Pushing Vortech's New Blower Kit to the Max with Our Built 427 Small Block [Fixing Old Problems]

[@TheHorsepowerMonster]

An important note I need to mention: Please don't think I am in any way dogging the old shop that helped me with the original build. I don't blame them for any of the issue we had with the block. Yes, the block got knocked off a work table, but stuff like that can happen. And then they took a lot of time and attention making the repair. Everything thought it was done as well as absolutely possible. So please don't think I'm putting any blame on those guys, we're still friends and hope to work with some of them again in the future. Thanks!

[@xozindustries7451]

I would think that they would have replaced the block

[@tomconner5067]

It was the decision of the customer to repair it, and it was done well, there was just and undetected and unsuspected main cap alignment issue that if detected, would have been correctable with a material buildup/re-size, and basic line bore & hone on the rear main cap,while torqued down. If foresight was as clear as hindsight, the welder could have ran the bead with the rest of the block submerged in H2O, preventing the damage with an ounce of effort and it would not have been an issue requiring the above mentioned “pound of cure”. I’ve cross drilled dowelled and siamese drilled and tapped a hole for a small tapered plug, half into the dowel end and half into the ear, preventing it from turning or walking its way out, then cross drilled through both the plug and dowel starting through the ear material ending 5/16” into the block, pounding in a drift pin until it bottomed out cutting them off with an angle grinder with a slicer, then after grinding the whole thing flush,used a punch and a low temp oxy-acetylene tip to heat up the iron i peened the block gently to lock in the dowell , and drift pin before re tooling and repeating the process at the other end deliberately cross drilling at different angles along the linear edge. Once it was fixed, I ground a slight bevel along the crack, and patiently stitched the seam with a nickel 99 electrode filler, letting the bead cool to the same temp as the preheated block/ear substrate. Phew! My thumb is numb! Well it held up, and no one noticed, it was on a 454 block, had a little more meat

[@cassellracing]

[@angelo_giachetti]

I like Vortech blowers and their kits. They work. I was one of the first to buy a Vortech kit serial #00214. It was an A trim for a 5.0 Mustang back in 1993. Later I had it upgraded to an S trim and 10 rib pulleys. This head unit had straight cut gears and it was noisy. Back then few people heard of centrifugal blowers as the only other one was a Paxton SN89 which could not compare to a Vortech. I enjoyed the video.

[@cajunroadwarrior]

I have a Dart SHP 400 block and Scat forged 4" crank. Darp Pro 1 215 heads. Howards cam, FAST XFI efi. I have an Edelbrock Victor E single plane high rise intake. The exhaust is a set of Schoenfeld headers with 2-3/4" primaries and 3" collectors. The engine is making 5549hp at 6400 rpm and 545lbft of torque. This is in my 1982 Corvette. I have a 4L80E transmission with a 3600 rpm stall converter. The transmission is controlled with a US-Shift TCU. This setup is a real tire ripper.

Your channel is one of the first I ever subscribed too, and due largely in part to the build series you ran on this engine years ago.

[@TheHorsepowerMonster]

Hey thanks! And thanks for watching!

[@vinmandich7756]

You can manage that slip buy installing one of those grip or traction pulleys on the blower I noticed on my 95 mustang it helped with belt slip substantially plus the amount of tension can be dropped on the blower belt tensioner

[@TheHorsepowerMonster]

You are right. Not a bad idea

[@jojog8304]

Yes, vortech offers “high traction” pulleys on their website which have a textured surface. Note the sizes are slightly different (2.93” is a 3”, etc). I didn’t see much different between normal and high traction, but have a much shorter belt in my setup. The belt on that 427 looks way too long that a second pulley is needed.

[@musicfrommicksroom]

After watching those boosted pulls, it's easy to see why the Vortech V2 on my wife's Mustang shreds belts like crazy! I keep several spares in the trunk!

[@teddyjones8027]

Keith is the MAN....

[@TheHorsepowerMonster]

You are correct!

[@stageiimike2145]

Thanks for showing all the mix-ups and screwups, I bet that's how it really goes for most of us. Having to re-do an engine you already paid someone to do once is a real kick in the nads and a big hit to the wallet. Reminds me of when a dyno operator slammed the front-end of my pristine Buick GN into the dyno cooling fans, a 2-day dyno tune turned into a 14 month stay in body shop prison. It has cost me quite a bit to recover the expenses from that fiasco. Everyone I'm sure has similar stories of heartache with their hot rod. Like you I try and do everything myself but sometimes you have to turn it over to what you hope is a pro, in your case an engine builder, in mine a FAST XFI turner.

[@DennisMurphey]

I had build a 1981 Corvette some years back. I bought the car for about $8,000 and it had some miles but was in good shape. Then i found a rod knocking. I picked up a late 80s TPIS engine and had it good over, new cam and valve train, Vortech SC and Headers, then a 3.36 gear with a 700R4 Tranny. I added a boost gauge on the A Pillar and the whistle of the blower and that gage were the only clues. My License plate was C3SLPR and it was a Mustang Eater! I miss that thing. It was so clean and unassuming until lit it up and it would fry the tires and the clutch in 2nd would smell !!!!!!

Pretty sure the Engine belt could be routed wrong and probably needed to wrap around the crank pulley in a different configuration. Hence the longer belt, but I could be totally wrong. Just a thought

Big cube Small Blocks , have no issue with a bigger duration. 252/263 @50 in mine and it idles and drives perfectly

This. This cam is falling off by 6000. It needs more cam, you should be able to make 600 NA with the heads and displacement that you have. Absolute minimum 230 degrees at .050. With 427 cubes the idle will be a lot more reasonable than it would be on a 350.

I'm surprised you would even consider an Si trim blower on that motor. A Ti trim would be my absolute minimum choice with a Ysi being my prefered option even on a street combo. Also, you may look into fitting a spring loaded belt tensioner onto the bracket to help with belt slip. I ran a YSi up to about 18 psi with a 10 rib belt on an old 383 LT1 before slip became an issue. The car made 800 whp back in the early 2000's.

[@ss0073]

Agreed! Running a 10 rib with a spring loaded tensioner with a ProCharger. Making 16 PSI with no belt slip and 817 WHP on a 400sbc. Brodix aluminum block and these same DS225 heads

[@markcollard9326]

Do extra thick head gaskets, 0.040" thicker than stock, throw off the rest of the mating surfaces geometry, mainly the intake to heads angle? I only ask because I was told it does, but this video glossed over it like it is no problem.

[@TheHorsepowerMonster]

A little bit. The intake to cylinder head bolt holes were OK, but where I noticed it most was the blower bracket that bolted to both the block and the side of the cylinder head. It was a little tight, so you had to start all the bolts loose and then tighten.

[@RonaldReed-ul9du]

Hey buddy, If you can get the tension pulley up close to the blower pulley that may do it for no worse than it was. By moving it up closer, and you could also go with a slightly smaller in diameter and get it right up in close. The closer the tension pulley is, the more surface of the belt is on the pulley, for maximum pull power, the belt needs to bite on as much surface as possible! I'd bet it will make that go away except for certain factors. Are you at altitude? If so the blower isn't working very hard, the air is thin, down here at seal level where I live, the air is thick plus it's humid as hell, it'd be more apt to slip.

Can the belt slippage be mitigated with more belt deflection? This is assuming it's worth it and you'd want to machine something else to force it to work...

[@ThePaulv12]

Yeah I'm hearin' ya - there's always something that is NQR. Why can't they sort this stuff out? You know the moment I saw that long unsupported section of belt on the non drive side I thought this is going to be trouble. Granted I am a mechanic so I tend to notice things I know are likely to be problematic, but this sort of thing is disappointing I reckon because it is so time consuming to rectify. Considering the effort they have in the belt and drive not to mention the price of the kit, why can't they just do it right once instead of leaving it to the consumer to grumble? It's not good for their reputation, the consumer gets annoyed - it's all just so, well, um, I don't know, unnecessary. I'd happily sacrifice 15hp if the belt didn't whip like this. It's not good enough!
