So we got a set of the new Kelford Stage 1 cams and put them on a back to back test against the stock K20A2 cams!

Stock K20A2
-Short ram w/ dirty filter
-4-2-1 Header
-N1 Catback
-91 octane fuel
-AEM Ems
-MAP Fuel regulator kit
-AEM FPR
-Hybrid Racing fuel rail

The Kelford 179-A Stage 1 cams can be used with stock valvetrain. Making these a very quick install.

They do REQUIRE tuning though.

Attached is the baseline with K20A2 cams and then the Kelford stage 1's with a quick tune.

Also a couple pictures we snapped during install.

I will be putting a cai w/ new filter on soon and testing some more!

Big thanks to Kelford, Hybrid Racing, and AEM for all of their support and quality products!








So that's a 9.5 Horsepower Gain and 6.5 ft lbs of torque increase!

i use kelfords in my turbo dsm, great cams. worth every penny.

Kelford is very well known in english racing. Their products work incredibly well.

So you didnt TUNE the car on the stock cams? Just a basemap from the AEM?

Maybe I read that wrong but it looks like that is what you meant...

Also, the stock cams had a lot more in the mid-range than the Kelford's but they obviously made numbers for the dyno.

I would be disappointed to lose 5-10 ft lbs of torque in the sweet spot of the graph but I know most kids out there want the numbers.

The car had been tuned with the stock cams.

The Kelfords were popped in and tuned as well.

We'll be tuning with a cai instead of the hot ram with a dirty filter, soon. haha. I'm sure there is another ~10whp in it.

i appreciate the work companies like you are doing to get some #'s to the people. 10whp ain't that bad for what they're worth. especially if they've got more in em. overall though, i'm not impressed with them. seems like you could have a fatter powerband with 06+ tsx cams.

Stock tune looks about right, if those numbers are SAE numbers. Should be able to make more power up top and mid range with a different header.

Here is a test that I did to show where the stock rsx tuned is sitting at. Keep in mind that this is two different dynos and two different headers. So graph will look a bit different. Header was made for a stock k20a2 with 8500 rpm red line in mind.

Car: rsx type s
Engine: stock k20a2 (cams, pistons, rods, air box/filter, exhaust)
Both set ups were tuned via kpro by myself.
Only difference between the two graphs is the header.

Red line: stock header/kpro tuned = 177whp/135wtq sae
Blue line: 4-1 header/kpro tuned = 190whp/141wtq sae

?Donde esta TORQUE?

very nice engine..,right,,Kelford is very well known in english racing. Their products work incredibly well. They also sell a good quality Fuel Pump..

Why, this aint a tractor pull? The motor makes more average HP now therefore would have more thrust and would out accelerate the same vehicle with the former. In racing, drag or road, the engine will spend most of it's time above 6000 RPMS anyway.

0xenocron

in a STREET car where stage 1 cams would be used, the driver would spend a majority of the time BELOW the RPM where cams start to make more power. If this was a drag car or a race car that spent most of its time in the range where the Kelfords made more power...I would agree.

plus i didnt see an answer where the stock cams were tuned...if they were just baselined on a base map, then I dont think its the greatest test of these cams.

Don't mean to jack thread, but I'm seriously considering Kelford stage 2 cams along with valvetrain upgrade, but from what I've searched, can't seem to find any dyno numbers with stage2 cams... can anyone please direct me to any dyno result for stage2 cams? btw, I currently have z3 in my ep3 with Kpro, Kidracing krusher RH, SRI, ws2 exhaust(will be replaced with 3" setup w/ cam mod). Big thanks in advance and once again my apologies to OP!!!

Kidnkorner

Street, race combination of the 2, slower is slower.

I'm not pulling a boat and if my STREET driven car would be faster and have more average HP then I will take my 5000-8000 RPM HP over mid range torque ANY DAY.

autoxmnstr

Any comparo's with z1 cams? Or a whole z1 motor. The A2's aren't really agressive at all, not suprised by the result but good write up none the less.

nahonda04

do you have any graphs of the stage 3's/monster cams with similar mods...i a debating on those or BC stage 3's

texm3x

wow i thought these cams would throw more power

jdmcivic2fast

exactly what i was thinking

i believe he did say they tuned the stock set up then cam swap retune.

Uncle Dave

If that was my setup I would be very unhappy with losing power under 6k,I have spoken to Kevin@Kelford alot over the years and find them the best cams in EVO's but the K20 needs more work on the low cam it would be good to see these in a K24 combo.

egvera89

that's pretty good info to know and to be able to actually see a dyno graph to prove it.
