I am tryin to decide between the shaner s2 or s3? Iv'e heard that the s3 works best rolling and the s2 is more for a jump of the line.

 

Well, if there is a difference, then it probably should be based off of what type of driving that you do 90% of the time.

 

I know someone with the S3 and it is too big, and it will cause hesitation a low rpms sometimes.

 

I hear the two kinds Shaner ports have different shapes to them. In other words, one is more aggresively sculpted than the other, but he would have to verify that to say it's ok. For sure most instances you could just say the S3 would be the one with the greatest hp.

 

link to his site? pm me with it if hes not a sponcer

 

ok yea, that makes sense... but I would like to see a link too

 

either way your not going to see much power like maybe 5 rwhp if your lucky, same the cash, and buy something that will make more power.

 

The Shaner S2 will make a stock vehicle perform better in the 1/8 mile run and the S3 will make the same stock car perform better in a 1/4 mile run. The S3 is the choice for vehicles that have modifications. The best part of owning this type TB is the instant throttle response.

 

decided im going with the S3, i race the 1/4 and from rolls more then a short 1/8th dig

 

I have an S3, it's a work of art. He does the best job with the factory piece.
