need more POWA SP63 5th port kit

hey guys, i just finished up tuning with Purple Drank. car is running great. i feel like i'm going to get tired quick of the power though.

i'm maxed out on 93 octane. i have no access to Ethanol

new forged short block
cst4 turbo currently 23psi target
cpe catted downpipe
magnaflow catback
methanol injection kit

i don't want to rely on the meth kit for power adding. i was looking at the sp63 5th port kit. anyone have experience with this kit?

wondering if the 5th port kit and my setup could net some more power, maybe ~450whp

it's a daily driver and i need to pass emissions. so aftermarket intakes or 8 port is out.

 

Getting 450 from the CST4 on 93 will be a bit of a task. That 5th port kit is solid and will easily fuel the car to that power I am just not sure the CST4 can make that jam on 93 without some ethanol timing. If you add methanol to that as well you could likely get some more timing safely but adding 5th port and meth seems like a recipe for a lot of work. You might be able to add some meth to the tank itself this would really be a better question for Purp Drank. @Captain KR You should also check out the videos @Sho has posted here from Will's talks.

 

AFAIK, 440whp is still the CST4 record on Luke's built motor with a whooole lotta meth spraying.

 

thanks guys.. i did hear back from Will he suggested methanol injection would be best. the ~450whp was just a guess. if not doable. then just max out CST4

 

Meth is definitely the easy way to do it but I have heard to many stories of pump failure and maintenance headaches. If you keep on top of that you should be just fine. PI is much more reliable but it comes at a cost and won't give you the timing headroom meth and will unless you add ethanol.
