Default New 1/4 mile video SC400 12.08 @ 114.98.

Ran at Zmax dragway today. Best was 12.069 @ 114.66.

Still running a bit rich with the Adaptronic but getting closer. Still figuring out the launch control. Has not been on a dyno to tune timing, I could probably run some more advance.

Added a couple of jets to my water / meth setup. Guess it helped because I ran 12.148 last weeked at a different track.

The run in the video was:

60 - 1.809
660 - 7.783 @ 91.21
1320 - 12.088 @ 114.98

The best run was:

60 - 1.796
660 - 7.758 @ 91.35
1320 - 12.069 @ 114.66

I ran 3 times, the other run was a 12.21, not sure what happened.

Pisses me off because I know I can do low 1.7's in the 60ft which would have been all I needed to run an 11 anything.

I basically doubled the amount of water / meth I'm spraying. I noticed at Rockingham last weekend that my intake temps were getting pretty high after about 7 psi so I added two nozzles. 1 before the supercharger and 1 after, the other 2 are after. Was dropping to about 85 degrees and swinging up to 140. Today the temp was dropping to about 85 and swinging up to 110, huge improvement and not bad at 12psi without an intercooler on a 75 degree day. I love water / meth injection.

(how the centrifical is mounted and whatnot) --sorry for all the questions bro. your car is killer. i'm thinking of just slapin an s-trim on my totaly stock ge motor. hopeing to get about 250-285 whp. what do you think? i havent found anyone with that set up yet. thanks man.

Hey man, just to clarify I have a V8 1uz-fe. You said "stock ge motor" so not sure if you knew that.

But, here are some current pics. It is a Vortech V-9 F-trim, 1 of the smallest units they make. Upgrading to a V-1/2 in itself would probably increase my power a bit.

I added 2 water nozzles. The 1 before the supercharger and the one midway in the intake pipe. The 2 that are close together are the nozzles that I've been running for awhile now. In case anyone is wondering, I don't trust anything to seal and I love Toyota's red sealer.

My ECU turns the pump on at 2psi currently and drives the 3 nozzles after the supercharger. I have a boost switch set to 6psi that turns on a water solenoid which then drives the pre-supercharger nozzle. I originally wanted to use the solenoid for both of the new nozzles but the pressure in the intake pipe pushes the fluid from the after supercharger nozzle to the pre-supercharger nozzle at idle when the water system is off. I have ordered a check valve to fix this and I'll probably go back to my original plan once I get it.

Also pictured is my x-pipe since my exhaust is a fairly new setup. Sounds awesome IMO, can be heard in the video. IMF headers to 2.5 inch pipe (no cats) to the x-pipe then 2.5 all the way back to dual Magnaflow mufflers.

Great times, man, your car is impressive. I don't remember if this has been asked before, but is there any particular reason why you haven't done a front-mount? I bet you'd see some good gains, especially in conjunction with the meth.

I started off with an intercooler. I've probably tried more piping / intake setups than anyone. LOL.

I never really liked it, it was an ebay intercooler so maybe thats why. I actually made the same power and a little more tourqe without the intercooler and before I put on the water / meth.

Haven't been on a dyno since putting on the water / meth but I must be making more because my track times have gone down and my trap speeds have gone up.

Valve body sent to IPT, rebuild kit from IPT, Dragon convertor, disconnected no 4 solenoid, oil cooler, suprastick trans controller, line pressure cable as tight as it can possibly go, dex3 fluid.

I think thats it, LOL.

I'm looking into getting some cams.
