i meant the hx35.. i fat-fingered it.. haha.. that WH1C has a much bigger exhaust housing than the HX35 doesnt it? good idea on using the valve for a flapper.. i used an hx35 on my supra a few years back.. held 26psi nicely however without an external gate, that thing would not hold anything less than 26. it made TONS of power, no dyno but easily in the 450 rwhp range considering my clutch wouldnt hold rated at 510lb ft.. however the small exhaust housing caused egt's to climb too high and damaged my ring lands. ahh well.. very aggressive turbo. full boost came on violently.. hits very hard.. i liked it
also, can you send me a few more pics of your manifold? i'd like to see it in a little more detail. i'm currently working on my own, but yours looks great. and if it's a good price, i'll scrap my project and buy yours. also, what type of t-body?
