well this could just be me being ignorant when it comes to turbo hondas, but why does my car sound like it has a lawn mower blade on it? seriously, it sounds like im ridding around cutting grass.

would it be because i have an external wastegate?

i'm pretty sure there isn't an exhaust leak.

i just wanted to make sure there wasn't something more serious going wrong

mahcivic

um more specifics would be great

My sound like that sort of, turned out it was a bad gasket that was fluttering a bit!!!!

stargazer

maybe because the motor isn't that much larger than a lawnmower motor?


and you better take your *** back over to cc.com and post pictures of your finished setup!

probably the external wastegate if you have an atmospheric dumptube

rustdha1o

alright..

tial 35mm wastegate
lovefab.com manifold
450cc's w/ s-afc hack
custom downpipe
fmic from johnnyracecar.com

anything else?

in low rpms (1-2.5k) it sounds fairly normal. like a n/a car with Apexi N1 exhaust would sound. when i step on the gas, it sounds like it's fluttering quite a bit and its pretty loud.

stargazer: :P i'm getting there. it's not finished so i'll be sure to get pictures posted when it is.

whitey: that's what i was thinking, but i wasn't sure. i didnt think the wastegate opened up until higher rpms.

its your wastegate opening. Pipe the dumptube into the downpipe and your problem is solved. (If its the sound that I think your talking about)

rustdha1o

hah that would be nice except i dont think i have much room to run another pipe with my a/c being right there. ill try to figure something out

put a lawn mower muffler on your dumptube

does it sound like that only when you accelerate before boost or after... cause if it makes it before you hit boost you probably have an exhaust leak... and if it makes it after... its probably that your wastegate aint hooke up to nothing to quiet that bitch down...

I had a cracked manifold... and it sounded like a shitty lawnmower for about a week till i fixed it... its really emberassing... just like when your brakes squeel...

check for black soot... and thats most likely where the leak is
