Looking good Carter!

Your car is a purposed built monster.

Do you have pics of these things? LOL!! I'm REALLY interested in the dual WG turbo manifold though. I've been wanting to do the EXACT same thing and I'd like to see what's possible. Are the runners equal length? What size WG are you using?

Also very interested in the custom VMIC. How big is the core on your IC? I'm looking to remake my IC for my V-mount as well. I've been wanting to do a vent in the hood like that too.

What is the v-brace you're talking about? And what about the FPR makes it euro style, what do you mean there? Really I'd just like to see how you have all this stuff set up.

I was thinking an english wheel could be used to change the fenders, but I'd been told the metal was too flimsy. Originally I was going to try to get mine done like that too but I went a different direction.

Pretty awesome, man! I'd actually like to see pics of the whole car but I know you don't want to flood the thread. This list would be cool but if you can at least put up pics of the VMIC and turbo manifold that would be great.

Thanks for the interest. I will have to dig up some pictures on the ABS relocation. Here is a picture of the tank install with the ABS unit next to it. I mounted the ABS unit behind the passenger seat next to the tunnel. Also I pulled the ABS ECU from the Left rear and relocated it where the rear right speaker was located. I eliminated all the wiring from the driver side all the way around to the passenger side, the ABS ECU wiring harness basically circled the vehicle. I only had to splice about 10 wires to the unit itself. It was not as difficult as I thought it was.
I will dig up some more pictures, these are not that great for the ABS relocation. Also I used the -3AN speed flex lines with aluminum banjos from the unit all the way to each wheel.

Goals:

Weight reduction, relocate weight to the lightest corner of the car.

ABS ECU = 2.2 lbs
ABS unit = 14 lbs

relocated to right rear corner of car.

Removed 7 lbs of steel fittings, tees, brackets from the stock brake lines.

I have not had any issues with brakes, 2 seasons of racing so far. Well except for the master cylinder failing at NSS last year.

SpeedJunkie:

Thanks, I do have pictures of everything...Just need to find them all. I can post them slowly. I have the next two days off so I have plenty of time.
The FPR is just a compact design, nothing special. just smaller. I guess it sounds cool.

Pictures of the manifold build







I could not find a decent aftermarket fender to my liking so I had someone make some for me. The metal is really thin as you say but the English wheel does a nice job stretching the metal out. The only issue with this set up was cost. It really hurt the pocket.. The pictures do not do the fenders justice. They look stock. But try fitting 315's on 11" wide wheels with stock fenders.





I will make another post for the V-mount set up.

SSM allows custom control arms? Hmmmm

Yes

Speedjunkie pics:

V-mount stuff,

HOOD, stripped of paint and cutting hole for IC vent.



Intercooler, core is 18x12x2.5, I also welded the IC pipes so I would eliminate hoses blowing off at a race.





4" CAI





AFCO dual pass radiator. This radiator is split in the center. The entry is on the passenger side and the water flows over and up to the driver side to exit. I also used the stock fans on the bottom.

Carter is my hero........

[josh18_2k]

soooo you're not allowed to duct after the radiator, but intercooler is OK? sounds like that rule is broken.. (I'm XP btw, same ducting rules)

[speedjunkie]

HOLY fuck I just typed out a bunch of stuff and it's all gone now. FUCK!!!!

I see what you mean about that FPR. I've seen those before but I didn't know they were referred to as Euro.

That fuel cell is crazy. I can't believe it fits under the bin, and I like how it uses all the previously unused space as it angles back. Those fenders came out really nice too! Do you have fans mounted to the back of your oil coolers? That ABS relocation must have taken an amount of work I wouldn't want to do LOL. Seems like it would have taken more than you're letting on lol. I like that CAI too. I was thinking of doing something similar, just not that far forward, maybe just where the filter is beside the headlight. Oh I like that heat shield above the DP too.

I love those short runners. SUPER short. Do you have any problems with oil drainage from the turbo to the pan? Do you still use the front oil drain hole? I have two EGT bungs I'd like to weld in too, looks like there might be room on top of the runners. Not sure if it would be easy to get in there around the turbo to install them though. Did you get that exhaust flange from Racing Beat? Did you use 304 or 321 for that runner? I can't believe you were able to route the WG dump back into the exhaust too, that's awesome. I have so much trouble putting mine back together with just one WG as it is. I'd love to do this though and cut down on noise. And I love the 4" DP, but I don't want to get rid of the resonated MP and GReddy Ti, so I'm not sure a 4" DP alone would be very beneficial. Are you running water/coolant to those wastegates? If so, where did you route them from and back to? I bought the same ones and I'm trying to figure out where to source the water from.

What brand IC core is that? Did you do the same size piping on both ends of the IC? I've been looking at Bell IC cores and I'm trying to figure out what size to get so it's not too big and not too small. My main goal is response. Have you ever used a different IC and different exhaust manifold with that turbo? If so, is there a noticeable difference in response between this setup and that one?

Thanks for sharing!

Looks awesome as always Carter!

Good point but I do not have any "ducts" in or on my car. Also the cardboard was just used as a template (only good picture I had). The final design is 4 inches away from the IC. This means that the hood has a "vent". Rules say hoods are free. Also my hood is vented less than most after market bling bling ones. Thanks for the concern.

Answers for speedjunkie:

Do you have fans mounted to the back of your oil coolers? Yes one 10" fan.

Do you have any problems with oil drainage from the turbo to the pan? Not at all, and I am using the front drain also. I believe I use -10AN on that one.

Did you get that exhaust flange from Racing Beat? Yes

Did you use 304 or 321 for that runner? 321 SS from Burns stainless. everything is 321 up to the 4". The 4" exhaust is 409 and it starts at about the rear of the transmission.

Are you running water/coolant to those wastegates? Not at this time. This is one of my next season projects because I have over heated the rear diaphragm twice at a race limiting my boost to 15psi which = slow. Also I might have to relocate the WG since it is close to the DP.

I can't believe you were able to route the WG dump back into the exhaust too, that's awesome. It was not easy, also in SSM we cannot run open WG's. All exhaust must exit rearward of the rear axles.

What brand IC core is that? Did you do the same size piping on both ends of the IC? the IC is a cheap ebay core, I was experimenting and did not want to spend big bucks on a IC if it did not work. Also it is 2.5" in and out. I think I have pretty good response if not too much sometimes. Bell IC cores would be my first choice too.

Have you ever used a different IC and different exhaust manifold with that turbo? If so, is there a noticeable difference in response between this setup and that one? I have not had anything different, I plan to change something this year if I have time. I went from a stock set up to this so with that it was a BIG difference.

Im loving that exhaust manifold...to the point Ive decided to make it...I needed one anyway.

Thanks Brent. BTW Brent will be testing my new design on my upper A-arms. They are pretty bad a$$ IMO. I have been running mine for two seasons but he will testing then on the track, mine have only seen AutoX's.


And the list goes on with pictures.

The first pic is the custom surge/anti slosh tank installed in the 5 gallon cell. It basically fills itself with the return. If the tank fills to the top I have a drain hole on the top of the tank to drain excess out. The little red thing on the right is the one way valve which is mounted on the opposite side of the picture. I do not have a LP pump feeding this but I can run very low on fuel and still not starve. I have estimated by weight that I have been down to 2 gallons with no issues. Also I have mounted the stock low gas warning light inside the surge tank. If the light comes on that means the surge tank is below half way ( it has never came on). Oh! did I mention that my stock sending unit is still operational.


The second pic is a picture of the fuel pump with filters. I used chevy truck stock filters. If they fail at a race I will not be stuck since every Advance or Autozone has these in stock. Also (Speedjunkie) you can see the custom V-brace in this picture. it attaches the diff cradle to the car and helps with PPF flex (maybe).


The best thing about this fuel pump set up is that the stock plastic cover fits over it and hides everything. I removed it for the picture but I run the plastic to protect the pump and filters from rocks and such.
