cam combination question

[RedGST98]

Stupid question but gotta ask... I have a Holset H1E turbo not running anythng over 23psi atm till im able to upgrade the lower end some.. but heres the stupid question...

I am looking at cams atm... first off what would be the best combination in you guys opinion.. 264/272 or straight up 272/272.. I heard that with holsets its actually better for a faster spool time with the 264 combo is that really true?

and how bad are BC's really.. or should I go with the trusted Kelfords??

I am leaning to the KC's and the 264/727 combo but would love some input...

what compression are you running on your engine? 23psi with a holset H1E turbo I would recommend sticking with the hks 264s with stock cam gears. I did a cam test a while back and I ended up running the bc 272 cams for one reason only drivability! I run them installed straight up with stock cam gears they spool almost identical to my old hks 264s but has a little more power up top I can't say how much I love their street manners here is a dyno comparison of the hks 264s vs the bc272 the car started to run out of fuel that is the reason for the dip up top.

its stock compressiion .. eventually will be going to 9:1 standard bore... so the 264/264 or the 264/272 are you talking about?

Its still my DD but jsut want enough that when someone wants to play.. im there to say what happened thought you wanted to race..
