I have talked to a couple of people and they say it is safe to run ctr cams in a gsr and be able to rev to 8 grand without the possibility of valve float. Is this true? Can I rev to 8 grand with the ctr's and be just as safe as if I were using the stock cams? Thanks for your help.

um nope... the valvesprings of the stock engine are not hard enough to hold the cams in place... you can rev to 8 grand all day on a gsr anyways you shmuck its 9500 you wont get to

well not with those cams at least.

 

It's when you rev to higher than stock RPMs that you should start worrying about your valvetrain not holding up. You should be fine.

 

103, thanks for reminding me that me that I can rev to 8 grand in my gsr. I guess I forgot. And watch who you call a shmuck.

 

I meant 137

 

I take my to 8800 on a regular basis. No prob.

 

i got the itr intake cam....is it safe to bring it above 8000 in my 97 gsr?

 

You forgot what the redline of your car is? WTF?

 

damn guys all he asked was if the stock valvetrain could hold out with ctr cams, not to be verbaly bashed!

 

you can put some damn monkeys in the valvetrain instead of your stock cams, if you don't change your redline from the preset ECU limit and you'll still be safe. Sorry, had to say it. I'm sorry if he's not to techical and doesn't realize that if his ECU isn't modded he's fine.

I always thought that the redline on the car was put there under the assumption that you did not have higher lift and longer duration cams. I guess I could be wrong though. I also I guess I can put some Toda Spec C's in a B16 on the stock valve train and not worry about valve float as long as I stay under redline.

I it a legit question on his part so dont think that he is a moron or not technically inclined.

 

Hi,

I ran the CTR intake cam in my GSR with stock redline for awhile and it was ok. Course, I eventually burnt a valve on some nitrous but that's probably a diff story.

I "'think" you could make a little more power if you raise the redline slightly, to say 8500 rpm. Click the link to the DFH page and go to the Tuning section to see my old dyno. Peak HP was right at redline.

Also, the CTR/ITR cams have a little more lift than the GSR cams (CTR intake cam has 3 degrees more duration than ITR). Honda chose to upgrade the valvetrain on the ITR. To be safe, and especially if you raise the revlimit, I would recommend that you change to ITR spec valvesprings. Better safe than sorry.

Think of the added wear even at the stock GSR redline dealing with more lift... If I were to do it again, I wouldn't risk it.

Also, you get stiffer valvesprings to help prevent valve float or binding, but at the same time, you may make more power with slightly less stiff valvesprings. If they're too stiff, you add friction and whatnot I think. Also, get some Ti retainers and whatever else you can do to lighten the valvetrain. This should help with reliability and power.

So, I guess you probably "could," but maybe you shouldn't

Dude, you're flaming him and sounding like an idiot. The valvesprings Do Not hold cams in place. The valve springs only pull the valves closed after the cams open them. go read a book before you call decent people asking decent questions a shmuck.

Yeah, and what people are saying true, you'll be fine with any of the ITR/CTR cams with and 8K redline on a B16a/B18c. I've run them in couple motors with no problems. The lift and duration isn't enough to float the valves. But however, this isn't true with any cam. Ie you can just slap toda C's or Jun 3's in an expect it to work (It could blow right away, or a year later after the springs are worn down).

 

you took the words right outta my mouth TypeC

 

Getting Toda Spec C's or JUN Stage 3's or ITR or CTR cams are best used in your engine with new valve train components that allow you to raise your redline to take advantage of the more aggressive cam profiles.

 

Thanks to those who had postive replies. And to the one who said I wasn't technically inclined, I am more so than you think. I understand that if the stock redline is kept (stock ecu), then it should be safe. All things said, my question was if the stock gsr valvetrain(valvesprings) could take the additional lift provided by the ctr cams. Not the fact of raising my redline. Thanks again to those who were helpful. Later.

The answer is yes. You will not get valve float unless you rev higher than 8,300 or so. Honda always goes a little on the safe side. Also unless you are getting coil bind from aftermarket cams, you will never have a problem with revving to 8K. Well as far as the cams are concerned.

 

TypeC hit the nail right on the head and it was not a stupid question so don't sweat it. (I think the inaccuracy of the original flame shows how off base the flamer was)
