Thread: grinding down the H bar in s/c????

hi guys, on the build thread on here... on how to mod ur LIM and s/c for an intercooler ....it said that grinding down the "H-bar" helps with the cooling of the s/c i guess.

is this still an accurate/proven/good mod to do?

i dont want to do it and lose boost or something gets messed up. ive searched around, seen alot of videos and havent seen anyone showing how to do, or posting about this mod.

its a 2004 gtp xpz cam, head work, zzp hd trans, full sized intercooler, i just cut the LIM open, and some big O 22s that spin like **** that make all these mods non extistent lol

Only thing that might help is smoothing up the inlet.

I always thought removing the h bar was good for intercooling

wish someone would step in and explain why it is or why its not ......im thrown off by it because i read in other thread that air being forced through the port is not going to change direction going through the ports so im "guessing" that means the air is going to shoot straight down through the intercooler into the LIM, before it would have a chance to float over into the area pass the h-bar

on the other hand im thinking its more about more of the intercoolers surface area being available to the incoming air...and regardless of the air pushing through at one end of the supercharger...the incoming air will be subject to a lower temp due to more available intercooler in that outlet............

iono someone explain it to me

Here's a write-up that even shows removing the H-Bar:

*As a side note, remove the 22's. Get 18 or possibly a 19 inch rim. Anything over 20's on these cars, look like ass.

im def going get them 19s ..i agree i was pressed for them a year ago and then i was like wtf u can roll a small bowling ball under this thing if the exhaust was removed smh.....

i seen this thread i just wanted to be sure cause ive only seen that one thread...

Not to mention your speedo would be correct if you didn't reset the PPM in the tune.

Your def right imma prolly going do 18 19 tho ..wanta upgrade brakes in the future

Thanks for that vote of confidence ...I'm already grinding away ...it takes waaaaayyyy to long using a dremel
