i was wondering how much horsepower i could get out of these mods and how fast it will go. Edlebrock carb, Pro Curcuit T-4 exhaust, stage 1 hotcam, rev limiter, twin air filter, 16 tooth front sprocket, with a 416 kit, with a port job? Are all these mods worth the money? And are there any more i should get or are there any i shouldn't get? Any info would help. thanks.

 

if you only want a slip on exhaust, i would recommmend ct or hmf. the ct will not be as good looking and it will be louder. but it will probally produce more power than any other. the hmf is a great quality pipe with good power gains. i would get a fcr carb instead of the edlebrock. stage 1 cam should be fine. for riding in open area, the stage 2 will probally perform better. if you are worried about lowend for trails or tight areas, i would get the stage 1. i know with the stage 2 cam a rev limiter makes a difference. this cam likes to be at high rpm's. my friend has a stage 1 and he never hits his stock rev limiter. the rev limiter won't increase power, but raise the rev limit. the twin air probally won't flow any better than stock. if your stock filter is in good shape, i wouldn't get a new one. by the way, i like my uni better than my twin air. i like my 16 tooth sprocket. just make sure you get it ported by someone that knows whats going on. a cheap port job can actually hurt performance. you will have a big power increase, especially in the upper gears.

 

you would have around 35hp or something like that. so it would run a lot better then stock. you could definetly tell a big difference.

but fcr carbs would definetly be better. you might push 40hp if you get all of those mods and a full exhaust system. it's hard to get a lot of performance out of a 400ex. I'm thinking 35-40.

 

is there a place you would recomend for me to go get it ported at? and how much is it? and would i need to change the rear sprocket?
