Well, I was finally able to get on the rollers to see what gains a custom cam, full exhaust and e85 can do. Prior to this I only had a Vararam and axle back on it and put down average numbers (360whp/355wtq). I dyno'd 2 days ago at the same place and was very happy with my results:

422whp/405wtq

Mods are as follows:
- Custom grind cam - 238/240 - .600" / .600" - 112 LSA + 2
- LG Super Pro longtubes and X-pipe
- GHL Bullets
- Vararam
- e85 with 42lb. green tops

I haven't been emailed the dyno graph quite yet but I'll do an overlay from my stock run to see where the big gains are as I know my midrange really picked up.

I took this video from my phone, she certainly doesn't lack in the noise department:

Very nice gains! Stock intake and Throttle body?

JohnnyT13

Stock LS6 intake mani, yes. The t/b is very lightly ported but OEM 78mm.

Congrats! Very nice looking car. I had ported LS6s (old MTI) on my heads/cam car w/ a LG cam (seems similar to yours) and a fast intake and it did just 441 rwhp. With your car being so light, I'm sure it's a pretty fast car.

Thank you, sir. I'm still debating how much farther I want to go. H/I is the obvious route here but it'll cost me $3k+ to gain what, 30-40hp? Not sure that's worth it, and clutch will need to be replaced as well. I'll keep enjoying it for now though!

Well, I FINALLY got my damn dyno graph. Here she is:



Of course I'm happy with the peak #'s compared to my stock dyno (360whp/355wtq), but I was more concerned with WHERE I picked up the power, so I went ahead and graphed the comparison. To me, it's MUCH more interesting:



All in all, I picked up a good 15-60whp and 20-50wtq. within the powerband and the meat of the power is right where I wanted it with the cam.

Nice gains bro, gotta love the c5 z06!

I want a c6z but seeing your c5z makes me realize just how sexy a c5z is.

A lot cheaper too with just about the same perfomance after a couple mods...as long as you don't try to convert the c5 headlights over to c6 style, which is the ugliest and worst mod anyone could do to a vette!

JohnnyT13

Thanks!

You really can't go wrong with either. I can't afford one and I still haven't warmed up to the new styling. You could always do the best of both - LS7 in a C5Z!

Couldn't agree more - destroys the bodyline and becomes the focal point of the car. To each their own, but it's hideous to me.

Great numbers, Johnny! The massive gain in torque alone was well worth it...
