Hello guys ,anyone has experienced with the DC titanium race header ? I lost about 10 hp at 7000rpm and lost 4 hp at peak untuned (had no time to tune it)
Car spec is as follow : JDM ITR stock , JS racing intake ,port and polish head and intake manifold ,UNichip piggyback, SARD fuel press regulator,MUgen head gasket. The engine makes better power with the stock 4-1 header and 2,5 inch exhaust to the back with 1 muffler, i think that the short exhaust on the DC is just too much for the stock engine. AFR is 12,5 for road racing

 

same dyno, same day?

 

same dyno but different day, should i tune it on the dyno again ??

 

You have a stock itr motor, bolted on a "race" header and didnt tune it and wonder why you didnt make power? compression, cams, and tuning is key

 

Yes i know that, but long time ago SCC magazine did the great header test on a stock B18 and it gained 15hp forgot the torque gain though. Guess i have to get a more powerful motor to match the header

 

My guess is it may need to be tuned to your setup, a header isnt as plug and play as people make it out to be, why spend $1500 on a performance part and not spend a couple extra dollars to maximize your investment?

 

I dont know why people continue to buy DC crap. They usually only make minimal power on a large price tag and the constuction is poo.

so many better headers out there

 

Basically the result on the great header test on the SCC long time ago and the lightness made me buy it, its a good quality piece though and i love titanium . Had no time to tune it bcause i need to go tot the track to qualify.

 

I would think that if you tuned it ,It will probably run better.I don't think someone is going to spend that kind of money to build a POS.I thought the Ti header was a copy of the itr header.

Hmm..yeah i think with cam gears it will do better, now i have tear the motor apart for maintenence.Also im getting it modified but still not sure what setup to run, BTW what is POS ? And the TI doesnt look like the ITR header... will try post pic but how ?? Its not 10 hp btw more like 20 hp after i looked at the dyno result
