well as many know i have been testing some mods lately on the ol yukon

mods ::::: Pacesetter LT's hooked into factory y-pipe, single in dual out flowmaster into stock tail pipe,20's dyno 249/279


efans installed 255/281


started tunning with the HPT made 4 changes 2 AFR 2 timing


final number's for today are 264/285 more tunning to come got an exhaust leak and i have a nice split in the 02 reading in the scanner at WOT and the laptop went dead also


still got my CAI kit, pulley and a lil diff exh setup to try out with alot more tunning to come with it

 

great results! thats cool to see what your mods are making.

 

6hp and 2lbs of tq, mine was 2hp and 9lbs of tq go figure. 264/285 is right in the ballpark, i would expect a little more with LT's but good never the less. I hit 265/298 with handheld/ wide band/e-fans/and cat-back.

It is nice having dyno's for each mode, takes the guess work out of it.

 

Nice numbers! It's cool that you're doing this man, not too many people will take time out to dyno all of the bolt-ons seperate.

 

It's funny how e-fans give so little power yet were able to drop me 3 tenths in the quarter.yes i know track conditions blah blah....i know.But still just doesn't seem like they would help that much wihile giving such little power.But hey if it works it works.

 

im just glad i dont spend to much money in dyno time $$$$$$ it pays off to help the shop owner in your spare time when he has dyno days and such



next go around is a UPD air lid with a with a custom 90* rubber elbow and then a few more tunes i allready have written up


after that it will be the UD pulley hopefully

i will keep you posted on my quest for 300rwhp on the 20's

 

this is the efan pull and final pull of the day after my HPT tweaks
