It's pretty tight in that spot but has anyone done a "powerpipe" type inlet? I'm wondering how much of a restriction this is at higher airflow levels.
For comparison's sake, the fox body mustang vortech kit doesn't appear to be as restrictive as this one. When you add a powerpipe(large diameter inlet tube) to that kit is usually responds to the tune of 3 to 4 lbs.
It seems like we'd have to remove the doghouse to fit anything bigger on there, but hey, it may be worth it if it'll give several pounds of boost.

The shop I utilize did one for me about 4 years ago. When the stroker was installed it took us several weeks to finally grasp that the stock Vortech intake tube was too restrictive to feed the beast. 4'' U bends were used to fabricate the new intake. It does the job well. At the end of last season we were pulling 596rwhp. No I can't provide you a picture. Others have done the same.

Did you send it in the same direction as the stock piece?
Can anyone else post pics of their setups? I'd love to see how shops get this type of setup to clear the radiator and fan shroud. Thanks for the response!

I suspect that RVY's real problem with the Vortech air inlet tube was not its' size but the 'spin' it imparted to the air as I noted in earlier posts. I suspect that if RVY had been aware of my anti-rotation vane for the Vortech tube that the fabrication of the custom air inlet tube would not have been necessary - however there are always several ways to "skin a cat". Regards, Greg
I made one that was meant for a T trim. But as Greg mention the incoming air that is actually spinning as it enters the blower can cause less boost on the outlet side of the blower. Greg modifys a stock inlet with a straightening vane which allows the impeller to "grab" the air to more effectively compress it.
The housing I made had much more volume and was fab'd from sheet alumuminum. I haven't installed it yet as the engine is still sitting at the machine shop. So I can't say how well it will work.
I'd like to see pics of something like that tj. I currently have the anti rotation plate in mine. I'm mostly interested in ideas for increasing the volume of the inlet tube.
I really want to do everything I can to max out my current S trim setup before going up to a t trim.
There's still two issues for me to work on before going to a t trim.
1. belt slip. I still have a 6 rib. Greg's setup is the answer to that. I'd like to be able to obtain accurate datalogs about the differences between the s and t trim units.
2. Remove all inlet restrictions. This will limit the t trim addition more if I don't do something about it.
so has anyone run the car without the tube on, either on an engine dyno or chassis dyno to see if there is a difference? I have speed density, so I would if it wasn't such a pain to remove and reinstall the part.
RVY- talk about a tight fit. I measured and on mine I only have 3" between the blower inlet and the fan shroud. Did you move your fan forward or cut into it to get it to fit? I bet you could fit a 4 1/2 inlet pipe if you cut it.

Anyone replace the vortech inlet pipe completely?
