when vtec pops on my car some blk smoke comes out... i wanna kno if i should worry about it or not or what it could be...my car is runnin str8 pipes,has fpr,msd so i was wondering if that could be the problem as to y the smoke is comin out.. maybe its running rich???

 

 

black smoke is fuel.
since you have fpr and igniton, and straight exhaust your just running rich and it is unburnt fuel...not to big of a deal.

iite thanxz... my boy told me the same thing but i jus wanted tosee what other people thought

 

I hope you have a fuel pressure gauge if you have an adjustable FPR.

 

When I had my old 189k mile GS-R dynoed, there was a noticeable amount of smoke coming from the exhaust when VTEC engaged as well. The tech said it was normal

 

Well i wouldnt say it is normal for it to smoke when vtec kicks in, but it is common with these engines. If the car was completely healthy it wouldnt do it.

 

ive seen stock vtec cars do this. its typical honda top end smoke

Well as strong as it was, it did have 189k on it... I suppose he just meant "nothing to worry about" when he said that.
