TTP, do you run HKS 280s right now?

 

Are these 280s>272s on a stock turbo? man I just recently installed a pair of your 272s. Please post the results when you guys do the comparison.....

 

Well sort of...

 

Very nice job GSC!

 

scott that there manifold looks a little white inside! whatcha been running in that thing ;-)


evo rc martin at ams is going to switch his white cars cams(presently on our 272's) with the new 280's, but you know how much he likes posting dyno charts.

 

So is that the cam gear setings that are soooooo secret (127mph) 0/0 ?

 

Any idea on how this would perform on a 2.0 with a 50 trim?

 

+1

 

yup interested in how it perform with 2.0 & 50 trim too!

 

The dyno operator just opened the throttle later; I'm sure the cams are totally fine at sub 4500 ranges.

 

that is 46mph not rpms. and second it has to do with where the log starts on the dyno. Sooooo basically if you push the button before you step on the gas that is what happens vs the first run which shows that the gas was depressed then the log button was pressed. just a sampling deal. no biggy nothing to do with power.

as far as a 50 trim goes they will work great up top. make more power than 272's. they are going to suffer some under 4k rpms nothing crazy tho and anyone running 280's already wont notice the bottom just the topend.

On at 2.0 with a 50 trim, what will idle quality be like if I'm using a stock ECU with UTEC?

 

That is the question that will keep a lot of stock ecu folks from trying these. Until a test is done with these on the stock ecu, I wouldn't take the chance on these or any other aggressive cams.

 

No I spent a lot of time brainstorming with him on chasing down a phantom knock problem that happens at 15% throttle and cruising.

He tried everything from going back to stock manifold for a day (pictured) to switching dowel holes and 0/0. He finally just pulled the head to inspect the HG and it was fine also. Frustrated to say the least.

I asked the same question when I saw that pic. LOL

 

Greg, since these cams are released now, will you please list the specs such as lift, thanks!
