I store mine in the garage for the winter.. But I run my 20G at about 16psi, and it spools up early enough to have power through most of the rpms..I can break traction in just about every gear.. And Ive also had 3 2nd gens and none of them have had problems with crankwalk...

Also, the 750's are a good choice.. You could even get away with the 650's if your not gonna be lookin at over 500hp.. I have 750's and to this day I still think its overkill at the boost that im running.. Mayb once I build the motor and start pushin what racerx is, Then I would actually use the 750's the way there suppose to be used..

 

i'd like to get mine on a dyno so i can tune it, theres none close here. I'll have to wait for the DSM shootout at norwalk i guess. Trying to watch the wideband while your sideways in 1st roastin all 4 tiresisnt really possible, 3rd gear runs down the highway are over too quick.
I hope you plan on doing a fuel pump and AFPR also or your 750's will **** like a 20 year old dog.

 

if you plan on going any bigger in the future i'd say 750's, if this is your final step and you are going to leave it alone... i'd say 650s.

 

yeah this will be a daily driver so I'm not looking for a real dyno machine or track terror. Dont get me wrong I will run my car . But I am looking for hp/weight ratio of give or take 10/1 maybe 9/1 so 320-350 awhp.

 

lookin for 320-350 i'd say go w/ the 650s

 

2nd that.. They would be plenty big and will support that hp easily..
