So my dyno and 1/4 mile all suck but at least I have some power to prove from all this!! This tells me my dyno reads low and my tires suck for the strip. I'm getting 6.5 seconds on the vid and that's with my tires chirping in 2nd. I figure that's a good tenth or two right there if i can get them hotter. This is ZL1 and C63 AMG territory so woohoo for only 302rwhp.

Idk how many of you have GT wings or GTC wings but holy crap is our trunk weak!! If you mount the base screws through more than 1 layer of the inside re-enforcements you're going to bend the deck lid as it gets sucked down in. So I only did the outside skin. Well that's way to weak and thin of aluminium. So I beefed it up a little!

 

Now the trunk has 3 layers. One of which in the middle is really thick metal. The other 2 are just paper thin. I didn't want to cut through all that so the new under mounts are only going to the back 2 screws because I didn't want to cut more. The old method was just aluminium blocks about 2x2. From the vid you can see major flex!

Now I have a piece of steel angle iron under the lid. Welded to that is another piece about a foot long so I can unbolt from the inside and still use the trunk. Then more angle iron welded to a 5/8" thick piece of steel then bolted to the trunk floor. I'm still not done with the drivers side and I'm going to bolt both sides together for lateral support on the inside. But over all a major difference! The car now moves vs the deck lid :)

Well it's finally time. I'm tired of fuel starve so the gas tanks going to get cut in half. I'm going to have a local shop do it for about $150. It's not only the fuel starve issue though. The main reason I want it cut is to 1. Install a side exit exhaust out the side skirt in front of the rear tires so 2. I now can do a flat bottom and proper rear diffuser.

 

1. I'm going to have to figure out if I can reinstall the fuel gauge sensor.

 

2. How loud is it going to be because I wanted to do a fuel cell but the cost just sucks. So I won't be doing dual side exhausts at 2.5" but doing a single drivers side exit at 3" because the drivers side tanks getting the chop and not the passenger.

 

I guess wish me luck and comment with any concerns or ideas we might miss.

 

 

Ok in less than 45min I unbolted the CBE from the X pipe, removed the W and Y braces, removed the crazy light carbon drive shaft, heat shields and disconnected the E brake. Moving nicely.

Ok the tank took about an hour alone. Pretty easy as its only held in by two straps and 3 hoses but the two 17mm strap bolts have zero room to remove from below which are above the subframe. I had to take two nuts and from inside the car, lock them together around the threads sticking up from underneath and then loosen them. Then below I could remove with my fingers holding the tank up with my other arm.

 

So much room! My heads spinning with all the activities we can do! So many activities!!!!

Deleted the side curtain air bags awhile ago and had a whole bundle of wires taped up. Decided to delete the center airbag module which made me dig into the the passenger side harness again. Before i knew it only one wire was actually needed for the windows last 1/2" up and down. Now its so clean.

Its begun. Time for a flat bottomed car and a rear diffusor.

 

So far the car has a front splitter that goes back about 4 feet covering where the old shield used to be. Now ive got another 2 feet about to go on with this template i made (just need matterial i wanna use). The rest of the way back should be pretty simple cutting out spots like where the exhuast flanges hang a little low and going out far past the side skirts for some side splitter action.

Now onto the rear diffusor. Im still not sure what to do but this is what i have so far. The diff cooler bracket i made to catch air under the car and force it up into the cooler has what seems to be a 15.2* up angle. A 458 i tested had a 17* up angle but ive also seen flat diffusors. Guess this is as good as its gonna get without a wind tunnel. Now on a rainy day on the highway a huge rooster tail can tell a lot about a diffusor. Im also not sure how many fins to use or if they should be straight or taper out like ive seen after the center 2 like this / | | \.

 

image.jpg1_zpscvn0cdqe.jpg

 

What i did since the car was up in the air, i ran a string from the front to the back touching points of the car. This insured the flat bottom will be flat and that the fins are parallel to the ground. So far ive made 2 fins that are 10" apart. I dont know if ill have 4, 6, or 8. These 2 are straight as a arrow.

 

Any thoughts from here????

Well heres 15.2* and 8 fins then! Centers 10", next 2 are like 5.375", and outer 4 a like 7 something. Just something i picked. All are 100% parallel with each other so we'll go full scale with alumilite and test with string i guess.
