Where did you have the work done and how much did this cost? I would love to see a before and after dyno! Looks good! I wish i had one!

I got it done at Polk Performance in Benton, AR. Everything was made form scratch except for the IC. There isnt an AWD dyno anywhere close to here, but they are getting one in August or September, so believe me when I say I cant wait to dyno my car either. Because this was the first kit they made, sort of as a doner car, I got a deal on it, but I dont know how much the kit is going for now. Dave, the owner of the shop, asked me to let anybody interested in the kit to call the shop. Their hours are Monday - Friday 9am-5pm central time. The number is 501-778-7223.MississippiSpd6 said:Where did you have the work done and how much did this cost? I would love to see a before and after dyno! Looks good! I wish i had one!

The lag is barely noticable, maybe 100 - 150 RPM's later. No heat soak and no CEL.buit9110 said:

Lag really has nothing to do with the length or volume of the intake.
A Turbo can create volume and pressure in milaseconds. It will not be noticable.
What might be noticable is the reduced pressure drop from having less restriction in the system. (More Chanels, Bigger Chanels in the FMIC vs. TMIC)

They are a good group of people. Dave didnt give me a price to give to the public, but you are more than welcome to give them a call. Go to their website (polkperformance.com) and give them a call on monday.AWDTerror said:

No, I popped it before I took the picture. I will get a better and updated picture tonight or tomorrow. That way you can see how the bottom factory splitter fits perfectly now.late8 said:

I am still working on getting the photos developed that have the bumper off. If you have ever had your front bumper off, picture this. If you place you hand in the center of the bumper support and feel the back side of it, there is a hole. What he did was drill a small hole in the bottom of the support and put a bolt through the hole and screwed it in the top mounting bracket that was welded to the intercooler. As for the endtanks, they said it was just aluminum, nothing special. Here is a picture of the intercooler, so you can see the mounting bracket.jbspeed6 said:

So can u use any FMIC that you can find? I dound one on EBAY and it seems like it would be WAY cheaper to get the parts all seperate then to have to spend the $1100 on the kit. Im still trying to learn the turbo thing so please help. By the way man that looks bad ass!

Thanks man. Me personally, I dont want to cut any corners with this car and I wanted to do everything right, so I wont be using e-bay at all for this car. I just dont trust and prefer not to try to go the cheap route and then something possibly go wrong. The piping was all fabricated and the intercooler is a yonaka intercooler, straight from their shop in canada. Its really all about what your budget is and what all you are willing to do to have the best FMIC with that budget. With the piping, I'm sure ebay wont hurt, piping is piping, but as for the intercooler, I would be very careful on where I decided to get that.AWDRACER6 said:

If you want to you can get any intercooler. But if were up to me I wouldnt just buy any intercooler. There are a lot of variables that you need to look at in a good intercooler. The type of design, pressure drop, efficiency, and what the intercooler is able to support are the main factors to look at. Thats why I would not advise using ebay for an intercooler. Do your research before rushing into a project like this. Like the intercooler I got has a 1-1.5 pressure drop, pressure tested at 30 psi, bar and plate design, and is able to support 350+ HP. The guys that built my kit for me have been very impressed with yonaka and have used their intercoolers for a lot of kits, so they know the intercoolers are capable of the power thrown at them and do a great job of cooling the air.AWDRACER6 said:

Yes there is such a thing as TOO big. If you have a really large core you can have substantial pressure drop between end tanks and that would be a bad thing. You basically want large enough to cool the gases leaving the turbo but not too big as to create lag.
You can test your intercooler's efficiency to make sure it is sized right for your system. Use a digital thermometer to measure the temperatures at the compressor outlet and the intercooler outlet after a WOT run past torque peak. To calculate intercooler efficiency,
E = T1 - T2 / T1 - TA
Where E is the efficiency in percentages, T1 is the compressor outlet temperature, T2 is the intercooler outlet temperature, and TA is the ambient temperature. Assuming T1 = 250 degrees, T2 = 100 degrees, and it's a 70 degree day,
example would be:
E = 250 - 100 / 250 - 70
= 83.3%
Factory intercoolers usually have fairly low efficiencies in the 50-60%. Air to air intercoolers with good piping should be over 80% efficient while water to air intercoolers with an ice tank for drag cars can get higher than 100% efficient.
