Works the same with cars aerodynamics. High pressure to low pressure creates turbulence which creates drag.

 

I had Tyler and Pete install them a few months back along with the p2 reflash and they also installed my sp downpipe 3" and turbo xs rfl 3" catback and perrin 3" test pipe with the o2 eliminator..lol they made me bolt on the last bolt for the test pipe for legal reasons. Got a kick out of that. I actually had the p2 done first and had installed my hks suction intake myself. I was amazed at the difference. But once I got the turbo back exhaust on with the 269 cams it was like night and day. The car just hauled *** period. I'm waiting on dyno or 1/4 times till I dump the stock clutch but I can tell you the 269 cams make the car extremely torqy. It moves through the powerband much faster and all the way to 7800rpm if you have the p2. Already killed a Camerco SS on the freeway up to 145 with the current setup which was pretty cool. I would have never expected that. He shut down and i followed him and we talked for a bit. He has a new found respect for the EVO now. He knew they were fast but not that fast. Anyhow I'm done with my rant on the cams..they're great..get them if you can. You'll be very happy.

P.S. Tyler, Pete I'll be back soon for the throttle body

 

We got one with your name on it buddy!

 

I chopped out some, but I thought this was a great post out in the Evo Engine forum on overall cams. Can you guys answer the top questions from the 269 perspective??
Personally, I'm looking for something across the power band. Mostly a street car, occasional drag and possible track - but mostly street as a daily (fun) driver. I don't want something that will stall!

 

I have the 269 cams, ful works exhaust, throttle body, P2, and the package works together brilliantly. There is always power on demand, which will be very usefull in track and autocross situations. Huge, fat torque curve, which the cams contribute to immensely. Dynoed my car recently at S-squared's Mustang Dyno in sacramento, stock Sti's put down about 215 on that dyno, and I dynoed at 245 (thier dyno consistently reads about 15-20% less than most dynojets). So you figure 30 WHP more than a stock STI, and you are looking right in the range of 330-340 HP (Crank). So, the package does what it advertises. I love it. The only thing I want to add is water injection, so I can get a little more of a radical tune with the same margin of safety.

Thanks for the writeup. I got nearly 40hp from just the P2 (dyno-proven), so with my Turboback, I'm already estimating myself close to 340hp on 93 octane. So I think the 269 cams would be a sweet addition and hopefully tons of safe power throughout the band.

Any other comments? Can someone from works comment on my earlier post?

 

Always envy you gus that can get 93 Octane...it's been shown time and time again to be worth 15-20 WHP ont he state of tune that I'm at now. You will love the Cams, it will be a great final addtion to what you are running now, and give you that feeling of torque on demand.

The 269 cams idle suprisingly smooth. In addition, I don't know if the WORKS guys have mentioned this, but they smogged a set of 269's on a stock Evo and they came out cleaner than stock. Don't know much more, might want to ask them about it.

I plan on getting some 269's as soon as finances allow it. I hear nothing but good about the WORKS cams. I've been to their shop and have spoken to the WORKS engineers for hours on end. Their tuning philisophy doesnt have room for wasting time on useless products. Rest assured that their products are HEAVILY researched and tested over and over again. Their products may not always be the biggest, the shiniest, the most extreme....but from my experience, they seems to always deliver and keep me happy.

Just my 2c!

PS - For folks that want more extreme products, the WORKS guys are telling me to stay tuned for something called the WORKS Racing Program, where there will be more extreme stuff (P3 flash?) that will cater to those that want the 3" pipes and the high boost applications.

 

Right On.

I agree. The cams are excellent, power is added everywhere, and they nicely fill in the gap up top.

Hey guys,

Just wanna know whether the 269 needs to change the stock oem valve springs & retainers??

Is there a need to upgrade to cam gears? if so what is the settings?

Please advise..


Thanks....

 

And the answer is:

1. No, oem valve springs and retainers will do fine.
2. No need for cam gears.

Get them installed and enjoy. I am hoping to get my 269s in the very near future.

 

GREAT!!!!

Do u need to upgrade the stock fuel pump with this 269 cams?

Currently, my mods are just mainly bolt-ons...like,
1) 2.75" Str8 thru exhaust including catback
2) 3" DP
3) HKS EVC (22psi for max currently & tentatively ;>)
4) A/F controller
5) Apexi Cone air intake
6) HKS Groundings (DIY)
7) Hyper Voltage MR Stabilser
8) Greddy Type S

THanks......

 

You could upgrade your fuel pump if you really really wanted to, but I don't think it's necessary at all with your current list of mods.

 

Alrite....THanks mate!!!! This realli put a peace to my mind.........

Y do the HKS 272 needs the retainers & valve springs to be changed???

 

HKS 272s don't require the change that I know of. My friend runs 272s and has yet to change his springs and retainers and it runs great.

Now, something more lift like Piper Rally cams with all their crazy amounts of lift would require upgraded valve springs and retainers.
