Which Camshaft for best Low and Midrange Power? - Honda Prelude Forum

precisionelite · 02-25-2006, 03:24 PM

Here is my setup:

AEM CAI with Apexi Filter
Skunk 2 IM(not the pro-series)
Hondata Intake Manifold Gasket
Spare H22 Head with Skunk2 Valvesprings and Titanium Retainers
T1R Header (2.36'' collector)
Test Pipe (2.25'')
Thermal Exhaust (2.25'')
P28 ECU with Hondata S200.
Planning on getting some cam gears to help fine tune my power band.

My main goal is not just peak hp. What I want most is an improved bottom end response(under 3k), an improved midrange response(5-7k), with top end power being a secondary consideration. I'm not planning on doing any headwork or swapping pistons. What do you think would be an appropriate camshaft for me? I'm between the Crower Stage 2 and the Skunk2 Stage 1. I'm open to other options as well, provided they'd meet my power band critera. Thanks for all the help gang.

P.S. Any suggestion of products to buy to help my power are welcome.

look at my graph curve with the crower stage 2 non-stock idle.... made 191 WHP, and increase in midrange

looks like you got a good setup currently, with any cams, even type s cams, you can probably make up to mid 190s with tuning. go with cams that you wont require upgrading valvetrain since you dont want to mess with that stuff.

its actually takes a lot more to break into the mid 190s.....

You got the wrong intake manifold if you are looking for low and midrange performance.

Haha tell me about it man! In hindsight, I should have gotten the Euro-R or Blacktrax. I can tell you all that my midrange (5-7k) definatly feels a lot fatter. Although I'm not sure if its all the intake manifolds doing, since I installed my T1R header and test pipe at the same time as my IM.

I forgot to mention that I have a spare H22 head w/skunk2 titanium retainers and valvesprings :-).

you never know

My last dyno was 185WHP. Not sure if it was SAE or not but it was eaisily 93 degrees inside the dynoshop so i'm not too worried.

h22terror · 02-27-2006, 06:31 AM

i also have crower 2's that i just put in, and coupled with my rmf they make excellent midrange power, untuned.

eolife22 · 02-27-2006, 08:23 AM

I say since you already have springs and retainers....buy some crower stage 2's or skunk2 stage 2s......doesnt really make since to get stage 1 if you already have your head built up some what........Im looking to make atleast some decent HP with the mods I have listed below and add ons like Skunk2 Stage 1 cams....AEM Pullies....ES Mount Inserts, and AEM Cam gears...I say I will prolly make 170 WHP with those mods....so I think you shoul be pretty damn close to 191 WHP

camarokiller · 02-27-2006, 09:16 AM

^^^ I agree. You already have a spare head with springs and retainers. Just get a set of crower stage 2's, as they have good midrange and top end power, and sell/replace that IM to get more midrange. Also, underdrive pullies = more low/midrange power.
Anyone have any suggestions for him as to an intake that provides the most midrange?

I just talked to my local speed shop, they actually said with stock compression the type s cams are the best. I believe them, they have an H22 hatch with 250-260 HP. They tried just about every cam for it. He said the Crower Stage 2 was a big cam. I'm thinking of brining it to JDM spec, Euro R mani, w/type s cams.

i have done no research on this, but i heard that running turbo cams will significantly increase you're low end power.

Paperchasin · 02-27-2006, 09:38 PM

ever consider the Jun setup? stock idle....not sure what "stage" their cams are tho...

camarokiller · 02-27-2006, 10:09 PM

Jun cams have really high lift from what I've heard. Probably not the best for midrange power.

BLACKISWHACK · 02-27-2006, 10:36 PM

i just bought some type s cams, if i dont like them ill sell it

precisionelite · 02-28-2006, 02:30 AM

Let's Compare the Crower Stage 1's to the Type S cams.
Crower Stage 1
Intake Duration: 307 Lift: .459
Exhaust Duration: 318 Lift: .428

Type S
Intake Duration: 306 Lift: .469
Exhaust Duration: 310 Lift: .438

The crowers have more duration, while the type s cams have more lift. I'm not sure how that will translate into performance. The Crowers will probably have ruffer idle than the type s's, because of the increased duration. I don't know if it will even be noticiable though. Experts chime in please

precisionelite · 03-03-2006, 10:10 PM

I'm leaning towards the type s cams. Since the S cams arn't that dramatically different from stock will I experience rocker pad damage because of the skunk2 springs?

precisionelite · 03-09-2006, 04:28 PM

I've decided to ditch the Skunk 2 Titanium retainers in favor of Crower's Chromoly ones. I don't want to have to swap them every 25-30k miles, this is my daily driver after all. Is it safe to run Crowers STD. height chromoly retainers with the skunk2 springs?
