Here is an old test we did comparing the Skunk2 Alpha header to the PLM Toda replica. When you're all motoring life away on a budget and need a shelf header, these 2 are hard to beat.
The basics of the engine are as follows
- PR3 Portlow head on Skunk2 Pro3's
- Modified PerformerX intake manifold
- 3 Inch Exhaust dump
- Hondata S300 on e85
RedLine is Toda Rep
BlueLine is Skunk2 Alpha
Tested on the same day minutes apart. No matter where we moved vtec or played with a/f and timing we couldnt get rid of the midrange lumpiness. I'll go ahead and assume its due to the cyl. pairing. Either way it rocked out on the very top end. The quality is real nice and it fits really well.
This was enough power to go 11.2@120 in a tin can EF.
