Delta Cam Stage II - Anyone used it?

[prototype]

I tossed an email at Delta a few days ago telling them what I had done to my car and was wondering if the stage 2 would be fine for a more or less stock engine. They told me sure thing, my question now...

How good is it? It's only 93.50 plus shipping to get them to grind it. Compared to the other company in canada, lots cheaper.

5hp gain? or more like 30hp gain? Let me know, thanks!

Wondering this myself and also if Colt's "Tri Flow" has any substance of if it is just marketing.

[2ndGenGuy]

How is that "lots cheaper" than the Colt Tri-Flow? I paid ~$100 + Shipping for my Colt Stage 2 cam...

Plus Colt tosses in a 5 year warranty with their cams, even for race conditions. And they're super-friendly, easy to deal with, and are great at letting you know whats going on.

Colt has $180 listed on the site.

If it's a more or less stock engine what could you have talked about to Delta?

You won't get 30bhp from a camshaft it's not like adding a turbo!! Your likely to gain a few bhp not a lot with a stock engine all you'll be doing is shifting the power band further up into a region where your rev limiter will cut in!! so you'll have a really narrow powerband. On one of my engines a stage 2 camshaft will be good to rev to 8-8.5k rpm so if your power's kicking in at 4000rpm and being cut off at 7k your missing out on another 1-1.5k rpm of power at the top. Also you'll gain loads of midrange loose the top to the rev limiter and you won't have much down below 4000rpm and it will idle badly as the duration is higher.

Stick to a stage one on stock engine and when you get round to doing a proper engine then use the stage 2 or higher.

You can gain 30bhp or more from a camshaft but thats only after you've done the following:

High CR forged pistons
Some quality headwork
Bigger valves
Good quality Header and 2.25" system
Twin Weber DCOE's or set of ITB's
Crank fired twin coil ignition system
for 7k rpm plus revving you need an engine thats been balanced and blueprinted to perfection or it will just wear itself out dead quick!!

Spend your money on something else like some better tyres or some better brake disks or pads.

Also although your only buying a camshaft your supposed to use new rockers with any new cam or re-profiled cam or you'll damage the cam and wear it out unevenly. so you need to budget for 12 new rockers too. And if your head has done a lot of mileage more than 60k you'll wear out the valve guides quicker too even faster if their allready badly worn!!

Estimated and prototype, what mods do you have so far? A camshaft IMO should be one of the last bolt on mods done. Start off with I/H/E, camgear, B18 intake manifold. Once you do that then get a head and bring it to a shop and have them rebuild it, port it and install the camshaft. If you do that then you will see nice gains. And if your trans is an auto then look into a 5-speed swap.

Proto,

I have the Colt Stage 1 and as jrudgy said the difference doesn't kick in until after 3500rpm. My biggest set back is the fact that mine is auto...so I have absolutely NOTHING at the bottom end. On the top end my newest top speed is 190k which is near the 120mph mark. That's with CAI/Header/2.25 exhaust and soon to be Adjustable Cam Gear. So I need to swap my tranny and I'd like to drop the suspension...and all this started with me thinking I'd put a K&N filter in the stock intake system.

Personally I blame all the usual suspect on this site (wink). And "yes" that includes the last two guys that have posted LOL

[Vector]

yea... anything under 3500rpm is about the same for the triflow stage 2, but after that it pulls right to the rev limiter.... at least for me it did, was a nice improvement over stock... when i had the itbs on there temporarily... after 4k rpm.. that engine hauled ass for having 320,000k's on it... then i broke the broke the intake.

[bobafett]

wtf is a stage 2 cam?

are you talking about 272, 282, 292? 272/282?

i believe its the 282 for stage 2

[bobafett]

in that case. a 282 is great on a stock engine, but probably not enjoyable until you have other boltons like exhaust and some form of intake.

zeph rocks a 282 cam with quad carbs, and full exhaust, and his car is way quicker than a stock accord. :) but he also knows how to tune it....

you will probably hate the powerband though. until 3500 rpm it literally feels like you don't have your foot to the floor, but at 3500 it screams and takes off...

[MessyHonda]

how about a tri-flow cam....for low end power

[prototype]

I see a lot of responses about rev limiter... I have the heavy modified stock keihn, mechanical secondary, etc. Also, trannsmission is a 5spd integra hybrid. No CAI, simply going to have a nice little filter on the top of the 2bbl.. And I plan on getting the full legnth header setup from pace setter and running the pipe through a small glass pack and kicking it right out the side of the car with a shinny "little" 3 inch tip.

282 duration, good till about 8k eh? I took my 87 accord with stock cam and everything to 7500 a few times, never made any funny noises, just didn't flow too well past 7k.


The car has been sitting in the shop for some time, it's a constant work in progress. I have another car for a daily driver so I don't need to worry about building anything in a specific order. I just want to shoot for a good 150 hp or so N/A without having to do too much work to it.. Then it's off to the paint booth. :)

Thanks everyone for your help so far.. Hope that clears it up a little.

Noob question here but I'd rather not find out for myself. When does the rev limiter kick in for an a20a3?

6500-6950 depending on if its standard or auto, but thats fuel cut, so realisticly i believe its 6250 or so to hit the red portion of the tach

[MessyHonda]

yeah our fuel cut off is 6950...but our tachs are wack....its its like the red part of it...

[snoopyloopy]

that must be for 5-speed then? because mine bounces at around 6500. feels like a damn wall.

[Cheeseburger]

wOOt

[MessyHonda]

lol...yeah 5 speed. i only hit it like 2-3 times....not good at all....but the 3rd gear pull was nice. specially beating my friends 03 jetta....

[A20A1]

their is no carb rev limiter but their is a fuel cut, so if it cuts the fuel and you're reving on air don't expect the engine to like it :)

[rjudgey]

Well that makes things a little clearer.

Your still wastin your time with the stage 2 with the setup you have.

You go tthe box which is good start.
Now with carbed engine (unless you got a rebuilt injection engine) the CR ratio is lower so i'd seriously look at doing a partial rebuild with new Honda A20A3/4 pistons, then shave a bit of the head while it's off clean it all up inside 3 angle seats or better re-new everythign you can. Then bolt back together and you should have CR ratio of around 9.6 to maybe 9.8:1 depending howmuch you take off the head maybe bit more.

Then get your inlet manifold cleaned up and flowed inside, get a Weber DGV 38/38 upgrade the pump maybe and regulator for weber and then you can think about a cam with 280 degrees duration but even a 260 would work really well you should have excellent power upto 7k with this or with a 280 upto 7.5k i would imagine your current setup although revvign to 7.5k you have next to no power from 5.5-6k rpm onwards and your just being cruel revvign it past that i tried stock cam in one of my race engines just for shits and giggles as i was bored one afternoon and boy was it crap no power and revved to like 5k before running out of any useable power when i qoute rpm figures the engine actually has full power at these rpms. Also headwork guy's and the inlet system hugely effects the rpm's of the engine and where your peak power is going to be i don't expect anyone to have an engine that revs as high as mine and has such a high peak powerband because not being funny no one has done the smae amount of R&D into Honda heads as i have but even basic mods to induction system and head will give you good increases so it's worth doing and worth doing properly.
