Looking for Engine Development Partner

Yes i got a new set of carrillo rods also so they probably have all the designs that you need also.

Any ideas in Cam development ? Is there anything out there now ? What would be considered a "DROP-IN" vs "RACE"

 

[mngforce]

I've seen nothing out there, which is why I plan to develop a cam. I am just waiting to get a full cylinder head with cams to get on the flow bench and cam test stand (like a Cam Dr.).

Web has cams for the gen 2. Not a fan of welded lobes though. I got 2 cams now with severe pitting where the weld is coming apart.☹

We've used the Megacycle cams with welded lobes for years with no issues. The drop in cams added a sum total of 3 hp I think. You need modified pistons and other work to get an real gains with any cam changes.

Sean, 3hp for how much $$$$? Sounds like a little nitrous would be a lot more cost effective.

I’m with you. I want a lot more gains for that money.

Sean. The problem with Megacycle that I have seen is they use a small selection of cam masters. So, hard to get the gains for engines of various configurations. Usually, cams get you that last bit of power in a race application. A street bike with no bump in compression could even lose power if the cam's duration is long enough.

I will work on something that hopefully works for both

A few configurations were tried with specs given to them. Just not much to gain with stock pistons and heads. It's going to need a combination of parts in order to get what you want.

 

[mngforce]

With lower compression you need a faster cam (shorter duration) with higher lift. One that stays at the cam demand during the piston max velocity as long as possible, but closes soon enough to build dynamic compression (compression from IVC close to TDC).

So, yeah, to get power gains, you gotta get the pulse waves right.

Any luck locating a good set of heads to get started ?

 

[user 74794]

Im sending my heads. They have big ports and dinky valves. My prediction they will need bigger valves for sure.

Or smaller ports for Normally Aspirated

I will start a head development thread once I get started to show everything I’m finding. Should be fun.

Am i reading this right, stock lift cams are .350 and the drop-in cams are .360 ? Same duration ?

No i got about .320" when i measured

 

[mngforce]

I will be measuring the stock cams on my precision cam stand

 

[ZX1441r]

Is that the stock lift ? Just saw a engine on Ebay for 5K, is that a reasonable price. 2020 with less then 2K miles ?

 

[user 74794]

Yes both stock cams intake and exhaust were the same lift.

That sounds reasonable. I don't have $5k for an engine for my project. I would rather donate $5k in labor on donated stuff
