I don't know this engine bay too well since I haven't bought an ISF yet, however the designers have to take into account smog and other regulations.I can't believe both Lexus AND Yamaha accepted such a pathetic design for an exhaust manifold. Granted there's no room, then make the f one. Geez!
Those are numbers I would like to see. Perhaps we can crack the 400whp.I don't know this engine bay too well since I haven't bought an ISF yet, however the designers have to take into account smog and other regulations.
It would be pretty interesting to see the final product and the dyno sheets with Joe Z exhaust and intake in addition to the headers.
Considering I've seen 380 with the exhaust and intake, 400 is pretty much there once everything is installed/running.Those are numbers I would like to see. Perhaps we can crack the 400whp.
did you say not a big power differance?Here is a bit of a sneak peak! I have about 15 hours into what you see in this pic!! These things are tight! I was going for equal length, but I would have 300 hours into just one side if I go for that. Sooooooo........ I'm just going to do a nice flowing set of headers, I have done a bit of the math and it really shouldn't make that big of a difference in power. So here you go!
