THE OTHER GUYS 3800 L32 HOW TO MAKE HORSEPOWER. CHEAP, JUNKYARD SUPERCHARGED V6 POWER (PT 1)

[@richardmorrison6134]

Looking forward to the turbo portion of this series. I'd like to see what these things are capable of.

[@jzlove5088]

The fastest build so far on a turbo 3800 came from my fellow michiganders a couple hours outside of the Motor city. They(ZZP)built a 1000-1300hp mid 8 sec FWD 3800 Grand Prix. I believe they still hold the world record for fastest FWD 3800. I haven’t seen anyone top that yet for a 3800 build. They sell kits that can get a junkyard 3800 to 600-800hp pretty easily. They were doing it with these right around the time the 5.3 and 6.0 craze started. The stock rotating assembly is very strong. I own a supercharged 97 Grand Prix, mine was dynoed at ZZP in Grand Rapids and made 325 to the front wheels, I think it was around 13lbs of boost

@UCQSUgWYbfdQBg8GcBuxgHsw, very nice! Getting close to mid 8s. Definitely up there in the top 3800 builds!

[@jaydubb71]

The boost curve is due to the stock cam, heads and exhaust manifolds being so restrictive. The peak boost will drop with the headers. Ported heads and cam will lower peak boost also. Then you will have to pulley down. My GTP was making 11-13 psi with a Gen 3 blower, 3.4 pulley, fenderwell intake, Speed Daddy headers and SLP loudmouth catback. 17 degrees of timing also. Had to back the timing down to keep the tranny alive...

[@Matt_Lanzer_13]

Ported heads definitely help, but when it comes to boost curve problems, it’s stock supercharger. The m90 is just a tiny blower and chokes itself out. Put a bone stock engine in front of a turbo setup at the same boost levels and it’ll make WAY more power

[@jaydubb71]

@@Matt_Lanzer_13 agreed. The M90 is tiny but right now, that blower is choked with that stock blower. I personally think he should get an NA style upper manifold (that's if they still make them) or gut the blower and use the blower case as a plenum. I really wanted to do that to my GTP but the funds wouldn't allow it...

Can't wait to see the compound boost tests. I was disappointed in Gale Banks compound boost test on the Duramax monster truck project. He didn't measure pressures and temperatures at all critical points in the system so you couldn't tell when the blower was getting in the way of the turbo. When that happens on the 3800, it would be interesting to take off the blower belt and see if the engine picks up manifold pressure and HP with the supercharger freewheeling.

A proper valve job is often overlooked by many . People seem to focus on rings and cylinder walls, but the head is just as important . Good valve guides as well as valve to seat surface, and then of course the correct valve spring for the application. An interesting video would be a worn out performance head against a perfect stock head, as in the head flowed with in a reasonable amount more, but now the valve guides are worn and the valve might not be sealing well. Where is that trade off of better flow vs it inability to seal 100% and at high rpm? It is also kind of a two part question for people not looking to spend much. Gamble on used higher performance heads vs a great valve job maybe some porting to keep the price around the same either way. The second is cheap heads with the same flow numbers vs heads with the same flow numbers , but the valve job is done 100% correct, both brand new out of the box. That almost turns into a third question ... should I just buy china heads and have my local machinist go over them, because just being made in America and paying a thousand or more doesn't mean someone making near minimum wage is not just slapping garbage together.

[@timothybayliss6680]

The t5 should bolt right on, youll need an F body flywheel and pilot bearing but the crank should be the sam in all series II. The series III i dont know if its drilled for a pilot because it was never installed with a manual transmission. All of them are fwd. A series II engine will maybe be more common and probably cheaper in the junkyard and they have the same head castings, the blower is different but not substantially. I still would never swap this into anything. 330ftlbs will destroy a t5 driven hard and the all iron construction means they weight more than a Al LS engine and about the same as an iron block 4.8/5.3. There are so many better V6 engines that gm has made in the last 15 years that are a hundred of pounds lighter and make make the same power without a blower. The Sc points the throttle body at the firewall on a rwd application, i dont know how well it would work in a tight engine bay.I dont think the engine is bad, it is great for something low maintenance and low performance that doesnt burn much fuel. Its a terrible, heavy antique for something you want light and fast.

The newest and last pushrod 60° v6 (3500/3900) is in the same family as 2.8/3.1/3.4 and shares the same bell and some have a manual trans. Street driving or even aggressive track driving is pretty easy on a trans compared to powershifting with slicks on a prepped track. A WC t5 will do lots of magic too if you dont powershift into 3rd on the regular. I wouldnt swap a 90° iron pushrod V6 into anything other than a giant forklift or a generator. They are too heavy and expensive compared to the performance offered by aluminium 4 and V8 engines that share the same bellhousing and crank flange offset.

The dyno boost curve with aftermarket EFI engine controls is not going to be accurate as compared to a vehicle with a stock l67/32 PCM/computer. The stock PCM with stock tune controls the boost via the BBV to about 6.5 psi as I have recorded in my own 2000 GTP. Additionally the stock PCM has "torque management" and "abuse mode" that is also going to limit boost under those parameters. Just finishing up a rebuild on my on L67 right now, stock rebuild, no mods except for ZZP 1.65 rocker to replace my factory rockers to which four of them had started to wear the pushrod pockets. I also found that every exhaust valve was leaking cyl. pressure, and my con rod bearings were just starting to make noises, (reason for rebuild) other than that it still ran great, did not burn oil or leak oil, and had 196,000 miles! The original pistons did not look that bad, but I choose to go with new ones from ENGINETECH. I should be doing the first start after the rebuild the next day or so.

[@jessemurray1757]

Typically you'll see 5-7 at 3000 and 8-10 by redline on stock setup, usually only 3 psi of increase. With a stock cam and manifolds you'll see boost rise sharply over 5000 rpm. With headers boost won't rise as much over 5000. Add some rockers and usually boost doesn't increase much until 5500. Cam, headers, heads, boost is pretty flat, only increasing by 1 psi or so over the run. In regards to your pulls, 9.5 psi isn't unheard of on a stock setup but 4.5 seems a bit low at 3000 rpm, i would expect closer to 6. That front manifold is junk and extremely restrictive, the tubular front is a good upgrade but going right to headers is a better idea. 1.9 rockers is a common swap but a ZZP XP or NIC cam is a better idea along with a set of their ported heads. Heads, cam, E85 and turbo should make some decent power. Not uncommon to make around 600-650 at the flywheel. Just my input.

How did the 3800 get the engine code L32? The L32 is a 60° V6 from the 93 to 95 firebird/ Camaro

[@richardholdener1727]

the 3800 in the Camaro is the same engine family

[@raydemarco427]

@@richardholdener1727 that's what I'm intrigued by. The L32 V6 is a 3.4 60 degree V6. It's a very different engine from the 3800. But shares the same engine code somehow.

Richard, Once You Run Turbo Set Up On This Trying Running ZZP Coil Packs And Granatelli Plug Wires After. I Think It Might Be Surprising.

[@EmeraldEnchantments]

The secret to building a strong 3800 is building a good motor with a good bottom end, high flow heads, good cam good exhaust. Maximum boost at that point should be about 8 lb after that you lose volumetric efficiency

[@jacobburskey3044]

Stock bottom ends have held no problem above 600hp, you don’t really need to touch it. Same thing with the manifolds, and you definitely don’t lose VE after 8psi, maybe 15

[@EmeraldEnchantments]

This is America you have the right to be wrong

[@rdsimmonds]

A set of forged pistons, some good rod bolts, and balance the crank is all you need to do to the bottom end to support upwards of 900+ at the crank.

[@jacobburskey3044]

@@rdsimmonds don’t even need that, 700whp has been made on an l26 with good fueling and tuning. Imagine what the stronger l67/32 can make.

[@EmeraldEnchantments]

And people that smoke have lived to 90 but not typically. A boosted engine is much safer with forged internals. That's why they make them. And show me a 3800 making those high horsepower numbers with stock heads, cam, or manifolds.

[@Christdeliverme]

Contrary to common sense, when I did this back in the day, putting an intake on the blower, I lost boost everywhere and gained about 12 whp. Esecially lost boost bottom end. Is the bypass working correctly? Stock it should hit 5-6 PSI immediately then rise to about 7. Though this was an L67. The interesting part was. Back in like, what was it now 2002? The car would have KR on a stock pulley 93 octane (200FWHP) When I threw a T62-1 with tubular manifolds on the car with a spearco front mount, no tuning whatsoever, stock everything, blow through MAF, I forgot the PSI it was low. 13 Maybe, car made 340FWHP with zero knock. I cannot wait for the blower portion of this series to be over tbh :D

[@GIGABACHI]

Blower is nothing but a band aid and cost cutting measure on this engine from the factory. No heat exchanger, a total and complete cost cutting design from the get go.

[@marqueshairston1173]

What about water and methanol injection

[@derrelcarter9401]

I was just struck by a poignant question, Do you have add ring gap to a factory engine that already had and was designed for boost?

[@richardholdener1727]

I put it at .028-.030

[@derrelcarter9401]

Given what you have planned that is understood SOP even. Just curious as to what the OEM did for a boosted application

[@3800TURBO]

I see 3800. I click. The long tube headers will help a hell of a lot! E85 and nitrous works great on these. I've been there. That boost curve is wrong...... it should be near instant. Very odd.... The stock heads will do way more hp. The cam is the limit.

[@r4raced4doom2]

I wanna see the difference with a nasty ZZP stage 4 cam vs stock! Is your boost bypass valve leaking/stuck open?

[@r4raced4doom2]

Also I remember browsing the forums back in the day and they say the non-supercharged heads flow better than the super charged ones. I've always wondered the truth on that?

[@rogermarshall8991]

A bit late but Hell ya. The V-6 has interested me. However, aftermarket support sucks.

[@salvatorehayes2753]

That Boost Curve Is Pretty Normal For A 3800 Supercharged. Almost All The Supercharged Cylinder Heads Are Cracked Between The Exhasut And Intake Valves At Junk Yard. You Have More Luck With N/A Heads From Junk Yard But You Cant Run The Supercharger On The N/A Heads (no injector ports in head). Good Luck Getting Ported Heads. I Sent My Cylinder Heads Out 11 Months Ago And My 3800 Has Been Down Ever Since. I Just Want My 3800 Running Again. It's A 210,000 L67 Crank In A Series 3 Block, L32 Rods, Diamond Ceramic Coated 8:1 Forged Pistons, Ported L26 Cylinder Heads (if they ever get done), Ported L26 Lower Intake, L26 Upper With Velocity Insert From ZZP, 91 Pump Gas, Water Methanol Injection, Quick Spool Wet Shot And A Big Turbo Cam. And Of Course A Turbo (GTX3582R With .82 Turbine) I MISS MY 3800 SOOOO MUCH lol

[@salvatorehayes2753]

@JPL Performance My Bad It's In Ohio. Lol Indiana Is Where Triple Edge Performance Is. I Had My Transmission Built There And For Some Reason It's Burned Into My Head haha. 4 Years Ago That Took $6,000 And 9 Months To Get Done. But It Was So Hard To Find And Get Parts For The 4T65E (7/8" Chain Set, PI Torque Converter And The Ultra Rare GM Torsen LSD) All My Transmission Is Missing To Be Completely Built Is The Impossible To Find 1" GM Chain And The GM Input Shaft. Once I Hit The 10 Month Mark On The Heads I Started Getting Upset. Now We Are Coming Up On A Year And It Scared Me Becasue It Felt Like It's Only Been A Few Months And An Entire Year Had Flew By. The Bad Part About This Is Money. Since My Monte Carlo Is Down I Started Messing With My 5.7 Hemi Jeep Commander Which I'm At The Point I Wanna Build Up My Jeep. I Threw One Of The Montes Spare Turbos And It's Already Making More HP Then My Monte Carlo Did. Lol And The Jeeps Still Got Stock Cam And Heads hahaha. Granted It's Not As Fast As Monte Carlo Cus the Jeep Weighs 1,500Lbs More. Monte Was Making 480WHP With Almost All The Bolt Ons And ST5 Cam, 1.65 Rockers. Jeep Made 450AWHP ( if you consider the AWD drivetrain losses it's making more chp) And It's Not Even Trying With 7PSI And 11Degs Of Total Timing With Zero KR. It Gains Like 15HP Per Deg Of Timing And Like 30HP Per Lb Of Boost. I Haven't Turned It Up Cus I'm Too Chicken Knowing The Piston Ring Gap Is Stock hahaha. Tuner Was Like We Are Not Even Breathing On It. So I Wanna Do Cam And Gap The Rings Which Is More Money haha. Then It's Gonna Brake The Tranny With More HP And I'm Gonna Have To Build That Up Like The Monte hahaha
