2.6" Pulley, 60's, dual pass, cobra HE, trans mounts, motor mounts, intake, pacesetter headers, full 3" exhaust catless... and a custom tune for race gas 109 octane (though it was a mild race gas tune)

Fixed it for ya. I was only runnin 19-20 degrees of timing on that tune. I was also running 11.4-11.8 AFR which is richer than when I really had it tuned up, which was 25.5 degrees of timing and 11.9-12.2 AFR, that **** was retarded fast on that setup.

11.8 is just fine, as long as it below 12 its fine. Specially with less boost, and cooler air. Plus pistons that will laugh at the puny amount of power I'll be putting out.

Nice. My mods below reflect the current rebuild, the motor is being resleeved currently. I got a few guys doing custom turbos near me and depending on the numbers I might give that a go next summer.

What are your plans for the motor?

no dude, korn sucks.

We can't afford concerts anyway. That show had some good bands... but i didn't want to hear some accoustic bull **** from korn and amy lee... but evanescence would have been cool to see.

If you find a part that is actually a set of 2.0L LSJ cam blanks, please let us all know where. I haven't found anyone who is actually selling them.

Yeah, its looking more and more like I'll have to just do a stock regrind.

On a lighter note, the Driveshaft shop, just agreed to sponsor axles for my car

Cam,

Do any shops around here do dyno tuning for our cars? I was gonna go with steve but he won't up my limiter to 7500 so i need another option and would actually prefer a dyno tune.

Good for Steve. He's keeping you from ******* up your motor. #1 Your motor will be doing nothing but screaming at 7500 rpm. #2 Stock valve springs are rated to like 7150-7200 rpm, but it lowers as you continuously rev the **** out of it. #3 I reved my car 7000-7100 rpm, and when I opened the motor there were tell tail signs that I was floating the valves, and that was at only 7000-7100 rpm. Get new valve springs, THEN rev the **** out of it, but before that, its not safe to rev that high, nor is there a reason to rev that high without aftermarket cams.

Oh, well since this is MY update thread, I might as well update! Today, BOTH The Driveshaft Shop, AND Crane cams agreed to sponsor parts/services. Driveshaft shop is sponsoring a set of axles, and Crane cams is sponsoring a regrind of my stock cams!

L61 rods failed at 287 hp. LSJ rods are A LOT more beefy. They say they're good to like 400-450 hp, but I ain't takin a chance.

What do you tell people they get for sponsoring you? I'm just wondering as there is a local race shop I would like to sponsor and maybe they could help me out as well.

Oh and I never did get an answer about what your plans for the motor were?

I never said anything about stock valvesprings. As for not making any power over 7000rpm. I'm back on the stock pulley and going to 7500 will increase boost and should produce max hp at redline.

Na, cam profile won't support power up that high. Have you seen the stock cam profile!?!? Its pathetic! More mild than the L61 cams!!! 189 duration @ .050, ~.380 lift, 113 LSA. Simply pathetic.
