TRD cams max RPM

[The Big Yin]

I am selling a set of TRD CAMS on ebay at the minute I had planned on using them in a 11k rpm 200bhp engine

Now I have just received a question asking what the max RPM for the cams would be

do you think it would be about the 11krpm range

Intake 312 duration. 11 lift
Exhaust 304 duration 11 lift


probably going to say 11krpm as that is what i pourchased them for

[YGT04A]

what motor are they for?

[The Big Yin]

opps sorry 16v 4age
was planning on building a screamer of an engine

[stan]

How much do you want for them posted to tassie 7000..
Cheers..

[The Big Yin]

will need to check shipping from the UK Tasmania lol

[The Big Yin]

1,040.16 AUD is what it comes to converted from £


shipping would be 145.572 AUD but I would meet half way with that

mods please note i did not intend this to turn into a for sale thread

[oldcorollas]

11k? errr... maybe not... more liek 8-9K

11k is more like 320deg or so.... and it is unlikely that you will peak power at 11Krpm anyway.....

you can say 11K, but it's a bit of a tug



unless we are just talking free-revving when you hold your foot down? in that case it will depend mostly on the valve springs

[jeffro ra28]

agreee'd 11k is a tug.

Id say 8500-9000

[oldeskewltoy]

Hmmmmmmm, well... although cams ARE different... there isn't that much different....

HKS cams (their current crop) has rpm maxs of 8000 = 256, 8300 = 264. and 8800 = 272. I believe I got my copies of the HKS cam cards here

Based on that(HKS cams).... I'd say 312/304 is more than enough for 10k! ( with the PROPER management!!!)

jmho........

*IF*
256 = 8000
264 = 8300
272 = 8800
280 = ????
288 = ????
296 = ????
304 = 10k???

As I said above... properly tuned 10k+

[jeffro ra28]

no doubt it will rev there, but will it sustain power there?
Maybe we should be talking RPM range, rather then max rpm

[oldcorollas]

to reach an rpm while free-revving the engine only needs to make enough power to overcome friction.. and that the valves not float...

so in that respect, with the rigth springs, it will rev TO 11K... but i am sure that is not what the buyer wnts to know...

ah, apparently the FA are 320intake, 304 exhaust, and they are rev limited to 10800 (and need around 9000 to get into power band) (but don't make peak power there)
but on a less developed motor, you will not peak that high at all.

edit: mayeb it is more truthful to say "i bought them for an 11K build, but i have not tested these cams and don7t know what the max rpm or peak power rpm would be"


and 200hp at 11K? thats 20% down on power from an FA motor.

[takai]

OC is right, ive had an old Daihatsu 600cc engine at 10krpm before... just before it died.

Probably wasnt making any power at all, but it was revving that high.

Cf with my race engine which is still pulling at 9000rpm, but with much larger cams. It wont make 10krpm i would say because the valve springs would float too much.

[The Big Yin]

when doing a little research before buying them a few people had used similar lift and duration CAMS for the power I was looking for, and about the same rev range as well,

but perhaps I was wrong, when doing the research these lift and duration cams were definately the ones i wanted for 200bhp, but perhaps not the RPM, I had planned on doing the build properly the whole shebang not just throw the cams in

I know that i just a little down on a FA engine as well

[oldcorollas]

fair enough... i would've thought 20% down in power would at least mean 15% down in rpm = abotu 9000rpm

fwiw, you can get a brand new 11mm 304 for $420 http://page.auctions.yahoo.co.jp/jp/auction/107168824

and new set of In+Ex of 10+mm (ie, 10 or 11mm) for $720

then again, stufff usually costs more in pounds than in dollars and yen (i hate to think what you pay for beer.. water is expensive enough )

i think the wording of your ad is not misleading


(edit: i was meaning, those cams for that power at that rpm = a poorly built motor)

[The Big Yin]

Yeah we pay a lot more for stuff than pretty much anywhere else in the world. So that means buying stuff from america aus and japan is much cheaper for us. But makes it harder to sell stuff to.

It is also my understanding that the cams are no longer available.

Yeah it was not going to be put the cams in and hope. It would have been a full bore build
But decided to go turbo power i think
