Don't get too excited, this is somewhere between rocket science and "hold my beer, this'll be cool".

A very ambitious build, Rohar! A fun thread to follow.

I have limited fabrication skills, so I'm doing a Renegade conversion with an LS1. Question: What do you use to cut the sheet metal for the openings? I was hoping to use a reciprocating saw with a carbide blade, and then do some finish grinding to neaten it up. Are you doing something similar?

Also, what size rear tires do you have? I want to fit 225/50-15s on 15x7 ATS wheels. Tonight's project was rolling the lip and pulling the fender out about 1/2" on the driver's side.

Thanks!

Cheep jig saw from ACE (you know, the helpful place!) and a couple of bimetal blades. There's some tricky spots in there so I cut the deck on the saw down to a sliver so it wouldn't be in the way in some places. 1" hole saw for the corners, I wanted pretty radiuses. It goes pretty quick, but WEAR EYE PROTECTION. You're gonna bust a couple of blades and they'd suck if they stuck you in the eye.

I've got some interesting ideas on how to treat the cut edges that should abate flex cracking and make things a bit prettier. Stay tuned.

Tires are currently 225/45/17s on Enkeis. I'm not sure I'm gonna stick with the tires. They look a little too low profile for me.

Doubled horizontally (as compared to a single 1" square tube), the deflection is roughly cut in half.

Doubled vertically, deflection in this case would be reduced by a factor of 4.

There will be a lot of different forces at work. My concern is the basic vertical load. A 500 lb static load may result in deflection of 0.1" and a max stress in the range of 10ksi. A shock load (speed bump, railroad tracks, pot hole, etc.) could be 5 times that resulting in stresses higher than the material (and welds) can handle, especially when repeated.

Your design may be perfectly fine, I can only comment based on the picture and information given.


If it were possible to go vertical, trust me I would have. Because of where everything ends up (half shafts, exhaust etc) there just isn't room for bigger steel.

Once the engine/tranny are back together I'll bolt it all up with the bigger assemblies and reassess. Thanks for the input though, that's a big part of why we post these things in the community!

Thanks! I'm a ways off from cutting...I'm waiting on Renegade's cooling package, and there might be a template with it for the cooling exit holes.

Yeah, I know what you mean about sidewalls. These cars call out for a substantial sidewall. But the ones I have now are terrible....195s with a 65 aspect ratio. They look like big glazed donuts!

As promised, trigger solution:

(IMG:http://www.914world.com/bbs2/uploads_offsite/i910.photobucket.com-9685-1339793880.1.jpg)

It's dual mass so it's heavy as hell and doesn't leave much option for lightening it. On the up side, I can run cheap solid center clutches and there's one less thing to fabricate.

There's even a mount point in the bellhousing for the hall sensor. The VAG parts bin is awesome.

Ok, I've been neglecting the 914. I'm a bad man and I should feel bad. I can't help myself, the 944 is like 2 weeks away from being track ready so it's taking up the lion's share of my time. That said, I did procure these for the teener today. $275 for the pair, never used, only test fit. With ajustable sliders:

So I've got this groupie that won't leave me alone. He's kindof a nice guy, but he pushes my ass into productivity. Honestly, some mornings, it seems more than I can take. He's the reason the '44 is up and ripping. I love him for that and hate him all at the same time.

He stole my beutiful seats and stuck them in the '44. Meh, such is life.

After many conversations in the shop, most of which sounded a lot like "you can't put that 6 in that car when there's an 8 sitting right over there" things got exciting this week. The six is officially on the scrap heap and I'll never speak of it again. The yoke is being modified for the 3.6. Given what that silly little '44 did this weekend, what happens from here will probably be epic on many levels. Here's to the next messed up chapter!

/still kinda want my damned seats back :|

Not yet. Obligatory fuzzy picture for the day, progress however small:

Yeah yeah yeah. If it helps, I'm moving much faster than normal lately. Damned driver works evenings so he shows up at some god awefull hour in the morning to give me the to do list. Spring's gonna be a riot. One race care in pocket and another on the way.

Andy, sorry about stealing your camera. I couldn't help myself.

Woot! I've just been given an offer on the '44. Sometimes things just come together. Gonna run through some numbers, but it looks good. Budget for the teener!

We're all going to die...

I know, terrible question to ask on your wedding day, but do you mind if I put this in through the rear?

(IMG:http://www.914world.com/bbs2/uploads_offsite/i910.photobucket.com-9685-1350077038.1.jpg)

Oh, and yes, there's a lot more metal to add to that yoke, test fit.

Tough end to the day. Somehow I'm an inch off on one of my dimensions. Car goes back up in the air and the engine comes out one more time. Then I think it's time for a shopping spree.

I'm having one of those evenings. Go out to the shop, lay things out, get to work for all of 30 minutes then come back in to think as I've run out of steam. You're not helping there buddy!

Oh, and it's all those years of telling girls it's only 6 inches, it's warped my perspective as I'm starting to believe it. (IMG:style_emoticons/default/smile.gif)
