New Dinan pulley and belt system for V1 Blower

[seoulman]

I recently had my car undergo about a 3500.00 maintenance job...inspection II, new brake pads, rotors, starter, etc. I know a number of things could have been done on my own to save costs, but I just dont have the time.

Anyway, for those of you who still have your Vortech 1 blower with original belts, you will have to upgrade to the newer Dinan vortech pulley kit (D865-0100) and belts. The original belts are no longer available.

I've had the original belts for about 40k miles. Not that bad considering that i've tracked and auto-xed the car a number of times.

Parts/labor cost about 600-700. Im pretty disappointed that dinan didnt offer the upgrade for free, considering that I had no other option. It's one thing if I can use the same style belt, but to be forced to upgrade to a newer system and have to pay for it...that kind of sucks, but im not surprised.

Just something dinan sc owners should know about.

What and What? Something doesnt sound kosher here. First, who says you have to source your belt from Dinan? When I went with a 1" larger pulley, we just got hold of a few Gates and Kelly springfield 6 rib belts in various circumfrence sizes around what we thought we needed. We found the one that gave the best fit, returned the rest, and bought a spare...Cost was around $20 ea if I recall. Am I missing something here? I cant imagine had I been looking for a belt for the out of the box Dinan system with 5" crank pulley, it would have been any more difficult than this. Whats the catch?

Don't know if it's easy to find an aftermarket replacement or not, but I can confirm that Dinan is saying this. I had an early Dinan pulley set, had the belt replaced and the replacement belt was too long, causing the idler tension pulley to move over so much that the belt was almost rubbing against another part of the belt. Their solution is to upgrade to newer pulley parts. BTW, I believe I was the first to discover this problem last year. Their techs didn't notice the issue till I brought back the car the next day.

Cmon guys, just take your old belt, or its measurements to your freindly autoparts store....Dinan doesnt have a monopoly on belts! I suppose its possible that the company Dinan sources their belt from like Gates or KS or others have stopped making the stock size....But I can tell you I had NO trouble getting belts for the 1" larger crank pulley and my stock Dinan SC pulley...As a matter of fact I got both a Gates AND a KS in this size!

OMG!! That is THE biggest scam!!!
$6-700..? OK $20 maybe, but how can you let your dollars just fly out of your wallet like that?:cashwalle

Part of coming to this site, is to ask questions before spending astronomical amounts of money.

$3500!!!! What did they do give you a new tranny?
Please let us know what they did, and what dealer is doing this to you.

Please ask us before you set yourself back like that...:az:

[seoulman]

I know...I know...I dished out a lot of money!

My car was really running like crap, so I took it to the same place that installed my blower and had them do a complete inspection front to back.

As far as the belts, yes, that's what I was charged. The parts alone were about 3-350 and the rest was labor. Actually the entire job was practically labor charges. The fact that the shop is strictly a dinan dealer, etc...didnt really help in terms of price, but, I know the mechanic well and he is very very good.

Also, I know that I could have saved my self a few hundred by doing it on my own, but as I said before, I have absolutely no time. I work 7 days a week!!!!! I have my own biz, so it's tough to get some time off.

Ok, as far as what was done...here goes.....

Full inspection II service, new airfilter, new erk for SS, new rear brake pads, rotors, sensor, new guibo coupling, new rear shock dust sleeves and bump stops, new front inner fenders, new dinan pulley system and belts, new starter, new power steering hoses and clamps and radiator flush.

Parts came out to around 1700 and the rest....labor charges.

I was having so many small problems with the car, but now, it runs like new....as it should....after spending that much money.

Oh well.....
:dunno

26lb Injectors

Seoulman, just curious, where did you find out your injectors, which i assume you got in your Dinan kit, were 26 pounders?

[seoulman]

Paul,

I believe that's what I was told when I had the blower installed. I also think it was on Dinan's Site a long time ago...but I could be wrong.


I recall you saying that you had 28lb injectors?

[paul e]

I recall you saying that you had 28lb injectors?

I dont know why Dinan makes it such a damn mystery...Like they consider it proprietary information or something. Could you imagine buying a fancy CD player, or a receiver, and when asking the vendor whos codec is being used, they tell you 'sorry, cant give that out'....It would be laughable. I think they are near, like within about 5% of 30 lbs, but the exact amount, I dont know. And theyre not talkin'!

[V Shah]

According to this site: http://www.kenne-bell.com/superchargers.asp which I believe got their information from the CARB info itself, they are 28.8lb Lucas injectors.

Hey V Shah, great find on that website! Notice that it also says no bypass valve? Clearly, its only referring to the Powerdyne system...Its true that the powerdyne kits didnt featuer the bypass, and did feature the 28.8 lbers. I know that they introduced the bypass valve with the Vortech kits, and Im just wondering if they increased the injectors at all..I think not, but I was just wondering.

The supercharger uses a 3.03" diameter pulley and a 5.5" diameter crankshaft pulley with a max. boost pressure of 10 psi.

[paul e]

Good find, kit...But why does it say we dont have a compressor bypass valve...Thats just not true.

[ultim3]

My dinan Powerdyne has a Bosche bypass valve. I replaced it with a Go Fast Bits bypass/BOV just to hear it a little though.

Paul is right here.

What has happened at Dinan, is they have decided to not support the older and discontinued products and have capped the products with no more support or inventory.

When that happens the newer Dinan people looking at cross referance manuals see nothing and are fookin clueless?

[cal_guy19]

Hey guys -

The Dinan stage I S/C kit. Does it or doesn't
it have a boost pressure bypass at partial throttle (manifold under vacuum)? If it does, wouldn't that have to be in the CARB paperwork for certification?

[Mitch P.]

The Dinan SC kits for the 328 (powerdyne head unit) did not have a bypass valve. I've seen an M3 with a powerdyne unit that also did not have the bypass valve - both kits were making 6.5psi.

All of the Vortech kits I've seen here in WA do have a bypass valve though - maybe due to the fact that they are producing higher psi.

[paul e]

I will vouch that my Vortech V1 blower kit came with a bypass valve.

[Beau]

Wow, Dinan truly is a sleazy operation. I can't believe they couldn't simply give you the part number for your current belt so you could buy one from any number of brands.

My Dinan Powerdyne kit also came with no bypass... interestingly enough, there are still bungs on the pipes to hook one up though.
Perhaps they kept it off the kit initially so they could engineer a 'magic' one down that only works with Powerdynes on BMW 6s, of course to be offered down the road as a $1k upgrade. - Beau

[Mitch P.]

it is a standard 6-rib belt that you can buy at almost any auto parts store. I can look up the part # if anyone is interested. It is a cheap part.

>>Perhaps they kept it off the kit initially so they could engineer a 'magic' one down that only works with Powerdynes on BMW 6s, of course to be offered down the road as a $1k upgrade<<

LOL... I have to really wonder about them. Anybody who followed their exploits last summer in Bimmer magazine, and saw the hoops they had to jump through just to try and bring an aftercooler to market, would be amazed. The bottom line is, for some reason, they decided to do an air to air aftercooler, instead of air to water, with the result that plumbing headaches were so severe, that theyare the only ones they will let install it on any cars, and they have to be shipped out to Cal. Price is something like 15 grand, if theyll do it at all. mostly, they made it part of the iSR signature vehicle, at a $35grand premium or something like that. Its too ridiculous. They have customers clammering for more boost, so they decide to offer an intercooler to help augment the power bump. ONly they cant find a way to do it to be competitive. Makes me sick. God knows we could use an alternative to the RMS one, but I guess they really ate Dinan's lunch on this one.

[Mitch P.]

just for reference, after I upgraded to the RMS 6" pulley and retaining the 3.125" SC pulley on my Powerdyne setup the serpentine belt is Napa #060480 (1240mm) and costs $25 or so. This belt leaves plenty of distance between the tensioner and the main belt too in case anyone is interested...

[paul e]

Mitch, well, I just learned that for some reason, the kit for your 328 and for the M3s takes different sized belts! Since we have the same crank and sc pulleys, youd have thought wed take the same sized belt. But on mine, I take a belt sized 54". And the stock dinan belt with the smaller crank pulley is 53". Yours is only 48.8"

[Beau]

It's a Powerdyne vs. Vortech difference and how the superchargers are situated to fit in the same space. The Powerdyne's pulley ends up being much closer to the crank. I actually tried to fit my Powerdyne belt on the Vortech and it wasn't even close... like you said, it would have to grow about 4-5". - Beau
