[@Cliff_Anderson]

I always love the progression that you take with your testing. You can keep adding cam/head flow until you reach the ultimate power potential for that blower, but at some point (probably around 400-425 hp if I had to guess), your gonna run into the problem of adiabatic efficiency; spinning it faster will just make more heat and as a result, air density will decrease. No matter what engine you put it on, it will only move so much air. It'll be fun to see just what the ultimate power potential of that blower is, though, so keep at it!

[@kenedmisten7995]

Hi, I would like to see what could be done with a turbo Corvair. In the old days seemed that people would turbo the poor flowing engines as seemed to offer more power gains then high performance engines. The big valve and ported NA Corvair puts out 140 hp the turbocharged engines put out 150 and 180 hp (not much of a power increase by todays standard). These turbo engines used a small side draft carb to limit boost, a large slow reacting turbo, no intercoolers, no wastegates, no pop off valves, no fuel mixture sensors or nox sensors and sensor feed back loops. The 164 cubic inch turbocharged Corvair engine only made 180 hp. The new 2.7 ford ecoboost has 165 cubic in and makes 325 hp. They say this ford engine will make 375 hp when programed for performance gasoline. In the day hopping up the turbo Corvair without the improved aux equipment meant blowing head gaskets and holing pistons. The turbo power by feel didn't hit till 3500 RPMs in third gear. Modern turbos seem to spool up faster. The intercoolers now reduce knock, waste gates allow for limits on over boosting. Carbureted turbocharged engines could lean out at different RPMs and you would not know it. Could a modern turbo system bring these engines up to close to 300 hp? Maybe even more important could the boost come on at a lower RPM?

[@Emilthehun]

On my 04 gtp , the best combo I found to be was water meth injection, and blower inlet mod. Oh and an awesome tune from tunedbynishan.

Sweet! Them SuperCharger Boost numbers looks like TURBO numbers!

[@jacobburskey3044]

Would be great to see that exhaust comparison later as so many people believe headers are one of the best mods

[@RyanMcIntyre]

Boost is a different story; if you have positive pressure on the intake side, scavenging (via vacuum) on the exhaust side has a negligible effect, as this video demonstrates. The most important thing in a boosted application is simply getting rid of the exhaust gasses as quickly as possible, which is why zoomie headers work so well. Now NA requires many factors to be discerned to the tiniest detail, and that's where an exhaust comparison will make the most sense. In fact, like many of Holdener's other videos, what is interesting to see is what intake manifolds, heads, cams, and exhausts work together to which effect. To that end, however, engine masters on motor trend has demonstrated that headers are headers, and headers with dents and kinks and welds and more dents are still headers with minimal power losses, a surprise to both of them. The lessons I've learned from watching Richard for a few years is that heads, cams, and intake are actually more important to the power curve than exhaust (when talking NA), which he - like me - seemingly accepts as either headers or not, and that boost is king.

[@jacobburskey3044]

@@RyanMcIntyre except the design of the headers available for the fwd engines dont scavenge well at all due to the cross over pipe. The most important thing in a boosted application is charge cooling.

[@RyanMcIntyre]

@@jacobburskey3044 I apologize for not including that in the factors I mentioned, I was mostly focused on the exhaust equation. Of course there are other things that matter with boost, but what I was saying about exhaust is honestly that it doesn't matter (with boost), just get rid of it.

[@3800TURBO]

@@RyanMcIntyre if he did the pulley swap first you would have seen less gains with the pulley. The headers essentially "un corked" the engine. I must have fitted over 100 pulleys and headers in our shop. The headers help a hell of a lot. Notice how the boost dropped?

[@boosted0079]

Yes I agree lol. It's been argued about a lot. I've always understood headers to be a great compliment for engines using a cam with tight lsa. To help scavenging. But very few engines in this world just wake up because you put headers on it. I think most people's ears and butt dynos are out of calibration lol

[@lignesdefuite]

This is great. I like that you did all the other mods and let it trip on the cam and the ports. It'll be satisfying to see how the torque and power curves shift and see that magical "boost down, power up?!?!" take place. Any plans to run a sandwich air-to-water IC? I'd love to see what increased charge density (and timing tolerance) can do on this combination, especially with compound boost.

[@rancherlee]

The M90 really holds back the power, its perfectly fine at stock levels but really starts making a lot of heat with smaller pulleys. I went though everything on a Ford 3.8L SC (M90) with cams, ported heads, headers, and larger intercooler. The thing that made most power, Ditching the M90 and installing V1 Vortech with Ported NA intake setup. Cam + ported heads were worth 40rwhp @ 15psi (smaller pulley) The Vortech added another 30rwhp @ only 12psi and finally got the heavy Supercoupe into the 12's. Should have kept that car and built a turbo for it.

[@simbanugz2906]

I agree I've had my m90 ported, rotors coated, biggest throttle body possible. Heat soak is horrible on these blowers. If you respect the blower for what it is it ain't bad.

[@artthurman3446]

Love the content. Regarding that "radiused" air inlet...In my experience, bell mouths/velocity stacks look great and can create a small velocity gain. However, we have seen that the real value is in a short radius flow, with little to no (inlet air) neck/nozzle. In other words, the boundary air, after the bell mouth with your inlet setup, nearly negates any velocity gain. Mount that same bell mouth direct and you should be able to see that value. It will be small, but not zero. Worthy in exhaust gas flow as well, when transition from resonators and CATs to smaller diameter out pipes. Helps induce scavenging.

[@richardholdener1727]

direct to what?

[@artthurman3446]

Your video shots show it connected via a silicon tube. Looks too long, plus creates a slight transition. Try a butt connection from a short bell mouth to the throttle body. @@richardholdener1727

I had a 98 Grand Prix pace car (basically a 2 door GTP). But with mine I still ran on 93 octane pump gas (that's what we have here in Texas) but it had the 3.4 pully, 1.9 rockers, a throttle body spacer, 3" down pipe and gutted cat. It ran 8.8 in the ⅛ and well into the mid 13's in the ¼.

Same motors what we have in our Holden commodores in Australia I have a Holden Commodore s pack with the same motor we call them manners

My guess is that tells me that the heads restrict the flow... in and out. The headers may be too short to have any appreciable scavenging effect.

[@vintagejoker5088]

What if you add an under drive pulley setup? Would it increase boost even more? Potential heat soak increase? Could a interchiller mod help that?

[@tehcaptainjack]

I kinda want to let him borrow my ported aluminum heads to run testing on, I’m sure he’s to far to drive my car there 😂

[@timothybayliss6680]

At 2:32 I'm guessing that wasn't magic smoke escaping from the crankcase but some other form of smoke from the longtubes.

[@Itsarealone]

It would be interesting to see you test the zzp intercooler block for this blower! There's a guy that jist installed one on his 3800 swapped Fiero and he is going to a very small pulley so excited to see what it ends up

[@richardholdener1727]

see the intercooler video-that is up

[@Itsarealone]

@richardholdener1727 I had seen that one but the tune wasn't right on it from what you were saying in the video and believe it was on the l67 engine

[@jplperformance9073]

I love these tests

[@sdclark11579]

Maybe I missed something but it wasn't mentioned that anything smaller then a 3.4 pulley means you'll need additional upgrades to run!?

[@richardholdener1727]

additional upgrades?

[@lindsaydempsey5683]

For the higher boost on E85 it would be interesting to see what happens if half the fuel is added to the blower inlets to provide some additional intercooling effect. Could that be done without throwing off the individual cylinder AFR's too much?

[@richardholdener1727]

not sure on distribution

[@zokusharuuku1091]

Love the 3800 but what transmission can handle this sort of power? Preferably manual.

[@richardholdener1727]

FWD?

[@marcusbutzin8368]

Will the 3800 fit in a 4X4 JEEP XJ with supercharger ON THE ENGINE? Can this engine be turned lengthwise and hooked up to either a manual six or seven speed or a normal Automatic? I need lots of horsepower and great low end torque, no I don’t want a diesel! Thanks for considerations! Love the channel, saving the vids to binge watch!

[@kouriedonahoo1940]

Richard the common lore around long tubes on the 3800s is that in order to drop pulley sizes and not produce KR you go long tube headers.....then cam.....then intercooler.. This is also based on the premise of pump gas. Using dyno water, and nearly open exhaust is not going to show this. KR is a common issue with these engines in an actual vehicle.

[@richardholdener1727]

I am not testing KR limits-I'm looking at power

[@stevennunez6013]

Can you do a Ford 3.8 supercharged v6 from the Ford thunderbird s/c Or a Ford pinto 2.3 turbo

[@stuartwinter2758]

The headers arent for power. They aid in keeping the top end of the motor cooler so the ecu doesn't pull timing on warmer days. You can cook a steak on the top of an m90 run in traffic on a 30deg c day.

[@inspector13jjf]

I don't understand the hate for V6's that you see a lot in the car community. Sure they can sound kinda buzzy sometimes and they don't make crazy power stock (they are smaller engines than a lot of V8's) but they do make decent power. I enjoy my V6. It makes pretty good power and sounds pretty good too.

[@boosted0079]

Hey Richard, I'm sure you have all your test plans figured out, but there has been some big debate in various 3800 groups about headers. I've always argued that they aren't power adders, but more of a compliment to get the most out of a cam with tight lsa numbers for the scavenging affects. Others argue that they can help reduce kr on builds running pump fuel. Curious to see if you might do some various cam testing with and without them headers? I love watching your stuff. Satisfies my curiosity lol. I personally am hoping to see some results using water methanol injection pre-blower running 93 pump fuel. This is also an option some guys use, but mostly gets ignored. Not much info available. I have a top swapped 3800 build that I'm considering water methanol injection on. I have zero clearance for an intercooler. Take care and keep testing! 🤘

[@richardholdener1727]

I would like to revisit the header test at a higher power level (with a cam)

[@boosted0079]

@@richardholdener1727 I think that would be great. I mean it's only fair lol

[@NatoriousGamePlay]

Would love to see what a ported blower does for this engine

[@jimc2298]

Gen 3 ported is still a turd compared to a Gen 5 (from what I've read). I've wanted to do the swap but it requires a few extra parts
