The engine is a 292 Chevy straight six, going into a 1949 Chevy Pickup on a 1993 S-10 frame. Turbo route: Holley 500cfm 2bbl, Clifford intake, lump ports, 1.94int. and 1.60exh valves ross pistons, 8.5:1 compression, Tom lowe's turbo manifold, TO4B Turbo and here's the cam specs: intake: 268* advertised duration, .304 cam lift,114* lobe center. Exhaust:264* adv.duration,.296 cam lift. N/A route: Edelbrock 500cfm 4bbl, Offenhauser intake, lump ports, 1.94int. and 1.60 exh.valves, Ross Pistons, 9.5:1 compression, clifford long tube headers, and here's the cam specs: 274* advertised duration, .320 cam lift,110* lobe center. or go to: http://www.englecams.com/downloads/2010_engle_catalog.pdf and page 12 or 14 for the 292 cams. the turbo one is: TCS-5, and the N/A one is: EP-22HYD I've done the math and the naturally aspirated it would cost around $2000 with shipping, and Turboing it would bring it up to around $2600. naturally aspirated it would be around 300hp and 300 ft.lbs, and turboed it would be 350hp and 400 ft.lbs. is the extra $600, planning, tuning, and general messing with worth it? I'm capable of doing both, but this is a budget I6 power build. I want to get this on the road in 2011 just in case Nostradamus was right It's tempting to just make another 383 or 400 like everyone else, but I hate seeing V8's in EVERYTHING!, but they're sooo easy and cheap
It's mot the extra $600 I'm worried about, it's all the extra stuff like modifying the carb for blow thru, messing with timing, playing with turbine and housing sizes, and other stuff like that. If I ran it N/A people always say never to go above 9.5:1 compression with the stock head, why is that? I'll run studs and that stuff...
Heck... if youre going to turbo a 6... you might as well find an 86-87 Turbo Buick motor (LC2)... EFI and turbo... Personally, I'm putting together a '54 235 for my 46... N/A, triple carms, and 8:1
my true plan? is To run it of course, I want lots of getup and go to surprise the other redlight racers, and to ultimately smoke the S-10 guy(long story...) who, as I found out yesterday, doesn't have a 4.3 it's the smaller V6, a 2.8 I believe? He's arrogant and thinks he is the best and says he has a 454 in it... Anyone who pops the hood knows he's only fooling himself, he's missing 2 cylinders and around 250 CI... long story short, I want a daily driver that I can also have some fun in...
I finally drove Elpolacko's Twin turbo'ed truck last month.... Holy*****! I'm sold! I know that isn't the level your playing on, but talk about instant, tractable horsepower this second - wow! I've toyed with doing the Plymouth for a long time, but now I consider it mandatory.
you might do a search (google , here ..?????) on a 37/38 chev coupe with a turbo inline 6....tan colored car and pretty fast (11's from what i remember) boost seems to be pretty addicitive...we're messing with a small procharger on my nephew malibu....picked the car up almost a second and half with 6 pounds....just plumbed in a small shot of nitrous for a intercooler effect.....went 11.80's with 3.42's and 3500 pounds , spraying in high gear with a 20hp jet
You could always build a*****-thru system, instead of a blow-thru. Then, you really dont have to mod the carb and it will be more period correct. Im not sure when then blow thru carb systems showed up, but the***** thru's came first.
what if I went with a blower? it's the best of both worlds, simple setup, lots of power, and it just looks cool. maybe an eaton m-90? I may have to put a body lift on it though, kuz I don't want to ruin a perfectly good hood so everyone can see it... What about the McCulluch blowers I've heard so much about? are they good? bad? easy setup? expensive? it'd look period correct... <!-- / message --> <!-- controls -->
or could a diesel blower work like whats used on a v8? it wouldn't be big like a 6 or 8-92, but maybe a 4-53 blower?
I always liked this route.... not even sure where I found this photo but I keep it in my "car*****" folder...
here's the link to the McCulloch guys....those are quire pricey... http://disc.yourwebapps.com/Indices/131168.html#560
Maybe McCulluch is off limits, my wallet started to tremble when I clicked that link, that would take the total build to around $3000~ not what I call a budget build...
any of those diesel blowers straight off a diesel wont do anything for boost.. they lack the teflon seals on the end of the rotor lobes. those blowers were meant to push air into the 2 stroke diesels because they didn't make enough vacuum to do it themselves..
Right, they make kits with the seals adapters, and pullies to convert the bigger ones and I'm sure the smaller ones too.
Now that I think about it I have a 6-71 blower on the shelf ready for street use, could I just gear that down to about 70% the speed of the engine? Theoretically that would put out around 298 ci. (6x71=426x.7=298.2) just saying because I have the 6-71 handy and it's freshly rebuilt.
I do have A 6-71 blower Handy, and I think I'll try to use that. I'll probally have to mess with pullys to get the right ratio. Here's how the thread is going elsewhere: "There is a guy on the here running an 8-71 on his 270 six, so I was thinking my 6-71 would probably work fine. I'm not looking for a full out race motor, but I want to be able to show those ricers what a real hot rod looks and sounds like If I get 350HP and 350ft.lbs I'd be happy, It'll top at about 10psi boost and 6000 RPM, and It's going to be a daily driver anyway... Could somebody you please suggest some cam specs for me? That'll have me running a Holley 600 (http://holley.com/0-80592S.asp), Clifford intake, lump ports, 1.94I/1.50E valves, Long tube headers, Ross Pistons, and the 6-71 Blower. "
Larrowe truck parts makes a blower manifold, but I don't think your 6-71 will fit. I would definitely go with the blower build - I very nearly went that way with mine. My brother has a blower motor and I was all "turbos are better, blah blah blah" until I drove it. Blower motors make women's******** wet and other men's*****s shrivel.
Using outside air to feed the carb(s); 8-10 # on an 8.5:1 engine should be okay. Usually. Guys run a lot more than that, but the more boost you run, the easier it is to find where that line in the sand was... They say the whole deal w/ boost is about managing temperatures. Coolant temp, oil temp, exhaust temp, and most especially intake air charge temp. -Bill
Instead of fooling around with all this complicated stuff like turbos and blowers, just do what I did, get a large cube engine like a 500 cube Caddy and leave it stock and go at it. I built my engine with a mild roller cam and low enough compression that I could run pump gas and it makes a good street cruiser. My engine is not a low buck engine, I blew my lifes savings on the best stuff when I could have gotten by on stock stuff. JB2wheeler
I actuallly do have a 496 bbc and it's cool, but Everyone has a V8, I want a Straight Six that can beat the smaller sbc's
watch the rpm's...... a friend of mine had a 6 banger that went deep in the 8's on a dragster ...heck it went in the high 11's in his 66 biscayne. had crank issues with the harmonics . now he has a bunch of paper weights and some left over parts.
Since the turbo thing is on the fence as far as age here on the HAMB, here is a new sister forum that it REALLY fits into! http://www.dogfightmag.com/
Brandon is right about it holding together,you might out run the rice burners and a couple of sbc but it won"t hold up long to that kind of abuse,if you want something you don"t have to rebuild all the time or pick up the pieces from go with a v-8 or v-6
