SOHC Turbo Cam From Blank?

[Edub1]

I'm wondering how cost effective it would be to get a shop to grind a bunch of turbo cams from blanks. This would avoid the solid lifter conversion or milling of cam towers.

Perhaps if we could get a group buy going and do like 20 it would be worthwhile.

Either that or I was just considering a performance N/A cam and call it good enough.

Comments?

I would call around, and in your area, I think it would be most affordable. But I think that someone without much knowledge of the KA setup will spend a lot of your money on the learning curve, you may just be better off getting colt cams or PDM racing.

You'll probably end up spending $1000 of your own labor plus the uncertainty of it not working properly. I've learned to just go with whats out there and concentrate on other things in life.

That's actually what I had in mind as they already have the specs. I don't know why they don't do these from blanks but if a guy ordered 12 of them they just might.

Do you have problems with the regrind, or do you mean having Colt make it for you? There is not a lot of mystery in cam design, it is just a matter of trade-offs, but you can spend some serious time fine tuning where you want to make that trade off. You are very ambitious with some of your ideas, but I don't feel that you should pursue this, it will not be cost-effective.

I'm just talking about getting a bunch of guys together to persuade colt or someone to put a turbo grind on some blanks rather than a regrind. I'm not going to try to design the thing myself.

Trouble is, us SOHC guys don't have adjustable lifters and that is another $300.

Besides I'm sure many shops could look at the stock cam and shoot out a custom gring no sweat.

I don't know, but you seem interested, and I am subscribed. So I am interested to see what you find out. I am DOHC, but you can call it curiousity

I am also intrested in this. im a SOHC guy and recently started looking at cams, and came across the Colt ones, like everyone else has, and it says you have to mill the towers so it will fit. I would most certainly prefer a drop in replacement so I wouldnt have to have that other work done.

[Chezedik]

Well, if you have to mill the towers, it proves that they are using blanks, since they operate on a larger base.

haha oh. I dont know anything about cams, i know the purpose they serve but thats about it. I was just restating what I read on PDM's website.

I had a set of "custom" cams built for my Skyline to my specs. I sent them a set for regrinds though. A regrind is essential in the cam design process unless you are willing to do a **** ton of math or pay someone do design it for you. I went through Integral Cams. HERE is their price list and explanation for a complete custom set.

I had them do a set of regrinds to my specs, which I basically copied from HKS and changed a little to suit my power band. IIRC it was only $350 for the set. But you have to email them to find out for sure. Great customer service and an excellent product.

Sweet, so all we have to do is get the cam specs and put together a group by. But, I wonder if there would be that much of an advantage over just going with an NA performance cam. By the way, what is IIRC?

[WDRacing]

Well if you want to do a group buy, you need to let me know first. All GB's on Nico have to approved by Greg becuase we've had issues with fraud etc. Its just one of those things. I doubt there will be an issue with this particular GB as its simply a purchase from Integral. In fact since its done through Nico we may even be able to get a further discount.

IIRC = If I Remember Correctly

One of the issues with SOHC thats sucks is no adjustable cam gears. SO with alot of duration and lift increase, you don't have the ability to advance/retard the cams to get the full benefit of Lobe Seperation.

I have no diea how much the NA cams are so. Can you post up the stock vs aftermarket specs and price?
