hey all.....after my sudden introduction to engine failure caused by the water/meth failing on the dyno at WOT, I am considering losing the WM. what I thought was to run a safe 6-8 psi tune for the street on 95 pump gas and then using C16 or similar race gas for the strip to 18psi ish. would...

things were going so well on the dyno when the water meth decided to fault. we were about to do a graphed pull when this happened. shut here down right away and thought things were all good. on restart smoke started spewing from the breathers and, well the rest is history. we were at 643 hp at...

ok....apart from my turbo oil leak it feels like my converter is slipping. when I took her for the first rad test I thought the trans needed more fluid, but no that was all good. the shifts are softer than I would have expected also. my converter is a 9.5 ptc 3800 stall. 410 sb, s475 turbo...

hi all, I've been lurking around the forced induction forums for a while now checking out other builds and gathering info for my build. I am a few weeks away from first start up so need some advice on a few things I'm not 100% sure about. I'll start with my combo.... 360 + .040" Eagle 4" forged...

well, time has come to start assembling the 360/410. I have always run a pair of ported 360 smog heads with 202-160 ss valves and comp dual springs. these are 65cc chamber and 9-1 cr . yes a s475 turbo will be bolted on. I am contemplating putting new heads on the stroker, but not sure which...

do I need to consider block fill. my block is back from the machine shop ready to assemble. machinist said that if I do low fill the block, that he wants it back to check bore. I never considered this at the beginning, just something I mentioned when I picked my block up. from what I have read...

well autumn is here for us and have decided to remove the Vortech and replace it with a S475 turbo. should be straight forward as everything is in place for boost. been poring over the info here and all I can say is wow, this forum rocks with info. anywho, this is for a 360la/727 in a '70...

what plug gap should I have with V2 Vortech. plug i'm using is a NGK BPR6ES with 35 thou gap. cheers

hi all..... having gone to the Vortech from NA I must say the results are impressive. Ran mid 14's on the 1/4 NA and PB of 11.67 with the supercharger. Same engine, trans, gears. Off the line she seems a bit sluggish to the sixty foot and then off like a scolded cat. Rear gears are 3.5:1, 26"...

hi there....I have been using the car with unboosted brakes, but have now put the booster back in. am running vortech v2 on 360 sb. what I need to know is what affect if any will boost have on the affective operation of the power brakes. will it be necessary to put a non return valve of some...

hi.. anyone using these? are they worth using. i'm pushing 10 psi into my 360 via a vortech v2. have just had afr's sorted on the dyno where the dude thinks that a knock gauge might be worth the while installing. cheers

hi all.....i'm about to fit up a Vortech V2 SI trim blower in place of the powerdyne currently on my 360. would like advice on what size pully to run on the head unit to acheive 10-12 psi boost at say 6000rpm. crank pulley is 8". cheers

hi all.....has anyone had much to do withe the XB1. just wondering if they are any good as it would fit the BD11a brackets on my 360. i think they are oil fed so head unit would need to be in what position? cheers

hi all, have powerdyne bd11a on a 360la motor. i hear that superchargers like more cam lsa around 114. is that correct. 360 has comp xe268h at the moment which i think has a lot less lsa. so is there a cam out there like the 292/509 purple shaft that will work better. i would be limited to no...

hi all, where is the best place to plumb in the boost referenced fuel regulater? on the carb hat, the supercharger scroll? also same for the bypass valve and BTM cheers

been looking on ebay at a possible turbo option for my 360. is the gt45 1.05a/r suitable as a single turbo setup. i'm not wanting to brake land speed records, just a tough reliable streeter with some track time. reluctant to use my powerdyne and everything else is already set up to run. cheers

hi all....well it seemed like a good idea at the time. it was all but new and cheap. when i started searching for info, most of it was horror stories about peoples bad experiences with the Powerdyne and or parts and services suppliers. it's a BD11A that i have and have already upgraded the...
