How to get a 7500 rpm red line

[Yo Vic]

OK, my motor now has 115K and a new garage all my own. I love high rpm revving motors. Any engine subject matter expert out there know what it would take to achieve this goak? The controlling variables I can think of so far are: Cam profile, extra oil gallies to the crank (if even possible), synthetic oil, solid lifters vs. hydraulic (if needed), bearing material in all locations affected by the higher rpms, increased fuel rate, larger injectors, larger volume of air taken in, transmission improvements, driveshaft balancing.

What am I missing. Anyone with experience want to comment?

Thanks!

I'll second this question, I was thinking about asking something very similar myself. Especially with the 4v motors, they tend to make power as they rev higher, which leads me to a question on the subject myself: how much power would be yielded by revving up to the 7500-8000rpm range? I think this would be an awesome build plan for staying N/A.

Cams prevent the engines from revving higher.
Valve springs may need to be upgraded to prevent valve float at the higher RPMs.
Solid lifters and double-roller followers from Jesel may help too.
If the cams were changed, the rods and pistons will still be a weak link.

I believe the stock TC may be an issue at higher rpms also. I do not know what the aftermarket ones are rated for either, but they are better off then the stockers. I would recommend an electric water pump also.
In general, it's a lot of money for little gain to get to 7500 rpms. Your motor life will be decreased running at those rpm's frequently also. But if you are already considering refreshing the top end, go for it.
Sean Highland's book discusses it IIRC. Talk to some of the companies that build racing mod motors.

03/04 Mach 1 motors out of a manual model can do about 7K rpm.

Hey Brian! What is the highest cam lift we can safely get with an uncut flatop piston? We don't want overlap and too long a duration if going sc too, right?

Not sure about lift vs piston clearance, I have dished pistons myself.

.495" lift is spec'd on some aftermarket cams, no mention of piston interference but the valve springs have to be changed.

Overlap can generally be adjusted by re-indexing the cams, most of the upgraded cams have a pretty long duration though.

I heard tell that the trans can't do more than 7K :depress:

Not sure about that, I believe it can but the PCM is too busy to run the engine and trans both at that RPM so it causes over-revving and missed shifts. May require a standalone transmission controller similar to what I'm using. I have a PCS controller, the other big name in that business is the Baumannator.

Ahh I could see that. I've tossed around the idea of serious revs but it looks like If I do anything else or even hook I'm gonna need a cage, so I guess I'm done with mods :(

We need to work out a bolt-in 5-point roll bar. That would be good for 10 flat.
