i got a bone stock evo 8 i had it all modified but recently for the past 2 -3 months i have been driving it around with a walbro 255 pump as my only mod and when i take some pulls here and there, i can smell rotten eggs and a weird burning smell. could it be that my fuel pump is causing this smell? too much fuel?



also only mods i ever had in motor was bov, intake ( intake i still do have along with a evo 10 bov ) and HMBC, thats all.

 

its your clutch.

and i suggest you take the want to buy stock fuel pump out of your post or you will get points against you and your thread closed

 

how positive are you ?

will the walbro affect anything if i have it as my only mod?

 

lean condition would cause that smell. or your cats burning up

 

fuel doesnt smell like rotten eggs, and if its your clutch you better look into adjusting the clutch master cylinder, because it is being burned up if so.

 

also i have never tracked the car and it has 40 k miles on it never beaten on. that really does suck if it is the clutch. thanks for the input guys.

 

the only thing ive ever heard of smelling like rotten eggs is a clutch burning up. how much boost are you running? I doubt enough power to overpower the stock clutch, but if it has 40k miles, it could be going out.

 

a burnt clutch smells like burning brakes.

 

unless the the clutch is an organic eggshell clutch.haha!!!

 

i beg to differ. the clutch in my vr-4 went out a couple years ago, and thats exactly what it smelled like.

 

thank you for the advice. on typical driving it doesnt smell at all but just hard pulls i can smell it, didnt think my clutch would go out so soon its one thing after another with my car.

just want to get rid of it now.

 

90 weight oil smells of rotten eggs. When is the last time you serviced the xfer case and diff?

 

never lol

i havent done an oil change in a long time either which reminds me to do one coming up soon.

i had a tranny flush done not too long ago.

 

its either clutch and or a clogged up catalytic converter(that is if you still have a stock one on) I smellt this all the time with our squads. Everytime you mash the throttle you smell rotten eggs coming from the exhaust.

 

Rotten egg smell=bad cat converter 9 times out of 10.
