sorry couldnt put the picture coz my scanner is broken. neway kinda dissapointed i was aiming for 200+hp but 1st run was 187.3hp and 168.7tt/lb. final run was 196.7hp and 175.3ft/lb. i have jrsc 6psi, aem short ram, greddy sp, and apexi vafc 2. its street tuned and vtec is set to 4500. the tuner said that u would have reached 200+ if i upgrade my header. im running on stock header for now.

 

Yeh, the stock header with a 2" collector does plug stuff up a bit. Not sure if Kamikaze makes a 4-1 for your car but they work well on GSR SC'd engines. If they make one make sure it has a 2-1/2" collector.

 

by the way, measurements came from the hub, not from the tire.Dynapack 3000 dyno

 

ouch man. automatic?

 

damn i find these really low stock header or not...

 

the result is so dissapointing. its manual. im buying a dc stainless header. im gonna dyno tune it again.

Yes they do, and if you look hard enough you can find one for cheap

Nah dont go that route, DC sports headers are made to work with stock cat thus 2.0inch collector which sucks for a setup like yours, or any other setup at that. Look for a kamikazi header

why's the ratio so high at 5.8? i'm not a dynapack expert but shouldn't that be the FD ratio?

 

Running FI with stock header is pointless, all that power is being choked up by the small 2 inch collector. Get the Kamikaze header and do another dyno run, you'll be surprised.

 

What's up with max power coming in at only 6200 rpm?

My max power with the JRSC was 249hp @ 7400 rpm. (Stock header by the way.) Have you done a compression check? You do have an H22 A4 in there right?

 

yea h22a4. i will buy a header and get it dynod somewhere else

 

is kamikaze header carb approved
