Well.....It made 470 at 14lbs of boost. when I upped the boost to 23-25 on the same engine it felt a lot stronger. The old engine was about 9.2-1 compression ratio. Now the CR is 8.5-1. So it should make a little less HP at the same psi. I can also turn the boost up more with the built engine. Long story short who knows but I'm kind of targeting 650whp.

I took it to the 1/4 mile track the other day and ran an 11.29 @ 130mph which makes my SC one of the faster manual SC around. I was pleased with the times and I had a good time. I also road race the car in the local super lap. I won my class in 2009 (class A) and this year I should finish in the top two (Unlimited class C).


Also I have worked many of the drive-ability kinks that I was having earlier with the car. It drives very nice (still not stock) and is very suited to be a DD if I wanted, I also use the car if I have to travel without the family which is about once or twice a month. I might add that I have been DD'ing the car since the new engine. I also raced yesterday where I got 2nd. I lost to an ariel atom (I need to get out of the unlimited class)  


I've also been busy working on my car this past month or two. I installed some gauges and I decided to put them in the glove box so if I'm just getting groceries or cruising I'm not attracting unwanted attention. Sorry just cell phone pics


The main thing I did is install a Canton Accusump system in my car along with the 6" filter with no filter bypass. The accusump pre-lubes your system so that you never dry start your engine even if the engine has not been started in a while. And also works like a drysump because it stores oil in the blue cylinder and in the case of oil pressure drop in your engine it will supply pressurized oil to your systemThe install went pretty smooth but I already had a cooler so I just ran -10 from the accusump to the -10 cooler lines. I'm a Canton dealer so if you have any questions just email me. 


I made some simple mounts for the brackets to alow for a cleaner install.



Here I just ran a -10 bulkhead 90 through the trunk floor. I also mounted an inline filter because my oil cooler is pre-filtered oil. I forgot to get any pics of how I ran the line under the car and the filter but it is pretty strait forward.



This is where I decided to tap into my oil but I'm making a dedicated track car (93 SC300)in the near future and I might just tap it strait into the block but I'll cross that bridge when I get there.
