What cam is this? Suggestions for replacement?

[Oneofthegreats]

Just letting you know Pete.

From what I've read, BBM are more of just supplier/distributor. There own product's are sceptical & over priced IMHO!

Eg. The cam's spec's are the same as TT (Techtonics Tuning) cam's right down to the TT part #'s & are more than likely the same cam's.

8V are good for street and general use, but you can get so much more power out of a 16V, it's almost not funny.

Just out of interest sake.

It's actually been very well documented that it's easier to gain NA power out of a 8V on a cost vs power ratio due to the 16V poor cyl head design, which has been regarded as the worst designed VW cyl. head 2nd behind the VR6.

I've only read this & haven't done it, but they say it's also easier to extract double the output of an 8V vs 16V NA tuned.

In saying that though, if I had some spare coin for a nice daily driver, I personally wouldn't mind building a simple 2L 16V setup with Microtech LT8, EFI Hardware 45mm throttle bodies (The Badger5 complete 16V setup is £2350.00 GBP http://www.badger5.co.uk/ ), CR 10.9:1, cleaned up port's, TT 276° cams, 4-1 extractor's & 2.5" full flowing system.
Should make easily 200+hp properly tuned & be reasonable on the go juice.

But for less money, I could also throw a turbo on the 8V & make the same HP easier & with a ton more torque, which I reckon would be much more fun!

6 of one, half a dozen of the other. Your choice.

Yea, I agree Tim.

Although I know nothing about the head designs, just from driving my 1.6 in the Golf, it was a much easier engine to drive, (and thrash) than my 1.6 16V (in the laser)

Sure the 8V was modified slightly, but the 16V you really have to ring it's neck to get power out of it, where as the natural tourqey-ness of the 8V makes it a much more streetable engine IMO.

Having said that. If I were to spend some dosh on a "race" engine, I would go a 2L 16V for sure. A nice set of cams, and well pretty much all the work the Preen is doing to his engine, I'd do if I was building a full blown Race engine. hence my recommendation to Pete.

Sure an 8V can get good power, more so with a turbo (duh) but a turbo on a 16V, would be exponentionally beneficial.

OF course it comes down to money. 8V has half the cams and valves, so it's already a bit cheaper. but money now object (or less of an object) a 16V for it's tunability.

Having said all that. I'm pretty sure I've just reapeated what you've said Tim, but just using different words! hahah oh well.

Beau and I were talking about this last weekend. A crazy 8v is quicker and more reliable than all but the most extreme 16v.

Also consider the american aba crossflow heads they can make stupid power from an 8v and can run kjet

[GoLfMan]

i think i'd be more inclined to build myself a pretty crazy 2L 8v twins, big valve head, serious porting and all the exhaust hizzle dizzle for racing.

Torque wins races

[twin eng, twin turbs]

A couple of more questions,

How big are the valves in the "Big Valve" 8v head?

What is the spec of the G Grind cam? 268 degrees?

Any links or websites I should read?

I'll drop the head off this week and see what the go is.

Pete

The valves in your head are 38mm inlet and 33mm exhaust. If you are interested i have a fully ported and polished head identical to yours with extensive porting and polishing, new valves 38mm x 33mm, guides and seals. It has had 0.08mm machinced off the deck and the combustion chambers cc'd, polished and matched. Its perfect for a street car and is surplus to my needs so i will be selling it. pm me if your interested

I've thought about getting one from the US, already worked, and putting it on twins probably. But then again, I don't really have money for it, so I'll have to stick to GX's and so on an so forth... Oh well.I'll live.

Golfworx, stop stealing my cams ideas!

Jarred, stop stealing everything else!!

Really its 8v for street, but if you want something with serious poke for competition, 16vs are the deal.

The 16v head is actually quite a good head. According to a guy from Greece named Spyros (oh its getting worse and worse here isn't it? haha) who is building a 1000hp (yeah thats three zeros) 2.1L 16v, he chose the VW 16v over a cosworth BDA or BDG because they have a better head and flow better.

This is very true.

I've seen build up thread's on Vortex about ABA 8V's making some very nice hp & torque numbers both NA & turbo'd.

This is turning out to be one of the best thread's in a while.

[Jarred]

.... who is building a 1000hp (yeah thats three zeros) 2.1L 16v, ....

firstly.Spyros. hahaha

secondly !!!

I'm geussing this is turbo'd and must have some serious work done to it!

Got a link by anychance?

links to these threads mate? and whats the availabilities of these heads?

just look on vortex, I've see a fair few threads with guys with ABAs on megasquirt and etc, but due to the quantity of threads on vortex, you might have to do a bit of searching.

From what I gather, ABA's are reasonably common in the US, but just shipping, and finding *just* a head that someone would be willing to send out, wouldn't make it worth while IMO.

For the money spent buying it, and getting it shipped over (due to it's weight) I think i'd be more economical monetarily, to spend the money on a head available here, and get more work done to it. If that makes sense at all.

Then again, I'm just spit balling here

[GoLfMan]

GROUP BUY
if we shipped bulk itd be sweet...
im just keen on the idea of not having the inlet over the exhaust so i dont get heat soak in my DCOE

DOH!!!

Sorry Preen. I totally forgot about that .
If I was going 11.0:1 CR on a semi race engine, I'd go bigger cams, but for most people if it's a purely street engine on PULP & maybe ULP, 276's would be very nice.

Although saying that, the people that know me from my past I would go bigger cause I love the rough idle & run a bigger stall.
My old every day'r ute had a 3000rpm stall.

I've read of a 1000+hp 16VT that split in half

now thats a break up that cost more than a divorce
