how much power?

[snakecharmer96]

motor is in the shop getting a hot rod 4mil, weisco top end, 19cc cool head, stock porting, fmf sst's, stock carbs jetted up with k&n clamp on's at sea level. how much hp do yall think i will get?

Almost 50

 

You won't see the kind of gains you are hoping for with SSTs and stock porting even with the 4mil.

stock porting is not going to work well with this setup. and neither are the sst's. i suggest some proper porting and better pipes...otherwise you are basically wasting your money.

i forgot to mention it will be a 400cc but, what pipes will work best and what kind of porting do i need.

[snakecharmer96]

also, i am not looking for an all out drag top end motor, what pipes and porting would be good for significant low to mid with good power on the top.

If I were you I would get some toomey t5's and an eric gorr woods port. I've heard nothing but good things about his work.

To put that kind of money into it and not port it would be a damn shame. You don't need an all out drag port.

Some builders call it an MX port, some call it an aggressive Trail port...and I'm sure there are other names.

 

Jeff @ FAST racing, Jim @ Passion Racing, Eric Gorr are all a few good engine builders and come highly recommended on this site.

 

You do need a better breathing pipe.

T5's are more all around.

 

Shearer, CPIs and Rockets are more geared toward drag, but...they will make more power on top...period.

 

Don't forget two EASY\Cheap mods, if you haven't had 'em done already.

Timing plate from Ricky Stator AND a lightened flywheel.

 

Ask who is doing your engine work what pipe they recommend. If you go the porting route, which...you should...I'd ask that builder.

Tell him how you want to and where you ride. Talk to them about what kind of power you want to make, and they can tell you what kind of porting and pipe combos should work best....

with a 4mm crank you are increasing the stroke so you need porting to accomidate the added stroke, that is how you get the most power out of a stroker motor. you would benefit more with an midrange pipe and an mx port.
