MBWorld group buy would get the price down I’d think?

Ya to me 3500 - 4k no brainer, 6k just not worth it to me, 5k probably still not unless they made a lot of power. I can get the stock cams for 2k for the set, so that leaves 4k which is half way to a supercharger that gives you much more bang for the buck. 6k is almost competing with a blower and the gains are small comparatively.

It will,i will have something set up

Hard to sell at that i agree maybe 5-7 years ago but these cars have deprecated so much atm
under 4k they will move extremely well imo

Pricing is one thing, but tuning is another road bump if the end user isn’t going to datalog and expect and off the shelf tune to work correctly...


These videos are confusing. So a completely stock car with these cams and tuning makes 425 whp... be nice if they released the cam specs.

BLKROKT

I think buried in one of the videos - there are too many for me to keep track of anymore - the cams made 45whp.

PeterA90

just trying to understand because the video he just posted 4 hours ago said towards the end it made 425 whp... all these video with transmission updates are annoying...

I was looking into cams from the company that made MHP’s and DIME racing... They gave me all the specs on their cams

A set of our Billet Steel cams for the M-156, is $4,400.00 + Shipping


Here's the 2 options I would look at.


H68475-67440: Intake 228@.050" with .475" Lobe Lift. Exhaust 224@.050" with .440" lobe Lift.


H69475-68475: Intake 232@.050" with .475" Lobe Lift. Exhaust 229@.050" with .475" lobe Lift.


We have gone as big as 255@.050" with .500" lift, but I think that required a lot of other changes to the engine.


From what I'm told, they're drop-in, but I would check to make sure the springs can handle the .475" lift. I don't really trust the guys that I was working with. They never gave me any power numbers, but they seem to like the second option better for the Normally Aspirated engines.

you can the lift on these are way more aggressive than stock. Just no real world feedback since dime wanted 8k+

deadlyvt

if you do that would be nice closer to $4 grand I think we could get some buyers

BLKROKT

At 4 grand they’ll probably get 10-15 pre-orders just from here. I know I would be one.

At 5? Mehhhhhh...

Any updated word on these?

BLKROKT

Can you believe this thread was started over a year ago already

Was there ever an update?

roadkillrob

Last I saw he put them in a car and did a dyno and then this was the last update in December where he was getting new ones made with different specs and was going to be a month or 2 to get them made.

hachiroku

basically a drop in stage 1 cam...

a proper camshaft should require remapping of valve timing to maximize efficiency. with this in mind, he'll be limited on lift and duration of the camshaft if following the same intake and exhaust timing mappings.

go team

Yeah Im curious now. He wants it to be bolt on ready but also make power, which will still require tuning (probably custom). So not quite drop in and go.

yfz rock

any video or dyno numbers of you’re cams running?

djr48312

What was the powerband on each of the cams? Why not .550" or .600" of lift?

sickSVT

You'll most likely have to upgrade the valve springs and other internals to support a large amount of lift making it more expensive.

The springs bottom out

That's understandable. Springs, and retainers, perhaps the shims under the spring. I saw a lift test on the stock springs SLS and C63. Intake lifts to 12mm and exhaust lifts to 11mm. The exhaust had plenty of clearance at it's max lift. The intake had several mm available before the coils collided, maybe 3 or 4mm.

djr48312

Also for the .550" or .600" lift one will need to do clearance on the head for the camshaft to rotate. CNC Heads provides this service for a few hundred. Just something worth looking at.

swedepat

You can make the basecircle smaller to make room for more lift.
But it needs lashcaps or longer valves.

djr48312

No issue with longer valves. How much additional lift can we obtain going to a smaller base circle on the stock cam cores? Does anyone know if the valve reliefs are the same on the C63, SLS vs Weistec and other pistons?
