FA5 with 06 TSX cams, dyno sheets.

i decided to clean up this original post, alot of dyno sheets now with diferent combinations...

reason for all my dynoing, well my AFR's were a little lean, so im just tryin to get it all straighten out now.

here is a direct comparsion of my car and a Stock Si. stock Si's put down low 170's on this dyno, this SI put down 174WHP with 131 lbs ft, i put down 199WHP with 139 lbs ft of tq
my mods are
fujita short ram
P2R spacer
ported DC race header
NST pulleys
hondata IMG
hondata reflash
06 TSX cams


dyno jet figures with all my mods that are listed 211WHP



the scary AFR on my car with all the mods listed above



AFR on a stock Si



the AFR leans out just right with the CAMs... so what was the problem? FUJITA SRI was letting in to much un metered air and causeing it to lean out over 1 FULL point vs the stock airbox... my findings are the diameter or the fujita is bigger than the stock airbox... and the dividers that the factory airbox have are there for a reason... i got nothing but consistant AFR through the whole power band with the stock box..

here is the fujita SRI AFR vs my Stock airbox AFR



next graph here is all mods listed above with the exception of the P2R spacer vs NO spacer and NO fujita short ram...(stock box) look closely, i picked up 2 lbs ft of tq but i did lose about 8 WHP with the stock airbox but its only over 7500...



dynojet figures fujita VS airbox.... 208.9 WHP with SRI and 201.3 with the stock airbox.



ALL THESE FIGURES ARE SAE CORRECTED!!!!

here is all the cam info again

******** cam part and price info from acuracarland.com*********

14110-RBB-A00 CAMSHAFT, IN. 1 2006 TSX list 420.48 there price 336.38
14120-RBB-000 CAMSHAFT, EX. 1 2006 TSX list 439.13 there price 351.30

DO NOT BUY 04-05 TSX intake CAMSHAFT they are not the same... they have less lift and duration on the highcam lobe.... "14110-RBB-000 CAMSHAFT, IN. 1 2005 TSX list 439.13 there price 351.30" its more expensive too...

Would be nice if you could dyno before the cams as well. Every dyno is different, so having a baseline would be useful. Also interested to see the change in the A/F ratio.

Holy crap subscribed. :popcorn:

Dynojet = garbage. Get a real dyno, like a mustang. Haha. Dynojet projects about 10-15% more horsepower than you actually have.
That's the only dyno i have every used is a mustang.

A dyno is a dyno. Everyone knows what they are. You can calibrate any dyno to project more horsepower. Im just saying dynojet sux.
what ever you do, use the same dyno before and after. Who cares what kind it is, we just need consistancy. This sounds like a kick ass idea. Get those numbers up soon. Before and After.
