    ITB's and crankcase ventilation

    I'm in the middle of a decision making process. I thought I was going to pull the trigger on ITB's for my LS1. Previously I had a double catch can planned for my standard intake/throttle body setup....which won't work well for the ITB's without a vacuum source. I'm not that familiar with...

    Tensioner location/config

    As I understand it, in chain drive system a tensioner should be located on the slack side and a pulling configuration is preferred. Is there a optimal location and config for Serpentine belts? I almost always see the tensioner directly after the crankshaft or close to it and can't see any...

    Bracket requirements for fuel/Brake lines? - CA

    I recently saw a thread mentioning spacing of brackets for mounting brake lines (like must be every 20"). Does anybody know if there are such requirements in CA for mounting fuel or brake lines that the BARR will look at? Any other odd things like this to be aware of? What's everyone using to...

    Aero and radiators

    I haven't cut the hole for my radiator duct yet and wondering the correct sizing. I know the opening should be smaller and open up toward the size of the radiator to slow down the air and create a high pressure area prior to entering radiator (more info see Carroll Smith). However since the...

    Venting High Pressure Surge? & will in-tank leak under LP pressure?

    I have a pretty typical setup planned. Front Mounted fuel cell with Rollover/vent feeding the surge tank in rear with a low pressure pump. My question is has anyone seen issues by not venting the high pressure surge tank loop (venting the surge tank). I assume pressure will be relieved by...

    RCR/SLC adapter plate G96.01

    I think there's a couple people who've used the RCR/SLC adapter kit for the g96.01 and LS. All I received was the adapter plate and flywheel. I know others have at least gotten bolts but I'm not sure about instructions. I've got a donor flexplate from an 04 C5, but it doesn't seem to align...

    Fuel Pressure explained

    Nothing ground breaking here but this short article put a couple concepts together for me especially concerning Fuel pressure and injectors on forced induction systems and return vs returnless so I thought I'd share it... Fuel Pressure Explained

    Manual steering rack question

    Crossing my fingers that I've measured everything correctly for the steering rack...however there were three options for the steering ratio on this custom rack. 3.8 turns lock to lock (slowest), 3 1/8 turns lock to lock, and 2.7 turns lock to lock (fastest). I choose the fastest (1.8...

    Shift cable grommet for bulkhead

    Did a little searching around and not finding anything specific or of great quality but I think I've seen some on this site. Do you guys have any suggestions/solutions for grommets for shift cables through the bulkhead?

    PTV clearance on engine rebuild

    So based on my calculations I thought I would be close to .09 clearance with my current setup. I installed .04 cometic gaskets for improved quench and I've tested two cylinders and got about .06 PTV clearance with checker springs on the intake side. I've heard that due to using weaker check...

    LS and Transaxle mating guide?

    I thought rebuilding the LS would be a snap, but there's always little things that slow you down (when you're not a pro). I'm getting close to mating my G96 transaxle, but not having done it before, I don't have a lot of confidence that it will be a breeze. I realize there's tons of...

    Superlite Fiberglass Voids

    Basically was able to just push through most of these voids with my fingers. How typical would you say this is of Superlites body work?

    Airbox/Intake design

    Has anybody ran across good information on airbox and intake pipe design. I know a lot of the SLC take air straight from the tail area instead of the side scoops but I plan on pulling air from the b pillar scoops of the apex. Reading on Bernoulli's equation and venturi's but not sure I fully...

    Rigi Grip for stainless coolant tubing

    Thinking about using Rigi Grip for my coolant tubing which will be exposed in the tunnel under the car. Was thinking this would help with heat transfer and surprisingly the 1.5" is slightly thicker and 15% cheaper than plain stainless. good idea? bad? 1.5" x .035 smooth stainless 1.5" x...

    Body work suggestions

    Can someone direct me to a thread or two on the suggested path to body work on these gel coated fiberglass bodies? I'm unfortunately in the situation where I'm now building my car a couple miles from my house. This just means I can't pop into the garage and get things done and is going to slow...

    Open Builds Plasma CNC

    I'm considering building an Open Builds Ox based Plasma CNC table. I think it will help fabricate a bunch of the parts I'm going to need in my APEX build. Problem is every minute and $ spent building IT is not spent on the car...plus not sure how much use it will get after. I'd be using a...

    ABS and traction control on Apex

    I am entertaining the idea of adding both ABS and traction control to my Apex build. Would like your opinions on having (OR not having as many of you prefer) them on your cars AND if you have information on incorporating the C5 ABS as a standalone. My car will be about 75% street use so I think...

    Rocker Panel straightness on Donor Eclipse

    Can someone tell me how important the straightness of the rocker panel on the donor car is. Are little dents fine on the lip underneath? Most of these cars look like they drove off curbs etc. This fine? Are dents like this on the lip okay? <a...
