Justin Reed Racing DF Goblin


I like anything that goes fast
I've been bad about not updating the info on my build along the way, but that's gonna stop now. My most recent rebuild this year involved basically rebuilding the entire car minus the front suspension. That means a new engine, transmission teardown inspection, wilwood pedal box, surge tank fuel system, 2 stage scavenge ARE dry sump oil system, updated DF rear control arms and spindles, new DF direct connect shifter, and added oil temp and fuel level gauges. Attempting all this at one time was a bit overwhelming and took a lot longer than i would have liked to complete. Technically the dry sump system isnt installed yet, but all the parts are there. Just need a custom valve cover to finish it up. With the wet sump still installed and everything else complete, it made its first successful break in on the dyno. New 2.1 engine made 607whp/517wtq at 31 psi while still on my old small id1000cc injectors. Below is the updated build list for the car as of this year.

That looks like an awesome build! I always talk about your car, the "585 HP" car and now I will have to update my canned speech. That's very impressive.

Also glad to see you back on the forum with updates. Make sure to get videos of your runs and post them. I'm subscribed.

Only video i have is the dyno video i already posted on facebook. Ive yet to drive the car with the new setup. We took it straight off the dyno and put it on the trailer in the rain. It hasnt dried up enough to take it for a rip yet. Very soon tho!!

I'm ready to buy one if someone knows how to get in touch with them. I haven't gotten any responses from them through their Facebook or email address.

Ecotec meet was a success, 450 miles of mountain thrashing. Disappointed there weren’t more goblins tho. I passed Joel by circumstance on the dragon and we got a chance to meet. Other than that, zero! Hopefully more of y’all will show up at next years event!

Its fine for low power or straight line traction. If you like donuts, forget about it lol itll still one wheel peel trying a donut. Also for high speed tracking, the car is kind of unpredictable on corner exit with some wheel spin. Im looking for a quaife to replace it
Really great information there! You saved me a lot of headaches. I just ordered the quaife.

Couple of questions about the rear sway bar... I am currently not running any sway bars - front or rear. I would have figured the use of the sway bar would have upset the suspension balance with the Goblin being so light - especially without a sway bar on the front.
Please educate...

1. Have you run without a sway bar?
2. Could you tell us why you chose to use the SS sway bar in the rear and the advantages of using it?
3. Have you tried the smaller non-SS sway bar?
4. Do you have plans for a front sway bar in the future?

I appreciate your input and real world experience...!!! Thanks!

Rear/mid-engine cars respond differently to swaybar applications than front engine cars do. For them, with a larger percentage of weight on the front wheels, adding a large front swaybar reduces understeer and the suspension changes should be made from there based on a mostly neutral setup. For rear/mid-engine, with the majority of the weight on the rear wheels, a rear swaybar is a must to get the car neutral handling - which sometimes doesn't require a front swaybar if the anti-dive and roll center are correct on the front suspension. This is a highly simplified explanation and many factors play into suspension setup than can be explained here.

There are lots of websites that have in depth discussion about this and some suspension simulator software that can help with the information.
