Hey guys, today I was talking a friend who claims a SSV plenum adds 50whp on a FI car. He also believes that plenum spacers, and upper plenum's (APS tall boy , crawford) don't add power, but only increases lag "because they increase the volume of the plenum" ... I'm trying to tell him who ignorant and dumb he is for not doing any research on this topic. He swears by it and says not only will it add 50whp but its uber cool for nitrous.

Please post some of your own opinions so this kid could be somewhat less of a ****tard.

Thanks
Josh

Posted here by someone else.

The SSV is known for not being a good intake manifold because of its cost and the various people who have reported power losses with it has spread like wild fire overshadowing the people the SSV has gained power for. However I think there is a pattern to the people who have lost power and the many people who have actually gained power.

I think you'll find that people who have upgraded their cams and/or headers, and/or ported/polished their heads and then a tune have all had good results with the SSV. The people who have lost power or haven't noticed a difference all have the stock heads, cams, and exhaust manifolds or small TT exhaust manifolds.

The idea is, if the engine can't get the air out easily enough through the actual engine itself, the SSV will lose power.
This also has applied to all sorts of other engines

These people all have cams and/or headers, and/or port/polished heads and have all gained power or at least felt they gained power with the SSV.



vortech, alphawerks headers
gained power from 4500 to redline
would have gained more power across the whole powerband if tune wasn't 2 pts too rich

did some minor mods and gained power all over the powerband, feels the SSV helped

vortech, DC headers
lost power above 5500 rpms, however was way too rich there - possibly inconclusive?
gained power between 2200-3000 rpms - just needed to lean out A/F there back to normal

FI with cams
feels the SSV is a little better than the V4 plenum

him and his mechanic also believe the issue with letting an intake manifold flow more has to do with how well the air can flow through the heads
TT, built long block, cams
gained 17 lbs tq, 26 whp with SSV

These cars lost power with the SSV and they all are running the stock heads/cams with stock exhaust manifolds or smal TT exhaust manifolds. I'm sure there's quite a few more people who have reported losses with the SSV, but from doing my own extensive searching, these are the people I've found who have reported losses.


NA, stock engine, stock exhaust manifolds
no gains felt and no faster 1/4 mile times

I have also come across two people with stock NA engines without headers who posted that they felt a gain in power with the SSV and 2-3 NA people with stock NA engines without headers who said they haven't noticed a difference with it.

For turbo cars, think about the turbos being right there blocking some of the airflow right at the exhaust manifold. Sure the exhaust probably flows great after the turbo, but this would add further evidence why turbo setups lose power with the SSV by having the restriction put so close to the engine itself

Somebody on this board had to reweld a broken intake runner weld on their SSV. They were boosted though...

Thanks for the input i do realize that a SSV on a motor that has cams and head work would add power but that isnt what I was asking this moron kid think is it will add 50whp on a bolt on FI car with a tune and you will not gain any power if you get a spacer or an different upper plenum, you will only increase lag.

Why do we have to tell you anything? Your friend would believe a total stranger on the internet but not you? You must be a really reliable fellow. Why don't you search yourself and find the benefits of APS and Crawford uppers, which are similar to spacers. Check out the Motordyne website. There are plenty of dynos and comparative data on there, and if that's not good enough, none of us really give a shiet what your 'friend' says.
