Rotary Extreme RX8 Street Time Attack Project Car.

rotaryextreme · 03-15-2009, 12:12 AM

Hi everyone.

This will be my thread that will show a little bit of my life and my project RX8 Street Time Attack car. The car must have full interior and must be registered. The car is basically stock and this thread will show the build of my car as things are added.

I am going to try out with the rookie races first and see how I compare in real life vs. me thinking I'm a bad ass.....lol j/k

So anyways, here is a photo of a FD T04R turbo kit I built for a guy in the UK. This turbo is good for 700HP.

More photos to follow about my RX8 project car.

The folowwing videos will be uploaded as I go to events in this first post.

OK,

So as far as suspension goes, Tein-H tech with Progress Anti-sway bars. I have actually downsized to some 17x7.5 Volk TE-37's.

I went with the Tein-H so that I can get around town, over speed-bump, driveways, to obtain a firmer ride and still lower the center of gravity on the car.

I went with the Progress anti-sway bars because they are some of the thickest bars around. They have three holes on each side so that you can adjust the firmness. I have it in the middle on the front and the last one on the back. This was the best bang for the buck because I got less body roll and it gave more predictability on the cars behavior.

I picked up a set of 17x7.5 to reduce un-sprung weight and to allow me to run a thicker sidewall for more cornering predictability. I now have 235/45/17 on the car and the car is extremely neutral in the corners. I constantly had the back end stepping out and causing the DSC to kick in.

What I have noticed with the new set-up of these three upgrades is less body roll, better predictability and DSC kick in on when I really need it to. On a track day at Thunder Hill I was able to get the cars back out just enough to tell that the DSC was not limiting cornering speed at high speed (above 70mph). At braking (from around 90mph) the car was straight and true. That back was solid at did not want to step out as much at corner entry.

I am running Falken 912's if anyone was wondering. These tires take an amazing amount of abuse and suit my driving style on the track with the cars current power. The factory brakes are more than enough for a stock powered car. But I can tell that they will need to be upgraded to support constant braking from 100mph and above.

I have a K&N intake; I did not notice any gains.

The exhaust is the Rotary Extreme dual cat back. This exhaust does not gain or lose power from idle to 6k, but on the track when your 6k and up this exhaust makes a difference. Both sides are 2" diameter but give you overall 4" diameter. With the small piping the exhaust velocity stays high but since there are two pipes there is enough volume to allow the exhaust to exit with ease. Yes it is a bit loud, but it’s a good loud like a Harley.

I have an R-Magic replica carbon fiber hood, which is heaver then a stock hood, but it allows the heat and air pressure to escape from the engine bay.

Next week’s install will be an install of my new Hymee Enhanced RX-8 Short Shifter and my Hymee Pro-Tuner Software.

The whole reason for getting the short shifter was to allow me to install a higher shaft on the shifter. This will allow me to transition between the steering wheel and shifter faster. With the shorter throw and the longer handle I will be around stock throw again, but with better accuracy.

Next post will show these mods.

Might I suggest if you are gonna keep the stock braking system you upgrade the pads. Try Cobalt Friction Technologies XR-1/XR-5 combo, they are amazing. And almost every ST RX-8 in KONI Sports Car Challenge runs them with great success.
Now I understand that this is your first build of this kind? And that you are just getting into Time Attack? And I see where you wanted the car to still be streetable but you are gonna want a suspension that can be tuned, ie some type of coil overs with dampening control. If a coil over is not your cup of tea, then think about upgrading the shocks. The Tokico D-specs are a good affordable choice, in the same respect you would probably be better off with KONI yellows. A lot of track-aholics swear by them for the 8.

Look forward to see how this comes out.

rotaryextreme · 03-26-2009, 05:40 AM

Thanks for the reply I8U. I do plan on upgrading the brakes. At least the front ones. Redline Time Attack has a street class, that's the one I'm after. Yes first build of this kind, but not new to the parts. I'll take your advice for the pads and use them on my new front set-up when I get it. For me, as of right now, the stock shocks are working good for me. I have a good balance on the car right now and I don't want to change too much until I get some wider tires. I'll probably go with KONI's after seeing tokicos breaking from being over tightend.

Button Willow, ROUND 1

OK. There were 3 of us there. Please chime in you other 2 guys. The other blue RX8 did really good, he had some track tires on. The black RX8 got like a 2.12 I think with those Dunlop Star speed/spec tires. The black car also had some nice volks. I hope you other two guys chime in and give your Info.

I started out with a 2.20 on some 235/45/17 Falken 912's. Tires squealing around every turn. I had toooooooo much tire preasure. Around 46psi hot. I took it down to 39psi and did a 2.16. I took it down to 37psi hot and My final time for the day was a 2.14. Not bad for the tires. I wonder how I'd do on those Dunlops Star spec........

I had the Rotary Extreme dual cat back, BHR coil kit (freaking flawless, never skipped a beat and never felt a loss of power), kn air filter, tein H-tech and progress anti-sway bars.

Alot of poeple were using those Dunlops and it looks like the tire is the shizznizle.

I talked to a guy with a civic Si (the new one) and he had my tires before. He said that when he switched from the Falkens to the Dunlops he gained 5 sec. Now I'm sure he's better from practice, but 5 seconds is alot. TIRES!!!!!!!!!!!!!!!!!!!!!!!!

My next investment will be some koni yellow shocks because my stock front shock are leaking now and those Dunlops. Hopefully I can get this done before the willow springs event, I'll be good to go!!!!

Hey everyone, some of you might not like it, but it feels great for me on the track. With the short shifter and the extension piece, the throw is the same as stock but feels better.

rotaryextreme · 04-06-2009, 11:57 AM

Here is my BHR coil kit installed, and yes the MSD wires do fit in the stock wire holder. They work flawlessly. More responsive in the mid-range and pulls smooth all the way to redline.

bose · 04-06-2009, 02:14 PM

I like this thread, you have mods I want and this will be a helpful way of deciding.

And yes those BHR coils are amazing aren't they? I LOVE mine!

Nice mods looking good...

The first vid of you is great... you looked really good! Where the hell did the integra come from, or worse - where the hell did he go when he passed you and the Z??? Good luck at the next event... you'll catch him!

rotaryextreme · 04-09-2009, 07:50 AM

Yeah, I hope to catch alot of guys when I get some 265's at 4 corners and finish my s/c kit. I hope to be ready for the 2010 season.
