What will i have to do to my d16z6 to make it safe to rev higher than 7200? Will these upgrades make power past the stock red line?

 

Why do you want to rev higher anyway?

Adding performace parts to an engine is usually done to gain power, not RPMs.

 

I dono i just want to haha flameeee. But if i get a cam and redo the head with better components will it make power past 7200?

 

I think your goal should be to make power before 7200 rpm.

But hey, if you want to have to rev like hell to make power, knock yourself out and your engine with it.

 

your singlecam engine has a very poor port design which can only be fixed through extensive portwork and flow testing, by the time your done buying the time on the flow bench, a good cam, and valve train you could have compled a twin cam swap. just something to think about.

 

like they said why?? you need to have it balanced and blueprinted, upgrade ecu and so on need a grip of cash to do it

b/c he'll be boosted and will be making power above 7200 rpms

 

the reason to up the rpms would be to increase the area under the curve: a.k.a. what really matters.

could someone actually answer the question. i know it depends on how much higher one would like to go but give examples as to the limits of the stock head, stock bottom end, etc. and the options in dealing with those limits

 

if you really like the single cam motor great, stiffer springs and a flashed ecu will let it rev higher but dont think higher revs means more power.

 

you get a chipped ecu that lets you exceed the rev limit it wont matter, you'll feel a dramatic loss in power. you should actually feel a dramatic loss in power after 6600 rpm, since that is the peak torque in rpms for a d16z6. even with new cams, it wont make a difference, unless you had forced induction. but if you were getting any type of forced induction, you should already know the steps you must take to ensure that you dont abuse your motor. cams, rockers, valves, retainers, pistions, block guard.

 

i have the camshaft and valvesprings and retainers to make the power all the way to 7200 and more for sale if your interested just lmk wsup

Hrm, well, unless I am misunderstood... it isnt the torque alone that determines power dropping... if the HP is still higher than the rate that the torque rate is dropping, it should be able to maintain that level of pull...

Gurus please correct me if I am wrong... but wouldnt it be right in stating that? That as long as the HP is still higher,.. it wont pull harder, but the same power/pull will be extended through the rest of the RPM band until the TQ drops faster than the HP can make up?

 

I heard somewhere that stock valvetrain can handle very very high revs on a sohc(I upgraded them anyway). Upgrade to arp rod bolts, stronger rods, and headstuds and you should be ok. Rods is a big deal, stock ones are tiny.

 

horsepower is not actually a measureable value, it is a direct relation to torque varying by rpm, ie:100 fp torque at 3000 rpms is less horsepower than 100 fp of torque at 7000 rpms, so when torque falls drastically at high rpms horsepower potential is lost due to its direct relation.

 

A sohc 2v motor will have trouble breathing at a higher RPM, no point to it. Worry about making power in the rpm band you already have.

 

i don't know why some people are saying he won't be able to make power higher than the stock redline with a different cam. Depending on the cam you get you could possibly make power higher than the stock redline. You may want to look into the crower stage 2, zex 59300 cam, skunk2 cam etc. Also i would go ahead and upgrade your valvetrain if you are gonna be revving higher.

 

rgr, I know it isnt measurable, but when the equation comes in, TQ can peak and fall, but because of what HP is, it simply is the extent the peak power is extended.... So... with TQ at high RPM you can take advantage of gearing, and potentially pull ahead of BIG TQ with short gears... blah blah... its sooo complicated...

the horse power vs. torque concept isnt complicated at all. hp is torque x rpm/5252. that is it. that is why the torque always is equal to the horsepower at 5252. when considering shift points and tuning for practical application, you focus on creating a usable torque curve. the hp made is just a pretty number

Yes, and here is a perfect example

 

i can just see the valves now :/
