Road/Race Prep - Fuel and Cooling

Using the available frontal air space designed with the side mounted oil cooler makes the most sense to me. I like the MAP kit with the setrab cooler for sure. I thought letsgetthisdone had fitment issues and MAP blamed your car ? Maybe I am confused.
I could just try throwing a SPAL fan on the OEM oil cooler like I did with the SST cooler. Sounds like that might just be an option. No one is screaming that sky high oil temps are a common problem with the EVO X on the track.

I added the fan to help cool the car down in the pit area. I don't think it would provide benefit while I'm moving. In fact.. I was hoping it wouldn't hinder airflow while on track. So far, so good.

letsgetthisdone - yes please do post the part number for the setrab cooler that comes with the MAP kit. I can cook up a bracket I am sure.
Also I wanted to discuss more the fuel starvation issue. I have decided to try something a little bit off the traditional path. Instead of a full blown surge tank, I am looking at doing something similar to what Chet did with an in-tank mounted OEM pump lifting fuel from the passenger side to the drivers side mounted fuel pump. Radium makes the pump to barb adapter for 85 bucks and that is the most expensive part required. I bought four Walbro fuel pickups (3" round each) that close when they are starved of fuel. There was a deal on amazon and they were basically 70% off. They do NOT work with E85, but I am sticking with 93 so that's fine. I can connect all four of the pickups with gasoline submersible fuel hose and then to the OEM pump that will be run at 9v (Chet did the same low voltage since there isn't fuel pressure to deal with). The pump will then dump the fuel in the OEM fuel pump hanger/basket.
The cost to build this is around 200 bucks (already have OEM pump). My plan is to mount a power switch so I can turn on this 2nd pump when at the track, so it won't just be running all the time on the daily.
For my low-ish power car (400whp) and low(er) fuel demand due to 93, I feel a full blown surge tank would be overkill.
I will post pics in this thread as the parts come in, and install this in the tank.
Anyone see any big issues with this concept?
Like I said Chet did similar with success I read, but he used the Holley Hydramat which is very expensive.
The stock venturi and passenger pickup just seems to be complete crap and has bitten a lot of track guys.

¸I am doing exactly the same... additional pump in the passenger side filling the main side all the time. I am using a low pressure 190 lph pump, that is very low amp.. like 2A or so..
No venturi, and no OE fuel filter anymore..
I will do a writeup when I am done... OE tank has a internal 3 litre surge tank around the fuel pump actually.. so with the second lift pump it keeps the fuel around main pump even in 1+G turns... I did some experiments in the workshop first..
as for setrab.. it is easy to fabricate a mount that connects to the OE mount.

kikiturbo - We are talking EVO X ?
"OE tank has a internal 3 litre surge tank around the fuel pump actually"
What did you use for the fuel pickups? I have seen the hydramats used, I am going to try the walbro pickups. They need to be able to go dry, which those two solutions both support.
Last question - What is the fitting for the OEM oil cooler connect points? Is it a -AN fitting or a ORB ? Please specify so I know what I need to order to connect the setrab.

I'll snag the cooler part number this evening.

setrab we use is 50-625-7612
on the cooler attachments are 22x1.5mm, and on the engine 18x1.5 mm thread.. you can get AN adapters for those. I managed to find these industrial ones that are straight 22x1.5 to 10AN with 90 deg bend, and the same for 18x1.5 to 10 AN for the engine side.. this is from Hansa-flex
tank.. no, my tank is evo 9... I have a large writeup on the ful issue but that will wait untill I have the pump system ready.. We developed 2 systems.. one is with 1 extra pump and the other has 3 extra pumps and has a real surge tank.. all inside the OE tank.. the second system requires some welding...
The pickups are normal warlbro pickups.. but I am not using warlbro for the extra pump.. as I said I found a low amp pump as current use is an issue
You cant let the pumps run dry... this is a big NO NO...

I thought it was 18x1.5 to 10 AN for the oil cooler.
I found the right banjo bolts for 18 bucks.
Does anyone know if -8an (1/2" hose) would actually be a restriction?
My guess is that it would not be.
As for the lift fuel pump running dry; with the four walbro pickups I am going to place in the tank, one will always have fuel. In theory the lift pump would never go dry, but up to three pickups can go dry (they snap shut when they are starved). Since this is just a lift pump if it went dry (the pump) for an instant (which it shouldn't) at least nothing would go boom.

Can I have the lift pump dump into the OEM fuel cup (via drilling + fitting in the bottom or side)? Will I have to drill relief holes so it doesn't become pressurized with fuel?

The cup never gets pressurized, it's an open top.
Here is a diagram for a lifter pump solution I drew up awhile back when I was going to go down the same road. Ignore the surge tank part of it.
I have since decided to just get the Radium cup.

8an line is plenty for the stock cooler location, the banjo ends of the stock line neck down to like 8mm ID, smaller than 8an. If you were to mount the cooler up front (between the radiator and intercooler), I would probably use 10an line due to the additional length.
