Supercharged LS1 Cerb runs at last!!
Discussion
Finally managed to upload a couple of vid's showing the motor running. Should have posted this up last week but had a nightmare with the exhaust, it warped while I was welding it so didn't fit well enough.
Anyway.... we just had to press the button.

First start up
So after welding in a couple of flex tubes the exhaust fits nicely and removes the weight hanging off the manifolds. Just need to fab up the exhaust tails now. Click on the link, enjoy
Listen to that blower
Here's the final exhaust system, I've copied a Chim system with the silencers under the prop shaft, the system is twin 3" with a balance pipe under the T56 6 speed gearbox.
Still loads to do before it turns a wheel, got to rebuild the diff and fit the tuscan pedal box, but its great to finally get her running.

Very nice.Does the bonnet close properly?.Or will it need a bulge?.Thanks for the comments boys,
I recon I'm going to change my sign on name, when I first joined I was one of only a few who would take a spanner to their own car, now there's loads of like minded people out there
Supercharger fits no prob under the original bonnet, the sump is 10mm below the bottom chassis rail.
IIRC I paid £3500 for the supercharger kit, ex demo kit, 630bhp is what I've heard for mine at 12psi with a mild cam, std everything else. Its at 6psi at the moment, hoping to see the magic 500bhp with the option to go to 9psi if I don't. Wouldn't mind camming it when I fit my LS7 clutch I've got kicking around but we'll see what its like first.

, bash plate is 2 x original spacers plus a couple of washers low, although with the flex tubes fitted the silencers will sit a bit higher now so I'll probably adjust it once the diff and prop are back in. I wanted a minimum of 100mm ground clearance, as per our Skyline. I'm more worried about hitting the carbon front splitter than knocking the exhaust 
that would hurt.....I think I'd cry.
Its sitting 150mm front and 160mm rear measured to the corners of the out riggers at the moment, does that sound about right??

I've always understood the correct ride height from the outriggers should be in the order of 135mm, but having said that I've seen a range of quite significant variations on that number posted here over the years. I wouldn't worry about what's 'correct', if it looks right and drives right for what you're doing with it then that's all that matters.
ETA: The outriggers are only a few mm higher than the bottom chassis rail IIRC. From the pics it looks like your exhaust / bracing plate is hanging about 40mm below the chassis rail, which suggests if you want 100mm clearance, your ride height measured at the outriggers should be 140-150ish.

Look forward to seeing it out of the workshop and on the road. could be no.2 in the power league with that supercharger. I was only expecting book value from mine of 430hp 424lbs/ft torque but turned out to be much more when it was on the dyno. I hope you get a good surprise and when you're driving it you will love it.
BTW what tyres have you got there

I love superchargers, looking forward to seeing what numbers it makes. Are you and Brummmie going to see who can get the most hp? his normally aspirated but large capacity and well tuned, and yours relatively std spec but forced induction? that would be cool to see the comparison on the graphs and in the real world

I assume you are offering a free blast on the rollers? Brummmie said:

I assume you are offering a free blast on the rollers? Yes, i'll take you up on it.
