Well I'm back from Titan! Darin informed me that my boost controller was off by 3psi! Turns out I was only running 14psi this entire time I thought I was running 17-18psi. The Haltech pressure sensor shows the base boost at 14PSI however the Greddy boost controller was indicating higher, I was told the Greddy controllers are known to be incorrect.
I made 470 RWHP at 14 psi and 631 RWHP at 25 PSI at 82 degrees and 27% humidity. Darin told me my numbers were spot on for a standard 74mm turbo. We also got the idle air control motor to work as well and the driveability is a bit better. I'm going to get him to set up my anti lag 2 step, he was telling me once thats hooked up I should be able to launch about 15psi on my drag radials and cut some 1.6 60 foot's. I need to get the speed sensor hooked up before doing that though. I'll probably hit the track tonight and Friday, I bet I'll be kicked off after the 1st run though. On the below run the boost controller was surging, it was corrected on the next pass with a little gain adjustment, you can see the wavy graph shows the boost surge.

no I meant to bring my camera but I left it home, based on the HP I should be running about 130 MPH in the 1/4 now, I plan to install a heavier spring in the wastegate which should give me another 5-7 psi, I picked up 15.5 RWHP for every PSI over 14 PSI so that averages out to about another 100 RWHP or so, I figure at 32 PSI I should be making 720 RWHP good for mid 130's in the 1/4 is my estimate, but we'll see.

Thanks, this morning I bought the new Precision Billet 7675 turbo, the former owner put 1000 miles on it and made over 813RWHP @ only 30 psi, the boost was kept down due to his stock motor, I've seen people make over 950RWHP with this turbo and it spools quicker than my old Precision 74 GTS.

Went to DD Tuning yesterday and spent some time with Darin tuning the Lexus. We filled her up with 93 octane and spent about an hour tuning the car in, Darin really did a great job cleaning the driveability and got the tune spot on with the new turbo / cams. Last night I went to the track on pump gas and got to spank down my friends 5.0 Mustang with a 383, I ran 12.4 @ 124. I was very happy with my MPH and cant wait to get the antilag, line lock, E85 set up with some new tires. I have a couple of videos I'll post up. If I could have just duplicated my 2.0 60 foot that I did last time I would have gone 11.6's on 93 Octane. My 60 foot was horrible with a 2.4 this time out, I think the big difference was the fact that my drag radials are below the wear bars now, where the last time they were new.

Here is a video of my 13 year old kid and I running the Lexus last night, you can see in 1st and 2nd gear the camera shakes from all of the wheel hop / spinning.

12.4 @ 124 mph with a horrible 2.4 60 foot. The last time out when my Nitto Drag Radials were new I was able to cut a 2.0 60 foot, had I accomplished that 60 I would have gone 11.6 on that run. My tires are bald now, need new ones. I plan on making a big jump up soon, race gas + antilag + good tires should get me in the 140's.
