I ahve seen several cars now that have 2 BOV's. I also have heard that he limit for the HKS supersequantal is around 450 horwepower. My engine is still being assembled but when tuned I have a very strong idea it will be a good bit over the 450 rating. While the piping is of it would be nothing to tig another flange on there and add another BOV. What is everyones take on this

 

You could try it,... How many pounds of boost are you planning on running?

 

I ran 22 psi on the old smaller motor. This new one i hope to push it up to 26ish if I ever get it together.

 

Damn what was your times on your old setup and whats your new setup? Just curious becuase I have a 3rd gen. teg and Im building a Sleeved B20 with a custom turbo setup, and im hoping to boost 15psi daily and 20-25psi on track. TIA!

 

Get the Greddy Type R BOV.

 

just get a tial

 

Greddy type r is great for high psi applications.

 

HKS racing, Apex Racing, Greddy Type R and Sard racing all flow about the same. All are good for hi boost/hi hp but low boost springs are available for all.

 

You know, I really like the Greddy type-R BOV. Oh so sweet!!

Ive heard daul blitz BOV's on a supra before.. ****** amazing

 

just a get a damn tial works wonders and is bad *** for the price

 

Boost Pressure is what will determine a BOV's capability, the manufacturer probably knows the max PSI their BOV will handle.

 

This supra has two HKS SS BOV...

 

b18b knows what im talking about

anyone look into the tials? their wastegates seem to be the best... so y isnt anybody looking into their bov's

 

I agree Tial makes some really nice products.

I have a used Tial BOV that looks almost new, asking 200 !!!

 

I was thinking the 2 super sequantils because I already have one and they are only like 180 bucks. I have had no complaints with them and they seem to work good at high and low boost which is great because I switch often with my profec. Just out of curiousity will the Tial or any other BOV use the same flange as the HKS SS.

 

I love my hks ss...i just wish it was louder.

 

It also has 2 Turbos and 2 intake pipes what
s your point?

Boosted3g,
I dont think 2 BOV's would become a necessity until about 20 or 40 PSI depending on the manufacturer. but it would be col to hear 2 BOV's.

zzzzzzzzzzzz *pshh* *pshh* zzzzzzzzzzzzzzzz *pshh* *pshh*zzzzz

 

Yeah it would probably soubnd good but I dont want to go overkill and do more harm than good. I will definantly run over 20psi but I dont know how far. I will have to see how the engine responds. Im planning for around 25psi.

 

I only have one in the same kind.. lol

 

Actually that supra has 2 turbos and a 1 into 2 intake pipe. The intake splits into 2 then each end attaches to the repective turbo. Those 2 BOV's are on the single intake portion.

 

Oh ok then, the picture wouldn't load up on my computer so I just assumed it was stock or something.

boosted3g,
why do you say it would do harm? true that 2 BOVs might not be necessary but if any thing the 2 BOV's would just release the compressed air faster when the throttle slams shut.

 

Both BOV would sound at the same time, they are actuated by a change in intake atmosphere. There is only one engine in the supra right?
