For some reason manufacturers are still feeding people this line about how ELs give more power and UELs give more low down torque. Most tuners who see a lot of these however, are getting same numbers up top with a good UEL as any given EL but with more torque. Bob (Driftoffice) and Vit (VitViper)both seem to get their best numbers consistently out of Tomei and its derivatives. For me, I had a Nameless and my Tomei eats it alive literally everywhere. (that's a lie, there is an area from 4100-4200 where Nameless has about +3 ft-lbs, but I'm +40 at 3500) Same dyno, same baseline, It did exactly the same as the Ace 350 on the same fuel with a little more torque. And for you to make a statement as broad as "el headers make power from 3500 to redline" makes me think you might not know what you are talking about. Every header performs differently and 3500 is smack in the middle of the torque deficit on most equal length headers. Give this a read http://blog.vittuned.com/just-a-coup...-vs-tomei-uel/

From what i have seen, i can say this statement is fairly accurate. After having all kinds of headers on our dyno none stand out with +/- 3 HP or more. |

Like I was saying earlier, the biggest difference appears to be at the low mid range while peak numbers are very similar. If you look at Jonse's dyno you see the lowest point in the torque curve is after 3600 closer to 4000rpm. You'll tend to see this in most of the EL headers. On the UEL dynos you'll tend to see the lowest point before 3500,and the dip is typically less pronounced.
For me the dip in power at 4000rpm is very annoying, but it might not bother others. Driving around town, if I'm revving up to 4000rpm i'm probably trying to accelerate quickly only to be met with a drop in power. I think that should be your biggest consideration in terms of performance as that's were the largest difference is between the two types.

Very fair.
My car is 97% track car, so it is very annoying if I am ever below 4,000 rpm. Plus after tracking the car I don't care much about playing on the street and the power is still substantially better than stock everywhere.

Are you talking about the HKS header + front pipe combo. There's no OP portion like the Apexi system. http://www.hks-power.co.jp/product/8...ust/index.html http://www.hks-power.co.jp/product/8..._manifold.html Because unless I'm reading the info wrong, there's no overpipe in there.

Tomei vs HKS headers for gains?
Quote:
I recently had my car tuned on Dyno Jet with FF kit at Moto-East. Setup is Tomei UEL, Crawford BPB, Namelesss Resonated and Catted OP+FP, Greddy Supreme SP CB. E62 at the time of tuning and max out at 198whp for DD tune. '13 BRZ with 60k miles. Previously tuned with OFT Stage 2. I noticed that your chart shows a torque dip between 3000-3500 rpm. I don't know much about tuning but it's pretty obvious that UEL seems to fix the torque dip issue. I might be wrong but the numbers are pretty obvious.
