been reading up on how Flow benchs work
check out this site if you wanna make your own
http://www.tractorsport.com/cgi-bin/forum/...n/ikonboard.cgi

a prototype of the bench i put together from random stuff around my house

to test my prototype i flowed my exhaust at a low lift of .1"
i was able to test the exhaust side to ~53cfm @ 28" @ .1" lift
based off known VG30E head tests of around 50cfm @ .1" lift.... this tells me my math is right on and the bench is fairly accurate.
 based off a 78% of a 13.5 inch pressure difference across a 1.2inch orifice

my scale is only good for 71cfm which is 13.5 inch rise on the incline manometer with no test piece.

but at .4"lift intake side i was able to pull 24" h20 on the vertical manometer with the orifice removed  which puts me at an approximate max of ~500cfm at 10"h20 test pressure

this makes my current motor capability between an sf-260 and an sf-450  
(the more vacuums i use, the higher the capable cfm at a reasonable test pressure)

picked up some 3/4" mdf today to make a more solid and leak proof test bench
and i'm getting some calibration plates from the PST forums to get within 2% accuracy of a professional bench

Size of the pics are crazy big man...

I don't think you can accurately say it's the same as another one... to many variables. Same as chassis dynos. No two dynos will give the same results so if tuning you should keep everything on the same machine. What you can say is that if you make changes and there is definite improvement in flow then you are at least going in the right direction. But only if both tests are on the same machine.

i said fairly accurate...  much more accurate then 2 different dynos

about 14 people sent the exact same plates around to test the accuracy of their home built benches.  they were all within 5% and most are within 2% of a ford factory million dollar bench

see this link for the results of the orifice plate tests.

i spent about 20$ on this prototype and it took about 5 hours to complete

with my results... i think i can say its within 5% of a 10k$ bench for 1% of the price

once i build a better bench i hope to be 2% of a professional bench

Very cool.  Ne laissez pas les salauds vous descendez

That's sick. I got to make one now. Nice work. A vg needs all the help it can get.lol

I should be up and running with this thing very soon

I plan on becoming a sponsor or whatever so I can advertise flow bench time and porting for you guys...

Got a letter from my insurance that says my S12 now qualifies for their Classic Car Insurance program...lol
I'm going to at least check into it and see what it is about and the kicker will be cost.  All I know so far is the insurance company does an appraisal based on money invested in the car( receipts) + white glove inspection and base what it is worth on that.  The bonus is if it gets stolen, or totaled, they pay you the appraisal amount  instead of blue book.

That's actually pretty huge for a nice car like yours. Assuming the additional monthly isn't rape...

KeithNov 18, 2010, 4:24 pm · #10

Yeah, that will be the kicker

I write classic car insurance. I like Hagerty, they are the biggest and will accept cars outside the 60's and 70's. The catch is the car must be something special (like yours) and they have a mileage restriction.

The benefit is you get full coverage with no deductible and the car is insured to an "agreed value". Plus its usually a sweet price.

KeithNov 18, 2010, 9:04 pm · #12

Ahh, sweet job.

I need to find out if they'll third party it out.  From what I was gathering it would be through my current insurance.  I've got full coverage currently (learned the hard way), but no deductible would be cool

Most classic car companies work with independant insurance agencies. The way Hagerty works is they just match what liability limits you carry with your current insurance company. You are required to have insurance else where on your daily drivers. I do know that State Farm is moving into this market if that is who you are already with.

Here in Wa 15k of coverage through Hagerty is usually around $200 a year. Tough to beat that.

how does it work and where can i find build plans for one

Radracer_SNov 21, 2010, 4:12 pm · #16

I wonder how much the monthly is cost would be if you went for it...
