I dont want to be anywhere near that engine if he gets it to 11,000 rpm....

 

if you don't mind replacing your engine every 5000 miles...

You will need to remove your entire engine, and replace it with one of these:




It even has VTEC...

NOTE: Your car will be noticeably slower, but this engine is good up to 33,000rpms!

EDIT: I am not a naysayer, doubting Tom, or trying to ruin the thread. I just thought it was funny when I found this model car engine with a VTEC brand on the side. And...technically this would give him well beyond 11,000rpms so it is an answer to his question!

 

people please do not respond further unless you're going to give him serious answers about his question. number 1, it appears as though english is not his primary language (no offense to the poster) so you guys are doing nothing more than making it harder for him to find the answers he wants. and for those who are saying it can't be done, you're not even being constructive about it by saying WHY you think it can't be done. you're just all laughin and not helping in any way shape or form. so please refrain from posting if you're going to ruin his thread.

for those who are saying it can't be done, you need to learn that nothing is impossible.

the weakness on the F20C when revving beyond 9000rpm is NOT the bottom end. in fact, the bottom end is decently strong. it's the head you need to worry about.

you would likely need new valves, valve springs, retainers, etc. in overrevs on the F20C, the damage is often caused by valve to piston contact since the springs and valves can't keep up with the speed.

and for those who want to be doubting toms without providing any reason why, let me enlighten you.

Here is cjb80, a member on this site, who has a built engine. now he mentions in this post he felt the valve train he had was not only inexpensive, but could handle 10,000rpm no problem. (though he stopped at 9700 due to some noise just to be safe, until they could find out the noise problem)

so he's got an INexpensive drive train that can take 10,000rpm. I imagine with more expensive parts, 11,000 should be attainable.

and that's my proof why it IS possible.

 

the naysayers don't know WTF they are talking about, and feel talking out their ass is a substitute for actual knowledge... Also, am I the only one who noticed this guy is boosting?! 30 hp gain is low for an extended RPM range... please don't waste anyone else's time by posting blatantly WRONG information....


In regards to the question, yes it can be done, and not at any great expense (15k is so laughable I'm not going to bother)... cjb80, a board member on here, developed a dual valve spring system he used on his car and a few others. With these, along with new retainers and seats, you can rev to a MAX of 11k. With an EMS tune (this is assuming your running a full standalone with your turbo setup), reving to about 10-10500 on a daily basis wouldn't kill you... Reving to 11k on a regular basis wouldn't be advisable, but it could be done if safety wasn't your #1 concern and the extra 500rpms was... I'm actually having him instal this setup on my car and taking it to 10-10500k daily... PM him of you are truly interested...


EDIT: Wisconsin, sorry, I didn't thoroughly read your post and saw you mentioned much of what I did already... oh well, you beat me fair and square...

 

I win.

 

Doesn't the Spoon S2000 have a redline of 11000RPM or so? Or is it 12000RPM?

 

Im sorry, but the idiots claiming you can just add some valve springs and retainers and tune it to run 11K RPM is just plain stupid. Your going to use those stock valves and cams and ignition with no headwork and just say hey lets go to 11K today. The head is not going to be able to flow the amounts needed at that RPM. If you were serious about 11K RPM reliably you need to start thinking about things such as destroking, forged pistons and connecting rods and serious headwork. But hey Veilside AP1 im sure has an extensive engine building background and has no problem just telling to throw in some springs and go for it.......?
