Just an awesome build man, love it. Never seen a front aero setup exactly like you have. I can tell a lot of thought was put into the build and it looks like a ton of fun! Great job.

fantastic car, and great magazine feature.

Now thats how you build a time attack car

Thanks guys!

Your build looks great!

I have seen a lot of time attack cars with similarly cut splitter end plates. I have been looking all over trying to find out what effect it has since I will be building some soon myself.

Can you tell me what the purpose of cutting it like that is?

Thanks!

powerneedy

The spill plates work by steering that high pressure air from the splitter by not only keeping high pressure air from mixing with low pressure air flowing under diffuser, It helps steer the high pressure air past low pressure air coming from wheel wells (incorporating canards "Vertical" Gurney flaps). Believe it or not, those spill plates can drastically effect rear wing downforce as well.

Caoboy

Is that because they are channeling the air? Instead of just having it blast out the side?

Are you planning on adding gurney flaps? My buddy has some for his Supra, I wasn't sure how they worked, thanks for defining that.

I'm looking at making the Spoon Sports S2K styled fenders to help with the tyre and offset choices as well as lower pressure for my car.

One question off topic I did have, powerneedy, What full sized radiator are you using?

Your kiwi-styled manifold has the same distance forward as my JDL Auto Design,


but as much as my Koyo is doing an ok job, I'm looking at more surface area without "tucking" the radiator too close to the intercooler




Am I missing something here?

powerneedy

Caoboy, from my understanding that is correct. I have lots of things that are on the "to do" list and I am sure they are somewhere on there lol.

TheShodan, I believe that the fenders have drasticly helped my brake temps along with the rest of the areo package working together.

In those pictures your posting I have a afco sirraco radiator tucked away from the LoveFab mini EQ mani. While it was made nice for the amount paid it was just to small and the efficiency was not adequate to keep the high heat car cool. There are also mistakes I made in this picture, To name one the cap on a dual pass should not be on the hot hose side as there is to much pressure there and will constantly trip the cap.

My latest radiator and intercooler is built by All in fab to my custom specs. Keeping heat in the car is the key now lol. I hope that helps haha Let me know if I can answer anything else!

If you would like I can snap a few pictures of the radiator setup. If there is particular angle that you would like let me know. food for thought my setup would work with a stock bumper setup with a few simple tweeks.

That would be fantastic. I'm considering a custom radiator that is full sized to work with the JDL manifold. I have a Koyo Civic 1570 that works ok for the first 30 minutes even with shrouded ducting, but with a new bumper being made, I feel I can get a bit more surface area despite the large intercooler setup. (I have a JDM Front end conversion as well). Which is about 10" high instead of with that cross beam. but the rest of the radiator support was reinforced.

I'll be changing engine management this year as well. so, If I don't get a lot of testing done this summer, its due these changes.

thank you for all the help!!

powerneedy

Alright here they are as promised TheShadon

Fantastic, Powerneedy.. I'll be looking to this after this season. I hope you don't mind me taking the pictures for some reference cues.

Lastly, I have almost all of my new brake system taken care of. I'm just going over some final areas for the rear system. I'm trying to keep that simple,and funny enough will still plan to keep ABS. my question is, what rear brake system are you using? A hybrid OEM? Custom? AP Racing?, Baer, Willwood?

I'm on a hybrid NSX caliper setup now, but I'll be changing to a Wilwood DPHA /OEM hybrid setup for the front. I'm looking the rear which might need some touch ups since I'm running much higher spring rates, more power, and larger sway for a more RWD trailing bias to fit my driving style.

powerneedy

Not a problem sir

The rear brakes are still stock with a fairly aggressive pad. I feel the balance is finally about right with the way I drive. That may change though so who knows lol. Honestly I got rid of abs for trail braking and such but with the way the car turns in now I don't find myself asking for the car to rotate with brakes at the moment and would mind ABS again to put the car into the corners a bit more confidently

Excellent. I noticed that you have a StopTech 4 piston system up front. What size Rotors are those? 12.2", 11.8", etc.

Root of all Evil

Looks like 12.9 from the clearance in the pics. I have the same.

powerneedy

Root is correct.

TheShodan

iTrader: (14)

Roger that. I'll more likely go with an 11.8" or 12.2" since I'll be using some 16" and 17" wheels.

Awesome carbon work! You have some talent!

Another alternative is the route we went. We have a full size CSF radiator that we tilted forward in order to clear our manifold. This required us to remove the front crash bar and make some other changes, but all in all in wasn't that bad. Right now we have an HKS log manifold but we're swapping over to a tubular manifold with our new turbo setup and we still have lots of space. My issue with some of the smaller tucked radiators is that when you calculate the actual surface area it's really no better then a good 1/2 radiator. The only real difference is the location. With our full-size radiator we can run for 30 mins in 40+ degree weather without seeing the temperatures go above 200 degrees.

Here's a couple of shots:

what is the distance (in the center) between the intercooler and the radiator? In other words, how much spacing is between the two?

Considering the front of the radiator is basically outside & in front of the radiator support, how is front bumper fitment? did you make your own like Powerneedy? or some other aftermarket design?

It's kind of an optical illusion, the radiator is actually in the OEM mounts on the bottom and still "inside" the radiator support, it's just tilted forward. We've noticed the lower support a bit, and with the tilt the radiator mounts underneath where the oem latch would go. I use an OEM front bumper, not modifications to it other then some trimming we did for the intercooler (many years ago) and the opening for the oil cooler. It's also nice to be able to use an OEM style radiator, just in case I need something in a pinch I can grab it without having to wait. Here's a picture of the front end:

Nicely done!! So it was a full sized---- which application? Since stock civics appications only came with half sized units.

powerneedy

That's a great option but even though your radiator is minimaly larger in dimension mine is a dual pass making it much more effective. My electric water pump is regulated to control temps and even with it on its slowest speeds if it's a 60 degree day we have to work at getting temperate into the cooling system. It makes it worth it as when it's 100+ degrees in the dry desert the system holds amazing at 200 with 30 minute runs.

which electric pump did you decide to go with?
