help building high revving NA engine.

[illuminarias]

Hi, I'm planning on building a high revving (9k or more) NA machine. I know there are forged CP pistons for campro, but are there forced conrods and crank , race bearing and stiffer valve springs (I'm assuming I'd need this if I rev high? ) for campro?

If anyone has any other recommendation please share. No I don't want an engine swap and no I don't want forced induction.

Money shouldn't be an issue here.

For Campro, most forged internals have to be custom made and shipped it over.
If not Proton R3 can probably help you.
But campro, not even R3 is revving till 9000rpm.
I forgot the post about R3's Campro with 180hp If im not wrong. I can't find the video with the spec now.

Money isn't an issue then go ahead.

Oh? I thought 9K was possible if I did a full balancing?

I am not sure. But I haven't heard of it lah. I could be wrong.

send your car to prodrag, show your stack of cash on their table, say u want a high revving 9k rpm machine then chow.

With $$$ sure able to do it, however the engine configuration will need to be changed as old engine max power is at lower rpm.

But why chow, stay and learn mah!......hahhahhahaha

I think campro design itself cannot wo.

Mod mah! Change / mod until don't follow their design dy....

If money is no issue, you should try getting a quote from the R3 boffins first. Those guys know what they are doing and if given a free reign with the budget, they do a damn good job of whatever it is they need to do. The main reason why I like R3 is because of their doctor-ish clinical treatment of their cars, not like those mechanics whose workshops are dirtier than a junkyard.

And more importantly R3 are Proton experts. If you are worried about what the Campro can and cannot do, they will more than likely be able to tell you.

if you do get it done... revving up to 9K...please share with us the outcome of the project...thanks in advance...and good luck bro

full balancing is a must....

use stock crank..but must do metal treatment (harden+surface mirror polish)

use stock conrod...

conrod and main bearings must be checked and replaced with better option like acl/king race bearings if needed

forged piston but high compression and lightweight...

then do full balancing with pistons,rod,flywheel and clutch assy+crank pulley as whole unit....


that was just bottom preparation..

then must find a way to do custom big flow oilpump...


then must do head port+bigger valve job

then must do custom camshaft..depend on your compression ration decision...might need minimum 285degree valve duration with 9mm-11mm lift camshaft spec..

custom intake manifold... (probably using eagle/edelbrock vtec intake as reference)

custom exhaust manifold (tonnka would be a great choice for that purpose)


then only u need to worry about the controlling brain...an haltech sprint500 is a good option..but meqasquirt ecu also packed with a lot more function....


then only u need to worry about ratio....a bigger final drive would be nice to play...since the powerband also moves up higher in the rev range...

I think campro design itself cannot wo.

campro engine is quite ok for high revving nature due to almost square engine configuration the the 1.3 version....for 1.6 is over-stroke...but i think still can manage to get it rev high efficiently..

 

[DanzEterna]

but so far I haven't heard of campro revving up to 9k rpm,
the only way is to plonk in b16a/b/c engine with fully loaded parts, then use the campro engine cover to cover to vtec head haha

You forgot the crankshaft. Campro crankshaft has a flaw. It breaks at the crank there because of launches. For 9000rpm somemore, I think need to change.

Yeah. I know Campro has a high revving nature.

I thought high rev better if short stroke engine. If over stroke already high rev not that good, right?

quite true...but not entirely impossible....

like the 4age and 7age build up....

Yeah. I know Campro has a high revving nature.

yep..thats why need to strip all and rebuilding it back with better dynamic balancing and better conrods,bearings as well....

They would do customers car? I thought they only did their own R3 racing cars..

Thank you very much. That has really helped me a lot. I kind of know what to do now.

I was thinking of megasquirt but haven't really seen anyone running mega on a campro. Plus isn't it more prone to overheating ?

megasquirt is quite good..bang for buck ecu....

cooling part surely need upgrades too

They do customers cars if you have the money to afford them.
