HT: We'll look at the head in the next episode, but since this is a complete "system" type approach you're modifying the entire combustion chamber. What if I haven't sent my head to Endyn for all this matching? Will the Rollerwave pistons still do their thing?LW: Absolutely. I think we've got 45 different B-series pistons on the shelves just so we can make the best match for whatever combination. One of the reasons we don't have online sales is because being able to talk to customers and discuss their respective engine modifications allows us to make sure they get the ideal piston for each application.
HT: Makes sense, but I don't see a piston production facility in any of the pictures on your website. Whose pistons are you using?LW: We use our own. We don't make them: Wiseco makes them to our spec and ships them to us just after machining, and we do everything else. We can alter compression ratios here by machining the piston tops, and we hand radius all the edges, providing a brushed dome finish before balancing each piston. We even do our own coatings depending on the application. With all the Hondas and now Toyotas, Nissans, and Hyundais, I think we have nearly 100 truly custom pistons available. Using our Roller-Wave design pistons, you can generally run one full point more compression than you can with any other piston without correspondent detonation.
HT: Almost forgot the pan and the oil system-you rework the pump or something? Do you put in new gears?LW: No, I haven't seen a set of aftermarket gears that are worth a shit. The Honda ones work fine-we just measure everything and set it to minimum Honda clearances. That means less oil goes around the gears and we get more pressure by tightening it all up. Enlarging, radiusing and polishing the oil inlet and outlet passages also helps a great deal for flow and overall pump efficiency. The other thing we do is a custom bypass spring. We have 3 of them and we'll install the one that matches the engine best. As for the pan, I've tried a lot of them, but right now I'm using the Moroso drag race pan. We weld in a baffle all around the pan's sump area that prevents oil from climbing out under high-G situations. Combined with a modified factory windage baffle, it's a really tight fit, but works great.
