Drift... H22a cams?

[sparq]

Drift, are the Crower cams (or any for that matter) affected by I/H/E etc. ? Like Crower says 12-15hp for the street/strip cams, but what if you have I/H/E, bigger throttle body, better intake manifold etc. Will I see more power, or would it be like, the cams provide more low RPM power, and then when I get up into the higher RPM the I/H/E do the work etc?

Like the Skunk2 intake manifold says 8-15 dyno proven wheel HP (probably hype, but still) and with the throttle body (says 5-10% increase... im guessing at the crank, so only would probably see what like 3-4 more ponies at WOT when im pushing redline? I want to keep it all motor, but want a little more sofistication then just I/H/E and thats why I thought of the cams ~ any other ideas? My friend can port and polish for me... just wondering what kind of gains that will give if any?

Thanks for any help Drift, or anyone else who wants to help!

all those things have to work together. sure the cams alone will yeild results but even more power can be had by improving around them. obviously if you put a bigger cam in then your air ingestion and exhaust output will be affected so you will want to upgrade to systems that are more capable of giving your motor what it needs, see what im sayin?

so if you throw a huge cam in, then you can only benefit from the increased air flow of a ported head, or bigger vlaves, or bigger throttle body, or intake, or exhaust or header. its just matching your selections so the individual components work the best with each other then fine tuning it thats the pleasure and pain.

hope that helps homey

yes... bolt ons will help with the install of larger cams. the less restrictive bolt ons will help the cams make more power due to less restriction to airflow.

So do you think that I might actually see "real" numbers if I did go with the cams?

What I mean is like places how the HP gains listed...

Crower Cams (12-15hp)
Skunk2 Intake Manifold (8-15hp)
DC Sports CAI (7-10hp)
DC Sports header (10hp)
DC Sports exhaust (10hp)
Bored out throttle body (10-15hp ~ based on 5-10% power gain numbers by "Ericks")

Mmm, thats what 57-75 hp... Do you think with proper tuning (good ignition system, upgraded fuel delivery system, cam gears etc) that I could honestly expect to see this power (if not at the wheels... which im not sure about because most of these like the crower, dc sports, and skunk were gains measured @ the wheels) ???

And switching to like a Comptech lightweight flywheel, is there any sort of gain? I mean most drivetrain loss is figured as what what 15%? Would it only be like going from 15% to like 13% loss, or more like 15% to 10% ??? Or ??? Looking for answers

Sparq, those mods are for the motor you're sending me right?

First off, those power gains you qouted are not meant to be straight cummulative, they are just maximum power gain numbers to be expected only on a small percentage of engines and setups. Besides, most of the numbers you qouted aren't even accurate...

1- Skunk2 doesn't make a manifold for the H22.
2- DC Sports doesn't make a CAI, they only hav underhood intakes and on the Prelude have been shown to hurt power output. Check www.hondaprelude.com and read tec9-7's article about quarter mile times with various intake setups.
3- DC Sports 4-2-1 header for the Prelude has shown maximum gains of about 3hp, the H22A4 in particular has a great 4-2-1 header from the factory.
4- You'll be lucky to get more than 3-4hp out of the exhaust too, particularly on the '99-up 5g Preludes the stock exhaust system is near perfect.
5- Lightened flywheels don't decrease dirvetrain losses, they siimply take a bit of inertial loading off the engine.


There are a ton of other points to make here about NA engine tuning, but we'll leave that to another bunch of posts. If the engine is in good condition and you get the tuning sorted out on the setup, you should expect to see around 200hp to the wheels.

sparq, your the biggest paper pusher i have seen. get a car then ask questions. it all changes when u get a car.
