running draw though

Iv done a little research on this and found good info on it but was wanting to know how well it works for people running over 400whp. Iv read that idle can be a little more irradic but there is less hesitation when you press the gas then running draw through. Anyone have any problems with it or suggestions, is it worth it to switch over?

I haven't found any idle problems with my blow through setup. I went with it because it was easy to fab up with a lightning maf element.

could I run the filter straight off the turbo compressor side or do I need to run some piping in between the compressor and the filter if I switch to blow through.

Filter right off the turbo. Also place the BOV before the maf and u can vent it without any problems.

i love my blow threw. ive got my AF right on the comp housing. theres just one general rule of blow threw that ive followed, and thats have the MAF 12" before the TB, and have the BOV 12" before the MAF. its recomended that you have at least 8" of straight pipe after the MAF and before the TB to reduce turbulence.

What do you with the vaccum lines when you go to a blow off system? Do you run them off the intake before the tb like stock or do you run them off the turbo intake? Sorry if its a newb question im new to this turbo stuff.
