TDCracing 4" FWI Installed

[gotboost3]

had to modify the length of the top and bottom with a hack saw to accomodate an 9 inch k&n filter ...sounds alot better than my HAI did and performs alot better also...great intake for the price..made a custom block off plate with roof flashing and weather stripping....

looks good

do they make this for the l36

 

[gotboost3]

if you got an l36 in a 97-03 then yes if not no haha

Looks good from the inside, but that is a pretty tight bend near the filter.

Agreed.

That bend might be killing steady air flow too... The less bends and no sharp angled bends the better

How much did that cost you if you don't mind?


I use a local place for mandrel that does 3.5 and 4" tube...and their bends are smoother. Since that is just mild steel, I'm surprized it's not at least painted.

Not trying to dis what you got, but it will start rusting in only a few weeks.

 

[gotboost3]

its aluminized steel so it doesnt rust very quickly i plan on polishing it then clear coating it...or just painting it silver....it cost me 100$ from TDCracing....and as far as the bend its not hurting anything its a mandrel bent 90 so it may be restrictive but not unless im running like 800whp....all the cobra FWI's bend just like that before the filter...i was running a Short ram behind the head light before this and i felt a significant gain when i installed this...colder air made a huge diff.

How does it deal with engine flex?

 

[gotboost3]

just fine im running poly mounts so i dont have very much engine flex....

I've had a FWI on my car for 2 years with no issues. Switching to a 4" 45* elbow straight into the filter soon though.

If you guys want to build your own...look up Boyce Industries in Franklin Park. They do exhaust systems in 3.5 and 4" for Nascar (all mandrel bent).


They always have a large bin of mis-bends in the front, and sell them cheap. I get them for $5-10 normally.

i made one out of 4" aluminum tubing i found on ebay for like $20. i used a 7" cone and it was a straight shot behind the exact same roof flashing thing; no crazy bend at the end. you just have to remove that fender brace like most people do anyways.

 

[gotboost3]

once i get more modded ill prob just cut it to function like a JMB for better flow....

 

[TonzKnock-G]

Dont worry about it.....my fwi tubing from intense and k&n filter did its job no matter how ugly it was. Never had any water issues and it muthafukin screamed in my 04 GenV.

 

[syP]

you know you can make it a straight shot to the fenderwell.. i dunno why every1 makes it bend.

 

[gotboost3]

i previously had that actually haha just like that but it looked like shyt and my maf readings are showing 33.7 lbs/min for this tdc fwi i read 34.3 with the intake like the one above so i dont see a HUGE decrease in flow like everyone is saying...seems to be hardly restrictive....i tried a short ram HAI right after that pvc fwi above and liked the tb response but hated how if i sat at a light for awhile my intake temps got heat soaked like crazy.....i felt a pretty im pressive gain from this intake...i cant complain i broke the tires loose going 25 yesterday and i only have headers none of my other intakes did that....
