a couple of weeks ago as my car was at XS engineering for a power FC install, they dynoed the car at.....approx 240 hp... https://www.nopistons.com/forums/pub...R#>/unsure.png which kind of surprised me actually...here's whats on the car so far



-mild street port

-hks downpipe

-blitz nurspec catback

-adam c's intake mod

-power FC

-Apex'i bov

-Koyo radiator

-NGK spark plugs

-ACT Single Plate clutch



the car is kept to 10psi, no boost leaks



i would expect, with the above for the hp to at least rise ABOVE stock levels?? https://www.nopistons.com/forums/pub..._DIR#>/sad.png would the power drop so much after around 90k on the chassis?



could there be something i'm overlooking? the catalytic converter is still stock, as is basically everything else, i haven't replaced the intercooler and i'm in need of an oil change, but i don't think that would make a huge difference....



thanks for the help!



anyways here is the dyno sheet

Does the motor have good compression?



Its not that bad, all you have is a DP+catback..

doesn't sound low. stock is 217rwhp...mild street port, some intake and exhaust.



remember stock rated levels are at the flywheel.

maybe the cat is busted up. I have dp, high flow, RB cat back, Pettit intake and SR intercooler. Put it up on the dyno and did 250rwhp. Removed the cat, poured out the crap that was already busted up from years of rotary abuse and did 307. I would imagine with a properly flowing cat I could have still done 280 any way.

not bad at all for a seq car...and mail order tuning.

i did 245wrhp with a dp and efini ypipe, somethings not flowing somewhere, i thinrd the main cat

240hp at the wheels is good for your mods
