make the install a little easier.

 

thanks

 

Glad your happy with those numbers. I understand It being hot and all but those are helluva low for a full bolt on AND cam 4.8. Considering I did 250hp with UPD and hpp3 as only mods. Yes a tune will help ur numbers but not to the extent that you will get more then 275 or so.

And u achieved those torque numbers by spikin the dyno aka the convertor flashin between shifts which are not a true representation of the power at the wheels. Hopefully track numbers will look better then dyno numbers.

 

cool hope you get it all worked out danial.

 

hmmm glad you got those numbers for your ride...
only bolt ons I had on it before the cam where shorties, exhaust, electric fans, intake.and 1.85 rockers
and a nelson tune.
and I turned out a 258 on the Hp. so that would seem about right for you to turn a 250hp with a CAI and and HPPIII
what kinda times are you running?
