STORM BREAKER!! HAMMERING THE 4.3L CHEVY (ASTRO VAN) V6 WITH BOOST!

you know what there's a lot of popular engine combinations out there ls coyote small block of big block ford small block and big block chevy but guess what this video is for the other guys so what exactly do we mean by the other guys well think about this when we're talking about small block chevys everybody knows the 350 the 327 even the 302 but was the last time you saw somebody do a performance build on a 307 a 265 heck even a 283 and if you're talking about small block fords sure we all love a 351 or a 302 but when was the last time you saw a 289 or even a 260. that's right what about a cleveland heck any cleveland better yet what about a 400 m when was the last time you saw a buildup on a 400m i've done those and i'm going to post them that's what the other guys is all about so today i'm going to start out with a 4.3 liter v6 chevy made a ton of them not very many people are hopping them up because it's so much easier just to choose a small block but the v6 works really well so when was the last time you saw somebody put a v6 up on the dyno add a camshaft then add boost that's right we're going to supercharge the 4.3 let's get going in this video i went to the junkyard picked up a 4.3 liter v6 a late model version with a balance shaft now i know everybody has their favorite but i wanted to get this one from the wrecking yard because i wanted to play with the balance shaft motor besides that has good heads on it they flow well and it should make good power to put it up on the dyno i disassembled it we rebuilt it because this motor was actually going in a boat application so we purposely made it a mild buildup now what i did was replace the factory fuel injection because this was a fuel injected motor replaced the factory fuel injection with simple carburation an edelbrock dual plane intake and a matching carburetor i also put a very mild camshaft in it again because it was going in a boat but while we had it on the dyno i stepped things up i put a healthier comp cam in it i'm going to go ahead and put the specs up right here to help this thing make power in addition to that i also decided i'm going to run some boost now i always love the cyclone and typhoon motors that gm did so i wanted to make my own it wasn't exactly like that because obviously i didn't have a turbocharger rather than the turbo i selected a torque storm supercharger and the reason i did that not that i think it's the best supercharger application or that it's better than a turbo but what i really liked about the torque storm is i had a small block chevy torque storm kit and guess what it fits right on the v6 you see all the mounting points for the small block chevy are the same on the on the 4.3 liter v6 basically the front half is exactly the same so my torx arm supercharger kit bolted right up to this v6 gave me the opportunity to apply boost to the little 4.3 so let's get this motor up on the dyno find out how it does find out how the modifications did then add some boost [Music] [Music] in addition to this test being about the other guys i'm also trying out a new webcam so we'll find out how all this works but our 4.3 liter v6 was a 93 or 94 version i went to the wrecking yard we got it from an astro van they're a little bit harder to take out but you'll see a lot of them there i don't see a lot of s10s there that also have this 4.3 liter but lots and lots of the safari vans and the astro bands and stuff so they're easy to find and as i said before i wanted to find a one with a balance shaft they run a little smoother i i've tried a lot of the other 4.3 liters the non-balance shaft stuff and i hadn't tried one of these so i thought it was about time i did i heard that the heads flow really well they make good power so i also wanted to try that we went to the wrecking yard picked one of these up brought it home and what i did was we took it apart and put rings and bearings in and stuff and just put it back together we did some surfacing on the block and on the heads we took a look at the valve job actually turned out to be pretty good just touched them a little bit and all that stuff went back together we put it back together with the stock cam but the one change that we did make is rather than run the fuel injection which we were not going to run we replaced that with a an edelbrock dual plane intake a performer intake and one of their matching edelbrock carburetors i like those especially for this kind of mild application those carburetors work pretty well and we liked it on this combination we put the motor up and unfortunately for me looking through the hundreds of headers that we have at westec we did not have a a set for a v6 now i thought about modifying a set from a v8 to work on this but there was really no easy fix and i couldn't find anything in time to run this test so we ended up running the stock exhaust manifolds and then we ran a section of pipe extending those so there would certainly be more power if i had a true long tube header for this 4.3 liter but run in this configuration as we always do with an electric water pump and the stock small block chevy pump bolts onto that no problem so run with those exhaust manifolds and open exhaust obviously we tune this thing we put a distributor in it and we put an msd v6 distributor to work with this combination of the carburetor and intake manifold and then after tuning the timing to figure out how much it wanted and playing with the carburetor a little bit we actually didn't have to do too much adjustment on this stock combination it worked out pretty well but on this stock carbureted version now of the 4.3 liter our 4.3 liter produced let's see here 282 or so foot pounds of torque and 206 or seven horsepower which is kind of pretty close to what they're rated at i think that this was originally a 200 horsepower version so this combination worked well but now let's take a look and see what happened after we installed our comp cam i'll go ahead and put the specs up here but it was a 224 224 cam so it was a pretty big step up because i'm sure that the factory cam is a 2-0 something maybe even in the 190s so let's take a look and see what happened after we installed our camshaft upgrade you see we got a pretty big jump in power we went from 206 all the way up to 251 horsepower so that camshaft offered a lot of power now as you can see down low bull below 3000 so if this is something you're idling around which is why we didn't use this camshaft in the boat application because it spends more of its time at much lower engine speeds very rarely is this thing running certainly it's almost always less than 4 500 and probably more like in the 3 500 and lower range even at full throttle so you'd want to be able to cruise around in the in the marina and the harvard area and stuff so this wouldn't be a good camera unless you were trying to race to get somewhere in your boat but for our dino purposes it worked awesome we picked up a ton of power with this cam as you can see the little v6 there's plenty of power to be had so now let's take a look and see what happened after we have this combination with our camshaft and install our torque storm supercharger after running our combination with the healthy comp cam and a 4.3 liter v6 now carbureted it was making a little over 250 horsepower and nearly 300 foot-pounds of torque that's a pretty good combination for a v6 you will remember that um before we put our cam in there our stock motor was down around 207 or so and now it was time for some boost as i mentioned before and the introduction to this i installed the torqueform supercharger and the reason for that is because it bolted on i had a kit that was designed for a small block chevy and the kit bolted right onto this 4.3 liter v6 i don't think that the guys from torque storm even had this in mind when they did it but hey we have it we have v6 it bolts on just fine so here's what happened when we installed the torque storm supercharger yes lots and lots of power as a matter of fact i shut this thing off early because it was making a lot of boost i'll go ahead and uh show you the peak boost and maybe even show you the boost curve here you could take a look at it but it was getting a little bit um i mean maybe a little bit out of control and it's important to note that even though on the video that we that we show uh running this thing with the torx storm supercharger we tried running it first with the edelbrock carburetor and blowing through the edelbrock carburetor unfortunately that did not work so we ended up putting the csu blow through 850 holly that we run on everything and that allowed us to make this kind of power and not have any problem the other thing that i didn't do that i could have done is we didn't run an intercooler on this combination and though we were blowing through the carburetor we ran this thing just to make sure that we didn't hurt anything on this because as i said it was eventually going in the boat we didn't want to hurt it so i i put good gas in this thing we ran on 100 octane race gas but you obviously if you had the right kind of carburetor you could you and you're super charging this thing or turbo charging it you could run it with the 85 you could also run it with an intercooler so if i was going a little bit more crazy on this thing i definitely would probably run an intercooler on it even with a blow through carburetor if i was going to run it fuel injected i definitely would run an intercooler and i probably would choose e85 because we would pick up power and you'd pick up cooling and you know e85 is a lot cheaper than race car so it's just a bit much better combination but in this configuration our supercharged 4.3 liter our our faux cyclone cyclone or typhoon motor was over 450 horsepower as a matter of fact it was close to 460. so it made good power and you know you can see from the curve it was still climbing if we read this thing to 6000 rpm it would obviously keep going it's got a rising boost curve so this thing made good power i like this little 4.3 liter and it definitely makes me want to try another one let's get to our conclusion okay guys what did you think about our test on the other guys you know this 4.3 liter v6 now i'm going to do a ton of stuff later on with other engine applications but i thought this was a good start i love the little 4.3 liter v6 there are a ton of them available in wrecking yards also they make pretty good power i would however like to see even more aftermarket support you see this motor is three quarters of a small block chevy so i'd like to see three quarters of the support for this little v6 that the small block chevy enjoys i'd like to see more cylinder heads and especially more intake manifolds with more of that set to choose from i think we'd see more people modifying these and making power but what i want to do later on is i want to go get another one of these motors because i think there's a lot more power left i'd like to do some head porting i'd like to actually put some headers on this thing i'd like to try different cam profiles and then i like to add even more boost heck maybe even a turbo i'll actually make a cyclone motor but for now this combination worked out really well we made a ton of power the motor got put in a boat it's actually out driving around so it all worked out awesome thanks for tuning in guys make sure to like share subscribe ring the bell all keep testing even the other guys
