The Rotary Extreme regular V mount is also featured in the same issue on another drift FD. It's pretty nice to get free exposure without paying a dime.

For this Turbo, I need 1200CFM+, I need a 4" core, 3" piping in and 4" piping out, I prefer vertical fins, needs to be setup for NO battery (remote battery), NO Y-pipe (single turbo), and NO intake. It would be nice if the sucker were as wide as possible, across the area where the intakes and battery goes.

Yes, this of course means that the end tanks on the top and bottom rather the sides.

Tony:



If you want the top and bottom end tank, the core size will be greatly reduced and you won't be able to find a core that flows 1200cfm in that configuration.



The maximum length from top and bottom is 12". So if you want a 3" inlet pipe and a 4" outlet pipe, that will only leave you with 5" of core. You also need some space on the end tank to weld the pipe so that will leave you with a 4" core. I don't think any company makes that size and flows 1200 cfm.



Spearco does have a core that's 24" wide so you will need to relocate the battery to the back. Unfortunately, that core does not flow as much as the core I am using. The core I am using is the second highest flowing core made by Spearco. The highest one flows 1500 cfm but it's too tall.



I don't think a 4" outlet pipe will be a good idea. You will lose a lot of air velocity. Besides that, I can't find a place to mandrel bend 4" pipes.



What turbo are you using that requires 1200 cfm and 4" outlet?

I am working on a monster v mount II using a 1400 cfm core enough to support 900 HP. The core measures 11"x19.5"x4.5". There is no way you can out flow this one and best of all, I am keeping it at the same price.

Chuck,



Do you think that the GT40R would outflow your original Monster V-mount setup at 20-22psi?? I thought that it would be more than sufficient. If not then please let me know. I do love the way your V-mount setup looks in the car though. I just can't decide between the mini battery and a battery relocation. But kudo's to you for your work with the FD!! Your products kick ***!! I have seen a few of them in person on people's cars and they are just as good in person as they look on the website. I'll be buying tons from you as well as A-Spec. Actually you two combined are going to get my next 2 years worth of paychecks pretty much!! Anybody up for a package deal for a hard working Air Force mechanic?? Laterz.

Okay, Chuck. How about 3" in and out?



So, the max is 12" of vertical space. What is the width of the large/hiflo core you're getting? Then add end tanks? How much wider than the current one on your site?



How about a group buy price with under 100% profit, too?

Zero R

Chuck you can't find anybody to bend 4" that's too bad for you, maybe we can work something out like you stay off my thread and I'll bend your 4" pipe



Tony 4" out wouldn't be that good of a idea you will lose velocity, you are right though in wanting a vertical setup instead of a horizantal one,Tube length is one of the biggest considerations, a tube twice as long as another will have nearly twice the drag at the same velocity. Entry and density also matter to a degree.The most ideal configuration is position the core to offer the shortest length tube and the most number of tubes. This would optimize core area but the way you would like and what you can do sometimes don't agree.

Very funny Tony!! I have to advertise the TII. After all it is for sale.

There is no way you can outflow the core with that turbo. Right now I am making 3 of them all for the HKS T51R Kai which flows 80 lb/min.



Let's do a little match.



The new core I use is 19.5" wide, 11" tall, and 4.5" thick. It flows 1400 CFM at 15 psi which is about 2 ATM.



1400 CFM stands for 1400 ft3/min = 37.8 m3/min (cubic meter / min)



The dry air density at ATM is 1.22 kg/m3 so at 2 atm, it is 2.44 kg/m3



You take the CFM and multiply the air density at 15 psi will be



37.8 m3/min x 2.44 kg/m3 = 92.23 kg/min = 203 lb/min



So with the calculation, it shows the core can flow 203 lb/min at 15 psi. I doubt your turbo can flow that much.

It will be way more than enough for your turbo. See the calculation I did for Zach.



3" inlet and 3 " outlet is more than enough. Even if you use a 4" outlet but your throttle body is not 4", it's going to create turburlance. You ended up losing air velocity. I know it looks cool but things have to match.



The width of the core is 19.5" and with end tanks, the total width is 26.5"-27".







Group buy price is possible if we can get 4+ buyers.
