Going back to the dyno tomorrow. The wastegate was only being held by one stud during the pull. There should be more power to be made at the same boost level. More yet to come.

What is done to the head to rev to 7500 in your mind safely? Assume all crower up top?

I was reving to 7500 on stock valvetrain and never had a problem but I got a sweet deal on Supertech springs and retainers so I went ahead a bought them plus I'm going to a bigger turbo near the end of the year and will need more power band (8K or so) to have more power band for bigger turbo coming soon. But the stock valve train can be modified to take it as well with out any problems. I've over reved to 10K on my stock valvetrain setup and never hurt the head.

Awesome numbers, congratulations!

I'm curious as to what disc, pressure plate, and clutch slave cylinder you use.

[480sx]

Wow, 10g's on the stock valve train.. Thats pretty absurd dude, your nuts for trying that lol. Was that an accident or what??

What was your rational when chosing to use a stock cam on the intake side and a big exhaust cam? Never heard of anyone doing that, just curious why you chose to go that rout.

Throw some pics up of your car/engine bay if you get a chance, thad be nice to see.

Sweet numbers, cars gotta be a blast to drive.

[duncan351]

The 10G's was an accident about 4yrs ago. Was speed shifting and missed 4th. Instead, went back into 2nd. As for the cam combo, its widely known that the BC stg3 cams either work for great for some people or they are horrible. Well, I was one that they didn't work for. I triple checked my timing marks, then used my adjustable cam sprokets adjusting the intake and exhaust in every different cam setting (Took hrs...) Still no success. So I installed the hottest S13 exhaust cam I had. Success!!!!

Doing anything to the crank? lightened and balanced? or have you already had crank work done?

VIDEO?

[duncan351]

Will have videos soon hopefully. The crank was internally and externally balanced but that's it. The clutch is my personal clutch with an old Clutch master pressure plate I reworked. The car on the street is sooo fun. 3rd gear is like my 2nd gear. When boost comes on, the car just kicks sideways and blows the tires. 4th not as bad as 3rd but I also have another 150lbs or so in the trunk with at this point is helping me.

Here is the latest dyno chart:

That TQ curve is vicious, great work once again.

[Florida240sx]

Very nice. We need video. And 1/4mile time
