Why do you have a dizzy on it?

The cold side pipe looks a little evil but I guess that's the only way with a dizzy taking up a perfect route.

BTW get a filter on your turbo. That screen will only stop birds or mice from gettting sucked in.

I've actually seen this on some over done show cars that see no road time. I don't understand it!!
But it sounds cool when they run one BOV for low pressure and the other one for high pressure. LOL.

there are a few people that run two around here...

not because its fancy looking or "over done"... they run two because they could not afford one huge *** dknoey bov like in the pics in this thread..

All of the local people i know decided to run two for the same reason. They had one. didnt flow enough and the turbo still surged. so now they run two.

one on each side.... well actually the supra has two on the TB side.

I've always wondered about this as well. A local rotary tuner here runs two BOV's as well on his ~450rwhp FD.

Nope, you would want you blow-off valve close as possible to the compressor housing as possible, for less compression surge.

First gen man

No, you want it closest to the turbo. The reason for this is compression surge is the boost getting slammed into the compressor wheel. So all the backed up air in the lines should blow-off right before the turbo. If you have it next to the throttle body, all of the air can get slammed into the compressor wheel.

But if you want most turbo reliabilty, put it closer to the turbo.

It blows off harder there because more surged air can get out faster.

and closer to the TB if you want the air to stay in the piping for more response.

It functions better than one BOV. Alot less compression surge if you run two. Even two small ones will beat one larger one. It's not a show thing, it does work.

Looks good.. I'm assuming that there is ducting to make sure the air is flowing through the cooler/radiator. A vented hood would be beneficial too.

I'm still deciding between a FMIC, VMIC or a W2A Cooler.

First gen man

try tweakit.net for W2A. I been contenplating using a FMIC and a W2A both.

Flem-Ball

Tweakit.net W2A's are the PWR items yeah? They're the ones i'm looking at

What's the theory for using both?

i like the idea of shorter pipes to the IC, rather than a frount mount.... also... keeps the IC from getting damaged...

props on making the setup, it looks good....

how sturdy are the pipes? if they move around, you might want to make some brackets for support....

i was also interested in a setup like this... it seems a lot more simple than getting a frount mount...(installation wise)

i say just cut a huge hole in the spare hood for air flow, or get some kinda of hood scoop and in try to incorporate it as a reverse scoop

good luck with the rest, let us know what kinda power u make, maybe an intake temp gauge?


cheers,dan.

I hope you're being sarcastic...

If you read this thread at all you would have read that he already mentioned he'll have a filter on the turbo....but i understand you missing it, it was on the first post

As for the dizzy, he mentioned megasquirt, and a lot of people are using dizzy's on this setup (only recently has there been a way to control rotary split ignition).

Good job on the V-Mount, i must admit i like that look alot, you might as well use that space for something after you ditch the mechanical fan. I like

If anything, I like the redundancy aspect of it - if one fails, at least you got the other one!

We can argue which placement is better - both have their merits.
Why not go GT-series BB centers and not worry too much about compressor surge?

the pipes are sturdy. they don't move at all.



I'd say a FMIC is a lot more simple to set up. you don't have to deal with moving the radiator and oil cooler, and making all kinds of brakets to support everything.

I'm running megasquirt... or trying to anyway. lol.

lol, that was the idea of the screen.... and also to stop bolts and large rocks.
don't worry there will be a filter on there shortly.

thanks for the comments.

RETed

It's actually a very bad idea.
Due to the mounting of the screen, it's more restrictive than almost any cone filter.
The close proximity of the mesh magnefies it's size, and it poses a greater obstruction to airflow than you might think.
If the screen gets stucked into the turbo, kiss the turbo goodbye.

i ceased to notice that you still had power steering..... but overall, the piping is straight forward to deal with...... no bumper trimming(maybe the underside of the hood? or does the IC sit flush?) no piping through the area that the battery tray is....

but ive never made a V-mount setup, only fmic"s... so i dont know how much of a say i have into this...

great thread, it looks awesome, good luck with the rest...
