even an ITR motor wont make 230whp. Not on Mainstreams Dyno which is what i go by because i have the most experience with it.
Also, you have to remember what gear the "Ks" Dyno in effects power numbers too. 6 Speed throws a lot of stuff out the window and effects the shape of the curve. MOST B series dyno in 3rd gear if they are NA, and 4th for the last run because its as close to the 1:1 everyone talks about.
When you change final drives, gearing, it effects peak numbers and the shape of the curve.
Thats why a TON of H2B cars with relatively NO mods make tons of power. Ive seen STOCK H22s mated to a B16 trans make 205-210whp. Numbers no other REGULAR h22 is even CLOSE to making. Wonder why ..............
2 things about your statementOriginally Posted by Moseley
1) I find it incredibly hard to believe that SSR made a header with such SHORT primaries and such small Diameter for a "k24" motor. The header evan has is an OFF THE SHELF Tri-Y Header, they may have told him or someone else it was custom, but if it is, how come it matches EVERY OTHER SSR header EVER sold for SWAPPED cars?
Dont believe me? Check out their own site.

See where it says at the bottom:
Danny for 90% of his customers only makes 1 header. Ive seen them, ive BOUGHT THEM. Evan doesnt have some custom 1 off piece that was special made for a 2.4L. Its the NORMAL REGULAR K Swap Header SSR has been selling for YEARS.Every header is custom made in house and we have designed our headers for both the K-20 and K-24 engines.
These photos were taken almost 2 years ago by ME when i worked for Batlground. Notice how my the "replica" header is IDENTICAL to the SSR header. Everything from cylinder pairing, to diameter, to length etc. The ONLY difference is a SLIGHT angle where the header connects to the exhaust making it touch the rear subframe.
You guys can make excuses all you want, but it doesnt change the fact that a TUNED $1000+ header LOST to a $450 header.
And to answer the question, yes , the bigger primaries makes the Skunk2 "Replica" header make more power. Thats obvious when you look at both pictures. The SSR header was designed 3-4 years ago, Skunk2 designed their about a year ago. So obviously they found that bigger primaries performed better on a 2.0l motor than the old SSR design.
If SSR has some fancy new design out now, AWESOME, i could care less, because MY customers are going to pay $1000+ for a header that will BARELY make more power than my header that costs 1/2 as much and is shipping SAME DAY.
2) IF evan has some K24 header, designed for a BIGGER displacement motor, are you telling me that the REGULAR SSR K20 header has even SMALLER primaries? Gimme a break. The only thing that MIGHT have been different is SSR made the K24 header slightly longer because of the deck height differences. But his header is not custom engineered for a K24 like you claim. I have a REAL K20 SSR header at my house we can do comparisons if you want, ill bet you EVERYTHING is the same.
