Not nice end tanks IMO , think the buschur will work better for ya DSMOTORSPORTS

 

Correct. No one EVER said anything on this thread about a larger fmic not being effective with a turbo upgrade. And a fmic upgrade still is not 100% conclusive to how much gain there is to be had on the stock turbo.

Im just putting my data in for one example. I didn't see any gain on the dragstrip with a Spearco brand IC. Hopefully BRs kit will be better designed than spearco's and show a gain. BUT the big thing in my mind is that noone's FMIC is going to be a drastic gain over the stock ic. It's not like were going from a 4" x 6" DSM sidemount where you gain 30-40hp from an intercooler. Were seeing 10-15hp average at best. Same cost though.

 

matt55,

I am not argueing but my opinion of those end tanks are the opposite of yours. They are too small and not directional, pretty poor design if you ask me.

How much is that Spearco kit?

I saw a Buschur IC on a customer's car at Dyno4mance, and it was very nice. I don't feel you could go wrong with either that unit or the AMS.

Still, even with the lower IC pipe and the AMS FMIC, I barely picked up 3whp. In my application, it still made no sense to have an IC upgrade with the 16G for power.

 

Big bucks Dave, hence why Im getting stuff from you guys now. The cost on the spearco is about $200 bucks more than your standard fmic.

I didn't like the spearco one either, and my limited testing showed it performed worse than the stock ic temperature wise with the same boost pressure. I also saw no gain in mph at the dragstrip on a colder day with the same AEM map.

 

Well 3whp is still better than the stock ic. So the AMS FMIC and pipe did make an improvement over the stock IC and pipe.

I just see it that in your case, your money might have been better spent on camshafts.

 

Oh yeah... that spearco shown on my site....
That was designed, built, and marketed BY SPEARCO. It's not my design or anything, it's spearco's "off the shelf" Evo8 core. Uses the stock pipes.

 

Re-read i said "NOT NICE" , btw i ordered mine from you (Buschur) on tue of this week , cant wait

 

Got it after the cams, exhaust, everything else pretty much. My car's power is about equal to your Evo (but not your Talon).

 

Ahh just noticed DD type dyno. Say no more.

ok..well I guess your in the land of diminishing returns that that stage of mods. Seems to me once you do exhaust, cams, fuel control, clutch, boost controll there isn't any parts that give drastic power gains.

FMIC is like $650-$800 for somewhere between 0-15whp
pipes are likely even less of a power gain for a few hundred bucks

Turbokit is atleast $2300..I want to see if possibly the turbo upgrade is feasable before the intercooler. Want to know if with the stock IC and Cams what kind of power and drag mph gain I can get from the BR440.

once the turbo is on...then Ill reinstall the BR FMIC and do the cams.

 

Interesting thread. I dont have an EVO8 but do have an EVO1. The cooler on the EVO1 was even smaller than the factory EVO8. And the piping was like they tried to make it as long as possible. I bought an upgraded EVO8 cooler from AMS. I was very impressed with the design of the cooler and was looking forward to upgrade day. I think I shortened the intercooler piping by five feet. With adding the AMS cooler and the shorter and better flowing intercooler pipes I was hoping to feel a nice little gain in pull. To my disappointment and utter shock, the car did not pull as hard with the new setup. This is with the stock EVOIII-16g turbo, 3 inch exhaust running in the 15-18psi range. Turbo responce was also not as snappy.

 

uhm... you got an evo 8 upgraded intercooler? that means it's a big one... bigger one than stock evo 8. depending on their design it might be more restrictive (lots of the ic kits are but everyone just cares about size. so with a larger size and more restriction you're filling up more ic. if you're keeping your stock turbo and not looking to go big you should try a smaller ic cuz you need to match your ic to your turbo application. biggie ics are only needed for turbos larger than stock, or try a more free flowing one, that might not get you the intake temps desired but it will give you more flow and quicker boost. i'm sure you don't wanna hear this but try the greddy unit, although buschur also claims to have a well disnged flowing unit. and remember it's not just about pressure drop, pressure drop is due to increase in size and intercooler restrictiveness and you don't know which one is contributing how much in each kit.

 

I agree. I plan to upgrade the piping first and then do a new Buschur or AMS fmic.

 

The Reasosn why the BR FMIC actually nets WHP with the stock turbo is it actually replaces the Lower IC pipe, which is TERRIBLE on the Evo 8, its an instant 10WHP easilly.

 

...so are you saying the standard Buschur intercooler does not net hp?
