Question Need help on hp or 1/4 est

Whats up, I have an 04 wrx with an sti motor swap, 255l fuel pump, vf 22 18psi, 565cc ing, uppipe, 4" downpipe and TXS cat back, ecotek tuned 93 oct.. And a 5 speed sti v6 type ra gearset. I have'nt been to the dyno yet, but im looking to get a few 1/4 mile runs in next week. Anyone have a similar setup with times or an estimate? Thanks.

You have done a ton of work to never have had the car on a dyno! By "ecotek", I assume you mean Ecu-Tek? If so, you did need to have a pro tune the ecu... did you do a mail in reflash? I assume you did because most other vendors who can tune with the Ecu-Tek reflash also have a dyno for you to put the car on.

18 psi on an STI motor will probibly give you about 285 whp. You might pull a sub 13 quarter mile - thats only going to happen if your a good driver. Most likely you will pull 13.2 or so at 104 mphish.

Your set up is kinda interesting with some things that don't add up. I hope I am wrong.
