Went to the track today. Horrible experience all around. Took me an hour to get through the damn gate it was so busy. Made 1 pass, 12.2 something. Had added some timing. Was pinging a bit so I let off a little around half track. Was not running right when I parked it. Missing a bit. Decided...

I'm very likely going to a quarter track tomorrow. I've added some timing, hope she dosent blow.:eek: With all the water / meth I'm injecting it shouldn't be a problem. Been driving on the street with the extra timing and so far no sign of knock but its about impossible to really get on it off...

What would you suggest for my daily driver? Care to guess at gains? I think its safe to assume I'm making near 400rwhp now. I made 350 on the dyno way back when I was trapping at 108mph. Now I'm trapping at 115mph. 115mph and 3600lbs comes out to 394.62rwhp using this calculator...

No, I spun quite a bit and when it finally caught it hit hard. The 4.27 WAS NOT an improvement! It was slower. For whatever reason the 3.92 works better with my setup. KC

I don't know if I had mentioned over here but I did have an SC300 4.27 diff with the Torsen installed. At the track a few weeks back I somehow broke it, was making a ton of noise. I took it all apart and found nothing wrong with it.:confused: Took the Torsen and put it back into my 3.92 diff...

spf_lexus - not looking to change head units until I blow this one up. Maybe one day. turbotalon1g - soft rev limit is set to 6900rpm and the hard limit is set to 7100rpm. The transmission controller is what determines where it shifts at though. Trying to keep it in the 6800-6900rpm range. I...

Problem is that I can't simply bump up the pressure. Keep in mind I'm using a V-9 F-trim, one of the smallest Vortech makes. I already have the smallest pulley I could find on it. I'd need to change head units. KC

Thanks guys. Problem is I've been chasing 11's for awhile now....:mad: LexStarr - in my signiture. Vortech blowing about 12psi. KC

Thanks. I kept looking for him in the rear view but couldn't find him.:p I need to put the thing on a dyno to see if there is anymore "safe" power. I really want 11's. I should be able to do it with 115mph trap.... KC

Best run of the day was 12.069 but this is the only one I got on video. http://www.youtube.com/watch?v=S5kSz6s0xog&feature=feedlik Still trying to get 11's. Still running a bit rich with the Adaptronic but getting close. Not dyno tuned. KC

Also (sorry to double post) from what i've seen, fuel cut is a very safe way to cut power. When I still had the factory ECU / Maftpro combo and before I had my transmission controller I used to hit the rev limit fuel cut all the time on WOT 1st to 2nd gear shifts. I could probably find a few...

You can't run lean if there is no combustion event and there won't be a combustion event if no fuel is injected. I think it is more dangerous to spray fuel into a combustion chamber that is heating up due to retarded timing / cut ignition / high EGT's than sparking in a chamber that has no...

Thanks Steve. I'm still waiting for you to run your car! Although I'd like to be the one to break into the 11's, LOL. KC

So I am still attempting to break the 12 second barrier with my car LOL. For anyone following along I've managed a best of 12.04. I have run a few times (1/8 mile) since putting in an Adaptronic ECU but have had a few issues, I think I finally have it all sorted out and would like to give...

I think there are a few things considered fact about the 1uz that are only partially true. Anytime I've had mine on the dyno the power was steady going up all the way to redline, about 6400rpm or so. Now that I have the Adaptronic I should put it on the dyno again to if going to 7000rpm is...

Injured really, not broken. Ran the 1/8 last night and was having traction and technical issues all night. On my last run I spun the tires through most of 1st gear and my rear end was growling afterwards. Took it apart today and found nothing obviously wrong with it. Took out the Torsen...

Not sure that this info will do anyone any good at all but I have learned a few things in the process of getting a speed signal from each wheel to my Adaptronic e420c ECU so that I can use traction control and launch control and I thought I would share. Note that this info is based on my 95...

The time slip for that run mentioned above can be seen here BTW - http://www.dragtimes.com/Lexus-SC400-Timeslip-16866.html KC

Ya its definately fast out of the hole. Despite having a Vortech which people insist only make top end power. I know of 1 or 2 SC400's/4.0 Soarers that are faster than mine in the 1/4 mile but I'm pretty sure that I hold the top 60ft times.:p Also, my best 1/8 time is actually a 7.702 @...

http://www.wallaceracing.com/0-60_equation.php If you put in my past best 1/8 numbers (7.703 @ 88 something) it comes out to 3.58 seconds. KC
