Default 370's

heres my question, i was talkin to the a little birdy and he said that 370's were 5x13's. and im wantin 5x14's and a 62 charger for my truck but he said dont waste my time with 5x14's. he said go 5x16's. i thought 5x16 are wayyyyy to big but idk? does anybody know what 370's are and if 5x14's would be a waste of my time/money. also would 5x14's be to much for a 62. thanks

i have 5x14's with a 62 its a good combo. 370s if im not mistaken are a 5x.012. and yes 5x16's are a huge injector my 5x14's give me so much fuel i cant hardly keep the smoke down as it is. if you are going with 5x16's you would want either compounds, or a MONSTER single. a 62 wont cut it with 5x16's. all the trucks run differently so it might work better for tohers than it does for me. but i would stay with a 5x14

they run real well i get a little haze at idle but not horrible. on the VE pump i could see like 1300 at WOT with alot of pump mods and the phat shaft charger. before that charger on an hx40 i could see like 15-1600 on them. i havent been able to get the p pump running yet so i cant tell you as of now. and i havent ever towed with them but they were definitely smokey.

The smoke is a haze at idle,nothing to bad.
Daily driving you can control the low end smoke with your foot.
At wide open throttle they will black out an entire highway and turn daylight into night.
EGT's are higher than stock and they would depend on what charger(s) your running.
On my 12v which is equipped with a HTT Pro-Street 66/71/13ss at wide open throttle on Yesterday's dyno rips the highest I seen for EGT's was 1450 and that was in 70 degree air,with 99% humidity and no fan in front of the truck other than my Flex-A Lite's.

As soon as I find a good place to put the video's from yesterday I will post a link so you can see how much they turned the owner as black as the soot itself.I had a tough time videoing the runs with the winds and on each run I moved and still ended up getting soot shotted.

here is another vote for the 5x.014's ... 5x.016's are a big injector, my s465 still doesnt clean them up
