The $2008 Grassroots challenge build-up thread

I agree about the Megasquirt. It is what I am setting up now. It is a great cheap standalone.

Damn, you guys got a DEAL on that car, especially with all that it came with, the rims/tires combo probably cost just as much as you guys bought the car for, or even more! The car looks and sound badass, what kind of exhaust is that? Sorry if I didn't catch it if you guys already mentioned it. GL!

pretty cool project! time to strip that bitch down Lol, maybe strip the doors of all reinforcement since you will have the rollcage? oo lots of other stuff too lol
foglights alll that

it's just an open BIC DDP..we don't plan on leaving it like that.

tlo86...why the fogs, do you want them? :P

[themadhatter]

looks like you guys are starting to make progress what are you going to do about the targa? weld it shut?

nah just another thing i would deem as extra weight

targa stays, just cuz it's gangsta getting the car sideways without a roof. we're hoping we can brace the chassis enough to be able to keep the targa a removable option.

First off, sorry for the pic quality, I forgot my camera so my phone had to do the dirty work today.

This afternoon I stopped by the shop where Edwin was taking care of some small issues. A missing rear wheel stud was replaced, and the tire was patched from the inside where a screw had punctured it. The car has had some sort of popping issue issue when you get on it real quick. Sounds almost like hitting the rev limiter, but at lower RPMs. We were thinking that maybe it has something to do with running rich and having the open downpipe, so we are hearing a noise that would normally be muffled? Does that sound right to anyone?

Anyways, I checked the ignition timing and it was almost 3 degrees off. I don't know how much of a difference 3 degrees makes, but I adjusted it back to stock specifications, and the popping seems to have moved higher up the rpm band. We have yet to perform a simple tune up, (plugs, fluids, etc.) So we'll see what that does to help.

So besides what was done, it was taken out for a quick test drive. I guess it was overdue for a problem, so the heater hose decided to blow off. It wasn't so much the hoses fault, the problem was the fitting on the actuator broke:



Soo yeah. We wanted to bypass the heater anyways, because we are removing the whole HVAC system. Although this isn't really a bypass, this was our quick fix solution



Should hold for a while.

After we put the fitting on, E attempted to start the car but it wouldn't start. We deduced that an ignition component must have gotten soaked, so a plug wire was pulled, and our problem was obvious. Although it is cleaned in this pic, the whole spark plug area was swimming in coolant



So a lot of time was spent cleaning the engine bay and components





Well, that's all I got, stay tuned!

time to strip that bitch down Lol, maybe strip the doors of all reinforcement since you will have the rollcage?

Definitely gonna be more strippage goin on! We're still undecided about the door panels/reinforcements. Two reasons for that, one is that the weight of the panels + reinforcements might still be lighter than a nascar style door cage or even just a cross-brace. The cage is gonna have to be made out of heavier steel because we don't have room in the budget for Chrome-moly. Second reason is that the door panels look pretty .

That heater valve is a common problem, you're better off without it. Plugging the system so that you don't have any HVAC at at is actually pretty trivial, and will drop a fair bit of weight too.
