Im running a dry nitrous 100 shot. Im using a msd window switch setup at 2800 and 6300. also have a walbro 255 fuel pump. It runs flawlessly and very smooth. Car is a 92 sc400.

Right when i was going to get rid of the sc400 for a supra i have a new inspiration! Motor looks incredible! Keep us updated.

re 600 mil/min=600 cubic centimeters/min

I prefer dry for small shots say up to 80-90hp. Over 100 id go with a direct port. Direct port provides a equal amount of nitrous/fuel into each cylinder versus a dry which can vary per cylinder.

Mine has been able to handle 90psi ..with no problems.

I agree...i would go with the high pressure walbra 255lph that Lextreme sells. With the rising rate fuel pressure regulator at a ratio of (10:1) at 6 psi your going to be pushing the fuel pressure to about 98 psi at 6lbs of boost. Running that much on the stock pump all the time will shorten...

re Ill take pic when i get my camera back from my brother. Im running a msd window switch set at 3000 and off at 6000. Also have a walbra 255lph hp and one range colder autolite plugs. Only problem is that when im spraying it doesn't want to upshift around 5500 rpms...it studders. Im going...

re Im running a 100 shot nitrous system w/ msd window switch set at 3000 and 6000 rpm. Ive changed the plugs to one range colder and gapped them down to .040". Also changed the fuel pump to walbro 255lph high pressure. Car was running great but is having a hard time upshifting at 5500 rpm...

Everything worked great!! 80 shot feels great!

im running a dry nitrous kit that requires the oem fpr vauum signal to be taped in order to rasie fuel pressure through the nos fpr. So can i get away with tapping the last fpr before the return? Shouldn't that raise pressure through the entire fuel raise (left and right)?

if i dont want to eliminate the pass. fpr do i just tap both of the vacuum signals?

When im done w/ my charger project im going to use a rising rate fuel pressure regulator to increase the fuel. Do i tap into both of the regulators vacuum lines (one on the drivers and passengers) or only the one on the return rail (drivers for us spec sc400)?

Im running NGK BKR7es-11 (Gap at. 040) and they are cheap and provide good power w/ my nitrous. Also used the iridiums BkR6eix-11 and they were also very good.

i agree no way the stock filter outflows the K&N. Im using the K&N w/ the BFI and its a noticible difference. Plus i never have to buy another filter again. Just clean every 6 months.

re I got mine from ebay..was like 100 us dollars...magnaflow 2.5 xpipe. Went with a full true dual 2.25" piping and x pipe and 2 magnaflow straight thru mufflers.

re would your brackets work with other centrifugal like powerdyne or ATI? I want to run something similiar to yours but use a blower that is self lubricated so i dont have to tap the pan for oil. Do you know if the bolt patterns are similiar. Also are you running the charger clockwise or ccw?
