BOLT-ON BOOST DOUBLE TEST 

Best motor tech page on YT PERIOD.

Hi Richard, I’ve really been enjoying the videos lately. Your first videos where kind of short and now they span 10-15min which I like much better. You are able to hit all the key points and explain things well with the longer videos. Thank you for all your research and testing!

Finally some real test on these things, good work as always!

Torque Storm needs to offer a bigger supercharger unit something in the F1-X range

Always fantastic content. We love what you do.

Great format. Considering adding to a 383 I have and this answers a lot of questions

yes a twin screw with a turbo is the only kind of two superchargers I would run

I always wanted to see a Ls rev out to 9000rpm on a centrifugal supercharger.

Wait wait wait, that 408 made 550 hp na with 8.75:1 comp?? That seems crazy good for having absolutely no compression.

Naming a centrifugal supercharger kit Torqstorm is a great example of an oxymoron.

Please do a video comparing more or less cam overlap under boost

More compression should yield better na power. Less overlap would help with the engine holding its boost rather than just being a big air pump?

I want one of these for my little 5.3 envoy denali so bad

4:49 glitch in the matrix lol JK. Love your content Richard

Is there money to be made buying wrecking yard 4.8's, 5.3's and 6's, going through them to make sure they are good runners, rings, oil pump work, porting heads and offering carb or injection as options? Just curious, recently retired mechanic looking for something to keep busy and maybe make a little extra income to supplement retirement, I would think most hot rod guys or track racers build thier own engines but just curious.

just for clarity... a $400 4.8 made 650hp and a $4000 built stroker made 715hp.

Similar air volume = similar power, eh? But less boost on engine taking bigger bites. Extrapolating mass air flow, I'm betting they took in very similar amounts of air.

Such great info from this channel

A little late to the party but I wonder if Richards ever done testes on the powerdyne/ cool chargers of the days of yesteryear

I would like to see any engine run a torqstorm supercharger on pump gas. Run it without any intercooling of any kind. Then, run it again with pure water injection. No race gas of any kind. While injecting water, raise the timing if possible

This is awesome, thank you

Denser charge due to the fuel cooling the air coming into the engine at high rpm?

Hey rich do a twin blower torqustorm on a 6.0 la with ls3 heads and on a de stroked ls

Twin superchargers? How about compound?! One feeds the other! ;-)

Hey Richard. Love the channel. I'm really thinking about the torque storm due to it's relative low cost and good performance on my 5.3 ls, Delta reground SS2 camshaft, gapped rings, ported/polished 862 heads and Holley EFI 102mm TB/elbow/120lb injectors. I'm hoping for 650 rwhp in my foxbody. Talked with Torque Storm and he's thinks it should make good power but not 650. I watched the video on the 4.8 and it pumped out really good power. What is you thoughts? I'm a budget guy so I'd love to see a video of a Delta reground camshaft one day.

Kind of upsetting seeing low hp out of a 408 Vs a 4.8.. they do flow like a P1sc tho 1650 cfm if they had a f1-a competitor I’d buy one cause procharger is they the roof now

If that 408 had a higher CR it would have WALKED that 4.8 .

Would you recommend this product?

What timing, afr, and spark plugs with the e-85 on the 4.8 with torq storm did you run with the truck manifold? I’m currently at 14 degrees right now with e-85 and torqstorm on my 5.3. I’m running the NGK BR7 EF and look good so far with 11.7 afr. But would like to get similar results as to what you achieved on the 4.8 with torqstorm. Thanks

Glad you fixed your fuel pump on your truck did you use a A1000?

I am sold!!! Im getting this kit

HANDS Holdener! 👐

Why would two different engines with different V.E have the same results....

You pulled the bed?! Lol. You know there are some who pull the tank.....

Whith coronavírus doble the power😈😈😈

What's that fuel pump feeding in your truck? A 4.3? Ha-ha, don't tell me it's stock? The irony,

Sell it to me money in hand

Small blower = small power. I'm not a fan of this blower.

Sooo save my money buy a stock 4.8 and buy a turbo and use the rest for suspension and beer ?

Hmmm, double test...lead to disappointment with only one supercharger lol. Double should mean two of them !

at around 3000 bucks for the full kit for my 98 trans am, this is half the cost of a paxton or procharger..what a deal! thanks Richard!

That smaller pulley would have probably made more peak power on that 4.8.

Commenting for the algorithm.

How about a video of your old cars from back in the day....motors...biggest motors tested....test you remember the best... ETC..Thanks for doing these videos!

Would you possibly do a video on vortech v3 sci truck fead kit on a 5.3 lm7 ?

Watched this again. They seem to be right where they were intended to run, 700hp + -. According to the hp and torque curves, the dip in the boost matches the peak on the torque curve. The sweet spot in torque/ rpm for the engine. The supercharger says, I'm pushing the flow regardless of size, try to keep up. Nice.

I really enjoy your videos. I'd like to see one comparing stock and various aftermarket vvt cams on a 6.0 or 5.3. Keep up the good work👍

We need a twin charging test! A supercharger and turbo charger would be awesome

Personally I blame squirrels

Good stuff Richard. If you want to donate some of that used equipment I will be glad to street test it for you

@RichardHoldener lets get a a dyno shoot out of all the new TorqStorms... They now offer 84, 91 and 94 blowers!

Super Chargers are more controlled by space its filling then turbo . smaller the space boost goes up quickly. And all that huge pipe on 350 would probably run 5-7 boost with big wheel 8-10 with small one . or needed 10 to 1 flat tops centerfugul blower being more 50 50 deal my roots actually realy liked pistons too with only 5-7 psi and 76 cc combustion chambers

I want to see a test with a boosted 5.3 with different cams, stock cam, maybe the LJMS stage 2, sloppy stage 2 and something else.

Not really a fan of the torque storm. Your really back at the P1 starter kit from Procharger. Turbo, belt supercharger or larger Procharger is the way to go. 1000hp for a streetcar now days is the norm.

I was gonna ask you to run a torqstorm test but ya beat me to it. This channel is so helpful and the videos are so detailed it's great. Keep doing what you're doing, your killing it👌👍

You are a wealth of interesting information Richard, thanks!!

So the TorqStorm and the Vortech V3 swap kit are pretty much the same price @ right around $3k. What are your opinions on one vs the other? I have an 01 2door GMC Jimmy with a heads/cam, 10.5:1 LQ4 (vids on my page) and am debating on one of the 2. Thoughts?

What kind of ring gap do you run on the junk yard motors. When u open them up.

I'm having trouble with a Torqstorm single sc in a 5.0 sbf with trickflow heads and cam, it wont boost, it reaches 5psi on redline. Tested no boost leaks, 3.25 pulley i'm afraid the engine flows more than what the sc can provide.

Damn. Seen 408s make that all motor damn near

So Rich all the content lead men to going torquestrom so wanted to say thanks

Is there a front sump pan available for a Gen V LT? Or does a GEN III/IV pan work?

Why would someone spend that much to build a 408 and make the compression that low?

Good stuff, can't wait to see what the Twins do!

Not gonna lie dude, I sooo wish I had your job, or at least something close where I could Dyno test all types of parts on all types of engines. Don't get me wrong, I have my favorite v8's (LS & Pontiac 400/455), but I also like and seriously respect everything from coyote 5 liters, 3rd gen hemis to Honda K24a2's and Subaru EJ257's. Definitely gotta respect a little 4 banger 2.0/2.4 that'll rev from the factory to 8200-8500rpm, and put down 450-500+HP with basic turbo, rods and pistons. I'd love to see you testing some smaller, more common economy GM &Ford (LY7 3.6 and Ford 3.7L ) v6's and i4's, with aftermarket efi/TURBOS/superchargers/injectors etc these engines are putting down buku reliable power too. They put these in way more cars than LS's/LT's and can be had cheaper from junkyards, plus they fit soo much easier in smaller cars like Miata/s2000 and on and on. Engines like the last GM 60 degree v6's 3500/3900 are ridiculously compact and easy to swap, add a turbo, injectors etc will put down 500-600hp all day. Just saying that while I love an LS it's a pain in the ass to swap into a miata

Nice, but where is boost curve for 4.8? :)

For the price and what they put out there rely not worth it. They don't have enough flow for a 408 and run out of pressure etc. The price for a Vortech kit is about the same and the output is much more...

What pulley ratios would be necessary to run something like this on a 5.9 L Cummins diesel? At under 1200rpm as a manifold (force fed) setup as twins? --- What kind of outlet temp/ pressure did you measur? It would give me an idea where on a theoretical mindseye compressor map you landed. Thermal expansion pulling Donner Pass tonight my temps were 31°f -2psi (altatude over 6000')ambant 56°air filter compressor discharg 354° at 29psig, at mainifold 52°28psig

The king of testing

I am so glad you did this test. I have 95 impala with an Texas speed 408 with livernois lse heads. I just purchased the torqstorm and I'm happy with those numbers

I like the torque curve better on the 408 with the smaller pulley. the hp on the 4.8 was still climbing with the 3.25" pulley. It'd be nice to see the hp nose over within the rev range. the s/c seems to work better with the 3.1" pulley.

Time to throw a second one on the 408!

How much hp would it make on stock 5.3 with 80lb injectors and 340 fuel pump?

I have been wondering. Great video!

Why does the stroker stroker get a intercooler and a fast manifold and the 4.8 didn't ? I feel like the 4.8 could've actually made the same power as the 408 stroker if those 2 variables would've been matched.

You do the Chevy fuel pump the way I do that's pretty funny it's better than dealing with the straps

I've longed for a Torque Storm supercharger for so long now this test just proves how well they are built

i did exacly what i expeted, they are great and i think they have now upgrate the wider belt system

I had not heard of these torquestorm superchargers. They are pretty cheap.

Woot woot info to get my day started

Have you ever tried a "twin charging" or "super turbo" set up for compounding? I've been wanting to play with it for a while, but life gets in the way sometimes

Have you ever run a torquestorm supercharger on a 440 mopar?

Another awesome video Dr Richard Holdener, finally getting a little sleep I see. Twins seem like the way to go for me.

there's a guy running 2 of these on a 455 Olds.crazy power,but car is a slug

How would it work on an 11:1 compression engine?

Could the difference between manifolds in the 4.8 be the sizeable cam causing reversion in the inlet manifold?

Whats the power numbers on the 3.1 pully?

What’s your opinion on them worth the money? Quality? Better options for the price out there? I’ve seen these and wondered on my ls3.? 2 blowers seems quite excessive.

We just finished a twin Torqstorm Setup on our 408 and put 717 to the rear wheels on our Ultra4 Buggy! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NG_zGriin0Q.html

I looking at the twin set up this company to put on that 540 power adder you talk me into!!! Your awesome content and work is awesome. But video on dwell of long rods is worrying me because already have and was planning to use my dual nitrous set up with 950 carb. on the 540 p.a.... Twin set up is beautiful and not over priced to cover 1200 hp. Fitting it in engine bay of a C-3 may be a challenge...lol. Think be excellent for trips to Kroger with my handicap tag. America 🇺🇸🇺🇸🇺🇸🇺🇸😀😀😀😀

An angle grinder to the bed makes fuel pump replacement sooo much easier....

if two torqstorms is good, three m90s would be great (aweful idea, great click bait "tripple supercharged v8, whats it make?"

Pretty keen on one of these for my 351 Cleveland

Richard you should tune a 5.2l or 5.9l junkyard Magnum Mopar motor... Let's see the potential of a Mopar stock block!!! Just wanted to see...if it would hold boost... Lmk..Sir.. By the way your a best tuner by far..on YT..👌🙏

I would love to see this run on a stock lm7

More power

I was checking out the TorqStorm supercharger page and was surprised to find that TorqStorm themselves got 912HP/747ft.lbs at the crank with the 3.1 pulley on a Methanol fed NON-intercooled 11.85:1 compression fully built 388 (4.125 bore x 3.622 Stroke) LS with 2" primary fender exit headers (no full exhaust) a CNC single TB manifold and big 105mm TB, CNC ported aftermarket LS3 heads with 2.185/1.59 valves, 6.90 lift 248/260 116 LSA camshaft @ roughly 10lbs of boost, 24 deg of timing via Holley ECU, ALL UNDER 7,500 RPM and ran an easy shakedown pass of 8.66 1/4 mile in their 69 Camaro show/race vehicle and saw 8.4 in their future with some fine tuning. They made a point to say that this is the off the shelf LS kit with the same pulley they sell to everyone....nothing special. Color me IMPRESSED.

This is a great test demonstrating that boost levels do not correlate to horsepower when comparing different engines. Also, it is important to note that you cannot just "pulley up" a small supercharger and expect it to make large gains in power. Each supercharger has to be sized to the correct application with expected air demands and supercharger speed. Also to note, the 4.8 Liter had 13 PSI of boost while the 408 CI engine had less than 8 PSI. Yet, they made roughly the same power. This is another example of how boost pressure will differ between combinations, yet will make similar power. I would guess that if we ran this supercharger on a 7.0 Liter LS that made over 700 Horsepower N/A, we would see little to no gain, even with the smaller pulley.

I wonder how much the radius air entry is worth. And would huge radius entry make a bigger difference?

How about a test with and without a vacuum pump?
