[awd-drifter]

amazing build...I'm sure one day, we'd like to do some rally build like this too. I always liked how N/A cars felt right off the bat. I'd love to do at least one beginner's rally event sooner or later. let us know how it's going because this is an amazing build! :D

[LingLing]

This is awesome! Like awd-drifter I want to do a rally event as well. This definitely gives me a lot of inspiration to maybe make something like this happen in a few years. Keep us updated!

[A//// Guy]

This is sweeet. Woo Hyundai!

[Super Bleeder!!]

Very nice Paul. Have you guys ever considered putting an Alpine on this thing?

From the OP: "..within the rules of the G2 class (2WD, N/A, under 3050cc)."


Awesome project thread, looking forward to more.

This is a great build, and the final product is awesome. ;)

Thanks for all your kind words, guys... it's been quite a journey so far (with a lot of learning) and it's FAR from over!

Badass man. Have you become pretty familiar with Megasquirt then?

Yea, I've done quite a few systems and mods over the years, been running my 1g on it for the past 4 years and I really like it. It's got pro's and con's...of course. The biggest pro is how active the open source community is. Because of that, innovation is always happening, unlike other closed systems. Biggest con is it needs more inputs for telemetry.

This is awesome. I love reading rally builds. Please keep updating! I am strongly considering rally after my Chumpcar forays are over.

I have a few questions:

How the heck did you remove the windshield without horribly messing it up? Or maybe you did mess it up...

Is there performance limitation to Group 2? I haven't spent much time reading RallyAmerica rules.

Hah! That windshield is no longer with us.... The can be removed with a lot of patients, but usually if the window weld is past a few years old, I've found it's very hard to successfully cut though.

G2 is ranked on a engine displacement to minimum weight slider. The bigger your engine is, the more your car must weigh.

This is the formula:

Very nice Paul. Have you guys ever considered putting an Alpine on this thing?

Thanks! And yes we have... and also discussed prototyping an AWD swap with bits from a SantaFe... but for now, there is still lots of power to unlock in this engine! You'll see as it progresses :)

Very cool thread and it was fun to read through and see the progress the car has been through. Definitely a project thread I will be checking back on regularly!

[1QUICK4]

Very Nice! If you guys need any discount factory parts don't be afraid to hit me up.

For many years I have wanted to do an old AWD Hyundai Scoupe for rally.

It was awesome watching this car in action at the Nemadji rallies. Too bad the engine had to let go on the last one. Just glad it wasn't an off-road excursion that ended it for you.

Good luck this year! I may or may not be able to make it out to a few of the events this year. I won't be running safety sweep, I believe Denny will be this year. But I'm sure Frank and Carlton will be right behind him with their big rigs ready to lend a hand when needed.

Keep us up to date on this thing!!

Probably time for another update… Still back logging events from 2010, but want to proceed linearly to help me with my thought process.
2010 was very much a teething year as we tried to get the bugs worked out of the new chassis and start building speed. I’m going to focus primarily on the build aspect rather than our racing program, as the car is still very much a work in progress as we use the data collected on stage to make modifications.


Here’s what we learned in 2010:


The car performance was mixed on stage… overall very balanced, but needs refinement
Cornering and grip was terrific for a 2wd platform, partially thanks to the heavier engine in the nose.
Braking needs to be switched to a manual system -- it is very much over boosted, and has an all or nothing feel. Work as begun on fabbing a new manual system.
We had a massive issue with spark dwell that greatly affected performance in our first two rallies. Once that was fixed straight line speed was dramatically improved.
Solid motor mounts = really bad idea in rally
Engine has good low end torque, but needs more power above 5000 RPM
Need to fab coolers for *.*
We need thicker gear oil
Engine fires suck.
Apparently it’s not a ‘race car’ unless we rice out the exterior…
Could stand to lose a few more lbs (both car and occupants)
Needs dyno time… I developed the spark map from the seat of my pants; it’s good but not great.

So yea, 2010… Mid way though our intended season, disaster struck on stage.


About 2/3 the way though SS1 at NT3, the engine suddenly changed pitch, and the car started shaking. We at first suspected we lost a coil, since they were acting up recently and decided to press on to the finish. About 1 mile later, very bad things started to happen:


I’ll let the pictures tell the story:

OMG TIME TO RALLY, NOTING BAD WILL EVAR HAPPN111

I think this might be more than mighty putty and a 45 minute service can handle...

So yea, this is what running at max race load with a spun bearing can do! (in case you were ever wondering). Basically the entire bottom end grenaded and in the process started the engine on fire...

Mess.... Mess everywhere!



So, things being what they were, and other project cars screaming for attention, we decided to shelve our rally plans for the time being and regroup over winter.


Stay tuned for the 2011 rebirth!
