I've seen this before in some SUPERCHARGER applications and I was just wondering if its possible to do with the Blitz kit...lookin at the pics there's no port for a BOV maybe we can weld one on????

Sure!!! why not? Just find a spot as close to the throttle body as you can and weld that bastard on.

PMI, but I thought the TB was upstream of the SC, thereby negating the need for a BOV.

You don't need a BOV for a SC.

I Dont know about the Blitz kit but my Friend has a Maxima with A SC and a BOV

What's the point for a BOV on a SC? Ummm seriously? No need....!

Of course it needs a blow off valve. The pulley's still turning when throttle's closed, therefore still boosting. That'll create way too much pressure, that's why all sc's have blow off valves, same reason as a turbo.

what the hell would be the point of putting a ****ing blow off valve if you dont need it. Thats retarded.

ummm.... i think i just explained the need for a blow off valve

I like the BOV sound thats why I'm asking...and dont say "Well its not turbo" I dont care...I know theres a possibility and my car will sound cooler than yurs so ha...

I don't think some of you have looked very close at the Blitz supercharger. Air passes through the filter into the SC then to the intercooler and THEN to the throttle body, similar to a turbo setup.

no need of a blow-off valve on a supercharger. the eatons have a wastegate that bleeds off pressure, but only at low/no throttle. This may or may not bleed off pressure in between shifts, i'm not sure. A turbo needs a BOV inbetween shifts (i believe) because the compressor is not spinning in sync with the engine, so when you shift, this creates backpressure (turbo still spinning hard, and engine is revving down). Whereas a supercharger is spinning in sync with the engine, so when you shift, its rpm is lowered immediately.

I've never seen a supercharger with a BOV.

that, my friends, is what we call rice. cars with fart tips have owners who want their cars to "sound nice" rite?
N/A, S/C..... neither need a blow off valve. so if we put a BOV on n/a car thats rice, rite? and if we put it on S/C same thing...

dont like the idea... sounds weird.... but if u like the sound, why dont u just record it on a cd and play it? :gap:

Why u gota soop up ur car in the first place then....because ur in this FORUM, it tells me ur into sooping up yur CELICA....thats rice too...SOOPING up a Japanese car is what we call rice...or is it just a big sterotype about the cars...i dont know...why put a BOV on a turbo...cuz it needs it...u callin that rice...lemme ask u this...whut makes u think a SC does not need a BOV, or for that matter, what makes u think a SuperCharged car "Rice" with a BOV....learn what the function of a BOV is before u make claims about what RICE is...ur giving me stupid reasons...all u see is the rice aspect and u disagree...oh it sounds like rice huh..I know for a fact there are Superchargers that use BOV for the simple reason that Turbos use them....to keep compressed air from backflowing into the turbo...what do u care if its rice...ur car is japanese...lastly, i dont need opinions cuz i wont listen to u anyways...i just need facts and if its possible

whoa man.. i was jokin..(i even inserted a smiley and everything)... no need to take it so hard... a BOV is to release pressure.... and it happens between shifts cuz something or rather is running at different speeds. i never bothered to learn about turbos, but from what i gather so far.... BOV only used on turbos and not SC. if im wrong its okay, cuz im wrong a lot, but thats what im here on the forum to do. to learn. i have not the time to soup up my car as i am still a student. my mods are just kiddie mods i admit, but im an enthusiast just like u and everyone else here. i stated my opinions and its cool if u dont give a crap about it..... im cool with it. im sorry i dissed ur idea i was only half joking and all in good humor. when u get ur supercharger and u get ur functional BOV to go with it, then i give u props.

and from the time i've been here. its been the general concensus that superchargers dont need BOV so that's what i based my opinions on. sorry if im wrong, but if im right, (TRD celica, oodarkstaroo, and mk2ktoy all said the same thing) then wouldnt u like to know that its not necessary?

sorry for the book....just needed to clear things up.

no hard feelings bro:wave:

seriously though there is only one point in putting a BOV on a s/c'd car.. and thats for the sound.. which yes it can be done, would u be laughed at by ALOT of people, prolly.. but does it matter.. nope not really :)

read the faq n00bs!

Nobody would argue that welding a bov onto your s/c simply for the sound isn't rice, but this whole idea that any modifications to a japanese car is rice is total BS, in fact it's an insult to a lot of people...a lot of SMART people who understand the enormous potential in this class of racing, and who help innovate the after-market industry. So, if anyone thinks all we do around here is talk about rice, then go to a C5 forum....you'll be in much better company :fawk:

I don't know much about eaton superchargers, they might have an internal wastegate that bleeds off pressure. But if you look at vortech's site, all their superchargers have and "air bypass valve" which is basically a bov. Regardless, their needs to be a way to bleed off the boost when the throttle is closed, and not all types superchargers can do that without a bov. So i guess it all depends on the type of supercharger you get.

Sirk_2: i am offended by your violent smilies, please make them quit blowing things up!
......Oh, y'all were talking about BOV's. Personally, if i could get (read:afford) a supercharger for my car, i wouldn't want other people to hear it, i like the element of surprise. But if you want your victim to know that you're about to hand them their ass, more power to you!

i personally love the sound of Blow Off Valves... It has the similar effect of the tail of a rattle snake, to back off... but you won't get too much of the sleeper effect with this kit with that FMIC... I was wondering that for myself about putting a BOV on this kit... I would love to put the Blitz DD BOV on the Blitz SC Kit... but is there going to be enough boost to sound that sucker off loud enough??? oh yea... your car is not anyone elses car... you do what you like to it... this ricey thing is getting outta hand... my opinion of rice is putting type-R badges on something that isn't, etc... flashy paintjobs, body kits, forced induction is by no means ricey

Man, can't believe I didn't find this thread earlier. ;)

My supercharged MR2 had a BOV, stock. I don't know for sure that's what they call it in the manual, but I believe they did. I never heard the BOV, but I believe it's purpose was the same as a turbos BOV. That supercharger was not the typical type either. It was not engaged 100% of the time. It would only engage when needed. I've never seen another one that does that. Mine runs all the time even if producing 0psi. Anyway, I don't know a lot about the BOV on it, but thought I'd throw that out there.

Secondly -- My Eaton 112 has a feature (not sure what they call it) where if the supercharger produces more than a certain psi it will dump the boost, all of it. :mad: It's a safety they've built in. Most Lightning guys have either unplugged the hose that works the dump valve, or they've installed a boost bypass kit. (It eliminates the dump and also the possibility that the ECU will store a code because it thinks that the dump valve is malfunctioning). I've never noticed the loss of boost or the sound. Unfortunately the L is automatic and the s/c does not engage when reved in park or neutral. So I can't just blip the throttle and try to hear it. (I never thought to try it in the MR2. :confused: ) I've never heard anything when I let off the gas though, I just see the needle drop from 10psi to 0psi (actually below 0psi into what they call vac for vacuum).

do you people really know what youare talking about ?have you ever looked closely at a SC?ALL SC have BOV'S. the airgets released back into the air filter and gets recycled which puts warm air into the SC Thus havingBOV releases the warm air into the engine compartment instead of going into the motor.

BOV makes more sense on turbo for the turbo stays spooled and has no backspin wiht a bov, releasing air pressure...the S/C doesnt work the same, it doesn spool ilke a turbo unless you have somethin like vortech..but thats diff...on this type of s/c it would be pointless to use a bov
