Bro for your CPS is 10w 30 specs la

So, what's wrong? Any oil will do, just get the one that suits you. I prefer a solid feel anyway.

as i know that ur cps system function optimally with 10w 30 oil if the oil 2 thick is hard for lub pressure to actuate the plunger in the hydraulic bucket tappets.

Maybe. Why is it race prep CPS uses 10w60? And did you ever come across SC that got 10W30 in stock? BTW, in my 2nd service, COSE put in 10W50 mineral oil if I remember correctly.

Its the same with using 17" rims when the recommended is 15". But we modders love to test and try.

I'm not so sure about CPS, but if the plunger was operated based on oil pressure, then the 10w50 gives better pressure compare to 10w30. By installing a oil pressure meter u able to see 10w30 drops pretty much when it's hot compare to 10w50.

I'm using 10w40 on my Mivec and 10w30 sometimes give me problem with the mivec engaging point.

Comparing the 'feeling' between 5w50 and 0w40, I prefer the former. But will keep my eyes on the FC.

dats why CPS has a oil cooler to keep the oil in optimal temp,i guess mivec has no oil cooler ,the oil galleries in the cps bucket tappet is quite small so i guess thicker viscosity will affect the cps operation. Trust me bro i have many customers who serviced at branches and then come n complaint that the engine feels sluggish after service. I know many SC dont keep stock of 10w 30.

Weird, not feeling sluggish at all. Anyway, a higher viscocity oil are better for hot climate and engine that always being driven hard ( ). BTW, actually I never been to an SC with 5w15 oil in stock.

1 question whats the max speed can ur CPS push?

195. Even after mods.

Ur's is manual or auto?

his one is manual i can reply that for him hehe

I tought that CPS have capability to push over 200km/h i guess the final drive is slowing u down for higher top speed. Yesterday tested my old aged campro achieved slightly over 200km/h maybe around 208km/h just only mod the headers midbox and mufflers. Wat mods have u done?

Full exhaust, air filter, LCP.

I think the ECU is the one slowing me down. At 4th gear 180km/h@7.2k rpm when shift to fifth, the rpm drop straight to 5.2k and can go up to 5.4k rpm before it refuse to go up even when going downhill. I think all CPS owner has this problem.

ur not revving enough bro CPS rev cut at 7.5 rpm,as i know from proton that specs that all CPS engines are equipped with a new gearbox model actually its the same model that is used in the mivec engines,i cant remember the model code,the final drive ratio is big its designed that way to improve the low end performance likewise my gen2 has a smaller final drive where i experience sluggish low end performance but good high end performance.

My 4th gear max speed is 190km/h its around 6krpm++, when shift to 5th gear need some time to get 200km/h slight downhill can get 210km/h.

Most CPS engines actuate the high lobe cam at 3.8krpm unlike Satria Neo CPS which actuate high lob cam at 4.8krpm.

The rev cut at 7.2k rpm ler bro..

Mivec don't need oil cooler, as the engine in optimum performance when it's hot and that's totally reverse if compare to CPS I guess. In other words, the hotter (of course in between operating temperature) the better for Mivec to engage.

if im not mistaken i drove a gen2 cps rev cut at 7.5krpm i could be wrong.

Added on July 24, 2009, 11:11 pmdin know that bro,actually CPS uses same technology as porsche variocam,so oil viscosity need to be stable when running high temp.

the close ratio GB code is FM542-1 couple with 4.625 FD.

Higher viscosity oil is better at high temp, rite?
