Just so we don't continue to plug up Sean's thread with v6 talk, here's a thread for it. I know it's "V8Buick.com" but this is "Small Block Tech" so it's still relevant. Edit: Alright Sean I cleaned up my part on the other thread. Thanks for moving the info here.
Over in my Turbocharging thread we got a little off topic so I moved the info here... Please go back and delete the V6 related posted out of that thread and we can continue here:
delete done . and actually there is a V6 section at bpg.com . i'm sure some of ya already know that . www.buickperformancegroup.com
I see your delete and raise you a delete. Delete done if I missed any let me know and I'll clean it up. ---------- Post added at 09:50 PM ---------- Previous post was at 08:57 PM ---------- I don't know why Buick never used a turbo on the 252 with a carb or EFI. I know Chevy put a turbo on the 4.3 for the cyclone and typhoon S-10 platforms. I would have loved to see a rebadged 80's El Camino in Buick trim with a turbo 252
I think the 252 was Buick's alternative to the v8, and advertised it as such. Being the 'big' v6 with a Qjet, it convinced enough people I guess. I think the 252 had some issues that the 231 didn't have, but I can't remember what they were.
And people think the Civic/Import crowd is obsessed with Turbos, really it's the Buick crowd. Fast with TURBO'D Class!
With good reason! :laugh: http://www.youtube.com/watch?v=3ePvjj36LB8 ---------- Post added at 11:13 PM ---------- Previous post was at 11:03 PM ---------- There's a thread somewhere fairly recent about talk of a single turbo 350 in the G body Regal. You can get larger turbos than stock of course, and I still wonder if it wouldn't be too difficult to hook up the v6 setup to a 350... It wouldn't take as much boost to make good power from a 350 compared to the v6. http://www.youtube.com/watch?v=Q3B_J8D47tQ
Back to the V6 topic LOL!!!!!!!!! :TU: Just joking, I dont care... http://www.teambuick.com/reference/library/baker_buick.php
ha, you know me, Mr. Tangentville. :laugh: Funny though is I start going off on v6's in your turbo v8 thread, then we make this one to talk about the v6, then I start talking about turbo v8's I remember reading about that before, Sean. Thanks for the link.
I owned a turbo with the funky plenum attached off a Pontiac 301 V8. The turbo was junk it was more of a conversation piece. And what I would do is when I went to a car show mostly meet and greets I would park next to someone with a trans am (In the 80's - 90's everybody had a disco Z28 or a trans am) I would take the turbo set up out of my trunk and stuff it under my wheel as a wheel chock just to screw with them. I'm easily amused but still thought it funny.
They were all supposedly '750' CFM up to I think the early '70's ('71 I think for Pontiac and '72 for Buick) when they modified the primaries for '800' CFM on some, while the majority were still '750'. Truth is, They came from the factory with the butterfly flap rods limited on how far they could open. For Buick, it was 70* for small blocks and 80* for big blocks, plus the fact that they would only open up as far as the engine's CFM demand would allow. So all this "The Buick 350 'needs' at least 750 CFM even in stock form" is a misunderstanding. The 750 Qjet only gave around 600-650 CFM for the Buick 350 because that's all it needed. I'm no Qjet guru, but that is my understanding of it.
75-78 odd fire v6s with low port heads had a large 2 barrel about the same size as a buick 350. 79 and up had hi port heads had the dualjet 210 carb. 225 v6 had a large 1 barrel. all the oddfires seem to have a roar noise or vibration when you got rpms up. the 225 would outrun a later 3.8. buick used small turbos on the v6s 350-490 cfm .too small to really perform well.if they would have bumped up compression just half a point the rwd 3.8 would have really been worth it even better if they would have dumped the plastic teeth timing gears. ---------- Post added at 06:34 PM ---------- Previous post was at 06:30 PM ---------- maybe try bolting on 84-87 ported heads on a 225 with a 4barrel carb and turbo blowthru setup would be interesting
Ah yeah the dualjet... I totally forgot about that one. Basically looked just like the Qjet only all it had was the primaries. Or was that the one that was split like a Qjet cut in half...a single primary barrel and a larger secondary?
if I didn't have so many projects I would actually pull the 225 from my special and drop in the 84 "hot air"GN engine I have in that. I have a ta48 turbo ,ported intake,ATR stainless headers with crossover and downpipe. could have gone well with the switch pitch in there now just rebuild with a higher hi stall.
I know the duel jet only came on aluminum intakes, Front half of a quad jet. They came as non feed back and ccc 3 feed back. Kind of stole the idea from holly with the 350-500 CFM 2V carbs. They were a perfect replacement for the ford guys who had Autolite then to become Motorcraft the Holly would bolt right on no adapters.
Yes your right I forgot about the heated phenolic plate. Most people said screw it and put a thick gasket in place of it. I think Fellpro offered a spacer plate to compensate for any linkage problems. But I think any feed back systems used aluminum intakes.
