I figured I finally needed to get the Nerd Rods TriFive car posted up. We plan on doing lots of touring and autocross in this little guy and giving lots of rides. Big power on the cheap and lots of tire on the ground. With luck we'll also get to use this car to make some instructional videos for guys looking at their own DIY frame.

Stripped off the trim the cut into the paint to see what was under it and its the awesome Rust Defender we were planning on spraying on the car anyway so not just some smoothing out bodywork. So we steam cleaned the bottom and bead linered the bottom.

We had a customer asking some questions about his chassis so we tossed our body onto this frame real fast to show him. Now I just need to get onto our frame.





I'll update this page as we get more done and I'll create an index on this first post for everyone else who comes along.

Later

I'm curious, why run rear mount turbos with all the room in this car?

Weight, Balance, Price

1) Weighs less
You don't end up with the humgunous headers under the hood with the turbos out in-front of it. You don't need mufflers and you just run the OEM cast iron headers.

2) Chassis balance
By getting all that weight that would be the turbos, headers, intercoolers and piping back in between the wheels instead of out in front you you'll reduce the amount of inertial momentum of the car and lower the CG of the car but will help largely with handling.

3) Price
No elaborate custom headers, no high flow mufflers, no real need to spend money on ported heads or really exotic intakes. All the things you would normally need to spend lots of money on to make that kind of power you get to save. HP to Dollar its hard to see any other combination that will put you into the 600-700 HP range for the same money and still give you room to grow later on.

Bang for the buck its what I really like to do. I would even run a 5.3L but I already had the 6.0L from the PT-57 project so I'm running with it.

Well you can mount them up front with oem cast manifolds. We have such a setup on a coworkers 57. I would say then you have less overall weight from not having charge piping running from the back of the car and you save weight from no oil scavenge pump.

The weight would be shifted to the rear but a pair of smaller turbos with v-band housings, wastegates, everything comes in at less than 50lbs.

You would save money on mufflers if you don't plan to use them but everything else is a wash. (well, more money on cold side piping with rear mount). Can use stock manifolds with engine bay mounted turbos and both can be used with stock heads and intake manifolds.

If that's what you prefer than by all means do what you like. From a functional standpoint I like close to zero perceptible lag which I've yet to experience with any rear mount setups.

Bed liner undercarriage looks nice btw. Seeing it on more and more cars and it's starting to grow on me.
