Thoughts? Cam combos?

Any thoughts on the kit above?

Also any thoughts on desired cam profiles?

Would be in a stock 1600 EFI.

Looking for power off idle to 6000 ish.

AJ is one of the kings of making good VW heads. Only problem I really ever had with him is, on his products, he doesn't tell you a damn thing! No information on the cam, no flow numbers on the heads...I guess you just have to take his word for it.
Are you dead set on keeping yours a 1600? I think a cool combo would be some cnc panchitos, a web 218 cam, and a machine in/slip in 88mm piston and barrels. Unshrouding the valves in the heads by going to a 90.5/92mm bore has to help a ton.

It’s gonna stay a 1600 for the next 5-7 years.

I’d like to up size injectors and finish my compound turbo set up and try and run 40 psi or so.

But I would like to make the 1600 as good as I can for the time being.

[buguy]

I understand. I'm interested to see what you come up with. It's super hard to decide on stuff when your making big boost. Just really isn't much info out there on doing all this to a 1600.

I wish I had a few of them so called turbo cam in stock just to compare to the N/a cams I've talked/ B.S.'ed with a few old time turbo guys aka. years of turbo knowledge) and a more then a few told me if u like a certain n/a cam ,,it will work with force induction , one of the fastest told me he don't go for the 112 lobe deal, but likes ever a 105 If I had Buguys mouse motor I'd swap out the the tc20 to a w110,betting drivability will be back. the only way I'd deal with A.J. in i lived right down the street from him,, do your research,,
for a 1600-1915cc I'd like to try fk-8 just use 1:25 rockers on the Mouse

I don't have a TCS20. I have a Web 163. It's 422 lift and 250 duration @ 50. It's right between a 110 and a 120. But I agree. Something around a 235 to 240 duration cam would have been better for me. A 112 lobe is just a more broad powerband. I thought with a 112 lobe and advancing the cam I could get away with more duration for more rpm. And I don't want to make it sound like it doesn't work because it does. But for my driving style and location it's just a bit much. I liked the instaboost better.
That said, I waxed a new WRX the other day. I didn't know the guy so I don't know a thing about it. It was from a roll and I was at maybe 2000 rpm in second. I slipped the clutch and it boosted hard right off the get go. Pulled away in second, he came around me when I shifted (remember I spun my 3/4 hubs so slow shifting) but once in third boost came on hard and I left him in my dust. Let off around 85 mph. When my boost comes on it compounds super fast and the pull is unreal. Where it sucks is cruising at say 40 mph in third gear and get into. Bit lazy there.

Ya ,,in your area and driving style you definitely don't need a wider/broader power band You Mentioned in Villi's tread/post "it just takes more RPM's " sez to me wrong cam , our cams in the 'perfect world':1200-5000 or 6000 rpm max torque & H.P. and slippin that clutch disc ,,will be a ticking time bomb,sooner then later it will start slipping
I like just stomping on the loud/load pedal and off u go,, no hiccup ,just haulinass, if the tires hold

[buguy]

Yes your right about the cam. I was just chasing more HP. The easiest way to make more hp is to spin it more. Didn't really work out for me.
I also agree about the clutch. I was probably going around 10-12 mph at the time and it was lugging. Had to do what I had to do!
Fun part was that since my gears are so low and and jacked up, I really had never felt boost right off the start like that. It was actually pulling so hard it was pulling my foot off the clutch and I was having trouble modulating it. Super fun. I remember seeing 26 psi (hard to watch that and the road!) and it couldn't have been at maybe 1800 rpm!

[Schweg]

So with all of the above factored in, is the general consensus that a good driving street cam is what you want for street vs having a turbo specific cam?


Looking for boost (5-7 lbs) at 1500-1700.

Thanks

[buguy]

You will most likely want a small cam little overlap if you want to build boost that quickly. I have a small turbo (not as small as that 9b though) and even with a stock cam and 1 3/8" header I wasn't making boost that quickly. 2200 rpm was about as soon as I was making boost. I will take a look at my logs to be sure though. The small cam will mean it will be over at lower rpms too though. Really depends on what your after. At 1500-1700 rpm boost, you would be boosting pretty much all the time!
What rpm do you make boost now?

[Schweg]

I have a 13t. I’m in boost at 2200 ish as well, but I’m not seeing the pull or the numbers I would like to see till redline.

[buguy]

Hummm. Better find some E85! Ooooor! I dont remember if you had water/meth Injection or not, but that along with a nice shot of nitrous would do the trick!
The other day I changed my timing to 40 degrees at around 3500 rpm and did a smooth. It probably changed it maybe 1-2 degrees most everywhere else and it helped me build boost faster. Without E85 I would never do that though. In fact it makes me nervous with E85!
Although I think retarded timing is supposed to build boost better?! Fun huh?!

I have water meth. I’ll pass on nitrous the compound set up should be swap able so I’ll run the 13t and 9b for around town and instant boost. Then I have the WH1C for big power.

a 40 x 35.5 valved head will help big time If buguy had them that web cam would work better

[buguy]

Definitely! I talked to Dave Kawell about it a while back and he told me some 40x35 valve heads and having at least a 90.5/92mm bore would help a lot. Said that a bigger bore head unshrouds the valves and really let's it flow well.
Unfortunately for me, I just don't think I could bring myself to spend anymore on this engine. It's service life is over. I've had my finger on the trigger many times on some bigger/better heads though.
